铁路信号机械室环境温度监测下位机设计

介绍一种基于Atmel 89S51单片机的环境温度监测下位机的设计,解决对铁路信号机械室内重要设备卫作温度的监测问题.环境温度测量使用DS18B20单总线数字温度传感器.与上位机以主从通信方式实现串口通信,实时向主机发送环境温度信息.

Design on Environment Temperature Inspecting and Measuring System for railway signal and machine room

It was introduced a kind of system designing method which was used for environment temperature inspecting and measming. This System could be used for inspecting and measuring the working temperature of important devices which was placed in the railway signal and machine room. It was chose a temperature sensor that the type was DS 18B20 for environment temperature measuring. The System could communicate with controlling host computer for transmitting the temperature information. As for the communication mode was concerned, it was chose the principal and subordinate way to implemente serial communication.
