Domestic fingerprint chips used in the field of smart door locks

Smart door lock refers to a technical composite lock that is improved on the basis of being different from traditional mechanical locks, and is more intelligent and simple in terms of user safety, convenience, identification, and management. The smart door lock is the executive component for locking the door in the access control system. It is widely used in the following places: banks, hotels, school dormitories, residential quarters, villas, hotels (focus on convenient management).

Fingerprint locks are intelligent locks, which are the crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. The characteristics of fingerprints have become important evidence for identification and are widely used in public security criminal investigation and judicial fields. Fingerprint authentication has the characteristics of convenience, speed and precision. With the popularization of technology and the development of smart homes, more and more people have begun to choose fingerprint locks.
The core components of the pattern lock: main board, clutch, fingerprint collector, cryptographic technology, microprocessor (CPU), intelligent emergency key. As a fingerprint lock, the most important thing should be the fingerprint chip. Fingerprint locks are security products produced through the precise combination of electronic components and mechanical components. The essence of fingerprint lock is nothing more than three aspects of safety, convenience and fashion.
Fingerprint chips refer to chip products with embedded fingerprint recognition technology, which can realize fingerprint image collection, feature extraction, and feature comparison on a chip. Developers can easily realize the fingerprint recognition function, which greatly reduces the threshold of the fingerprint recognition industry. , has a very positive role in promoting the promotion of fingerprint identification.
In recent years, with the rapid development of the domestic fingerprint chip market, the application and research and development of core production technologies related to it will surely become the focus of attention of enterprises in the industry. Understanding the research and development trends, process equipment, technology applications and trends of core technologies for fingerprint chip production at home and abroad is critical for companies to improve product technical specifications and market competitiveness.
The fingerprint identification chip contains two modules, the fingerprint identification module and the touch wake-up module.
Fingerprint identification module: The fingerprint identification chip is responsible for collecting fingerprint information and uploading the fingerprint image to the fingerprint identification algorithm chip; the fingerprint identification algorithm chip is responsible for controlling the working status of the fingerprint identification chip, and completing fingerprint registration, fingerprint deletion, and fingerprint matching.
Touch wake-up module: used to detect the user's touch action. During the system sleep period, if the user touches the fingerprint recognition module, it will send a touch wake-up signal to the main control MCU.
