基于LabWindows/CVI的汽车继电器追溯系统设计

Design of Vehicle Relay Traceability System Based on LabWindows/CVI

在汽车继电器的测试过程中,对产品的实时数据采集和测试工位的监控对产品后期的追溯具有重要意义。在LabWindows/CVI的开发环境下,设计汽车继电器追溯系统程序,通过DLL接口调用的形式,实现生产参数配置并下载、上传测试数据、工站错误报警、登录人员权限管理、测试数据查询等实时追溯功能。实验测试了追溯系统的数据查询功能,对参数配置下载、数据上传和查询时间进行了统计和分析。结果表明,该追溯系统具有良好的稳定性和实时性。

In the test process of automotive relays,the real-time data acquisition of the product and the monitoring of the test station are great significance for the later traceability of the product.In the development environment of LabWindows/CVI,this paper designs the automotive relay traceability system program,and realizes the production parameter configuration and download,upload test data,station error alarm,login personnel authority management,tests data query and other real-time trace through the form of DLL interface call.
