Handheld palm print recognition intelligent door lock
The invention discloses a handheld palm print recognition intelligent door lock. The lock comprises a shell, a handle, a lock hole, a sealing frame, a sealing ring, a baffle, a single-chip microcomputer, a capacitive contact sensor, a lithium battery, an alarm, a waterproof frame, an electric control spring bolt, an infrared lamp, a transparent protective cover, a protective plate, a CCD camera, aguide groove, a sliding block, an air cylinder, a push plate, a wedge block, a chuck, a spring, a locking groove, a clamping block, a through hole, a lock cylinder, and a fixing frame. Through holding the handle by a hand, a low-power consumption capacitive contact sensor is arranged on the handle, usually, the lockset is in a dormant state, the system is awakened when a hand touches the handle.The infrared lamp and the CCD camera on the back surface are turned on, the back of the door handle is irradiated to a palm or a finger through the infrared lamp, the CCD camera acquires images, imagedata are transmitted to the single-chip microcomputer for algorithm analysis, so that registration and recognition functions are achieved. When image data is not recognized for multiple times, the single-chip microcomputer controls the alarm to give out sound to warn people in a door, and the door lock is convenient to use and safer.
本申请公开了一种手握式掌纹识别智能门锁，包括壳体、把手、锁眼、密封框、密封圈、挡板、单片机、电容式接触传感器、锂电池、报警器、防水框、电控锁舌、红外灯、透明防护罩、防护板、CCD摄像头、导向槽、滑块、气缸、推板、楔形块、卡头、弹簧、锁紧槽、卡块、通孔、锁芯和固定框。本申请通过手握把手，把手上有低功耗电容式接触传感器，平时锁具处于休眠状态，手接触把手时唤醒系统，打开背面的红外灯和CCD摄像头，门把手背面由红外灯照射于手掌或指部位，再由CCD摄像头获取图像，图像数据传入单片机进行算法分析，以此实现注册和识别功能，当多次未识别通过时，单片机控制报警器发声，对门内的人提供警示，方便使用，更加安全。
