Before the control module controls the driving part to operate according to the set locking control instruction and/or unlocking control instruction, the reset recording part is required to detect whether the driving part/door driving mechanism is at a starting initial position; the locking or unlocking operation is carried out under the reset condition, so that the control accuracy is ensured; if not, the battery replacement operation is prompted, the initialization step is carried out before the power is re-powered on, and then the reset step is carried out.
In the power exchange operation, after the power supply part is replaced, as shown in fig. 8, similarly, the type that the door lock is unlocked in the reverse rotation mode and locked in the forward rotation mode is still used for explanation, and the type that the door lock is unlocked in the forward rotation mode and locked in the reverse rotation mode can be changed only in the rotation direction of the motor;
the method comprises the steps of firstly carrying out an initialization step, judging whether a photoelectric identification piece is 0, if so, stopping for 1s after the motor rotates for 0.03s in a delayed mode, positively rotating and locking the motor by the step number X, judging whether a second identification piece is 1, if not, prompting system abnormity, if so, stopping for 0.1s, reversely rotating the motor, judging whether the photoelectric identification piece is 0, if so, stopping after the motor rotates for 0.03s in a delayed mode, finishing battery replacement, and detecting whether the performance of a door lock driver is complete after the battery replacement, thereby improving the safety.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiment, and any technical means that can achieve the object of the present invention by basically the same means is within the scope of the present invention.
