气体检测论文翻译

试着翻译如下，参考： In accordance to the coming of "Information Era", sensor technology has increasingly progressed, and its coverage is more and more extensive,meanwhile, the demand for it is also becoming more urgent and monitoring system for indoor hazardous gas we are designing now is in purpose of pre-detecting and alarming of any harmful gas indoors,thus help prevent and reduce risk aiming at protecting security of human health as well as article is based on the core technology of resistor-based air sensor and TMS320F2812 DSP, it fulfills the function to display the gas density and enable communication of the upper serial ports, makes the significant exploration and study on the operating technology of alarming for hazardous gas, and holds a referring value in the area of monitoring implementation.

With the diversity of social and economic development, buildings, structures, Applied Materials, the development of various industrial and science and technology, increase in combustible materials, coupled with people's living environment and lifestyle changes, the risk of fire is increasing, the number of firescasualties and economic losses caused by fire is gradually increasing. Fire as the enemy of endangering the survival of mankind, more attention has been paid. With the growing number of high-rise buildings, fire hazards increase. Event of fire, will people's lives and property caused great harm, so people began to seek a method of early detection of fire, in order to control and extinguish fires and to minimize losses, protect life the development of electronic science and technology, electronics technology has become a powerful means of security, many security aspects of electronic products, the right-hand man of the people's lives. This design uses a microcontroller technology with A / D conversion chip to build a combustible gas detector alarm. When the leak of flammable or toxic gases in the environment to the critical point of the combustible gas concentration reaches the alarm set, when the gas alarm detection, combustible gas alarm will send alarm signal to remind staff to take safety measures. This paper briefly describes the design combustible gas detection alarm as well as the advantages of the SCM system; then details the design flow of the combustible gas detection alarm, as well as hardware and software systems design and software programming detailed steps, including the various modules of the program design and system debugging and simulation steps, design uses the MQ-2 gas sensor signal acquisition tool as a combustible gas, the collected analog voltage after the ADC0809 converted into digital signals. Single-chip digital signal acquisition to the ADC0809 has been calculated, if the combustible gas concentration reaches the critical point when the alarm is set microcontroller will drive the LED and buzzer alarm signal. In the case of non-combustible gases, the occurrence of unknown danger, the alarm can artificially control buttons to change the fire alarm initial value. 希望能帮到你

推荐楼主用机译,因为这个文章实在很长.
