电动汽车能量管理单元电路板自动测试系统
资料介绍
针对电动汽车能量管理单元其电路板测试繁杂的问题, 研究设计一种自动测试系统.采用Fresmle MC9S12 系列MCU 作为主控芯片, 通过CAN 总线实现上位机、下位机、被测板之间的数据传输.系统实现了对能量管理单元4 种板件及整机的6 类不同测试.上位机软件可对测试项目进行高度灵活地配置, 实时显示测试结果,保存至数据库, 并生成Word 报表.经前期测试,对于同一种板件的全功能测试可在1min 内完成, 单个通道的绝对误差可小于0.05V , 并且其故障检出率可达到100% .
To solve the problem of Energy Management Unit( EMU) of electric vehicles,we develop an automatic test system. MCU of Frescale MC9S12 series is used as master chip. Upper computer,lower computer and unit to be tested are connected with CAN. 6 different tests of unit and its 4 types of PCBA can be tested by automatic test system. The test items can be configured highly flexible. Upper computer software shows the test results in real time,saves the data to the database and creates the Word table. After the early testing,all tests of one kind of PCBA can be finished in 1 minute. The absolute error of the automatic test system is less than 0. 05 V,and its fault detection rate is 100%.
