Description

Technical Field

[0001] This application relates to the field of fire water supply technology, specifically to a fire water supply system control method, device, storage medium, and electronic equipment. Background Technology

[0002] A fire-fighting water supply system is a water supply system used for fire suppression. It provides a water source during a fire to ensure the normal operation of fire-fighting equipment and the smooth progress of firefighting efforts. A fire-fighting water supply system typically includes a fire pipe network, a fire water tank, fire pumps, and fire hoses. Normally, the fire pumps start when the pressure in the fire pipe network is low, pumping water from the fire water tank into the fire pipe network on each floor. This increases the pressure in the fire pipe network to a certain value, allowing the fire hoses to have better impact force and efficiency when a fire occurs, ensuring the final fire suppression effect.

[0003] Currently, the fire water supply system is mainly controlled automatically through a control cabinet. Personnel pre-set the reasonable pressure range of the fire pipeline network. When the pressure in the fire pipeline network is lower than the lower limit of the reasonable pressure range, the fire pump is automatically started to pressurize the fire pipeline network and stabilize the pressure in the fire pipeline network within the reasonable pressure range. If a fire occurs at a location that is far from the fire hose and exceeds the coverage range of the fire hose under the current pressure in the fire pipeline network, i.e., a fire in a fire blind spot, it will be impossible to respond to the fire in the fire blind spot in a timely manner. Summary of the Invention

[0004] In order to respond promptly to fire extinguishing blind spots in the event of a fire, this application provides a fire water supply system control method, device, storage medium and electronic equipment.

[0005] The first aspect of this application provides a method for controlling a fire-fighting water supply system, specifically including:

[0006] Obtain the first pressure value of the fire protection pipe network on the floor;

[0007] When the first pressure value is within the standard pressure range, the maximum range of the target fire hose in the floor is determined based on the first pressure value. The maximum range is the range of the target fire hose after the corresponding fire hose is fully deployed.

[0008] Based on the maximum range, determine the coverage area of ​​the target fire hose, and based on the coverage area, determine whether there are fire blind spots on the floor.

[0009] If there is a fire blind area, a target fire water pump corresponding to the target fire monitor is started, and the outlet pressure of the target fire water pump is increased according to a target distance between the fire blind area and a target coverage area, so that the target fire monitor can cover the fire blind area, and the target coverage area is a sub-area in the coverage area that is closest to the fire blind area.

[0010] By adopting the technical solution, the maximum range of the target fire monitor at the first pressure value is determined, and based on the fact that the corresponding fire hose is fully deployed, the coverage area of the target fire monitor for fire extinguishing can be further determined, and the target fire monitor can extinguish fire at positions in the coverage area. Further, it is determined whether there is a fire blind area outside the coverage area, that is, an area that cannot be covered by the target fire monitor at the first pressure value. If there is a fire blind area, the outlet pressure of the target fire water pump is increased according to the target distance between the fire blind area and the closest target coverage area, the fire pipe network is pressurized, and the range of the target fire monitor is further improved, so that the target fire monitor can cover the fire blind area. Once a fire occurs in the fire blind area, the fire blind area can be promptly extinguished.

[0011] Optionally, the determination of the coverage area of the target fire monitor based on the maximum range specifically includes:

[0012] The sum of the maximum range and the maximum radiation length of the target fire monitor is calculated to obtain a fire coverage length, and the maximum radiation length is the sum of the length of the target fire monitor and the length of the corresponding fire hose.

[0013] The laying trajectories of the at least one fire hose in the floor are simulated by a preset complex trajectory model, the length of each laying trajectory is the fire coverage length, and the starting point of each laying trajectory is the position of the target fire monitor.

[0014] The endpoints of each laying trajectory are connected to obtain the coverage area of the target fire monitor.

[0015] By adopting the technical solution, the maximum range and the maximum radiation length are summed to obtain the fire coverage length, that is, the farthest distance that can be covered by the target fire monitor. Then, different laying trajectories with the fire coverage length are simulated by the complex trajectory model, and finally, the coverage area of the target fire monitor is determined according to the connection of the endpoints of each laying trajectory, so that the maximum coverage range of the target fire monitor is accurately determined, and the subsequent determination of the fire blind area is facilitated.

[0016] Optionally, the determination of whether there is a fire blind area in the floor based on the coverage area specifically includes:

[0017] statistically count an area of a remaining area in the floor except the coverage area, and compare the area with an area threshold value;

[0018] If the area is greater than the area threshold value, a combustible material appearance frequency in the corresponding remaining area is determined within a preset time before a current time.

[0019] When the combustible material appearance frequency exceeds a frequency threshold value, an interval duration from appearance to disappearance of the combustible material each time is counted.

[0020] A ratio of a number of interval durations exceeding a duration threshold value to the combustible material appearance frequency is calculated, and if the ratio exceeds a ratio threshold value, it is determined that a fire-fighting blind area exists, and the corresponding remaining area is determined as the fire-fighting blind area.

[0021] By using the above technical solution, the area of the remaining area being greater than the area threshold value indicates that there is a fire hazard. Further, if the combustible material appearance frequency in the remaining area exceeds the frequency threshold value, it indicates that the remaining area often piles combustible materials. Then, if the ratio exceeds the ratio threshold value, it indicates that the remaining area not only often piles combustible materials, but also the combustible materials are not cleaned in time, resulting in a relatively high risk of fire in the remaining area. Finally, the remaining area is determined as the fire-fighting blind area, so that the area in which the target fire-fighting monitor lance cannot cover the fire risk is accurately determined.

[0022] Optionally, according to the target distance between the fire-fighting blind area and the target coverage area, the outlet pressure of the target fire-fighting water pump is increased, and the method further comprises:

[0023] When the increased outlet pressure does not reach a pressure upper limit value, a second pressure value of a fire-fighting pipe network corresponding to the target fire-fighting monitor lance is obtained.

[0024] If the second pressure value is not in the standard pressure range, a third pressure value is obtained by reducing the second pressure value through a water pressure regulator until the third pressure value is in the standard pressure range.

[0025] It is determined whether a fire-fighting monitor lance of an adjacent floor can cover the fire-fighting blind area, and if the fire-fighting monitor lance of the adjacent floor can cover the fire-fighting blind area, the third pressure value is maintained unchanged.

[0026] If not, a reminder information is sent to a terminal of a person, so that the person regularly checks the fire-fighting blind area.

[0027] By adopting the technical scheme, the increased outlet pressure does not reach the pressure upper limit value, indicating that the outlet pressure of the current target fire pump is reasonable. Further, if the second pressure value of the fire pipe network corresponding to the target fire gun at this time is not in the standard pressure range, it indicates that the second pressure value is large, and the fire pipe network is prone to damage due to excessive pressure. If the second pressure value is reduced to the third pressure value, the target fire gun will not be able to cover the fire blind area. Then, if the fire gun of the adjacent floor can cover the fire blind area, the pressure in the fire pipe network corresponding to this floor can remain unchanged. Otherwise, if a fire occurs in the fire blind area, it will not be able to respond in time, so the personnel periodically check the fire blind area to reduce the possibility of fire in the fire blind area.

[0028] Optionally, if the fire gun of the adjacent floor can cover the fire blind area, after maintaining the third pressure value unchanged, the method further comprises:

[0029] determining the fire pump corresponding to the fire gun of the adjacent floor and the target fire pump corresponding to the target fire gun as an associated pump combination;

[0030] after the inspection period, determining whether the inspection fire pump currently in the inspected state is any one of the fire pumps in the associated pump combination, and if so, determining the remaining fire pumps in the associated pump combination as the next inspection object;

[0031] when the inspection result of the inspection fire pump is that there is no fault, shortening the preset two-pump inspection interval and increasing the inspection time of the next inspection object.

[0032] By adopting the technical scheme, if the inspection fire pump currently being inspected is any one of the fire pumps in the associated pump combination, the remaining fire pumps are determined as the next inspection object, so that it can be determined in time whether the fire blind area can be handled in response to a fire. Then, when the inspection fire pump has no fault, the two-pump inspection interval is shortened, so that the fault condition of the next inspection object can be known as soon as possible, and the inspection time of the next inspection object is increased to ensure the accuracy of the inspection result, so that it can be known in time whether the fire blind area and the non-fire blind area of the floor can be handled in response to a fire.

[0033] Optionally, before determining whether the inspection fire pump currently in the inspected state is any one of the fire pumps in the associated pump combination after the inspection period, the method further comprises:

[0034] counting the number of floors having fire blind areas;

[0035] if the number of floors exceeds a number threshold, reducing the preset initial inspection period of the fire pump to obtain the inspection period.

[0036] By adopting the above technical solution, if the number of floors exceeds the threshold, it indicates that there are fire blind spots on many floors, which in turn indicates that the pressure demand in the fire pipeline network is large. Therefore, by reducing the initial inspection cycle of the fire pumps and increasing the frequency of troubleshooting all fire pumps, it can be ensured that the fire pumps on each floor can be used normally.

[0037] Optionally, the IoT control cabinet includes a main controller and a redundant controller, and the method further includes:

[0038] When it is necessary to start or stop the target fire pump, the redundant controller detects whether the main controller has stopped working.

[0039] If so, the target fire pump is started or stopped by the redundant controller.

[0040] By adopting the above technical solution, if the main controller fails and stops working, the system switches to the redundant controller to control the start or stop of the target fire pump, thereby enabling the IoT control cabinet to continue to control the fire water supply system and respond to fires in a timely manner.

[0041] A second aspect of this application provides a fire-fighting water supply system control device, specifically comprising:

[0042] The pressure acquisition module is used to acquire the first pressure value of the fire protection pipe network on each floor.

[0043] The range determination module is used to determine the maximum range of the target fire hose in the floor based on the first pressure value when the first pressure value is within the standard pressure range. The maximum range is the range of the target fire hose after the corresponding fire hose is fully deployed.

[0044] The area determination module is used to determine the coverage area of ​​the target fire hose based on the maximum range, and to determine whether there are fire blind spots in the floor based on the coverage area.

[0045] The pressure adjustment module is used to activate the target fire pump corresponding to the target fire hose if a fire blind zone exists, and increase the outlet pressure of the target fire pump according to the target distance between the fire blind zone and the target coverage area, so that the target fire hose can cover the fire blind zone. The target coverage area is the sub-area in the coverage area with the smallest distance from the fire blind zone.

[0046] By adopting the technical scheme, after the pressure acquisition module acquires the first pressure value, when the first pressure value is in the standard pressure range, the range determination module determines the maximum range of the target fire water gun. Then, the range determination module determines the coverage area according to the maximum range, and judges whether there is a fire blind area in the floor. If there is, the outlet pressure of the target fire water gun is increased according to the target distance, so as to increase the first pressure value, so as to increase the range of the target fire water gun, and finally the target fire water gun can cover the fire blind area.

[0047] In a third aspect of the present application, a computer readable storage medium is provided, and the computer readable storage medium stores a computer program. When the computer program is loaded and executed by a processor, the method steps of any one of the first aspect are executed.

[0048] In a fourth aspect of the present application, an electronic device is provided, specifically comprising:

[0049] The processor, the memory, and the computer program stored in the memory and capable of running on the processor, the processor is used to load and execute the computer program stored in the memory, so that the electronic device executes the method of any one of the first aspect.

[0050] In summary, the present application includes at least one of the following beneficial technical effects:

[0051] After determining the maximum range of the target fire water gun at the first pressure value, and based on the corresponding fire hose being fully deployed, the coverage area of the target fire water gun for extinguishing fire can be further determined, and the target fire water gun can extinguish fire at positions in the coverage area. Further, it is judged whether there is a fire blind area outside the coverage area, that is, the area that the target fire water gun cannot cover at the first pressure value. If there is a fire blind area, the outlet pressure of the target fire water pump is increased according to the target distance from the fire blind area to the nearest target coverage area, the fire pipe network is pressurized, and the range of the target fire water gun is further improved, so that the target fire water gun can cover the fire blind area. Once a fire occurs in the fire blind area, the fire blind area can be promptly extinguished. BRIEF DESCRIPTION OF DRAWINGS

[0060] Referring to Figure 1 The embodiments of the present application disclose a flowchart of a fire water supply system control method, which can be implemented by relying on a computer program, and can also be run on a fire water supply system control device based on the von Neumann system. The computer program can be integrated in an application, or can be run as an independent tool class application. Specifically, the computer program comprises:

[0061] S101: Obtain a first pressure value of a fire pipe network of a floor.

[0062] Specifically, the first pressure value of the fire pipe network actually refers to a water pressure value in the fire pipe network. The fire pipe network is an important component of a fire water supply system, which refers to a pipe system for fire prevention and fire extinguishing, used to connect fire equipment such as fire water guns, and transport water, gas or other media for fire extinguishing. It is usually a network composed of multiple pipes. The water in the fire pipe network is pumped from a fire water tank by a fire pump, wherein the fire water tank is a man-made water storage facility for fixed or mobile fire pump water suction. The fire pump is used to transport water from the water source to the fire facility. Therefore, in the embodiment of the present application, the Internet of Things control cabinet can obtain the first pressure value of the fire pipe network of the floor through the pressure sensor arranged on the outlet pipe of the fire pump. It should be noted that the Internet of Things control cabinet is an execution subject of a fire water supply system control method provided in the embodiment of the present application. The Internet of Things control cabinet refers to an intelligent device integrated with Internet of Things technology, which has the functions of controlling the fire pump, monitoring the pressure and temperature of the fire pipe network, and can be remotely monitored and operated, thereby improving the safety and reliability of the fire system.

[0063] S102: When the first pressure value is in a standard pressure range, determining a maximum range of a target fire water gun in the floor according to the first pressure value.

[0064] Specifically, the standard pressure range is a reasonable pressure interval in the fire pipe network set in advance by personnel. If the pressure in the fire pipe network is too small, the fire water pressure will be small when a fire occurs, which will affect the radiation distance of the fire water gun and the fire extinguishing effect. If the pressure in the fire pipe network is too large, there is a risk of pipe rupture and damage. Further, if the first pressure value is in the standard pressure range, the maximum range of the target fire water gun in the floor is determined, wherein the maximum range refers to the range of the target fire water gun after the corresponding fire hose is fully deployed. The fire hose is connected to the target fire water gun and refers to a flexible pipe for conveying high-pressure water. A feasible way to determine the maximum range is to match the combination of the first pressure value and the fire hose length to the corresponding range through a range matching table. The range matching table includes combinations of the pressure in the fire pipe network, the length of the fire hose, and the corresponding range, because the greater the pressure in the fire pipe network, the greater the range of the target fire water gun; the greater the length of the fire hose, the smaller the range of the target fire water gun after the fire hose is fully deployed.

[0065] S103: Determine the coverage area of the target fire water gun according to the maximum range, and judge whether there is a fire blind area in the floor based on the coverage area.

[0066] Specifically, the coverage area is a range of areas that can be involved in fire extinguishing by the target fire monitor. After the maximum range of the target fire monitor is determined, a feasible way to determine the coverage area of the target fire monitor is to calculate the sum of the maximum range and the maximum radiation length of the target fire monitor to obtain the fire coverage length, and the maximum radiation length is the sum of the length of the target fire monitor and the length of the corresponding fire hose.

[0067] By means of the preset complex trajectory model, the laying trajectories of at least one fire hose in the floor are simulated, the length of each laying trajectory is the fire coverage length, and the starting point of each laying trajectory is the position of the target fire monitor;

[0068] The endpoints of the laying trajectories are connected to obtain the coverage area of the target fire monitor.

[0069] Specifically, the length of the target fire monitor and the length of the corresponding fire hose are summed to obtain the maximum radiation length, i.e., the farthest distance that the target fire monitor can be moved to, and then the maximum range and the maximum radiation length of the target fire monitor are summed to obtain the fire coverage length, wherein the length of the target fire monitor and the length of the fire hose are both preset information.

[0070] Further, the plan of the floor and the fire coverage length are input as input parameters into the preset complex trajectory model, wherein the complex trajectory model is used to simulate different trajectory routes, and in the embodiments of the present application, the complex trajectory model is used to simulate the laying trajectories of different fire hoses with a fixed length of the fire coverage length, the starting point of each laying trajectory is the position of the target fire monitor, and all the laying trajectories cover each movable area in the floor, such as a corridor, a stairwell, etc. In other embodiments, different laying trajectories can also be simulated by means of a random walk model or a particle swarm optimization model. Finally, the endpoints of each different laying trajectory are connected, and the closed area surrounded after the connection is determined as the coverage area of the target fire monitor.

[0071] Further, it is necessary to determine whether there is a fire blind area in the floor according to the coverage area, wherein the fire blind area refers to an area that cannot be covered by the target fire monitor when a fire hazard occurs. A feasible determination method is as follows:

[0072] The area of the remaining area in the floor except the coverage area is counted, and the area is compared with an area threshold value;

[0073] If the area is greater than the area threshold value, the frequency of combustible materials in the corresponding remaining area within a preset time before the current time is determined;

[0074] When the frequency of combustible materials exceeds a frequency threshold value, the interval duration from the appearance to the disappearance of each combustible material is counted;

[0075] The ratio of the number of interval durations exceeding the duration threshold to the combustible frequency is calculated, and if the ratio exceeds the ratio threshold, it is determined that there is a fire-fighting blind area, and the corresponding residual area is determined as the fire-fighting blind area.

[0076] Specifically, the area in the floor plan in the movable area excluding each coverage area is determined as the residual area. The planar area of each residual area in the floor plan is calculated by the preset matplotlib library, and then the area of each residual area is determined according to the drawing scale of the floor plan. Further, the area of each residual area is compared with the area threshold. If the area is not greater than the area threshold, it means that the corresponding residual area is small, and the density and quantity of combustibles and fire sources are relatively small, and the fire risk is small. If the area is greater than the area threshold, it means that the fire risk of the corresponding residual area is large, and then the monitoring video of the corresponding residual area in the preset time before the current time is retrieved through the camera, and the combustible frequency is counted according to the monitoring video. The combustible recognition model is mainly used to recognize the combustibles in the monitoring video. The combustible recognition model is a trained BP neural network model or a convolutional neural network model. The preset time is 7 days. In other embodiments, the preset time can also be 10 days.

[0077] Further, if the combustible frequency exceeds the frequency threshold, it means that the number of times that combustibles are placed by personnel in this residual area is relatively frequent, and the risk of fire occurring here is large. Then, the interval duration from the appearance to the disappearance of each combustible, i.e., the interval duration of the combustible being cleaned by personnel, is counted, and each interval duration is compared with the duration threshold. If the interval duration exceeds the duration threshold, it means that the combustible has not been processed in time. Further, if the ratio of the number of interval durations exceeding the duration threshold to the combustible frequency exceeds the ratio threshold, it means that the combustible in this residual area often appears to be not processed in time, and the risk of fire occurring is high. Then, it is determined that there is a fire-fighting blind area in this floor, and the residual area is determined as the fire-fighting blind area.

[0078] S104: If there is a fire-fighting blind area, the target fire water pump corresponding to the target fire water gun is started, and the outlet pressure of the target fire water pump is increased according to the target distance between the fire-fighting blind area and the target coverage area, so that the target fire water gun can cover the fire-fighting blind area.

[0079] Specifically, if it is determined that there is a fire blind area in the floor, and under the premise that the pressure in the current fire pipe network is a first pressure value, the target fire water gun in the floor cannot cover the fire blind area, resulting in that the target fire water gun cannot respond in time to fire extinguishing when a fire occurs in the fire blind area in the floor, the target fire water pump corresponding to the target fire water gun is started, that is, the fire water pump connected to the fire hydrant where the target fire water gun is located through the fire pipe network, so as to pressurize the fire pipe network.

[0080] Further, a target distance between the fire blind area and a target coverage area is calculated, wherein the target coverage area is a sub-area in the coverage area with the smallest distance from the fire blind area. A feasible target distance calculation method is to calculate the target distance between the fire blind area and the target coverage area by using a Euclidean distance function. Finally, according to a pressure adjustment matching table, an outlet pressure increase corresponding to the target distance is matched, the larger the target distance is, the greater the range that the target fire water gun needs to increase is, and the greater the outlet pressure increase of the target fire water pump is, so as to increase the pressure in the fire pipe network. The pressure adjustment matching table includes different target distances and corresponding outlet pressure increases. Further, the outlet pressure of the target fire water pump is increased according to the corresponding outlet pressure increase, so that the target fire water gun can cover the fire blind area, and the target fire water gun can respond in time to fire extinguishing when a fire occurs in the fire blind area. It should be noted that the outlet pressure refers to the water pressure value output by the target fire water pump at the outlet of the water pump.

[0081] In other embodiments, in addition to the main controller, the Internet of Things control cabinet is also provided with a redundant controller, wherein the main controller plays a core role in the Internet of Things control cabinet and can realize monitoring and remote control of the fire water pump equipment. The redundant controller is a control strategy for improving system reliability, which can keep the system working normally when some elements fail by adding redundant elements and designing corresponding redundant control algorithms. It can be understood as a backup controller of the main controller and can monitor the working state of the main controller in real time. When the target fire water pump needs to be started or stopped, the redundant controller detects whether the main controller stops working. If the main controller stops working, the control right is switched to the redundant controller to control the start or stop of the target fire water pump in order to ensure that the Internet of Things control cabinet can control the target fire water pump.

[0082] Referring to Figure 2 The embodiment of the present application discloses another flowchart of a fire water supply system control method, which can be realized by a computer program and can also run on a fire water supply system control device based on the von Neumann system. The computer program can be integrated in an application or run as an independent tool application. Specifically, the computer program comprises:

[0083] S201: Obtain a first pressure value of a fire pipe network of a floor.

[0084] S202: When the first pressure value is in a standard pressure range, determine a maximum range of a target fire monitor in the floor according to the first pressure value.

[0085] S203: According to the maximum range, determine a coverage area of the target fire monitor, and judge whether there is a fire blind area in the floor based on the coverage area.

[0086] S204: If there is a fire blind area, start a target fire pump corresponding to the target fire monitor, and increase an outlet pressure of the target fire pump according to a target distance between the fire blind area and the target coverage area, so that the target fire monitor can cover the fire blind area.

[0087] Specifically, steps S101-S104 can be referred to, which will not be described here.

[0088] S205: When the increased outlet pressure does not reach a pressure upper limit value, obtain a second pressure value of the fire pipe network corresponding to the target fire monitor.

[0089] S206: If the second pressure value is not in the standard pressure range, reduce the second pressure value by a water pressure regulator to obtain a third pressure value until the third pressure value is in the standard pressure range.

[0090] Specifically, after the outlet pressure of the target fire pump is increased, the increased outlet pressure is obtained. If the increased outlet pressure does not reach the pressure upper limit value, it indicates that the outlet pressure of the current target fire pump is in a reasonable interval. Then, the pressure sensor is used to obtain the second pressure value of the fire pipe network corresponding to the target fire monitor at the current time, i.e., the second pressure value of the fire pipe network through which water is delivered to the target fire monitor.

[0091] Further, it is judged whether the second pressure value is in the standard pressure range. If not, it indicates that the increased outlet pressure of the target fire pump causes the pressure of the fire pipe network to be too large. Then, the preset water pressure regulator is started to reduce the pressure in the fire pipe network, i.e., to reduce the second pressure value to obtain the third pressure value until the third pressure value is in the standard pressure range, thereby avoiding damage to the fire pipe network due to excessive pressure.

[0092] S207: Determine whether a fire monitor of an adjacent floor can cover the fire blind area. If the fire monitor of the adjacent floor can cover the fire blind area, the third pressure value is maintained unchanged.

[0093] S208: If not, send a reminder information to a terminal of a person to make the person check the fire blind area regularly.

[0094] Specifically, after the fire pipe network corresponding to the target fire monitor on the floor returns to the standard pressure range, the adjacent pressure value of the fire pipe network corresponding to the fire monitor on the adjacent floor of the floor is obtained, and the fire coverage length corresponding to the fire monitor on the adjacent floor is determined according to the adjacent pressure value. For details, refer to steps S102 and S103, which will not be described here. Further, the trajectory length from the position of the fire monitor on the adjacent floor to the fire blind area is calculated. If the trajectory length is less than the fire coverage length corresponding to the fire monitor on the adjacent floor, it means that the fire monitor on the adjacent floor can cover the fire blind area under the adjacent pressure value. Therefore, the third pressure value can be maintained unchanged for the fire pipe network corresponding to the target fire monitor.

[0095] If the fire monitor on the adjacent floor cannot cover the fire blind area, it means that the target fire monitor cannot cover the fire blind area once a fire occurs in the fire blind area. If the corresponding fire pipe network pressure is too large and the fire monitor on the adjacent floor cannot cover in time, the terminal of the personnel is sent to remind the personnel to regularly patrol the fire blind area of the floor in order to improve the safety of the fire blind area. It should be noted that the terminal can be a smart phone or a personal computer (PC).

[0096] In other embodiments, after step S207, the fire pump corresponding to the fire monitor on the adjacent floor and the target fire pump corresponding to the target fire monitor are determined as the associated pump combination.

[0097] After the inspection period, it is determined whether the inspection fire pump currently in the inspection state is any one of the fire pumps in the associated pump combination. If so, the remaining fire pumps in the associated pump combination are determined as the next inspection object.

[0098] When the inspection result of the inspection fire pump is no fault, the pre-set two-pump inspection interval is shortened, and the inspection time of the next inspection object is increased.

[0099] Specifically, after determining that the fire water gun of the adjacent floor can cover the fire blind area, the fire water pump corresponding to the fire water gun of the adjacent floor and the target fire water pump of the floor are determined as the associated water pump combination. Since the Internet of Things control cabinet automatically and periodically performs fault inspection on each fire water pump, in the embodiment of the present application, the inspection is performed after every other inspection period, and the fire water pump is promptly checked for faults, so that each fire water pump can be normally started when necessary. Therefore, after the inspection period, it is determined whether the inspection fire water pump currently in the inspected state is any one of the fire water pumps in the associated water pump combination. A feasible determination method is to obtain the target model of the inspection fire water pump. If the target model is consistent with the model of any one of the fire water pumps in the associated water pump combination, it is determined that the inspection fire water pump is any one of the fire water pumps in the associated water pump combination.

[0100] Further, after determining that the inspection fire water pump is any one of the fire water pumps in the associated water pump combination, the remaining fire water pumps in the associated water pump combination are determined as the next inspection object. If the inspection result of the inspection fire water pump is that there is no fault, it means that the next inspection can continue. Otherwise, it needs to be handled in time, and after the fault is repaired, the next inspection will be performed. Further, if the inspection fire water pump is the target fire water pump, the preset two-pump inspection interval is shortened to inspect the next inspection object as soon as possible, so that it can be determined in time whether the fire water pump corresponding to the adjacent floor that can cover the fire blind area has a fault, and further determine whether the fire hazard of the fire blind area can be responded in time. If the fire water pump corresponding to the adjacent floor also fails, personnel need to be notified to perform fire risk inspection on the fire blind area. If the inspection fire water pump is the fire water pump corresponding to the adjacent floor that can cover the fire blind area, the preset two-pump inspection interval is shortened to determine whether the fire hazard of the non-fire blind area in the floor can be responded in time. In addition, the inspection time of the next inspection object needs to be increased to ensure the accuracy of the inspection result, so as to accurately know whether the fire blind area and the non-fire blind area of the floor can be responded in time in case of fire. The two-pump inspection interval refers to the time interval between the completion of the inspection of one fire water pump and the start of the inspection of the next fire water pump.

[0101] In another embodiment, when the second pressure value is within the standard pressure range, it means that the target fire water gun can cover the fire blind area under normal fire pipe network pressure. The target fire water pump and the fire water pump corresponding to the adjacent floor that can cover the fire blind area are determined as the associated water pump combination. When the inspection fire water pump is any one of the associated water pump combination, the remaining fire water pumps are determined as the next inspection object, and the two-pump inspection interval is shortened, so that after the inspection of the two is completed, once one of the fire water pumps in the associated water pump combination temporarily fails, it can be determined in time whether the fire in the fire blind area can be responded in time.

[0102] In yet another embodiment, before determining whether the fire-fighting water pump currently in the inspection state is any one of the fire-fighting water pumps in the associated water pump combination, the number of floors with fire-fighting blind areas is counted. If the number of floors exceeds the number threshold, it means that many floors have fire-fighting blind areas, and thus the pressure boosting demand in the fire-fighting pipe network is large. Then, the initial inspection period of the fire-fighting water pump is reduced to obtain the inspection period, and the troubleshooting frequency of all fire-fighting water pumps is increased to ensure that the fire-fighting water pumps of each floor can be normally used when in use.

[0103] The implementation principle of the fire-fighting water supply system control method of the embodiments of the present application is as follows: after determining the maximum range of the target fire-fighting water gun at the first pressure value, it can be further determined that the target fire-fighting water gun can extinguish fires at positions in the coverage area in response to the target fire-fighting water gun. Further, it is determined whether there is a fire-fighting blind area outside the coverage area, i.e., the area that the target fire-fighting water gun cannot cover at the first pressure value. If there is a fire-fighting blind area, the outlet pressure of the target fire-fighting water pump is increased according to the target distance from the fire-fighting blind area to the nearest target coverage area, the fire-fighting pipe network is boosted, and thus the range of the target fire-fighting water gun is improved, so that the target fire-fighting water gun can cover the fire-fighting blind area. Once a fire occurs in the fire-fighting blind area, the fire-fighting blind area can be promptly extinguished.
