Technical Process

1. Core of Biometric Recognition Technology

The face recognition module uses 3D structured light or infrared binocular camera to scan 87 facial feature points with millimeter-level accuracy to build a three-dimensional facial model. With liveness detection technology, it can effectively defend against counterfeit attacks such as photos, videos and silicone masks. Some high-end products integrate AI self-learning algorithms to identify changes in user makeup and differences in micro-expressions.

Fingerprint recognition uses semiconductor capacitive sensors to obtain three-dimensional data of fingerprint grooves through electric field induction, with a recognition accuracy of 500dpi. The ultra-large area sensor supports parallel entry of two thumbs, and the matching speed exceeds the 0.3 second mark. The latest technology has realized AI fingerprint repair, and the recognition rate of blurred fingerprints has increased by 40%.

2. Innovation of lock body structure and materials

The lock body is made of aviation-grade zinc alloy one-piece die-casting, and the surface is treated with nano-level electroplating, and the corrosion resistance level reaches ISO 9227 standard. It has a built-in high-precision motor drive group, supports the linkage of the sky and earth hooks, and the lock tongue extension speed is controlled at 0.8 seconds. The key chip adopts the financial-grade national secret algorithm, supports AES-256 encrypted transmission, and effectively prevents electromagnetic interference cracking.

3. Intelligent interactive system architecture

Adopts a dual-core 32-bit ARM processor and runs a customized RTOS system. Integrates Bluetooth 5.2, Zigbee 3.0 and NB-IoT multi-mode communication modules, supports localization and cloud dual verification. Equipped with a capacitive touch keyboard, supports virtual password technology, and can accurately identify valid password segments after continuously entering 20 digits.

Education: campus dormitories implement face matching to prevent tailing and ensure student safety

Outdoor facilities: smart express cabinets use live fingerprint verification to prevent malicious theft

Maintenance and maintenance

1. Daily maintenance specifications

Surface cleaning: wipe with a soft dry cloth, avoid using corrosive cleaning agents such as alcohol

Battery maintenance: It is recommended to check once every 6 months, and the life of lithium batteries is about 3-5 years

Fingerprint recognition area: regularly use dry cotton swabs to clean the surface stains of the sensor

Face recognition lens: wipe with lens cleaning paper every month to prevent oil adhesion

2. Common troubleshooting

Problem 1: High recognition failure rate

Check whether the biometrics are fully entered (it is recommended to enter 2-3 different angles)

Clean the sensor surface

Update the latest firmware version

Problem 2: Fast battery consumption

Turn off unused communication modules (such as Bluetooth)

Adjust the screen auto-off time

Check whether abnormal alarms are triggered frequently

Problem 3: Mechanical failure

Do not disassemble the lock by yourself, contact professional after-sales service to use special tools for repair

Regularly check the lubrication of the top and bottom hooks
