Abstract
The invention relates to a hardware test equipment circuit of the transducer driver board, which comprises a transducer driver board, a signal processing control module and a display module. The signal processing control module connects nine analog in the transducer driver board to nine analog channels of the signal processing control module via the test needle. The signal processing control module outputs six PWM signals for controlling the communication of the high-speed optocoupler and detects if the optocoupler is communicated via the signal processing control module. The signal processingcontrol module outputs the signal to control the driving of the fans, the relay and the contactor and detects the driving working status of the fans, the relay and the contactor. The signal processing control module connects the braking test signal, the locked-rotor signal of the fan, the short circuit signal and the fuse signal in the driver board. The signal processing control module is connected to the display module. The hardware test of the driver board realizes the automation, the test result does not be influenced by humanity, thereby promoting the production efficiency and the test accuracy.
