Test board, detection system and method for detecting peripheral interface of industrial system

The invention relates to the technical field of board card interface detection, and particularly discloses a test board, a detection system and a method for industrial system peripheral interface detection, the test board comprises a mother board and a daughter board, the daughter board is used for receiving and processing a signal from the mother board and judging whether a to-be-tested board card interface is normal or not, and if yes, the to-be-tested board card interface is detected. And/or is used for simulating an input signal and transmitting the input signal to the mother board; the mother board is used for transmitting the input signal to a board card to be tested to detect an input type interface of the board card to be tested, and/or is used for transmitting a signal from the board card to be tested to the daughter board to detect an output type interface or a communication interface of the board card to be tested. According to the scheme, the daughter board of the test board is matched with the mo
