基于WebService的智能电测仪器HMI实现

Realization of Intelligent Electrical Measuring Instrument HMI Based on WebService

为了实现电力测试仪器智能化需求,文章开发了基于嵌入式Linux的电测仪器人机交互界面人机接口系统。该系统通过移植Gsoap开源库,在其中实现了WebService服务器和客户端,取代了传统的上位机软件相关功能。系统采用3层软件结构,上层是基于Qt的图形交互界面,中间层封装业务模块,下层提供通用服务,并采用XML脚本进行配置管理。经实验证明,该系统可在不额外配备上位机管理软件的情况下,满足电测仪器行业的大部分交互需求,系统配置性、扩展性强。

In order to realize the intellectualization of electrical measuring instrument, the Human Machine Interface(HMI) system based on Embedded Linux is developed. By porting the GSOAP open source library, the HMI system realizes the WebService server and client, replacing the related functions of the traditional host computer software. The system adopts three-tier software structure, the upper layer is based on QT graphical interactive interface, the middle layer encapsulates business modules, the lower layer provides general services and it uses XML script for configuration management. Experiments show that the system can meet most of the interactive requirements of the electrical measuring instrument industry without additional management software of the host computer, and the system has strong configurability and expansibility.
