基于USB的飞机防滑刹车控制器测试系统设计

Design of USB-based Test System of Skid-proof Braking Controller for Aircraft

飞机防滑刹车控制器是飞机制动系统的核心部件,其的测试系统主要完成飞机刹车控制器的离线检测。通过模拟飞机刹车过程中的各种物理量,对控制器的功能进行检测,并通过USB接口将测试结果上传至后台便携式计算机。重点介绍了飞机防滑刹车控制器测试系统的原理以及软硬件实现过程中USB接口芯片CH375的使用,并利用VC++软件开发平台实现对飞机刹车控制器测试数据的接收、处理和显示,为控制器提供了一套有效的检测手段。

The skid-proof braking controller is the core part for braking system for aircraft. The test system of controller mainly completes offline detection of aircraft braking controller. Through simulating various physical variables in braking process, the functions of controller are detected and the test results are uploaded to background portable computer through USB interface. The principle of the test system of skid-proof braking system controller, the use of USB interface chip CH375 in hardware and software implementation is introduced emphatically. By adopting VC＋ ＋ software development platform, the test data are received, processed and displayed ; a set of valid means of controller examination is provided.
