| 摘 要： | 结合某电厂的电量负荷测量系统的实例，设计了一种基于DMP400仪表和RS485网络的分布式测量系统。详细介绍了在Delphi开发环境下开发串口通信程序，实现电量仪表数据实时采集的方法，整个程序采用了多线程技术，主线程负责操作分析，监视线程负责通过Win32 API函数进行串口通信；通信采用基于CRC校验的ModBUS协议。系统投入运行后，数据采集快速，运行稳定。该方法为同类系统的开发提供借鉴。

| Abstract: | Combining with an instance in power burthen measuring system of a power plant,designed a distributed measuring system based on DPM400 and RS485.It also introduced in detail the design method of real time power instrument data collecting by programming serial communication in Delphi.The multiple threads technology is used in this program,the main thread executes operating and analyzing,the monitoring thread executes serial communication by Win32 API function,which is based on Modbus protocol.The system is steadily and exactly after running.So this method can lead the way for the same kind system. |
