Description

Technical Field

[0001] This application relates to the technical field of water level measurement, and particularly to a water level measurement device. Background Art

[0002] Water level measurement plays an important role in hydrological monitoring and disaster warning systems. Especially in flood-prone areas and coastal cities, water level changes directly affect multiple fields such as disaster prevention and mitigation, shipping safety, agricultural irrigation, and water resource management. With the increase in climate change and extreme weather events, disasters such as heavy rain and floods occur frequently, posing a serious threat to low-lying areas and urban drainage systems. Therefore, how to achieve accurate water level measurement is crucial for disaster warning and emergency response.

[0003] In related technologies, water level measurement devices mainly include pressure water level gauges, acoustic water level gauges, and radar water level gauges, etc. The pressure water level gauge calculates the water level by measuring the pressure of the water column, and has a relatively simple working principle. However, since the sensor is easily affected by water body corrosion and sediment, measurement errors are likely to occur during long-term use. The acoustic water level gauge measures the water level by emitting and receiving sound waves, has a relatively wide measurement range and strong adaptability, but the equipment cost is high, and it is easily interfered by environmental factors such as water flow and temperature changes. The radar water level gauge uses radar wave reflection to detect water level changes, has the advantage of non-contact, but is greatly affected by external environments such as weather and waves, with unstable accuracy, and the equipment is relatively expensive and the maintenance is also relatively complex.

[0004] Therefore, although the existing water level measurement devices meet the requirements of hydrological monitoring to a certain extent, in practical applications, there are still deficiencies in terms of accuracy, stability, cost, etc. Especially in complex environments, it is often difficult to balance various requirements. Therefore, there is an urgent need for a water level measurement device that can effectively overcome the deficiencies of the existing technologies and achieve more accurate, stable, and low-cost water level measurement.

[0046] The following will describe in detail some embodiments of this application in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0047] Please refer to Figure 1 , Figure 1 which is a schematic diagram of the scenario of the water level measurement device provided for the embodiments of this application. As Figure 1 shown, the water level measurement device provided by this application includes a wave-dissipating component 1, at least two magnetic force detection components 2, and a controller 3. Among them, the wave-dissipating component 1 is vertically arranged in the water area to be measured, and part of it is arranged below the water surface. A magnetic floating object 10 is arranged in the wave-dissipating component 1, and the magnetic floating object 10 floats on the water surface. At least two magnetic force detection components 2 are arranged on the wave-dissipating component 1 at intervals along the axis of the wave-dissipating component 1; the horizontal distance between the magnetic floating object 10 and the outer periphery of the wave-dissipating component 1 is constant, and the direction of the magnetic floating object 10 is constant; the controller 3 is connected to each of the magnetic force detection components 2 and is used to calculate the altitude of the magnetic floating object 10 according to the detection data transmitted by the magnetic force detection components 2; among them, the altitude of the magnetic floating object 10 is used to represent the water level of the water area to be measured.

[0048] It should be understood that the wave-damping component 1 is vertically arranged in the water area to be measured, and part of its structure is below the water surface, thereby reducing the influence of water surface fluctuations on the measurement. The magnetic floating object 10 inside the wave-damping component 1 floats on the water surface and can freely rise and fall vertically with the change of water level, thereby realizing the measurement of water level. The above embodiments can ensure the stability of the magnetic floating object 10 during the measurement process by the wave-damping component 1, thereby improving the water level measurement accuracy.

[0049] Furthermore, the magnetic floating object 10 has a fixed magnetic polarity direction and always maintains a constant horizontal distance from the outer periphery of the wave-damping component 1, thereby ensuring that the magnetic floating object 10 will not drift laterally during the rising and falling process, and further improving the accuracy of water level measurement.

[0050] Exemplarily, the above-mentioned constant horizontal distance between the magnetic floating object 10 and the outer periphery of the wave-damping component 1 can be specifically achieved in the following way: for example, a square through-hole can be dug in the middle of the magnetic floating object 10, and then a square guide tube can be placed in the middle of the wave-damping component 1, and finally the square guide tube can be inserted into the magnetic floating object 10. This embodiment is not limited thereto.

[0051] Exemplarily, at least two magnetic force detection components 2 are distributed at intervals along the axial direction of the wave-damping component 1, and can be used to sense the magnetic field signal of the magnetic floating object 10 and output corresponding detection data. Since the altitude of the magnetic floating object 10 changes with the water level, the magnetic force detection component 2 can determine the real-time height of the magnetic floating object 10 through the magnetic field change, thereby realizing the measurement of water level. Moreover, at least two magnetic force detection components 2 adopt a multi-point detection mechanism, which can avoid single-point measurement errors and improve the reliability of measurement.

[0052] Exemplarily, the controller 3 is respectively connected to each magnetic force detection component 2, thereby being able to receive the detection data transmitted by the magnetic force detection component 2 and calculate the altitude of the magnetic floating object 10 based on this data, and further characterize the water level situation of the water area to be measured.

[0053] This application stabilizes the water surface fluctuations through the wave-damping component 1 to ensure that the magnetic floating object 10 always floats in a fixed direction, thereby improving the stability and accuracy of water level measurement. The magnetic force detection components 2 are distributed at intervals and can accurately sense the altitude of the magnetic floating object 10 to avoid measurement errors caused by water surface fluctuations. The controller 3 calculates the water level in combination with the magnetic force detection data to achieve high-precision measurement, long-term stability and low maintenance cost of water level measurement.

[0054] It should be noted that the present application does not limit the number of at least two magnetic force detection components 2. For example, the number of at least two magnetic force detection components 2 may include 2, 3, 4, etc. It should be understood that the more the number of magnetic force detection components 2, the more measurement data the controller 3 can obtain, and perform multi-point data fusion and error correction, thereby reducing the error caused by local interference and improving the accuracy and stability of water level measurement.

[0055] Optionally, at least two magnetic force detection components 2 include a first magnetic force detection component 20 and a second magnetic force detection component 21, and the first altitude of the first magnetic force detection component 20 is higher than the second altitude of the second magnetic force detection component 21; the controller 3 is further configured to determine a first height difference between the magnetic float 10 and the first magnetic force detection component 20 and a second height difference between the magnetic float 10 and the second magnetic component 21, and calculate the altitude of the magnetic float 10 according to the first height difference, the second height difference, the first altitude and the second altitude.

[0056] Exemplarily, the first magnetic force detection component 20 and the second magnetic force detection component 21 are arranged at intervals along the axial direction of the wave-dissipating component 1, and the first altitude of the first magnetic force detection component 20 is higher than the second altitude of the second magnetic force detection component 21, that is, the first magnetic force detection component 20 is at a higher position and the second magnetic force detection component 21 is at a lower position. The magnetic float 10 has a fixed magnetic polarity direction and moves up and down along the vertical direction as the water level changes. When the magnetic float 10 is located between the first magnetic force detection component 20 and the second magnetic force detection component 21, the two magnetic force detection components 2 can respectively detect its magnetic field signal and calculate its relative height difference.

[0057] Furthermore, the controller 3 can calculate the first height difference between the magnetic float 10 and the first magnetic force detection component 20, and calculate the second height difference between the magnetic float 10 and the second magnetic force detection component 21. Thus, by combining the first height difference, the second height difference, the altitude of the first magnetic force detection component 20 and the altitude of the second magnetic force detection component 21, using interpolation calculation or other mathematical models, the altitude of the magnetic float 10 can be accurately calculated, and then the water level of the measured water area can be characterized. For the sake of avoiding repetition, it will be described in detail later.

[0058] Optionally, the controller 3 is further configured to determine a first height difference between the magnetic float 10 and the first magnetic force detection component 21, including: the controller 3 is further configured to determine a second height difference between the magnetic float 10 and the second magnetic force detection component 21 according to the following formula:

[0059]

[0060] where, Δh iis the second height difference; l is the straight-line distance between the second magnetic force detection component 21 and the magnetic floating object 10; d is the horizontal distance between the magnetic floating object 10 and the outer periphery of the wave-dissipating component 1.

[0061] It should be noted that the above l, that is, the straight-line distance between the second magnetic force detection component 21 and the magnetic floating object 10, can be obtained through the following formula:

[0062]

[0063] where l is the straight-line distance between the second magnetic force detection component 21 and the magnetic floating object 10; f is the detection data transmitted by the second magnetic force detection component 21; n is an exponent related to the type of the second magnetic force detection component 21, etc.

[0064] Similarly, the first height difference Δh i+1 can also be obtained based on the above formula. To avoid repetition, it will not be elaborated here.

[0065] Optionally, the controller 3 is further configured to calculate the altitude of the magnetic floating object 10 according to the first height difference, the second height difference, the first altitude, and the second altitude, including: the controller 3 is further configured to determine the positional relationship of the magnetic floating object 10 relative to the first magnetic force detection component 20 and the second magnetic force detection component 21 according to the first height difference, the second height difference, the first altitude, and the second altitude, and calculate the first initial altitude of the magnetic floating object 10 based on the first height difference and the first altitude, and calculate the second initial altitude of the magnetic floating object 10 through the second height difference and the second altitude, and obtain the altitude of the magnetic floating object 10 according to the first initial altitude and the second initial altitude.

[0066] Among them, the first initial altitude is the altitude of the magnetic floating object 10 calculated based on the first magnetic force detection component 20; the second initial altitude is the altitude of the magnetic floating object 10 calculated based on the second magnetic force detection component 21.

[0067] Exemplarily, based on the known altitudes of the two magnetic force detection components 2 and measuring the height differences of the magnetic floating object 10 relative to them, the actual altitude of the magnetic floating object 10 can be calculated. First, the controller 3 can obtain the altitude of the first magnetic force detection component 20 and calculate the first initial altitude in combination with the measured first height difference of the magnetic floating object 10 relative to the first magnetic force detection component 20. Similarly, the controller 3 can calculate the second initial altitude using the data of the second magnetic force detection component 21.

[0068] Further, since the position of the magnetic float 10 may be affected by environmental factors, there may be errors in the first initial altitude and the second initial altitude. Therefore, the controller 3 can combine the positional relationship of the magnetic float 10 relative to the two magnetic force detection components, perform weighted averaging or error correction on the two, obtain a more accurate final altitude, and thereby improve the accuracy of water level measurement.

[0069] Optionally, the controller 3 is further configured to determine the positional relationship of the magnetic float 10 relative to the first magnetic force detection component 20 and the second magnetic force detection component 21 according to the first height difference, the second height difference, the first altitude, and the second altitude, including: the controller 3 is further configured to add the first height difference and the second height difference to obtain a sum value, and subtract the first altitude and the second altitude to obtain a difference value; if the difference between the sum value and the difference value is less than a preset difference value, it is determined that the magnetic float 10 is between the first magnetic force detection component 20 and the second magnetic force detection component 21; the controller 3 is further configured to determine that the magnetic float 10 is below the second magnetic force detection component 21 when the second height difference is greater than the difference value and the first height difference respectively; the controller 3 is further configured to determine that the magnetic float 10 is above the first magnetic force detection component 20 when the first height difference is greater than the difference value and the second height difference respectively.

[0070] It should be noted that the present application does not limit the above preset threshold values. For example, the preset threshold values are 0.1 m, 0.2 m, 0.5 m, etc.

[0071] Among them, the first altitude can be expressed as h i+1 ; the second altitude can be expressed as h i ; the first height difference can be expressed as Δh i+1 ; the first height difference can be expressed as Δh i . Since the first altitude of the first magnetic force detection component 20 is higher than the second altitude of the second magnetic force detection component 21, so h i+1 >h i .

[0072] Exemplarily, if the difference between the above sum value and the difference value is less than the preset difference value, it means that the sum value of the first height difference and the second height difference is approximately equal to the difference between the first altitude and the second altitude, that is, it can be expressed as Δh i +Δh i+1 ≈h i+1 -h i . Thus, it can be determined that the magnetic float 10 is between the first magnetic force detection component 20 and the second magnetic force detection component 21. Further, if the second height difference is greater than the difference value and the first height difference respectively, it can be expressed as Δh i+1 >h i+1 -h i and Δh i+1 >Δhi Thus, it can be determined that the magnetic floating object 10 is below the second magnetic force detection component 21. In addition, if the first height difference is greater than the difference value and the second height difference respectively, it can be expressed as Δh i >h i+1 -h i and Δh i >Δh i+1 。Thus, it can be determined that the magnetic floating object 10 is above the first magnetic force detection component 20.

[0073] In the above embodiment, by calculating the sum value of the first height difference and the second height difference and comparing it with the difference between the first altitude and the second altitude, it is possible to quickly determine whether the magnetic floating object 10 is located between the two magnetic force detection components 2. And when the height difference meets specific conditions, it can be further determined that the magnetic floating object 10 is above or below a certain magnetic force detection component 2, thereby providing more accurate position information and further improving the accuracy of water level measurement.

[0074] Optionally, the controller 3 calculates the first initial altitude of the magnetic floating object 10 based on the position relationship through the first height difference and the first altitude, including: if the position relationship is that the magnetic floating object 10 is between the first magnetic force detection component 20 and the second magnetic force detection component 21 or below the second magnetic force detection component 21, it is determined that the first initial altitude is the difference between the first altitude and the first height difference; if the position relationship is that the magnetic floating object 10 is above the first magnetic force detection component 20, it is determined that the first initial altitude is the sum of the first altitude and the first height difference.

[0075] Exemplarily, if the position relationship is that the magnetic floating object 10 is between the first magnetic force detection component 20 and the second magnetic force detection component 21 or below the second magnetic force detection component 21, the first initial altitude h i ′ +1 can be expressed as: h i i +1 =h i+1 -Δh i+1 ; if the position relationship is that the magnetic floating object 10 is above the first magnetic force detection component 20, the first initial altitude h i i +1 can be expressed as: h i i +1 =h i+1 +Δh i+1 。

[0076] Optionally, the controller 3 calculates the second initial altitude of the magnetic floating object 10 based on the positional relationship through the second height difference and the second altitude, including: if the positional relationship is that the magnetic floating object 10 is between the first magnetic force detection component 20 and the second magnetic force detection component 21 or above the first magnetic force detection component 20, it is determined that the second initial altitude is the sum of the second altitude and the second height difference; if the positional relationship is that the magnetic floating object 10 is below the second magnetic force detection component 21, it is determined that the first initial altitude is the difference between the second altitude and the second height difference.

[0077] Exemplarily, if the positional relationship is that the magnetic floating object 10 is between the first magnetic force detection component 20 and the second magnetic force detection component 21 or above the first magnetic force detection component 20, the second initial altitude h i ′ can be expressed as: h i ′ = h i +Δh i ; if the positional relationship is that the magnetic floating object 10 is below the second magnetic force detection component 21, the second initial altitude h i ′ can be expressed as: h ′ ′ = h i -Δh i .

[0078] Optionally, the controller 3 obtains the altitude of the magnetic floating object 10 based on the first initial altitude and the second initial altitude, including: the controller 3 performs an averaging operation on the first initial altitude and the second initial altitude to obtain the altitude of the magnetic floating object 10.

[0079] It should be understood that due to the magnetic field environment, sensor accuracy, and external interference, deviations may occur at a single measurement point. Therefore, directly using the measurement data transmitted by a certain magnetic force detection component 2 may introduce errors. Using the average value of the two magnetic force detection components 2 can balance the deviations and make the final calculation result closer to the true altitude. In addition, this method does not require an additional complex error correction algorithm and can improve the measurement accuracy only through simple mathematical operations, thereby reducing the calculation burden and achieving a more efficient water level measurement.

[0080] Please continue to refer to Figure 2 , Figure 2 which is the structural schematic diagram of the water level measurement device provided by the embodiment of the present application. As Figure 2As shown, the water level measuring device further includes: a battery 4, at least two magnetic control switches 5, and a water level display component 6. Among them, at least two magnetic control switches 5 are electrically connected to the battery, and each magnetic control switch 5 is electrically connected to each magnetic force detection component 2 correspondingly. When the detection data transmitted by the magnetic force detection component 2 is higher than the preset threshold, the corresponding magnetic control switch 5 is in the on state; the water level display component 6 is electrically connected to at least two magnetic control switches 5, and the water level display component 6 is used to display the water level of the corresponding magnetic force detection component 2 when the magnetic control switch 5 is in the on state.

[0081] It should be noted that the present application does not limit the preset threshold. For example, the preset threshold can be 5m, 6m, 7m, etc., and can be specifically set according to user requirements.

[0082] Exemplarily, the water level measuring device realizes real-time monitoring and display of the water level through the coordinated work of the magnetic force detection component 2, the magnetic control switch 5, and the water level display component 6. First, the magnetic force detection component 2 is used to detect the water level height and transmit the detection data to the corresponding magnetic control switch 5. When the detection data is higher than the preset threshold, it indicates that the water level has reached or exceeded a certain set height. At this time, the corresponding magnetic control switch is turned on, allowing current to pass through. The water level display component 6 is connected to the magnetic control switch 5. When the magnetic control switch 5 is closed, the water level display component 6 will display the water level state at the position of the corresponding magnetic force detection component 2. Through the configuration of at least two magnetic control switches 5, the water level display component 6 can hierarchically indicate the states of different water levels, improving the accuracy and reliability of water level measurement. At the same time, since the magnetic control switch 5 is only turned on under specific conditions, it helps to reduce energy consumption and make water level measurement more energy-efficient and efficient.

[0083] Optionally, the water level display component 6 further includes at least two light-emitting sensors 60. The at least two light-emitting sensors 60 are spaced apart on the water level scale of the water level display component 6 and are electrically connected to the at least two magnetic control switches 5 correspondingly, and are used to emit light on the corresponding water level scale when the magnetic control switch 5 is in the on state.

[0084] Exemplarily, through the cooperation of the light-emitting sensor 60 and the magnetic control switch 5, the water level display component 6 can realize visual display of the water level. The at least two light-emitting sensors 60 are evenly spaced on the water level scale of the water level display component 6 and are respectively electrically connected to the corresponding magnetic control switches 5. When the water level rises to the height of a certain magnetic force detection component 2, making the detection data transmitted by it higher than the preset threshold, the corresponding magnetic control switch 5 is turned on, and current passes through, activating the corresponding light-emitting sensor 60 to emit light on the water level scale, thereby intuitively indicating the current water level position. Thus, it can not only provide multi-level water level indication, improving the intuitiveness and accuracy of measurement, but also make the water level measurement more energy-efficient and highly reliable.
