基于C#的交流异步电机测试与分析系统开发

Development of Test and Analysis System of AC Asynchronous Motor Based on C#

针对电机出厂前需进行测试分析这一情况,以西门子S7-1200为控制器,基于Visual Studio平台,采用C#高级语言开发了一套交流异步电机测试与分析系统;首先,设计了包括监控层、测控层、设备层的系统总体结构;其次,给出了西门子S7-1200PLC与上位机的以太网通讯,及与匝间耐压测试仪、电参数测试仪、转矩测试仪等仪表之间的RS485通讯实现方法;然后,根据国标GB/T1032-2012开发了系统,分析了系统功能和数据库设计方法;最后,系统应用于某电机生产企业,通过现场测试实例表明,系统实现了电机在不同状态下的数据采集、显示、存储和分析,并形成了试验报告,帮助企业提高了生产效率和试验精度。

Motor need to be tested before out of the factory. According to this situation, Siemens S7--1200 as the controller, a set of test and analysis system of AC asynchronous motor are developed based on Visual Studio and C#. Firstly, this paper introduces the general structure of the system, including monitoring layer, measurement and control layer and equipment layer. Secondly, it introduces the Ether- net communication between Siemens S7-1200 PLC and PC and the concrete implemention ways of RS485 communication between Siemens S7 -1200 PLC and interturn withstand voltage tester, electric parameter tester , the torque tester and so on. Then according to national standard GB/1032-2012, the system are developed and it gives the fuction of the system and designed means of database. Finally, the sys- tem is applied to a motor manufacturing enterprises. The examples of test on spot show that the system realizes acquisition, display, stor- age and analysis of the data in the different state of motor. Also it forms the test report and help enterprises improve the production efficiency and test accuracy.
