System Overview
Prison is one of the main places where criminals are held. The construction and use of the prison’s intelligent security system will inject new concepts of scientific management into the supervision of prisons, and build a foundation for the prison management level to reach the high and new levels of the new century.
demand analysis
As a place for criminals, prisons are prone to group incidents, such as fights, attempts to escape, hostages, and internal and external collusion… In recent years, there have been a number of vicious cases in prisons. In the incident, various signs indicate that the security and intelligent management of prisons is facing a serious crisis. The main problems are as follows:
1. Collusion between inside and outside, insiders commit crimes, assist others in attempting to escape, and there is no effective control over the entry and exit of the second gate, and it is not easy to be detected;
2. Planning to escape, some criminals targeted the prison terrain and escaped when the duty officer relaxed their vigilance;
3. Escaping under hijacking, criminals hijacked police officers in an attempt to escape from the prison area and easily get out of sight of the police on duty;
4. The entry and exit of the second door of the vehicle is not easy to control, and the management is cumbersome, and it is easy for criminals to be carried out by the vehicle;
5. The entry and exit of visitors cannot be effectively registered and managed;
6. At present, it is easy to lend others to use in the form of cards.

Design
Zhongkong Biometric Prison Intelligent Management System is a set of solutions based on high security level that integrates the most advanced biometric technology, RFID technology, license plate recognition technology and multiple authentication technology. At the same time, the program is also an important application of the central control biometric technology in the prison field.
Aimed at the complex environment of the prison, this system is mainly designed to carry out effective security and intelligent management of personnel, vehicles, personnel sign in and patrols in and out of the passage; at the same time, it introduces advanced biometric finger vein recognition and camera linkage capture combination technology. Vehicles and personnel entering and exiting need to pass multiple verifications and background remote verifications before they can pass, which greatly improves the security of the passage.

Personnel entering and exiting gate AB is the core passage for prison control personnel. The security management of this passage is closely related to prison security. The security protection of this channel design is mainly composed of four parts: Armed Police Door A management, virtual card replacement management, Cross full-height gate management, and prison guard B door management. The workflow of each part is as follows:
Door A’s entry and exit process When we need to take prisoners into the prison area, we must first pass through a strictly guarded door AB. Door AB is the two most closely guarded doors in the surveillance area. They are controlled by armed police and police officers. After the card plus fingerprint verification on door A is successful, the relevant card swiping data and the pictures captured by the camera linkage will be uploaded to the armed police duty room server in time. After the armed police check the surveillance images and compare them, click the software “release” to open door A.
The security check channel and virtual card replacement process. People who enter through gate A cannot go directly to gate B. After entering gate A, personnel need to pass through the security check channel, and need to put the gate A card in their hand in the virtual card replacement area, and the personnel on duty can change to the gate B pass card before the personnel can pass through the cross full-height gate and the gate B passage.
Cross full-height gate entry and exit process The essential function of the cross full-height gate is to prevent people from following and a special obstacle. At the same time, only one person can swipe the card to pass. After fully exiting the full-height gate, the next person can enter. Achieved one-time verification, which is limited to single-person access, effectively controlling the escape of prisoners and other issues.
Door B entry and exit process Door B is managed by prison guards on duty, and the entry and exit process is the same as that of door A, which requires the on-duty prison guard to confirm it before release.
Visitor registration process. Visitors must be accompanied by police officers throughout the entire process. Visitors need to register their ID cards and fingerprints in advance. Then after the police officers lead into door A, the rest of the staff follow up one by one; when you exit door B, you need to perform fingerprint or vein verification one by one before you can exit door B. If the verification fails, an alarm signal will be generated in the background to prevent other personnel from being mixed. Go out.

The vehicle passage is mainly used for the entry and exit of vehicles. The entry and exit of the vehicles adopts advanced license plate recognition equipment, and the method of background verification is turned on. For the vehicles entering and exiting, the vehicle bottom inspection, the life detection inspection, and the integrated inspection of the man and the vehicle are strictly implemented to ensure the entry and exit. The safety of the vehicle.
Vehicle registration process Vehicles entering and leaving the prison area must be led by police officers. First, the driver must register at the prison administration section, collect biometric characteristics, and bind the vehicle information and lead police officers to ensure the safety of entry and exit. The AB door of the car shop adopts the AB door interlocking mode, and the motor that controls the electric door is used to realize the interlocking mode of operation.
The vehicle enters and exits process at door A. The vehicle performs license plate recognition verification at door A. The license plate recognition instrument automatically captures photos and uploads the license plate number to the background for display. The system automatically determines the legitimacy of the license plate; at the same time, the personnel on the vehicle need to get off the vehicle and use the fingerprint reader Fingerprint verification is carried out on the board to verify the legitimacy of the personnel, and finally, the armed police confirms the opening of the big iron gate.
Vehicle bottom scanning process: A vehicle bottom scanning system is set up between door A and door B of the passage. When the vehicle enters and exits the monitoring area, it first touches the ground coil, and the ground coil triggers the start of the system. The system can view the bottom of the vehicle from multiple angles. , Car bodies and license plates are scanned and recorded to obtain clear pictures and videos for future reference.
Vehicle life microwave inspection process
The life microwave tester mainly detects objects with vital signs in and out of the vehicle. Prevent the possibility of prisoners hiding and escape when vehicles are transporting goods, and enhance the safety of the overall vehicle through the AB door system.
After the vehicle passes the inspection at door B of the vehicle, the prison guard confirms that door B is opened, and the vehicle can enter the prison area.
Vehicle collision prevention process Set up a roadblock machine outside gate A. When there is a legal vehicle that needs to pass normally, the duty staff will lower the gate of the roadblock machine through a button, and the vehicle will pass normally. After the vehicle has passed, the staff on duty will “raise” again. The button raises the gate of the roadblock machine; when a vehicle that is forcibly rushing through the barrier is found, the police on duty can quickly raise the roadblock machine, which improves the control of the vehicle.

Function hotspot
Global interlock: Interlock across controllers can be realized. Between the set associated access controllers, as long as one of the doors is open, all the other doors cannot be opened (including normal verification to open the door, button to open the door, Open the door remotely).
Multiple verification methods: Personnel entering and exiting need to pass the card plus fingerprint/vein verification plus background verification on the AB door, and the interlock and anti-passback can be turned on under normal conditions. At the main entrance and exit, it needs to be successfully added through the comparison of fingerprints and veins. Only background verification can open the door.
Biometrics technology: The main channel adopts biometrics plus card and password method, which effectively prevents the risk of jailbreaking such as card lending, stealing and swiping.
Video linkage capture and background comparison verification: After the personnel verification is passed, the linkage video is captured and uploaded to the server. After the relevant staff on duty confirms that the local photos are consistent with the captured photos, click OK and start.
One-click video viewing: When an alarm occurs at a certain door, you can select the alarm door and click to view the live image of the scene to see the scene at a glance.
Virtual card replacement technology: All personnel entering and exiting need a virtual card replacement to obtain the next access control authority. Through the virtual card replacement, the information of the current personnel can be quickly confirmed, and the authority can be quickly confirmed to pass the customs.
Multiple alarm modes: All alarm information can be set to levels, ordinary alarms can be confirmed and processed without personnel filling in the reasons, and emergency alarms can be processed only after personnel filling in the reasons.
Number threshold technology: The threshold of the number of people in a certain area can be set. When the number of people exceeds or falls below the set number, an alarm will be generated to remind the staff on duty to pay attention.
One-key lock: When a prisoner flees, both the guards on duty and the armed police can lock the entrances and exits of AB with one button. After the lock is locked, any way of opening the door is invalid. The prison guards can release smoke bombs to deter criminals from furthering. The action will not return to normal until the pun function is lifted.
One-key opening: In the event of a fire and other emergency situations, the on-duty police and armed police can also open the two entrances and exits AB with one key after being confirmed by their superiors. The two entrances and exits can not be restored until the double opening function is lifted. When the emergency double opening and double buttons are activated, an emergency alarm signal will be issued.
External LED display: An external LED display can be used to update the number of police officers in each prison area and the status of police officers on duty in real time.
License plate recognition: It can directly convert the signal collected by the vehicle into a compilable digital number, and confirm the legality in the system, which is convenient, fast and safe.
Application area
This system can be widely used in detention centers, prisons, financial institutions, museums and other important places.
