1. Introduction
Generally speaking, emergency communications mainly include the following aspects: monitoring and communication before an accident occurs, communication in an emergency, and communication in the process of waiting for rescue after an emergency occurs. After a fire occurs, the fire brigade will face challenges and practical needs in the process of carrying out the later rescue work. Therefore, in the actual rescue work, the role of fire emergency communication is more important. In order to improve the effectiveness of fire emergency command work, it is necessary to establish and improve the fire emergency communication system, and by combining computer technology and cloud platforms, give full play to the role of digital microwave communication in fire emergency communication to ensure the smooth development of fire rescue work.
2. Concept and characteristics of digital microwave communication
(I). Concept
The propagation mode of microwave communication is relatively stable and is less affected by external factors and interference. Although it may be affected by factors such as terrain and weather, reflection and refraction may occur, resulting in signal propagation distortion. However, in the case of natural disasters such as major floods and earthquakes, microwave communication has the best effect and will not be affected by the disaster. Therefore, it has significant advantages in large-scale disaster relief processes.
(II) Characteristics
An analysis of the relevant technical characteristics of digital microwave communication can be roughly summarized into the following aspects.
First, the communication effect is relatively good. This is because in the field of traditional communication technology, in order to ensure that the communication signal can be transmitted most effectively, it is generally believed that traditional communication technology uses the same signal channel mode used by multipath and multi-channel signals. Although this can ensure the effective transmission of signals to a certain extent, there is a high possibility that the signals will interfere with each other, resulting in poor communication quality. However, digital microwave communication technology can use time slot positions to separate transmission signals, that is, the same signal channel can separate many signals. This method can better ensure the actual effect of communication signals in the propagation process, save unnecessary resource consumption, and effectively reduce the mutual interference between resource signals. At the same time, digital microwave communication technology can also be used for wireless transmission through microwave channels in actual application, which can avoid problems in the face of complex geographical conditions and interference conditions, and improve communication effects.
Second, it has better confidentiality. This is because in the process of using digital microwave communication technology to carry out signal transmission, the signal transmission method used is a digital signal, which shows that it has stronger security and confidentiality characteristics. Compared with traditional communication technology, digital microwave communication technology can enhance the security of the transmission process by digital encryption, and set up corresponding anti-interference circuits on the transceiver equipment, and set specific confidentiality levels according to the confidentiality of the information, which can indeed meet the basic requirements for improving confidentiality.
Third, the networking method is relatively more convenient and faster. In the specific application process of digital microwave communication technology, the main method adopted is to use digital information as the transmission mode. Therefore, under the premise of the continuous development of current information technology and computer science and technology, a more complete digital communication network can be formed by using it, and the advantages of modern information technology can also be used to effectively improve the overall quality of information exchange, which is the key to improving information transmission efficiency.
Fourth, the volume of the equipment itself is relatively light, and the power it consumes is also lower than that of traditional equipment. The reason is that most of the equipment is composed of integrated circuits, so the volume is relatively small, the power consumption is relatively small, and it is more in line with the actual requirements of fire emergency communication support work. In addition, from the advantages of digital microwave communication technology itself, its anti-interference ability is also significantly better, which can ensure that in the later application process, the network power is continuously reduced, the signal transmission effect is enhanced, and the transmission efficiency is improved.
3. The practical significance of applying digital microwave communication in fire emergency communication support
1. It is conducive to ensuring stable communication
The application of digital microwave communication in the process of fire emergency communication support is more conducive to ensuring the stability of communication. This is because when the communication frequency exceeds 100MHZ, various natural factors often have a certain degree of obstruction and interference on the communication signal. Therefore, in the face of high-frequency influence and interference, it is necessary to adopt a reasonable communication transmission method to improve the stability of signal transmission, so as to effectively ensure the security of communication. In addition, the digital microwave communication relay station can also form a new digital signal during the specific operation process, so as to avoid the negative impact on the communication itself during the actual line transmission process. Therefore, the application of digital microwave communication technology in fire emergency communication support is more secure and reliable.
2. The safety of the line is more guaranteed
It is precisely because microwave relay communication stations use a relay method to transmit information, so from the fundamental perspective of construction, creating a stable long-distance transmission target is the ultimate goal. In view of this, it is necessary to avoid the negative impact of terrain or other objective factors on signal transmission to the greatest extent possible, and combine relay stations to forward radio waves to improve the overall efficiency of signal transmission. In short, long-distance transmission can help significantly improve communication quality and avoid illegal implantation during the transmission process. Compared with traditional data transmission, it is more secure.
3. Greater flexibility in application
In the actual application process, the flexibility advantage of digital microwave communication technology is that it can effectively avoid the obstacles and influences caused by complex terrain conditions on information dissemination. Of course, in the face of some extremely special natural disasters, they may hinder signal propagation, but digital microwave technology is more flexible than other signal propagation pathways. This technology uses relay communication in the actual application process, so no matter what the terrain conditions are, it can meet the requirements of long-distance signal transmission. At the same time, digital microwave communication does not need to rely on other cables or optical fiber media in circuit settings. The starting point and end point of communication can be connected only through relay stations. Therefore, in the process of emergency rescue, the stability and flexibility of digital microwave communication are more significant.
4. Principles of digital microwave communication technology application in fire emergency communication support
In today’s society, fire emergency communication security is particularly important. In the face of emergencies such as sudden fires and accidents, timely and efficient communication systems can help firefighters respond quickly, launch rescue operations, and minimize losses. The application of digital microwave communication technology has brought new possibilities and advantages to fire emergency communication security.
First of all, the application of digital microwave communication technology in fire emergency communication support is in line with the principles of “fast, reliable, safe and efficient”. Digital microwave communication technology has the advantages of fast transmission speed, strong anti-interference ability and stable communication quality. It can quickly establish a stable communication network in a complex emergency environment to ensure the timely transmission of information. Firefighters can use digital microwave communication technology to achieve multi-party real-time calls, video transmission, data sharing and other functions, which effectively supports emergency command decision-making and improves rescue efficiency.
Secondly, the application of digital microwave communication technology can also improve the security and confidentiality of communication. Traditional analog communication has the risk of being monitored and stealing information, while digital microwave communication technology uses digital signal transmission and has encryption technology protection, which can effectively prevent information leakage and ensure the confidentiality of rescue operations. When performing tasks, firefighters can safely use digital microwave communication technology for command and dispatch to ensure the smooth progress of rescue operations.
Finally, digital microwave communication technology can also improve the coverage and stability of communication networks. Firefighting and rescue work often needs to be carried out in complex and changeable environments, such as high-rise buildings, basements, mountainous areas and other special environments. Traditional communication technology may have signal blind spots or signal interference problems. Digital microwave communication technology has strong penetration and anti-interference capabilities, can achieve a wider coverage range, ensure communication stability, and provide more reliable communication support for firefighters.
In summary, applying digital microwave communication technology to fire emergency communication support is a positive exploration and attempt. It can bring more convenience and protection to fire rescue work. With the continuous advancement and application of science and technology, we believe that fire emergency communication support will usher in a broader development space and provide stronger protection for the safety of people’s lives and property. May every call for help be responded to in a timely manner, and may every rescue be a complete success.
5. Specific application of digital microwave communication in fire emergency communication support
1. Building a Digital Microwave Image Self-Organizing Network
Generally speaking, when disasters such as fires occur, if the public network signal at the scene of the accident suddenly disappears or weakens, the fire brigade must immediately re-establish a set of network transmission images on the scene through the microwave image self-organizing network, and then build an integrated space-ground image self-organizing network to transmit the images to the command center. The command center uses a remote platform to control it. When rescuing some relatively large disasters, it can cooperate with drones to collect images and create an integrated emergency communication network system in the air, at high points and on the ground. It truly meets the requirements of long-distance and large-area network coverage. Relevant commanders can also judge the scene through the intuitive images presented, effectively optimize and adjust the rescue plan, and effectively improve the overall efficiency of the rescue.
2. Establishing a fire emergency image management system
There are many related image data required for emergency images, such as images of fire trucks, images of command posts and command vehicles, mobile network image transmission devices, satellite ground station image transmission devices, and drone aerial photography devices. Through the integration of computer and cloud platform resources, a complete emergency image management system can be built, laying the foundation for the subsequent fire emergency communication support work.
3. Improving the application effect of wireless trunking communication by optimizing information technology
Under the current new situation, the development of fire rescue is inseparable from the construction of fire emergency support system. In the information age, the construction and improvement of emergency communication system is the basic guarantee for the smooth development of fire rescue work. However, with the widespread application of wireless cluster communication technology, the traditional fire emergency communication system has exposed many shortcomings when dealing with complex environments, such as equipment prone to failure and low system security. Therefore, it is necessary to strengthen the information technology improvement strategy, strengthen the construction of wireless cluster communication system, and effectively ensure the security and stability of emergency communication network.
4. Establishing a converged communication system
The so-called converged communication system actually integrates the video conferencing system, voice dispatch system, and audio and video control system in the process of firefighting work, and truly guarantees the overall quality of communication under various network environments. When encountering major disasters and accidents, most communication networks and systems are in a stagnant state. Therefore, in order to effectively improve this situation and meet the communication requirements of fire rescue emergency situations, it is necessary to build a converged communication system so that the system can meet the disaster control and on-site response problems under complex conditions, issue rescue instructions in the first time, and improve the rescue effect. The construction of a converged communication system must be supported by technologies such as wireless networks and satellites. According to the differences in the development of relevant aspects in various regions, it is often necessary to pay attention to avoiding interference factors in the process of building a converged communication system, effectively improve the actual command role of the fire department in the construction of the system, and truly meet the basic requirements of communication under special conditions.
5. Build a public communication network
The so-called public communication network mainly includes conventional networks such as mobile phones, landlines, and the Internet. In the process of building emergency communication guarantee systems at major disaster sites such as fire rescue, it is necessary to continuously expand the functional scope of the public communication network to effectively meet its service requirements in video and voice modes. By relying on the comprehensive coverage of public network signals, it can truly help rescue forces rush to the disaster site from multiple parties at the first time, and can transmit data in a timely manner through public network signals. At present, the application of 4G and 5G technologies can indeed meet the basic requirements of real-time transmission of data information and video materials at the rescue site, and also provide necessary support and guarantee for relevant command departments to carry out remote decision-making.
VI. Conclusion
As a typical modern communication mode, digital microwave communication itself has significant technical advantages. From its characteristics, this communication mode is more secure and has better anti-interference ability. Therefore, in some extreme disaster situations, facing special terrain environments and natural conditions, it can ensure relatively good communication quality and effectively avoid the negative impact of terrain on rescue work. Therefore, from the perspective of the stability of information transmission and its actual role in disaster relief, the advantages of digital microwave communication are irreplaceable by other traditional communication methods.
In view of this, in the future fire emergency communication support work, we should make full use of digital microwave communication technology, establish a more complete emergency communication support system, effectively improve its actual effect in the emergency communication support process, and lay the foundation and guarantee for the rescue team to smoothly carry out emergency support and rescue work. In short, in the future fire rescue emergency support work, we should be good at using digital microwave communication technology, the technical advantages it plays will not be ignored, and it will also play an irreplaceable role in the daily work of our country’s fire rescue team.
