Description

Technical Field

[0001] The present application relates to the field of water pumps, and in particular to an intelligent water pump data early warning system. Background Art

[0002] Water pumps are widely used in modern industry. During the operation of water pumps, intelligent data early warning systems are usually used to monitor the operation of water pumps to ensure the normal operation of water pumps. However, existing intelligent water pump data early warning systems usually have the following defects:

[0003] 1. The monitoring module (or sensor) of the existing intelligent water pump data warning system often needs to be integrated with the water pump. When the data warning is performed on the existing water pump system, cumbersome modification projects are required. When the data warning is not required, it needs to be modified again.

[0004] 2. The existing intelligent water pump data early warning system usually uses a water level gauge with a single buoy to monitor the water level data of the water pump. However, the single buoy is greatly affected by the fluctuation of the water surface, resulting in frequent fluctuations in the water level data, which is not conducive to the analysis and early warning of the water level data.

[0005] 3. Currently, the intelligent water pump data warning system also performs monitoring and warning based on the collected water surface image signals. However, the image signals are easily affected by the reflection of the water surface, making them difficult to identify, or additional complex image data processing is required to eliminate the influence of the reflection.

[0016] Furthermore, the positioning ball also includes a first positioning ball;

[0017] The number of first positioning balls is 4, and the first positioning balls are arranged at different positions on the same horizontal plane of the main support;

[0018] The image tracking module includes a first image tracking module, which is arranged on the top or above the wall of the water storage tank; the first image tracking module is used to track the first positioning ball and obtain liquid level change data according to the height change value of the first positioning ball in the vertical direction;

[0022] The image tracking module also includes a second image tracking module, which is arranged on the main support; the second image tracking module is used to track the second positioning ball and obtain liquid level fluctuation data according to the height value of the second positioning ball in the vertical direction;

[0023] Liquid level fluctuation data including average fluctuation height The standard deviation of the fluctuation height is σ, where

[0024]

[0025] Indicates the highest height value in the vertical direction of the second positioning ball in the xth column and yth row in the X*Y positioning ball array formed by the second positioning ball within a preset time period; Indicates the lowest height value of the second positioning ball in the xth column and yth row in the X*Y positioning ball array formed by the second positioning ball in the vertical direction within a preset time period;

[0026] The data processing and warning module receives the liquid level fluctuation data provided by the second image tracking module. σ, when the liquid level fluctuation data is abnormal, the data processing warning module issues a warning.

BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Figure 1 This is a structural diagram of the intelligent water pump data early warning system.

[0040] Figure 2 Schematic diagram of the floating platform structure.

[0041] Figure 3 This is a top view of the floating platform. DETAILED DESCRIPTION

[0042] For better understanding and implementation, the present invention is described in detail below with reference to the accompanying drawings.

[0043] like Figure 1 As shown, the intelligent water pump data early warning system includes a guide rail 3, a floating platform 4, an image tracking module and a data processing early warning module. The guide rail 3 is detachably arranged on the side wall of the water storage tank 1. A water pump water inlet pipe 51 is arranged in the water storage tank 1. The water pump 5 is connected to the water inlet pipe 51, and the liquid in the water storage tank 1 is extracted through the water inlet pipe 51. The floating platform 4 is slidably and detachably arranged on the guide rail 3. The floating platform 4 floats on the liquid surface of the water storage tank 1. The floating platform 4 is arranged above the water inlet of the water inlet pipe 51. Therefore, when it is necessary to warn the water pump, it is only necessary to install the guide rail and the floating platform in the corresponding water storage tank, and set the image tracking module and the data processing early warning module at the appropriate position. There is no need to make additional modifications to the original water pump, and the intelligent water pump data early warning system is easy to disassemble and assemble.

[0044] It should be noted that Figure 1 It is only a schematic diagram, and the shape of the water storage tank 1 and the location of the water pump 5 and the water inlet pipe 51 can be flexibly set according to actual conditions.

[0045] like Figure 2-3 As shown, the floating platform 4 includes a main frame 40 and a connecting frame 42. One end of the connecting frame 42 is connected to the main frame 40, and the other end of the connecting frame 42 is connected to the guide rail 3; the connecting frame 42 is provided with two groups, and the guide rail 3 is provided with two groups ( Figure 2In order to clearly show the structure of each component, one set of guide rails 3 is omitted; each set of connecting brackets 42 is provided with two horizontal protrusions 421, and the two horizontal protrusions 421 of each set of connecting brackets 42 are arranged on different horizontal planes; the horizontal protrusions 421 are arranged in the guide grooves 31 of the guide rails 3, and the guide grooves 31 are configured to limit the movement of the horizontal protrusions 421 in directions other than the vertical direction.

[0046] By providing two groups of connecting brackets 42 with a total of four horizontal protrusions 421, the movement of the floating platform 4 can be restricted to the vertical direction, thereby avoiding the fluctuation of the liquid in the water storage tank 1 caused by the operation of the water pump 5, which causes the floating platform 4 to deflect. This can make the data collected by the image tracking module more stable and accurate.

[0047] Furthermore, since the fluctuation of the liquid in the water storage tank 1 will cause the floating platform 4 to move up and down frequently, in order to reduce this movement, a motion damping module can be set in the guide groove 31 to provide additional friction for the movement of the horizontal protrusion 421 in the guide groove 31, thereby avoiding frequent ups and downs of the floating platform, thereby further making the data collected by the image tracking module more stable.

[0048] The floating platform 4 further includes a floating ball 41. The floating ball 41 is connected to the main frame 40, and there are four floating balls, which are arranged on the same horizontal plane and float on the liquid surface of the water storage tank 1. The floating balls are used to provide buoyancy for the floating platform.

[0049] The floating platform 4 further includes a positioning frame 43 and a counterweight 44. The positioning frame 43 is connected to the main frame 40, and the counterweight 44 is disposed below the positioning frame 43. The weight of the counterweight 44 is configured so that when the floating platform 4 floats on the surface of the liquid, the positioning frame 43 is half submerged in the liquid in the vertical direction (or 40% to 60% of the vertical height of the positioning frame 43 is submerged).

[0050] The floating platform 4 also includes a first positioning ball 45 and a second positioning ball 431. The first positioning ball 45 and the second positioning ball 431 are made of materials that can be detected by the image tracking module. There are 4 first positioning balls 45, and the first positioning balls 45 are arranged at different positions on the same horizontal plane of the main frame 40. The positioning frame 43 includes a horizontal rod and a vertical rod, and the second positioning ball 431 is slidably arranged on the vertical rod of the positioning frame 43, and the second positioning ball 431 floats on the liquid surface of the water storage tank 1. The second positioning balls 431 form an X*Y array, where X and Y are the total number of rows and columns of the second positioning ball array. Preferably, the second positioning balls 431 form a 3*3 array. Different marks or patterns can be set on each of the first positioning balls 45 and each of the second positioning balls 431, so that the image tracking module can identify and distinguish the first positioning balls 45 and the second positioning balls 431.

[0051] In the water pump data warning, the liquid level data is one of the important monitoring data. Since the first positioning ball 45 is fixedly connected to the floating platform 4, the height value of the first positioning ball 45 in the vertical direction is related to the height of the current liquid level. Therefore, the first positioning ball 45 can be used to obtain the liquid level data.

[0052] The image tracking module includes a first image tracking module 61, and the first image tracking module 61 is arranged on the top or above the wall of the water storage tank 1. The first image tracking module 61 can be a depth camera or a binocular camera. The first image tracking module 61 is used to track the first positioning ball 45 and obtain liquid level change data. Specifically, the positional relationship between the four first positioning balls 45 is known in advance, so the first positioning ball 45 can be tracked by the tracking, alignment and coordinate transformation methods commonly used in the prior art, so as to obtain the real-time position of each first positioning ball 45. Since the first positioning ball 45 is fixedly connected to the floating platform 4, the height value of the first positioning ball 45 in the vertical direction is related to the height of the current liquid level, and the change in the height value of the first positioning ball 45 is the liquid level change.

[0053] The data processing and early warning module receives the liquid level change data provided by the first image tracking module 61. When the liquid level change data is abnormal, the data processing and early warning module issues an early warning. For example, when the liquid level change data within the preset time is less than the first threshold value, it indicates that the water pump has not performed effective pumping operations, and the data processing and early warning module issues an early warning to prompt the staff to check. Alternatively, when the liquid level change data within the preset time is greater than the second threshold value, it indicates that the pumping operation of the water pump has been completed or the current water storage tank liquid level is too low, and the data processing and early warning module issues an early warning to prompt the staff to check.

[0054] Since the position of the positioning ball is related to the liquid surface, the liquid surface data can be obtained by tracking the positioning ball through the image tracking module, which can avoid the influence of water surface reflection in the direct collection of water surface images. The liquid surface data is related to the working condition of the water pump, so the corresponding data warning can be carried out according to the liquid surface data collected by the image tracking module.

[0055] However, in some cases, abnormal operation of the water pump will not be reflected in the liquid level data. For example, when the water pump has uneven pumping in certain fault conditions (i.e., pumping occurs intermittently due to reasons such as blockage of the water inlet pipe and motor failure), or cavitation occurs in the pump, the liquid level data may be normal at this time. Therefore, the liquid level data alone cannot comprehensively warn of water pump abnormalities. The applicant noted that the above situation will cause abnormal fluctuations in the liquid level. Since the second positioning ball array is floating on the liquid surface of the water storage tank 1, the height value of each second positioning ball in the second positioning ball array can reflect the abnormal fluctuation of the liquid level. However, if only the first image tracking module 61 tracks the second positioning ball, the height value of the second positioning ball observed by the first image tracking module 61 is superimposed with the change in the liquid level and the change in the liquid level fluctuation, which will result in the need for additional processing of the height value data observed by the first image tracking module 61, which is not convenient.

[0056] Therefore, preferably, the image tracking module also includes a second image tracking module 62, which is arranged on the main support 40. The second image tracking module 62 can be a depth camera or a binocular camera. The second image tracking module 62 is used to track the second positioning ball 431 and obtain liquid surface fluctuation data. The second positioning ball 431 can be tracked by the tracking, registration and coordinate transformation methods commonly used in the prior art, so as to obtain the real-time position of each second positioning ball 431. Optionally, the positioning frame 43 can also be provided with a pattern, a mark or an additional positioning module that can be tracked by the second image tracking module 62, so as to facilitate the tracking, registration and coordinate transformation of the second positioning ball 431. In order to enable the second image tracking module 62 to better track the second positioning ball 431, the diameter of the vertical rod and / or horizontal rod of the positioning frame 43 is as small as possible while ensuring the structural strength, and / or the positioning frame 43 is made of transparent material. Specifically, each ball of the second positioning ball array can only move in the vertical direction along its corresponding vertical rod, and the second positioning ball array floats on the liquid surface of the water storage tank 1. Therefore, the height of each second positioning ball in the vertical direction is related to the height of the liquid surface where the second positioning ball is located, and the second positioning ball array can reflect the fluctuation of the corresponding liquid surface. At the same time, since the second image tracking module 62 is fixedly arranged on the floating platform, the liquid surface fluctuation data collected by it has offset the influence of the liquid level change, which is convenient for subsequent data processing.

[0057] Specifically, Indicates the highest height value of the second positioning ball in the xth column and yth row in the X*Y array formed by the second positioning ball in the vertical direction within a preset time period; Indicates the lowest vertical height of the second positioning ball in the xth column and yth row in the second positioning ball array within a preset time period. Use the average value of the fluctuating height The standard deviation of the fluctuation height σ is used to measure the liquid level fluctuation data in a preset time period, where

[0058]

[0059] The data processing warning module receives the liquid level fluctuation data provided by the second image tracking module 62 σ, when the liquid level change data is abnormal, the data processing warning module issues a warning. For example, when the liquid level change data is abnormal within the preset time When σ is greater than the third threshold, and / or σ is greater than the fourth threshold, it indicates that the water surface fluctuates greatly, indicating that cavitation may occur, or uneven pumping occurs, and the data processing warning module issues a warning to prompt the staff to check. It is understandable that at this time, the water storage tank 1 should be isolated from the outside world to avoid false warnings caused by the environment.

[0060] Optionally, the intelligent water pump data warning system further includes a light source module, which is used to provide light to the first positioning ball 45 and the second positioning ball 431 so that the first positioning ball 45 and the second positioning ball 431 can be tracked by the image tracking module. The position of the light source module can be flexibly selected according to actual needs.
