Description

Technical Field

[0001] The present invention belongs to the technical field of measurement, specifically relates to liquid level measurement, and particularly relates to a method, system and device for detecting the ice layer thickness in a fire pool by radar detection. Background Art

[0002] Water needs to be injected into the fire pool for storage. During the water storage process, it is necessary to detect the ice layer thickness in real time. If the ice layer is too thick, the fire pool will be affected by the volume expansion caused by the freezing of the stored water, resulting in serious water leakage in the fire pool. And after the water injection is completed, pressure needs to be applied to the fire pool to facilitate the subsequent use so that the water can be ejected under high pressure. The pressure needs to be adjusted and controlled according to the volume of water. In the related technology, there is a delay in the detection of the volume of water, resulting in the water level in the fire pool exceeding the maximum water level. At this time, when applying pressure to the fire pool, the pressure will be too high. In addition, the environment around the fire pool will cause the water surface of the fire pool to freeze. The freezing will cause an increase in the volume of water in the fire pool. The delay in the detection of the water volume and the increase in volume caused by freezing will affect the pressure application in the fire pool, resulting in too high pressure and potential safety hazards, and causing water leakage in the fire pool.

[0003] Therefore, for the technical problem of water leakage in the fire pool caused by ice formation in the fire pool, it is necessary to design a method, system and device for detecting the ice layer thickness in a fire pool by radar detection.

[0004] It should be noted that the above information disclosed in this background art part is only used to understand the background art of the concept of this application. Therefore, the above description is not considered as information of the prior art. Summary of the Invention

[0060] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0061] As used herein, phrases such as "in one embodiment", "according to one embodiment", "in some embodiments", etc. generally refer to the fact that a particular feature, structure, or characteristic after such phrase can be included in at least one embodiment of the present disclosure. Thus, a particular feature, structure, or characteristic can be included in more than one embodiment of the present disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, terms such as "example", "exemplary", etc. are used "as an example, instance, or illustration. Any embodiment, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or superior to other embodiments, aspects, or designs. Instead, the use of terms such as "example", "exemplary", etc. is intended to present concepts in a concrete manner.

[0062] In the related art, the amount of water already injected into the fire pool is obtained through a flow meter or the like. However, there will be a delay in the data sent by the flow meter, resulting in the inability to determine in real time whether the amount of water already injected into the fire pool has reached the maximum amount of water. Due to the delay, when it is determined that the maximum amount of water has been reached, the actual amount of water has already exceeded the maximum amount of water. At this time, if pressure is applied to the fire pool, the pressure in the fire pool will exceed the maximum pressure due to the reduction of the remaining space in the fire pool, posing a safety hazard. For example, excessive pressure may cause the fire pool to leak. And because the water stored in the fire pool generally contains sediment in its water quality, it is impossible to use a float valve to control the water level in the fire pool, because the sediment will cause the float valve to become blocked, etc., resulting in the failure of the float valve; the fire pipeline uses a metal pipeline, so it is impossible to add salt or the like to the stored water in the fire pool to prevent the water from freezing, because salt or the like will corrode the metal pipeline.

[0063] The following will, with reference to the accompanying drawings, elaborate on some embodiments of the present invention. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0064] As Figure 1As shown, at least one disclosed embodiment provides a method for detecting the ice layer thickness of a fire pool by radar, including: the control module determines the ice layer thickness according to the reflection of electromagnetic waves emitted by the electromagnetic liquid level gauge into the fire pool, that is, the electromagnetic waves emitted by the electromagnetic liquid level gauge are reflected when contacting the ice surface in the fire pool, are reflected when contacting the water surface, and are reflected when contacting the bottom of the fire pool; the control module obtains the ice layer thickness and the liquid level height according to the time when the electromagnetic waves reflected by the ice surface, the time when the electromagnetic waves reflected by the water surface, and the time when the electromagnetic waves reflected by the bottom of the pool are received; the electromagnetic waves reflected by the ice surface, the electromagnetic waves reflected by the water surface, and the electromagnetic waves reflected by the bottom of the pool have different wavelengths. Therefore, the control module can obtain the ice layer thickness and the liquid level height at this time according to the time points when different wavelengths are received and the time difference when different wavelengths are received; after storing water in the fire pool, the water will freeze due to too low environmental temperature, resulting in the total volume of water and ice at this time being greater than the original stored water volume. The thicker the ice layer, the more the volume increases. If the ice layer is too thick, the fire pool will be squeezed and leak. Therefore, it is necessary to detect the ice layer thickness in real time. If the ice layer thickness exceeds the preset ice layer thickness, an alarm needs to be issued to remind the staff to intervene and de-ice by other means.

[0065] In this embodiment, the actual parameters of the water surface ripples include: fine perimeter, fine amplitude, and fine wavelength.

[0066] In this embodiment, although the ice layer thickness can be predicted according to the possible environmental temperature, it is still necessary to detect the ice layer thickness in real time to avoid the ice layer being too thick.

[0067] In this embodiment, the method for the control module to obtain the ice layer thickness and the liquid level height after freezing can be that when the control module receives the time of the electromagnetic waves reflected by the ice surface as t1, the time of the electromagnetic waves reflected by the liquid level as t2, and the time of the electromagnetic waves reflected by the bottom of the pool as t3, and the propagation speed of the electromagnetic waves in the ice layer is v1 and in the water is v2, then the ice layer thickness h1 = v1×(t2 - t1), and the liquid level height h2 = v2×(t3 - t2).

[0068] In an optional implementation manner, the control module obtains the actual parameters of the water surface ripples according to the water surface image of the fire pool; the control module obtains the volume of the water surface ripples according to the actual parameters of the water surface ripples, and then obtains the total volume of the water in the fire pool in real time, thereby realizing the real-time and accurate detection of the water volume in the fire pool, avoiding the water volume in the fire pool exceeding the maximum height, so as to avoid the danger caused by excessive pressure when pressurizing the fire pool after the water volume exceeds the maximum height.

[0069] In this embodiment, the control module can be electrically connected to a wireless communication module, such as a 5G module, etc., to send the obtained water volume to the upper computer.

[0070] Such asFigure 2 As shown in the figure, in this embodiment, the fire pool can be connected to a water pump, which is controlled by a control module. Water is injected into the fire pool through the water pump, and the control module controls the water pump to stop injecting water after the water level corresponding to the water volume is reached.

[0071] In this embodiment, the control module can also directly send the obtained water surface image to the host computer. The host computer obtains the actual parameters and the total volume of water in the subsequent pool, and then the host computer feeds back a control signal to the control module, and the control module controls the water pump to stop according to the control signal.

[0072] The fire pool is a pool with a cover on the top. The imaging module 3 and the electromagnetic liquid level gauge can be arranged on the inner top surface of the cover. The imaging module 3 can be a camera or the like.

[0073] In an alternative embodiment, the method for the control module to obtain the actual parameters of the water surface ripples based on the water surface image of the fire pool includes: forming ripples on the water surface in the fire pool during the water injection process into the fire pool. The control module controls the imaging module 3 to continuously collect a number of water surface images, and controls the electromagnetic liquid level gauge to detect the precise height of the water surface ripples at the corresponding position. In each water surface image, the rough height of the water surface ripples at the detection position of the electromagnetic liquid level gauge is obtained through image recognition. The adjustment ratio is obtained by dividing the precise height by the rough height at the same position, and the adjustment ratio corresponding to each water surface image is obtained; if the difference between the adjustment ratios corresponding to two adjacent water surface images is within the preset error range, it is determined that the adjustment ratios are all normal, otherwise it is determined that the adjustment ratios are abnormal; when the adjustment ratios are all normal, the average value of all adjustment ratios is obtained as the final adjustment ratio; when the adjustment ratios are abnormal, a number of water surface images are continuously collected again to obtain the adjustment ratio again.

[0074] In this embodiment, after the imaging module 3 takes a water surface image, at this time, the electromagnetic liquid level gauge detects the precise height of the water surface ripples at the corresponding position. The rough height of the water surface ripples at the corresponding detection position of the electromagnetic liquid level gauge is obtained through image recognition and other methods in the water surface image. The adjustment ratio is obtained by dividing the precise height by the rough height, and a corresponding adjustment ratio will be obtained for each water surface image.

[0075] In this embodiment, a preset adjustment ratio range and a preset error range corresponding to the adjustment ratio difference will be preset in the control module. Each obtained adjustment ratio first needs to be within the adjustment ratio range, and at this time, the adjustment ratio is initially normal. Then, the adjustment ratios corresponding to adjacent water surface images are subtracted to obtain an error value. If the error value is within the error range, it is determined that the adjustment ratio is normal.

[0076] In this embodiment, if the adjustment ratio is abnormal, several water surface images are re-acquired and the adjustment ratio is re-acquired. If the adjustment ratio is still abnormal after re-acquiring the water surface image and re-identifying the adjustment ratio, the management personnel are reminded at this time that the camera module 3 or the electromagnetic liquid level gauge may be damaged and need to be checked.

[0077] In an alternative embodiment, the method for the control module to obtain the actual parameters of the water surface ripples based on the water surface image of the fire pool further includes: the actual parameters of the water surface ripples include: precise perimeter, precise amplitude, and precise wavelength; after obtaining the final adjustment ratio, the rough perimeter, rough amplitude, and rough wavelength corresponding to each ripple are obtained through image recognition in the water surface image; the rough perimeter and rough wavelength are both multiplied by the final adjustment ratio to obtain the precise perimeter and precise wavelength; the precise amplitude is obtained by integrating the rough amplitude.

[0078] In this embodiment, the way to obtain the precise amplitude can be to obtain the cross-section of the water surface ripples in the water surface image, divide several vertical lines on the cross-section, the vertical lines are processed through the final adjustment ratio, and the vertical lines are parallel to the vertical lines corresponding to the amplitude. The average value of all processed vertical lines obtained by integration is the precise amplitude A.

[0079] In this embodiment, since the shape of the water surface ripples is only approximately sinusoidal, it is necessary to obtain the actual corresponding precise amplitude A by integration.

[0080] In this embodiment, since the fire pool is provided with a cover plate and will not be affected by other factors during the process of filling water into the fire pool, the ripples formed on the water surface are sinusoidal waves. The trough of the sinusoidal wave is the water surface, and the peak is the highest point of the ripple.

[0081] As Figure 3 and Figure 4 shown, in an alternative embodiment, the method for the control module to obtain the volume of the water surface ripples based on the actual parameters of the water surface ripples includes: the control module constructs a ripple volume model:

[0082] V = W × L × A;

[0083] where, V is the ripple volume; W is the precise perimeter; L is the precise wavelength; A is the precise amplitude.

[0084] In an alternative embodiment, the method for obtaining the volume of water in the fire pool in real time includes: the control module obtains the volume of all the ripples on the water surface, and the volume between the water surface and the inner bottom surface of the fire pool according to the inner bottom area of the fire pool and the precise height corresponding to the lowest point of the sinusoidal wave, so as to obtain the total volume of water in the fire pool.

[0085] In this embodiment, during the water injection process, the water surface image can be obtained in real time. According to the ripple volume model, the volume of each ripple in the water surface image is obtained, and then the sum of the volumes of all ripples is added to the water volume between the water surface and the inner bottom surface of the fire pool, so as to obtain the total volume of water in the fire pool at this time, and then judge in real time whether the total volume of water in the fire pool reaches the maximum volume, so as to avoid the total volume exceeding the maximum volume.

[0086] In this embodiment, the height of the water surface can be recognized from the water surface image, and then adjusted through the final adjustment ratio to obtain the precise height corresponding to the lowest point of the sine wave, that is, the precise height of the water surface, which is convenient for accurately obtaining the water volume between the water surface and the inner bottom surface of the fire pool.

[0087] In an alternative embodiment, the control module obtains the thickness of the ice layer about to form in the fire pool according to the environmental parameters, and then judges whether to stop injecting water into the fire pool according to the total volume of water in the fire pool obtained in real time and the thickness of the ice layer about to form.

[0088] In this embodiment, when the weather is cold, the water surface in the fire pool will freeze. At this time, the sum of the water surface height and the ice thickness will exceed the maximum height of the water surface. Therefore, the influence caused by freezing needs to be considered during the water injection process into the fire pool in winter.

[0089] In this embodiment, the thickness of the ice layer is: ; where h is the ice layer thickness; k is the proportionality coefficient; t is the freezing time. The time when the temperature is continuously equal to or lower than 0 °C within a period of time in the future can be obtained according to the weather forecast, and this period of time is used as the freezing time to predict the thickness of the ice layer that may form in the future, and judge the maximum amount of water that can be injected according to the thickness of the ice layer that may form, so as to avoid the ice layer thickness and the water surface height exceeding the maximum height after freezing.
