Abstract

The invention provides a circuit board testing device and method. The circuit board testing device comprises a controller, a testing board, a conduction connection circuit, a host computer, and a power conversion circuit, wherein the controller receives a testing instruction sent by the host computer and controlling the testing board and / or the conduction connection circuit to test the connected tested circuit board according to the testing instruction; the conduction connection circuit is used for enabling the tested circuit board to form a communication loop; the testing board is used for controlling a testing circuit connected with the tested circuit board to work to realize test on the tested circuit board; the controller acquires electric signals generated by the tested circuit board;and the host computer judges whether the tested circuit board is normal according to the electric signals acquired by the controller. The whole testing process is completed automatically, manual testing is not needed, and the manual cost during the testing process is further reduced; and besides, testing result errors caused by human errors do not exist in the automatic testing process, and the testing accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of circuit testing, and in particular relates to a circuit board testing device and method. Background technique [0002] Printed circuit board (PCB), also known as circuit board, is used in almost every electronic device. It can be seen that the function of the circuit board will directly affect the function of the entire electronic device. Therefore, the testing of circuit boards is particularly important. [0003] In practical applications, many circuit boards with different functions may be involved. For example, the automatic train protection subsystem (Automatic Train Protection, ATP) system includes nearly ten kinds of interface boards, and the interface boards usually serve the function of signal transmission. Many test items of the interface board testing device in the related art are manually tested, and automatic testing cannot be realized, and the operation is complicated and the labor cost is h...
