摘要
设计了一种基于CAN总线的远程温度采集系统,主要由一个主监视器和多个温度采集点组成。通过CAN控制器SJA1000和驱动器82C250读取总线信号并向总线发送命令,将数字温度传感器采集到的温度信号,通过单总线传给STC89C52RC单片机,通过CAN控制器和驱动器将信号传至主监视器,使用LCD1602液晶显示器实现数据显示。
This article has designed one kind based on the CAN bus＇ s remote temperature gathering system,which is mainly composed by a primary monitor, and multiple-temperature gathering point. Completes reading of the bus signals as well as sending a command to the bus by the CAN controller SJA1000 and drive 82C250, the scene end through 18B20 digital temperature sensor gathering temperature signal, passes on through a single bus to STC89C52 RC microcontroller, then passes on through CAN controller and the driver to the main monitor, uses the LCD1602 liquid-crystal display to realize the data demonstration.
