摘要
燃料开关的质量直接影响汽车的整体性能。给出一种适用于油/气双动力汽车电子燃料切换开关自动检测的测试系统的设计方案与电路实现。该测试系统基于单片机P89LPC938,由单片机查询测试人员从PC机发出的检测命令,并控制燃料开关进行相应功能的检测,测试完毕后将测试结果回送给PC机。测试系统与被测燃料开关之间的通信协议及通信接口是该系统提出的核心设计思想。该测试系统可以提高开关检测的效率及产品合格率。
The quality of fuel switch makes a direct impact on the performance of vehicle, this system introduces how to design and implement an automatic testing system with oil/gas dual - fuel power automotive electronics switch. The test system is based on single chip computer P89LPC938, testing PC- test command sent from the operator, controlling the corresponding testing of the fuel switch, sending the results back to the PC. It is the communication protocol and interface between the testing system and the fuel switch which are core design ideas. This test system can improve efficiency of detection and pass rate of fuel switch.
