Description

Technical Field

[0001] The invention relates to the technical field of fire hydrant water pressure adjustment, and in particular to a rapid rescue water supply system for residential fires. Background Art

[0002] The rescue problem in high-rise residential buildings in old communities when a fire occurs is a major problem in today's society. Since old residential communities have been built for a long time, there are many flammable materials and the internal environment is complex, it is very easy for fire trucks to be unable to arrive, firefighting equipment is lacking, or water sources are insufficient, which leads to the further spread of the fire, posing a great threat to life and economic losses to residents in the community. In order to ensure that when a fire occurs in a high-rise residential building, there is sufficient water to extinguish the fire as soon as possible, without waiting for large-scale pipe filling, and effectively reducing the time for firefighters to lay water hoses, the existing method usually chooses to expand the water supply system in the community, that is, to install a residential unit fire hydrant system, in which the top-floor fire hydrant of the high-rise residential building is connected to the top-floor tap water pipe in the residential unit fire hydrant system, so that the fire hydrants in the high-rise residential building have sufficient water pressure within 24 hours, ensuring the water supply efficiency and stability when a fire occurs. A simple diagram of the connection between the top-floor fire hydrant and the top-floor tap water pipe in the residential unit fire hydrant system is shown below. Figure 1 As shown by Figure 1 It can be seen that the pipeline connecting the top-floor fire hydrant and the top-floor water pipe includes copper ball valve 1, anti-pollution backflow prevention valve, mechanical water meter, vacuum breaker and copper ball valve 2 from the top-floor fire hydrant to the top-floor water pipe. Among them, copper ball valve 1 and copper ball valve 2 are used to control the opening and closing of the connection between the fire hydrant and the water pipe; the anti-pollution backflow prevention valve is used to prevent the water in the fire hydrant system from flowing back into the water pipe to ensure that the water for residents is clean; the mechanical water meter is used to detect the water pressure and water flow speed in the connecting pipe; the vacuum breaker is used to prevent the siphon phenomenon when the water pipe is cut off, so as to avoid sucking a small amount of water in the fire hydrant system into the water pipe.

[0003] In actual situations, if the water pressure of the top-floor fire hydrants is maintained for a long time, it is easy to cause fluctuations in the water pressure in residential buildings. At the same time, the loss of equipment and energy consumption are too large, which may cause problems with the fire-fighting equipment on the floors of residential buildings in the community, and there will be abnormal rescue water supply in the event of a fire. Summary of the invention

[0004] In order to solve the technical problem that the water pressure of the top-floor fire hydrant is maintained for a long time, resulting in abnormal rescue water supply when a fire occurs, the purpose of the present invention is to provide a residential fire rapid rescue water supply system, and the technical solution adopted is as follows:

[0005] An embodiment of the present invention provides a residential fire rapid rescue water supply system, the system comprising the following steps:

[0006] A data acquisition module is used to obtain, after a fire floor is detected, the water pressure of the fire hydrants on each floor between the fire floor and the top floor of the residential building where it is located at each moment, the water pressure of the water pipe on the top floor at each moment, the water flow velocity in the pipe connected to the fire hydrant on the top floor and the water pipe on the top floor at each moment, and the radius of the connected pipe;

[0007] The opening amplitude acquisition module of the copper ball valve 1 is used to acquire the opening amplitude of the copper ball valve 1 at each moment according to the water pressure of the fire hydrant on the fire floor at each moment, the height difference between the fire floor and the top floor, the water pressure change between the fire floor and the top floor at each moment, and the water pressure difference between the top floor water pipe and the top floor fire hydrant at each moment;

[0008] The opening amplitude acquisition module of the copper ball valve 2 is used to acquire the opening amplitude of the copper ball valve 2 at each moment according to the opening amplitude of the copper ball valve 1 at each moment, the water flow velocity at each moment and the degree of change of the water flow velocity, the radius of the connected pipe, the water pressure difference between the top-floor water pipe and the top-floor fire hydrant at each moment and the degree of change of the water pressure difference;

[0009] The stop module is used to stop adjusting the opening amplitudes of the copper ball valve 1 and the copper ball valve 2 until the opening amplitude of the copper ball valve 2 is larger than the opening amplitude of the copper ball valve 1.

[0010] Furthermore, the method for obtaining the opening amplitude of the copper ball valve 1 at each moment is:

[0011] For any moment after the fire floor is discovered, the water pressure demand of the fire hydrant on the fire floor at that moment is obtained according to the water pressure of the fire hydrant on the fire floor at that moment, the height difference between the fire floor and the top floor, and the change of water pressure between the fire floor and the top floor at that moment;

[0012] The water pressure difference between the top-floor water pipe and the top-floor fire hydrant at that moment is used as the water pressure compensation amplitude of the top-floor fire hydrant at that moment;

[0013] According to the water pressure demand and the water pressure compensation amplitude, the opening adjustment weight of the copper ball valve 1 at this moment is obtained;

[0014] The product of the maximum opening amplitude of the copper ball valve 1 and the opening adjustment weight is taken as the opening amplitude of the copper ball valve 1 at this moment.

[0015] Furthermore, the method for obtaining the water pressure demand is:

[0016] The difference between the preset minimum water pressure of the fire hydrant and the water pressure of the fire hydrant on the fire floor at that moment is used as the reference water pressure required to be increased for the fire hydrant on the fire floor at that moment;

[0017] For any two adjacent floors between the fire floor and the top floor, obtain the ratio of the water pressure difference between the two adjacent floors at that moment to their height difference, as the water pressure variation amplitude of the fire hydrants of the two adjacent floors at that moment;

[0018] The average of the water pressure variation amplitudes of the fire hydrants on all two adjacent floors between the fire floor and the top floor at that moment is taken as the overall water pressure variation amplitude between the fire floor and the top floor at that moment;

[0019] The product of the height difference between the fire floor and the top floor and the overall water pressure change amplitude is used as the required overall water pressure increase between the fire floor and the top floor at that moment;

[0020] The sum of the reference water pressure requirement and the overall water pressure requirement is taken as the water pressure requirement of the top-floor fire hydrant at that moment.

[0021] Furthermore, the calculation formula for the start-up adjustment weight is: In the formula, is the opening adjustment weight of copper ball valve 1 at the tth moment; N t is the water pressure demand of the top fire hydrant at the tth moment; ΔP t is the water pressure compensation amplitude of the top-floor fire hydrant at the tth moment; α is the first preset constant, which is greater than 0; norm is the normalization function.

[0022] Furthermore, the method for obtaining the opening amplitude of the copper ball valve 2 at each moment is:

[0023] At any time after the fire floor is discovered, the water inflow of the copper ball valve 1 at that time is obtained according to the opening amplitude of the copper ball valve 1 at that time, the water flow velocity at that time and the radius of the connected pipe;

[0024] According to the water inflow of copper ball valve 1 at this moment, the water pressure compensation amplitude of the top-level fire hydrant at this moment, and the opening amplitude of copper ball valve 1 at this moment, the reference opening amplitude of copper ball valve 2 at this moment is obtained;

[0025] According to the change degree of the water pressure compensation amplitude and the change degree of the water flow velocity at this moment, the opening correction weight of the copper ball valve 2 at this moment is obtained;

[0026] The reference opening amplitude of the copper ball valve 2 at this moment is corrected by the opening correction weight to obtain the opening amplitude of the copper ball valve 2 at this moment.

[0027] Furthermore, the calculation formula of the water inflow is: S t =v t ×(F1,t ×πR 2 );where S t is the water inflow of copper ball valve 1 at the tth moment; v t is the water flow velocity at the tth moment; F 1,t is the opening amplitude of the copper ball valve 1 at the tth moment; π is the pi; R is the radius of the connected pipe.

[0028] Furthermore, the method for obtaining the reference opening amplitude is:

[0029] According to the water inflow of the copper ball valve 1 at this moment and the water pressure compensation amplitude of the top fire hydrant at this moment, the reference adjustment weight at this moment is obtained; wherein the water inflow is positively correlated with the reference adjustment weight, and the water pressure compensation amplitude is negatively correlated with the reference adjustment weight;

[0030] The product of the opening amplitude of the copper ball valve 1 at this moment and the reference adjustment weight is used as the reference opening amplitude of the copper ball valve 2 at this moment.

[0031] Furthermore, the method for obtaining the start correction weight is:

[0032] Obtain the duration corresponding to the time interval between the moment and the previous adjacent moment as the first duration;

[0033] Obtaining the difference between the water pressure compensation amplitude at this moment and the previous adjacent moment as the first difference;

[0034] The ratio of the first difference to the first duration is used as the degree of change of the water pressure compensation amplitude at that moment;

[0035] Obtain the difference between the water flow velocity at this moment and the previous adjacent moment as the second difference;

[0036] The ratio of the second difference to the first duration is taken as the degree of change of the water flow velocity at that moment;

[0037] The product of the change degree of the water pressure compensation amplitude at this moment and the change degree of the water flow velocity at this moment is negatively correlated and normalized, and is used as the opening correction weight of the copper ball valve 2 at this moment.

[0038] Furthermore, the method for obtaining the opening amplitude of the copper ball valve 2 is:

[0039] The product of the opening correction weight of the copper ball valve 2 at this moment and the reference opening amplitude is used as the correction opening amplitude of the copper ball valve 2 at this moment;

[0040] The sum of the reference opening amplitude and the corrected opening amplitude of the copper ball valve 2 at this moment is taken as the opening amplitude of the copper ball valve 2 at this moment.

[0041] Furthermore, the fire floor is monitored by a fire alarm.

[0042] The present invention has the following beneficial effects:

[0043] The present invention monitors the water pressure of the fire hydrants of the entire residential building where the floor where the fire occurs in real time, and then determines the water pressure demand of the fire hydrants on the top floor in real time based on the water pressure change between the fire floor and the top floor, and the water pressure difference between the water pipe on the top floor and the fire hydrants on the top floor. Based on this, the opening amplitude of the copper ball valve 1 and the copper ball valve 2 in the pipe connecting the fire hydrant on the top floor and the water pipe on the top floor is adjusted in real time, and the water flow supply from the water pipe to the fire hydrant on the top floor is reasonably adjusted, thereby improving the water supply efficiency during the initial rapid fire extinguishing and avoiding damage to the fire hydrant pipe due to excessive water pressure of the fire hydrant, ensuring the stability of water supply during fire extinguishing, and facilitating efficient fire fighting on the fire floor.

[0050] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, features and effects of a residential fire rapid rescue water supply system proposed by the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0051] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0052] The specific scheme of the rapid rescue water supply system for residential fire provided by the present invention is described in detail below with reference to the accompanying drawings.

[0053] Embodiment 1:

[0054] The specific scenario of this embodiment is: when using a water gun to extinguish a fire, a higher water pressure is usually required to ensure the range and fire extinguishing effect of the fire extinguishing water gun. In the residential unit fire hydrant system, the fire hydrant pipes between each floor are connected, and as the floor height increases, the water pressure inside the fire hydrant is showing a decreasing trend. If the top floor fire hydrant is always connected to the civilian water pipe and the fire hydrant is kept at a high water pressure, it may affect the water pressure of the civilian water pipe, especially the excessive water pressure in the lower floors of the residential building will make the use of water pipes and faucets unstable. Therefore, in the absence of a fire, the water pressure inside the fire hydrant is usually maintained at a low level, and the top floor fire hydrant does not need to be connected to the civilian water pipe. When a fire floor occurs, the top floor fire hydrant is connected to the civilian water pipe, but if the water pressure inside the fire hydrant is controlled to rise rapidly, it is very likely that the water pipe pressure of the fire hydrant is too high and damaged, and then the target water pressure cannot be quickly reached, causing delays in rescue and causing more serious fire spread, and the overall reliability is low. Therefore, in order to stably and quickly increase the water pressure inside the fire hydrant and stably control the water pressure inside the fire hydrant, this embodiment analyzes the water pressure of the fire hydrant from the fire floor to the top floor, and then adjusts the opening amplitude of copper ball valve 1 and copper ball valve 2, so as to more accurately and reasonably control the water pressure inside the fire hydrant and ensure that the water supply of the fire hydrant remains stable during the fire fighting process on the fire floor.

[0055] The present invention proposes a rapid rescue water supply system for residential fires. Figure 2 , which shows a structural diagram of a residential fire rapid rescue water supply system provided by an embodiment of the present invention, the system includes: a data acquisition module 10, an opening amplitude acquisition module 20 of the copper ball valve 1, an opening amplitude acquisition module 30 of the copper ball valve 2 and a stop module 40.

[0056] The data acquisition module 10 is used to obtain the water pressure of the fire hydrants on each floor between the fire floor and the top floor of the residential building where it is located at each moment, the water pressure of the water pipe on the top floor at each moment, the water flow velocity in the pipe connecting the fire hydrant on the top floor and the water pipe on the top floor at each moment, and the radius of the connected pipe after a fire floor is monitored.

[0057] Specifically, in order to quickly find the fire floor, in the existing method, a fire alarm is installed on each floor of the residential building, and all the fire alarms are connected to the property monitoring system in the community. When a fire alarm sounds an alarm, the fire floor can be accurately determined by the property monitoring system. For the sake of clear explanation, this embodiment takes a fire floor as an example for analysis. When there is no fire, the fire hydrant is not connected to the civil water pipe, and the water pressure inside the fire hydrant is relatively small to reduce the loss of the fire hydrant equipment. When a fire floor is monitored, in order to quickly and stably extinguish the fire on the fire floor, it is necessary to increase the water pressure inside the fire hydrant. It is known that the fire hydrant pipes in the entire residential building are connected, and then the top fire hydrant can be connected to the civil water pipe, and the water in the water pipe is injected into the fire hydrant pipe to increase the water pressure inside the fire hydrant. In this embodiment, the top fire hydrant is connected to the water pipe through copper ball valve 1 and copper ball valve 2. It is known that if the water pressure inside the fire hydrant increases rapidly, it is very likely that the water pipe pressure of the fire hydrant will be too high and damaged, and then the target water pressure, i.e. the water pressure required by the fire extinguishing water gun, cannot be quickly reached. At the same time, the stability of the water pressure of the fire hydrant cannot be guaranteed, causing delays in rescue and causing more serious fire spread. Therefore, it is necessary to control the opening amplitude of the copper ball valve 1 and the copper ball valve 2, and reasonably control the water pressure of the fire hydrant, so as to avoid damage to the water pipe of the fire hydrant while quickly increasing the water pressure of the fire hydrant.

[0058] In this embodiment, the opening amplitude of copper ball valve 1 and copper ball valve 2 can be intelligently adjusted through the property monitoring system. In order to reasonably control the opening amplitude of copper ball valve 1 and copper ball valve 2, so that the water pressure inside the fire hydrant can stably and quickly reach the water pressure required by the fire extinguishing water gun, this embodiment installs a 1.6MPa pressure gauge on the fire hydrant pipe on each floor of the residential building. The 1.6MPa pressure gauge is used to obtain the water pressure of the fire hydrant on each floor between the fire floor and the top floor of the residential building where it is located at each moment (the floors between the fire floor and the top floor of the residential building where it is located include the fire floor and the top floor); and a water pressure gauge is also installed on the top floor water pipe to obtain the water pressure of the top floor water pipe at each moment; the water flow velocity at each moment in the pipe connected to the top floor fire hydrant and the top floor water pipe is obtained through a mechanical water meter; and the radius of the pipe connected to the top floor fire hydrant and the top floor water pipe is obtained at the same time. It should be noted that all the above-mentioned data can be directly uploaded to the property monitoring system. In this embodiment, the time interval between two adjacent moments of collecting data is set to 5 seconds. The implementer can set the time interval between two adjacent moments of collecting data according to actual conditions, which is not limited here.

[0059] It should be noted that during the process of connecting the fire hydrant on the top floor to the water pipe, the water pipe will not automatically stop supplying water. It is known that the water pressure inside the fire hydrant gradually decreases as the floor increases. At low floors, the water pressure inside the fire hydrant may meet the water pressure required by the water gun in the event of a fire. At this time, the water pressure inside the fire hydrant is not adjusted. This embodiment is mainly for high floors, where the internal water pressure of the fire hydrant on the high floors is lower than the preset minimum water pressure; this embodiment sets the preset minimum water pressure to 0.3MPa, and the implementer can set the size of the preset minimum water pressure according to actual conditions, which is not limited here. Therefore, the water pressure of the fire hydrant on the fire floor in this embodiment must be less than 0.3MPa.

[0060] It is known that copper ball valves 1 and 2 are respectively set on the pipes connecting the top-level fire hydrant and the top-level water pipe. By setting the opening range of copper ball valves 1 and 2, the water pressure inside the top-level fire hydrant can be quickly increased and the water pressure of the water pipe can be prevented from being too low, while preventing the fire hydrant pipe from being damaged by the sudden increase in water pressure inside the fire hydrant. By adjusting the opening range of copper ball valves 1 and 2, the water pressure rising trend inside the fire hydrant can present different states. When the opening amplitude of copper ball valve 1 is equal to the opening amplitude of copper ball valve 2, the civil water in the top-level water pipe flows smoothly into the top-level fire hydrant pipe through the pipe, that is, the water flow smoothly transitions between the top-level fire hydrant and the top-level water pipe; when the opening amplitude of copper ball valve 1 is larger than the opening amplitude of copper ball valve 2, since there is a water pressure difference between the top-level fire hydrant and the water pipe, the water inflow in the fire hydrant pipe is larger than the water outflow from the top-level water pipe, which can make the water pressure in the fire hydrant pipe increase faster; when the opening amplitude of copper ball valve 1 is smaller than the opening amplitude of copper ball valve 2, although there is a water pressure difference between the top-level fire hydrant and the water pipe, due to the smaller opening amplitude of copper ball valve 1, the water flow rate entering the fire hydrant system is smaller, and the water pressure inside the fire hydrant will increase more slowly. After the fire floor is discovered, in order to quickly extinguish the fire floor, it is necessary to quickly make the water pressure inside the fire hydrant reach the water pressure standard required by the fire extinguishing water gun. Therefore, in the early stage of extinguishing the fire floor, it is necessary to control the opening amplitude of copper ball valve 1 to be larger than the opening amplitude of copper ball valve 2, and then adjust the opening amplitude of copper ball valve 1 and copper ball valve 2 in real time as the water pressure inside the fire hydrant increases to avoid the internal water pressure of the fire hydrant rising too quickly and causing damage to the fire hydrant pipeline.

[0061] The opening amplitude acquisition module 20 of the copper ball valve 1 is used to obtain the opening amplitude of the copper ball valve 1 at each moment according to the water pressure of the fire hydrant on the fire floor at each moment, the height difference between the fire floor and the top floor, the water pressure change between the fire floor and the top floor at each moment, and the water pressure difference between the top floor water pipe and the top floor fire hydrant at each moment.

[0062] Specifically, when there is no fire floor, the internal water pressure of the fire hydrants on different floors decreases with the increase of the floor height due to the influence of gravity. In this embodiment, the water pressure inside the fire hydrants on the fire floor is adjusted by the top-floor fire hydrant connected to the water pipe to ensure that the water pressure of the fire hydrants on the fire floor meets the standard. Then, the embodiment first determines the internal water pressure demand of the top-floor fire hydrant at each moment by analyzing the water pressure of the fire hydrant on the fire floor at each moment, the height difference between the fire floor and the top floor, and the water pressure change between the fire floor and the top floor at each moment; the greater the internal water pressure demand of the top-floor fire hydrant at a certain moment, the larger the opening amplitude of the copper ball valve 1 should be at that moment, so as to increase the water pressure of the top-floor fire hydrant more quickly.

[0063] In order to analyze the opening amplitude of the copper ball valve 1 more accurately and in real time, and then analyze the water pressure difference between the top water pipe and the top fire hydrant at each moment, when the water pressure difference between the top water pipe and the top fire hydrant at a certain moment is smaller, it can be inferred that the water flow from the top water pipe to the top fire hydrant pipe at that moment is smaller, and the speed of water pressure increase in the fire hydrant pipe is slower. In order to increase the water pressure in the fire hydrant pipe, the opening amplitude of the copper ball valve 1 should be larger. Therefore, this embodiment obtains the opening amplitude of the copper ball valve 1 at each moment according to the water pressure of the fire hydrant on the fire floor at each moment, the height difference between the fire floor and the top floor, the water pressure change between the fire floor and the top floor at each moment, and the water pressure difference between the top water pipe and the top fire hydrant at each moment.

[0064] Preferably, in one possible implementation of this embodiment, the method for obtaining the opening amplitude of the copper ball valve 1 can be found in Figure 3 , which shows a flow chart of a method for obtaining the opening amplitude of a copper ball valve 1 provided in this embodiment, the method comprising the following steps:

[0065] Step S301: For any moment after the fire floor is discovered, the water pressure demand of the fire hydrant on the fire floor at that moment is obtained according to the water pressure of the fire hydrant on the fire floor at that moment, the height difference between the fire floor and the top floor, and the change in water pressure between the fire floor and the top floor at that moment.

[0066] The smaller the water pressure of the fire hydrant on the fire floor at this moment, the smaller the water pressure inside the fire hydrant on the fire floor, indicating that the water pressure of the fire hydrant on the fire floor needs to be increased, which indirectly indicates that the water pressure demand of the top fire hydrant at this moment is greater; at the same time, the water pressure change between the fire floor and the top floor at this moment is analyzed, that is, the degree of water pressure drop is analyzed. When the water pressure drop between the fire floor and the top floor at this moment is greater, and the height difference between the fire floor and the top floor is greater, in order to increase the water pressure of the fire hydrant on the fire floor, the water pressure demand of the top fire hydrant at this moment should be greater. Furthermore, this embodiment obtains the water pressure demand of the top fire hydrant at this moment according to the water pressure of the fire hydrant on the fire floor at this moment, the height difference between the fire floor and the top floor, and the water pressure change between the fire floor and the top floor at this moment.

[0067] Preferably, in an achievable manner of the present embodiment, the method for obtaining the water pressure demand is as follows: taking the difference between the preset minimum water pressure of the fire hydrant and the water pressure of the fire hydrant on the fire floor at that moment as the reference water pressure increase required for the fire hydrant on the fire floor at that moment; the larger the reference water pressure increase required, the smaller the water pressure of the fire hydrant on the fire floor at that moment, which indirectly indicates that the water pressure demand of the fire hydrant on the top floor at that moment should be larger; in order to more accurately analyze the water pressure demand of the fire hydrant on the top floor at that moment, and then for any two adjacent floors between the fire floor and the top floor, the ratio of the absolute value of the water pressure difference between the two adjacent floors at that moment and their height difference (the height difference between the ceilings of the two adjacent floors) is obtained as the water pressure change amplitude of the fire hydrants on the two adjacent floors at that moment; the larger the water pressure change amplitude, the greater the water pressure change of the fire hydrants between the two adjacent floors at that moment, in order to comprehensively analyze the water pressure change between the fire floor and the top floor at that moment, and then obtaining the water pressure change amplitude between the fire hydrants on the two adjacent floors at that moment The average of the water pressure variation amplitudes of all the fire hydrants on the two adjacent floors between the fire floor and the top floor is taken as the overall water pressure variation amplitude between the fire floor and the top floor at that moment; the larger the overall water pressure variation amplitude, the smaller the water pressure of the fire hydrant on the top floor at that moment, and in order to improve the stability and demand of the water pressure inside the fire hydrant, the water pressure demand of the fire hydrant on the top floor at that moment should be greater; at the same time, when the height difference between the fire floor and the top floor (the height difference between the ceiling of the fire floor and the ceiling of the top floor) is greater, in order to eliminate the influence of gravity on the water pressure of the fire hydrant, the water pressure demand of the fire hydrant on the top floor should be greater; therefore, the product of the height difference between the fire floor and the top floor and the overall water pressure variation amplitude is taken as the overall water pressure demand between the fire floor and the top floor at that moment; the larger the overall water pressure demand is, the greater the water pressure demand of the fire hydrant on the top floor at that moment should be, and then the sum of the reference water pressure demand and the overall water pressure demand is taken as the water pressure demand of the fire hydrant on the top floor at that moment.

[0068] It should be noted that when the fire floor is the top floor, the reference water pressure required to rise of the fire hydrants on the fire floor at that moment is directly used as the water pressure required of the fire hydrants on the top floor at that moment.

[0069] Step S302: The water pressure difference between the top-floor water pipe and the top-floor fire hydrant at that moment is used as the water pressure compensation amplitude of the top-floor fire hydrant at that moment.

[0070] In this embodiment, the difference between the water pressure of the top-level water pipe and the water pressure of the top-level fire hydrant at this moment is used as the water pressure compensation amplitude of the top-level fire hydrant at this moment. Among them, under normal circumstances, the water pressure compensation amplitude must be a non-negative number. This embodiment only analyzes the case where the water pressure compensation amplitude is a non-negative number. In the case of a short-term special situation where the water pressure compensation amplitude is a negative number, the opening amplitude of copper ball valve 1 and copper ball valve 2 is not adjusted at the corresponding moment. It should be noted that the situation where the water pressure compensation amplitude is a negative number must be a short-term occurrence. The reason for this is that the water pressure of the top-level fire hydrant has not stabilized temporarily at the corresponding moment, and the water pressure compensation amplitude will automatically return to a non-negative number and remain stable.

[0071] It should be noted that the smaller the water pressure compensation amplitude is, the less help the tap water pressure provides in increasing the water pressure of the top-floor fire hydrants.

[0072] Step S303: obtaining the opening adjustment weight of the copper ball valve 1 at this moment according to the water pressure demand and the water pressure compensation amplitude.

[0073] When the water pressure demand is larger and the water pressure compensation amplitude is smaller, it takes longer for the top fire hydrant to reach the required water pressure. In order to reduce the time, the opening amplitude of the copper ball valve 1 should be larger. Then, according to the water pressure demand and the water pressure compensation amplitude at this moment, this embodiment obtains the opening adjustment weight of the copper ball valve 1 at this moment. The larger the opening adjustment weight, the larger the opening amplitude of the copper ball valve 1 should be at this moment.

[0074] Among them, the calculation formula for opening the adjustment weight is: In the formula, is the opening adjustment weight of copper ball valve 1 at the tth moment; N t is the water pressure demand of the top fire hydrant at the tth moment; ΔP t is the water pressure compensation amplitude of the top fire hydrant at the tth moment; α is the first preset constant, which is greater than 0; norm is the normalization function. The value range is 0 to 1.

[0075] In this embodiment, α is set to 1 to avoid the denominator being 0. The implementer can set the size of α according to actual conditions, which is not limited here.

[0076] Step S304: taking the product of the maximum opening amplitude of the copper ball valve 1 and the opening adjustment weight as the opening amplitude of the copper ball valve 1 at this moment.

[0077] The maximum opening amplitude of the copper ball valve 1 is known. In this embodiment, the opening amplitude of the copper ball valve 1 at this moment is obtained based on the maximum opening amplitude of the copper ball valve 1, that is, the product of the maximum opening amplitude of the copper ball valve 1 and the opening adjustment weight of the copper ball valve 1 at this moment is used as the opening amplitude of the copper ball valve 1 at this moment.

[0078] At this point, the opening amplitude of the copper ball valve 1 at each moment after the fire floor is discovered is obtained in real time.

[0079] The opening amplitude acquisition module 30 of the copper ball valve 2 is used to obtain the opening amplitude of the copper ball valve 2 at each moment according to the opening amplitude of the copper ball valve 1 at each moment, the water flow velocity at each moment and the degree of change of the water flow velocity, the radius of the connected pipe, the water pressure difference between the top-level tap water pipe and the top-level fire hydrant at each moment and the degree of change of the water pressure difference.

[0080] Specifically, in the process of adjusting the opening amplitude of copper ball valve 1, the opening amplitude of copper ball valve 2 should also be adjusted in real time, so as to ensure that the top-floor fire hydrant is connected to the top-floor water pipe. It is known that in the process of initial fire fighting on the fire floor, the opening amplitude of copper ball valve 1 should be greater than the opening amplitude of copper ball valve 2, in order to quickly increase the water pressure of the fire hydrant, and thus the opening amplitude of copper ball valve 2 at each moment is obtained based on the opening amplitude of copper ball valve 1 at each moment in this embodiment. When the water flow velocity at a certain moment is greater and the opening amplitude of the copper ball valve 1 is also greater, it means that the water inflow of the copper ball valve 1 at this moment is greater, which indirectly means that the opening amplitude of the copper ball valve 2 at this moment should be greater; it can be known from the opening amplitude acquisition module 20 of the copper ball valve 1 that when the water pressure difference between the top-level tap water pipe and the top-level fire hydrant at a certain moment is smaller, it can be inferred that at this moment, the water flow rate from the top-level tap water pipe to the top-level fire hydrant pipe is smaller, and the speed of increasing the water pressure in the fire hydrant pipe is slower. In order to increase the water pressure in the fire hydrant pipe, the opening amplitude of the copper ball valve 2 should be larger.

[0081] Considering that after the water pressure rises rapidly in the initial stage of fire fighting, the water pressure of the top fire hydrant and the top water pipe gradually balances, it is necessary to continuously adjust the opening amplitude of copper ball valve 1 and copper ball valve 2 to avoid the unstable or excessive water pressure of the fire hydrant affecting the stable use of the fire extinguishing water gun, and to avoid the excessive water pressure of the fire hydrant causing damage to the fire hydrant pipe. It is known that the water pressure balance of the top fire hydrant and the top water pipe at each moment can be analyzed by the degree of change of the water flow velocity at each moment and the degree of change of the water pressure difference between the top water pipe and the top fire hydrant at each moment. When the degree of change of the water flow velocity at a certain moment is smaller and the degree of change of the water pressure difference between the top water pipe and the top fire hydrant is smaller, it means that the water pressure of the top fire hydrant and the top water pipe at this moment is more balanced. In order to avoid the instability caused by the excessive water pressure of the fire hydrant and damage to the fire hydrant pipe, the opening amplitude of copper ball valve 2 at this moment should be larger, that is, gradually tending to be larger than the opening amplitude of copper ball valve 1.

[0082] Therefore, this embodiment obtains the opening amplitude of the copper ball valve 2 at each moment based on the opening amplitude of the copper ball valve 1 at each moment, the water flow velocity at each moment and the degree of change of the water flow velocity, the radius of the connected pipe, the water pressure difference between the top-level tap water pipe and the top-level fire hydrant at each moment, and the degree of change of the water pressure difference.

[0083] Preferably, in one possible implementation of this embodiment, the method for obtaining the opening amplitude of the copper ball valve 2 is as follows: Figure 4 , which shows a flow chart of a method for obtaining the opening amplitude of a copper ball valve 2 provided in this embodiment, the method comprising the following steps:

[0084] Step S401: For any moment after the fire floor is discovered, the water inflow of the copper ball valve 1 at that moment is obtained according to the opening amplitude of the copper ball valve 1 at that moment, the water flow velocity at that moment and the radius of the connected pipe.

[0085] The calculation formula of water inflow is: S t =v t ×(F 1,t ×πR 2 );where S t is the water inflow of copper ball valve 1 at the tth moment; v t is the water flow velocity at the tth moment; F 1,t is the opening amplitude of the copper ball valve 1 at the tth moment; π is the pi; R is the radius of the connected pipe.

[0086] At this point, the water inflow of the copper ball valve 1 at this moment is obtained.

[0087] Step S402: Obtain the reference opening amplitude of the copper ball valve 2 at this moment according to the water inflow of the copper ball valve 1 at this moment, the water pressure compensation amplitude of the top-level fire hydrant at this moment, and the opening amplitude of the copper ball valve 1 at this moment.

[0088] Among them, the reference opening amplitude of the copper ball valve 2 at this moment must be smaller than the reference opening amplitude of the copper ball valve 1 at this moment, which indirectly indicates that the water pressure of the fire hydrant is in a rapid rising state at this moment.

[0089] Preferably, in a method that can be implemented in this embodiment, the method for obtaining the reference opening amplitude is: according to the water inflow of the copper ball valve 1 at this moment and the water pressure compensation amplitude of the top-level fire hydrant at this moment, obtain the reference adjustment weight at this moment; wherein, the water inflow is positively correlated with the reference adjustment weight, and the water pressure compensation amplitude is negatively correlated with the reference adjustment weight; the larger the reference adjustment weight is, the larger the opening amplitude of the copper ball valve 2 at this moment should be; and then this embodiment uses the product of the opening amplitude of the copper ball valve 1 at this moment and the reference adjustment weight as the reference opening amplitude of the copper ball valve 2 at this moment.

[0090] The calculation formula for reference adjustment weight is: In the formula, γ t is the reference adjustment weight at the tth moment; S t is the water inflow of copper ball valve 1 at the tth moment; ΔP t is the water pressure compensation amplitude of the top-level fire hydrant at the tth moment; β is the second preset constant, which is greater than 0; norm is the normalization function.

[0091] In this embodiment, β is set to 1 to avoid the denominator being 0. The implementer can set the size of β according to actual conditions, which is not limited here.

[0092] Step S403: according to the change degree of the water pressure compensation amplitude and the change degree of the water flow velocity at the moment, the opening correction weight of the copper ball valve 2 at the moment is obtained.

[0093] Considering that the water pressure of the fire hydrant cannot continue to rise rapidly, in order to avoid excessive water pressure causing damage to the fire hydrant pipe, affecting the stable range of the fire extinguishing water gun, and further affecting the fire extinguishing effect. Therefore, this embodiment obtains the opening correction weight of the copper ball valve 2 at this moment according to the degree of change of the water pressure compensation amplitude at this moment and the degree of change of the water flow velocity at this moment, and then corrects the reference opening amplitude of the copper ball valve 2 at this moment, so as to obtain the opening amplitude of the copper ball valve 2 at this moment more accurately. Avoid the situation where the water pressure of the fire hydrant is too high.

[0094] Preferably, in a method that can be implemented in this embodiment, the method for obtaining the opening correction weight is: obtaining the duration corresponding to the time interval between the moment and the previous adjacent moment as the first duration; obtaining the absolute value of the difference between the water pressure compensation amplitude at the moment and the previous adjacent moment as the first difference; taking the ratio of the first difference to the first duration as the degree of change of the water pressure compensation amplitude at the moment; obtaining the absolute value of the difference between the water flow velocity at the moment and the previous adjacent moment as the second difference; taking the ratio of the second difference to the first duration as the degree of change of the water flow velocity at the moment; when the degree of change of the water pressure compensation amplitude and the degree of change of the water flow velocity at the moment are both smaller, it means that at the moment, the water pressure of the top fire hydrant and the water pressure of the water pipe are more likely to be in a balanced state, the water in the water pipe flows more stably into the fire hydrant pipeline, and the water pressure of the top fire hydrant at the moment does not need to be increased, which indirectly means that the opening amplitude of the copper ball valve 2 at the moment should be larger than the opening amplitude of the copper ball valve 1 at the moment, so that the water pressure of the fire hydrant will no longer be increased after reaching the demand but tends to be stable;

[0095] In order to reasonably obtain the opening amplitude of the copper ball valve 2 at this moment, the product of the degree of change of the water pressure compensation amplitude at this moment and the degree of change of the water flow velocity at this moment is negatively correlated and normalized, and used as the opening correction weight of the copper ball valve 2 at this moment. The larger the opening correction weight, the greater the opening degree of the copper ball valve 2 at this moment should be. In this embodiment, the product of the degree of change of the water pressure compensation amplitude at this moment and the degree of change of the water flow velocity at this moment is negatively correlated and normalized by exp(-x), where exp is an exponential function with a natural constant as the base; x represents the product of the degree of change of the water pressure compensation amplitude at this moment and the degree of change of the water flow velocity at this moment.

[0096] Step S404: Correct the reference opening amplitude of the copper ball valve 2 at this moment by using the opening correction weight to obtain the opening amplitude of the copper ball valve 2 at this moment.

[0097] In order to accurately obtain the opening amplitude of the copper ball valve 2 at this moment, the present embodiment corrects the reference opening amplitude of the copper ball valve 2 at this moment by the opening correction weight of the copper ball valve 2 at this moment, and accurately obtains the opening amplitude of the copper ball valve 2 at this moment. The method for obtaining the opening amplitude of the copper ball valve 2 is as follows: the product of the opening correction weight of the copper ball valve 2 at this moment and the reference opening amplitude is used as the corrected opening amplitude of the copper ball valve 2 at this moment; the addition result of the reference opening amplitude of the copper ball valve 2 at this moment and the corrected opening amplitude is used as the opening amplitude of the copper ball valve 2 at this moment.

[0098] At this point, the opening amplitude of the copper ball valve 2 at each moment is obtained.

[0099] The stop module 40 is used to stop adjusting the opening amplitudes of the copper ball valve 1 and the copper ball valve 2 until the opening amplitude of the copper ball valve 2 is larger than the opening amplitude of the copper ball valve 1.

[0100] In the process of adjusting the opening amplitudes of copper ball valve 1 and copper ball valve 2, when the opening amplitude of copper ball valve 2 is larger than that of copper ball valve 1, stop adjusting the opening amplitudes of copper ball valve 1 and copper ball valve 2, so that the water pressure of the fire hydrant remains stable after reaching the required demand, ensuring that the range of the fire extinguishing water gun meets the standard and the water supply is stable, so that the fire floor can be stably and efficiently extinguished.

[0101] It should be noted that the community property is equipped with an appropriate amount of special fire hoses. When the fire floor is detected at the early stage of the fire, the property security personnel or volunteer firefighters will carry special fire hoses to put out the fire on the fire floor. Among them, the special fire hose is a fire hose with a standard length of 25 meters adjusted to a length more suitable for actual use. For example, if the distance between the fire hydrant and the farthest point of the fire floor is 15 meters, the length of the special fire hose is 15 meters, so that it can be deployed and operated more quickly during the initial rescue of the fire. At the same time, a special DC switch water gun equipped with a fast switching valve is selected. The water gun can be opened immediately for fire extinguishing after reaching the fire floor or entering the water gun spray range. After the fire is extinguished, it can also be quickly closed, thereby effectively avoiding uncontrolled large-scale water spraying during the rescue process, and preventing secondary disasters such as flooding to the affected residents and residents downstairs.

[0102] In summary, this embodiment uses a data acquisition module to obtain the fire hydrant water pressure of the floors between the fire floor and the top floor, the water pressure of the top floor water pipe, and the water flow rate of the pipe connecting the top floor fire hydrant and the top floor water pipe. Then, the copper ball valve 1 opening amplitude acquisition module and the copper ball valve 2 opening amplitude acquisition module analyze the data in the data acquisition module to obtain the opening amplitude of the copper ball valve 1 and the opening amplitude of the copper ball valve 2 at each moment until the opening amplitude of the copper ball valve 2 is greater than the opening amplitude of the copper ball valve 1, and then stop adjusting the opening amplitudes of the copper ball valve 1 and the copper ball valve 2. The present invention adjusts the opening amplitudes of the copper ball valve 1 and the copper ball valve 2 in real time, so that while the water pressure of the fire hydrant is rapidly increased, damage to the pipeline caused by excessive water pressure of the fire hydrant is avoided, thereby effectively improving the stability of the fire extinguishing water supply.
