基于89C51的线束检测系统设计

目前检测线束质量的手段相当落后,仅靠万用表、蜂鸣器或指示灯用手工逐点搭接,观察有否电、声或光信号来判断线束通断,这样效率低,还易造成错检或漏检。本文中设计的线束检测系统,由单片机控制多路电子开关进行数据采集,计算机分析,来判断线束质量,功能强大,界面友好。整套线束检测不到5 s,提高了效率,采用智能分析,无错误现象发生。且整套系统成本不到国外线束检测设备的十分之一,可以在线束厂家广泛应用。

Design of wiring harness tester based on 89C51

Now many methods of wiring harness testing are inefficient that still only depending on the multimeter,the buzzer or the indicating lamp to judge make-and-break,which lead to the wrong examines or the omission easily.In this paper,a new design of wiring harness testing system is discussed.Through the multi-channel electronic switching controlled by the single chip microcomputer,data is collected and analyzed by computer.enhance the efficiency,the intelligent analysis reduce wrong examines,and testing the entire system only costs 5 seconds and 1/10 capital compared with the foreign testers.
