仓库多点温度监控系统设计 ——硬件系统设计 中文摘要：随着当今社会的不断进步和工业技术的迅速发展，人们越来越重视温度因素，许多产品对温度范围要求严格，而目前市场上普遍存在的温度检测仪器大都是单点测量，同时有温度信息传递不及时、精度不够的缺点，不利于工业控制者根据温度变化及时做出决定。在这样的形势下，开发一种能够同时测量多点，并且实时性高、精度高，能够综合处理多点温度信息的测量系统就很有必要。 本系统是通过AT89C51单片机来实现对粮仓的多个点温度进行温度的测量和控制。在设计中51单片机相当于是整个系统的心脏，DS18B20温度传感器将采集的温度模拟信号直接转换成9位的数字信号，再传送给单片机。单片机对接受的信号进行相应的分析并做出一定的应对响应，从而达到温度的检测与控制。通过以上的分析，我们知道在本系统中大概包括以下几部分：温度检测模块、显示模块、温度调节模块、超温报警模块以及保证单片机正常工作的时钟电路及复位电路。 关键词：温度；AT89C51单片机；报警；复位 Abstract：With the rapid development of society and industrial technology, people pay more and more attention to the temperature factor, many products are strictly required with the temperature ranging and temperature measuring instrument.The currently prevailing in the market are mostly single-point measurement, at the same time, there is not enough accurate temperature information transfer which is not conducive to industrial control according to the temperature changes in a timely decision. In this situation, in addition to the development of a multi-point measurement, and real-time, the measurement system can control the temperature information is necessary. This system achieves the measurement of multiple point temperature of the granary through the AT89C51 singlechip. In the design of the 51 single chip microcomputer is equal to the heart of the whole system, DS18B20 temperature sensor to collect temperature direct conversion of an analog signal to digital signal 9, and then transmitted to the single-chip computer. MCU analyzes the received signal and make certain coping response, so as to achieve the detection and control of temperature. Through the above analysis, we know that in this system probably includes the following parts: temperature detection module, temperature display module, temperature control module, temperature alarm module and the assurance of clock circuit and reset circuit microcontroller work.
