摘　　要：针对飞机制造企业在对数量巨大的电缆进行检测时,由于频繁转接芯线耗时耗力而影响生产效率的问题,设计了一种采用行列矩阵布置的程控矩阵开关;通过程序控制任意芯线的自动选通,具有批量处理和测试点扩展的能力,能够实现矩阵开关完整性的自检功能;设计完成后,利用该系统进行实验,测试数据的误差基本控制在0.4%以内,而且测试速度快,特别适合需要频繁选通芯线的电缆自动测试系统。A plenty of cables need to be tested in aircraft manufacturing enterprises,joining cables frequently has been proved to be a work with low efficiency.A program controlled matrix switch is designed.Based on matrix form,any wire of the cable can be conducted automatically according to the program in principal computer.Batch processing,extension and self-inspection are realized.After system was built,a test was done.And test result shows this matrix switch＇ s maximum error is 0.4％,and the test speed is fast,so it is particu larly suitable for automatic test system which need join cable frequently.
