基于VC的多功能电力仪表上位机管理软件

为实现多功能电力仪表各项数据的实时检测，方便用户在一台主机上对多个下位机进行查看和管理，现开发出一款上位机管理软件。该软件基于MFC平台，利用MSCOMM通信控件，通过485总线与单片机进行通信。软件将采集到的数据处理整合，在一个界面上同时显示电压、电流、功率、电能等多项数据，数据自动厣j新。不同的下位机可选择显示，下位机的信号网络、电压变比、电流变比等参数可手动更改，软件同时还集成了电能值一键清零的功能。该软件使用简便，传送数据快速准确，现已投入市场运用。

PC Management Software For Multifunction Instrument Base On VC

In order to realize the real-time detection of Multifunction Instrument,we have researched and developed a upper computer software,which can make users check and manage down machine in one upper computer conveniently.This software based on MFC platform. It use MSCOMM and communicate with down machine via the 485 bus.The software disposal the collected data, then display various data such as voltage, current, power, energe in an interface.The data can refresh automatic. Users can select to display different down machine.And the parameter of down machine, such as input-net, pt-times, ct-times and so on, can be changed manually.The software also integrate one key clear energe function.This software is easy to use and it transmits data quickly and accurately.
