I. Introduction. With the acceleration of urbanization, the issue of fire safety has attracted more and more attention. As a new type of fire protection mode, smart fire protection can improve the intelligent level of fire prevention and control and reduce the possibility of fire. Among them, the multi-device linkage fire alarm system, as an important part of smart fire protection, is of great significance for timely detection of fires and rapid response measures. This article will detail the application of multi-device linkage fire alarm system in smart fire protection.
Second, the basic principle of multi-device linkage fire alarm system.
Multi-device linkage fire alarm system is a comprehensive fire alarm system that integrates a variety of sensing equipment, communication technology and data processing technology. The system realizes real-time monitoring of various parameters in the event of a fire by deploying various types of detectors such as smoke detectors, temperature sensors, and infrared detectors in the building. Once an abnormal situation is found, the system will immediately start the alarm program, and through the linkage control mechanism, quickly start the corresponding fire extinguishing equipment, and send alarm information to the fire department at the same time.
3. Advantages of multi-device linkage fire alarm system.
1.Early warning: Through the integrated application of a variety of sensors, real-time monitoring and data analysis of various parameters in the event of a fire can be realized, and the timeliness and accuracy of fire early warning can be improved.
2.Rapid response: Once a fire is found, the system can quickly start the alarm program, and through the linkage control mechanism, start the corresponding fire extinguishing equipment to minimize the loss caused by the fire.
3.Intelligent management: The system has strong data processing capabilities, which can classify, store and analyze fire alarm information, and provide scientific and accurate decision-making basis for the fire department.
4.Remote monitoring: With the help of the Internet of Things and communication technology, the remote monitoring and management of the fire alarm system can be realized, and the efficiency and quality of fire protection work can be improved.
5.Strong compatibility: The system has good compatibility and can be integrated with various fire-fighting equipment and systems to meet the fire-fighting needs of different places and scales.
Fourth, the application scenario of multi-device linkage fire alarm system.
1.Residential area: The deployment of multi-device linkage fire alarm system in residential community can realize real-time monitoring and early warning of fire and ensure the safety of residents' lives and property.
2.Commercial buildings: The internal structure of commercial buildings is complex and densely populated, and the use of multi-device linkage fire alarm system can effectively improve fire prevention and control capabilities and reduce the risk of fire.
3.Industrial parks: There are fire hazards in the production equipment, raw materials and products in the industrial park, and the rapid response and disposal of the fire can be realized through the installation of a multi-equipment linkage fire alarm system, and the impact of the fire on industrial production can be reduced.
4.Public places: The installation of multi-device linkage fire alarm systems in public places such as airports, stations, and shopping malls can improve the fire safety level of places and ensure the safety of the public.
5.Ancient buildings: Ancient buildings are mostly wooden structures, which are very easy to cause fires and serious losses. By deploying a multi-device linkage fire alarm system in ancient buildings, real-time monitoring and early warning of fire can be realized, and fire can be detected and dealt with in time.
5. Introduction of Ankerui smart fire protection platform.
5.1. Platform structure.
5.2. Introduction to the main functions of the platform.
5.2.1 Home.
After the user logs in successfully, he enters the home page, as shown in the figure. The main contents of the display are: project overview, equipment status, equipment classification, equipment alarm information, alarm classification, alarm statistics, equipment ledger information, etc. Among them, the map can be optionally configured as a BIM building model, and any sensor alarm can be displayed in the BIM model.
5.2.2. Fire protection subsystem.
The smart fire management cloud platform includes intelligent electronic systems, smoke prevention and exhaust subsystems, fire water subsystems, fire equipment power supply subsystems, fire door subsystems, fire equipment management subsystems and monitoring subsystems. The intelligent electronic system can be connected to electrical fire, lone arc, electrical fire host, arc extinguishing protector detector and wireless temperature detector. Click on the smart electronic system to enter the smart electricity monitoring page, click the menu to display the basic information of the entire project and the information of all detectors under the project, and click the last node to display the monitoring page of specific detectors.
The fire water subsystem can be connected to the fire hydrant, fire water pressure, water level sensor, etc., for real-time monitoring of the pressure, liquid level, whether there is water leakage, and opening the cover and other events of the fire water pipe network.
The smoke prevention and exhaust subsystem realizes the data collection of smoke, harmful gases, and gas fire extinguishing information through the highly sensitive wireless smoke alarm device, real-time detection of smoke in seconds, and finds that the monitoring number exceeds the risk threshold.
The power supply subsystem of fire-fighting equipment monitors the power supply working status of each component of the fire-fighting system (such as fire alarm host, floor display, water pump, sprinkler pump, elevator, etc.) in real time to ensure the normal power supply of fire-fighting equipment, and gives alarm prompts for overvoltage, undervoltage, overcurrent, short circuit, open circuit and other faults generated by the power supply of each component. It can record the voltage and current operating parameters for a long time, automatically analyze the operating status of the fire power supply for a period of time, and warn the hidden dangers that may produce problems.
The fire door subsystem monitors the opening and closing of fire doors, safety exits, life passages, fire doors and stacked objects in fire passages in real time through the association with access control alarm and identification, so as to realize the opening and closing control and other functions in emergency situations. Ensure that the fire door is normally closed and not locked, and ensure that the fire rescue is the smooth passage of fire life, etc., to ensure a safe living and working environment.
The emergency lighting and evacuation indication subsystem can realize real-time monitoring and control of each emergency lamp, and when a fire occurs, it can accurately give a safe evacuation path indication, intelligently turn on the direction of the fire emergency indicator and emergency lighting, and help the people in the building choose an escape and evacuation route and guide the safe escape direction.
* After receiving the alarm information of each subsystem at the sensing end, the data department of the monitoring subsystem can call up the surveillance camera image associated with the alarm position to view the alarm scene and assist in confirming the fire situation. Realize the organic combination of fire alarm subsystem, fire water subsystem, electrical fire subsystem, smoke prevention and exhaust subsystem, fire equipment power supply subsystem, fire door subsystem and monitoring subsystem, and realize the linkage of alarm points and monitoring points.
The fire-fighting equipment management subsystem can incorporate all fire-fighting equipment and assets of each building and project node into the management, and highlight the addresses of some fire hydrants, fire extinguishers, sprinklers and fire brigades, etc., and the daily inspection and maintenance need to be included in the plan.
