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

Abstract

The invention relates to a single-point partition type security check system and method based on light induction. The security check system comprises a main control unit, a transmitting light curtain group, a receiving light curtain group, a security check upper computer and a gate machine, a serial interface module and a memory are configured in the main control unit, 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 ends of the transmitting tubes and the receiving ends of the receiving tubes are oppositely arranged, the security check upper computer is in communication coupling connection with the main control unit, and the gate machine is in coupling connection with the main control unit and the security check upper computer. The main control unit is used for outputting a carrier signal and an address selection signal, collecting an electric signal fed back in the security check system, and generating light curtain point location information according to the electric signal. According to the invention, the shielding condition of the light curtain point can be effectively judged, the error-tolerant rate is high, the accuracy and safety of personnel passing can be improved, the transmitting, receiving and acquisition consistency is high, the resource occupation is low, and the system operation efficiency is high.

Description

technical field [0001] The invention relates to the technical field of security inspection, in particular to a light-sensing single-point partition type security inspection system and a method thereof. Background technique [0002] At present, in subways, passenger stations, shopping malls, office buildings, residential areas and other places where the flow of people is concentrated, gates are usually set up for safety inspection or current limit. The actual passage of the people in the gate, but the traffic level of the gate needs to be improved. [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 applicatio...

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
