摘要
介绍分布式测温系统的具体实现方法,以C8051Fxxx单片机为基础,通过DS18B20温度传感器获取温度,温度值通过RS485与主机进行通讯。介绍该系统的硬件实现方案、数据传输协议、通用I/O端口及软件实现RS485数据收发的原理和DS18B20的应用。
This article introduces the implement method of distributed system in details, get temperature by thermometer DS18B20 based on C8051Fxxx siglechip. The temperature transmits to host computer by RS485; In the article we illuminate the hardware realization scheme of system, protocol of data transmit, I/O port and element of RS485 realizated by software, application of DS18B20.
