Description

Technical Field

[0001] This invention relates to the field of fire alarm technology, and more specifically, to a fire detection, alarm, and fire-fighting linkage control method and system. Background Technology

[0002] With increasing attention to fire safety, more and more construction sites are installing fire detectors and fire protection systems. When a fire occurs, the fire detectors will sound an alarm, and the fire department will only dispatch personnel after receiving the fire alarm.

[0003] Fire detectors in buildings are a core component of the fire safety system. They are the triggering source for fire-fighting linkage systems (such as automatic sprinklers, ventilation and smoke extraction, and broadcasting systems). Their reliability directly affects the effectiveness of the entire fire protection system, which is related to life safety and property protection, as well as social responsibility and compliance.

[0004] However, in the current fire management process, it is impossible to conduct safety supervision and analysis on fire detectors, which can easily lead to untimely and unreliable early warnings. It is also impossible to combine the different environmental characteristics of building sites to conduct early warning diagnosis of fire risks, which increases the difficulty of subsequent fire rescue.

[0005] Therefore, in response to the problems existing in the fire monitoring and alarm technology, a fire detection alarm fire linkage control method and system are proposed. Summary of the Invention

[0006] The purpose of this invention is to solve existing practical problems and provide a fire detection, alarm, and fire-fighting linkage control method and system compared with existing technologies.

[0007] The objective of this invention can be achieved through the following technical solution: a fire detection, alarm, and fire-fighting linkage control method system, comprising a fire management platform, a detection equipment management module, a fire detection module, an early warning and control module, an alarm response module, and a fire control module;

[0008] The fire management platform is used to divide the building site into multiple detection zones and acquire the detection facilities within the detection zones, including all fire detectors;

[0009] The detection equipment management module is used to collect facility information of all fire detectors in the detection area, determine whether the detection facilities meet the fire early warning requirements based on the facility information, and generate a qualified fire early warning signal or a fire early warning control signal, which are sent to the fire detection module and the early warning control module respectively.

[0010] The early warning and control module divides the detection area corresponding to the fire early warning and control signal into a control area, and adjusts the position and specifications of the detection facilities within the control area;

[0011] The fire detection module responds to qualified fire early warning signals, collects fire characteristic data and regional characteristic data of the detection area, performs fire risk correlation prediction analysis on the detection area, and sends the obtained risk level results to the fire management platform.

[0012] The fire management platform determines whether to activate fire control commands based on the risk level results. Fire control commands include low-risk alarm commands and high-risk alarm commands. The fire control commands are sent to the fire control module. The fire control module responds to the low-risk alarm commands and high-risk alarm commands and takes low-risk and high-risk execution measures respectively.

[0013] Furthermore, the process of determining whether fire detectors within the detection area meet the requirements for fire early warning includes:

[0014] The detection equipment management module obtains the facility information of each fire detector. The facility information includes coverage data and performance index data. The coverage data includes the protection radius and applicable height of the fire detector. The performance index data includes the allowable differential pressure, monitoring current and response time of the fire detector. Each data item in the facility information is compared and analyzed with the preset standard data threshold.

[0015] If every data item in the facility information of a fire detector is within the preset standard data threshold range, the fire detector is marked as a qualified detector; otherwise, it is marked as an unqualified detector. When all fire detectors are marked as qualified detectors, it is determined that the detection facilities in the detection area meet the fire early warning requirements, and a qualified fire early warning signal is generated. Otherwise, it is determined that the detection facilities in the detection area do not meet the fire early warning requirements, and a fire early warning control signal is generated.

[0016] Furthermore, the process of adjusting the location and specifications of the detection facilities within the control area includes: the early warning control module obtains the identification number and location of the unqualified detectors within the control area, and retrieves coverage data and performance index data. When any data item in the coverage data is not within the preset standard threshold range, a coverage abnormality signal is generated. When any data item in the performance index data is not within the preset standard threshold range, a performance index abnormality signal is generated.

[0017] For unqualified detectors that only generate coverage abnormality signals, relocate and install them; for unqualified detectors that only generate performance abnormality signals, replace them with new ones; and for unqualified detectors that generate both coverage abnormality signals and performance abnormality signals, replace them with new ones and relocate and install them.

[0018] Furthermore, fire characteristic data includes smoke concentration, temperature value, combustion product concentration, flame heat release rate, and heat flux in the detection area; regional characteristic data includes environmental indicators, combustible material indicators, electrical system indicators, and fire extinguishing indicators.

[0019] Furthermore, the process of fire detection module performing fire risk correlation prediction analysis includes:

[0020] All regional feature data items are compared one by one with the corresponding regional feature standard range. If all regional feature data items do not exceed the preset standard range, a regional feature risk-free signal is generated; otherwise, a regional feature risk signal is generated.

[0021] All fire characteristic data items are compared one by one with the corresponding fire characteristic standard range. When all fire characteristic data items do not exceed the preset standard range, a fire characteristic no-risk signal is generated. When any fire characteristic data item exceeds the preset standard range, a fire characteristic primary risk signal is generated. A fire characteristic risk curve is plotted with the acquisition time as the x-axis and the real-time acquired fire characteristic data items as the measured values ​​as the y-axis. When any two fire characteristic data items in all fire characteristic risk curves show an increasing trend, a fire characteristic high-risk signal is generated.

[0022] Furthermore, based on a comprehensive assessment of multiple risk signals, the fire detection module generates signals indicating no fire hazard, a level-three risk warning, a level-two risk warning, or a level-one risk warning.

[0023] Furthermore, the process for determining whether to activate fire control commands includes: when the fire management platform receives a signal indicating no fire hazard, it does not activate fire control commands; when it receives a level 3 risk warning signal, it activates a low-risk alarm command; and when it receives a level 2 or level 1 risk warning signal, it activates a high-risk alarm command.

[0024] This invention also proposes a fire detection, alarm, and fire-fighting linkage control method, comprising the following steps:

[0025] Step 1: Determine whether the detection facilities in the detection area meet the fire early warning requirements. If not, divide the detection area into a control area and adjust the location and specifications of the detection facilities in the control area. If the requirements are met, proceed to Step 2.

[0026] Step 2: Collect fire characteristic data and regional characteristic data of the detection area, conduct fire risk correlation prediction analysis on the detection area, and obtain the risk level results;

[0027] Step 3: Determine whether to activate the fire control command based on the risk level results. If the fire control command is activated, take appropriate action.

[0028] Compared with the prior art, the advantages of this invention are:

[0029] 1. This invention achieves fire response linkage control through a closed-loop "detection-decision-execution" path. For the "detection-decision" stage, it uses standardized multi-source data acquisition to determine whether detection facilities meet fire early warning requirements, improving the reliability and timeliness of trigger source information acquisition in the fire linkage system and reducing the risk of false alarms and missed alarms. By acquiring standardized multi-source fire characteristic data and regional characteristic data, and combining internal and external quantitative evaluation indicators with a logical diagnostic model, it predicts and analyzes fire risk, systematically improving the reliability of fire early warning diagnosis and thus reducing the difficulty of subsequent fire rescue.

[0030] 2. Based on the above, analyze the facility information of all fire detectors in the detection area to determine whether the detection facilities meet the fire early warning requirements. If not, divide the detection area into a control area and adjust the location and specifications of the detection facilities in the control area to ensure that the fire control performance in the fire monitoring area can meet the actual area requirements. The detection accuracy determines the reliability and timeliness of the early warning response.

[0031] 3. Collaborative analysis of regional environmental impacts to predict fire risks; comprehensive risk classification and logical diagnosis to determine the reliability of fire protection implementation; closed-loop control to dynamically match fire risk levels with implementation measures.

[0033] Figure 2 This is a block diagram of the method logic of the present invention. Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Example 1: This invention discloses a fire detection, alarm, and fire-fighting linkage control system. Please refer to [link / reference]. Figure 1 , Figure 2 It includes a fire management platform, a detection equipment management module, a fire detection module, an early warning and control module, an alarm response module, and a fire control module;

[0036] The fire management platform is used to divide the building site into multiple detection zones, acquire the detection facilities in the detection zones, including all different types of fire detectors, and label them one by one.

[0037] The detection equipment management module is used to collect facility information of all fire detectors in the detection area, and determine whether the detection facilities meet the fire early warning requirements based on the facility information. The specific determination process includes:

[0038] Obtain facility information for each fire detector, including coverage data and performance index data. Coverage data includes the protection radius and applicable height of the fire detector, while performance index data includes the allowable differential pressure, monitoring current, and response time of the fire detector. Compare and analyze each data item in the facility information with preset standard data thresholds.

[0039] If every data item in the facility information of a fire detector is within the preset standard data threshold range, the fire detector is marked as a qualified detector; otherwise, it is marked as an unqualified detector. When all fire detectors are marked as qualified detectors, it is determined that the detection facilities in the detection area meet the fire early warning requirements, and a qualified fire early warning signal is generated. Otherwise, it is determined that the detection facilities in the detection area do not meet the fire early warning requirements, and a fire early warning control signal is generated.

[0040] The overall early warning performance of fire detectors is judged from two aspects: coverage data and performance index data. If the coverage and layout requirements and the performance requirements of the detectors are met, they are considered reasonable. Otherwise, the quantity, location or specifications need to be adjusted. High-performance and correctly arranged fire detectors can ensure the rapid transmission of fire signals, shorten the response time, improve the reliability of the fire linkage system's trigger source information collection, and reduce the risk of false alarms and missed alarms.

[0041] The generated fire early warning qualified signal and fire early warning control signal are sent to the fire detection module and the early warning control module, respectively.

[0042] The early warning and control module responds to the fire early warning and control signal, divides the detection area corresponding to the fire early warning and control signal into a control area, and adjusts the location and specifications of the detection facilities within the control area. The specific process includes:

[0043] Obtain the identification number and location of the unqualified detectors within the control area, and retrieve coverage data and performance index data. When any data item in the coverage data is not within the preset standard threshold range, a coverage abnormality signal is generated. When any data item in the performance index data is not within the preset standard threshold range, a performance index abnormality signal is generated.

[0044] For unqualified detectors that only generate coverage abnormality signals, relocation and installation should be carried out. For unqualified detectors that only generate performance abnormality signals, specification replacement should be carried out. For unqualified detectors that generate both coverage abnormality signals and performance abnormality signals, specification replacement and relocation and installation should be carried out simultaneously. The location and specification of unqualified detectors in the control area should be adjusted to ensure that the fire control performance in the fire monitoring area can meet the actual needs of the area, thereby improving detection accuracy. Detection accuracy determines the reliability and timeliness of early warning response and reduces the risk of false alarms and missed alarms.

[0045] The fire detection module responds to qualified fire early warning signals and collects fire characteristic data and regional characteristic data of the detection area;

[0046] Among them, fire characteristic data include smoke concentration, temperature value, combustion product concentration, flame heat release rate, and heat flux in the detection area;

[0047] Regional characteristic data includes environmental indicators, combustible material indicators, electrical system indicators, and fire extinguishing indicators. Environmental indicators include ambient temperature and air circulation speed. Combustible material indicators include fire load value and combustible material critical value, focusing on the properties and distribution of combustible materials themselves. When combustible materials are concentrated in a large continuous space, the fire load is high and the stacking density is too large. For example, if the goods are stacked above the height of the fire lane, it will hinder evacuation and fire extinguishing. The combustible material critical value represents the minimum conditions for combustible materials to spontaneously combust or be ignited, such as temperature, oxygen concentration, and heat flux value. When the combustible material critical value is low, it will aggravate the scale of the fire and the possibility of its spread. Electrical system indicators include the number of electrical equipment and the frequency of historical electrical equipment failures. Old lines, overloaded electricity, and short circuit faults are the main causes of electrical fires. Fire extinguishing indicators include the number of fire hydrants and the coverage radius of fire hydrants, reflecting the coverage rate of fire extinguishing equipment.

[0048] The fire detection module combines fire characteristic data and regional characteristic data to perform fire risk correlation prediction analysis on the detection area and sends the obtained risk level results to the fire management platform.

[0049] The process of conducting fire risk correlation prediction analysis includes: comparing all regional characteristic data items with the corresponding regional characteristic standard range one by one; when all regional characteristic data items do not exceed the preset standard range, a regional characteristic risk-free signal is generated; otherwise, a regional characteristic risk signal is generated.

[0050] All fire characteristic data items are compared one by one with the corresponding fire characteristic standard range. When all fire characteristic data items do not exceed the preset standard range, a fire characteristic no-risk signal is generated. When any fire characteristic data item exceeds the preset standard range, a fire characteristic primary risk signal is generated. A fire characteristic risk curve is plotted with the acquisition time as the x-axis and the real-time acquired fire characteristic data items as the measured values ​​as the y-axis. When any two fire characteristic data items in all fire characteristic risk curves show an increasing trend, a fire characteristic super-risk signal is generated.

[0051] Based on the comprehensive assessment of the above multiple risk signals, signals of no fire hazard, level 3 risk warning, level 2 risk warning, or level 1 risk warning are generated respectively. These signals are sent to the fire management platform as risk level results. By collecting standardized multi-source fire characteristic data and regional characteristic data, and combining internal and external quantitative assessment indicators with a logical diagnostic model, fire risk can be predicted and analyzed, which can systematically improve the reliability of fire early warning diagnosis.

[0052] The comprehensive assessment process for multiple risk signals is as follows: when both regional characteristic risk-free signals and fire characteristic risk-free signals are generated simultaneously, a no-fire-hazard signal is generated; when both regional characteristic risk-free signals and fire characteristic primary risk signals are generated simultaneously, or both regional characteristic risk signals and fire characteristic risk-free signals are generated simultaneously, a level-three risk warning signal is generated; when both regional characteristic risk signals and fire characteristic primary risk signals are generated simultaneously, or both regional characteristic risk-free signals and fire characteristic high-risk signals are generated simultaneously, a level-two risk warning signal is generated; and when both regional characteristic risk signals and fire characteristic high-risk signals are generated simultaneously, a level-one risk warning signal is generated.

[0053] Example 2: Please refer to Figures 1-2 The fire management platform determines whether to activate fire control commands based on the risk level results. Fire control commands include low-risk alarm commands and high-risk alarm commands.

[0054] When the fire management platform receives a signal indicating no fire hazard, it marks the detection area as a safe area and does not initiate fire control commands. When it receives a level 3 risk warning signal, it marks the detection area as a low-risk fire area and initiates a low-risk alarm command. When it receives a level 2 risk warning signal or a level 1 risk warning signal, it marks the detection area as a high-risk fire area respectively, initiates a high-risk alarm command, and sends the low-risk alarm command and high-risk alarm command to the fire control module.

[0055] The fire control module responds to low-risk and high-risk alarm commands and takes low-risk and high-risk action measures respectively. The closed-loop control can dynamically match the fire risk level with the action measures.

[0056] The specific process is as follows: When the fire control module responds to the low-risk alarm command, it takes low-risk action measures, automatically activates the audible and visual alarms and closes the fire doors for the low-risk fire area, and sends the level three risk warning signal to the management personnel, who then organize the orderly evacuation of personnel.

[0057] When the fire control module responds to a high-risk alarm command, it takes high-risk action measures. For high-risk fire areas, it automatically activates audible and visual alarms, closes fire doors, automatically opens fire hydrants or fire extinguishing systems, and sends a level-two or level-one risk warning signal to management personnel and firefighters. Management personnel organize the orderly evacuation of personnel, and firefighters organize fire extinguishing activities.

[0058] Example 3, in conjunction with Examples 1 and 2, shows that the present invention also proposes a fire detection, alarm, and fire-fighting linkage control method, comprising the following steps:

[0059] Step 1: Collect facility information of all fire detectors in the detection area, determine whether the detection facilities in the detection area meet the fire early warning requirements. If not, divide the detection area into a control area and adjust the location and specifications of the detection facilities in the control area. If the requirements are met, proceed to Step 2.

[0060] Step 2: Collect fire characteristic data and regional characteristic data of the detection area, conduct fire risk correlation prediction analysis on the detection area, and obtain the risk level results;

[0061] Step 3: Determine whether to activate the fire control command based on the risk level results. The fire control command includes low-risk alarm command and high-risk alarm command. When a low-risk alarm command is activated, low-risk execution measures are taken. When a high-risk alarm command is activated, high-risk execution measures are taken.

[0062] It should be added that the various thresholds mentioned in the article, such as thresholds, preset values, and preset ranges, are set for result comparison and analysis to determine good or bad. The magnitude of these thresholds is determined by a combination of large-scale model analysis of sample data and human experience, and can also be appropriately adjusted based on seasonal or common-sense influencing factors.

[0063] In summary, the solution is constructed from three parts: detection, control, and execution. It achieves fire response linkage control through a closed-loop "detection-decision-execution" path. Particularly for the "detection-decision" stage, standardized multi-source data collection determines whether detection facilities meet fire early warning requirements, improving the reliability of trigger source information acquisition in the fire linkage system and reducing the risk of false alarms and missed alarms. By collecting standardized multi-source fire characteristic data and regional characteristic data, and combining internal and external quantitative evaluation indicators with intelligent diagnostic models, fire risk prediction and analysis can be performed, systematically improving the reliability of fire early warning diagnosis and thus reducing the difficulty of subsequent fire rescue.

[0064] Among them, detection accuracy determines the reliability and timeliness of early warning response, risk logic diagnosis determines the reliability of fire protection execution, and the response of execution equipment to execution signals determines the fire extinguishing effect.

[0065] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto; any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
