基于多通信模式的分布式测控系统设计与应用

Design and Application of Distributed Measurement and Control System Based on Multi-Communication Mode

基于车辆新型供电体制测试需要的目的,综合虚拟仪器技术和多种通信网络技术,构建了一个包含多种通信模式的分布式测控系统;并采用虚拟仪器软件LabWindows/CVI,借助串行通信技术和以太网络技术,编制应用程序;实现各子测控系统数据采集、初步分析和控制指令发布的功能;完成各子测控系统与远程监控终端的数据传递,使远程监控终端对整个系统运行的情况进行直观的实时图形化显示,并能对整体的实验数据进行统计、分析和实验结果的输出。

Based on the requirement of testing the new Power-Supply system of vehicle, it constructs a Distributed Measurement and Control System containing multi-Communication Mode using Virtual Instrument technology and several kinds of Communication technolo- gy. With the support from Serial Communication technology and Ethernet, it used LabWindows/ CVI to design the application program, which can realize such functions of the Measurement and Control Subsystems as data acquistion, analysis and command sending, and which also can realize the between the Remote Terminal and the other Subsystems so that the Remote Terminal not only can exhibit the Real--time Graphical Display of the whole system operation, but also can calculate and analyze experimental data as well as export the experimental resuits.
