Who has the latest overall security solution for China Modern Prison?

Construction scheme of security system in detention center

I. Overview

With the gradual implementation of the National Prison Informatization Construction Plan, combined with the relevant standards such as the Technical Construction Specification for Detention Centers. At present, it is the main work to scientifically and reasonably upgrade the security system of detention center and establish a comprehensive management platform with three-dimensional protection, intelligent application and humanized management. Among them, the video monitoring system has the intuitive function of real-time monitoring, and can be integrated with other subsystems, which makes the management system of the whole detention center intelligent and improves the reliability and stability of the monitoring system and protection function. Adopting mainstream technology, scientific planning and reasonable construction, making the system forward-looking and advanced, is the goal and direction of system construction.

Second, the demand analysis

The detention center shoulders the heavy responsibility of detaining and reforming detainees. As a prison manager, public security organs should provide a humanized and scientific management environment on the one hand, and ensure the absolute safety of prison managers and detainees on the other. How to take care of both? It is a problem that managers, executors and supervisors need to think together at present. Therefore, we must adopt more intelligent products in technology, adopt more scientific methods in system, and adopt more humanized means in management to realize it step by step.

Typical subsystems of existing detention centers are:

Communication command system; Supervision information system; Emergency alarm system; Monitoring system; Perimeter control system; Prison access control system; Detainee reporting system; Police patrol management system; Audio-visual education (broadcasting) system; Interrogation command system; Conference management system; Contraband detection system.

Status analysis of monitoring system;

1. The original system was built earlier, and there have been many transmission bottlenecks, which can not meet more and more information transmission applications.

2. The original architecture and functions of each subsystem are relatively independent and simple, which does not meet the requirements of comprehensive digital application.

3. The mainstream analog-digital combination scheme was adopted in the early stage, but there are still bottlenecks such as seamless integration, mutual control of resources and unclear monitoring.

4. Some digital schemes implemented recently have not really unified the interface standards between new technologies and various business systems; And it doesn't fully show the advantages and highlights of digital application.

5. In addition, the linkage and management between various systems basically stay in the stage of "horizontal linkage", that is, they do not have the "three-dimensional" intelligent protection and information processing linkage ability, nor do they have the rapid response and comprehensive command ability for emergency response.

Third, the design ideas

Our design philosophy:

Synchronization of system planning and construction, synchronization of system design and application,

System realization and function synchronization, system application and management synchronization.

It reflects the high consistency of the four main stages of planning, design, implementation and application, and avoids the problems of unsynchronized planning, limited design, serious derailment of scheme functions and practical applications, and incomplete integration of the system into information management under the existing framework. So as to establish a set of advanced technology, practical function, stable and reliable safety monitoring system.

The prevention system should not only meet the existing application requirements, but also be forward-looking and advanced, so that the whole system has strong expansibility, compatibility and maintainability.

System schematic diagram:

According to the authority and level of administrative management, it is divided into three levels, namely, the third-level sub-control center (the sub-control management center of this layer), the second-level monitoring center (the monitoring center of our hospital) and the first-level command center (the public security monitoring center). Based on the monitoring center of our hospital, it takes into account the command and management functions. At the same time, the network sub-control client for managing police officers can realize real-time supervision within its scope, and the sub-control client led by it can easily realize overall supervision through the network.

Combined with the management platform, the three-dimensional monitoring mode is adopted, and the reasonable layout and unified integration are carried out according to different monitoring areas, different monitoring information and different application systems, which not only meets the application of each subsystem in different areas, but also realizes the authority control of comprehensive management and the requirements of emergency plan disposal. Make the monitoring platform have a certain management width and depth.

Fourth, the system composition

Aiming at the current security system of detention center, we take audio and video monitoring as the core, and integrate perimeter alarm, access control, AB door, entrance and exit management, visual intercom, broadcasting, patrol and other subsystems for linkage. Combining three technologies: three-dimensional protection, high-definition monitoring and intelligent analysis, a powerful integrated safety management platform is built.

According to different monitoring areas, technologies such as high-definition digital monitoring, intelligent video analysis, networked sub-control, real-time information release, radio frequency identification and positioning (RFID), GPS positioning patrol, intelligent sound detection and access control video linkage analysis can be closely infiltrated, correlated and complemented, making it a comprehensive information management platform with scientific organizational structure, rigorous operation logic and intelligent application.

High-definition monitoring equipment, such as high-definition camera PE8080HD·, is used in important entrances and exits and large-scale on-site monitoring; Combined with video intelligent analysis in perimeter prevention, such as intelligent analysis equipment PE 5010; ; In the image control output, the full digital high-definition matrix PE90FH is adopted, which is fully compatible with existing standard-definition signals and high-definition signals, and can be easily realized in both network and non-network modes, supporting large-screen splicing and image processing functions.

The overall functional design revolves around three characteristics: stereoscopic, high-definition and intelligent.

Verb (abbreviation of verb) scheme and characteristics

1, transmission scheme:

Trunk transmission adopts optical fiber, and office network and monitoring information network are established respectively. The collection of monitoring information is mainly digital, supplemented by analog, and mainly in standard definition such as high definition; Nodes whose information points cannot be transmitted digitally are extended and expanded in an analog way.

As shown in the figure below:

Transmission characteristics: Red Apple passive optical network or node optical transceiver should be used for the collection of less peripheral information and more nodes, which saves cost and is easy to manage; In information-intensive areas such as prisons, Red Apple multi-service optical transceiver transmission platform should be adopted to make it cost-effective.

Schematic diagram of equipment transmission integration:

Application features: According to different application requirements, the most suitable optical transmission network and equipment are adopted respectively, so as to minimize equipment risk and transmission risk and improve system security and efficiency.

2, the overall construction framework of the system:

Features:

A high degree of system integration is based on video surveillance, combined with other subsystems, and adopts digital open interface, which makes the management ability of the platform more perfect. The distribution of network construction makes the desktop application and child control construction very flexible.

The central system adopts the latest PE90FH digital matrix of Red Apple, which is convenient to integrate all other security subsystems such as access control, patrol, alarm, entrance and exit. Really realize the unified management of a center.

2. Intelligent audio and video monitoring in prison (PE50 10 video intelligent analysis module)

According to the requirements, it is necessary to carry out all-round video surveillance of the prison and set up audio intercom devices to facilitate the prisoners to communicate with the supervision center and the police on duty. In addition to open intercom and riot control measures, others require secret installation.

Working principle: According to the noise of cell activity, we can record and analyze it, and at the same time, we can monitor the sound information inside the cell when switching monitoring. When fighting and other events occur, the abnormal sound detected by the audio probe will be improved. We have two ways to realize the function of sound detection and alarm. In the first case, the sound wave threshold can be set on the front-end audio probe. When it exceeds a certain decibel, the output switch value drives the local intercom equipment and automatically uploads it to the monitoring host of the management center. After receiving the signal, the center will automatically switch between video information and audio information to realize direct monitoring, shouting, alarm and other direct operations. The second scheme: after the audio signal transmitted to the back end is connected to DVR, the sound threshold can be set. When it exceeds the set value, the management software can automatically switch between video information and audio information, and can directly call for warning. If the digital camera mode is adopted, first input the audio probe into the network camera, set the threshold on the network camera, or set the alarm threshold on the back-end streaming media server.

As shown in the figure:

(ambient sound monitoring is normal) (abnormal ambient sound monitoring will pop up automatically)

As shown above, intelligent analysis of indoor scenes can realize information such as crowd density and abnormal behavior, start early warning measures, notify supervisors of real-time information, automatically pop up pictures, and automatically link IP broadcasting equipment to play early warning voice information.

The unified access of all information to the monitoring private network is related to the system linkage and unified management of PE90FH high-definition digital matrix.

3, perimeter alarm and video intelligent analysis

Combined with peripheral infrared reflection, it forms a visible and invisible protection combination.

On the basis of the existing perimeter video protection, an intelligent video analysis device PE50 10 is added, which can automatically start the defense plan according to the monitoring characteristics of different time periods. The double protection of visual defense and infrared alarm defense complement each other, and the warning zone and warning zone are defined according to the characteristics of the fence warning zone.

As shown above, a defensive zone is set up within the perimeter. If you appear, wander or stay in this area, you can start early warning measures, inform the supervisor of real-time information, and automatically pop up the screen. You can also automatically link IP broadcast equipment to play early warning voice information.

4. HD entrance and exit management system

The entrance and exit adopt Red Apple HD webcam (PE8080) and automatic identification management system, which can quickly identify company vehicles and automatically record and prompt relevant information to the monitoring center. There is also a sub-control display system at the entrance guard to monitor relevant information in real time. If it is a social vehicle, the vehicle information can be automatically registered, and the license plate registration form can be automatically printed as long as the driver information and personnel information are input, thus upgrading the traditional manual registration personnel to an automatic management system with complete and real-time information.

On the basis of vehicle safety inspection, we have established a dynamic vehicle chassis scanning system, which can comprehensively scan the vehicle chassis entering and leaving the prison to prevent prohibited items from entering and leaving. After the system detects suspicious information, it automatically starts the road gate to close the vehicle driving channel and starts the system emergency plan.

5.GPS positioning tracking patrol system (PE5060 integrated management platform)

The patrol monitoring system based on GPS and GSM mobile communication network provides real-time monitoring of the position and status of patrol personnel for managers with the help of GIS electronic map, supports intercom function and video switching linkage, and tracks patrol personnel in real time in all directions without blind areas. Ensure the safety of the supervisor.

Mobile terminal is also our handheld terminal system, including GPS receiving module, communication controller and peripheral equipment.

Its structure is as shown in the figure:

Patrol system is associated with video monitoring system, voice alarm system, access control system and video intelligent analysis system to ensure comprehensive coverage and real-time management of information.

Patrol personnel locate by GPS, and send the coordinates to GPS control center through terminal equipment and GSM mobile network. The center can observe the movement track of patrol personnel on GIS map in real time through playback, call video monitoring subsystem and video access control, and view the status of personnel in real time. The patrol personnel and the personnel on duty in the monitoring room enjoy the information of detainees, and cooperate with the image superposition of each cell, so that managers can better grasp which cells have dangerous elements and need monitoring. Through voice intercom with patrol personnel, information sharing, video observation and global information display of the map, the combination of point, line and surface can dynamically understand the prisoners and their surrounding environment in real time. At the same time, cooperate with the GIS map analysis and intelligent analysis software PE50 10 to check the position of patrol personnel and management personnel online and deploy personnel in time. Take precautions against all kinds of unexpected situations such as crossing the border, invading and gathering people to fight in advance.
