Description

[0002] In modern buildings, fire control technology is the key to ensuring personnel safety and building structural integrity. Fire engines and fire pumps are important components of fire control systems and are usually installed in buildings or other facilities. Specifically, fire engines are used to provide pressurized power to fire pumps to support the fire pumps in pressurizing water flow, so that fire pumps can provide high-pressure water flow to other fire-fighting equipment such as fire hydrants, fire hoses and sprinkler systems when a fire occurs.

[0003] In some related technologies, the fire engine is usually controlled by a pressure switch installed on the fire hydrant to ensure that when a fire occurs, the fire pump can be supported to provide sufficient water pressure and water flow for the fire fighting equipment to extinguish the fire.

DETAILED DESCRIPTION

[0042] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0043] In modern buildings, fire control technology is the key to ensuring personnel safety and building structural integrity. Fire engines and fire pumps are important components of fire control systems and are usually installed in buildings or other facilities. Specifically, fire engines are used to provide fuel to fire pumps to support the fire pumps in pressurizing water flow, so that fire pumps can provide high-pressure water flow to other fire-fighting equipment such as fire hydrants, fire hoses and sprinkler systems when a fire occurs.

[0044] In some related technologies, the fire engine is usually controlled by a pressure switch installed on the fire hydrant to ensure that when a fire occurs, the fire pump can be supported to provide sufficient water pressure and water flow for the fire fighting equipment to extinguish the fire. The above installation method will result in a high installation cost for the fire control system. Based on this, some other technologies use fire detectors such as temperature or smoke sensors to detect fire conditions and replace the pressure switch to start the fire engine to support the fire pump to provide high-pressure water flow.

[0045] However, since fire detectors are prone to false alarms, there may be a problem of fire engines being mistakenly started, resulting in reduced reliability of the fire control system.

[0046] The fire control system provided by the present application is intended to solve the above technical problems of the prior art. Specifically, since the water outlet pressure of the water flow in the fire water outlet network will be reduced after the fire hydrant is turned on, in this solution, a pressure sensor is set on the fire water outlet network connected to the fire water pump, and the fire engine corresponding to the fire water pump is started when the water outlet pressure detected by the pressure sensor meets the preset water pump starting pressure condition, and the fire engine provides pressurized power for the fire water pump, so that the fire water pump can provide high-pressure water flow to the fire hydrant; in the above solution, a pressure sensor is set instead of setting a pressure switch on each fire hydrant, so as to reduce the installation cost of the system; and by automatically judging whether to start the fire engine based on the detected water outlet pressure, pressurized power is provided for the fire water pump, so that the fire water pump can pressurize the water flow and provide high-pressure water flow to the fire hydrant; in the above solution, by judging whether to automatically start the fire engine based on the detected water outlet pressure, the fire water pump is supported to perform pressurization processing, the occurrence of misjudgment caused by other interference conditions is reduced, and the reliability of the fire protection system is improved.

[0047] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0048] Figure 1 A structural diagram of a fire control system provided in an embodiment of the present application Figure 1 .like Figure 1 As shown, the system includes: a fire-fighting unit 10 and a fire-fighting control cabinet 20 ; the fire-fighting unit 10 includes a fire-fighting engine 11 , a fire-fighting water pump 12 , a fire-fighting water outlet network 13 and a pressure sensor 14 .

[0049] Among them, the fire engine 11 is respectively connected to the fire control cabinet 20 and the fire water pump 12; the water outlet of the fire water pump 12 is connected to the water inlet of the fire water outlet network 13, and the multiple water outlets of the fire water outlet network 13 are respectively connected to multiple fire hydrants; the pressure sensor 14 is arranged at the water inlet of the fire water outlet network 13 and connected to the fire control cabinet 20.

[0050] The pressure sensor 14 is used to detect the outlet water pressure of the fire pump 12 and transmit the outlet water pressure to the fire control cabinet 20. The fire control cabinet 20 is used to generate a pressurization signal of the fire engine 11 corresponding to the fire pump 12 according to the outlet water pressure, and transmit the pressurization signal to the fire engine 11; the pressurization signal is used to start the fire engine 11 to provide pressurization power for the fire pump 12, so that the fire pump 12 provides high-pressure water flow to each fire hydrant.

[0051] In some embodiments, the fire engine 11 in the fire control system is used to provide pressurized power, such as fuel power, to the fire water pump 12, so as to support the fire water pump 12 to provide sufficient water source and water pressure to fire hydrants and other fire-fighting equipment after a fire occurs, so that firefighters can quickly control the fire.

[0052] Specifically, the fire engine 11 is connected to the fire pump 12, and the fire pump 12 is also connected to the fire pipeline reserved in the building. When the fire control cabinet 20 detects that the firefighter opens the fire hydrant valve, it controls the fire pump 12 to provide water from the fire pipeline to the fire hydrant through the fire outlet network 13, so that the firefighter sprays the water in the fire hydrant to the fire point through the fire hose.

[0053] In some possible situations, there may be a situation where multiple fire hydrant valves are opened at the same time due to a large fire, or the fire location is at a high terrain and the position of the fire hose outlet connected to the fire hydrant is too high; in the above situation, if the water flow pressure provided by the fire pump 12 is low, it may cause insufficient pressure and the firefighters cannot accurately spray water to the fire point, affecting the fire extinguishing effect; in order to control the fire as soon as possible, when the water flow pressure provided by the fire pump 12 is low, the fire control cabinet 20 can automatically generate a pressurization signal for the fire engine 11 corresponding to the fire pump 12, and transmit the pressurization signal to the fire engine 11 to support the fire pump 12 to provide pressurization power, that is, the fire pump can pressurize the output water flow, and then provide high-pressure water flow to the fire hydrant.

[0054] The above steps can also be explained as the fire control cabinet 20 starts the fire engine, causing the fire pump 12 to pressurize the water to a state higher than the atmospheric pressure, thereby generating a water flow with higher kinetic energy and impact force, so that firefighters can accurately spray the high-pressure water flow in the fire hydrant to the fire point through the fire hose, so as to control the fire and ensure the fire extinguishing effect.

[0055] In a specific embodiment, the pressure sensor 14 can be set to detect the outlet pressure of the fire water pump 12, and then determine whether to automatically start the pressurization signal corresponding to the fire water pump 12 according to the detected outlet pressure. Exemplarily, the pressure sensor 14 can be set at the water inlet of the fire water outlet network 13, and the outlet pressure of the fire water pump 12 can be detected there; the reason is that: in the case where the fire water pump 12 includes multiple water pumps, setting it at the outlet of any water pump in the fire water pump 12 will cause the outlet pressure of other outlets to be missed, reducing the accuracy of the detection result; and, since the pressurized water flow of each water pump will flow into the fire water outlet network 13, the outlet pressure at the entrance of the fire water outlet network 13 can fully detect the outlet pressure of each water pump after pressurization, so as to achieve more accurate detection results, and thus improve the reliability of the fire control system for water flow pressurization control.

[0056] In some optional embodiments, the fire water outlet network 13 includes a main water outlet pipeline and multiple terminal water outlet pipelines; the water inlet of the main water outlet pipeline is connected to the water outlet of the fire water pump 12, and the water outlet of the main water outlet pipeline is respectively connected to the water inlet of each terminal water outlet pipeline, and the water outlet of each terminal water outlet pipeline is respectively connected to the corresponding fire hydrant; the pressure sensor 14 is arranged at the water inlet of the main water outlet pipeline, which is used to detect the total water outlet pressure of each fire water pump 12.

[0057] It can be explained that in some scenarios, a fire pump 12 in the fire control system can provide high-pressure water flow to multiple fire hydrants, so the water flow output by the fire pump 12 can be distributed through multiple branch pipelines ( Figure 1 The water (not shown) flows to each fire hydrant to provide high-pressure water flow thereto.

[0058] When the fire control cabinet 20 detects that the valve of the fire hydrant is open, it can send a pressure detection instruction to the pressure sensor 14 to start monitoring, and simultaneously start to receive the water outlet pressure continuously transmitted by the pressure sensor 14; on this basis, it obtains the starting conditions pre-stored in the fire control cabinet 20; and performs logical judgment on the water outlet pressure according to the starting conditions; when the acquired water outlet pressure meets the above-mentioned starting conditions, it generates a pressurization signal corresponding to the fire engine 11, and transmits the pressurization signal to the fire engine 11, so as to provide pressurization power for the fire water pump 12, so that the fire water pump 12 pressurizes the output water flow and provides high-pressure water flow to each fire hydrant.

[0059] The fire control system provided by the present application is provided with a fire-fighting unit 10 and a fire-fighting control cabinet 20; the fire-fighting unit 10 includes a fire-fighting engine 11, a fire-fighting water pump 12, a fire-fighting water outlet network 13 and a pressure sensor 14; wherein the fire-fighting engine 11 is connected to the fire-fighting control cabinet 20 and the fire-fighting water pump 12 respectively; the water outlet of the fire-fighting water pump 12 is connected to the water inlet of the fire-fighting water outlet network 13, and the multiple water outlets of the fire-fighting water outlet network 13 are respectively connected to multiple fire hydrants; the pressure sensor 14 is arranged at the water inlet of the fire-fighting water outlet network 13 and is connected to the fire-fighting control cabinet 20; since the water outlet pressure in the fire-fighting water outlet network 13 connected thereto will be reduced after the fire hydrant is turned on, the pressure sensor 14 is connected to the fire-fighting water outlet network 13 connected thereto by A pressure sensor 14 is provided on the anti-water outlet pipe network 13, and determines whether to start the fire engine 11 corresponding to the fire water pump 12 through the water outlet pressure detected by the pressure sensor 14 and the preset water pump starting pressure condition, so as to provide pressurized power for the fire water pump 12, so that the fire water pump 12 can provide high-pressure water flow to the fire hydrant; in the above scheme, the fire engine 11 is controlled to start by replacing the pressure switch provided on the fire hydrant with the judgment result of the water outlet pressure, so that the pressure switch on each fire hydrant can be cancelled, thereby reducing the installation cost of the system; and by automatically judging whether to start the fire engine 11 based on the detected water outlet pressure, the occurrence of misjudgment caused by other interference conditions is reduced, thereby improving the reliability of the system.

[0060] Figure 2 A structural diagram of a fire control system provided in an embodiment of the present application Figure 2 The following combination Figure 2 Based on the above implementation, the possible specific structure of the fire control cabinet 20 is further described, but it is not intended to limit the present application.

[0061] like Figure 2 As shown, in an optional embodiment, the fire control cabinet 20 includes an operation console 21 and a memory 22; the operation console 21 and the memory 22 are connected.

[0062] The operating console 21 is used to receive the start-up conditions corresponding to the fire engine 11 input by the user, and transmit the start-up conditions to the memory 22 for storage.

[0063] In some embodiments, the operation console 21 can be understood as an interactive platform for the room delivery control cabinet to interact with the user, which can be, for example, a touch screen, a keyboard and mouse, a display screen, and the like.

[0064] Optionally, after the fire control cabinet 20 is successfully installed, the corresponding firefighting staff can pre-input the starting conditions for starting the fire engine 11 through the operating console 21, and transmit the starting conditions to the memory 22 for storage, so that when judging whether the fire engine 11 needs to start the pressurization signal later, the starting conditions can be directly read and judged, thereby improving the efficiency of judging whether to automatically pressurize, and thereby improving the reliability of the fire control system for water flow pressurization control.

[0065] Continue to see Figure 2 On the basis of the above implementation, the fire control cabinet further includes a controller 23; the controller 23 is respectively connected to the memory 22, the pressure sensor 14 and the fire water pump 12 in the fire control cabinet 20.

[0066] In some embodiments, the pressure sensor 14 transmits the detected water outlet pressure to the controller 23 in the fire control cabinet 20 , and the controller 23 performs the steps of logic judgment and generating a pressurization signal.

[0067] Figure 3 A structural diagram of a fire control system provided in an embodiment of the present application Figure 3 The following combination Figure 3 , the possible specific structure of the fire pump 12 is described, but it is not intended to limit the present application.

[0068] like Figure 3 As shown, in an optional embodiment, the fire engine 11 includes a first engine 111 and a second engine 112; the fire water pump 12 includes a first water pump 121 and a second water pump 122; the first engine 111 corresponds to the first water pump 121, and the second engine 112 corresponds to the second water pump 122; the first engine 111 and the second engine 112 are respectively connected to the controller 23; the water outlets of the first water pump 121 and the second water pump 122 are respectively connected to the water inlet of the fire water outlet network 13; the first water pump 121 and the second water pump 122 are also respectively connected to the controller 23; the startup conditions stored in the memory include the first condition and the second condition.

[0069] The controller 23 is used to read the pre-stored start condition from the memory 22 when receiving the outlet water pressure.

[0070] Optionally, in order to improve computing efficiency, the controller 23 can also synchronously read the starting conditions of the corresponding fire hydrant stored in the controller 23 when it detects that the valve of the fire hydrant is open, and when it receives the water outlet pressure transmitted by the pressure sensor 14, it immediately performs a logical judgment on the water outlet pressure according to the starting conditions to obtain a judgment result of whether to generate a price pressure signal.

[0071] Optionally, if the controller 23 determines that the water pressure meets the starting condition, it generates a pressurization signal and transmits the pressurization signal to the fire engine 11.

[0072] The controller 23 is also used to generate a first pressurization signal when it is determined that the water outlet pressure meets the first condition, and transmit the first pressurization signal to the first engine 111 or the second engine 112, so that the first engine 111 provides pressurization power for the corresponding first water pump 121, or the second engine 112 provides pressurization power for the corresponding second water pump 122.

[0073] Alternatively, the controller 23 is also used to generate a second pressurization signal when it is determined that the water outlet pressure meets the second condition, and transmit the second pressurization signal to the first engine 111 and the second engine 112, so that the first engine 111 provides pressurization power for the corresponding first water pump 121, and the second engine 112 provides pressurization power for the corresponding second water pump 122.

[0074] In order to make the fire control system provided by the present application adapt to more scenarios, the fire water pump 12 can be pre-set to include two or even more groups of engines and corresponding water pumps. Each engine in the fire engine can be connected to the controller respectively, and the water outlet of each water pump in the fire water pump is connected to the water inlet of the fire water outlet network 13 respectively, so as to provide high-pressure water flow within different pressure ranges, provide high-pressure water flow to multiple fire hydrants at the same time, or provide high-pressure water flow to each fire hydrant to meet higher terrain requirements.

[0075] Exemplarily, two groups of engines and water pumps are used for exemplary description in this embodiment, but the two groups of engines and water pumps are not intended to limit the number of water pumps in the fire control system provided in this application.

[0076] Specifically, different starting conditions can be set for different numbers of engines in the fire engine 11. Optionally, a first condition corresponding to starting one engine and a second condition corresponding to starting two engines can be set in advance through the operation console 21, and the first condition and the second condition are pre-stored in the memory 22. Of course, if there are more engines, the number of conditions stored in the memory is also correspondingly more.

[0077] In this embodiment, the first condition includes that the water outlet pressure is in the first pressure interval, and the duration of the water outlet pressure in the first pressure interval is greater than the first preset duration; wherein the first pressure interval includes an interval less than the first pressure threshold and greater than the second pressure threshold; the second condition includes that the water outlet pressure is in the second pressure interval, and the duration of the water outlet pressure in the second pressure interval is greater than the second preset duration; wherein the second pressure interval includes an interval less than the second pressure threshold and greater than the third pressure threshold.

[0078] It can be explained that, in this embodiment, the third pressure threshold is smaller than the second pressure threshold, and the second pressure threshold is smaller than the first pressure threshold; the first preset time length and the second preset time length may be the same time length or different time lengths, and there is no limitation on this.

[0079] Exemplarily, the pressure thresholds and durations corresponding to the first and second conditions in the pre-read start conditions are determined. When the controller 23 detects the water outlet pressure transmitted by the pressure sensor 14, if it is determined that the corresponding pressure value is within the first pressure range, the water outlet pressure is further continuously monitored. After a period of time, when it is determined that the current water outlet pressure meets the first condition, a first pressurization signal is generated, and the first pressurization signal is transmitted to the first engine 111 or the second engine 112 to provide pressurization power to any one of the first water pump 121 or the second water pump 122, so as to start a water pump to pressurize the output water flow and provide high-pressure water flow to the fire hydrant.

[0080] At the same time, the water outlet pressure in the pressure sensor 14 continues to be synchronously detected. When it is found that the corresponding pressure value drops to within the second pressure range, the water outlet pressure is continuously monitored to determine whether the water outlet pressure is an unstable pressure fluctuation or continues to decrease. After a period of time, if it is determined that the current water outlet pressure has been within the second pressure range, it is determined that the second condition is met, and a second pressurization signal is generated. Since one water pump has been started for pressurization processing, the second pressurization signal can be sent only to the other engine in the fire engine 11 to support the other water pump for water flow pressurization, thereby realizing the simultaneous start of two water pumps for pressurization processing and providing high-pressure water flow to the fire hydrant.

[0081] In the above case, or when the second condition is directly met according to the detected water outlet pressure, that is, two engines are directly turned on to support two water pumps for pressurization, the water outlet pressure in the pressure sensor 14 can be continuously monitored. If it is found that the water outlet pressure change is in the first pressure interval and the duration is longer than the first preset time, a first pressurization signal can be generated, and the first engine 111 or the second engine 112 in the fire engine 11 can be automatically shut down based on the first pressurization signal, so as to reduce water resource consumption while ensuring the fire extinguishing effect. In addition, since the fire engine 11 is usually high in power and consumes a lot of electricity when running for a long time, shutting down one engine when the pressure condition is met can reduce energy consumption, thereby reducing operating costs.

[0082] In some optional embodiments, if for some situations where only one engine needs to be turned on to support the corresponding water pump for pressurization treatment to meet the water flow pressurization treatment, if the same engine and water pump are turned on every time, the engine and water pump that are often turned on will reduce the equipment life due to excessive use, and the water pump that is often turned off will cause problems such as rust on the pump body due to being shut down for a long time, affecting the life of the water pump equipment; therefore, in order to extend the service life of the water pump equipment, for the situation where only one engine and water pump are turned on, different engines and corresponding water pumps can be turned on in turn.

[0083] Optionally, the controller 23 is also used to transmit the first pressurization signal to the first engine 111 if it is determined that the first pressurization signal generated currently is the Nth start-up; wherein N is an odd number; the controller 23 is also used to transmit the first pressurization signal to the second engine 112 if it is determined that the first pressurization signal generated currently is the N+1th start-up.

[0084] In some embodiments, the controller 23 may generate a set of historical start records according to the generated pressurization signal and the engine and water pump started corresponding to the pressurization signal each time after generating the pressurization signal, and store the set of historical start records in the memory 22.

[0085] Exemplarily, in the above-mentioned embodiment, in which only one engine is started to provide power for the water pump to pressurize the water flow, the controller 23 can read the historical startup records in the memory 22, and determine which pressurization signal the current pressurization signal is based on the historical startup records; optionally, if it is an odd-numbered pressurization, the first engine 111 is started, and the first water pump 121 is started accordingly to pressurize the water flow; conversely, if it is an even-numbered pressurization, the engine 112 is started, and the second water pump 122 is started accordingly to pressurize the water flow.

[0086] Figure 4 A structural diagram of a fire control system provided in an embodiment of the present application Figure 4 The following combination Figure 4 Based on the above implementation, the possible specific structure of the fire control cabinet 20 is further described, but it is not intended to limit the present application.

[0087] like Figure 4 As shown, in some optional implementations, the fire control cabinet 20 is also provided with an alarm 24; the alarm 24 is connected to the controller 23.

[0088] The controller 23 is further used to generate a fire alarm signal according to the pressurization signal, and transmit the fire alarm signal to the alarm 2424; the alarm 24 is used to issue an alarm prompt for the fire alarm signal.

[0089] Specifically, when the controller 23 generates a pressurization signal according to the water outlet pressure of the pressure sensor 14, it triggers the fire alarm generation instruction, and generates a fire alarm signal according to the instruction; and then transmits the fire alarm signal to the alarm 24; the alarm 24 responds to the fire alarm signal and issues an alarm prompt, so that people around the fire can find the fire and evacuate in time, reducing the loss of people and property. Exemplarily, the alarm 24 can issue an alarm in the form of flashing lights or sounds, and the alarm form of the alarm 24 is not specifically limited in this embodiment.

[0090] Continue to see Figure 4 Based on any of the above implementations, the controller 23 is also connected to the operating console 21.

[0091] The operating console 21 is also used to receive the authority verification information input by the user and transmit the authority verification information to the controller 23; the controller 23 is also used to generate a button state modification instruction in the operating console 21 when it is determined according to the authority control information that the user has the authority to shut down the engine; the button state modification instruction is used to set the engine shutdown button in the operating console 21 to an operable state.

[0092] On this basis, the controller 23 is also used to, when receiving a pressurization stop signal transmitted by the user through the operating console 21, stop the first engine 111 and / or the second engine 112 in the fire engine 11, and correspondingly stop using the first water pump 121 and / or the second water pump 122 in the fire water pump 12 to pressurize the water flow.

[0093] In the above embodiment, when the fire is gradually brought under control, the fire pump 12 can be turned off to save water resources to prevent the fire hydrant from continuing to flow out high-pressure water.

[0094] Of course, in order to avoid misoperation of the fire control cabinet 20 when the fire is not under control, the off button of the fire engine 11 can be set to an inoperable state in advance; if the firefighter wants to operate the off button, authority verification is required in advance.

[0095] Specifically, a user such as a firefighter or an on-duty personnel with the authority to operate the fire control cabinet 20 generates an authority verification request by operating the console 21, and inputs the authority verification request to the controller 23; the controller 23 generates an authority verification interface and displays the interface on the console 21; then the user receives the authority verification information input by the user through the console 21, and the console 21 transmits the authority verification information to the controller 23; the controller 23 verifies the authority verification information according to a preset authority verification logic, and when it is determined that the corresponding user has the authority to shut down the engine through verification, a button state modification instruction is generated, and the engine shutoff button in the console 21 is set to an operable state through the button state modification instruction.

[0096] On this basis, the user operates the close button to generate a corresponding pressurization stop signal and transmits the command value to the controller 23; the controller 23 responds to the pressurization stop signal, shuts down the first engine 111 and the second engine 112 in the fire engine 11 that are in the turned-on state, and correspondingly stops the pressurization processing of the first water pump 121 and / or the second water pump 122 in the fire water pump 12 that are in the pressurized state.
