摘要
在自动化测量、数据实时采集和监控系统中,智能仪表之间、计算机和智能仪表之间的数据通信越来越重要。串行通信是主要的通信方式。结合工程实例,阐述了RS232/485串口通信原理,使用多线程技术实现了罐区的数据采集和传输系统。
It is very important to communicate between intelligent instruments and computers in the automatic measuring systems, real - time data acquisition and control system. Series - communication is the main method. Based on the engineering project, introduces the principle of RS232/485 series - communication, and realizes the data acquisition and control system by means of multithreading technology.
