As shown in fig. 1, the interface circuit performs input sampling on the state of the signal input mechanism, and writes the sampled result into the data register for storage. In one scanning period, the microcomputer controller reads data from the register, performs program logic operation and provides output information to the output interface circuit according to the operation result. And repeating the steps, and performing cyclic scanning.
As shown in fig. 2 and 3, the specific principle process is as follows: when the commercial power is normal, the electric brake release device detects that the commercial power is normal, the state of the button is monitored, if the button is found to have a closing fault, the electric brake release device immediately reports the fault, and meanwhile, the fault indicator lamp is lightened. Pressing the button, the device does not output; if the button is detected to be in a normal state, the electric brake release device jumps to a charging mode, and a charging indicator lamp is lightened.
When the commercial power is powered off and before the commercial power is powered off, the electric brake release device monitors the closing fault of the button, the device reports the fault, the fault state is maintained, the button is pressed, and the electric brake release device does not output. After the commercial power is cut off, the electric brake release device scans and checks the state of the button before starting output, monitors the closing fault of the button, protects the device from fault, presses the button and does not output. After the mains supply is powered off, no button closing fault is monitored, and after the scanning inspection is passed, the starting button and the public button are pressed simultaneously, so that the device can output voltage. During the output voltage of the device, the device turns off the output by releasing the button. Before restarting the output, the device scans the state of the check button again, and only after the output condition is met, the device can output voltage again. Otherwise, the device reports the fault, keeps the fault state and does not output.

Before restarting the output, the device scans the state of the check button again, and only after the output condition is met, the device can output voltage again. Otherwise, the device reports the fault, keeps the fault state and does not output.
