Research on Computer Realization of Building Fire Safety Assessment

Fire is a kind of sporadic local disaster phenomenon. The building fire in the fire has brought very serious losses to people’s life and property. With the increase of the urban population, the increase of the number of building floors, the increase of the density of urban settlements, and the widespread use of electrical, natural gas and chemical substances in buildings, the possibility of fire and the losses caused by the building are also increasing, especially some houses of longer construction age, lack of fire fighting facilities and serious consequences in the event of fire. In recent years, computer technology has been applied to a certain extent in all fields of our country. The effective use of computer technology has further improved the technical level of building fire safety management, and then realized the automatic management of building fire prevention to some extent. In this case, the fire prevention management of buildings has higher sensitivity and safety, which brings more protection to the safety of people’s lives and property. To understand the application of computer technology in building fire safety management, and then to better apply computer technology, can promote the development of building fire safety management.

The practical application of fire prevention system in computer building
In the aspect of fire prevention judgment, the computer building fire prevention system can assist the operator to judge the fire prevention information and situation, and then save more fire fighting time and provide convenience for the fire fighting and rescue work. On the one hand, when dealing with fire alarm, the system can judge the degree and type of fire on the monitoring screen. After judging the degree and type of fire, the system will judge whether the area belongs to the key defense area, and then arrange the alarm library. On the other hand, the system can collect the relevant information and fire plan of the fire area, and send the information to the terminal of the squadron, and show the receiving situation of the information. Moreover, if the fire area does not belong to the key defense area, the system will direct the operator to query, compare and analyze the data in the system database with the assistance of the expert system. In this case, the operator can judge the fire prevention ability of the local fire prevention team according to the telephone number or address, and judge the fire size and the cause of the fire at the same time. After the judgment is completed, the system can execute the dispatch order and display the specific fire fighting plan and information, thus helping the operator to complete the basic fire prevention judgment work [2].When dealing with fire alarm, the computer aided expert decision system makes artificial judgment according to the degree and type of fire displayed on the screen. If it does not belong to the key defense area, the system automatically enters the expert decision system. Through the expert system prompt, the command operator uses the data recorded in the expert decision system database to compare, query and analyze. According to the telephone number or area address in the area information to judge the fire prevention ability of the local fire prevention team, check the fire size and the cause of the fire. The system can automatically generate dispatching orders, which can show the natural environment, terrain, water quantity, fire material and so on. The key security units should make a good protection plan, such as fire fighting measures, maps, the number of personnel dispatched, the number of fire fighting equipment and how to use, fire fighting defense layout plan and so on. Computer-aided expert decision-making system is an important tool for operators to make auxiliary judgment, which reduces the time of artificial fire prevention judgment, and briefly shortens the time of. It is a necessary link of the whole system.Therefore, the computer fire safety system is very effective. As shown in Figure 2, it shows the application of computer fire prevention system. situation on the spot, and finally achieve the purpose of effective command and operation. The fire alarm handling and dispatching system is a control system that connects the alarm telephone through optical fiber to the local fire department. The command center stores the telephone number and geographic information in the alarm information. The command center can monitor, connect and intercept the telephone information of the alarm. Especially for the mobile phone alarm, the system can automatically connect the telephone to the local fire brigade, where the command department to handle the nearest, convenient and fast [4].

In the application of computer technology to carry out security research
In the application of computer technology to the fire safety management of buildings, we must do a good job in the maintenance and management of technical equipment, and improve the system database management, so that the fire prevention system of computer buildings can play its greatest role. And then for the people's life and property safety to provide more protection. Because the building fire prevention involves a lot of knowledge, the content is extensive, the building fire prevention knowledge is arranged and divided into the following two categories: First, deterministic knowledge, such as the implementation of fire prevention norms, only compliance with norms and non-conformity with the second class, there is no intermediate answer, such as fire prevention zoning, deterministic knowledge, part of the target knowledge, this kind of knowledge can be directly used to solve problems, part of meta-knowledge, This kind of knowledge is the further explanation, explanation or control strategy to guide the target knowledge.
Second, non-deterministic knowledge, this kind of knowledge can not be simply judged by right and wrong, is or not, such as fire safety knowledge learning and training, in the design of the system, the use of fuzzy methods to give such knowledge a certain degree of credibility, and through fuzzy operations, draw a conclusion with credibility, the system of building fire-proof total score: Because of the importance of building fire prevention design and construction, if one of the two points is less than 60 points, the system determines that the fire safety of the building is poor [5].
In order to realize many functions of computer building fire prevention system, the system is composed of many kinds of precise equipment and instruments. Therefore, in the daily management work, we should strengthen the maintenance and management of technical equipment, so that the equipment can play a normal role, and then prolong the service life of the equipment. On the one hand, it is necessary to check the power supply of the equipment regularly. Once the equipment is found to be insufficient, it is necessary to charge or replace the battery in time, so as to avoid the phenomenon of equipment failure. On the other hand, the wireless optical fiber equipment should be checked regularly to avoid human damage. In the installation of optical fiber equipment, the location of the installation should be reasonably selected to prevent the equipment from being damaged. In addition, the management should do a good job in the maintenance of the computer equipment in the command center, and then ensure the networking speed and daily normal use of the equipment. At the same time, managers should do a good job in daily life system database maintenance and management. On the one hand, managers should regularly check the database of each subsystem of the system, and collate and check the system data. Once the data is found to be abnormal, contact professionals to repair and maintain the system data. On the other hand, managers should set the administrative authority of the system to prevent the data in the database from being deleted or modified incorrectly [6].

Conclusion
In a word, building fire prevention management is an important work of fire protection construction in China, which is of great significance to ensure the safety of people and country's life and property. The intelligent management of computer building fire prevention system has played a good auxiliary role in the continuous development of this cause. We should pay more attention to the application of computer technology in the field of fire protection. Only by doing a good job in building fire safety management can we provide the most basic guarantee for the safety of people's lives and property. The application of computer technology in fire prevention judgment, daily fire safety management and fire automation management makes building fire safety management more convenient and effective, so people should strengthen the application of computer technology. For the staff of building fire safety management, in order to better apply computer technology, it is necessary to do a good job in the maintenance and management of technical equipment and system database.
