Anti-trailing system and device based on number of video viewers

Abstract

The utility model relates to an anti-trailing system and a device based on the number of video viewers, which solves the defect of systematic chaos caused by miscount and two-way pass trailing prevention in a controlled area. The system comprises a video controller including a central control unit; an identity detector matched with access controllers at a door A and a door B, transmits an acquired identification code together with a door-opening request signal to the central control unit; image acquisition devices arranged at the door A and the door B collect environment video images of a monitoring target at the doorway, convert the acquired video images into digital signals and then transmit the digital signals to a video viewer number statistics module in the central control unit for real-time statistics, and store the result; and the video controller sends result information and the video images stored by a central processing unit to a management terminal of a management center so as to judge and process the information, and then the information is converted into a standard comparison parameter which is finally retransmitted to a storage unit in a lock controller in the access controller. In the invention, the structure is simple and the safety coefficient is high.

Description

technical field [0001] The present invention relates to the relevant technical field of an intelligent access control system, in particular to an anti-tailgating system and device, in particular to an anti-tailgating system and device based on video counting of people. Background technique [0002] Anti-tailgating means that when a person with a legal identity enters a safe area, he takes relevant security measures to prevent people who do not have the authority to enter the safe area from following him. The currently known safety measures taken to prevent tailgating are to install two doors at both ends of the controlled area, and use the access control controller to control the interlocking linkage of the electronic locks of the two doors. When one door is opened, the other door will not be locked. Open, only when both doors are closed, can any one of them be opened. And the premise of being able to open one of the doors is that the other door is locked. If the door is no...

Problems solved by technology

[0004] The present invention is an anti-tailgating system combined with intelligent video monitoring, which overcomes the shortcomings of the prior art that cannot realize two-way traffic anti-tailgating in the controlled area, and is prone to system operation logic confusion caused by counting errors. The number of people in the area is calculated, which can accurately judge the number of people entering and leaving, prevent tailgating, and have a higher safety and accuracy factor. The technical solution adopted is: a system based on video people counting and anti-tailgating. There are two doors A and B in the system. , access control devices, lock control devices, alarm devices set at doors A and B, management terminals set in the management center, and instant information collection and storage devices set in the management terminals, the system structure also includes a central The video controller of the control unit, and the identity detection device matched with the access control devices at the A and B doors, transmit the collected identity codes together with the door opening request signal to the central control unit, and the image acquisition devices set at the A and B doors At the same time, the device collects the environmental video images at the door where the monitoring target is located, and converts the collected video images into digital signals through the A / D converter, and then transmits them to the video people counting module in the central control unit for real-time statistics. Stored in the memory, the video controller sends the result information and video images stored by the central processor to the management terminal of the management center by means of the network interface and supporting communication protocols, and the management terminal judges and processes the received information and converts it into a standard The comparison parameters are sent back to the corresponding storage unit of the lock control device in the access control device through the central processing unit.
