Description

Technical Field

[0001] This invention relates to the field of data processing technology, and specifically to a method and system for monitoring the status of fire-fighting equipment. Background Technology

[0002] Firefighting equipment can reduce losses caused by fire through prevention and control measures. However, if firefighting equipment fails or is not properly maintained, it is difficult to prevent the escalation of a fire. Therefore, firefighting equipment is usually inspected manually or automatically to detect and eliminate any abnormalities in advance.

[0003] However, existing manual or automatic monitoring technologies can often only detect relatively serious anomalies, such as damaged water pumps, fire hydrants, or severe pipe ruptures in fire water supply systems. They struggle to detect minor, incremental anomalies such as pump impeller wear, reduced interface sealing, or minor pipe ruptures. If these minor, incremental anomalies are not detected and addressed promptly, they may eventually lead to qualitative changes, developing into serious anomalies and thus affecting the effectiveness of fire protection systems in responding to fire incidents. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a method and system for monitoring the status of fire-fighting devices, which can detect minor, quantitative anomalies in fire-fighting devices, prevent them from becoming serious anomalies and causing serious fire accidents, and effectively ensure the reliability of fire-fighting devices.

[0005] The technical solution adopted in this invention is as follows:

[0006] A method for monitoring the status of a fire-fighting device includes the following steps: when the fire-fighting device is activated, acquiring the protection parameters and evaluation parameters of the fire-fighting device; determining whether the protection parameters are normal; if the protection parameters are normal, acquiring the status of the fire-fighting device based on the characteristics of the evaluation parameters.

[0007] Obtaining the status of the fire-fighting device based on the characteristics of the evaluation parameters specifically includes: retrieving the correspondence between the characteristics of the evaluation parameters and the status prompt items; obtaining the status prompt items of the fire-fighting device based on the characteristics of the evaluation parameters and the correspondence; and displaying the status prompt items.

[0008] The fire-fighting device includes a fire hydrant system, the protection parameters include motor speed and valve status, the evaluation parameters include water pressure in the fire hydrant, and the characteristics of the evaluation parameters include target pressure value, pressure rise time and pressure holding time.

[0009] The correspondence between the characteristics of the evaluation parameters and the status prompts includes: When the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is less than or equal to the first preset time, and the pressure holding time is greater than or equal to the second preset time, the corresponding status prompt is "normal"; when the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is greater than the first preset time, and the pressure holding time is greater than or equal to the second preset time, the corresponding status prompt is "pump impeller wear"; when the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is less than or equal to the first preset time, and the pressure holding time is less than the second preset time, the corresponding status prompt is "poor seal or slight leakage"; when the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is greater than the first preset time, and the pressure holding time is less than the second preset time, the corresponding status prompt is "general leakage"; when the water pressure in the fire hydrant does not reach the target pressure value, the corresponding status prompt is "serious leakage".

[0010] When the status indication of the fire-fighting device is "not sealed properly" or "slight leakage", in addition to displaying the status indication, the system also includes: linearly adjusting the opening of the preset valve and detecting the water pressure in the fire hydrant in real time during the adjustment process; plotting a corresponding curve based on the real-time detected water pressure in the fire hydrant to determine the location of the not sealed properly or "slight leakage" based on the curve.

[0011] A status monitoring system for a fire-fighting device includes: a first acquisition module, configured to acquire protection parameters and evaluation parameters of the fire-fighting device when the fire-fighting device is activated; a judgment module, configured to judge whether the protection parameters are normal; and a second acquisition module, configured to acquire the status of the fire-fighting device based on the characteristics of the evaluation parameters when the protection parameters are normal.

[0012] The second acquisition module is specifically used for: retrieving the correspondence between the features of the evaluation parameters and the status prompts; acquiring the status prompts of the fire-fighting device based on the features of the evaluation parameters and the correspondence; and displaying the status prompts.

[0013] The fire-fighting device includes a fire hydrant system, the safeguard parameters include motor speed and valve status, and the evaluation parameters include water pressure inside the fire hydrant.

[0014] The correspondence between the characteristics of the evaluation parameters and the status prompts includes: When the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is less than or equal to the first preset time, and the pressure holding time is greater than or equal to the second preset time, the corresponding status prompt is "normal"; when the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is greater than the first preset time, and the pressure holding time is greater than or equal to the second preset time, the corresponding status prompt is "impeller wear"; when the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is less than or equal to the first preset time, and the pressure holding time is less than the second preset time, the corresponding status prompt is "poor seal or slight leakage"; when the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is greater than the first preset time, and the pressure holding time is less than the second preset time, the corresponding status prompt is "general leakage"; when the water pressure in the fire hydrant does not reach the target pressure value, the corresponding status prompt is "serious leakage".

[0015] When the second acquisition module obtains the status prompt item of the fire-fighting device as "not sealed properly" or "slight leakage", in addition to displaying the status prompt item, it also linearly adjusts the opening degree of the preset valve, and detects the water pressure in the fire hydrant in real time during the adjustment process, and draws a corresponding curve based on the real-time detected water pressure in the fire hydrant, so as to determine the location of the not sealed properly or "slight leakage" based on the curve.

[0016] The beneficial effects of this invention are:

[0017] This invention obtains the protection parameters and evaluation parameters of the fire protection device, and when the protection parameters are normal, it obtains the status of the fire protection device based on the characteristics of the evaluation parameters when the fire protection device is activated. In this way, it can monitor the minor and quantitative anomalies of the fire protection device, prevent them from becoming serious anomalies and causing serious fire accidents, and effectively ensure the reliability of the fire protection device. Attached Figure Description

[0018] Figure 1 This is a flowchart of a fire protection device status monitoring method according to an embodiment of the present invention;

[0019] Figure 2 This is a block diagram of the status monitoring system of the fire protection device according to an embodiment of the present invention. Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1 As shown, the status monitoring method for fire-fighting devices according to an embodiment of the present invention includes the following steps:

[0022] S1, when the fire protection device is activated, acquires the protection parameters and evaluation parameters of the fire protection device.

[0023] The fire protection device operation mentioned here can refer to the operation of the fire protection device during regular or irregular self-inspection or manual inspection. Support parameters refer to the operating parameters that maintain the operation of the fire protection device, while evaluation parameters refer to the parameters that can be detected when the fire protection device is activated and can reflect minor, quantitative anomalies in the fire protection device.

[0024] Firefighting equipment may include fire hydrant systems, smoke exhaust systems, and overpressure control systems. This embodiment of the invention uses a fire hydrant system as an example for detailed explanation. A fire hydrant system mainly includes a fire pump, fire hydrants, a pipe network, and necessary valves. The fire pump is driven by a motor, drawing water from a water source and transporting it to the fire hydrant through the pipe network. For a fire hydrant system, the safeguard parameters include motor speed and valve status, and the evaluation parameters include the water pressure inside the fire hydrant, which can be detected at the fire hydrant inlet.

[0025] S2, determine whether the protection parameters are normal.

[0026] Ensuring normal parameters means ensuring that the parameters are in the preset state, value, or range so that the fire protection equipment can operate normally.

[0027] For fire hydrant systems, the motor speed should be set to a preset value, the hydrant valve at the fire hydrant should be set to closed, and the outlet valve of the fire pump should be set to open during the pressurization phase and closed during the pressure holding phase after pressurization. If the motor speed is at or close to the preset value, and all the above valves are in the corresponding state, the protection parameters can be considered normal; otherwise, the subsequent state judgment should be suspended, and the process should be continued after appropriate adjustments are made.

[0028] S3. If the parameters are normal, the status of the fire protection device is obtained based on the characteristics of the evaluation parameters.

[0029] For the evaluation parameter of water pressure within a fire hydrant system, the characteristics of the evaluation parameter include the target pressure value, the pressure rise time, and the pressure holding time. The pressure rise time refers to the time consumed from the successful start of the fire pump until the water pressure within the fire hydrant reaches the target pressure value; the pressure holding time refers to the time consumed from the stable shutdown of the fire pump and the closure of its outlet valve until the water pressure within the fire hydrant drops to the lower limit of the set pressure value.

[0030] Specifically, the correspondence between the characteristics of the evaluation parameters and the status prompts can be retrieved first, and then the status prompts of the fire protection device can be obtained based on the characteristics of the evaluation parameters and the correspondence.

[0031] In one embodiment of the present invention, the correspondence between the characteristics of the evaluation parameters and the status prompts may include: (1) when the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is less than or equal to the first preset time, and the pressure holding time is greater than or equal to the second preset time, the corresponding status prompt is normal; (2) when the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is greater than the first preset time, and the pressure holding time is greater than or equal to the second preset time, the corresponding status prompt is water pump impeller wear; (3) when the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is less than or equal to the first preset time, and the pressure holding time is less than the second preset time, the corresponding status prompt is poor sealing or slight leakage; (4) when the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is greater than the first preset time, and the pressure holding time is less than the second preset time, the corresponding status prompt is general leakage; (5) when the water pressure in the fire hydrant does not reach the target pressure value, the corresponding status prompt is serious leakage. Among them, general leakage is also a significant leakage, but its severity is between slight leakage and serious leakage. The water pressure in the fire hydrant has not reached the target pressure value. This means that the water pressure in the fire hydrant has not reached the target pressure value since the fire pump started running successfully for three preset times. The third preset time is much longer than the first preset time, for example, it can be set to 5 times the first preset time.

[0032] In one specific embodiment of the present invention, the correspondence between the features of the evaluation parameters and the status prompts can be stored and retrieved in a form such as Table 1.

[0033] Table 1

[0034] water pressure boost time Pressure holding time Status prompts ≥0.6MPa ≤55s ≥30min normal ≥0.6MPa ＞55s ≥30min Water pump impeller wear ≥0.6MPa ≤55s <30min Inadequate sealing / minor leakage ≥0.6MPa ＞55s <30min General leaks <0.6MPa / / Serious leak

[0035] Finally, status prompts can be displayed, for example, through the monitoring personnel's terminal, so that the monitoring personnel can know the status of the fire protection equipment.

[0036] The above-mentioned status prompts can indicate what abnormal state the fire protection device may be in. In this embodiment of the invention, the two most important issues are water pump impeller wear and poor sealing / minor leakage. The ability to provide early warning for these two abnormalities is the core difference between this invention and the relevant monitoring functions in the prior art.

[0037] Poor sealing or minor leakage may be caused by hardening or cracking of the rubber gasket at the valve or interface of the fire hydrant, or minor cracks in the pipe itself. In one embodiment of the present invention, when the obtained status indication of the fire-fighting device is poor sealing or minor leakage, in addition to displaying the status indication, the opening degree of the preset valve can be linearly adjusted, and the water pressure in the fire hydrant can be detected in real time during the adjustment process. A corresponding curve is plotted based on the real-time detected water pressure in the fire hydrant to determine the location of poor sealing or minor leakage based on the curve.

[0038] In one specific embodiment of the present invention, a preset valve can be installed on the pipeline downstream of the outlet valve of the fire pump. First, the inlet valve and all valves inside the fire pump can be closed, and the outlet valve of the fire pump and all other related valves in the pipeline network can be opened. Then, the opening of the preset valve is linearly increased, while simultaneously acquiring and plotting the water pressure curve inside the fire hydrant in real time, until the water pressure inside the fire hydrant is 0 or close to 0. Finally, the curve can be displayed on the monitoring personnel's terminal so that the location of the leak or slight leakage can be manually determined, or the system can automatically determine the location of the leak or slight leakage based on the curve. Taking a curve with time on the horizontal axis and pressure on the vertical axis as an example, when the curve is a smooth, linear decline, the location of the leak or slight leakage can be determined to be the pipeline; when the curve first declines at a relatively fast speed and then at a slower speed, with a clear inflection point between the two, the location of the leak or slight leakage can be determined to be the fire hydrant; when the curve is a sudden drop approaching a vertical line, the location of the leak or slight leakage can be determined to be the check valve at the fire pump.

[0039] Therefore, it can not only detect abnormalities such as poor sealing or minor leakage in the fire hydrant system, but also roughly determine the location of the abnormality, making it easier for managers to quickly locate and eliminate the abnormality.

[0040] According to the fire protection device status monitoring method of the present invention, by acquiring the protection parameters and evaluation parameters of the fire protection device, and when the protection parameters are normal, the status of the fire protection device is obtained based on the characteristics of the evaluation parameters when the fire protection device is activated. Thus, it is possible to monitor minor, quantitative anomalies of the fire protection device, prevent them from becoming serious anomalies and causing serious fire accidents, and effectively ensure the reliability of the fire protection device.

[0041] Corresponding to the status monitoring method of the fire-fighting device in the above embodiments, the present invention also proposes a status monitoring system for the fire-fighting device.

[0042] like Figure 2As shown, the fire protection device status monitoring system of this embodiment includes a first acquisition module 10, a judgment module 20, and a second acquisition module 30. The first acquisition module 10 is used to acquire the protection parameters and evaluation parameters of the fire protection device when it is activated; the judgment module 20 is used to judge whether the protection parameters are normal; the second acquisition module 30 is used to acquire the status of the fire protection device based on the characteristics of the evaluation parameters when the protection parameters are normal.

[0043] The fire protection device operation mentioned here can refer to the operation of the fire protection device during regular or irregular self-inspection or manual inspection. Support parameters refer to the operating parameters that maintain the operation of the fire protection device, while evaluation parameters refer to the parameters that can be detected when the fire protection device is activated and can reflect minor, quantitative anomalies in the fire protection device.

[0044] Firefighting equipment may include fire hydrant systems, smoke exhaust systems, and overpressure control systems. This embodiment of the invention uses a fire hydrant system as an example for detailed explanation. A fire hydrant system mainly includes a fire pump, fire hydrants, a pipe network, and necessary valves. The fire pump is driven by a motor, drawing water from a water source and transporting it to the fire hydrant through the pipe network. For a fire hydrant system, the safeguard parameters include motor speed and valve status, and the evaluation parameters include the water pressure inside the fire hydrant, which can be detected at the fire hydrant inlet.

[0045] Ensuring normal parameters means ensuring that the parameters are in the preset state, value, or range so that the fire protection equipment can operate normally.

[0046] For fire hydrant systems, the motor speed should be set to a preset value, the hydrant valve at the fire hydrant should be set to closed, and the outlet valve of the fire pump should be set to open during the pressurization phase and closed during the pressure holding phase after pressurization. If the motor speed is at or close to the preset value, and all the above valves are in the corresponding state, the protection parameters can be considered normal; otherwise, the subsequent state judgment should be suspended, and the process should be continued after appropriate adjustments are made.

[0047] For the evaluation parameter of water pressure within a fire hydrant system, the characteristics of the evaluation parameter include the target pressure value, the pressure rise time, and the pressure holding time. The pressure rise time refers to the time consumed from the successful start of the fire pump until the water pressure within the fire hydrant reaches the target pressure value; the pressure holding time refers to the time consumed from the stable shutdown of the fire pump and the closure of its outlet valve until the water pressure within the fire hydrant drops to the lower limit of the set pressure value.

[0048] Specifically, the second acquisition module 30 can first retrieve the correspondence between the characteristics of the evaluation parameters and the status prompts, and then obtain the status prompts of the fire protection device based on the characteristics of the evaluation parameters and the correspondence.

[0049] In one embodiment of the present invention, the correspondence between the characteristics of the evaluation parameters and the status prompts may include: (1) when the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is less than or equal to the first preset time, and the pressure holding time is greater than or equal to the second preset time, the corresponding status prompt is normal; (2) when the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is greater than the first preset time, and the pressure holding time is greater than or equal to the second preset time, the corresponding status prompt is water pump impeller wear; (3) when the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is less than or equal to the first preset time, and the pressure holding time is less than the second preset time, the corresponding status prompt is poor sealing or slight leakage; (4) when the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is greater than the first preset time, and the pressure holding time is less than the second preset time, the corresponding status prompt is general leakage; (5) when the water pressure in the fire hydrant does not reach the target pressure value, the corresponding status prompt is serious leakage. Among them, general leakage is also a significant leakage, but its severity is between slight leakage and serious leakage. The water pressure in the fire hydrant has not reached the target pressure value. This means that the water pressure in the fire hydrant has not reached the target pressure value since the fire pump started running successfully for three preset times. The third preset time is much longer than the first preset time, for example, it can be set to 5 times the first preset time.

[0050] In one specific embodiment of the present invention, the correspondence between the features of the evaluation parameters and the status prompts can be stored and retrieved in a form such as Table 1.

[0051] Finally, the second acquisition module 30 can display status prompts, for example, through the monitoring personnel's terminal, so that the monitoring personnel can know the status of the fire protection device.

[0052] The above-mentioned status prompts can indicate what abnormal state the fire protection device may be in. In this embodiment of the invention, the two most important issues are water pump impeller wear and poor sealing / minor leakage. The ability to provide early warning for these two abnormalities is the core difference between this invention and the relevant monitoring functions in the prior art.

[0053] Poor sealing or minor leakage may be caused by hardening or cracking of the rubber gasket at the valve or interface of the fire hydrant, or minor cracks in the pipe itself. In one embodiment of the present invention, when the acquired status indication of the fire-fighting device is poor sealing or minor leakage, the second acquisition module 30, in addition to displaying the status indication, can also linearly adjust the opening of the preset valve, and during the adjustment process, detect the water pressure in the fire hydrant in real time, and draw a corresponding curve based on the real-time detected water pressure in the fire hydrant, so as to determine the location of poor sealing or minor leakage based on the curve.

[0054] In one specific embodiment of the present invention, a preset valve can be installed on the pipeline downstream of the outlet valve of the fire pump. First, the inlet valve and all valves inside the fire pump can be closed, and the outlet valve of the fire pump and all other related valves in the pipeline network can be opened. Then, the opening of the preset valve is linearly increased, while simultaneously acquiring and plotting the water pressure curve inside the fire hydrant in real time, until the water pressure inside the fire hydrant is 0 or close to 0. Finally, the curve can be displayed on the monitoring personnel's terminal so that the location of the leak or slight leakage can be manually determined, or the system can automatically determine the location of the leak or slight leakage based on the curve. Taking a curve with time on the horizontal axis and pressure on the vertical axis as an example, when the curve is a smooth, linear decline, the location of the leak or slight leakage can be determined to be the pipeline; when the curve first declines at a relatively fast speed and then at a slower speed, with a clear inflection point between the two, the location of the leak or slight leakage can be determined to be the fire hydrant; when the curve is a sudden drop approaching a vertical line, the location of the leak or slight leakage can be determined to be the check valve at the fire pump.

[0055] Therefore, it can not only detect abnormalities such as poor sealing or minor leakage in the fire hydrant system, but also roughly determine the location of the abnormality, making it easier for managers to quickly locate and eliminate the abnormality.

[0056] The fire protection device status monitoring system according to an embodiment of the present invention acquires the protection parameters and evaluation parameters of the fire protection device, and when the protection parameters are normal, acquires the status of the fire protection device based on the characteristics of the evaluation parameters when the fire protection device is activated. Thus, it can detect minor, quantitative anomalies of the fire protection device, prevent them from becoming serious anomalies and causing serious fire accidents, and effectively ensure the reliability of the fire protection device.

When the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is greater than the first preset time, and the pressure holding time is greater than or equal to the second preset time, the corresponding status prompt is impeller wear. When the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is less than or equal to the first preset time, and the pressure holding time is less than the second preset time, the corresponding status prompt is "not sealed properly or slightly leaking". When the water pressure in the fire hydrant reaches the target pressure value, and the pressure rise time is greater than the first preset time, and the pressure holding time is less than the second preset time, the corresponding status prompt is "general leakage". The water pressure in the fire hydrant has not reached the target pressure value, and the corresponding status message is "serious leakage".

10. The status monitoring system for fire-fighting equipment according to claim 9, characterized in that, When the second acquisition module obtains the status prompt item of the fire-fighting device as "not sealed properly" or "slight leakage", in addition to displaying the status prompt item, it also linearly adjusts the opening degree of the preset valve, and detects the water pressure in the fire hydrant in real time during the adjustment process, and draws a corresponding curve based on the real-time detected water pressure in the fire hydrant, so as to determine the location of the not sealed properly or "slight leakage" based on the curve.
