A complete power video surveillance emergency system consists of six application modules of production supervision, emergency support, command and dispatch, restoration and reconstruction, public communication and supervision and management and data middleware of the power generation emergency system, which is related to the regulation of daily power production process Is the production of regulatory application module, when an emergency occurs, depending on the level of emergency will be used to different 6 large application modules. Production supervision module is the basis of the whole system.
At present, there are two kinds of challenges in power industry safety production: one is how to collect, store and supervise real-time information, preventive practices, and site visits of power production inspections, overhauls and operations timely and accurately in the daily power production management process Sexual violation and misoperation; and the other is how to obtain accurate and timely emergency information timely and comprehensively according to the pre-formulated plan in the event of emergencies such as man-made damage or natural disasters in power production The command and dispatch, to minimize the damage caused by emergencies.
To solve these two problems, it is necessary to carry out a full range of "process real-time management and supervision" on the production, routine maintenance, dispatch and production under emergency conditions; real-time recording of the dynamic process of construction site operation so that all event information can be timely and detailed Record; through the dynamic video and audio so that managers can fully understand the real-time images of the job site for the first time, to provide full data support for the management of decision-making work to improve production and repair, repair failure response speed; through the historical events statistics The analysis provides technical support for production management and comprehensively and effectively improves the rationality of production work. At the same time, the emergency command system for power production needs a variety of technical means, such as wireless transmission technology, satellite transmission technology, satellite positioning technology, geographic information technology and computer information technology. The advanced emergency management command concept can lead the leading group in conducting The center real-time understanding of the scene of the accident occurred quickly and comprehensively collected information related to accident handling, such as the distribution of repair power, the supply of emergency supplies, the protection of key power supply units. The leading group can communicate in real time with the command team and incident handling personnel at the accident site, give direct decision-making opinions to the on-site command team, and inform important information related to on-site accident handling. The on-site command team and incident handling personnel can also provide real-time emergency management The leading group of the command center reports the scene.
From the system model and the power system development of other systems, the power industry tends to adopt B / S mode, installation and upgrade more convenient. There are mainly two kinds of architectures adopted by the system: NET architecture and J2EEJ architecture. Two architectures have their advantages and disadvantages, due to the maintenance of more convenient, users are more willing to accept the NET architecture. Considering the integration with other systems in the power industry, adopting SOA architecture in power video surveillance emergency system is particularly important. In order to improve development efficiency and system scalability and increase business flexibility, the use of various middleware in power video surveillance emergency system will be more and more.
In recent years, the power industry began to pilot video surveillance emergency system, of which Jingzhou Power video surveillance emergency system is more prominent, it is based on the emergency command system of power production emergency command center as the core, management of distribution network video surveillance system, substation Single-soldier system, unified communications system, video intelligent patrol system, and with the existing power grid SCADA real-time monitoring system, power supply facilities, real-time positioning of personnel and equipment GPS / GIS positioning system, distribution network with real-time fault information distribution Taiwan area online monitoring system, command and distribution network fault handling distribution network fault information management system, spare parts and equipment management system and other systems to achieve information sharing. The main features are: real-time video surveillance as the core, the establishment of a relatively complete power production inspection, maintenance, operation of real-time regulatory business processes to avoid habitual violations and misuse occurred; the electronic plan as the core, established A set of perfect emergency procedures for power production emergency procedures to ensure the correctness of emergency response.
