Intelligent electronic door viewer

Abstract

The invention relates to the technical field of door viewers, and specifically relates to an intelligent electronic door viewer. The intelligent electronic door viewer comprises an infrared illuminating lamp, an optical structure, a camera, a door-outside loudspeaker, a door-outside microphone, a far-infrared probe, a door-outside photoresistor, a lock-inside photoresistor, a handle contact, a lock tongue contact, a doorbell button, a 6 V direct current power supply, a 3.3 V voltage-stabilizing circuit, a master control chip, a clock circuit, a crystal-oscillation circuit, a reset circuit, an SD card storage circuit, a touch control liquid crystal display screen, a door-inside microphone, a door-inside loudspeaker, a Wi-Fi transmission module, and a power indicating lamp. The far-infrared probe can determine whether there is someone approaches the door, the handle contact is matched with the lock tongue contact so that whether there is someone trying to unlock the door without keys can be determined, and the lock-inside photoresistor is positioned at the inner part of a lock so that whether the lock is destroyed by violence can be determined. Compared with the prior art, a sensor employed by the intelligent electronic door viewer is simple and effective, mode determination is intelligent and various, and the security of access control can be effectively improved.

Description

Technical field [0001] The invention relates to the technology of the cat's eye field, in particular to an intelligent electronic cat's eye. Background technique [0002] The cat’s eye is an optical instrument often used on the door. It is generally composed of multiple concave-convex mirrors, which can expand the field of view. You only need to open a small hole in the door, and the people in the room can observe the situation outside the door before opening the door. Have a certain understanding of the door knocker and avoid the danger of robbery after opening the door. [0003] With the development of technology, new electronic cat eyes have gradually replaced traditional cat eyes. However, most electronic cat eyes on the market currently aim to improve existing functions, such as using a camera and a display to improve the inconvenience of traditional cat eyes. A series of humanized functions such as taking photos and videos are added. However, the potential of electronic pee...

Problems solved by technology

[0003] With the development of science and technology, new electronic peepholes have gradually replaced traditional peepholes, but most of the electronic peepholes currently on the market are for the purpose of improving existing functions, such as using cameras and displays to improve the inconvenient observation of traditional peepholes. Added a series of user-friendly functions such as taking pictures and videos

However, the potential of electronic peepholes in improving the security performance of the access control system has yet to be tapped. The invention patent CN201310162292.4 discloses an intelligent electronic peephole, which not only introduces commonly used modules such as cameras, but also introduces photoresistors to judge daytime Or in the dark night, the infrared sensor module judges whether someone is approaching, and the image processing module recognizes the person approaching the door, which improves the security of the access control system, but its mode judgment is too simple. Once someone approaches, it responds, and even directly calls the police in night mode. Considering the situation of passers-by, if the image recognition module recognizes the person who has been entered, it will automatically open the door, which is easy to be used by people, which reduces the security of the access control system, and the cost of image recognition technology is too high to be realized.

Invention patent CN201310193420.1 discloses a multifunctional access control system, which adds mobile phone remote terminal control, which improves the user's control over the access control system. However, using the CDMA3G network as a communication means requires an additional phone card on the door, and A certain flow rate increases the investment cost and use cost

At the same time, the above two electronic cat eyes did not consider the situation of ordinary passers-by and violent vandals
