With the continuous improvement of people's living standards, people are increasingly fond of various intelligent products, and the use of intelligent products can significantly improve people's life experience. And smart door locks are a type of home device that has emerged in recent years. We almost need to close and open doors every day, and traditional mechanical locks require the use of keys to open the door, which is very inconvenient. And the intelligent door lock automatically locks the door when leaving, which can automatically open the door when returning home, greatly saving everyone time and energy. The Tuyang Technology intelligent door lock solution, below is a detailed explanation of the knowledge!

1、 Design Principle of Intelligent Door Lock Scheme

The intelligent door lock consists of a lock, a power supply, and a relay driver program, and the lock mainly consists of three parts: sensors, microcontroller chips, and load devices. The sensor senses the code signal on the card and provides the signal to the microcontroller. The microcontroller compares the code and controls the opening of the corresponding device.

2、 Introduction to the Development Function of Intelligent Door Lock Scheme

The intelligent door lock solution adopts the Jerry AC791N/AC6323A chip, packaged in QFN, with peripheral auxiliary execution circuits. It is developed and designed through a microcontroller program, and ultimately the intelligent door lock can achieve the following functions:

(1) Password settings, enter the password correctly, click the unlock button to automatically unlock, and click the lock close button to achieve lock closing;

(2) Password can be manually modified;

(3) If the password is entered incorrectly midway, it can be deleted as a whole or bit by bit;

(4) If the password input is incorrect, the password input area will be locked, accompanied by a brief alarm sound, and re input will be prohibited for a certain period of time;

(5) Backlight display, touch display backlight, still clearly visible in dark environments.

3、 Features of intelligent door lock solutions

(1) Long standby time of 150 days with two No. 7 batteries;

(2) Alarm function, triggered by multiple incorrect password inputs;

(3) Emergency unlocking, forgetting the password can still be unlocked through a backup key;

(4) The indicator light is displayed, and the low battery indicator light is flashing.

The structure diagram of the intelligent door lock PCB developed by Tuyang Technology is fully compatible with other intelligent door lock male mold shells on the market. The PCB structure of the door lock can also be customized according to customer requirements. The intelligent door lock PCB is a single panel, and the shape of the product can be designed and changed by oneself. Merchants can create more different shapes to meet market demand.
