摘　　要：针对实验现场监测的特点,引入先进的现场总线技术,发挥计算机可靠的控制能力,给出了自主开发基于CAN总线的环境温湿度测量装置实现方法。该系统基于CAN总线,采用PIC18F458单片机作为控制器,并通过RS232串口实现上下位机通信。软件设计采用模块化程序设计方法,包括CAN总线通讯、现场温湿度采集、LCD显示模块等。系统运行稳定、可靠、操作简便。An advanced field bus technology is introduced according to the characteristics of experimental site moni- toring to improve computer＇s control ability. A self-developed temperature and humidity measuement device based on CAN bus is elaborated. The system takes the PIC18F458 microcontroller as controller, The communication between master and slave computersthrough RS 232 is realized. The modularized program design method is adopted in software design. It includs the CAN bus communication, site temperature and humidity＇s collection, LCD display modules and so on. The system runs stably and reliably, and is easy to operate.
