小学英语教育存在的若干问题及对策摘要当前我市小学英语教育存在着教师资源配笠不足、教师整体素质偏低、教学教法相对落后等问题,本文从实际出发,正确分析我市小学英语教育的现状,并试图从不同层次寻求对策,为提高小学英语教育整体水平提供参考。关键词小学英语教育问题对策中根据国家教育部新一轮课程改革进程安排,新课程将于2005年秋在全国范围内全面推行。按照新的课程标准,小学3年级将开设英语课,3一6年级英语教学有了目标和内容上的级别要求。《英语课程标准》对英语教育提出了较高的要求:激发和培养学生学习英语的兴趣,使学生树立自信心,养成良好的学习习惯和学习策略,发展自主学习的能力和合作精神;使学生掌握一定的英语基础知识和听、说、读、写技能,形成一定的综合语言运用能力;培养学生观察、记忆、思维、想象能力和创新精神;帮助学生了解世界和中西方文化的差异,拓展视野,培养爱国主义精神,形成健康的人生观,为他们的终身学习和发展打下良好的基础。从学生发展的角度看,小学英语教育比中学、大学教育更重要,更关键,因为良好的语言开端将直接影响学生今后乃至终身正确掌握和使用语言,因此对照新课程标准,联系当前我市小学英语教育水平现状,找出存在的问题,研究切实可行的对策和措施,是提高小学英语教育整体水平迫在眉睫的工作。一、影响我市小学英语教育中的几个问题l、地方方言严重影响小学生正确英语发音。新课程标准对小学英语教育的语言技能教学提出了“在口语表达中做到发音清楚、语调达意”的基本要求。虽然普通话教学的要求在我市已经推行多年,但我市地处闽北山区,在相当多的农村地区和部分城郊,小学生的课堂用语仍常使用当地方言,英语与汉语本身在发音上就有着较大的区别,学生在接受普通话教育的同时接受英语教育,存在着一定的难度和障碍。而且,我市是地方方言种类繁多的地区,各地的方言不仅影响了农村地区的学生英语的正确发音,同样影响着城市的孩子。同时,多数小学英语教师也受地方方言的影响,自身的英语语音不准确。2、小学专业英语教师队伍配置严重不足。目前我市小学教师明显不足,特别是农村和部分县市的小学几乎没有,且许多现有的英语教师属非英语专业或是其他科任教师兼任英语教学,或是从其他学科“改行”教英语。3、小学英语教学理念和方法相对落后。从目前情况来看,我市的许多小学英语教育还大都停留在传统应试教育的教学理念和方法上,对英语语言的教学理念和方法还相对落后,一部分教师不了解语言学习的规律,教学经验不足,不能创设情景激发学生学习英语的兴趣,只让学生死记硬背,教学方法单一。教学基本上是照本宣科,重知识传授,轻能力培养。同时许多教师的教学观念仍停留在传统的“以教师为中心”的层次上,课堂是教师一言堂,填鸭式的灌输,忽视语言实践。对小学英语教学理念的研究和创新不够。4、小学英语教师的整体素质偏低。主要表现在几个方面:一是英语专业的水平有待提高。现有的小学英语教师多为中师、高中毕业或从其他专业改行,专业基础差,英语语言知识掌握不够正确、词汇量不足、发音不准等现象比较普遍,教师的英语口语和交际能力不强,不能用英语组织课堂教学,大部分教师听力水平较差,难以指导学生进行听说训练。二是缺乏教育学、心理学理论知识。相当一部分的教师对教育学、心理学理论知识不系统,不全面,教学中不能按小学生的心理特.点和生理要求、认识规律设计教学环节,安排教学活动。三是动手操作能力差。现有的许多小学英语教师在这方面存在着很大的欠缺,导致课堂气氛不活跃,学生厌学英语。四是教师的教研能力差。许多教师不注重学习教育理论、研究教学现状和信息动态,不研究总结教学经验,不乐于撰写教科研论文,更不知道如何从教科研中获取经验和信息来充实自己。二、解决我市小学英语教育的荃本对策提高我市小学英语教育的整体水平,最关键是要培养一支高素质的小学英语教师队伍。这是一项长期的系统工程,需要教师、学校、政府等各方面的努力和付出。笔者认为,可以从以下几个层次寻求对策:1、教师要加强自我素质的提高。小学英语教师应该清楚地看到自身存在的不足,有针对性地加强英语专业知识和其他有关教学理论的自我进修,坚持采取读英语书报杂志、听英语广播等多种形式,不断更新和正确掌握英语知识,提高教学能力,以《英语课程标准》中“准确把握新课程标准的理念、目的和内容,运用教育学和心理学理论,研究语言教学的规律。”、“善于结合实际教学的需要,灵活地和有创造性地使用教材,对教材的内容、编排顺序、教学方法等方面进行适当的取舍和调整”等的要求严格要求自己。2、学校要创造良好的教师发展环境。教师的专业发展离不开学校的改革与教研实践的紧密结合。校本教育对教师的专业发展有着不可替代的作用,既能适应教师教学和学校改革的需要,又促进教育理论和教育实践的有效结合。学校应为教师的反思实践、行动研究、参与课题研究提供资源和制度支持,及时提供载有学科前沿的读物给英语教师阅读,扩大他们的知识面。同时,学校要充分发挥教研组的作用,广泛开展说课交流,举行各类英语教学教育研讨会,开展“创优课”评选和“教改实验”等活动,不断促进教师理论与实践相结合,不断创新,推动教学向纵深方向发展。3、高师院校要有重点地培养小学英语教师。世界各国早在20世纪80年代初就取消了中等师范学校,小学教师必须由师范大专或大专以上毕业。我国近年来也将高师院校作为小学教师的摇篮。为此,我市小学输送急需的高素质的小学英语教师,加快小学英语教师大专化进程。同时,高师院校要根据新课改要求,在培养小学英语教师方面做好英语专业和教育理论的课程设置,改革过去英语教法课的教学内容和教学方法和只注重培养初中教师的做法,突出小学英语教师的理论与职业技能的系统培训,着力培养小学英语教师的基本教学能力、处理教材能力和教研能力。4、教育等部门要充分发挥职能。各地教育部门、负责教师继续教育的机构以及其他有关部门,要按照《英语课程标准》,全面系统地分析我市小学英语教育的现状,根据各自的职能,从高师院校的招生、课程设置、教师队伍人事的合理配置、教师继续教育和培训、小学教师教研目标要求以及开展素质教育所需经费的安排等各方面,综合研究和制定出合理有效的小学英语教师的培养计划,逐步建立起一套多渠道、多形式的培训网络,统筹安排英语教师的培训工作,全面提高我市小学英语教师的整体素质。综上所述,为了适应新课程标准的要求,顺利开展好我市小学开设英语课程工作,建设一支高素质的小学英语教师队伍,需要教育行政部门、学校、教师等各方面都责无旁贷。参考文献〔l]英语课程标准(实验稿)【M」.北师大出版社,Zonl.〔2」英语课程标准解读(实脸稿)〔M」,北师大出版社,2001.【3」刘昌春.农村小学英语师资培训当议【J〕.中国农村教育,2(X)3(12).【4」苏仁平.小学英语教师队伍存在的问题与对策【J].教学实践与研究,2001(12).

华文版本 Internet is a worldwide, publicly accessible series of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a "network of networks" that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked web pages and other resources of the World Wide Web (WWW).HistoryCreationThe USSR's launch of Sputnik spurred the United States to create the Advanced Research Projects Agency, known as ARPA, in February 1958 to regain a technological lead.[1][2] ARPA created the Information Processing Technology Office (IPTO) to further the research of the Semi Automatic Ground Environment (SAGE) program, which had networked country-wide radar systems together for the first time. J. C. R. Licklider was selected to head the IPTO, and saw universal networking as a potential unifying human revolution.Licklider moved from the Psycho-Acoustic Laboratory at Harvard University to MIT in 1950, after becoming interested in information technology. At MIT, he served on a committee that established Lincoln Laboratory and worked on the SAGE project. In 1957 he became a Vice President at BBN, where he bought the first production PDP-1 computer and conducted the first public demonstration of time-sharing.At the IPTO, Licklider recruited Lawrence Roberts to head a project to implement a network, and Roberts based the technology on the work of Paul Baran,[citation needed] who had written an exhaustive study for the U.S. Air Force that recommended packet switching (as opposed to circuit switching) to make a network highly robust and survivable. After much work, the first two nodes of what would become the ARPANET were interconnected between UCLA and SRI International in Menlo Park, California, on October 29, 1969. The ARPANET was one of the "eve" networks of today's Internet. Following on from the demonstration that packet switching worked on the ARPANET, the British Post Office, Telenet, DATAPAC and TRANSPAC collaborated to create the first international packet-switched network service. In the UK, this was referred to as the International Packet Stream Service (IPSS), in 1978. The collection of X.25-based networks grew from Europe and the US to cover Canada, Hong Kong and Australia by 1981. The X.25 packet switching standard was developed in the CCITT (now called ITU-T) around 1976. X.25 was independent of the TCP/IP protocols that arose from the experimental work of DARPA on the ARPANET, Packet Radio Net and Packet Satellite Net during the same time period. Vinton Cerf and Robert Kahn developed the first description of the TCP protocols during 1973 and published a paper on the subject in May 1974. Use of the term "Internet" to describe a single global TCP/IP network originated in December 1974 with the publication of RFC 675, the first full specification of TCP that was written by Vinton Cerf, Yogen Dalal and Carl Sunshine, then at Stanford University. During the next nine years, work proceeded to refine the protocols and to implement them on a wide range of operating systems.The first TCP/IP-wide area network was made operational by January 1, 1983 when all hosts on the ARPANET were switched over from the older NCP protocols to TCP/IP. In 1985, the United States' National Science Foundation (NSF) commissioned the construction of a university 56 kilobit/second network backbone using computers called "fuzzballs" by their inventor, David L. Mills. The following year, NSF sponsored the development of a higher-speed 1.5 megabit/second backbone that became the NSFNet. A key decision to use the DARPA TCP/IP protocols was made by Dennis Jennings, then in charge of the Supercomputer program at NSF.The opening of the network to commercial interests began in 1988. The US Federal Networking Council approved the interconnection of the NSFNET to the commercial MCI Mail system in that year and the link was made in the summer of 1989. Other commercial electronic e-mail services were soon connected, including OnTyme, Telemail and Compuserve. In that same year, three commercial Internet Service Providers were created: UUNET, PSINET and CERFNET. Important, separate networks that offered gateways into, then later merged with, the Internet include Usenet and BITNET. Various other commercial and educational networks, such as Telenet, Tymnet, Compuserve and JANET were interconnected with the growing Internet. Telenet (later called Sprintnet) was a large privately funded national computer network with free dial-up access in cities throughout the U.S. that had been in operation since the 1970s. This network was eventually interconnected with the others in the 1980s as the TCP/IP protocol became increasingly popular. The ability of TCP/IP to work over virtually any pre-existing communication networks allowed for a great ease of growth, although the rapid growth of the Internet was due primarily to the availability of commercial routers from companies such as Cisco Systems, Proteon and Juniper, the availability of commercial Ethernet equipment for local-area networking and the widespread implementation of TCP/IP on the UNIX operating system.Common uses of the InternetE-mailFor more details on this topic, see E-mail.The concept of sending electronic text messages between parties in a way analogous to mailing letters or memos predates the creation of the Internet. Even today it can be important to distinguish between Internet and internal e-mail systems. Internet e-mail may travel and be stored unencrypted on many other networks and machines out of both the sender's and the recipient's control. During this time it is quite possible for the content to be read and even tampered with by third parties, if anyone considers it important enough. Purely internal or intranet mail systems, where the information never leaves the corporate or organization's network, are much more secure, although in any organization there will be IT and other personnel whose job may involve monitoring, and occasionally accessing, the e-mail of other employees not addressed to them.The World Wide WebMany people use the terms Internet and World Wide Web (or just the Web) interchangeably, but, as discussed above, the two terms are not synonymous.The World Wide Web is a huge set of interlinked documents, images and other resources, linked by hyperlinks and URLs. These hyperlinks and URLs allow the web servers and other machines that store originals, and cached copies, of these resources to deliver them as required using HTTP (Hypertext Transfer Protocol). HTTP is only one of the communication protocols used on the Internet.Web services also use HTTP to allow software systems to communicate in order to share and exchange business logic and data.Software products that can access the resources of the Web are correctly termed user agents. In normal use, web browsers, such as Internet Explorer and Firefox, access web pages and allow users to navigate from one to another via hyperlinks. Web documents may contain almost any combination of computer data including graphics, sounds, text, video, multimedia and interactive content including games, office applications and scientific demonstrations.Through keyword-driven Internet research using search engines like Yahoo! and Google, millions of people worldwide have easy, instant access to a vast and diverse amount of online information. Compared to encyclopedias and traditional libraries, the World Wide Web has enabled a sudden and extreme decentralization of information and data.Using the Web, it is also easier than ever before for individuals and organisations to publish ideas and information to an extremely large audience. Anyone can find ways to publish a web page or build a website for very little initial cost. Publishing and maintaining large, professional websites full of attractive, diverse and up-to-date information is still a difficult and expensive proposition, however.Many individuals and some companies and groups use "web logs" or blogs, which are largely used as easily updatable online diaries. Some commercial organisations encourage staff to fill them with advice on their areas of specialization in the hope that visitors will be impressed by the expert knowledge and free information, and be attracted to the corporation as a result. One example of this practice is Microsoft, whose product developers publish their personal blogs in order to pique the public's interest in their work.Collections of personal web pages published by large service providers remain popular, and have become increasingly sophisticated. Whereas operations such as Angelfire and GeoCities have existed since the early days of the Web, newer offerings from, for example, Facebook and MySpace currently have large followings. These operations often brand themselves as social network services rather than simply as web page hosts.Advertising on popular web pages can be lucrative, and e-commerce or the sale of products and services directly via the Web continues to grow.In the early days, web pages were usually created as sets of complete and isolated HTML text files stored on a web server. More recently, websites are more often created using content management system (CMS) or wiki software with, initially, very little content. Contributors to these systems, who may be paid staff, members of a club or other organisation or members of the public, fill underlying databases with content using editing pages designed for that purpose, while casual visitors view and read this content in its final HTML form. There may or may not be editorial, approval and security systems built into the process of taking newly entered content and making it available to the target visitors.Social impactThe Internet has made possible entirely new forms of social interaction, activities and organizing, thanks to its basic features such as widespread usability and access.Social networking websites such as Facebook and MySpace have created a new form of socialization and interaction. Users of these sites are able to add a wide variety of items to their personal pages, to indicate common interests, and to connect with others. It is also possible to find a large circle of existing acquaintances, especially if a site allows users to utilize their real names, and to allow communication among large existing groups of people.Sites like meetup.com exist to allow wider announcement of groups which may exist mainly for face-to-face meetings, but which may have a variety of minor interactions over their group's site at meetup.org, or other similar sites.Political organization and censorshipFor more details on this topic, see Internet censorship.In democratic societies, the Internet has achieved new relevance as a political tool. The presidential campaign of Howard Dean in 2004 in the United States became famous for its ability to generate donations via the Internet. Many political groups use the Internet to achieve a whole new method of organizing, in order to carry out Internet activism.Some governments, such as those of Cuba, Iran, North Korea, Myanmar, the People's Republic of China, and Saudi Arabia, restrict what people in their countries can access on the Internet, especially political and religious content. This is accomplished through software that filters domains and content so that they may not be easily accessed or obtained without elaborate circumvention.In Norway, Denmark, Finland and Sweden, major Internet service providers have voluntarily (possibly to avoid such an arrangement being turned into law) agreed to restrict access to sites listed by police. While this list of forbidden URLs is only supposed to contain addresses of known child pornography sites, the content of the list is secret.[citation needed]Many countries, including the United States, have enacted laws making the possession or distribution of certain material, such as child pornography, illegal, but do not use filtering software.There are many free and commercially available software programs with which a user can choose to block offensive websites on individual computers or networks, such as to limit a child's access to pornography or violence. See Content-control software.Leisure activitiesThe Internet has been a major source of leisure since before the World Wide Web, with entertaining social experiments such as MUDs and MOOs being conducted on university servers, and humor-related Usenet groups receiving much of the main traffic. Today, many Internet forums have sections devoted to games and funny videos; short cartoons in the form of Flash movies are also popular. Over 6 million people use blogs or message boards as a means of communication and for the sharing of ideas.The pornography and gambling industries have both taken full advantage of the World Wide Web, and often provide a significant source of advertising revenue for other websites. Although many governments have attempted to put restrictions on both industries' use of the Internet, this has generally failed to stop their widespread popularity.One main area of leisure on the Internet is multiplayer gaming. This form of leisure creates communities, bringing people of all ages and origins to enjoy the fast-paced world of multiplayer games. These range from MMORPG to first-person shooters, from role-playing games to online gambling. This has revolutionized the way many people interact and spend their free time on the Internet.While online gaming has been around since the 1970s, modern modes of online gaming began with services such as GameSpy and MPlayer, to which players of games would typically subscribe. Non-subscribers were limited to certain types of gameplay or certain games.Many use the Internet to access and download music, movies and other works for their enjoyment and relaxation. As discussed above, there are paid and unpaid sources for all of these, using centralized servers and distributed peer-to-peer technologies. Discretion is needed as some of these sources take more care over the original artists' rights and over copyright laws than others.Many use the World Wide Web to access news, weather and sports reports, to plan and book holidays and to find out more about their random ideas and casual interests.People use chat, messaging and e-mail to make and stay in touch with friends worldwide, sometimes in the same way as some previously had pen pals. Social networking websites like MySpace, Facebook and many others like them also put and keep people in contact for their enjoyment.The Internet has seen a growing number of Web desktops, where users can access their files, folders, and settings via the Internet.Cyberslacking has become a serious drain on corporate resources; the average UK employee spends 57 minutes a day surfing the Web at work, according to a study by Peninsula Business Services.[9]Complex architectureMany computer scientists see the Internet as a "prime example of a large-scale, highly engineered, yet highly complex system".[10] The Internet is extremely heterogeneous. (For instance, data transfer rates and physical characteristics of connections vary widely.) The Internet exhibits "emergent phenomena" that depend on its large-scale organization. For example, data transfer rates exhibit temporal self-similarity. Further adding to the complexity of the Internet is the ability of more than one computer to use the Internet through only one node, thus creating the possibility for a very deep and hierarchal sub-network that can theoretically be extended infinitely (disregarding the programmatic limitations of the IPv4 protocol). However, since principles of this architecture date back to the 1960s, it might not be a solution best suited to modern needs, and thus the possibility of developing alternative structures is currently being looked into.[11]According to a June 2007 article in Discover magazine, the combined weight of all the electrons moved within the Internet in a day is 0.2 millionths of an ounce.[12] Others have estimated this at nearer 2 ounces (50 grams).[13]MarketingThe Internet has also become a large market for companies; some of the biggest companies today have grown by taking advantage of the efficient nature of low-cost advertising and commerce through the Internet, also known as e-commerce. It is the fastest way to spread information to a vast number of people simultaneously. The Internet has also subsequently revolutionized shopping—for example; a person can order a CD online and receive it in the mail within a couple of days, or download it directly in some cases. The Internet has also greatly facilitated personalized marketing which allows a company to market a product to a specific person or a specific group of people more so than any other advertising medium.Examples of personalized marketing include online communities such as MySpace, Friendster, Orkut, Facebook and others which thousands of Internet users join to advertise themselves and make friends online. Many of these users are young teens and adolescents ranging from 13 to 25 years old. In turn, when they advertise themselves they advertise interests and hobbies, which online marketing companies can use as information as to what those users will purchase online, and advertise their own companies' products to those users.

Along with the our country economic development rapid development, the lives of the people level unceasing enhancement, the city uses to be day by day anxious, urges the building to face the direction is developing. This kind of high level civil construction repair needed materials and the way also more hasten the diversification, and along with uses electricity the load and coal gas consumption quantity enlarging, proposed to the fire auto-alarm system design is higher, a stricter request. In order to guarantee the people life and property the security, the fire auto-alarm system design has become in the high level civil construction design one of most important design contents. Presently based on the author fire of auto-alarm system design overseeing work in the high level civil building experience, proposed in present national related standard and standard unclear true detail shallow opinion, by for the colleagues to discuss and to point out mistakes.First, design basis The fire auto-alarm system design is a specialized very strong technology work, at the same time also has the very strong policy-type. Therefore, first should be clear about the following design basis: 1st, must grasp the architectural design fire protection standard, the system design standard, the equipment manufacture standard, the installment construction approval standard and the administration laws and regulations and so on five big aspects fire laws and regulations, and in practical understanding present country related standard and standard positive word: "Must", "be supposed", "to be suitable", "may" and the reverse side word: "Strictly prohibits", "should not", "not have", "not to be suitable" the meaning.2nd, must aim at high level civil building function, use and the protection object fire protection rank, earnestly carries out the present national related standard and the standard, earnestly treats the public security fire prevention surveillance department the examination and approval opinion.Second, fire auto-alarm system equipment establishmentFire detector establishmentOpens wide either the seal or the stair hall should alone divide the search coverage, and each 2 ~ 3 establish a fire detector.The first room (including guards against in front of smoke stair hall in front of room, fire elevator room, fire elevator with guards against the front room which smoke stair hall comes in handy) and the aisle should distinguish alone to divide the search coverage, specially front the room and the lift well, the scattered stair hall and the aisle are interlinked, has time the fire haze to be easier to gather or to flow, is the personnel disperses which saves goal with the fire prevention, therefore should install the fire detector. Regarding common elevator in front of room although is not the personnel disperses , but this front room and the lift well are interlinked, has time the fire haze to be also easy to gather or to flow, suitably alone divides the search coverage and installs the fire detector. The electric cable shaft therefore is easy to form pulls out the smoke inflammation the channel; Has when the fire the fire intensity not easily extends along the electric cable burns, for this, "the high level civil construction design fire protection standard" and "the civil construction electricity design standard" separately proposes the detailed specific stipulation in the construction and in the electric wire or on the electric cable shaping. But considered implements specifically the difficulty and the present situation, the electric cable shaft installs the fire detector is extremely essential, and coordinates the shaft the fire protection separation request, each 2 ~ 3 or each level installs.The elevator machine room should install the fire detector, its elevator is the important vertical transportation vehicle; Its two elevator machine room has has the fire risk; Its three lift well existence essential opens the hole, like the level gate opens between the hole, the air vent, the between permanence opens the hole with the elevator machine room or the pulley and so on; Its four when has the fire, the lift well often becomes the fire intensity spread the channel, is easy to threaten the elevator machine room the facility. Therefore, the elevator machine room establishes the fire detector is necessary, crown of also suitable establishment fire detector lift well.2nd, the manual fire reports to the police the button establishment(Including guards against in front of smoke stair hall in view of various floors front room in front of room, fire elevator room, fire elevator with guards against which smoke stair hall to come in handy the front room) is has when the fire the personnel to disperse which saves goal with fire prevention, should report to the police the button first choice spot as the establishment manual fire. In addition, the room also should establish the manual fire to the common elevator in front of to report to the police the button.In the public active place (including hall, hall, dining room, multi-purpose hall and so on) and the main thoroughfare and so on place, the personnel very is all centralized, and mainly disperses the channel. Therefore should report to the police the button in these public active places main access establishment manual fires; The manual fire establishes which in the main thoroughfare reports to the police the button to guarantee "to a manual fire which most is close to reports to the police the button distance from a fire protection district any position not to be supposed to be bigger than 30 meters".3rd, the fire emergency broadcasts the speaker the establishmentThe aisle, the hall, the dining room and so on the public place personnel very are all centralized, and mainly disperses the channel. Therefore should press in these public places "to a recent speaker distance is not bigger than 25 meters from a fire protection district any spot" and "in the aisle last should not be bigger than 12.5 meters the speaker to the aisle terminal distance" the establishment fire emergency to broadcast the speaker; Next also should establish the fire in the public bathroom place emergency to broadcast the speaker.The first room (including guards against in front of smoke stair hall in front of room, fire elevator room, fire elevator with guards against which smoke stair hall to come in handy the front room) is has when the fire the personnel to disperse which saves goal with fire prevention, also has the fire door separation and the sounds of people is confused and noisy, therefore should establish the fire emergency to broadcast the speaker. In front of the common elevator the room also should establish the fire emergency to broadcast the speaker. Disperses the stair hall also is has when the fire the personnel to disperse which saves goal with the fire prevention, also the sounds of people are confused and noisy, therefore should establish the fire emergency to broadcast the speaker, by favors the fire emergency broadcast to disperse the instruction.4th, fire alarm installment establishmentThe establishment fire emergency broadcast fire auto-alarm system, the author thought also should install the fire alarm installment, but its control procedure should be: The alarm apparatus should confirm after the fire, uses manual or the automatic control mode unification to the fire correlation region transmission warning, stops the alarm apparatus work in the stipulation time, the rapid linkage fire emergency broadcast and broadcasts to the people disperses the instruction.The fire alarm installment establishment position, the author thought should report to the police the button position with the manual fire to be same, its wall surface installment should for be apart from the ground 1.8 meters highly5th, fire special use telephone establishmentInstalls the fire special use telephone extension telephone, should be located the engine room which related also some people is on duty frequently with the fire linkage control (including fire water plant, spare electricity generation engine room, matches substation, mainly ventilates with air conditioning engine room, discharges fume engine room, fire prevention elevator machine room and other), the fire fighting control system operates the equipment place or the control room, the fire duty officers observation room, the security manages spot and so on public room. Sedan of theater box the fire elevator and in the ordinary elevator all should suppose the special use telephone, requests the elevator machine room and the elevator sedan theater box, the elevator machine room and the fire control room, the elevator sedan theater box and the fire control room and so on three compositions is reliable to speaks the correspondence telephone system. Usually in fire control room; The establishment elevator monitoring demonstration plate (including position indicator, direction indicating lamp, to speaks correspondence telephone, trouble lamp and so on), in order to carries on the necessity to the elevator running status which in the surveillance and the emergency case controls.Is equipped with the manual fire to report to the police position and so on button, fire hydrant button also should install the fire special use telephone receptacle.Third, fire linkage control 1st, the fire linkage control should include the control fire pump to open, to stop, also should demonstrate opens pumps the button the position and the fire pump work and the malfunction. When the fire hydrant is equipped with the fire hydrant button, its electric installation work spot also should demonstrate the fire pump the working mode active status (namely establishment fire pump work indicating lamp). 2nd, the fire linkage control should include the control spraying of water and the water atomization fire fighting system opens, stops, also should demonstrate the fire pump the work and the malfunction and the fluent display, reports to the police the valve, the safety signal valve working mode active status. In addition, to the basin, the water tank water level also should carry on the demonstration monitor; In order to prevent the overhaul signal valve is shut down, the author thought should use the belt electric signal the control signal valve by to demonstrate it opens the condition. 3rd, the fire linkage control other controls and the demonstration function, should carry out the present national related standard and the standard specific stipulation.Fourth, fire auto-alarm system wiringIn order to prevent the fire occurs when the fire control, the correspondence and the warning line severance, causes the fire fighting work to be unable to carry on, creates the bigger economic loss; Also for the suppression electronmagetic interference (for example transformer, electric motor, electric cable and so on) the influence which produces to the fire auto-alarm system. The fire auto-alarm system transmission line and the fire control, the correspondence and the warning line should use the being flame-resistant electric cable, and should use the metal tube or the enclosed metal trunking protection. The fire manual positive governing installment line should use the fireproof electric cable, its electric cable also should use the metal tube or the enclosed metal trunking protection. Uses Ming Fushi, should takes the fire protection protective measures on the metal tube or the enclosed metal trunking.Fifth, concluding remarkThe author rests on the concrete project to implement the experience, elaborated the design basis, fire auto-alarm design actual problem and so on system equipment establishment, fire linkage control and its wiring pulls out some shallow opinions, its goal is enhances the fire auto-alarm system the design quality, discovered early and the notification fire, prevented and reduces the fire to harm, by protects the person and the property safety.随着我国经济发展快速发展,人民生活的水平不断提高,城市使用是每天着急,敦促建设面临着发展的方向。这种高层次的民间建筑维修所需的材料和方式也更加多样化加快,而且随着使用电力负荷和煤气消费量扩大,提议消防自动报警系统设计较高,更严格的要求。为了保证人民生命和财产的安全,消防自动报警系统的设计已经成为在高级别民间建筑设计的一个最重要的设计内容。目前的基础上撰文火灾自动报警系统设计监督工作的高层次的民间建设的经验,建议在目前国家相关标准和标准不清楚真正详细浅见解,为同事们的讨论,并指出错误。 首先,设计依据 火灾自动报警系统的设计是一家专业非常强的技术工作,同时还具有很强的政策性。因此,首先应明确以下设计依据: 第一,必须紧紧抓住的建筑设计防火标准,该系统的设计标准,标准的设备制造,安装施工审批标准和管理的法律和规章等五大方面的消防法律法规,并在实际了解国家有关本标准和标准积极字: “必须” , “必须假定” , “不适合” , “可能”和反面词: “严格禁止” , “不应该” , “没有” , “不适合“的含义。 第二,必须着眼于高层次的民间建筑的功能,利用和保护对象的防火等级,认真开展本标准和国家有关标准,认真对待公安防火监督部门的审批意见。 其次,火灾自动报警系统设备的建立 建立火灾探测器 要么全打开的印章或楼梯大厅应单独划分搜索范围,每个2 〜 3建立火灾探测器。 第一个房间(包括防前面的烟雾大厅楼梯前室,消防电梯间,消防电梯防前面房间烟雾楼梯大会堂来用场)和过道应区分单独划分搜索范围,特别是前面的房间,以及电梯,分散楼梯大厅和走道都是相互关联的,有时间的火灾烟雾比较容易收集或流动,是人员分散保存目标与防火,因此,应该安装火警探测器。关于共同电梯前室虽然不是人员分散,而且这方面的空间和良好的电梯是相互关联的,有时间的火灾烟雾也很容易被收集或流动,适当地划分为单独的搜索覆盖面和安装消防探测器。 电缆轴因此很容易形成掏出烟炎症渠道,拥有火灾时的火强度不容易延伸沿电缆燃烧,为此, “高级别民间建筑设计防火标准”和“民用建筑电气设计标准“分别提出了详细具体的规定,在建筑和在电线或电缆塑造。但认为具体实施的难度和目前的情况下,电缆竖井安装了火灾探测器是非常必要的,坐标轴的防火分隔要求,每2 〜 3或每一级安装。 电梯机房应安装火灾探测器,它的电梯是重要的垂直交通工具,其两个电梯机房已具有火灾危险性,其存在的三个基本解除以及打开洞,像打开闸门的水平之间的球洞,在气孔,持久的关系打开了洞与电梯机房或滑轮等,其时,有四个火,升降机以及往往成为火灾强度传播渠道,很容易危及电梯机房设施。因此,电梯机房建立了火灾探测器是必要的,也适用于皇冠建立火灾探测器举井。 2 ,手动火警报警按钮建立 (包括防前面的烟雾楼梯大厅鉴于各层前房间前面的房间,消防电梯间,消防电梯防这些烟雾楼梯大会堂派上用场前室)是有火灾时人员驱散节省目标,防火,应立即向警方举报的按钮,首选地点设立手动火警。此外,该室也应建立防火手册的共同电梯前,向警方报案的按钮。 在公共活动场所(包括会堂,礼堂,餐厅,多功能厅等)和主要通道等场所,是所有工作人员非常集中,主要是分散的渠道。因此,应立即向警方举报的按钮,在这些公共活动场所主要通道设立手册火灾;该手册规定的火灾中的主要通道报警按钮,以保证“ ,以手动火警最接近报警按钮距离防火区的任何位置不应该超过30米。 “ 第三,消防紧急广播喇叭建立 走道,大厅,餐厅等公共场所的工作人员都非常集中,主要是分散的渠道。因此,应该按这些公共场所的“最近的一项发言距离不超过25米的防火保护区的任何位置”和“在走道上不应大于十二点五米扬声器的过道末端距离”建立消防应急广播喇叭;下一步还应当建立消防在公共浴室的地方紧急广播喇叭。 第一个房间(包括防前面的烟雾大厅楼梯前室,消防电梯间,消防电梯防这些烟雾楼梯大会堂派上用场前室)是有火灾时的人员驱散节省目标与防火,也有分离和防火门的声音,人民的混乱和嘈杂,因此,应建立消防应急广播喇叭。在前面的共同电梯房也应建立消防应急广播喇叭。分散大厅楼梯也已经火灾时的人员驱散节省目标与防火,也是人民的声音和嘈杂的混淆,因此应建立消防应急广播喇叭,由主张消防紧急广播驱散指令。 第四,建立火灾报警装置 建立消防应急广播火灾自动报警系统,笔者认为还应该安装消防报警装置,但它的控制程序应该是:该报警器应确认火灾后,利用手动或自动控制模式统一消防相关区域传输预警,报警器停止工作时间的规定,迅速联系消防应急广播和电视节目,并且分散了人们的指示。 火警警报装置建立的立场,笔者认为应该向警方报案的按钮位置的手动火警是相同的,它的墙面安装应为距地面1.8米高度 第五,消防专用电话设立 安装消防专用电话分机电话,应设机房其中也涉及一些人是在工作地点经常与消防联动控制(包括消防给水设备,备件发电机房,火柴变电站,主要ventilates空调引擎室,排放烟气轮机室,防火电梯机房及其他) ,消防控制系统的经营场所或设备的控制室,消防责任人员观察室,现场的安全管理等公共空间。轿车的影院中消防电梯和普通电梯应假设所有使用的特殊电话,请电梯机房和电梯轿车影院中,电梯机房及消防控制室,电梯轿车影院方块和消防控制室等三个成分是可靠的讲通信电话系统。通常在消防控制室;建立电梯监测演示板(包括位置指示器,显示方向灯,以讲信函电话,麻烦灯等) ,以进行必要的电梯在运行状态的监视和紧急情况下的控制。 配备了手动火警报警位置等按钮,消火栓按钮,还应该安装消防专用电话插座。 第三,消防联动控制 第一,消防联动控制应包括控制消防泵开启,停止,也应表现出的按钮,打开泵的位置和消防泵的工作和故障。当消火栓设有消火栓按钮时,其电气安装工程现场也应表现出的消防泵的工作模式有效状态(即建立消防泵工作表明灯) 。 第二,消防联动控制应包括控制喷洒水和水雾化灭火系统打开,停止,也应表现出的消防泵的工作和故障和流利显示,报警阀,安全信号阀工作模式积极的地位。此外,该盆地,水箱水位也应进行示范监测;为了防止检修信号阀关闭,作者认为应该使用带电信号控制信号阀证明它打开条件。 第三,消防联动控制其他控制和示范作用,应进行本标准和国家有关标准的具体规定。 第四,火灾自动报警系统布线 为了防止火灾发生时,消防控制,通信和警戒线遣散,使灭火工作无法进行,造成了更大的经济损失,也为抑制electronmagetic干扰(例如变压器,电电机,电缆等)的影响而产生的火灾自动报警系统。火灾自动报警系统的输电线路和消防控制,通信和预警线应使用被阻燃电缆,并应使用金属管或封闭式金属线槽保护。消防手册积极理事分期付款行应使用防火电缆,其电缆也应使用金属管或封闭式金属线槽保护。使用明复,应采取防火保护措施的金属管或封闭金属trunking.Fifth ,结论备注 作者取决于具体的项目实施经验,阐述了设计依据,火灾自动报警设计和实际问题,以便建立系统设备,消防联动控制及其接线拿出一些肤浅的意见,其目的是增强了火灾自动报警系统的设计质量,早期发现,并通知消防,预防和减少火灾危害,通过保护个人和财产安全。
