摘要
介绍了以AT89LV51单片机为核心的温度控制系统的工作原理和设计方法。控制系统由上位机(PC机)和分机组成,分机负责一个粮库的温度监控任务,分机与主控机的通信采用无线通讯方式,温度信号由数字温度传感器DS18B20采集,并以数字信号的方式传送给单片机,然后将温度信息由无线通信模块PTR8000发送给上位机。
It also introduce the working theory and design method of the temperature system,which working core is AT89C51 SCM. Control system is made up by PC computer and extension computer,the extension respond for monitoring temperature of single depot,the communication method is wireless between main and extension computer, digital temperature sensor DS18B20 collects the temperature signal and transmit the digital signal to SCM,and then the temperature data should be transmit to PC computer by witless communication module PTR8000. Wireless communication can make the CRC verify and special coding for transmitting data,which enchance the reliability of data transmission.
