摘要
此系统用于基于485总线的分布式局域网实时监测系统,利用485总线抗干扰能力强,可用于分布较广、距离较远的监测任务。用VC编制了主机端的监控程序和处理程序,利用主机的程序对下位机(单片机)进行设置,数据的读取、处理。实现对所有监测点的全局控制。同时,使用了数据库技术,使接收数据后的显示、处理和存储更为方便和高效。
This system,which is based on the 485 bus, realizes the real- time local network distributing system. The 485 bus has strong anti - noise capabilities. It can be used for the monitoring mission, which is distributed. In this project the monitoring and processing program with VC by the side of the host PC. The host can set the slave,read data from slave, process the read data and control all the monitoring position. The database technology is also used, the display, processing and memory are convenient after receiving data.
