Future Development Trends of Fire Communication Technology (1)

Fire communication is an important part of firefighting work. It is the nervous system of firefighting dispatch, organization and command. With the rapid development of communication technologies and computer technologies, some cities in China have implemented fire-fighting communication networks composed of advanced technology and equipment such as computers, cable, wireless communication, and image transmission, thereby improving the scientific and automatic level of fire-fighting equipment systems. This has greatly increased the ability of the force to respond to fires, respond to severe fires, and adapt to the multi-corporate command capability of cross-regional operations. As a modern technology and equipment for firefighting, the fire communication command system plays an important role in urban firefighting work.

This article will discuss the development trend of the fire communication command system.

First, the status of fire communications command Fire communications command center, fire basic squadron, fire command vehicle, city key security units and related departments and other links together constitute a fire communications command system, it is the fire police acceptance, strength scheduling and auxiliary fire fighting decision-making functions The organic whole of communication networks and equipment. Fire communication is an important part of firefighting work, and it plays an important role in protecting the fire rescue mission by transmitting information. In the initial period of reform and opening up, especially after the fire communication command system design specifications came out, the technical composition, system equipment configuration and functional requirements, and software design requirements of firefighting communications provided more standardized guiding principles and technical basis, and led to the construction of a communications command system. Entered the normal development track. At the same time, a small number of cities have initially established a municipal fire communication command system, which effectively increases the annual handling capacity of fire alarms and fires. In more developed countries abroad, especially in the United States, Japan, and other countries, due to the relatively good economic foundation and the rapid development of computers and communication technologies, issues such as fire-fighting communications and fire-fighting information computer management have been well resolved in computer-aided decision-making. A lot of work has been done on simulation training and is still being further improved. In China, the fire communication command system started late, but currently major cities are working hard to build a modern fire communication command system with relatively complete functions, advanced efficiency, and reasonable application. It mainly adopts advanced technologies for modern computer, communication, control and information comprehensive decision making, and integrates wired and wireless communications, computer networks, computer-aided decision-making, geographic information systems, global satellite positioning systems, image processing and display, automatic control technologies and data. Management is equal to one construction.

Through several years of construction, most cities have established a fire dispatching and command system that concentrates on receiving alarms; wireless communication equipment has been greatly improved, initially forming a wireless communication network above level two, improving the quality of wireless communications; fire alarms, scheduling, and dispatching The line configuration has greatly increased compared with before; in some places, the use of telecommunications or public security special networks improves the automation of office and automatic management, and basically achieves no-end office.

Second, the brief history of the development of fire communications The earliest forms of fire communications appeared in China, and the Tang and Song Dynasties began to use gongs, drums, and semaphores. However, due to the fact that our country’s once-failing recession at the end of the Qing dynasty was left behind by other countries, while the country still remained in the original firefighting communications, some countries in the United States and the United Kingdom began to emerge modern fire-fighting communications, such as the introduction of telephones.

China's fire communication technology was developed after the founding of New China. Compared with foreign countries, there are certain gaps in all aspects. When the new China was just established, China's fire-fighting communications were limited to telephone alarms. Wired communications were still lagging behind. There were basically no advanced tools in the fire scene, and their means were very simple. Usually shouts, lights, gestures, etc. were used.

In the 1960s, firefighting work was well developed and firefighting communication equipment was also improved. In terms of wireline communications scheduling, power-supply switches began to be used, and some fire squadrons established a simple fire alarm dispatcher to meet the needs of dispatchers. In wireless communications scheduling, short-wave radios and telegraphs have begun to be used.

In the 1970s, VHF FM radios began to appear. Shortwave AM radiotelephones, radiotelegraphs, and wireline wireless switching equipment were gradually eliminated. As the use of radiotelephones gradually increased, wireless communication networking technology began to develop. . After the Third Plenary Session of the Eleventh Central Committee, China began to implement reform and opening up, and the economy has developed rapidly. This period is also a period of rapid development of firefighting. In the fire-fighting communications sector, special fire alarm dispatchers have been launched one after another, and some power-supply switches have been eliminated. At present, fire-fighting basically uses special fire alarm dispatcher series equipment, and the wired communication network has been completed.
