Single-point partition security inspection system and method based on light induction

Abstract

The invention relates to a light-sensing single-point partition-type security inspection system and a method thereof. The security inspection system includes a main control unit, a transmitting light curtain group, a receiving light curtain group, a security inspection host computer and a gate. The main control unit is internally equipped with a serial Interface module and memory, the transmitting light curtain group is provided with a plurality of transmitting tubes, the receiving light curtain group is provided with a plurality of receiving tubes, the transmitting end of the transmitting tube and the receiving end of the receiving tube are arranged opposite, and the security inspection host computer is communicatively coupled and connected The main control unit, the gate is coupled to connect the main control unit and the security inspection host computer. The main control unit is used to output the carrier signal and the address selection signal, and collect the electrical signals fed back in the security inspection system, and can generate the light curtain position information according to the electrical signals. The invention can effectively judge the occlusion of the light curtain point, has high fault tolerance rate, can improve the accuracy and safety of personnel passage, has good consistency in sending and receiving, low resource occupation and high system operation efficiency.

Description

technical field [0001] The invention relates to the technical field of security inspection and passage, in particular to a security inspection system and a method thereof based on a light-sensing single-point partition. Background technique [0002] At present, in subways, passenger stations, shopping malls, office buildings, residential areas and other places with concentrated traffic, gates are usually set for safety inspection or current limiting. The gates mostly use infrared detection, and use the target object to block the infrared signal. The actual passage of people in the turnstiles, but the level of passage of the turnstiles needs to be improved. [0003] Existing gate operation, when the serial port communication is running, the resource occupancy is high, and the collection consistency is low, the accuracy of the gate pass judgment is not high, and the traffic efficiency and fault tolerance rate are low when the gate is working, resulting in poor overall safety p...

Problems solved by technology

[0003] When the existing gates are running and the serial communication is running, the resource occupation is high, and at the same time, the collection consistency is low, the accuracy of the gate passage judgment is not high, and the traffic efficiency and fault tolerance rate are low when the gates are working, resulting in poor overall security performance. Good, there are security risks

For example, the patent application number "CN201710265637.7" discloses "an infrared detection system for gates". The detection system includes an infrared emitting board, an infrared receiving board, a forwarding board and a main control board, with less wiring, easy installation, and no need for hardware dial settings , low cost, and short detection cycle, which satisfies the real-time requirements of the gate detection system, but its fault tolerance rate is low, and the accuracy of traffic is difficult to guarantee

For example, the patent application number "201710266152.X" discloses "a configuration method for the infrared detection light curtain of the gate", which corresponds the actual collected data of the infrared light curtain point to the point on the software, and finally collects the actual infrared light curtain The situation is displayed on the software interface to obtain the correct traffic status, but it has the problem that the resources of the infrared detection light curtain and the infrared acquisition control board are high, and the carrying load is large, and the electromagnetic interference generated will affect the actual infrared acquisition. Feedback, resulting in failure to obtain the correct traffic status, reducing the safety of traffic
