Technical Field
[0001] This invention relates to the field of fire protection and security technology, and in particular to an intelligent rapid response area fire extinguishing system. Background Technology
[0002] A fire suppression system is a comprehensive safety system composed of a series of devices, components, and measures. Designed and installed in buildings or other specific locations, its core function is to monitor fire signs (such as smoke and abnormal temperatures) in real time, automatically or manually, and to quickly extinguish fires and suppress their spread using extinguishing agents (such as water, foam, gas, or dry powder) or other physical and chemical means, thereby maximizing the protection of people's lives and property. Once a fire breaks out in a company's storage warehouse, the fire spreads rapidly and can cause irreversible damage in a very short time. Traditional fire sprinkler technology typically takes 30 seconds to several minutes from detecting a fire signal to confirming the fire and activating the fire suppression system. This delay may cause the company to miss the optimal window for fighting the fire in its early stages (especially electrical and oil fires).
[0003] Therefore, an intelligent and rapid response area fire extinguishing system was invented. Based on the company's existing intelligent safety management system AI algorithm module and personnel positioning module as input judgment conditions, and with the help of personnel positioning system and AI camera, it can identify the properties of materials stored in different areas and spray different media, providing favorable conditions for extinguishing initial fires. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing fire sprinkler technology, which typically takes 30 seconds to several minutes from detecting a fire signal to confirming the fire and activating the fire extinguishing device. This delay may cause the best window for extinguishing the fire to be missed in the early stages of a fire (especially electrical fires and oil fires). The present invention provides an intelligent rapid response area fire extinguishing system.
[0005] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is to provide an intelligent rapid response area fire extinguishing system, including a personnel positioning module, a panel unit, an AI camera, an intelligent rapid response area fire extinguishing system controller, and an alarm module; The personnel positioning module identifies the personnel situation in the warehouse area through a preset terminal. When there is a manager in the warehouse area, it generates a first signal to the intelligent rapid response area fire extinguishing system controller. The panel unit is used to set the permissions of management personnel. When a management personnel with the specified permissions enters the warehouse area, a second signal is triggered to the intelligent rapid response area fire extinguishing system controller. AI cameras are deployed at the entrance roller shutter doors and interior areas of the warehouse area to identify abnormal situations in the warehouse area and generate a third signal to the controller of the intelligent rapid response area fire extinguishing system. The intelligent rapid response area fire extinguishing system controller receives the first signal, the second signal and the third signal, controls the opening and closing operation of the entrance roller shutter door of the warehouse area according to the preset logical judgment conditions, and generates a judgment result based on the first signal and the second signal, and converts the judgment result into a control command and sends it to the preset automatic sprinkler fire extinguishing system.

It also includes a manual alarm module, a linkage module, a signal access module, and a manual control module; The manual alarm module is used to receive manual alarm signals from management personnel and transmit them to the intelligent rapid response area fire extinguishing system controller. The linkage module, based on the control command of the intelligent rapid response area fire extinguishing system controller, activates the preset automatic sprinkler system to select the medium for spraying fire extinguishing. The signal access module is used to access the fire alarm lights and safety exit signals of the surrounding area of the warehouse area and transmit them to the intelligent rapid response area fire extinguishing system controller. The manual control module is used to receive manual input signals from management personnel and transmit them to the intelligent rapid response area fire extinguishing system controller.
[0007] The present invention is further configured such that: the preset terminal in the personnel positioning module includes a base station and a personnel positioning beacon network, and identifies whether there are management personnel in the warehouse area based on the base station and personnel positioning beacon network; When a manager is present in the warehouse area, the intelligent security management unit preset in the personnel positioning module generates a first signal. The steps for generating the first signal are as follows: S1. Based on the network of base stations and personnel positioning beacons, calculate the real-time location coordinates of personnel in the warehouse area, identify personnel identity tags, and generate personnel presence status data; S2. Based on the personnel presence status data, the intelligent security management unit analyzes the personnel activity trajectory and dwell time, and matches the personnel identity with the preset management personnel permission database. When the presence of management personnel is detected and the activity trajectory conforms to the preset work mode, a personnel confirmation signal is generated. S3. Based on the personnel confirmation signal, the material property confirmation component in the intelligent safety management unit calls the material database in the warehouse area, and the management personnel confirm the material properties based on on-site observation or preset equipment input, generating material property data; S4. Based on the personnel confirmation signal and the material property data, generate a first signal and transmit it to the intelligent rapid response area fire extinguishing system controller.
[0008] The present invention is further configured such that: the second signal in the panel device specifically includes the manager's identity identifier, entry timestamp, and permission level information generated based on the permission verification result; when a manager with the permission performs identity authentication through the panel device and the verification is successful, the panel device collects the manager's identity data and entry time in real time, encapsulates the permission verification result and timestamp into a data packet through the built-in microprocessor, and generates a second signal in combination with a preset permission level database; the second signal is transmitted to the intelligent rapid response area fire extinguishing system controller through a wired or wireless communication protocol.
[0009] The present invention is further configured such that the generation steps of the third signal in the AI camera are as follows: Q1. Based on the AI camera, real-time thermal imaging video streams of the warehouse area's entrance roller shutter door and internal area are collected. The contrast and clarity of the thermal imaging video streams are enhanced through image preprocessing algorithms, and key frame sequences are extracted to generate an initial image dataset. Q2. Based on the initial image dataset, analyze the moving objects in the initial image dataset, identify the behavior of managers and vehicles entering the warehouse area, and record their location coordinates, quantity statistics and movement trajectory characteristics to generate an object recognition result set; Q3. Based on the object recognition result set and combined with the temperature distribution data in the thermal imaging video stream, when the temperature in the warehouse area exceeds the preset safety threshold or flame morphology features are detected, a fire confirmation signal is generated. Q4. Based on the object identification result set and the fire confirmation signal, the management personnel entry event, vehicle entry event and fire occurrence event are integrated, encapsulated into a standardized alarm data packet, a third signal is generated, and transmitted to the intelligent rapid response area fire extinguishing system controller through a wired or wireless communication protocol.
[0010] The present invention is further configured such that: the specific content of controlling the opening and closing operation of the entrance roller shutter door of the warehouse area by the intelligent rapid response area fire extinguishing system controller according to preset logical judgment conditions is as follows: W1. Based on the first signal, the second signal and the third signal received by the intelligent rapid response area fire extinguishing system controller, analyze the personnel presence status in the first signal, the verification result of the permission in the second signal and the abnormal event identifier in the third signal to generate a comprehensive risk assessment index. W2. Based on the comprehensive risk assessment index, a preset roller shutter door control strategy is matched. When the safety level indicated by the comprehensive risk assessment index is lower than the preset safety threshold and the second signal verification permission is passed, a roller shutter door opening command is generated. When the safety level indicated by the comprehensive risk assessment index exceeds the preset safety threshold or the third signal detects a fire, a roller shutter door closing command is generated. W3. The roller shutter door opening command or roller shutter door closing command is transmitted to the actuator of the imported roller shutter door in the warehouse area to trigger the opening and closing operation of the roller shutter door, and the operation status is fed back to the intelligent rapid response area fire extinguishing system controller in real time.
[0011] The present invention is further configured such that the steps for generating the determination result in the intelligent rapid response area fire suppression system controller are as follows: W4. Based on the personnel confirmation signal and material property data in the first signal, and the management personnel identity, entry timestamp and permission level information in the second signal, the personnel presence status, material characteristics and permission verification results are weighted and integrated to calculate a preliminary risk score. W5. Based on the preliminary risk score and combined with the real-time environmental parameters of the warehouse area, when the preliminary risk score exceeds the preset action threshold, a fire extinguishing command is generated; when the preliminary risk score is lower than the preset action threshold, a monitoring and maintenance command is generated. The fire extinguishing command and the monitoring and maintenance command are used as the judgment result.
[0012] The present invention is further configured such that the specific steps in the intelligent rapid response area fire suppression system controller for converting the determination result into control commands are as follows: W6. Based on the fire extinguishing command or the monitoring and maintenance command in the determination result, generate a set of control parameters; W7. Convert the control parameters in the control parameter set into standardized control commands, and transmit the control commands to the preset automatic sprinkler system in conjunction with wired or wireless communication protocols to trigger the corresponding fire extinguishing spray or monitoring and maintenance operations, and provide real-time feedback on the execution status to the intelligent rapid response area fire extinguishing system controller.
[0013] The present invention is further configured such that: when the intelligent rapid response area fire extinguishing system controller receives a second alarm signal from the sensor component, the signal access module, and the manual control module, it generates an audible and visual alarm signal through the audible and visual alarm device based on the first alarm signal and the second alarm signal, and simultaneously sends alarm information to relevant personnel through the SMS alarm device.
[0014] The beneficial effects of this invention are as follows: 1.

This invention utilizes comprehensive risk assessment indicators and preliminary risk scores to achieve graded and precise response. By dynamically determining whether to initiate a fire extinguishing command or a monitoring and maintenance command, and based on a set of control parameters, it precisely controls the spray medium and intensity of the automatic sprinkler system, significantly improving the effectiveness and safety of fire extinguishing operations and avoiding secondary losses caused by malfunctions.

Detailed Implementation
[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.
[0017] Please see Figure 1 - Figure 4 An intelligent rapid response area fire suppression system includes a personnel positioning module, a panel unit, an AI camera, an intelligent rapid response area fire suppression system controller, and an alarm module. The personnel positioning module identifies the personnel situation in the warehouse area through preset terminals. When there are management personnel in the warehouse area, it generates the first signal to the intelligent rapid response area fire extinguishing system controller. The panel unit is used to set the permissions of management personnel. When an authorized management personnel enters the warehouse area, it triggers a second signal to the intelligent rapid response area fire suppression system controller. AI cameras are deployed at the entrance roller shutters and interior areas of the warehouse area to identify abnormal situations in the warehouse area and generate a third signal to the intelligent rapid response area fire suppression system controller. The intelligent rapid response area fire extinguishing system controller receives the first signal, the second signal, and the third signal. Based on the preset logical judgment conditions, it controls the opening and closing operation of the entrance roller shutter door of the warehouse area using the second signal. It also generates a judgment result based on the first and second signals, and converts the judgment result into a control command to send to the preset automatic sprinkler fire extinguishing system. The intelligent rapid response area fire suppression system controller adopts advanced microprocessor technology and features high speed, stability, and reliability. At the same time, the intelligent rapid response area fire suppression system controller also supports remote communication functions, which can upload alarm information to the fire control center or the handheld devices of relevant management personnel via wired or wireless means. The alarm module includes an audible and visual alarm and an SMS alarm. When the intelligent rapid response area fire extinguishing system controller receives the first alarm signal from the AI camera, it generates an audible and visual alarm signal through the audible and visual alarm and sends alarm information to relevant personnel through the SMS alarm.
[0018] The beneficial effects of this system are that it enables real-time and accurate perception of personnel activities and abnormal fires in the warehouse area through the multi-source signal collaboration of personnel positioning module, panel machine and AI camera; the intelligent controller, based on the logical fusion of the first, second and third signals, quickly controls the opening and closing of the imported roller shutter door and triggers the automatic sprinkler system, and combined with the sound, light and SMS alarm module to achieve second-level response and closed-loop handling, significantly improving the efficiency of fire detection and the level of automation of emergency response, and ensuring the safety of the area.
[0019] Specifically, the system also includes smoke sensors, temperature sensors and fire emergency lights, which are deployed in the internal area of the warehouse area; Smoke and heat sensors are used to identify abnormal conditions in the warehouse area; fire emergency lights serve as the trigger condition for fire alarms in the warehouse area, and the signals are connected to the intelligent rapid response area fire extinguishing system controller. It also includes a manual alarm module, a linkage module, a signal access module, and a manual control module; The manual alarm module is used to receive manual alarm signals from management personnel and transmit them to the intelligent rapid response area fire suppression system controller. The linkage module, based on the control commands of the intelligent rapid response area fire extinguishing system controller, activates the preset automatic sprinkler system to select the optimal medium for spraying fire extinguishing, realizing cross-departmental linkage response; The linkage module, based on the "monitoring-alarm-response-assessment" model, achieves close cross-departmental and cross-system collaboration, significantly improving emergency response efficiency. Specifically, it adopts a three-tiered architecture of "perception-decision-execution," using fire signal triggering for logical configuration to establish the linkage mechanism. This mechanism ensures that in emergencies, relevant departments and systems can respond quickly, coordinate efforts, and jointly address sudden events, ensuring efficient and orderly handling. When the intelligent rapid response area fire suppression system controller receives alarm signals from smoke and heat sensors, signal access modules, manual control modules, or intelligent AI cameras and determines it to be a fire or other abnormal scenario, it immediately activates the linkage module, sending activation signals to fire suppression equipment such as automatic sprinkler systems via wired or wireless means. This allows the automatic sprinkler systems and other fire suppression equipment to quickly activate and begin operation, effectively controlling and extinguishing the fire. The signal access module is used to connect to the fire alarm lights and safety exit signals in the surrounding area of the warehouse area and transmit them to the intelligent rapid response area fire extinguishing system controller. The signal access module is used to connect to fire alarm lights and safety exit signals in the surrounding area. When an emergency such as a fire occurs in the surrounding area, the fire alarm lights and safety exit signals will emit alarm signals. After receiving these signals, the signal access module transmits them to the intelligent rapid response zone fire suppression system controller, which then determines whether to activate the roller shutter door body, alarm module, and linkage module. In this way, the system can seamlessly integrate with the fire protection equipment in the surrounding area, forming a more comprehensive fire prevention and control system. The manual control module is used to receive manual input signals from management personnel and transmit them to the intelligent rapid response area fire suppression system controller.
[0020] Preferably, the system also includes a power supply module to provide stable power support for the entire system. The power supply module employs a redundant design, offering both backup and main power supply options. When the main power supply fails, the backup power supply can immediately take over, ensuring the normal operation of the entire system. Simultaneously, the power supply module also supports battery charging and discharging management functions, automatically detecting battery level and performing charging or discharging operations to extend battery life.
[0021] One embodiment of the present invention is as follows: the preset terminal in the personnel positioning module includes a base station and a personnel positioning beacon network, and identifies whether there are management personnel in the warehouse area based on the base station and the personnel positioning beacon network; When there are management personnel present in the warehouse area, the intelligent safety management unit preset in the personnel positioning module generates a first signal as the first-level judgment of the material properties in the warehouse area. The generation steps of the first signal are as follows: S1. Based on the network of base stations and personnel positioning beacons, the real-time location coordinates of personnel in the warehouse area are calculated through signal strength detection and triangulation algorithms, and personnel identity tags (such as managers or ordinary employees) are identified to generate personnel presence status data. S2. Based on personnel presence status data, the intelligent safety management unit analyzes personnel activity trajectories and dwell times, and matches personnel identities with a preset management personnel permission database. When the presence of management personnel is detected and their activity trajectory matches the preset work mode, a personnel confirmation signal is generated. The preset management personnel permission database is an electronic database that stores management personnel identity information, permission levels, and access rules. It is used to match personnel identities through the intelligent security management unit, verify their access permissions and operation levels in the warehouse area, and ensure that only authorized management personnel trigger signals. Preset working mode: refers to the pre-set normal activity mode of management personnel, including typical working time periods, distribution of stay areas and movement trajectory characteristics. It is used to analyze personnel activity trajectories through intelligent safety management unit, determine whether the behavior complies with safety regulations, and avoid abnormal triggering. S3. Based on personnel confirmation signals, the material property confirmation component in the intelligent safety management unit calls the material database in the warehouse area. The management personnel confirm the material properties (such as flammability and toxicity level) based on on-site observation or preset equipment input, and generate material property data. Material property verification component: This is a dedicated module in the intelligent safety management unit. It is responsible for calling the material database in the warehouse area and allows managers to verify the material properties (such as flammability and toxicity level) based on on-site observation or equipment input, generating standardized material property data for risk assessment. The pre-set equipment specifically includes terminal devices for material property input, such as handheld scanners, touch screen interfaces, or sensor networks, allowing managers to input or automatically collect material data in real time, ensuring the accuracy and timeliness of property confirmation; S4. Based on personnel confirmation signals and material property data, generate a first signal and transmit it to the intelligent rapid response area fire extinguishing system controller.
[0022] This embodiment identifies management personnel in real time through a network of base stations and personnel positioning beacons. Combined with the analysis of activity trajectories and material properties by the intelligent safety management unit, a first signal is generated as a level-one judgment of fire risk, thereby improving the response accuracy and speed of the fire extinguishing system, reducing false alarms, and optimizing safety management efficiency.
[0023] One embodiment of the present invention is as follows: The second signal in the panel device specifically includes the manager's identity identifier, entry timestamp, and permission level information generated based on the permission verification result. When a qualified manager authenticates his / her identity through the panel device (such as by swiping a card, fingerprint, or password) and the verification is successful, the panel device collects the manager's identity data and entry time in real time. The built-in microprocessor encapsulates the permission verification result and timestamp into a data packet and combines it with a preset permission level database (such as the area access level corresponding to different permissions) to generate a second signal. The second signal is transmitted to the intelligent rapid response area fire extinguishing system controller through a wired or wireless communication protocol to trigger the opening and closing operation of the inlet roller shutter door and the subsequent collaborative processing of fire extinguishing decisions.
[0024] This embodiment uses a panel device for identity authentication (such as card swiping, fingerprint or password input), verifies the management personnel's permissions in real time, and generates a second signal containing identity identifier, entry timestamp and permission level information. The microprocessor encapsulates data packets and combines them with the permission level database to ensure accurate triggering of the opening and closing of the imported roller shutter door and the coordinated processing of fire extinguishing decisions, significantly improving system security, automation level and emergency response efficiency.
[0025] One embodiment of the present invention is as follows: The steps for generating the third signal in the AI camera are as follows: Q1. Based on AI cameras, real-time thermal imaging video streams of the warehouse area's entrance roller shutter door and internal area are collected. The contrast and clarity of the thermal imaging video stream are enhanced through image preprocessing algorithms, and key frame sequences are extracted to generate an initial image dataset. Q2. Based on the initial image dataset, analyze the moving objects in the initial image dataset using object recognition algorithms, identify the behavior of managers and vehicles entering the warehouse area, and record their location coordinates, quantity statistics and movement trajectory characteristics to generate an object recognition result set. Q3. Based on the object recognition result set and combined with the temperature distribution data in the thermal imaging video stream, when the temperature in the warehouse area exceeds the preset safety threshold or flame morphology features are detected, a fire confirmation signal is generated. The optimal value of the preset safety threshold is dynamically adjusted based on historical fire data and the characteristics of materials in the warehouse area. By statistically analyzing the temperature fluctuation range of common fires (such as 60°C to 80°C) and the ignition point characteristics of materials, the upper limit of temperature is set to 70°C. It is then fine-tuned in combination with real-time environmental factors (such as ventilation conditions) to ensure that the threshold can sensitively detect fires while avoiding false alarms caused by environmental interference. Q4. Based on the object recognition result set and the fire confirmation signal, the event fusion algorithm integrates the management personnel entry event, vehicle entry event and fire occurrence event, encapsulates them into a standardized alarm data packet, generates a third signal, and transmits it to the intelligent rapid response area fire extinguishing system controller through wired or wireless communication protocols.
[0026] This embodiment uses an AI camera to collect thermal imaging video streams in real time. After image preprocessing and object recognition algorithms, it accurately detects personnel, vehicles entering and fires. Combined with temperature threshold judgment, it generates a fire confirmation signal and encapsulates a third signal through event fusion, thereby improving the real-time performance, accuracy and system response efficiency of fire detection and reducing false alarms and missed alarms.
[0027] One embodiment of the present invention is as follows: The specific content of the intelligent rapid response area fire suppression system controller controlling the opening and closing operation of the warehouse area's entrance roller shutter door according to preset logical judgment conditions is as follows: W1. Based on the first, second, and third signals received by the intelligent rapid response area fire extinguishing system controller, analyze the personnel presence status in the first signal, the authorization verification results in the second signal, and the abnormal event identifiers in the third signal to generate a comprehensive risk assessment index. The comprehensive risk assessment index quantifies the real-time security level of the warehouse area. The steps for generating comprehensive risk assessment indicators are as follows: Based on the first signal (personnel presence status), the second signal (authorization verification result), and the third signal (abnormal event identifier) received by the intelligent rapid response area fire extinguishing system controller, the weight of personnel status, authorization verification level, and severity of abnormal events are weighted and calculated using a multi-source data fusion algorithm. The weight values are dynamically adjusted based on historical fire data and expert experience, and finally, a quantitative comprehensive risk assessment indicator is generated to characterize the safety level of the warehouse area in real time. W2. Based on the comprehensive risk assessment index, match the preset roller shutter door control strategy. When the safety level indicated by the comprehensive risk assessment index is lower than the preset safety threshold and the second signal verification authority is passed, generate the roller shutter door opening command. When the safety level indicated by the comprehensive risk assessment index exceeds the preset safety threshold or the third signal detects a fire, generate the roller shutter door closing command. The preset roller shutter door control strategy includes automatic linkage control, manual remote control, and hierarchical linkage strategy. Specifically, when the comprehensive risk assessment indicator indicates that the safety level is lower than the preset safety threshold and the second signal verification authority is passed, the roller shutter door opening command is triggered; when the safety level exceeds the preset safety threshold or the third signal detects a fire, the roller shutter door closing command is triggered; for large warehouse areas, a phased activation strategy can also be adopted, prioritizing the closure of roller shutter doors near the fire source and then gradually expanding to balance evacuation and fire prevention needs. W3 transmits the opening or closing command of the roller shutter door to the actuator of the imported roller shutter door in the warehouse area, triggering the opening and closing operation of the roller shutter door, and feeding back the operation status to the intelligent rapid response area fire extinguishing system controller in real time, forming a closed-loop control from signal analysis to mechanical execution.
[0028] Preferably, the steps for generating the judgment result in the intelligent rapid response area fire suppression system controller are as follows: W4. Based on the personnel confirmation signal and material property data in the first signal, and the management personnel identification, entry timestamp and permission level information in the second signal, the personnel presence status, material characteristics and permission verification results are weighted and integrated to calculate a preliminary risk score. The preliminary risk score quantifies the immediate security threat level of the warehouse area. The calculation steps for the preliminary risk score are as follows: Based on the personnel confirmation signal and material property data in the first signal, and the management personnel identification and permission level information in the second signal, a weighted fusion algorithm is used. Specifically, the preliminary risk score is equal to the personnel presence status weight multiplied by the personnel status value, plus the material characteristic weight multiplied by the material hazard coefficient, plus the permission verification weight multiplied by the permission level value. The weights are calibrated based on the historical fire statistics of the warehouse area and real-time environmental parameters to ensure that the score accurately quantifies the immediate safety threat level. W5. Based on the preliminary risk score and combined with the real-time environmental parameters of the warehouse area (such as temperature distribution data extracted from the third signal or historical operation records), when the preliminary risk score exceeds the preset action threshold, a fire extinguishing command is generated; when the preliminary risk score is lower than the preset action threshold, a monitoring and maintenance command is generated. The fire extinguishing command and the monitoring and maintenance command are used as the judgment results.
[0029] The optimal value of the preset action threshold is determined by analyzing historical fire data of the warehouse area, the flammability of materials, and environmental factors (such as ventilation conditions). For example, for a warehouse storing flammable materials, the action threshold is set to a risk score of 70 (out of 100). When the score exceeds 70, the fire extinguishing command is automatically triggered. When it is below 70, the monitoring command is maintained. This value has been verified by simulation to balance the false alarm rate and response efficiency. The specific contents of the fire extinguishing and monitoring maintenance commands are as follows: The specific instructions for activating the fire extinguishing system include: controlling the automatic sprinkler system to select the spray medium (such as water or foam), setting the spray intensity to high-pressure mode, setting the duration to 10 minutes, and triggering the alarm module to issue an audible and visual warning; the instructions for monitoring and maintaining the system include: keeping the sensors continuously monitoring, recording environmental data periodically, not activating the fire extinguishing equipment, and only recording risk changes through the log. Preferably, the specific steps in the intelligent rapid response area fire suppression system controller for converting the judgment result into control commands are as follows: W6. Based on the judgment result, the fire extinguishing command or monitoring and maintenance command is analyzed and the real-time environmental parameters of the warehouse area (such as temperature distribution data or historical operation records extracted from the third signal) are analyzed to generate a set of control parameters, including the type of spray medium, spray intensity and duration. W7 converts the control parameters in the control parameter set into standardized control commands, and transmits the control commands to the preset automatic sprinkler system in conjunction with wired or wireless communication protocols, triggering the corresponding fire extinguishing spray or monitoring and maintenance operations, and providing real-time feedback on the execution status to the intelligent rapid response area fire extinguishing system controller, forming a closed-loop control from command generation to equipment execution.
[0030] The specific steps for converting control parameters in a control parameter set into standardized control commands are as follows: the control parameter set (such as spray medium type, spray intensity and duration) is mapped to a standard industrial communication protocol (such as Modbus-TCP) through a protocol conversion module, the device address code and check code are added and encapsulated into a data packet, and then transmitted to the controller of the automatic sprinkler system via wired Ethernet or wireless Wi-Fi to ensure that the command can be parsed and trigger the corresponding actuator.
[0031] Example: In a warehouse area application, the personnel positioning module detects the presence of management personnel via base station beacons, generating a first signal (including personnel status and material properties). After the panel device verifies permissions, it triggers a second signal. When the AI camera monitors in real time and there is no fire, it generates a third signal. The controller integrates the three signals to generate a comprehensive risk assessment index (e.g., a safety level of 60 points). If the score is below the threshold of 70 and the permissions are granted, it triggers a roller shutter door opening command. If the AI camera suddenly detects that the temperature exceeds the threshold and the index rises to 80 points, it immediately closes the roller shutter door and initiates a fire extinguishing command based on the risk score, controlling the sprinkler system to spray high-pressure foam medium for 10 minutes, and providing real-time feedback on the operation status to form a closed loop.
[0032] This example achieves intelligent opening and closing of roller shutter doors and precise fire suppression response through multi-source signal fusion and dynamic risk assessment, improving the speed and accuracy of fire response. Closed-loop control enhances system reliability and effectively protects warehouse safety.
[0033] One embodiment of the present invention is as follows: the alarm module further includes, when the intelligent rapid response area fire extinguishing system controller receives the second alarm signal from the sensor component, the signal access module, and the manual control module, generating an audible and visual alarm signal through an audible and visual alarm based on the first alarm signal and the second alarm signal, and simultaneously sending alarm information to relevant personnel through an SMS alarm.
[0034] This embodiment integrates the second alarm signal from the sensor components, signal access module, and manual control module with the first alarm signal through an intelligent rapid response area fire suppression system controller. This enables multi-source signal collaborative verification, reduces the risk of false alarms, and quickly sends alarm information to relevant personnel through audible and visual alarms and SMS alarms, thereby improving alarm accuracy, reliability, and emergency response speed.
[0035] The above are merely embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
