电力自动化装置插件的流水线自动测试系统设计

Design of Assembly Automatic Test System of Power Automation Device Plug-in

针对电力自动化装置插件种类多、数量大的现状,目前采用的半手工半自动测试方法测试效率低、准确度不高,提出一种流水线自动测试系统的设计方案。测试夹具和测试仪器之间通过高密度转接端子连接,仪器端口资源丰富,测试仪器端口在连接器上的布局不随测试对象变化而变化,只需要通过更换夹具来完成不同测试对象的测试工作,扩展性强,适用于多种类的插件功能性测试。完全自动化的线体部分,测试过程中不需要人为干预,基于LabVIEW的测试终端程序,实现与插件、PLC、测试仪器的交互,测试数据自动写入MES数据库,实现测试信息可追溯。实践证明系统可以高效地完成测试任务,准确定位故障,提高测试效率。

According to the large numbers of electric power automation device plug-in and that the present semi-automatic testing method is of low efficiency and low accuracy,a design scheme of pipeline automatic testing system was proposed.The test fixture is connected with the test instrument by a high-density connector.The instrument ports resources are abundant and the layout of the test instrument ports on the connector does not change with the test object.We just need to change the fixture to complete the testing of different test objects,strong expansibility and suitable for a variety of plug-in functional testing.The complete automatic testing process does not need human intervention.Based on the LabVIEW test terminal program,making the interaction with plug-ins,PLC and test instruments and the test data is automatically written into MES database to achieve the traceability of test information.The practice proves that the system can efficiently complete the test task,accurately locate the fault and improve the test efficiency.
