In response to the requirements for the security and recognition accuracy of cabinet locks in communications, electric power, energy, chemical, IDC computer rooms, daily homes, and other occasions, a smart cabinet lock with multiple door-opening methods based on finger vein biometric technology is developed. The main method to unlock the cabinet is via finger vein unlocking; that is, the identification and verification of information by analyzing the pattern of the veins on the finger, and the achievement of identity verification and identification through biological detection. At the same time, it supports IC or ID card unlocking and mechanical manual unlocking. In order to simplify the overall structure, the internal mechanical structures of the aforementioned three unlocking methods are simplified into one. Its design focuses on the hybrid mechanical transmission structure and the finger vein module as well as utilizes the functions of each module. The principle is divided into blocks. Through processing and purchasing, the smart cabinet lock device is assembled, and its initial functional requirements are tested with physical objects. From the test results, it can be appreciated that the structural size, unlocking method, and two-way unlocking function of the smart cabinet lock meet the requirements, and its recognition accuracy is high, with good security and certain practical application prospects.
