The relay protection tester 102 adjusts X, Y two-phase output current values according to the excitation configuration instruction issued by the front-end processor 106, slowly increases two paths of alternating currents from 0mA to 130mA simultaneously, and simulates two fans to work. In the whole test process, if an experimenter observes that the high potential is 24V between the pins X7(1 and 3) of the safety and fan control detection board 111 on the human-computer interaction interface, the experimenter indicates that the fan normal state detection function of the safety and fan control detection board 111 is normal. Then, the phase X current output by the relay protection tester 102 is reduced to 0mA, and a fan operation abnormality is simulated, and if a low potential of 0V is detected between the pins X7(1, 3) of the safety and fan control detection board 111 at this time, it indicates that the fan abnormal state detection function of the safety and fan control detection board 111 is normal. Then, the X-phase current output by the relay protection tester 102 is increased to 130mA, and it is detected that the voltage between the pins X7(1, 3) of the fuse and fan control detection board 111 is at the high voltage level of 24V. Similarly, the Y-phase current outputted from the relay protection tester 102 is changed from 130mA to 0mA and then returned to 130mA, and the fan abnormal state detection function of the fuse and fan control detection board 111 is tested again.
