The customer mobile terminal includes a kind of or several in mobile phone, pad, laptop.
The door lock mold includes signal processing unit, middle control unit, electric control lock, and the signal processing unit includes bluetooth Signal receiving unit, user's IC card signal receiving unit and push button signalling receiving unit, the Bluetooth signal receiving unit, user IC card signal receiving unit and push button signalling receiving unit respectively it is corresponding receive bluetooth module, IC card module, key-press module letter Number and corresponding signal is sent to middle control unit, the middle control unit handles the signal received, so control electricity Control the keying of lock.
The middle control unit includes microcontroller.
Beneficial effects of the present invention are：
1. it is of the invention a kind of without networking Yunmen access control system by bluetooth module, IC card module, key-press module, it can use Bluetooth connection, brush IC card are unlocked with a variety of methods such as key-press input password, are made in all cases convenient for various users With.
2. one kind of the invention can provide voice auxiliary without Yunmen access control system of networking by voice module, help user fast Speed opens and closes door lock.
Description of the drawings
Fig. 1 is a kind of system block diagram without Yunmen access control system of networking of the present invention；
Specific implementation mode
The preferred embodiment of the invention is further illustrated below in conjunction with the accompanying drawings：
One kind is without Yunmen access control system of networking, which includes bluetooth module, and the bluetooth module is corresponding with door lock module Connection, the bluetooth module are used to receive the Bluetooth signal of customer mobile terminal and Bluetooth signal are sent to door lock module, In actual use, client can see Yunmen taboo unlocking after can applying for equipment permission in the user App of customer mobile terminal Bluetooth of mobile phone is opened in list, realizes that bluetooth is unlocked clicking corresponding lock icon, it is known technology to implement user App, specific former Details are not described herein with internal structure for reason.
The door lock module is correspondingly connected with IC card module, and the IC card module is used to read the signal of user's IC card and will Read user's IC card signal is sent to door lock module, in practical applications, it is only necessary to after user is authorized at property IC card, prohibit induction zone in Yunmen of IC card module and swipe the card, so that it may be swiped the card unlocking with controlling the realization of door lock module.
