Description

Technical Field

[0001] This disclosure pertains to the field of sprinkler fire suppression technology, and more specifically, relates to a control method and device for a sprinkler system. Background Technology

[0002] As people's living standards continue to improve, the number of cars on the road is gradually increasing. Underground parking lots in residential areas and shopping malls are the main places for parking vehicles. Once a fire breaks out, if it cannot be extinguished in time, the vehicles will burn fiercely, endangering people's lives and causing a lot of property damage. In some cases, it may even cause unavoidable damage to the building.

[0003] Currently, most of the aforementioned areas are equipped with sprinkler systems for fire suppression. However, in the event of a fire, most existing sprinkler systems spray a fixed amount of water, which is insufficient to cope with changing fire conditions, resulting in low fire suppression efficiency. Summary of the Invention

[0004] The purpose of this disclosure is to provide a control method and device for a sprinkler system to better extinguish fires in parking areas.

[0005] A first aspect of this disclosure provides a control method and a device detection method for a sprinkler system. The sprinkler system includes a first detection module, a second detection module, a central control module, and a sprinkler module. The central control module is connected to the first detection module, the second detection module, and the sprinkler module. The control method is applied to the central control module and includes: Based on the first information, it is determined whether there is at least one first area in the target area. The first information is the environmental information of the target area collected by the first detection module. The at least one first area includes the fire area in the target area. In response to the existence of at least one first area in the target area, the fire extinguishing priority of each first area is determined based on multiple second information, wherein the multiple second information are image information of the at least one first area collected by the second detection module. Based on the fire extinguishing priority, the sprinkler module is controlled to extinguish the fire in the at least one first area in sequence.

[0006] A second aspect of this disclosure provides a control method and a detection device for a sprinkler system. The sprinkler system includes a first detection module, a second detection module, a central control module, and a sprinkler module. The central control module is connected to the first detection module, the second detection module, and the sprinkler module. The control device is applied to the central control module and includes: The judgment unit is used to determine whether there is at least one first area in the target area based on the first information, wherein the first information is the environmental information of the target area collected by the first detection module, and the at least one first area includes the fire area in the target area. A calculation unit is configured to, in response to the existence of at least one first region in the target area, determine the fire extinguishing priority of each first region based on multiple second pieces of information, wherein the multiple second pieces of information are image information of the at least one first region collected by the second detection module. The control unit is used to control the sprinkler module to extinguish fires in the at least one first area sequentially based on the fire extinguishing priority.

[0007] A third aspect of this disclosure provides a control system for a sprinkler system, including a memory, a processor, and a computer program stored in the memory and running on the processor, wherein the processor executes the computer program to implement the steps of the above-described control method for the sprinkler system.

[0008] In a fourth aspect, this disclosure provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the above-described control method and device detection method for a sprinkler system.

[0009] The beneficial effects of the control method and apparatus for the sprinkler system provided in this disclosure are as follows: This application identifies the fire zone and determines the fire suppression priority for the first zone based on fire information. Fire suppression is then carried out on the target area based on this priority. When the fire suppression system's water supply is insufficient, the order and intensity of fire suppression are determined by assessing the actual conditions of the fire zones. This ensures that, even with insufficient water supply, the highest priority fire zone receives the most intensive fire suppression efforts, minimizing potential damage. Attached Figure Description

Detailed Implementation

[0012] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, so as to provide a thorough understanding of the embodiments of this disclosure. However, those skilled in the art will understand that this disclosure may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this disclosure with unnecessary detail.

[0013] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following description will be provided in conjunction with the accompanying drawings and specific embodiments.

[0014] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a control method for a sprinkler system according to an embodiment of the present disclosure. The sprinkler system includes a first detection module, a second detection module, a central control module, and a sprinkler module. The central control module is connected to the first detection module, the second detection module, and the sprinkler module. The control method is applied to the central control module, and the method includes: S101: Determine whether there is at least one first area in the target area based on the first information, wherein the first information is the environmental information of the target area collected by the first detection module, and the at least one first area includes the fire area in the target area; The target area is the area where the sprinkler system in this embodiment is installed for detection and spraying operations. The target area can be a parking lot, shopping mall, or warehouse, etc. To detect the fire situation in the target area, it is necessary to monitor the first information of the target area in real time. This first information includes temperature, humidity, smoke concentration, visible light and infrared spectrum information, and gas composition information. This first information can be detected by first detection devices, such as smoke sensors, humidity sensors, temperature sensors, gas sensors, and infrared sensors. If a fire area is detected within the target area, then that fire area is determined to be the first area.

[0015] In this embodiment, the first detection module is responsible for collecting environmental information about the target area. This information may include, but is not limited to, temperature, humidity, smoke concentration, gas composition (such as carbon monoxide and carbon dioxide concentrations), visible light and infrared light images, etc. After receiving the sensor data, the central control module analyzes the environmental information provided by the first detection module. By looking for abnormal data patterns, such as a sudden increase in temperature, an increase in smoke concentration, or abnormal concentrations of specific gases, and through comprehensive analysis of these abnormal data, it can determine whether a fire has occurred in the target area. If the central control module determines that a fire has occurred in the target area, it marks the fire area as the first area.

[0016] For example, if the target area is a parking lot, and the first detection module in the parking lot detects a car on fire, then the area near that car becomes the first zone. If two cars are on fire in the parking lot, then the area near each car becomes a first zone, meaning the parking lot has two first zones. S102: In response to the existence of at least one first area in the target area, the fire extinguishing priority of each first area is determined based on multiple second information, wherein the multiple second information are image information of the at least one first area collected by the second detection module.

[0017] The second information is image information of the first area, which can be obtained through image sensing devices (such as surveillance cameras). Firefighting priorities are determined based on personnel and vehicle information obtained from the second information.

[0018] In this embodiment, if at least one first area, i.e., a fire area appears in the target area, the second detection module collects image information of the first area. The image information includes the number and distribution of people and the number and distribution of vehicles.

[0019] Because ensuring personnel safety is the top priority during firefighting, the firefighting priority for the first area where personnel are present is higher than that for the first area where no personnel are present. Furthermore, since vehicles in parking lots are generally valuable, and vehicle fires could lead to explosions, exacerbating the fire and increasing the difficulty of firefighting, the firefighting priority for the first area where vehicles are present is higher than that for the first area where no vehicles are present. Therefore, based on the above experience, a firefighting priority determination method is pre-set: if the image information of the first area shows both personnel and vehicles, then the priority of the first area is recorded as first priority; if the image information of the first area shows personnel but no vehicles, then the priority of the first area is recorded as second priority; if the image information of the first area shows no personnel but vehicles, then the priority of the first area is recorded as third priority; and if the image information of the first area shows no personnel and no vehicles, then the priority of the first area is recorded as fourth priority.

[0020] The purpose of fire suppression priority is to determine which fire suppression measures should be implemented based on the water supply system if the water volume is insufficient during a fire.

[0021] S103: Based on the fire extinguishing priority, control the sprinkler module to sequentially extinguish the fire in the at least one first area. The sprinkler module can spray water to extinguish fires in the area on fire.

[0022] In this embodiment, based on a determined fire suppression priority, the sprinkler system will control the sprinkler modules to carry out orderly fire suppression in each first zone according to a predetermined strategy. When the water supply can meet the water needs of multiple first zones, the sprinkler volume of the first zone with a higher fire suppression priority is greater than that of the first zone with a lower fire suppression priority. When the water supply can only meet the water needs of some first zones, priority is given to sprinkling the areas with higher fire suppression priority.

[0023] For example, if there are two first zones, denoted as Zone 1 and Zone 2, Zone 1 has the highest fire extinguishing priority and Zone 2 has the second highest fire extinguishing priority. Only one zone can meet its water demand. Since Zone 1 has a higher fire extinguishing priority than Zone 2, Zone 1's water demand is supplied first.

[0024] Furthermore, if there are two first zones, denoted as Zone 1 and Zone 2, Zone 1 has the highest fire extinguishing priority and Zone 2 has the second highest fire extinguishing priority. This can meet the water demand of both zones. Since Zone 1 has a higher fire extinguishing priority than Zone 2, Zone 1 requires more water than Zone 2.

[0025] As can be seen from the above, this embodiment first needs to determine the area on fire, which is the first area. Then, it analyzes whether there are people and vehicles in the first area based on the sensor. Based on the information on the presence of people and vehicles, it determines the fire extinguishing priority of the first area and determines the water supply strategy of the water supply system based on the fire extinguishing priority.

[0026] This embodiment flexibly adjusts the fire strategy according to the actual fire situation, and prioritizes the safety of personnel and vehicles and property based on fire sensor information, thereby reducing fire losses.

[0027] In one embodiment of this disclosure, the control method for the sprinkler system includes: The fire type of each first area is determined based on the second information corresponding to each first area. The fire type includes a first fire type and a second fire type. The first fire type is the type in which people are present, and the second fire type is the type in which people are not present. In response to the fire type being classified as the first fire type in the first zone, the fire suppression priority for the first zone is set to the highest priority. In response to the fire type being classified as the second fire type in the first area, the fire suppression priority for that first area is the second priority.

[0028] Firstly, information is collected by sensors pre-installed in the target area, such as thermal imaging data from infrared detectors or mobile phone cameras, and video surveillance images. Image information of the first area is obtained through analysis of thermal imaging data and video surveillance images, and personnel and vehicle information is identified in the image information by a calculator. The computer then classifies the fire information in the first area into two types: a first fire type (indicating the presence of people) and a second fire type (indicating the absence of people).

[0029] In this embodiment, the safety of personnel is the top priority. For the first type of fire, i.e., the area containing personnel within the first zone, the system will automatically set its fire suppression priority to first priority. This means that the area of ​​the first type of fire will receive the most rapid and full-force fire suppression response, ensuring that the fire is controlled as quickly as possible, creating safe conditions for personnel evacuation and rescue. For the second type of fire, since no personnel are directly in danger, the fire suppression priority for this first zone is set to second priority. Although the first zone has a lower priority, this does not mean that it is unimportant. Rather, according to resource and strategic arrangements, fire suppression will be carried out in an orderly manner while ensuring the safety of the first priority areas.

[0030] Through this strategy, the system can rationally allocate limited fire-fighting resources, prioritize the protection of human life, effectively control the fire, and prevent the fire from spreading further, reflecting the humanistic priority and efficient use of resources in emergency situations.

[0031] In one embodiment of this disclosure, the control method for the sprinkler system includes: The second piece of information is input into the first prediction model to predict the amount of water required for fire extinguishing.

[0032] The first prediction model is a water demand prediction model. By inputting the second information into the first prediction model, the first prediction model will input the water demand required by the first region.

[0033] In this embodiment, the establishment of the first prediction model can be divided into the following steps: 1. Data requirement definition: Determine the information to be collected, such as the amount of water required for fire extinguishing after a fire occurs. 2. Data collection and preprocessing: Collect the required data, such as collecting the amount of water required for fire extinguishing through historical fire cases, and then preprocess the collected information to obtain the correspondence between the actual fire situation and the amount of water required for fire extinguishing. 3. Model selection: Select a model that can correspond the actual fire situation and the amount of water required for fire extinguishing. 4. Model training: Input the collected data into the selected model and adjust the model based on the input results. 5. Model validation and evaluation: Validate the model by inputting the data on the amount of water required for fire extinguishing collected from historical fire cases and the actual fire data into the adjusted model, and validate the model based on the input and output results.

[0034] The establishment and application of the first model emphasizes the combination of theory and practice. Through continuous iteration and optimization, it ensures that the fire sprinkler prediction model can adapt to complex and ever-changing fire situations and effectively guide actual firefighting actions based on the actual fire situation (second information).

[0035] In one embodiment of this disclosure, the control method for the sprinkler system includes: In response to the demand for water being less than the target water storage capacity, the sprinkler module is controlled to spray water to all first priority first areas with a first water output for fire extinguishing, and the sprinkler module is controlled to spray water to all second priority second areas with a second water output for fire extinguishing; wherein, the target water storage capacity is the water storage capacity of the sprinkler module, and the first water output is greater than the second water output.

[0036] If the first information of the first region is input into the first prediction model, the first prediction model will output the water consumption information of the first region.

[0037] In this embodiment, the intelligent control logic of the sprinkler system fully considers the matching of water distribution with fire priority to achieve efficient and rational utilization of fire extinguishing resources.

[0038] One specific step can be as follows: First, the system assesses the total water demand (required water volume) based on the current fire situation. This total demand includes the water requirements for all first and second priority zones, as well as the target water volume (referencing the water storage capacity of the sprinkler modules). Second, a fire suppression strategy is formulated based on priority: First priority zone fire suppression: When the system determines that the required water volume is less than the water storage capacity of the sprinkler modules (i.e., the target water volume is sufficient), priority is given to suppressing fires in the first priority zones. All first priority zones (fire zones with personnel) will receive sufficient water support, and the sprinkler modules will spray water at the highest possible flow rate. The high initial flow rate aims to quickly control the fire and prioritize personnel safety. Second priority zone fire suppression: While ensuring sufficient water for fire suppression in the first priority zones, the system also has the capacity to supply water for fire suppression in the second priority zones (fire zones without personnel). These areas will be sprayed with water at a second flow rate, which is lower than the first flow rate. This ensures that even with limited resources, these areas can be effectively extinguished, preventing the fire from spreading and protecting property and the environment.

[0039] This embodiment achieves efficient firefighting operations while ensuring personnel safety, and makes the most of limited water resources, demonstrating intelligent and human-centered design in fire emergency response.

[0040] In one embodiment of this disclosure, the control method for the sprinkler system includes: In response to the demand water volume being greater than or equal to the target water storage volume, a first demand water volume and a second demand water volume are determined. The first demand water volume is the demand water volume for fire suppression in the first area of ​​all first priority, and the second demand water volume is the demand water volume for fire suppression in the first area of ​​all second priority. The target water storage volume is the water storage volume of the sprinkler module. In response to the first water demand being less than the water demand, and the second water demand being greater than the difference in water volume, the sprinkler module is controlled to spray water to all first priority first areas with a first water output for fire extinguishing, and the sprinkler module is controlled to spray water to all second priority second areas with a third water output for fire extinguishing; the difference in water volume is the difference between the water demand and the first water demand, and the third water output is determined based on the difference in water volume.

[0041] The system calculates the water required for firefighting in all first-priority areas (fire zones with personnel) as the first-priority water requirement, which is the absolute priority to meet. The water required for firefighting in all second-priority areas (fire zones without personnel) is the second-priority water requirement.

[0042] In this embodiment, when faced with an emergency where the required water volume is greater than or equal to the target water storage volume, the system adopts a more refined water allocation strategy to ensure that, with limited water resources, personnel safety is prioritized while controlling the spread of fire as much as possible.

[0043] A specific operating procedure can be as follows: 1. Demand Water Volume and Target Storage Capacity Assessment: When the system identifies that the total water volume required for fire suppression (demand water volume) is equal to or exceeds the water volume stored in the sprinkler module (target water volume), this indicates that water resources are extremely scarce and precise water allocation is necessary. 2. Priority Demand Water Volume Division: First demand water volume, second demand water volume. 3. Water Volume Allocation Strategy: Prioritizing First Priority Areas: If the first demand water volume is less than the total demand water volume, it means that there is still water remaining after satisfying the fire suppression needs of the first priority area. The difference water volume is then calculated: the difference water volume is the total demand water volume minus the first demand water volume. This portion of water will be used for fire suppression in the second priority area. Fire Suppression in Second Priority Areas: The system will determine the third water volume to be delivered to the second priority area based on the difference water volume. This means that although the water demand of the second priority area cannot be fully met, fire suppression operations will be carried out as much as possible based on the remaining water volume. The third water volume is the result of reasonable allocation based on the difference water volume.

[0044] The system calculates the first priority water demand for firefighting in all first priority areas (fire zones with personnel), which is the water demand that must be met first. The second priority water demand is calculated for firefighting in all second priority areas (fire zones without personnel).

[0045] In this embodiment, when faced with an emergency where the required water volume is greater than or equal to the target water storage volume, the system adopts a more refined water allocation strategy to ensure that, with limited water resources, personnel safety is prioritized while controlling the spread of fire as much as possible.

[0046] In this embodiment, the sprinkler module will first spray water at a first-priority flow rate to extinguish the fire in all first-priority areas, ensuring maximum protection of personnel safety. Simultaneously, it will spray water at a calculated third-priority flow rate to extinguish the fire in second-priority areas, striving to control the fire and minimize losses with limited resources. This strategy ensures optimal allocation of firefighting resources and balances personnel safety with property protection in situations of extreme water scarcity.

[0047] In one embodiment of this disclosure, the control method for the sprinkler system includes: Based on the smoke concentration information and the temperature information, it is determined whether the target area contains a first region.

[0048] Smoke concentration information in the parking lot area can be obtained through a smoke sensor pre-set in the target area, and temperature information can be obtained through a temperature sensor in the target area.

[0049] In this embodiment, the control method of the sprinkler system includes: determining whether a first area exists in the target area based on smoke concentration information and temperature information.

[0050] The specific implementation steps of this embodiment may include the following aspects: 1. Data acquisition: First, smoke concentration and temperature changes in the environment are continuously monitored by smoke sensors and temperature sensors installed in the target area. These smoke sensors and temperature sensors can be distributed, covering various locations in the target area to ensure the comprehensiveness and accuracy of the data. 2. Data analysis: The collected smoke concentration and temperature information is transmitted to the central control system or data processing unit in real time. The system analyzes the smoke concentration and temperature information through algorithms to identify areas where a fire has occurred or is about to occur. 3. Threshold setting: Thresholds for smoke concentration and temperature are preset. When the readings of any one or both exceed these thresholds, the area can be considered as an area where a fire has occurred or is about to occur.

[0051] By analyzing smoke concentration and temperature information, it is possible to determine whether a fire has occurred in the target area. Through multiple functions, the target area can be monitored, increasing the ability to identify fires.

[0053] In one embodiment of this disclosure, the computing unit 22 is specifically used for: The fire type of each first area is determined based on the second information corresponding to each first area.

In response to the fire type being classified as the first fire type in the first zone, the fire suppression priority for the first zone is set to the highest priority.
