Abstract
A door lock system having state feedback comprises a door lock; a control circuit for controlling the unlocking or locking of the door lock; a feedback circuit for detecting the state of the door lock; a central processing unit for reading the state of the door lock outputted from the feedback circuit and controlling the control circuit to unlock or lock the door lock. In the door lock system, the electromagnetic valve is used instead of mechanical switch, which lowers the failure rate of the door lock and improves the reliability of the door lock, and the feedback circuit is capable of detecting the state of door lock, and therefore a feedback signal can be provided in time when the door lock is failed, which ensures the efficient control of the door lock.
