Firefighting equipment information: What is smart firefighting?
(1) Intelligent fire protection background
In April 2017, the work safety committee of the State Council issued the notice on the comprehensive treatment of electrical fire (No. 4, 2017), which requires that the comprehensive treatment of electrical fire should be carried out nationwide in three years, so as to significantly improve the quality of electrical products, the quality of electrical design and construction of construction projects, the safety level of power consumption and maintenance of social units, and the number of electrical fire accidents in the country.
In October of the same year, the fire bureau of the Ministry of Public Security issued the opinions of guidance teachers on the comprehensive development of students and the promotion of "intelligent fire protection" construction (GX [2017] No. 297). The opinions can require that by the end of 2018, the analysis cities at or above the prefecture level should establish the remote monitoring information system of the fire Internet of things technology. At present, the cities in China that have realized the establishment of the fire Internet of things application system, More than 70% of high-risk fire units and high-rise buildings with automatic fire-fighting infrastructure will access the network system for building design by the end of 2018. The public security fire brigades of all provinces, autonomous regions and municipalities directly under the central government have created an "upgraded version" of the urban fire remote monitoring software system, which is connected to the entire electrical fire monitoring system or device to monitor the leakage current, cable temperature and other conditions in a real-time environment; Research and development of smart phone app system, dynamic process monitoring, three-dimensional display of the safe operation status of the fire personnel of the related units, comprehensive quality improvement of the fire safety education and management level of economic and social practice units and the efficiency of fire supervision and administrative law enforcement.
(2) Overview of intelligent fire protection
"Intelligent fire protection" is to use new technologies such as Internet of things, artificial intelligence, virtual reality and mobile Internet + to cooperate with big data cloud computing platform, fire protection intelligence research and professional application to realize intelligent urban fire protection, improve information transmission efficiency, ensure the integrity of fire protection facilities, improve law enforcement management effect, enhance rescue capability and reduce fire losses.
The fire intelligent IOT system is composed of a transparent transmission module of the fire host, intelligent power consumption, intelligent fire water sensing terminals (including fire pipeline pressure and fire reservoir water level detection), intelligent smoke sensing, web application terminals, and mobile phone app terminals. The Internet of things technology is applied to realize the connection between the intelligent alarm terminal and the web platform, to grasp the terminal points of the fire host, power line and fire water system in real time, and to deal with hidden dangers in time. Minimize fire hazards.
Intelligent fire fighting is an advanced problem-solving solution. Compared with traditional building fire fighting, it pays attention to breaking through the information and data islands between various systems, improving its own perception and early warning management ability and emergency command intelligence development ability. Through early detection and faster treatment, the fire risk and influencing factors will be minimized.
In essence, intelligent fire fighting is not only the networking of fire equipment data and platforms, but also the application of high-tech technologies such as Internet of things, cloud computing, artificial intelligence and blockchain. To achieve environmental awareness, behavior management, process control, intelligent judgment, scientific command and other objectives.
（3） Role of intelligent fire fighting
Compared with Chinese traditional building fire fighting, smart city fire fighting makes fire fighting work more automatic, intelligent, systematic and refined by using Internet of things, big data, artificial intelligence and other technologies. The main problems of its "wisdom" are reflected in the four development aspects of intelligent prevention and control, intelligent enterprise management, intelligent operation and intelligent command.
Intelligent prevention and control: abnormal automatic alarm, improve information transmission efficiency.
The intelligent fire fighting system integrates high-tech intelligent terminals and sensing devices, and uses Internet of things technology and big data cloud platform. Once danger and abnormality are found, the system will automatically notify the user through the terminal equipment for timely treatment. The passive detection of danger is the active monitoring and early warning to prevent the main danger from being controlled in the bud.
Wisdom: systematic daily management to ensure the integrity of fire-fighting facilities.
In traditional fire fighting, the management of fire safety facilities depends on manual work. The common formalism is that relevant staff can analyze and check the equipment, and then register the relevant research. In real life, due to the inertia of people and the lack of a good supervision mechanism of enterprises, the relevant data and information of fire-fighting infrastructure equipment are inaccurate. Once a fire occurs, the current information may not provide some help, or even mislead the field operations.
The intelligent fire fighting system uses the Internet of things and infrared sensing technology to record the position and status of the current fire fighting equipment. If the system is damaged, it can report for repair to better ensure the integrity of the fire fighting equipment. Provide accurate equipment information.
Intelligent Warfare: Based on real-time dynamic data, more efficient and accurate warfare.
Through video monitoring system, Internet of things data., Intelligent fire fighting can realize the integration of on-site personnel, geographical location and real-time data., And dynamically update them in real time. With the help of these refined data, on-site combatants can achieve accurate operations and improve rescue efficiency.
Intelligent command: carry out visual dynamic analysis image on site to realize intelligent resource scheduling.
Real time transmission of intelligent fire scene images, one image connecting all systems and data, meeting the requirements of visualization and dynamic command. Realize real-time intelligent dispatching of fire rescue personnel, fire engines, fire equipment, fire water sources and other resources to help put out the fire at the fastest speed and ensure the safety of personnel and property.
To sum up, intelligent fire protection is to realize automation, data, accuracy and intelligence from prevention and control to on-site dispatching, and from fire protection to safety protection, so that the public can get comprehensive, efficient and intelligent safety protection.
(4) Composition of intelligent fire fighting system
The intelligent fire protection system is composed of front-end data acquisition technology equipment, Internet of things information transmission control system, management work platform, application client and back-end server group.
