94v0 circuit board for smart home locks in the smart home industry / building intercom

Feature:Can be fingerprint, swipe, password unlock function.

Scope of application: Banks, government departments (focus on safety), and places with high security and privacy requirements such as hotels, school dormitories, residential quarters, villas, and hotels.

The intelligent door lock control scheme is an important step in the embedded development of the door lock, so that wireless data conversion and wireless control can be realized on the hardware. The intelligent door lock mainly adopts the serial port wifi module TLN13UA06, which is a new generation embedded Wi-Fi module product. The software and hardware interfaces are fully compatible with TLG10UA03, Bluetooth module and Bluetooth chip, which are small in size and low in power consumption.

Bluetooth chip

The embedded wifi module adopts UART interface, built-in IEEE802.11 protocol stack and TCP/IP protocol stack, which can realize the conversion between user serial port and wireless network. Supports serial port transparent data transmission mode, which enables traditional serial devices to easily access wireless networks.

The battery for smart door locks has four batteries, six batteries, and eight batteries.

Appearance characteristics

1. Security: After installing the fingerprint lock, it should not affect the function of the security door. There are no obvious security risks in the lock.

2. Stability is the most important indicator of fingerprint lock, generally need more than one year of actual use will slowly stabilize, stereotype. Consumers should choose the manufacturer that mainly produces fingerprint locks when purchasing. Such companies generally have good production experience. R&D experience is the best stabilizing factor.

3.Versatility should be applicable to most domestic security doors , the amount of modification is small. Good fingerprint lock installation time should be no more than 30 minutes. Otherwise, it is generally difficult for users to complete the installation and maintenance themselves. The versatility is well designed to reduce dealer inventory.

4.Intelligence :Adding, deleting and other operations should be very simple, users do not have to remember too many passwords and codes. The high-performance fingerprint lock is also equipped with a video display system, which is convenient for users to operate.

Functions

[1] The function of selecting a lock is to satisfy one's own needs on the one hand, and the quality of the lock . A good company often has no more than 5 high, medium and low fingerprint locks for users to choose. Users generally choose to use their suitable products: there are metal doors and wooden doors for the entrance door, there are user interior doors, common to wooden doors, also used for villa doors and so on. The basic functions commonly used are as below:

1)Can be used for multiple people to open the door, product quality should be stable, good performance;

2)Can open the door by permission (it is impossible for the head of the household and the nanny, the cleaner has the same opening management authority);

3) Can freely increase or decrease the fingerprint of the door opening (the babysitter can easily remove her fingerprints when leaving the job);

4) It is best to have a query record function (you can view the door record at any time, sometimes can become a key piece of evidence, generally with a display);

5)Appropriate with password function (the fingerprint part is the electronic part after all ,may be break down, in the temporary case, the head of the household can use the password to open the door), try not to choose the product that highlights the password function when selecting, after all, the password is not as secure as the fingerprint. There are usually 4 keys and 12 keys. Try not to use a password to open the door in daily life, which can effectively avoid being stolen;

6) Must have a mechanical key, this is a way to open the door, like the aircraft, the car has automatic control status, but still retains the manual control part, this is a safety consideration; any electronic part has an error possibility that the mechanical part should be relatively stable. The mechanical key that retains the lock is used as the alternate door opening method in the home. It can open the door and facilitate the repair in time when the electronic part of the door lock has a problem.
