And after receiving the identity information sent by the identification terminal, the server stores the identity information, matches the identity information with the identity information prestored in the server, if the matching is successful, the server sends an unlocking signal to the control circuit module, and acquires and stores the current time as unlocking time while sending the unlocking signal.
After receiving the unlocking signal, the control circuit module controls the hollow rotating motor 8 to start to drive the screw rod 3 to rotate anticlockwise, and the screw rod 3 is enabled to move towards the first lock body 1 through the threaded fit of the screw rod 3 and the rotating support part 6 until the screw rod 3 is completely separated from the hollow inner rotor, so that unlocking is completed; after the unlocking is finished, the control circuit module controls the force sensor 11 to start, and whether a subsequent cabinet door is closed or not is detected.
The utility model discloses a be connected the control circuit module in the automatic vending machine with the locking mechanical system and the release mechanism of electronic lock, realize locking the automation control with the unblock. Through setting up the detecting element who is used for detecting the cabinet door and closes, automatic locking when realizing that the cabinet door is closed prevents to forget the potential safety hazard that locks and cause because of operating personnel. Through setting up the server, discernment terminal and discernment bar code, pass through wireless network connection with control circuit module in server and the automatic vending machine to make operating personnel can carry out automatic unblock operation to the electronic lock through discernment terminal scanning discernment bar code, need not to set up special person of unblanking, improved operating personnel's work efficiency, reduced the maintenance cost of automatic vending machine, can prevent simultaneously that the person of unblanking from losing because of the key and producing the potential safety hazard. The server stores the current locking and unlocking time and the received identity information when sending the locking signal and the unlocking signal, so that the identity information of the operator and the unlocking and locking operation time of the operator can be recorded, and the subsequent managers can conveniently manage the goods safety and maintenance condition of the automatic vending machine according to the recorded identity information and operation time. The first driving motor 5 and the hollow rotating motor 8 are arranged to respectively control the screw rod 3 to rotate clockwise or anticlockwise for locking or unlocking operation, so that the problem that the driving motor fails to lock or unlock due to the error of the rotating direction caused by the failure when the screw rod 3 is driven to rotate forwards or overturns by one bidirectional driving motor is prevented; meanwhile, compared with bidirectional rotation, the unidirectional rotation motor has longer service life. Through setting up lock core 9 to when the unable starter motor unblock of outage, lock safely or unblock through the instrument manual work. The utility model discloses an automatic formula vending machine electronic lock simple structure, the cost of manufacture is low, installation convenient operation, and the practicality is strong, is fit for using on each kind of automatic formula vending machine on the market.
