The technical parameters of smart locks mainly include the following aspects:
Sensor module: Smart locks usually use optical or semiconductor sensors, such as CMOS or Swedish FPC surface sensors. Optical sensors are low-cost but large in size, suitable for fixed scenes such as door locks and safes; semiconductor sensors are high in precision and strong in anti-static interference, suitable for portable devices.
Data processing unit: The core component is the microprocessor (MCU), usually 51 single-chip microcomputer or ARM Cortex-M series, responsible for fingerprint feature extraction, comparison and instruction issuance. The encryption chip supports AES-256 or national secret algorithm to ensure the security of fingerprint data storage and transmission.
Drive control module: It includes a high-torque motor and a clutch. The motor torque must be ≥4.5Nm to drive heavy anti-theft doors or sky hooks; the clutch realizes the conversion of electronic signals to mechanical actions, and automatically switches the emergency key in case of failure.
Power management system: Dual-battery redundant design, main battery and backup button battery work together, support low power mode (standby power consumption ≤ 100μA), and battery life up to 18 months.
Safety mechanism: Including dynamic feature matching technology, multi-modal verification (fingerprint + password + temporary key) and anti-environmental interference design (wide temperature range operation and anti-electromagnetic shielding).
Other technical parameters: Such as 170° wide-angle smart cat eye and 4-inch large screen, finger vein recognition technology, 5-level automatic warning of safety hazards and 4-level indoor intelligent protection functions, etc.
