Intelligent door lock

Abstract

The invention relates to an intelligent door lock which includes an outdoor door lock panel and an indoor door lock panel. The outdoor door lock panel is successively provided with a microphone, a human body inductor, a camera, a fingerprint sensor, a password keyboard, a doorbell and a speaker from top to bottom, the indoor door lock panel is provided with a manual rotary knob for controlling a lock cylinder to open the door, the indoor door lock panel is internally provided with a battery and a main control circuit board, the battery is electrically connected with the main control circuit board, the microphone, the human body inductor, the camera, the fingerprint sensor, the password keyboard, the doorbell and the speaker are electrically connected with the main control circuit board, the main control circuit board is provided with a communication module for being in communicating connection with a mobile phone, the wide angle of the camera is 120 degrees to 140 degrees, the camera is obliquely arranged upward, and the angle of the axis of the camera and the horizontal direction is 15 degrees to 30 degrees. According to the intelligent door lock, the shooting range is wide through arrangement of the direction of the camera, shooting of the whole image of a person in front of the camera is facilitated, and negligence and potential threats caused by shooting dead ends are prevented.

Description

technical field [0001] The invention belongs to the field of locks, and in particular relates to an intelligent door lock. Background technique [0002] With the development of economy and technology, the current way of unlocking the lock by turning the lock cylinder with the mechanical key to drive the brake tumbler to turn has changed. In recent years, with people's higher requirements for safety and convenience, non- As a mature technology for user identification ID, mechanical keys can be divided into four categories: 1. Combination locks, which are mainly used for high-security locks such as safes; 2. Inductive locks, which are divided into contact locks and non-contact locks. Type locks, such as IC card locks, are widely used in parking lots, subways and other places. The configuration is easy to carry and the price is low; 3. Electromagnetic locks are made using electromagnetic principles. The disadvantage is that the door cannot be closed when the power is off, so it...

Problems solved by technology

For a camera with a wide angle of 180°, since the shooting angle is relatively large, the shooting range of the camera is wider at this time, and the corresponding imaging pixels will increase, so the captured video or picture will occupy a large memory, affecting The computing speed of the main control circuit board also affects the transmission speed during data transmission. At the same time, the price of the camera with a wide angle of 180° is relatively high; for the camera with a wide angle of 120°-140°, when the camera is placed flat, the The wide-angle angle is limited. Therefore, the height of the portrait that the camera can capture is limited. When the person standing on the camera is tall, the camera cannot capture the face image of the person. Usually, the camera cannot capture the image of a person with a height of about 2 meters. Facial features, thus causing the problem of shooting dead angle
