A waterproof rubber strip is provided to form a seal between the cover plate 18 and the surface of the outer door lock housing assembly 1, further preventing water from entering the keyhole.

For the convenience of understanding the utility model, the utility model is further described below in conjunction with a use process:

When in use, install the front lock body on the outside of the door, and the rear lock body on the inside of the door. Since both the front lock body and the rear lock body are packaged components, they are connected by connecting cables, so they can be installed easily. There is no need to drill additional holes on the door, align the drive shaft of the deadbolt with the connection hole 10 on the outer handle 2 and the inner handle 8, and connect the connecting cable through the through hole on the original mechanical national standard lock on the door. The front lock body and the rear lock body can be fixed on the surface of the door by adhesive.

Install four AA dry batteries in the battery compartment 15, and install the battery compartment cover to package the dry batteries in the battery compartment 15. Input the unlock signal on the operation panel 3 and store it. The input signal will be converted by the A/D converter 14 In order to send an identifiable signal to the controller 13 and the memory 12, when the input unlock signal matches the initially set unlock signal, the controller 13 sends a signal to instruct the driving device 20 to unlock. After unlocking, people turn the outer handle 2 to drive the dead bolt to shrink, thereby opening the door.

When unlocking with a key, the key rotates and drives the member to move the deadbolt limiter, so that the fixed shaft escapes from the hole on the rotating shaft of the outer handle 2, so that unlocking can be realized without the action of the driving device 20, so as to avoid failure of the driving device 20 Or when the power supply is exhausted, the lock cannot be unlocked.

The inner handle 8 is provided with a manual switch 9, and an auxiliary dead bolt is also arranged below the dead bolt linked with the handle. The manual switch 9 is linked with the auxiliary dead bolt. Down reset, so as to realize locking and unlocking the door from inside the door.

If the battery power in the battery compartment 21 is exhausted and people do not replace the battery in time due to negligence, they can temporarily purchase a 9V battery, connect the 9V battery to the backup power supply interface 22, and then normally unlock by inputting the unlock signal. Change the battery in the battery compartment 21, also can directly unlock with key.

The size of the front lock body and the rear lock body of the utility model matches the mechanical national standard lock body, so the modification of the mechanical national standard lock body can be realized, and the mechanical lock can be changed into an intelligent lock. If the front lock body or the rear lock body is damaged or When the user wants to replace it for aesthetic reasons, it can also be easily removed and replaced. The mechanical lock body inside the door does not need to be replaced, and the door will not be damaged.

The display screen can display date, time and remaining power, and this function can be realized by existing technology, and can refer to the technology of displaying time and date through LCD display screen or LED display screen on the existing door.

The wireless communication of the utility model adopts the zigbee protocol transmission, which has low energy consumption and cost, large capacity and high security, and can realize anti-peeping password technology. If it is not convenient to cover, you can enter a number greater than six digits, and any six digits coincide with the unlock password, that is, the unlock can be realized. In order to improve communication reliability, this paper adopts the method of repeated transmission in the communication protocol. The electronic lock repeatedly sends each set of data 5 times. After receiving this set of data, the intelligent monitor uses the law of large number decoding to correct errors, ensuring Accuracy of Data Received. In addition, in order to save memory, it is necessary to use preprocessing technology for the received data, that is, after receiving a piece of data, first compare the data with the set threshold value, if it is greater than the threshold value, an over-limit alarm will be issued; if it is less than threshold value, compare the data with similar data received that day, and keep the larger one. In this way, the data stored every day is the maximum value among similar data.

In the utility model, controller 19 adopts 51 single-chip microcomputers, and its internal chip adopts the chip of existing electronic lock to realize the above-mentioned functions, and the program inside the chip is not the innovation point of the present utility model, and its program is not mentioned here. To repeat, the driving device of the electronic lock can be a motor. An alarm device can also be set, such as a buzzer, when the unlock signal input error reaches a certain number of times or when the lock is disassembled abnormally, the buzzer alarm will be triggered. In addition to playing the role of face recognition and unlocking, the camera of the utility model can also be connected with monitoring equipment such as a computer to monitor the situation outside the door.

In the utility model, the electrical connection means that the transmission of information and electric energy can be realized between the connected components, which can be realized by using cable connection.

The above is only a preferred embodiment of the utility model, not all embodiments of the utility model, and is not intended to limit the utility model. Any modifications made within the spirit and principles of the utility model are equivalent to Replacement, improvement, etc. should all be included in the protection scope of the present utility model.

Except for the technical features described in the description, the rest of the technical features are known to those skilled in the art.
