单片机的发展历史英文论文题目

我也是做流水灯的毕业论文,英文部分太难找了,给个建议吧

Since the introduction of computer-chip technology in society, in every field in a wide range of light control systems, the microcontroller is replaced by the gear regulating the delay time of old growth rate in future in the heart of this to the MCU has several benefits: small size, light weight, a single power supply; features, low power consumption and low; and the data transfer, one finds in SCM internal, run fast, uding, high reliability, so single-chip is widely used in measurement and control system, data acquisition, instrumental, Mechatronics product, smart interface, computer communications, as well as single-chip multilevel system, article is primarily deals with a subject name is single-chip-chip, flowing water and light control, which enables we learned how to use the SCM control our lives in the application of the design of this subject at a later time, introduced me to many aspects of the topic describes in detail by the MCS-89C51 manifold programming the control circuit, it completed the single-chip flowing water and light control features, and gives specific hardware circuits and the appropriate kind of control circuit reliability, flexibility, use the wide-ranging especially suitable for medium-sized cities of traffic lights, neon lights, , it on other similar system has certain significance.

近年来随着工业的发展，人们对过程控制的精密度和可靠性提出了更多更高的要求，因而液位控制也向着功能齐全，控制灵活，操作简单，控制精度准确的方向发展。液位调节器是生产中应用很广液位测量和控制的设备，所以测量的精确性和控制的准确性是本设备的关键。在研究国内现有传统的液位调节器的基础上，设计的了采用AT89C51单片机为核心，A/D转换器采用ADC0809、D/A转换器采用DAC0832、键盘显示芯片采用74LS165、74LS164。外部数据存储器采用PCF8583；硬件电路包括：温度检测电路、A/D转换电路、D/A转换电路、键盘显示电路、V/I转换电路、电源电路，由这些构成一个单片机液位调节系统。软件包括PID控制算法、液位控制。本系统把单片机应用于液位测量控制中，既提高了产品的功能和质量，又降低了成本。本系统还具有结构先进合理、功能完善、满足控制精度的要求、抗干扰能力强、较高的灵活性和可靠性、通用性好、价格低，使用方便等特点。Withindustrialdevelopmentinrecentyears,processcontrolforprecisionandreliabilityofmorehigherrequirements,andalsotowardtheliquidlevelcontrolfunctions,controlofaflexible,simpleoperation,.
