Walk through metal detector based on block chain technology

Abstract

The invention relates to a walk through metal detector based on a block chain technology. The detector comprises a top plate, a bottom plate, a pedal and two supports, and further comprises an identification mechanism and a detection mechanism. The identification mechanism comprises a retractable assembly and a camera. The retractable assembly comprises a power unit, a fixed block, a telescopic frame, a retractable plate and two hinge blocks. The detection mechanism comprises a detection frame and two lifting assemblies. Detection assemblies are arranged on the periphery of the detection frame. The detection assembly comprises a first motor, a rotary disc, a fixed rod, a swinging rod, a connecting shaft and a detection device. According to the walk through metal detector based on the blockchain technology, data storage is carried out by adopting the block chain technology, so that the degree of data security is high; and an identity verification on a person to be detected is performedthrough the identification mechanism, and a metal detection on the person to be detected can be performed through the detection mechanism, so that no human detection is needed, and human resources are reduced.

Description

technical field [0001] The invention relates to a security gate 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. This includes the security gate. [0004] The security gates of the prior art generally adopt the traditional data encryption method, which is easy to cause data loss. Moreover, when the security gates of the prior...

Problems solved by technology

[0004] The security gates of the prior art generally adopt the traditional data encryption method, which is easy to cause data loss. Moreover, when the security gates of the prior art are in operation, it is necessary to manually detect the metal of the personnel to be inspected, which increases the labor cost. It reduces the practicability of the security gate, not only that, the fixed setting of the camera of the existing security gate, the height of the person to be checked is high or low, making the camera unable to perform identity verification on the face of the person to be checked, which reduces the security of the camera verification. precision of identity
