在分布式电力监控系统中,为实现现场数据采集装置与监控中心计算机的通信,完成对工业现场电参数的实时采集与监控,采用基于Modbus规约的智能模块EDA9033D作为现场数据采集装置,利用用VB6.0中的MSComm串口通信控件作为现场数据采集装置与监控中心计算机的通信软件,来开发电量采集监控系统。系统实现了同时、快速、连续采集多个不同的电参数,既降低了硬件成本,又增强了软件开发的灵活性和通用性。
In the distributed power monitoring system, in order to realize the communication between the on-site data acquisition device and the monitoring center computer, the real-time acquisition and monitoring of the electrical parameters of the industrial site are completed. The EDA9033D intelligent module based on Modbus protocol is used as on-site data acquisition device, .0 in the MSComm serial communication controls as field data acquisition and monitoring center computer communication software to develop power monitoring system. The system realizes the simultaneous, rapid and continuous acquisition of a number of different electrical parameters, which not only reduces the hardware cost but also enhances the flexibility and versatility of software development.
