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
