Description

Technical Field

[0001] The present invention relates to the technical field of fire alarm technology, and more particularly to a fire detection alarm and fire fighting linkage control method and system. Background Art

[0002] As people pay more attention to fire safety, more and more construction sites are equipped with fire detection alarms and fire protection systems. When a fire occurs, the fire detection alarm will sound an alarm, and the fire department will only respond after receiving the fire alarm.

[0003] Fire detectors in buildings are a core component of the fire safety system and the trigger source for fire linkage systems (such as automatic sprinklers, ventilation and smoke exhaust, and broadcasting systems). Their reliability directly affects the effectiveness of the entire fire protection system, affecting not only life safety and property protection, but also social responsibility and compliance.

[0004] However, in the current fire management process, it is impossible to conduct safety supervision and analysis of fire detectors, which can easily lead to untimely and low-reliability early warnings. It is also impossible to conduct early warning and diagnosis of fire risks based on the different environmental characteristics of building sites, which increases the difficulty of subsequent fire rescue. Therefore, in view of the fire monitoring and alarm problems existing in the prior art, a fire detection alarm and fire fighting linkage control method and system are proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the existing practical problems and provide a fire detection alarm fire fighting linkage control method and system compared with the existing technology.

[0006] The object of the present invention can be achieved by the following technical solutions: A fire detection alarm fire fighting linkage control method system, comprising a fire management platform, a detection equipment management module, a fire detection module, an early warning control module, an alarm response module and a fire control module; The fire management platform is used to divide the building site into multiple detection areas and obtain the detection facilities within the detection areas, including all fire detectors; The detection equipment management module is used to collect the facility information of all fire detectors in the detection area, determine whether the detection facilities meet the fire warning requirements based on the facility information, and generate a fire warning qualification signal or a fire warning control signal, which are sent to the fire detection module and the warning control module respectively; The early warning and control module divides the detection area corresponding to the fire early warning and control signal into control areas, and adjusts the position and specifications of the detection facilities within the control areas; The fire detection module responds to the fire warning qualified signal, collects the 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; The fire management platform determines whether to initiate fire control instructions based on the risk level results. Fire control instructions include low-risk alarm instructions and high-risk execution instructions, and sends the fire control instructions to the fire controlled module. The fire controlled module responds to low-risk execution instructions and high-risk execution instructions, and takes low-risk execution measures and high-risk execution measures respectively.

[0007] Furthermore, the process of determining whether the fire detectors within the detection area meet the fire warning requirements includes: The detection equipment management module obtains the facility information of each fire detector, including coverage data and performance indicator data. The coverage data includes the fire detector's protection radius and applicable height, and the performance indicator data includes the fire detector's allowable pressure difference, monitoring current, and response time. Each data item in the facility information is compared and analyzed with the preset standard data threshold. When each data item in the facility information of the fire detector is within the preset standard data threshold range, the fire detector will be marked as a qualified detector, otherwise it will be marked as an unqualified detector. When all fire detectors are marked as qualified detectors, it is judged that the detection facilities in the detection area meet the fire warning requirements and a fire warning qualified signal is generated. Otherwise, it is judged that the detection facilities in the detection area do not meet the fire warning requirements and a fire warning control signal is generated.

[0008] Furthermore, the process of adjusting the position and specification of the detection facilities in the control area includes: the early warning control module obtains the number and position of the unqualified detector in the control area, and retrieves the coverage data and performance index data, and generates a coverage abnormality signal when any data item in the coverage data is not within the preset standard threshold range; and generates a performance index abnormality signal when any data item in the performance index data is not within the preset standard threshold range; Unqualified detectors that only generate coverage abnormality signals will be relocated and installed; unqualified detectors that only generate performance index abnormality signals will have their specifications replaced; unqualified detectors that generate both coverage abnormality signals and performance index abnormality signals will have their specifications replaced and relocated and installed at the same time.

[0009] Furthermore, fire characteristic data include smoke concentration, temperature value, combustion product concentration, flame heat release rate, and heat flux in the detection area; regional characteristic data include environmental indicators, combustible material indicators, electrical system indicators, and fire extinguishing indicators.

[0010] Furthermore, the fire detection module performs fire risk correlation prediction analysis including: Compare all regional characteristic data items with the corresponding regional characteristic standard ranges one by one. When all regional characteristic data items are within the preset standard range, a regional characteristic no-risk signal is generated; otherwise, a regional characteristic risk signal is generated. All fire characteristic data items are compared with the corresponding fire characteristic standard ranges one by one. When all fire characteristic data items do not exceed the preset standard range, a fire characteristic no-risk signal is generated. When any data item in the fire characteristic data items exceeds the preset standard range, a fire characteristic primary risk signal is generated. A fire characteristic risk curve is drawn with the collection time as the x-axis and the real-time collected fire characteristic data items as the measured value as the y-axis. When more than two of the fire characteristic data in all fire characteristic risk curves show an increasing trend, a fire characteristic special risk signal is generated.

[0011] Furthermore, the fire detection module generates a no fire hazard signal, a third-level risk warning signal, a second-level risk warning signal, or a first-level risk warning signal based on a comprehensive evaluation of multiple risk signals.

[0012] Furthermore, the determination process of whether to initiate a fire control instruction includes: when the fire management platform receives a signal indicating no fire hazard, it does not initiate a fire control instruction; when it receives a level 3 risk warning signal, it initiates a low-risk alarm instruction; when it receives a level 2 risk warning signal or a level 1 risk warning signal, it initiates a high-risk execution instruction.

[0013] The present invention also provides a fire detection alarm fire fighting linkage control method, comprising the following steps: Step 1: Determine whether the detection facilities within the detection area meet the fire warning requirements. If not, divide the detection area into control areas and adjust the location and specifications of the detection facilities within the control areas. If they meet the requirements, proceed to step 2. 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 risk level results; Step 3: Determine whether to initiate a fire control instruction based on the risk level results, and take execution measures when the fire control instruction is initiated.

[0014] Compared with the prior art, the advantages of the present invention are: 1. The present invention realizes the linkage control of fire response through the closed-loop association path of "detection-decision-execution". For the "detection-decision" link, through standardized multi-source acquisition of facility information, it is judged whether the detection facilities meet the fire warning requirements, improves the reliability and timeliness of the acquisition of trigger source information of the fire linkage system, and reduces the risk of false alarms and missed alarms. Through standardized multi-source acquisition of fire characteristic data and regional characteristic data, the fire risk is predicted and analyzed by combining internal and external quantitative evaluation indicators with logical diagnosis models, which can systematically improve the reliability of fire warning diagnosis, thereby reducing the difficulty of subsequent fire rescue.

[0015] 2. Based on the above content, analyze the facility information of all fire detectors in the detection area to determine whether the detection facilities meet the fire warning requirements. If not, divide the detection area into control areas, and adjust the position and specifications of the detection facilities in the control areas to ensure that the fire control performance in the fire monitoring area can meet the actual regional needs. The detection accuracy determines the reliability and timeliness of the warning response.

[0016] 3. Coordinated regional environmental impacts to conduct correlation prediction and analysis on fire risks. Comprehensive risk classification and logical diagnosis determine the reliability of fire protection execution. Closed-loop control can dynamically match fire risk levels with execution measures. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 This is a system principle block diagram of the present invention; Figure 2 This is a logic block diagram of the method of the present invention. DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work shall fall within the scope of protection of the present invention.

[0019] Example 1: The present invention discloses a fire detection alarm fire fighting linkage control system, please refer to Figure 1 、 Figure 2 , including fire management platform, detection equipment management module, fire detection module, early warning control module, alarm response module and fire control module; The fire management platform is used to divide the building site into multiple detection areas and obtain the detection facilities within the detection areas. The detection facilities include all different types of fire detectors and are numbered one by one.

[0020] The detection equipment management module is used to collect the facility information of all fire detectors in the detection area and determine whether the detection facilities meet the fire warning requirements based on the facility information. The specific judgment process includes: Obtain facility information for each fire detector, including coverage data and performance indicator data. Coverage data includes the fire detector's protection radius and applicable height, while performance indicator data includes the fire detector's allowable pressure difference, monitoring current, and response time. Compare and analyze each data item in the facility information with a preset standard data threshold. When each data item in the facility information of the 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 judged that the detection facilities in the detection area meet the fire warning requirements and a fire warning qualified signal is generated. Otherwise, it is judged that the detection facilities in the detection area do not meet the fire warning requirements and a fire warning control signal is generated. The overall warning performance of the fire detector is judged from two aspects: coverage data and performance index data. If it meets the coverage arrangement requirements and the performance requirements itself, it is considered reasonable. Otherwise, the number, position or specifications need to be adjusted. Fire detectors with excellent performance and correct layout can ensure the rapid transmission of fire signals and shorten the response time, so as to improve the reliability of the trigger source information collection of the fire linkage system and reduce the risk of false alarms and missed alarms.

[0021] The generated fire warning qualified signal and fire warning control signal are sent to the fire detection module and the warning control module respectively.

[0022] The early warning control module responds to the fire early warning control signal, divides the detection area corresponding to the fire early warning control signal into a control area, and adjusts the position and specifications of the detection facilities in the control area. The specific process includes: Obtain the number and location of unqualified detectors in 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 anomaly signal is generated; when any data item in the performance index data is not within the preset standard threshold range, a performance index anomaly signal is generated; Unqualified detectors that only generate coverage abnormality signals will be relocated and installed, unqualified detectors that only generate performance index abnormality signals will have their specifications replaced, unqualified detectors that generate both coverage abnormality signals and performance index abnormality signals will have their specifications replaced and relocated at the same time, and unqualified detectors in the control area will have their positions and specifications adjusted to ensure that the fire control performance in the fire monitoring area can meet the actual regional needs, so as to improve detection accuracy. Detection accuracy determines the reliability and timeliness of early warning response, reducing the risk of false alarms and missed alarms.

[0023] The fire detection module responds to the fire warning qualified signal and collects the fire characteristic data and regional characteristic data of the detection area; Among them, fire characteristic data include smoke density, 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 firefighting 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 the combustible material itself. When combustible materials are concentrated in a large continuous space, the fire load is high, and the stacking density is too large, such as when cargo piles exceed the height of the fire passage, it will hinder evacuation and firefighting. The combustible material critical value indicates 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, the scale and spread of the fire will be increased. Electrical system indicators include the number of electrical equipment and the historical frequency of electrical equipment failures. Old lines, overloaded electricity, and short-circuit failures are the main causes of electrical fires. Firefighting indicators include the number of fire hydrants and the coverage radius of fire hydrants, reflecting the coverage rate of firefighting equipment. The fire detection module combines fire characteristic data and regional characteristic data to conduct fire risk correlation prediction analysis on the detection area, and sends the obtained risk level results to the fire management platform; The process of fire risk correlation prediction analysis includes: comparing all regional characteristic data items with the corresponding regional characteristic standard ranges one by one. When all regional characteristic data items are within the preset standard range, a regional characteristic no-risk signal is generated; otherwise, a regional characteristic risk signal is generated. All fire characteristic data items are compared with the corresponding fire characteristic standard ranges one by one. When all fire characteristic data items are within the preset standard range, a fire characteristic no-risk signal is generated. When any one of the fire characteristic data items exceeds the preset standard range, a fire characteristic primary risk signal is generated. A fire characteristic risk curve is drawn with the collection time as the x-axis and the real-time collected fire characteristic data items as the measured values ​​as the y-axis. When any two of the fire characteristic data in all the fire characteristic risk curves show an increasing trend, a fire characteristic special risk signal is generated. Based on the comprehensive evaluation of the above-mentioned multiple risk signals, a fire hazard-free signal, a third-level risk warning signal, a second-level risk warning signal, or a first-level risk warning signal is generated respectively. The fire hazard-free signal, the third-level risk warning signal, the second-level risk warning signal, and the first-level risk warning signal are sent to the fire management platform as risk level results. By collecting fire characteristic data and regional characteristic data from standardized multiple sources, the fire risk is predicted and analyzed using both internal and external quantitative evaluation indicators combined with a logical diagnosis model, which can systematically improve the reliability of fire early warning diagnosis. The comprehensive evaluation process of multiple risk signals is as follows: when the regional characteristic no-risk signal and the fire characteristic no-risk signal are generated at the same time, a no-fire hazard signal is generated; when the regional characteristic no-risk signal and the fire characteristic primary risk signal are generated at the same time, or the regional characteristic risk signal and the fire characteristic no-risk signal are generated at the same time, a third-level risk warning signal is generated; when the regional characteristic risk signal and the fire characteristic primary risk signal are generated at the same time, or the regional characteristic no-risk signal and the fire characteristic special risk signal are generated at the same time, a second-level risk warning signal is generated; when the regional characteristic risk signal and the fire characteristic special risk signal are generated at the same time, a first-level risk warning signal is generated.

[0024] Example 2: Please refer to Figure 1-Figure 2 ,The fire management platform determines whether to start the fire control instruction based on the risk level results.,The fire control instruction includes low-risk alarm instruction and high-risk execution instruction; 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 a fire control instruction. 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 instruction. 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, initiates a high-risk execution instruction, and sends the low-risk alarm instruction and high-risk execution instruction to the fire control module. The fire control module responds to low-risk execution instructions and high-risk execution instructions, and respectively makes low-risk execution measures and high-risk execution measures. The closed-loop control can dynamically match the fire risk level and the execution measures. The specific process is as follows: When the fire control module responds to a low-risk alarm command, it takes low-risk execution measures, automatically activates sound and light alarms and closes fire doors in low-risk fire areas, and sends a three-level risk warning signal to management personnel, who then organize orderly evacuation of personnel. When the fire control module responds to a high-risk execution instruction, it takes high-risk execution measures. For high-risk fire areas, it automatically activates the sound and light alarm, closes the fire doors, automatically opens the fire hydrants or fire extinguishing systems, and sends a second-level risk warning signal or a first-level risk warning signal to management personnel and firefighters. Management personnel organize the orderly evacuation of personnel, and firefighters organize firefighting activities.

[0025] Embodiment 3: In combination with Embodiments 1 and 2, the present invention further proposes a fire detection alarm and fire fighting linkage control method, comprising the following steps: Step 1: Collect the facility information of all fire detectors in the detection area and determine whether the detection facilities in the detection area meet the fire warning requirements. If not, divide the detection area into control areas and adjust the location and specifications of the detection facilities in the control areas. If they meet the requirements, proceed to step 2. 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 risk level results; Step 3: Determine whether to initiate a fire control instruction based on the risk level results. The fire control instruction includes a low-risk alarm instruction and a high-risk execution instruction. When a low-risk alarm instruction is initiated, a low-risk execution measure is taken. When a high-risk alarm instruction is initiated, a high-risk execution measure is taken.

[0026] It should be added here that the multiple types of thresholds involved in the article, thresholds or preset values, preset ranges, etc. are set for result comparison and analysis in order to determine whether they are good or bad. The value of each threshold is set for entry and storage based on a combination of large-scale model analysis of sample data and manual experience, and can also be appropriately adjusted based on seasonal or common sense influencing conditions.

[0027] In summary, the solution is constructed from the detection end, the control end, and the execution end, and the fire response linkage control is realized through the "detection-decision-execution" closed-loop association path. Especially for the "detection-decision-making" link, through standardized multi-source collection of facility information, it is judged whether the detection facilities meet the fire warning requirements, improve the reliability of the fire linkage system's trigger source information acquisition, and reduce the risk of false alarms and missed alarms. Through standardized multi-source collection of fire characteristic data and regional characteristic data, the fire risk is predicted and analyzed by combining internal and external quantitative evaluation indicators with intelligent diagnosis models, which can systematically improve the reliability of fire warning diagnosis and thus reduce the difficulty of subsequent firefighting and rescue.

[0028] Among them, detection accuracy determines the reliability and timeliness of early warning response, risk logic diagnosis determines the reliability of fire execution, and the response of execution equipment to execution signals determines the fire extinguishing effect.

[0029] The above description is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved conception of the present invention shall be covered within the protection scope of the present invention.
