The thermal power plant security system covers a large number of subsystems. The system consists of a video surveillance system, an entrance and exit control system, a parking garage management system, an intrusion alarm system, and an electronic patrol system. According to our investigation of some thermal power plants and the exchanges with design institutes, we found that most thermal power plants only deploy video surveillance systems, intrusion alarm systems, and access control systems (part of the entrance and exit control systems), and existing systems have not been effectively applied. In terms of system functions, resource sharing, and business integration, there are various aspects that need to be improved.
Background and challenge
Since the reform and opening up, with the rapid development of the national economy, China's power industry has also achieved rapid growth. As of the end of 2013, the total installed capacity of China's existing generating units accounted for 69% of the total thermal power, hydropower accounted for 22%, and other power generation methods accounted for 9%. Thermal power generation is still the main mode of power generation in China and is the main force for power production.
In recent years, international and domestic terrorist activities have been active, and major vicious terrorist incidents have occurred frequently. Reliable power supply is related to the stability of society. As the main power production enterprise, thermal power plants can easily become the target of terrorist attacks and belong to the key targets. Counter-terrorism has heavy tasks and great responsibilities. Combining the domestic situation of anti-terrorism in recent years, in order to effectively strengthen the standardization and standardization of safety precautions for power facilities, the Ministry of Energy and the National Energy Administration studied and formulated the “Risk Rating and Security Requirements for Power Facilities†(GA1089-2013, hereinafter referred to as “Security Requirementsâ€). The "Security Requirements" was issued by the Ministry on September 30, 2013 and implemented on November 1, 2013.
The thermal power plant security system covers a large number of subsystems. The system consists of a video surveillance system, an entrance and exit control system, a parking garage management system, an intrusion alarm system, and an electronic patrol system. According to our investigation of some thermal power plants and the exchanges with design institutes, we found that most thermal power plants only deploy video surveillance systems, intrusion alarm systems, and access control systems (part of the entrance and exit control systems), and existing systems have not been effectively applied. As a result, there are various areas that need to be improved in system functions, resource sharing, and business integration.
1) The current video surveillance system has a low utilization rate and a low degree of intelligence, and there are still monitoring blind spots in some key areas;
Each system has its own division of functions in terms of function realization. Under normal circumstances, it is necessary to install configuration software and operating software, resulting in redundant software and hardware in the equipment room.
2) The power plant does not have an integrated security management system and cannot implement unified monitoring of equipment, which increases system operation and maintenance costs and security risks;
3) Without a unified database, information sharing and system data management and maintenance cannot be implemented internally;
4) System linkage is mostly limited to hardware linkage, increasing the complexity of implementation and maintenance;
5) The global plan cannot be configured to achieve service optimization under a unified platform.
6) The system administrator needs to be familiar with a variety of management clients with different styles and control logics, which can easily result in business inefficiency or work omissions;
7) It is impossible to remotely view the operating data of the entire system. Most of the system information does not leave the management room, which is not conducive to upper management.
In view of the above analysis, the existing thermal power plant integrated security management urgently needs a unified management platform to integrate various system resources, optimize business management, and reduce investment costs and operation and maintenance costs.
The goal of building
As the core link of anti-terrorism prevention in thermal power plants, the safety and security system is of great importance. In order to meet the security management of the thermal power plant by the security control center, a modern management system adapted to thermal power plants must be established. The system is supported by modern information technology, network interconnection, information resources sharing, and complete application functions. It mainly achieves the following goals: unified integration of the subsystems, digitization and intelligence, a unified management platform, an open architecture, and support for high-definition monitoring.
solution
The overall topology of the system is shown in the figure below:
The thermal power plant security system consists of front-end systems, transmission networks, and central systems, which are indispensable to each other.
In the process of system design, in addition to complying with relevant standards for power safety precautions, appropriate technological innovations will be implemented. Hikvision's thermal power plant security system can achieve the following functions:
1) High-definition video surveillance: Fully access 1080P and above high-definition cameras to enhance video quality and security levels to meet the needs of detail monitoring (face, vehicle characteristics), support high-definition video storage;
2) Intelligent analysis and identification: behavior analysis, face recognition, license plate recognition;
3) Security system integration: The integration of subsystems such as video surveillance, access control management, visitor management, on-line inspection, parking management, and intrusion alarms is implemented. Each subsystem is linked according to a preplan;
4) Three-dimensional supervision mode: realize the vertical supervision of the front-end and security control center. The fixed network uses C/S and B/S methods for access. The mobile network is supervised by hand-held terminals (mobile phones, tablets, etc.);
5) System operation and maintenance management: IT infrastructure management, video quality diagnosis, bandwidth optimization and control, asset management, log management.
Highlights of the project
1. Comprehensive integration of technical protection systems
The system can integrate all safety basic technical protection systems in thermal power plants, including video surveillance systems, entrance and exit control systems, intrusion alarm systems, patrol systems, etc., and integrate applications to achieve information and data interaction and alarm linkage response across systems. The plan is automatically implemented to comprehensively improve the overall warning and defense capabilities of the power station.
2, multi-smart technology integration application
The system uses a variety of intelligent analysis technologies to analyze frame by frame the live video stream and video playback video stream, automatically filtering useless video images, allowing security personnel to focus on "value" videos. The application of intelligent technology is equivalent to deploying "never tired" security to the power station and changing passive monitoring to active monitoring to achieve the purpose of "pre-emptive, incidental, and post-mortem analysis" of power station security incidents.
3, perfect operation and maintenance management mechanism
The system can realize various types of equipment and resources such as video equipment, alarm equipment, access control equipment, intercom equipment, patrol equipment, network equipment, storage equipment, application servers, middleware systems, database systems, business application systems, and machine room power environment. Real-time monitoring and early warning, and standardized management of the process of operation and maintenance, the management of electronic data, standardized management process, so as to build a unified, complete and proactive process of operation and maintenance, standardized services and centralized management for the entire network operating environment, Comprehensively improve operation and maintenance management capabilities.
