TECHNICAL FIELD

[0001] The present application relates to the field of fire-fighting technology, in particular to a fire-fighting remote monitoring system and method based on Internet of Things. BACKGROUND

[0002] When monitoring the water pressure of fire-fighting equipment, the water pressure of the fire-fighting equipment is generally compared with a fixed threshold to determine whether the water pressure in the fire-fighting equipment is low, and further determine whether the fire-fighting equipment has a fault. However, this determination method does not conform to the actual situation. First, the water pressure requirements of fire-fighting equipment at different heights are inconsistent. Second, the municipal water supply pressure is not constant but fluctuates. Therefore, using a fixed threshold to determine whether the water pressure of the fire-fighting equipment is low is prone to incorrect determination. SUMMARY

[0003] Therefore, it is necessary to provide a fire-fighting remote monitoring system and method based on Internet of Things to solve the technical problem that incorrect determination is prone to occur when monitoring the water pressure of fire-fighting equipment.

[0005] In a possible implementation, the correction of the first static water pressure threshold based on the real-time municipal water supply pressure at the location of the fire hydrant comprises: subtracting the average of the all-day municipal water supply pressure at the location of the fire hydrant from the real-time municipal water supply pressure at the location of the fire hydrant to obtain a first pressure difference; adding the first pressure difference to the first static water pressure threshold to obtain the corrected first static water pressure threshold.

[0006] In a possible implementation, the correction of the second static water pressure threshold based on the real-time municipal water supply pressure at the location of the sprinkler system comprises: Subtracting the real-time municipal water supply pressure of the location of the sprinkler system from the average value of the all-day municipal water supply pressure of the location of the sprinkler system to obtain a second pressure difference value; Adding the second hydrostatic pressure threshold value to the second pressure difference value to obtain a corrected second hydrostatic pressure threshold value.

[0007] In a possible implementation, the Internet of Things fire-fighting remote monitoring system further comprises: A liquid level detector arranged at the fire-fighting water tank; The data processor is further configured to receive fire-fighting water tank liquid level data collected by the liquid level detector, and issue a warning if the fire-fighting water tank liquid level data is below a preset water level threshold.

[0008] In a possible implementation, the Internet of Things fire-fighting remote monitoring system further comprises: A video monitoring device arranged at the water pump house; The data processor is further configured to receive video images collected by the video monitoring device, and issue a warning if it is identified that there is water leakage or a fire in the video images.

[0009] In a possible implementation, the first water pressure detector is fixed inside the pipeline of the fire hydrant, and a first filter screen is further fixed to the surface of the first water pressure detector.

[0010] In a possible implementation, the second water pressure detector is fixed inside the pipeline of the sprinkler system, and a second filter screen is further fixed to the surface of the second water pressure detector.

[0011] In a possible implementation, the data processor is further configured to perform fire identification on video images captured by a camera in the area where the sprinkler system is located, and control the sprinkler system to be turned on if a fire is identified.

[0012] In a possible implementation, the data processor is further configured to control a drone carrying a water pipe to fly to the fire area and control an electronic on-off valve on the fire hydrant to be turned on if a fire still exists after the sprinkler system has been turned on for a target duration.

[0013] In a second aspect, the present application further provides an Internet of Things fire-fighting remote monitoring method, which is applied to the system described in any of the above aspects, and the method comprises: The data processor receives the fire hydrant water pressure collected by the first water pressure detector and the spray system water pressure collected by the second water pressure detector, determines the first hydrostatic pressure threshold based on the floor height where the fire hydrant is located, determines the second hydrostatic pressure threshold based on the floor height where the spray system is located, corrects the first hydrostatic pressure threshold based on the real-time municipal water supply pressure at the location of the fire hydrant, and corrects the second hydrostatic pressure threshold based on the real-time municipal water supply pressure at the location of the spray system, determines that the fire hydrant has a fault in the case that the fire hydrant water pressure is less than the corrected first hydrostatic pressure threshold, and determines that the spray system has a fault in the case that the spray system water pressure is less than the corrected second hydrostatic pressure threshold.

[0021] In this document, the reference to "embodiments" means that the particular feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears at various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily mutually exclusive of other embodiments. It is explicitly and implicitly understood that the embodiments described herein can be combined with other embodiments.

[0022] The present application provides an Internet of Things fire-fighting remote monitoring system and method, which are described below respectively.

[0023] As shown in Figure 1 The present application provides an Internet of Things fire-fighting remote monitoring system, which comprises: A first water pressure detector 101 arranged at a fire hydrant; A second water pressure detector 102 arranged at a sprinkler system; The data processor 103 is configured to receive the fire hydrant water pressure collected by the first water pressure detector 101 and the spray system water pressure collected by the second water pressure detector 102, determine a first hydrostatic pressure threshold based on the floor height where the fire hydrant is located, determine a second hydrostatic pressure threshold based on the floor height where the spray system is located, correct the first hydrostatic pressure threshold based on the real-time municipal water supply pressure at the location of the fire hydrant, correct the second hydrostatic pressure threshold based on the real-time municipal water supply pressure at the location of the spray system, and determine that the fire hydrant is faulty when the fire hydrant water pressure is less than the corrected first hydrostatic pressure threshold, and determine that the spray system is faulty when the spray system water pressure is less than the corrected second hydrostatic pressure threshold.

[0024] It can be understood that the hydrostatic pressure refers to the vertical force exerted on the contact surface of a stationary fluid (such as a liquid) by its own gravity. The number of first water pressure detectors 101 can be multiple, and the number of fire hydrants can also be multiple, with one first water pressure detector 101 arranged for each fire hydrant. Similarly, the number of second water pressure detectors 102 can also be multiple, and the number of spray systems can also be multiple, with one second water pressure detector 102 arranged for each spray system.

[0025] Generally, each floor of a building is configured with a fire hydrant, and each fire hydrant is configured with a unique identification code. By identifying the identification code, the floor where the corresponding fire hydrant is located can be determined. According to the floor where the fire hydrant is located and the floor height of each floor, the height of the fire hydrant from the ground can be determined, and according to the height, the hydrostatic pressure required by the fire hydrant can be determined as the hydrostatic pressure threshold.

[0026] The normal water pressure range of a fire hydrant is between 0.3-0.6Mpa. Generally speaking, the higher the floor, the lower the corresponding water pressure, but as long as it is within the normal water pressure range, it is allowed. Therefore, the hydrostatic pressure threshold of a low floor will be larger than that of a high floor. Considering the actual situation, the hydrostatic pressure thresholds of different floors will be different, and the specific threshold can be set according to the floor, as long as the aforementioned requirements are met.

[0027] In addition, the municipal water supply pressure may also be different at different time periods. For example, during the peak water usage period, the municipal water supply pressure will decrease, while during the low water usage period, the municipal water supply pressure will increase. Therefore, the fluctuation of the municipal water supply pressure will also affect the water pressure monitoring of the fire hydrant and the spray system. In order to reduce the influence of the fluctuation of the municipal water pressure on the water pressure monitoring, the hydrostatic pressure threshold is corrected according to the real-time municipal water supply pressure.

[0028] The present application adjusts the hydrostatic pressure threshold for water pressure monitoring in real time according to the actual situation of the fire hydrant and the spray system, so that the water pressure monitoring result is more accurate.

[0029] In some embodiments, the first hydrostatic pressure threshold is corrected based on a real-time municipal water supply pressure at the hydrant site, including: Subtracting the real-time municipal water supply pressure at the hydrant site from an all-day municipal water supply pressure average at the hydrant site to obtain a first pressure difference value; Adding the first hydrostatic pressure threshold and the first pressure difference value to obtain a corrected first hydrostatic pressure threshold.

[0030] It can be understood that the all-day municipal water supply pressure average at the hydrant site can be an average value obtained according to the municipal water supply pressure corresponding to the whole point time in a day. When the first pressure difference value is positive, it indicates that the municipal water supply pressure at the current time is large, and therefore the first hydrostatic pressure threshold is increased. Conversely, when the first pressure difference value is negative, it indicates that the municipal water supply pressure at the current time is small, and therefore the first hydrostatic pressure threshold is decreased. By dynamically adjusting the first hydrostatic pressure threshold, the monitoring and judgment of water pressure are more accurate.

[0031] In some embodiments, the second hydrostatic pressure threshold is corrected based on a real-time municipal water supply pressure at the sprinkler system site, including: Subtracting the real-time municipal water supply pressure at the sprinkler system site from an all-day municipal water supply pressure average at the sprinkler system site to obtain a second pressure difference value; Adding the second hydrostatic pressure threshold and the second pressure difference value to obtain a corrected second hydrostatic pressure threshold.

[0032] It can be understood that the all-day municipal water supply pressure average at the sprinkler system site can be an average value obtained according to the municipal water supply pressure corresponding to the whole point time in a day. When the second pressure difference value is positive, it indicates that the municipal water supply pressure at the current time is large, and therefore the second hydrostatic pressure threshold is increased. Conversely, when the second pressure difference value is negative, it indicates that the municipal water supply pressure at the current time is small, and therefore the second hydrostatic pressure threshold is decreased. By dynamically adjusting the second hydrostatic pressure threshold, the monitoring and judgment of water pressure are more accurate.

[0033] In some embodiments, the Internet of Things fire-fighting remote monitoring system further includes: A liquid level detector 104 arranged at the fire-fighting water tank; The data processor 103 is further configured to receive fire-fighting water tank liquid level data collected by the liquid level detector 104, and issue a warning if the fire-fighting water tank liquid level data is lower than a preset water level threshold.

[0034] It can be understood that the fire water tank is generally arranged on the roof, and the fire water tank can be connected with the fire water supply pipeline to fill the pipeline with water. When the water level in the fire water tank is below a threshold value, there is a fire safety hazard, and at this time, a warning needs to be given to check whether the fire water tank has a water leakage or the like.

[0035] In some embodiments, the Internet of Things fire remote monitoring system further comprises: a video monitoring device arranged in the water pump room; The data processor 103 is further configured to receive a video image collected by the video monitoring device and issue a warning when identifying that there is a water leakage or a fire in the video image.

[0036] It can be understood that in the present embodiment, a neural network model can be used to identify the water leakage or fire area in the image. Specifically, sample images labeled with water leakage areas and fire areas are obtained, the sample images are input into a semantic segmentation model U-Net for training, and the trained model is used to identify the images to be identified to determine the water leakage or fire area.

[0037] In some embodiments, the first water pressure detector 101 is fixed inside the pipeline of the fire hydrant, and a first filter screen is further fixed on the surface of the first water pressure detector 101.

[0038] The second water pressure detector 102 is fixed inside the pipeline of the sprinkler system, and a second filter screen is further fixed on the surface of the second water pressure detector 102.

[0039] It can be understood that the water flow in the pipeline contains some stone particles or metal particles, which can damage the water pressure detector over time. Therefore, a filter screen is arranged outside the water pressure detector to ensure the safety of the water pressure detector and prolong the service life of the water pressure detector.

[0040] In some embodiments, the data processor 103 is further configured to perform fire identification on a video image captured by a camera in the area where the sprinkler system is located, and control the sprinkler system to start when a fire is identified.

[0041] It can be understood that when a fire is identified, the sprinkler system is controlled to start to extinguish the fire in time and prevent the fire from spreading.

[0042] In some embodiments, the data processor 103 is further configured to control a drone carrying a water pipe to fly to a fire area and control an electronic on-off valve on the fire hydrant to open when a fire still exists after the sprinkler system has been opened for a target duration.

[0043] It can be understood that, after the control of the sprinkler system is opened when the fire is identified, if the fire has not been extinguished, it is necessary to continue to increase the fire-fighting strength, and the unmanned aerial vehicle is controlled to take a water pipe to extinguish the fire.

[0044] The application further provides a fire-fighting remote monitoring method of the Internet of Things, which is applied to the system. Figure 2 As shown in the figure, the method comprises the following steps: S201, the data processor 103 receives the water pressure of the fire hydrant collected by the first water pressure detector 101 and the water pressure of the sprinkler system collected by the second water pressure detector 102, determines the first static water pressure threshold based on the floor height where the fire hydrant is located, and determines the second static water pressure threshold based on the floor height where the sprinkler system is located; S202, the data processor 103 corrects the first static water pressure threshold based on the real-time municipal water supply pressure of the site where the fire hydrant is located, and corrects the second static water pressure threshold based on the real-time municipal water supply pressure of the site where the sprinkler system is located; S203, the data processor 103 determines that the fire hydrant has a fault in the case that the water pressure of the fire hydrant is less than the corrected first static water pressure threshold, and determines that the sprinkler system has a fault in the case that the water pressure of the sprinkler system is less than the corrected second static water pressure threshold.

[0045] The fire-fighting remote monitoring system and method of the Internet of Things provided by the application are described in detail above, and the principles and implementation modes of the application are described by applying specific examples in this paper. The above example is only used to help understand the method and core idea of the application. Meanwhile, for those skilled in the art, according to the idea of the application, the specific implementation mode and application range will be changed, and the above description should not be understood as a limitation of the application.
