Design and Implementation of The Automated Test Systems about Online Monitoring System Based on Embedded Linux for Tilt of Power Transmission Line Tower

摘要:

在总结实际工作经验的基础上,针对在测试输电线路杆塔倾斜度在线监测系统过程中存在的搭建测试环境复杂、测试步骤繁琐、测试周期长、测试效率低、测试结果格式混乱等问题,设计了一个使用客户端/服务器架构的自动化测试系统,详细论述了该系统的设计方案和实现原理；客户端基于嵌入式linux系统,采用多线程技术,通过以太网,使用定制的通信协议与服务端通信,能够在收到服务端指令后自动完成输电线路杆塔倾斜度在线监测系统硬件模块的功能测试；服务端采用python和PyQt开发,能够跨平台运行,使用多线程技术,实现了图形化控制客户端、查看客户端测试状态、保存测试日志、生成标准化的xls和pdf格式的测试报告等功能；实际应用表明,该系统有效可靠结果准确,提高了测试效率,提升了输电线路杆塔倾斜度在线监测系统的可靠性。

Abstract:

An automated test system of C/S architecture which is based on the practical experience regarding of the feedback from the production & test department is proposed in order to solve the issues of building test environment complexly、long test cycles、low efficiency of testing、chaotic test formats and so on. The architecture and the implementation are discussed in detail.The client that based on embedded linux uses multi-threading technology, can communicate with the server through customized protocol via ethernet and automatically test the hardware that composed of the online monitoring system of transmission line tower tilt. The server that is coded in python and PyQt can operate on cross-platform,check the status of the test procedure,save test logs,export the test report of xls and pdf format and so on through GUI。Engineering practice verifies the automated test system is effective in practice.
