Abstract

The present invention provides a kind of CPCI bus test device and method, relate to the technical field of automatic test of data transmission bus, comprising: test result display, logic controller, CPCI motherboard connection assembly to be tested, CPCI signal distribution router, standard PCI network card controller and ATX power supply. The logic controller is connected to the ATX power supply, the standard PCI network card controller and the CPCI signal distribution router respectively. The connection component is connected with the standard PCI network card controller, the connection component of the CPCI motherboard to be tested includes a 25p connector and a 22p connector, and the test result display is connected with the logic controller. The technical solution realizes the automated testing of the CPCI main board, improves the efficiency of the CPCI main board test, reduces the labor cost of the CPCI main board test, and alleviates the technical problems of low bus detection efficiency and high labor cost of the existing CPCI main board.

Description

technical field [0001] The invention relates to the technical field of data transmission bus automation testing, in particular to a CPCI bus testing device and method. Background technique [0002] At present, all 6U CPCI motherboards contain CPCI bus functions, and support CPCI specifications, and the anti-vibration impact capability and reliable heat dissipation capability are enhanced, but the efficiency of testing the CPCI bus is low, especially in the case of mass production of motherboards with CPCI bus functions. The testers bring a lot of pressure, and the labor intensity is too high. The traditional test of the 6U CPCI bus function is to install 7 standard peripheral boards on the standard 6U CPCI backplane, and at the same time insert the tested CPCI main board into the main slot, and connect the monitor, keyboard and mouse to the main board. Then install the ATX power supply on the backboard, manually power on the tested CPCI motherboard, wait for the motherboard...
