地铁广播系统板卡自动测试平台的设计

Design of Auto Test Platform for Subway Public Address Sytem

地铁列车广播系统普遍采用模块化设计,列车车厢内的广播系统机箱内有不同的功能模块。对这些模块的测试是个烦琐的过程。对此,设计一个自动测试平台,能够对这些模块进行自动测试,从而减轻测试人员的工作强度,提高测试效率,降低测试成本,同时能够提供给地铁运营方作为硬件维护的工作平台。

The subway public address system generally adopts modular design,and there are different functional modules in the public address system cabinet in the train compartment.Testing these modules is a cumbersome process.Therefore,an automatic test platform is designed to automatically test these modules,so as to reduce the work intensity of testers,improve test efficiency and reduce test cost.At the same time,it can be provided to the subway operator as a working platform for hardware maintenance.
