It should be noted that the terms "first," "second," and the like are used merely to distinguish one description from another, and are not intended to indicate or imply relative importance.

The applicant finds that the calibration of the lysimeter at present is usually to calibrate a weight sensor of the lysimeter under laboratory conditions, and the problems that the detection is inaccurate after the lysimeter is installed in a natural environment after the existing calibrated lysimeter is installed due to the fact that influences of natural factors under field conditions and large-scale weight changes (precipitation, water replenishing and leakage) of the lysimeter with a water replenishing device in the operation process are not considered.

In view of the above problems, the applicant of the present application has conducted long-term research and research to propose the following embodiments to solve the above problems. The embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1 and fig. 2, an embodiment of the present application provides a detection management apparatus 10, which can be used to calibrate a lysimeter 20, so as to improve the accuracy and reliability of detection of the lysimeter 20. The lysimeter 20 is typically installed outdoors or in a field environment. The detection management device 10 can be in communication connection with the lysimeter 20 and is used for acquiring data such as weight, water level and the like collected by the lysimeter 20. The detection management device 10 comprises a storage module 12 and a processing module 11 coupled to each other, wherein the storage module 12 stores a computer program, and when the computer program is executed by the processing module 11, the detection management device 10 can execute each step of the management method of the lysimeter 20 described below.

The detection management apparatus 10 may be, but is not limited to, a Personal Computer (PC), a server, or the like.

In the present embodiment, the detection management device 10 may further include other modules, for example, a communication module for establishing a communication connection with the lysimeter 20. The processing module 11, the communication module, the storage module 12 and the elements of the lysimeter detection management device 100 are electrically connected directly or indirectly to realize data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines.

Referring to fig. 2, in the present embodiment, the lysimeter 20 may include a cylinder 21, a first weight detecting module 22, and a water level detecting module 23. Of course, the lysimeter 20 may also include other structural modules, for example, the lysimeter 20 may also include a leakage container 24, a second weight detecting module 25, a water replenishing device 26, a water level pipe 27, a filter layer 28, and the like.

The bottom in the barrel 21 of the lysimeter 20 is provided with a filter layer 28, and a water inlet pipe and a water outlet pipe are arranged at the bottom of the barrel 21. The water inlet pipe is used for replenishing water to the soil in the cylinder 21, the water outlet pipe is used for discharging leakage liquid of the soil, and the water inlet pipe and the water outlet pipe can be the same water pipe (namely, water discharging and water replenishing are separately performed, water is not replenished during leakage water discharging, and water is not discharged during water replenishing) or different water pipes.

When the lysimeter 20 is used, sand or the like having different particle diameters may be filled in the filter layer 28 in the cylinder 21. Generally, the soil filled in the cylinder 21 is an undisturbed soil column to simulate a soil layer in a natural environment. The bottom outside the cylinder 21 is provided with a first weight detection module 22 for detecting the total weight of the cylinder 21. The water inlet of the water supplementing device 26 is communicated with the water inlet pipe, and water can be supplemented to the soil filling of the barrel 21 through the water pump according to actual requirements. The seepage receptacle 24 communicates with a drain for collecting seepage from the soil. Wherein, in the same vertical direction, the highest position of the leakage container 24 is lower than the lowest position of the cylinder 21, so that the leakage liquid in the cylinder 21 can flow into the leakage container 24 under the action of gravity. The second weight detecting module 25 is disposed at the bottom of the leakage container 24 for detecting the total weight of the leakage container 24. The water level pipe 27 and the drum 21 may be communicated through a pipe, and the water level pipe 27 and the drum 21 may form a communicator for visually showing the water level in the drum 21. The water level pipe 27, the leakage container 24, and the cylinder 21 may be connected by a three-way valve. The water level detection module 23 may be provided in the drum 21 or on the water level pipe 27 for detecting the water level in the drum 21. When the water level pipe 27 is used to detect the water level of the cartridge 21, the passage of the three-way valve to the leak container 24 is normally in a closed state.

The detection management device 10 may be electrically connected to the first weight detection module 22, the water level detection module 23, and the second weight detection module 25 of the lysimeter 20, may acquire data collected by the first weight detection module 22, the water level detection module 23, and the second weight detection module 25, and then correct the first weight detection module 22, the water level detection module 23, and the second weight detection module 25 by using a lysimeter detection management method described below, so as to improve accuracy and validity of the data collected by the first weight detection module 22, the water level detection module 23, and the second weight detection module 25.

Referring to fig. 3, an embodiment of the present application further provides a method for detecting and managing a lysimeter, which can be applied to the detection and management device 10, and the detection and management device 10 executes or implements the steps of the method. The method may comprise the steps of:

step S210, placing a first type of reference weight with a first designated weight on the lysimeter at intervals of a first preset time length;

step S220, acquiring first weight change data obtained by detecting the weight of the lysimeter by the first weight detection module N times within each first preset time, where the first weight change data is a variation of the weight data sensed by the first weight detection module from a start time point to a detection time point of the first preset time, and N is an integer greater than 0;

step S230, acquiring a plurality of actual water levels of the lysimeter and sensing water levels respectively obtained by the lysimeter at the actual water levels through the water level detection module;

step S240, when a first relative difference between the first weight change data and the first designated weight is greater than or equal to a first preset weight threshold, correcting the first weight detection module according to a corresponding relationship between the first weight change data and the first designated weight, so that the corrected first relative difference is smaller than the first preset weight threshold;

step S250, when the second relative difference between the sensed water level and the actual water level is greater than or equal to a preset water level threshold, correcting the water level detection module according to the corresponding relationship between the sensed water level and the actual water level, so that the corrected second relative difference is smaller than the preset water level threshold.

In this embodiment, through first weight detection module, the water level detection module to evaporating and oozing the appearance and rectify, realize the demarcation to evaporating and oozing the appearance, can improve accuracy and the validity that evaporates and ooze the appearance and detect after the correction.

The individual steps in the process are explained in detail below, as follows:

in step S210, a first type of reference weight with a first designated weight may be placed on the lysimeter at intervals of a first preset duration by the mechanical arm, or a first type of reference weight with a first designated weight may be placed on the lysimeter at intervals of a first preset duration in a manual operation manner. Understandably, the manner of placing the first type of reference weight can be set according to practical situations, and is not particularly limited herein.

The first preset time period may be set according to actual conditions, and may be a short time period such as 3 minutes, 5 minutes, and the like. The first designated weight can be set according to actual conditions, the weight of the first type of reference weight placed on the lysimeter at each time can be different, and the times of placing the weight on the lysimeter can be set according to actual conditions. For example, in step S210, the first type reference weight may be placed on the cylinder of the lysimeter 7 times, each time the interval time is three minutes, and the weight of the first type reference weight placed on each time may be gradually increased. For example, the first type of reference weight may be placed in a weight range of 1kg, 3kg, 5kg, 10kg, 15kg, 25kg, 45kg, respectively.

The first weight detection module is used for detecting the total weight of the cylinder of the lysimeter, and when a first type of reference weight is placed on the lysimeter each time, the first type of reference weight can be understood to be placed on the cylinder of the lysimeter. When the first type of reference weight is placed, the weight of the cylinder detected by the first weight detection module changes. The first type of reference weight is a weight with a specified weight after weight detection, for example, the first type of reference weight may be a weight with a specified weight.

In step S220, the detection management device may be used as a data acquisition device to acquire the weight data or weight change data detected by the first weight detection module from the lysimeter. The detection management apparatus may continuously acquire weight data or weight change data detected by the first weight detection module N times when the data detected by the first weight detection module is relatively stable each time the first type of reference weight is placed. N may be determined according to actual conditions, and may be, for example, 3 times, 4 times, or the like. And in the first preset time, after a few seconds or a few tens of seconds after the first type of reference weight is placed, the data detected by the first weight detection module is considered to be relatively stable data. The first weight change data can be understood as the difference value of the weight data respectively detected by the first weight detection module at the current detection time and at the starting time of the first preset time length and when the first type of reference weight is not placed. That is, the first weight change data is a change amount of the weight data sensed by the first weight detecting module from a starting time point to a detecting time point of the first preset time period, and is the detected weight data of the first type of reference weight.

Step S220 may include: within each first preset time, acquiring N times of weight variation of the lysimeter detected by the first weight detection module; and taking the average value of the weight change amount of the N times as the first weight change data.

Understandably, N times may be multiple times. In each first preset time, the weight variation of the lysimeter is detected by the first weight detection module for N times, and then the average value is calculated and used as the variation data of the weight detected by the first weight detection module after the first type of reference weight is placed for one time. Based on this, be favorable to improving the accuracy and the validity of the weight variation that detects, avoid because of the occasional error that single detection leads to is big, and influence the validity of the data that obtains.

As an optional implementation manner, the first weight detection module includes a plurality of weight sensors, which are disposed at the bottom of the barrel of the lysimeter and are used for detecting the weight of the lysimeter; step S220 may include:

In this embodiment, the lysimeter may be a large lysimeter. For example, after the barrel of the lysimeter is filled with the filter layer, water and the soil column, the total weight of the barrel can be about 40 tons.

The single wide-range weight sensor is not easy to directly detect the weight of the cylinder. Therefore, a plurality of weight sensors may be provided at the bottom of the cylinder. The number of the weight sensors included in the first weight detection module may be set according to actual conditions, and may be, for example, 3, 4, or the like. Each weight sensor can be arranged on the same horizontal plane, and supports the barrel together to share the weight of the barrel and detect the weight of the barrel. Based on this, the total weight of barrel is the sum of the weight data that every weight sensor detected to can reduce the biggest measuring range of single weight sensor, be favorable to the weight detection of large-scale lysimeter barrel.

In step S230, when an actual water level is obtained, a sensed water level corresponding to the actual water level is obtained by the water level monitoring module. Understandably, the actual water level can be water level data obtained by staff detecting liquid in the water level pipe as shown in fig. 2 through a measuring scale or other water level monitors, and the water level data is the actual water level. The sensing water level is a water level at which the water level detection module detects liquid in the water level pipe.

The plurality of actual water levels may be obtained at different points in time. Step S230 may be understood as supplying water to the lysimeter every preset time interval (e.g., 5 minutes, 10 minutes), and acquiring a sensed water level corresponding to a first water level by the water level monitoring module when the actual water level of the cylinder is maintained at the first water level; and then, water is continuously supplemented, and when the actual water level of the cylinder body is maintained at the second water level, a sensing water level corresponding to the second water level is obtained through the water level monitoring module. Through moisturizing many times, alright in order to obtain a plurality of actual water levels and the sensing water level that corresponds with actual water level respectively.

In step S240, the absolute value of the difference between the first weight variation data and the first designated weight is the first relative difference. The first preset weight threshold is a threshold used for measuring whether the accuracy of the first weight detection module is reliable, when the first relative difference is greater than or equal to the first preset weight threshold, it indicates that the difference between the weight detected by the first weight detection module and the actual weight is large, at this time, the detected weight data is generally invalid data, and at the same time, it indicates that the detection of the first weight detection module is inaccurate and needs to be corrected. When the first relative difference is smaller than the first preset weight threshold, it indicates that the difference between the weight detected by the first weight detection module and the actual weight is small, and at this time, the detected weight data is usually valid data, and at this time, no correction is needed.

For example, referring to fig. 4, when the first weight detecting module is calibrated, a curve fitting may be performed according to the obtained actual weight (first designated weight) of the first type of reference weight and the first weight change data each time the first type of reference weight is placed. For example, in fig. 4, the abscissa x represents the weight (kg) increased/decreased by the weight, and the ordinate represents the converted weight (kg) corresponding to the lysimeter (cylinder), and the correspondence between the actual weight (first designated weight) and the first weight change data, that is, the correspondence between the actual weight (first designated weight) and the first weight change data, can be obtained by curve fittingThe correlation coefficient R between x and y is 1.037x-0.222²0.9995, the correlation coefficient is the ratio of the sum of the squares of the regression to the sum of the squares of the total dispersion, i.e. R²The calculation is well known to those skilled in the art, and will not be described herein. The closer the correlation coefficient is to 1, the closer the first weight change data is to the weight of the added/removed weight, i.e. the closer the actual weight is to the measured weight, the higher the accuracy of the measurement. Assuming that the difference between the correlation coefficient and 1 is less than 0.001, which indicates that the detection accuracy of the first weight detection module meets the requirement (the first preset weight threshold is the weight when the difference between the correlation coefficient and 1 is 0.001), the first weight detection module corresponding to fig. 2 does not need to be corrected.

Of course, in other embodiments, the correspondence between the actual weight and the first weight change data may be different from that shown in fig. 4.

In this embodiment, the first weight detecting module may be corrected through the corresponding relationship, so that a first relative difference between the first weight change data re-collected by the corrected first weight detecting module and the first designated weight is smaller than a first preset weight threshold.

In step S250, the preset water level threshold is a threshold for determining whether the accuracy detected by the water level detection module meets the standard. When the second relative difference value between the sensed water level and the actual water level is greater than or equal to the preset water level threshold value, the accuracy of the water level detection module does not reach the standard, and correction is needed; when the second relative difference value of the sensed water level and the actual water level is smaller than the preset water level threshold, the detection precision of the water level detection module is qualified, and correction is not needed. When correcting the water level detection module, the water level detection module can be corrected through the corresponding relation between the actual water level and the sensing water level. The method for correcting the water level detection module by using the actual water level and the sensed water level is similar to the method for correcting the first weight detection module, and is not repeated here.

In this embodiment, the lysimeter may further include a water replenishing device for replenishing water to the barrel of the lysimeter. The method can also comprise the step of calibrating the first weight detection module in the water replenishing process by combining the water replenishing device. For example, the method further comprises:

In the above embodiment, when the cylinder is filled with water, the connection pipeline between the cylinder and the leakage container is in a closed state, so that the water supplement in the cylinder is prevented from leaking to the leakage container to affect the water supplement calibration. The designated water level can be determined according to actual conditions, and is generally higher than the current water level of the barrel. And the water level of the cylinder is adjusted by the water supplementing device within the maximum water supplementing range of the lysimeter. For example, during the period that the water replenishing device adjusts the water level of the cylinder from 1500mm to 2500mm (the bottom surface of the cylinder is taken as a water level zero point), the water replenishing device can detect and record the water replenishing amount (namely, the second water replenishing amount) of the water replenishing device in the water level rising process, and the first weight detecting module detects and records the change of the total weight of the cylinder (namely, the first water replenishing amount). The calibrated water supplementing device can accurately detect the water supplementing amount of the water supplementing device for supplementing water to the barrel, and the water supplementing amount is used as the actual water supplementing amount of the water supplementing device for supplementing water to the barrel.

After the first water supplement amount and the second water supplement amount are obtained, the first water supplement amount and the second water supplement amount can be subjected to linear fitting and analysis, and then the first weight detection module is corrected. For example, the first weight detection module is corrected according to the difference between the first water supplement amount and the second water supplement amount, so that the difference between the weight change amount of the cylinder and the second water supplement amount during water injection detected by the corrected first weight detection module is smaller than a set threshold, which can be determined according to actual conditions, and is not limited specifically herein.

As an optional implementation, the lysimeter further comprises a second weight detection module for detecting the weight of a leaking container in the lysimeter, and the method may further comprise:

In the present embodiment, M may be determined according to actual conditions. For example, M may be 3, 4, etc. times. The second weight change data is calculated in a manner similar to that of the first weight change data, and is an average of the weight change amounts acquired M times within a second preset time period.

The second preset time period can be set according to actual conditions, and can be 3 minutes, 5 minutes and the like. The second designated weight is typically a reference weight of lesser weight. The weight of the reference weight placed each time may not be the same. For example, a reference weight may be placed 6 times to the leak container. The weight of the second type of reference weight placed against the leak container at a time may be 5g, 10g, 20g, 50g, 100g, 200g, respectively. The second reference weight is similar to the first reference weight and is a measured reference weight of a given weight, for example a weight.

Understandably, the way of placing the second reference weight on the leakage container is similar to the way of placing the first reference weight, and the way of detecting and correcting the second weight detection module is similar to the way of detecting and correcting the first weight detection module, and the description is omitted here. By correcting the second weight detection module, the accuracy and the effectiveness of the detection of the second weight detection module can be improved.

In this embodiment, after the first weight detection module, the second weight detection module, and the water level detection module are calibrated, the calibrated first weight detection module, the calibrated second weight detection module, and the calibrated water level detection module may be detected until differences between data detected by the calibrated first weight detection module, the calibrated second weight detection module, and the calibrated water level detection module and a threshold are within corresponding ranges, so as to calibrate the lysimeter.

As an optional implementation, the method may further include:

In this embodiment, the passage of the three-way valve to the percolating container is in an open state when P filling tasks are performed. That is, during the water injection process, some of the liquid in the cartridge may leak into the leak container. The water replenishing device can be a peristaltic pump. After the preliminary calibration of the first weight detection module, the second weight detection module and the water level detection module is finished. The peristaltic pump can carry out the water injection to the barrel according to user's settlement water level to make the water level of barrel reach and set for the water level, and detect the moisturizing volume/the water injection volume of taking notes peristaltic pump during the water injection, with as the third moisturizing volume. The water level of the barrel is supplemented to the corresponding set water level through the peristaltic pump for one water injection task, the set water level of each water injection task is usually different, and the set water level can be set according to actual conditions. And then, analyzing and comparing the weight change data of the cylinder body detected by the first weight detection module and the third water supplement amount so as to correct the first weight detection module again and realize the linkage calibration of water supplement-leakage-weight.

P may be determined according to actual conditions, and may be 1, 2, 3, 4, or the like, for example. The water replenishing device can replenish water to the barrel under the control of the detection and management equipment. The water replenishing device comprises a water pump (such as a peristaltic pump) and is used for replenishing water to the cylinder body through the water pump.

As an optional implementation, the method may further include: and when the weight of the leakage liquid in the leakage container reaches a third preset weight threshold value, discharging the leakage liquid in the leakage container.

In this embodiment, the third preset weight threshold may be set according to actual conditions, and is generally a weight of the leakage liquid when the leakage bottle is filled with the leakage liquid. For example, if the weight of the leaking liquid when the leaking bottle is filled with leaking liquid is 0.5 kg, the third predetermined weight threshold may be a value close to 0.5 kg, for example 0.4 kg. The bottom of the leakage container can be provided with an electromagnetic valve, and when the weight of the leakage container reaches a third preset weight threshold value, the detection management equipment can control the electromagnetic valve to be opened so as to discharge leakage liquid stored in the leakage container.

Understandably, the capacity of the leakage container is usually limited, and the leakage container is controlled to discharge the leakage liquid by utilizing the weight of the leakage liquid in the leakage container, so that the leakage liquid in the leakage container is prevented from being too much and being incapable of storing the leakage liquid of the lysimeter to influence the leakage of the lysimeter.

In order to facilitate understanding of the calibration process of the lysimeter, the following will illustrate the steps in the lysimeter detection and management method, as follows:

calibration of the first weight detection module: setting 8 weight gradients (corresponding to actual water depth mm): 0kg (0mm), 1kg (0.25mm), 3kg (0.75mm), 5kg (1.25mm), 10kg (2.5mm), 15kg (3.75mm), 25kg (6.25mm), 45kg (11.23 mm); the method comprises the steps of sequentially adding weights of 1kg, 3kg, 5kg, 10kg, 15kg, 25kg and 45kg on the soil surface of a barrel of the lysimeter from small to large, wherein the placement interval of each weight is 3min, reading 6 values at the head of a collector after data are stabilized, obtaining the slope, intercept and correlation coefficient of the weight by fitting a straight line with the actual weight value after averaging to correct the weight sensor, and writing the slope and intercept of each weight into a program of a data collector corresponding to the slope and intercept of the weight sensor to correct the weight sensor (a first weight detection module) after calibration is completed so that the weight sensor can reflect the actual weight to the maximum extent. Namely, the respective linear relations of the weight sensors can reflect the actual weight of the lysimeter.

Verifying the calibrated first weight detection module in field operation: setting 10 weight (corresponding to water depth mm) gradients: 0g (0mm), 200g (0.05mm), 500g (0.125mm), 1kg (0.25mm), 2kg (0.5mm), 5kg (1.25mm), 10kg (2.5mm), 20kg (5mm), 40kg (10mm), 100kg (25mm), the linear relationship of the weight sensor calibration was first written into the data acquisition program and then verified by adding/removing weights on the surface of the lysimeter cylinder. Two weight increasing/removing modes are adopted, wherein weights with known weight are firstly increased from small to large and removed from large to small on the surface of a cylinder body of the lysimeter (mode one), and the weights are sequentially +200g (0.05mm), +500g (0.125mm), +1kg (0.25mm), +2kg (0.5mm), +5kg (1.25mm), +10kg (2.5mm), +20kg (5mm), +40kg (10mm), +100kg (25mm), -40kg (10mm), -20kg (5mm), -10kg (2.5mm), -5kg (1.25mm), -2kg (0.5mm), -1kg (0.25mm), -500g (0.125mm), -200g (0.05 mm). Then the weights are increased from large to small and removed from small to large (mode two), and the weights are sequentially +100kg (25mm), +40kg (10mm), +20kg (5mm), +10kg (2mm), +5kg (1.25mm), +2kg (0.5mm), +1kg (0.25mm), +500g (0.125mm), +200g (0.05mm), +500g (0.125mm), -1kg (0.25mm), -2kg (0.5mm), -5kg (1.25mm), -10kg (2.5mm), -20kg (5mm), -40kg (10mm), -100kg (25 mm). The time interval of placing and removing each weight is 3min, 3 pieces of data (1 piece of data is collected in every 1 min) of each weight within 3min after the data are stable are taken for average processing, and the obtained data are sequentially subjected to subtraction to obtain the weight change data of the lysimeter. The accuracy of the weight change of the lysimeter under the field operation condition is verified by analyzing the linear relation between the weight of the weight and the measured value of the lysimeter. And if the first relative difference between the first weight change data detected by the weight sensor and the first designated weight is greater than or equal to the first preset weight threshold, correcting the weight sensor again until the first relative difference between the first weight change data detected by the corrected weight sensor and the first designated weight is less than the first preset weight threshold.

Groundwater replenishment, calibration of a water level detection module: water level gauge (water level detection module) calibration: set 4 water level gradients: -440mm, -965mm, -1295mm, -1785 mm. Firstly, closing a corresponding valve to cut off water flow from entering a cylinder body, then opening a valve between a water supplementing device and a water level pipe, adding a set water level gradient, such as-440 mm, into the water level pipe, after a water level meter displays that the water level is stable, automatically recording the water level height of the water level pipe by a detection management device, and simultaneously measuring the actual water level height in the water level pipe by a measuring tape or other calibrated water level detectors; the same operation is carried out to measure other gradient water levels in turn, and after all gradient measurements are finished, the slope and the correlation coefficient (R) between the actual water level and the water level displayed by the water level meter are obtained by fitting the linear regression relationship between the measured actual water level and the sensing water level of the water level meter²) After the water level meter is calibrated, the respective calibrated slopes are written into a program of the water level meter data acquisition unit correspondingly to adjust the deviation of the water level meter, namely the requirement of the accuracy of the water level meter is met. The calibration process of the water level gauge is similar to that of the weight sensor.

Calibration during water replenishing: the weight variation of the detection cylinder body of the first weight detection module under the actual water replenishing condition of the lysimeter is verified by adjusting the height of the underground water level. Firstly, opening a corresponding valve to enable a peristaltic pump to convey water to a cylinder body (during water replenishing calibration, a pipeline leading to a leakage container is in a closed state), then adjusting the underground water level of the cylinder body from-2500 mm to-1500 mm (with the ground as a zero point), and enabling the water replenishing height to be 1000 mm; the lysimeter automatically records the water replenishing height in the water level rising process and the change of the total weight of the barrel detected by the first weight detection module, carries out data sorting and analysis after the water level rises to-1500 mm and is stable, and converts the weight change of the barrel detected by the first weight detection module in the water level rising process into the measured water replenishing amount (namely the first water replenishing amount). The water replenishing amount (namely the second water replenishing amount) of the peristaltic pump is obtained by detecting and recording the peristaltic pump in the water replenishing period and can be used as the actual water replenishing amount. And then carrying out linear fitting analysis on the measured water supplement amount and the actual water supplement amount so as to correct the first weight detection module according to the difference value of the measured water supplement amount and the actual water supplement amount. And if the difference value between the measured water supplement amount and the actual water supplement amount is larger than or equal to the corresponding set threshold value, calibrating the first weight detection module again until the difference value between the measured water supplement amount and the actual water supplement amount is smaller than the preset threshold value.

And calibrating a second weight detection module: set 6 weight gradients: 5g, 10g, 20g, 50g, 100g and 200g, and calibrating the second weight detection module by adding weights (second type of reference weights) with different sizes above a leakage bottle (referring to a leakage container) in sequence to correct the deviation between the displayed value and the actual value. The weights are sequentially increased from small to large, the weight is increased each time, the real weight of the weight is recorded, the measured value of the weight is read on a data collector, each weight is placed for 3 times, 3 numerical values are read, after all weight measurements are completed, the display value of the second weight detection module and the corresponding weight (namely the actual value) are subjected to fitting linear regression to obtain the slope and the correlation coefficient, namely the deviation between the display value and the actual value is analyzed, and finally the slope of each second weight detection module is written into a corresponding program to adjust the accuracy of the second weight detection module, so that the second weight detection module is corrected.

Water supplement-leakage-weight linkage calibration:

first, the ground water level is set: 2 water level change intervals are set: -1500mm to-2500 mm and-2500 mm to-1500 mm; firstly, setting the underground water level to be 2500mm below zero, adjusting the water level to 1500mm below zero after the water level is stable (the error is +/-0.1 mm), automatically recording the water supplementing height value by a water level meter through an evapotranspiration instrument in the underground water supplementing process, and recording the weight change value of the cylinder through a first weight detection module; and when the water level rises to minus 1500mm (+ -0.1 mm) and is stabilized, the water level is reduced to minus 2500mm, the leakage container starts to work in the process of reducing the water level, the first weight detection module and the second weight detection module automatically record the leakage amount in the process of reducing the water level and the change value of the weight of the barrel, and the linkage calibration is finished after the water level falls to minus 2500mm and is stabilized.

And then, converting the weight change of the cylinder body (namely the weight change of water in the cylinder body) in the water level rising-falling process into the measured water replenishing variable quantity (mm), analyzing the measured water replenishing variable quantity (mm) by combining the actual water replenishing weight (mm) based on the peristaltic pump and the leakage quantity (mm) obtained by detecting the leakage container by the second weight detection module, and establishing the corresponding relation between the weight difference of the cylinder body, the water replenishing quantity of the peristaltic pump and the leakage quantity of the cylinder body. Exemplarily, as shown in a diagram of fig. 5, it was found that the weight change during the water replenishment and the leakage coincides with the trends of the water replenishment amount and the leakage amount; the weight variation is smaller than the water replenishing amount due to the influence of soil evaporation on the surface of the cylinder, but the influence of the evaporation amount on the leakage amount is small due to the fact that the time of the leakage process is shorter than the water replenishing time, and the two curves almost coincide. The weight difference, the accumulated water replenishing quantity and the accumulated leakage quantity are compared and analyzed pairwise, and then the first weight detection module is corrected again according to the difference value between the actual weight variation corresponding to the water replenishing quantity and the weight variation detected by the first weight detection module in the water replenishing period, so that the accuracy of the first weight detection module is improved.

As shown in the B diagram of fig. 5, the slope between the accumulated water supply amount and the accumulated leakage amount is close to 1, and the correlation coefficient is 0.998, i.e., the correlation between the accumulated water supply amount and the accumulated leakage amount is extremely high in the case of variation in the water level at the same height; similarly, the correlation coefficients between the accumulated water replenishing height value and the accumulated leakage amount and the weight difference are both 0.999, namely, the water replenishing amount and the leakage amount of the peristaltic pump are both related to the change of the weight of the cylinder body, and the deviation is 0.001.

Based on the design, the accuracy and the reliability of monitoring data of the lysimeter are improved by water supplement-leakage-weight linkage calibration.
