    The key technologies that help the development of intelligent fire protection mainly include the following ten types:

1. Radio frequency identification

    RFID (radio frequency identification) technology, also known as radio frequency identification, is a communication technology, which can identify specific targets and read and write relevant data through radio signals without establishing mechanical or optical contact between the identification system and specific targets.

2. Wireless sensing

    Wireless sensor technology has long been used in the field of fire protection, but its early function was relatively single, using point-to-point transmission. With the continuous progress and development of science and technology, sensor networks have the comprehensive processing ability of multiple information signals at the same time.

    Radio frequency identification and wireless sensing are both Internet of things technologies, which are used to collect the alarm information of each automatic fire alarm host, so as to realize the remote monitoring of fire protection.

    The smart sensing terminal supported by radio frequency identification and wireless sensing technology overcomes the characteristics that the traditional independent alarm and monitor can not be connected to the network and wiring, can be installed independently and connected to the wireless network, and greatly improves the fire construction efficiency and intelligent level.

3. Internet of things

    The Internet of things refers to a huge network formed by the combination of any object or process that needs monitoring, connection and interaction in real time through various information sensing devices.

    Firstly, the intelligent fire IOT constitutes the basic unit of urban fire IOT through the wireless sensing devices such as smoke detector, temperature detector, manual alarm button and combustible gas detector deployed in the wide area, combined with the water consumption and water pressure monitoring of fire hydrant and the liquid level monitoring function of fire pool.

    At the same time, taking wireless communication technologies such as Lora, Nb IOT and WiFi as carriers and using technology applications such as big data and cloud computing, the data such as the location distribution, equipment status and fire monitoring of the basic units of the Internet of things are connected to the cloud for integrated analysis, and finally presented to residents, property and fire authorities through app mobile client and web page, so as to provide intelligent Information means.

    The core of the first step of intelligent fire protection is to establish an Internet of things Management Center to determine the data and information required for intelligent fire protection. As Ding Hongjun, chief engineer of Shenyang Fire Research Institute of the Ministry of public security and national fire electronic product testing center, said, "fire protection in five years must be the world of the Internet of things!"

4. Big data

    Big data refers to a data set that cannot be captured, managed and processed by conventional software tools within a certain time range. It is a massive, high growth rate and diversified information asset that requires a new processing mode to have stronger decision-making power, insight and discovery power and process optimization ability.

    Big data is meaningless. The key technology of intelligent fire fighting is not only the analysis of big data, but also the key technology of machine in-depth learning. Its focus is on prediction. Using the technology of data exploration, we can find the correlation or experience that is not easy to find in massive data, so as to quickly accumulate experience values and make accurate prediction and decision-making.

    It has the leading power in the possession, control, analysis and processing of massive data, promotes the transformation of decision-making mechanism from "business driven" to "data prediction", the transformation of management mechanism from "watching and guarding" to "prediction and early warning", the transformation of combat mechanism from "empiricism" to "scientific decision-making and intelligent scheduling", and transforms big data optimization into combat effectiveness advantage, Perhaps it will become the key to the victory of "intelligent fire fighting".

5. Cloud computing

    Cloud computing is the increase, use and delivery mode of Internet-based related services. It usually involves providing dynamic, scalable and often virtualized resources through the Internet.

    The intelligent fire cloud platform continues to integrate the leading capabilities such as big data and artificial intelligence accumulated in the development process, provide cloud solutions for the fire industry and help the fire industry realize digital transformation.

    In the future development of cloud computing, because massive data is stored and calculated in the cloud, network security will play a key role in big data and cloud computing, and it is also an important support for the development of intelligent fire fighting.

6. Mobile Internet

    Mobile Internet is the combination of mobile communication and Internet into one. It refers to the general name of activities that combine and practice Internet technology, platform, business model and application with mobile communication technology.

    The application of mobile Internet in intelligent fire protection is mainly to develop mobile terminal systems such as mobile phone AAP, realize dynamic monitoring and three-dimensional display of the fire safety status of networked units, and comprehensively improve the fire safety management level and fire supervision and law enforcement efficiency of social units.

7. Geographic Information System

    Geographic Information System (GIS) is a computer spatial or spatiotemporal information system that expresses, obtains, processes, manages, analyzes and applies the characteristic elements of geospatial entities and phenomena.

    Adopting technologies such as two-dimensional pictures, panoramic photos, three-dimensional modeling and UAV tilt photography based on GIS can prepare digital plans for intelligent fire protection and provide strong support for the realization of "one picture" visualization strategy.

8. Virtual reality

    Virtual reality technology (VR) is a computer simulation system that can create and experience the virtual world. It uses the computer to generate a simulation environment. It is a system simulation of multi-source information fusion, interactive three-dimensional dynamic scene and entity behavior, so that users can immerse themselves in the environment.

    Through virtual reality technology, it can realize the functions of force query, geographic information measurement, combat deployment plotting, auxiliary individual positioning and so on, and assist the commander to carry out planned command and on-the-spot command; In the room, familiarization exercises, battle example replay, battle command deduction and three-dimensional scene display can be carried out to assist commanders and fighters in business learning.

    Such as fire safety education VR platform, VR fire training system, VR panoramic video monitoring, etc., are the specific achievements of VR application to intelligent fire protection.

9. Artificial intelligence

    Artificial intelligence (AI) is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence.

    The application of artificial intelligence technology to the fire protection industry has derived many new intelligent machines that can respond in a similar way to human intelligence. These scientific and technological products brought by artificial intelligence will be important equipment for intelligent fire protection.

    For example, the University of Michigan released Cassie robots that can walk through the fire, the first batch of special fire robots in Hangzhou have officially entered the fire force, and many UAVs have come out, which will help firefighters carry out fire detection and rescue in extreme environments.

10. Blockchain

    Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and encryption algorithm. Since 2018, in order to control the occurrence of disasters and accidents and improve the construction ability of responsible government, the accountability system has been continuously deepened in the field of public safety, and the accountability in the field of fire safety has become more and more important.

    Blockchain technology can obtain data flow, and its integration with intelligent fire protection can better connect all fire services, improve the safety and transparency of fire protection, and provide technical and data support for identifying the responsible subject of fire accident crime.
