Technical Field

[0001] The invention belongs to the technical field of water level detection, and in particular relates to a method and system for adaptively adjusting the installation height of a water gauge. Background Art

[0002] In water conservancy and municipal engineering, the water level value of water level detection is generally composed of the instrument measurement value of the water level measuring instrument and the water level base value. In the prior art, after the water level measuring instrument is installed, a distance measuring instrument (such as a tape measure) is used to manually measure the installation height of the water level measuring instrument, which is then input into the electronic water gauge as the water level base value. The electronic water gauge calculates the water level value in the actual installation environment based on its own measurement value and the manually input water level base value.

[0015] S24: If the judgment result is yes, the installation height value is stored as the water level base value.

[0016] If the judgment result is no, the step S2 further includes:

[0017] S25, the microprocessor sets the measurement mode to the short-distance measurement mode and sets the short-distance calibration value;

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, a first image may be referred to as a second image, and similarly, a second image may be referred to as a first image without departing from the scope of this application. Both the first image and the second image are images, but they are not the same image.

[0036] In the prior art, when commonly used water level measuring instruments are installed and applied in actual projects, the water level base value is usually measured and input manually according to the installation position of the water level measuring instrument. This method has the disadvantages of inconvenient operation and low installation efficiency, and the manual measurement and input process may cause measurement errors due to human errors. Therefore, the present invention intends to use a high-precision laser ranging sensor in the intelligent water gauge, and automatically measure and correct the water level base value according to the changes in the installation position and environment through an adaptive calibration algorithm.

[0037] See also Figure 1 , as a first aspect of the present invention, a method for adaptively adjusting the installation height of a water gauge is disclosed, the method comprising:

[0038] Step S1, install the distance measuring sensor at the bottom of the smart water gauge and connect it to the microprocessor of the smart water gauge; the microprocessor can be an electronic device with computing capability. The structure of the electronic device will be described in detail later and will not be repeated here.

[0039] In step S1, the microprocessor can control the power supply of the laser distance sensor and configure and read the register of the laser distance sensor.

[0040] In step S1, the distance measuring sensor uses a high-precision sensor component with a range of 5-20 cm. The distance measuring sensor uses one of an ultrasonic distance measuring sensor, a laser distance measuring sensor, an infrared distance measuring sensor, and a millimeter wave radar sensor.

[0041] In step S1, when the distance measuring sensor adopts a laser distance measuring sensor, a dustproof glass sheet is arranged at the bottom of the smart water gauge, the dustproof glass sheet seals the laser distance measuring sensor at the bottom of the smart water gauge, and the laser of the laser distance measuring sensor can be emitted through the dustproof glass sheet.

[0042] Step S2, the microprocessor controls the distance measuring sensor to perform multiple measurements, and uses an adaptive calibration algorithm to calculate the installation height value within the installation height range, and uses it as the water level base value.

[0043] The step S2 specifically includes:

[0044] S21, the microprocessor sets the measurement mode to the middle distance measurement mode, and sets the middle distance calibration value;

[0045] S22, the microprocessor controls the distance measuring sensor to perform multiple measurements, and uses an average value filtering algorithm to calculate the measured value to obtain the installation height value;

[0046] S23, comparing the installation height value with the mid-distance calibration value to determine whether the installation height value is within the mid-distance measurement range;

[0047] S24: If the judgment result is yes, the installation height value is stored as the water level base value.

[0048] If the judgment result is no, the step S2 further includes:

[0049] S25, the microprocessor sets the measurement mode to the short-distance measurement mode and sets the short-distance calibration value;

[0050] S26, the microprocessor controls the distance measuring sensor to perform multiple measurements, and uses an average value filtering algorithm to calculate the measured value to obtain the installation height value;

[0051] S27, comparing the installation height value with the short-distance calibration value to determine whether the installation height value is within the short-distance measurement range;

[0052] S28: If the judgment result is yes, the installation height value is stored as the water level base value.

[0053] In this step, when the water level base value is detected, it can be saved in the microprocessor. When the platform queries the water level base value, the intelligent water gauge reports the water level base value.

[0054] If the installation height value is not within the short distance measurement range, it indicates that an error has occurred in the distance measurement.

[0055] In this step, an indicator light, beep, voice prompt or other prompting method can be used to prompt that an error has occurred in the distance measurement. When an error has occurred in the measurement, the water level base value can be modified through the platform, and the smart water gauge can modify and store the water level base value.

[0057] The distance measuring sensor is installed at the bottom of the intelligent water gauge and is connected to the microprocessor of the intelligent water gauge for communication;

[0058] The microprocessor controls the distance measuring sensor to perform multiple measurements and uses an adaptive calibration algorithm to calculate the installation height value within the installation height range and use it as the water level base value.

[0059] The microprocessor can control the power supply of the laser distance sensor. The microprocessor configures and reads the register of the laser distance sensor. The distance sensor adopts a high-precision sensor component with a range covering 5-20cm. The distance sensor adopts one of an ultrasonic distance sensor, a laser distance sensor, an infrared distance sensor, and a millimeter wave radar sensor.
