At this time, the main bluetooth module 30 cuts off the connection between the ground of the motor driving chip U600 and the reference ground by controlling the N-MOS transistor Q600, so that the positive electrode and the negative electrode of the output end of the U600 driving chip are not connected with the reference ground, and then the bluetooth main control chip U800 notifies the slave bluetooth module 40 to control the unlocking of the driving motor of the slave motor driving chip U601, thereby ensuring that the 2-way motor driving chip can be normally unlocked when one way of damage occurs.
