Fire has always been an inevitable natural disaster in our lives, and it is difficult to escape in most cases, especially the increase in high-rise and super-high-rise buildings and the rapid expansion of the mass gathering places such as shopping malls and supermarkets. . With the development and maturity of smart building technology, more and more new buildings have adopted smart fire protection systems. So what is a smart fire protection system? In this article, I will introduce what is a smart fire protection system, the main functions of the smart fire protection system, and the development prospects of the smart fire protection system. Let's take a look together.
What is a smart fire protection system
The intelligent fire protection system has the function of automatic alarm at the initial stage of the fire, and the alarm of the fire center is equipped with a telephone directly leading to the fire department, an automatic fire control cabinet, and a fire alarm broadcasting system. In the event of a fire, the intelligent fire protection system can immediately send out an alarm signal on the fire alarm in the area, and at the same time, send out an alarm signal on the alarm equipment of the fire center, and display the location or area code of the fire. Broadcast, organize personnel to evacuate safely, start the fire elevator; alarm linkage signal drives the automatic fire control cabinet, close the fire door to close the fire area, and automatically spray water or fire extinguishing agent to extinguish the fire in the fire area; start the fire pump and automatic smoke exhaust device.
The importance of smart fire protection in buildings
Because there is no fire alarm system in the commercial house, villa, or private house we live in. It is difficult to find a fire in time after the fire, and the chances of extinguishing the fire or escaping the scene are even smaller. According to statistics from the relevant departments on the place where the fire occurred and the place where the fire died, 40% of the fires occurred in residential buildings, and 70% of the fires died in housing. There are regulations in developed countries that fire alarm systems need to be installed wherever people enter and leave. Therefore, the importance of automatic fire alarms and intelligent fire protection systems in buildings is self-evident.
Main functions of smart fire protection system
1.Alarm function
The alarm terminal uses sensing technology, and wireless communication is used between the alarm terminal and the alarm receiver. Therefore, when a fire occurs, the alarm signal will be quickly transmitted to the alarm receiver by simply pressing the manual button, and the sound and light alarm device of the receiver will be activated, and the signal will be transmitted to the 119 command center (that is, the fire brigade, The sub-center is a fire squadron). If no one presses the button at the fire scene, various intelligent sensors can automatically transmit the alarm signal to the alarm receiver, and finally the alarm signal to the 119 command center, so that the fire command center can monitor and send the fire alarm in real time. Automatic alarm.
2. Information recording and playback function
The fire alarm center formulated fire fighting plans for each user in accordance with fire protection regulations (contents: user name, address, verification phone, contact information of supervisors, driving directions, normal distribution of personnel, water sources, etc.) and stored in the central database. When the user calls the police, the computer of the center will automatically display the fire extinguishing plan information of the relevant user (which can be printed out at any time), so that the police officers can quickly and accurately check the police and deal with the police. Can automatically and accurately record the alarm time, place, nuclear police process, police procedures and police results, record the commander's voice and scene conditions, provide driving directions, replay the driving trajectory and the entire process of alarming and fire fighting, and there will be no errors. Report, miss report. Due to the special processing of the alarm service network technology, the system can also have accurate and detailed records of the computer working conditions of the alarm client and the receiving end, the fire review situation of the staff after receiving the alarm, and the results of the handling of the alarm, so that the responsibilities are clearly defined. , There is a case to be investigated.
It can also display the administrative street map of the entire defense zone. If a fire occurs, there will be a bright spot flashing at the corresponding location on the map. The area map can be displayed step by step as required until the floor plan of the fire alarm unit or the floor map of the fire alarm is displayed. Relevant information in databases such as roads, water systems, bridges, gas pipelines, water pipelines, and power lines can be displayed separately, and information such as police force distribution, gas pipelines, water pipelines, and power lines can also be displayed at the same time. Some parts, such as fire fighting plan, can be enlarged.
3.Command function
Once there is a fire alarm, the accurate location (longitude and latitude) of the alarm point and the driving route to the fire point will be automatically displayed on the electronic map of the alarm center immediately. At the same time, it can also send early warning information, police preplans, and exit orders to the relevant fire squadrons and fire trucks to prepare them in advance for rapid police handling. Because the receiving end uses a high-quality full-automatic design, it has automatic query, detection, and judgment functions for false positives and malicious alarms, and automatic shutdown and denial of service functions for illegal users. When the user calls the police, the computer of the alarm center will automatically display the fire fighting plan information of the relevant user, including: user name, address, verification phone, contact information with the supervisor, driving directions, internal details, normal distribution of personnel, Location of escape routes, characteristics of combustible fuels, hydrants, water conditions, police deployment and fire extinguishing force deployment. These data are prepared for users by the alarm center in accordance with fire protection regulations in advance and stored in the database of the center. The police program can also be prepared manually or automatically and printed out for use by relevant personnel.
When a fire alarm occurs, the alarm center can call up comprehensive and informative relevant information and materials that reflect the fire protection system in its jurisdiction at any time. Such as: the personnel situation of each fire squadron, fire equipment equipment, vehicle conditions, and vehicle schedule, driver schedule, fireman's watch and other related information. The above information can be updated and expanded at any time as circumstances change. The alarm center can analyze and judge according to the fire type, fire level, meteorological conditions, geographical environment, fire water sources, fire fighting strength, basic conditions of the fire alarm unit, and other related factors, and automatically or manually formulate a police plan, and send the fire squadron, The fire truck issued an order. Once there is a fire alarm, the receiving center and the fire-fighting mobile terminal (fire truck) can keep receiving and displaying the information transmitted in real time, and the receiving center, users and police officers can keep talking with each other.
4, fire mobile terminal (fire truck) function
The fire truck is equipped with GPS satellite positioning autonomous navigator. When an alarm is received, the GPS satellite positioning autonomous navigator equipped on the vehicle can display the location, route, user name, etc. of the alarm, call out the fire extinguishing plan information of the alarm user, connect the GSM call function and call the monitoring center, Reach the trinity of detachment, squadron and fire truck to form a network. At the same time, it can provide fire trucks with driving directions to the fire alarm point.
