In firefighting and rescue work, efficient fire communication and command are crucial. In order to improve work efficiency, it is necessary to combine 5G communication technology with fire communication and command to improve the effectiveness and quality of command.
2. 5G communication technology and fire communication command
1. Overview of 5G communication technology
As a new generation of broadband mobile communication technology, 5G communication technology has the characteristics of high speed, low latency and large connection, and is widely used in all walks of life. In fire communication command, the use of 5G technology can greatly improve work efficiency and realize the interconnection between man, machine and object, providing support for the efficient implementation of fire fighting and rescue tasks. The low latency and fast response speed of 5G network make it widely used in industries with extremely high requirements for latency and reliability, such as industrial control, remote command and autonomous driving. In fire communication command, the requirements of accuracy, speed and uninterruptedness make the characteristics of 5G technology of great significance. By using 5G technology, real-time video transmission, real-time data exchange and instant command transmission of fire command can be realized, improving the accuracy and time responsiveness of command decision-making. In addition, 5G technology can also realize the interconnection between man, machine and object, and effectively integrate various communication connections. This feature can be applied to fields such as smart cities, smart homes and environmental monitoring, and can also be applied to the field of fire communication command. By realizing high interconnection between different objects, the effectiveness of fire rescue work can be improved, and close cooperation and information exchange between the command center and on-site personnel can be promoted.
2. Application of 5G communication technology in fire communication command
The high speed and low latency characteristics of 5G communication technology provide the fire command center with the ability to understand all kinds of data information at the fire rescue site and the surrounding area in real time. Through 5G communication technology, the fire command center can monitor the physical functions of rescue personnel in real time and obtain the environmental conditions of the rescue site, so as to accurately issue instructions and carry out fire fighting and rescue work. In addition, 5G technology can also realize remote control of some equipment for reconnaissance or fire fighting and rescue, and realize the interconnection between man, machine and things. This connectivity plays an important role in reducing the risks of front-line combat personnel and improving operational safety, and helps to promote the professional development of fire fighting and rescue work.
With the rapid development of social economy, the application of 5G communication technology in firefighting and rescue will become more and more extensive. The firefighting communication command system built based on 5G technology can strengthen the communication and coordination between firefighting and rescue personnel, improve the efficiency of teamwork, and also improve the firefighting and rescue efficiency of the firefighting team. In addition, building a firefighting communication system with a wide coverage will help to effectively respond to various disasters and accidents.
3. Current status of fire communication command in my country
1. Fire communication and command equipment is not compatible
At present, the fire department has a variety of communication equipment, and the standards and communication protocols used are also different, which leads to compatibility issues between equipment. In the context of the development of fire informationization, in order to promote the visualization of fire communication command and strengthen the application of big data collection and cloud computing analysis in command, the fire command center needs to integrate various communication equipment and improve its compatibility to enhance the ability to assist decision-making. At the same time, firefighting and rescue tasks in some special scenarios have high functional requirements for communication equipment. The limitations of traditional communication technology may lead to poor on-site communication and affect fire command.
2. The fire communication and command system is developing slowly
After the reform of the system and mechanism, firefighting work faces the functions of all types of disasters and large-scale emergency response, and the tasks are gradually increasing and becoming more and more arduous. In firefighting and rescue work, various disaster accident rescues often pose a huge threat to firefighters, and may even cause casualties. Therefore, the firefighting communication command system needs to further strengthen the information exchange between the command center and the firefighting and rescue site to help the on-site firefighters to effectively carry out firefighting and rescue work, which is also an important basis for ensuring the safety of firefighters. However, the development of the firefighting communication command system in many areas of my country is relatively slow, and a good front-to-back communication command system has not yet been established. Especially in special scenes such as high, ground, large, and chemical, there are various difficulties. The lack of a good communication command system construction may cause firefighters to delay the best time for firefighting and rescue, and even increase unsafe factors for firefighters. In addition, the construction of the communication command system in some areas is very weak, and it is impossible to scientifically judge the development trend of the disaster, and it is impossible to understand the unsafe factors that may occur, which is also easy to cause confusion in firefighting communication command.
3. Communication technology has defects
At present, there are some problems with fire communication, such as short communication distance, limited network frequency, poor anti-interference ability, etc. In some special environments, such as high-rise buildings, underground spaces, large-span spaces and chemical sites, the communication signal will drop significantly and the communication distance will be limited. In order to solve these problems, some fire rescue teams have begun to popularize the use of digital public network signals or digital trunking intercom systems to enhance communication coverage and increase communication distance. However, these systems rely on areas covered by public networks or trunking networks, resulting in unsatisfactory results in remote mountainous areas with poor networks.
4. Difficulties in applying 5G communication technology in fire communication command
1. Failure to unify protocol standards
Judging from the existing fire communication equipment, there are problems such as inconsistent equipment brands, inconsistent models, and inconsistent operating protocols among various fire rescue teams, which leads to the inability of effective compatibility and common use between equipment. Although 5G communication technology has matured and is widely used in various fields, its application in fire communication command is still not popular. Although 5G communication technology can provide faster communication speeds and more stable connections, it cannot solve the compatibility problems between different systems. Therefore, there is an information communication isolation phenomenon between the existing communication command equipment, which is not conducive to the development of on-site fire communication command work, and cannot effectively promote the construction of fire communication informatization.
2. Failure to standardize 5G construction progress
At present, most first-tier cities and some second-tier cities in my country have introduced 5G communication systems and combined them with other information systems, which has brought great convenience to fire command and dispatch. However, the development of my country’s eastern and western regions is unbalanced, and there are also differences in development between first-tier and second-tier cities, which has led to slow progress in 5G construction in many third-tier and fourth-tier cities, and the corresponding 5G technology supporting facilities are also insufficient, which has brought inconvenience to the development of fire communication command.
3. Immature hardware and software supporting facilities
With the reform of various departments towards information technology, the fire command center also needs to carry out the corresponding information construction, and use scientific and technological means to improve the command efficiency and decision-making ability.In this process, a strong communication network is indispensable, and 5G communication technology can meet the needs of high-speed and stable communication.However, the hardware and front-end equipment matching 5G communication technology have not yet been developed and promoted on a large scale.This means that the promotion and development of 5G-based fire command equipment and related supporting software still need to be further enhanced.Only when these supporting facilities are fully equipped can the high-speed advantage of 5G communication technology be fully utilized.
5. Application strategy of 5G communication technology in fire communication command
1. Establishing a sound communication and command system
In order to give full play to the role of 5G communication technology in fire communication command, the fire communication department can do the following:
① Formulate fire communication standards, combine them with 5G specifications, clarify fire communication data collection standards and technical research and development standards, avoid technical conflicts and duplication of construction, and thus save precious funds.
② Build a high-quality data collection system to collect and organize data related to fire communications to provide support for command and decision-making.
③ Build an emergency communication network security system, set up a scientific information system, and achieve comprehensive coverage of communication signals. Combined with the characteristics of all-disaster and large-scale emergency firefighting and rescue tasks, based on geographical advantages, establish a cross-regional emergency communication security team and form a complete emergency communication network security system.
④ Strengthen cooperation with local governments, work closely with local governments, and strive for the support of government departments when building a scientific communication command system. For example, the fire communication department can strengthen strategic cooperation with various communication units, and make full use of the technical advantages of communication units to provide technical support for the fire department to build a scientific communication command system.
2. Strengthening on-site communication, command and data transmission
In the context of the rapid development of information technology today, the application of 5G communication technology can realize the real-time transmission of information, which is particularly important for the fire communication command center. By using 5G communication technology, the fire command center can monitor various environmental data at the disaster site in real time. Compared with the existing communication system, due to the limitation of broadband transmission speed, data transmission is relatively limited, and it is difficult to achieve real-time and efficient transmission of multiple data. However, with the advent of the 5G era, these limitations will be significantly improved, and data transmission will be more timely and efficient.
In the 5G era, the fire command center can transmit on-site images through image transmission equipment, use detection equipment to instantly monitor toxic gases in the air, and receive various data sent by IoT devices in real time. In addition, the fire communication command center can also track the status of personnel in real time through 5G, and understand important information such as the specific location, heart rate, and breathing pressure of rescue personnel. Through real-time transmission and feedback of data, the command center can immediately respond to the situation and provide accurate assistance for fire fighting and rescue decisions.
3. Create a new communication command model
With the rapid popularization of 5G communication technology and the support of various communication equipment, the fire communication command center can create a new communication command mode. The command center can better assist decision-making and command by analyzing the various data transmitted by personnel at the disaster site, and play a greater role in performing fire fighting and rescue tasks. This will help to build a complete command system and improve the efficiency of fire fighting and rescue tasks. With the help of 5G communication technology, the detection function can be combined with artificial intelligence technology and integrated into communication equipment. Through modern communication technology, the effectiveness of fire fighting and rescue can be improved, so that the command center can make decisions and commands more accurately. In addition, with the development of technology, with the support of 5G communication technology, human-machine-object interconnection technology can enable firefighters to remotely control equipment for fire fighting and rescue. At special disaster sites, this will reduce the risks of front-line combat personnel and improve the safety and quality of fire fighting and rescue tasks.
6. Prospects for the application of 5G communication technology in fire communication command
(I). Standardizing the management of fire rescue teams
In order to standardize the management of fire rescue teams and establish a highly professional team, emphasize discipline and strict daily management system, 5G communication technology can be used for digital management. With the maturity of communication technology and the widespread application of artificial intelligence technology and digital sensors, the combination of 5G communication technology and digital management can comprehensively improve the management level of the team. With the support of 5G communication technology, various vehicles of the fire rescue team can be managed in a unified manner. Through on-board sensors, the status of the vehicle can be understood in real time and effectively controlled through the 5G platform. This includes vehicle fuel management, maintenance management, and operation trajectory data. By using 5G communication technology, the management of duty and guard duty can also be strengthened. Through digital monitoring and sensors, the entire camp can be fully supervised, combined with digital artificial intelligence analysis methods, to realize the alarm of risk points, and through the wireless sensor integrated intelligent control platform, high-definition face recognition is used to complete on-site authorization, so as to achieve effective control of internal and external personnel.
(II) Serving the firefighting and rescue teams
The application of 5G communication technology can play an important role in firefighting and rescue tasks, especially in building unmanned firefighting and rescue systems. The human-machine-object interconnection built with 5G technology can achieve many advantages in firefighting and rescue. For example, firefighters can use drones to conduct fire reconnaissance and select the best firefighting and rescue plan. By using drones equipped with different sensors to transmit data from the disaster site in real time, a scientific assessment of the fire scene can be completed in the shortest time.
5G communication technology can also realize the intelligent improvement of firefighters’ life safety equipment. By embedding 5G communication chips in the equipment, the vital signs of firefighters and the operating status of the equipment can be monitored in real time, and firefighters can be notified to evacuate when necessary. For example, the pressure of air respirators can be monitored through IoT technology, the data of high-temperature areas on site can be collected through infrared sensing equipment, and the pulse frequency and other information of firefighters can be understood by using TENG electrocardiogram sensors. Relying on 5G technology, the fire brigade can also establish an efficient communication network to optimize the transmission of on-site rescue commands. Through high-definition and low-latency image transmission, the communication command function can be brought into play to improve the safety and reliability of the entire firefighting and rescue process.
(III) Simulate real firefighting and rescue scenes
Through the application of 5G communication technology and virtual reality (VR) technology, the real scene of fire fighting and rescue can be simulated, providing new firefighters with a more realistic training experience. Traditional fire fighting and rescue training usually relies on verbal explanations and on-site videos, which cannot provide sufficient actual combat simulation. Through 5G+VR technology, systematic training can be carried out according to different scenarios and different technical and tactical characteristics, greatly shortening the growth process of new firefighters and enhancing the training effect. VR technology creates a realistic three-dimensional sensory experience through computers and other equipment, allowing firefighters to experience the fire fighting and rescue scene in person. In the simulated fire fighting and rescue scene, firefighters can experience the real tense atmosphere, cope with various different fire fighting and rescue difficulties, and even train under special conditions such as dark environments and high temperature environments to overcome psychological barriers. In other words, through the application of 5G+VR technology, new firefighters can more realistically feel the tense atmosphere at the fire fighting and rescue scene and improve their ability to cope with various situations. This training model can not only accelerate the growth of new firefighters, but also enhance the training effect, so that they can be comprehensively improved in many aspects such as technology, psychology and command quality.
7. Conclusion
In the ever-evolving technological progress and innovation, 5G communication technology plays an increasingly important role in fire communication and command. By establishing a sound communication system, strengthening data transmission, creating a new command system, and improving business models, 5G communication technology provides fire rescue departments with more powerful tools and support, improving communication efficiency, command decision-making capabilities, and rescue effectiveness. In the future, with the continuous development of technology, it is believed that 5G communication technology will play a greater role in the field of firefighting, and make greater contributions to protecting the lives of people and reducing property losses. The fire department will continue to actively explore and apply new technologies, continuously improve its own capabilities, and contribute to the safety and stability of society.
