Chapter III Overview of System Solutions
The overall plan is the top priority of the prison’s intelligent management and security system construction. Our company has conducted detailed investigations on the escape incidents in recent years, and according to the work process of prison guards and the law of activities of prison detainees, the intelligent management of the prison is carried out. And the construction of the security protection system is divided into three parts: the intelligent management system of the prison area, the intelligent management system of the activity area outside the prison, and the intelligent management system of parole medical treatment. The three parts complement each other and jointly build the prison intelligent management and security protection system. .
Below we will explain in detail the three components of the prison’s intelligent management and security system:
5.1 Intelligent management system for prison area
The construction of an intelligent management system for prison areas mainly includes the following parts: 1. Perimeter management systems such as prison walls, production areas, and living areas; 2. Real-time positioning systems for access control and area of living areas, production areas, restaurants, prisons, etc.; 3. Gun management system for guard posts and armed police;
1) Perimeter management system for prison walls, production areas, living areas, etc.
Prison wall
The prison fence is the last security guarantee of the prison’s intelligent management and security system, which prevents the prison from being detained.
The most important checkpoint for personnel to escape from prison plays a decisive role in the security of the entire prison system. Therefore, the requirements for the stability, timeliness, and anti-interference of the equipment are extremely high. In order to ensure the stable operation of the system, we will design the plan Fang gave thorough consideration.
The prison wall perimeter management system is composed of: electronic fence or leaking cables, and the alarm host communication is transmitted to the monitoring center through the personnel positioning management system.
Prison perimeter function: prevent detainees from breaking out of prison; when detainees are close to the electronic fence about 3 meters (with an error of not more than 50 cm), the alarm device will automatically start the alarm, and the large screen will display the scene of the incident-breaking into the restricted area and being in custody Personnel identity information, location information and online viewing of the scene through the video linkage function;
Prison perimeter installation method: along the middle of the fence or 30 cm from the fence shallowly buried underground (the perimeter cable antenna needs to be covered with PVC pipes to prevent the antenna from bending and deforming, being corroded by water, etc.), install a perimeter IoT every 50 meters Orientation monitor and a waterproof test electronic label (when the IoT orientation monitor is damaged, it can be detected in the background to ensure the stable operation of the IoT orientation monitor), and a directional reader is installed as a signal receiver every 80 meters .
Production area, living area, etc.
The boundaries of production areas and living areas also need to install IoT directional monitors + perimeter IoT directional monitors + perimeter cable antennas to prevent detainees from entering illegal areas without permission and prevent accidents; The prison guards of the monitoring center and senior prison leaders can set the boundaries according to actual needs, such as: how far away the detainees are from the boundary and call the police, detainees are not allowed to enter a certain area during a certain period of time, and detainees can Enter the perimeter to clean the lawn, etc.;
2) Gun management system for sentries and armed police
The construction of the guard post and armed police gun management system includes two parts: first, the intelligent monitoring subsystem of guard post and armed police guns; second: real-time tracking and positioning management subsystem for perimeter prison guards;
◇ Intelligent monitoring subsystem for sentry and armed police guns
The construction plan of the intelligent monitoring subsystem for the sentry and armed police guns
A signal receiver and an IoT directional monitor are installed inside or on top of each sentry post, which is responsible for receiving the electronic tags of armed police firearms and emergency help signals issued by the armed police (detainees snatching firearms, detainees fighting, detainees having abnormal behaviors, etc. ) And is responsible for transmitting the information to the back-end monitoring center through the RJ45 network; the armed police’s gun butt is equipped with a special electronic tag, and the electronic tag will send the electronic tag signal to the signal receiver in real time. Etc.) If the information sent by the electronic tag is not detected, the alarm system of the monitoring center and the security monitoring system will automatically start. At this time, the LCD display will display the current sentry situation, the identity information of the armed police on duty, the position information of the armed police on duty, etc. The monitoring center can follow The actual situation dispatched nearby armed police to assist in handling emergencies to prevent serious situations from occurring.
◇ Perimeter armed police patrol real-time tracking and positioning management subsystem
Perimeter armed police patrol real-time tracking system functions:
1) Regional positioning, through the IoT directional monitors and signal receivers installed on the fence, regional non-precision positioning can be achieved
2) Alarm for firearms and armed police when they leave their positions
3) The armed police failed to patrol the scheduled route with guns, and the system called the police
4) When the armed police encounter an emergency, they call the police for help
5) Armed police and gun track playback
3) Real-time positioning system for access control areas such as living areas, production areas, restaurants, prisons, etc.
The real-time positioning system for access control areas such as living areas, production areas, restaurants, prisons, etc. includes two parts: first, the regional access control management system; second, the regional real-time positioning system;
◇ Regional access control management system
Investigation on the status quo of access control management: Detainees from the living area to the production area to work, eat in the restaurant or return from the production area to the living area, are led by the team leader and registered in and out through the only channel inside and outside the gate. At present, manual registration and counting of the number of people are used, and the work intensity of prison guards is very high. Through the regional access control management system, the data of the roll call can be directly transmitted to the prison guard’s PDA or background monitoring center through the local area network or WIFI, GPRS, etc., thereby reducing the work intensity of the prison guard.
Regional access control management system function: real-time roll call and specific authority settings for detainees from the prison living area to work and production areas, restaurants, cells, etc., when they pass the gate (gate) (a detainee can only pass the access control within a specified time, Otherwise, an alarm will be triggered) to strengthen the standardization and safety of prison management;
Install IoT directional monitors and signal receivers in the living area and production area channels (determined by the on-site environment), because this channel is the only channel for all detainees to enter the production area or return to the living area, and there is a large daily flow of people for the reliability of the system Higher performance, place IoT wireless nodes in the channel;
The system will automatically record the entry and exit information of all detainees (personal information, quantity, entry and exit time of detainees), and can automatically match the rules of the background system. When detainees who do not meet the passing rules pass, the duty room immediately performs sound and light Call the police and record violations.
◇ Regional real-time positioning system
The regional real-time positioning system mainly monitors personnel in large areas such as prison living area, work area, and activity area, through the Internet of Things omnidirectional monitor, the Internet of Things directional monitor, the Internet of Things wireless node, and the Internet of Things network. With the combination of relays, a full-scale position monitoring of production areas, activity areas, etc. can be performed to understand the details of detainees and prison guards in real time. You can intuitively understand the actual number of personnel in the area, personnel information, etc., which can be clear through the software. It greatly reduces the workload of prison guards and realizes the way to demand police force from science and technology.
【Function description】
In indoor and outdoor labor places, key prisons, toilets, squares and other areas, signal coverage is achieved through the combination of IoT omnidirectional monitors and directional positioning receivers;
The system will roll the names of detainees in the area every 5-10 seconds (settable). When the detainees leave the designated area, the system will immediately alarm and display the alarm location and information of the detainees in violation of the rules.
The system can also control and restrict each area according to the event segment. If a person enters the area during the controlled time period, the system will immediately sound and light alarm and notify the nearest prison guard to deal with it in time, which greatly avoids accidents. , The setting of controlled time can be flexibly changed with the prison regulations.
5.2 Intelligent construction of medical service institutions outside prison
The overall construction of the prison’s intelligent management and safety protection system needs to take into account the intelligent construction of medical service institutions for detainees to seek medical treatment. In recent years, prisoners have used the assistance of medical treatment to escape from prison from time to time. The painful lessons remind us that we must not ignore the detainees. Take care of all aspects.
Taking into account the cost of intelligent construction of the entire prison staff and the particularity of medical service institutions outside the prison area, the intelligent construction of medical service institutions outside the prison area can adopt a policy of focusing on deployment and control, focusing on the future, and gradually improving, such as: entrance and exit of the building, Install positioning equipment for inter-floor passages, electronic fences, and hospital entrances and exits to prevent accidents;
5.3 Intelligent construction of out-of-office location monitoring
The intelligent construction of out-of-office location monitoring is mainly for the detainees to go out to work and seek medical treatment outside, and for the temporary out-of-work area and the internal area of the driving vehicle, a remote RFID monitoring, positioning and tracking method is adopted to realize the mode of requesting police force from science and technology.
Install a set of omnidirectional readers or PDA handsets on the roof of the police car or inside the police car to monitor the overlapped area in real time through a combined method, and at the same time transmit the monitoring information back to the prison information center through the GPRS network in real time.
