        摘 要:分析了路內(nèi)測(cè)試及總線測(cè)試的基本原理,提出了電控組件 PCB 板檢測(cè)系統(tǒng)的軟硬件設(shè)計(jì)方案。該系統(tǒng)采用研華工控機(jī)作為上位機(jī),通過(guò) PCI 輸入輸出板卡連接控制器控制開(kāi)關(guān)矩陣,對(duì)待測(cè)電路板加載測(cè)量信號(hào),并實(shí)時(shí)采集輸出信號(hào),通過(guò)接收到的輸出信號(hào)判斷 PCB 板是否工作正常,同時(shí)還可生成檢測(cè)報(bào)表。檢測(cè)試驗(yàn)證明,該系統(tǒng)可以自動(dòng)對(duì)電控組件 PCB 板的功能進(jìn)行檢測(cè),檢測(cè)結(jié)果準(zhǔn)確,且能提供故障提示信息。

        Abstract: This paper analyzes the basic principle of in-circuit test and bus test, and puts forward the software and hardware design scheme of PCB board detection system for electronic control components. An Advantech industrial control computer is used as the upper computer in the system, which connects the control switch matrix through PCI input and output board card. While loading measuring signals on the circuit board to be tested, the output signals are collected in real time. Through the received output signals, it can be judged whether the PCB board is working normally. In addition, the system is capable of generating the detection report. Practice has proved that the system can automatically detect the function of the electronic control component PCB board, and the detection results are accurate. In addition, it can provide fault prompt information.
        Key words: PCB board test; in-circuit test; bus test; detection report
