Intelligent entrance guard based on block chain technology

Abstract

The invention relates to an intelligent entrance guard based on a block chain technology. The intelligent entrance guard comprises a base, a door frame, a pedal, a recognizing mechanism, a loudspeaker, an indicator lamp and two passing mechanisms. Each passing mechanism comprises a driving assembly and two passing assemblies. Each passing assembly comprises a fixed shaft, a sleeve, a door plate and a supporting rod. The recognizing mechanism comprises a lifting plate, a recognizing assembly, a rail, two lifting assemblies and two hanging rods. The recognizing assembly comprises a movable plate, a camera and two movable units. According to the intelligent entrance guard based on the block chain technology, data storage is conducted through the block chain technology, and the data safety degree is high; moreover, through the cooperation of the two passing mechanisms, the function of detecting people one by one is realized, it is avoided that other people follow legal persons to pass by the entrance guard, and the safety and reliability of the device are improved; furthermore, through the recognizing mechanism, the lifting plate descends to the head top positions of people, the cameratakes pictures of human faces at different angles, the human face recognizing precision is improved, and the identity verification accuracy is ensured.

Description

technical field [0001] The invention relates to an intelligent access control based on block chain technology. Background technique [0002] Blockchain technology uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes intelligence composed of automated script codes. A new distributed infrastructure and computing method that uses contracts to program and manipulate data. It is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. [0003] Blockchain technology has a high degree of data security and is widely used, including access control devices commonly used in the security field. [0004] The access control of the prior art generally adopts the traditional data encryption method, which is easy to cause data l...

Problems solved by technology

[0004] The access control of the prior art generally adopts the traditional data encryption method, which is easy to cause data loss, and for the convenience of use, the access control of the prior art mostly installs face recognition cameras on the access control, but the positions and angles of these cameras are fixed. However, there are deviations in the height of the crowd for identity verification and the angle of the face, which leads to frequent deviation errors in the face recognition of the camera, and the general security performance of the existing access control devices is reduced. When some legitimate personnel pass through the access control, others who do not The inspected personnel tend to pass through the gate with legitimate personnel during the gate closure period, which reduces the practicality of the existing gate control device
