Description

Technical Field

[0001] The present invention relates to the technical field of atmospheric environment monitoring, and in particular to a dew amount monitoring method, system, electronic equipment and medium based on colorimetry. Background Art

[0002] Dew condensation is a common meteorological event and an important form of wet deposition. A moderate amount of dew can promote plant growth and replenish the water lost by plant transpiration, but too much dew will be detrimental to the spread of pollen. The heat consumed during the evaporation of dew will prolong the duration of low temperatures and increase the degree of cold damage to plants. Therefore, accurate measurement of dew can not only replenish wet deposition, but also provide a basis for judging the growth of plants / crops.

[0003] At present, the monitoring methods of dew are mainly divided into direct monitoring method (weight loss method) and indirect monitoring method (model method). The direct monitoring method is to convert the weight difference of the dew monitor in the morning and evening into the amount of dew condensation. Different types of underlying surfaces have different dew monitors. Currently, the most widely used monitors include poplar sticks, cloth pieces, plastic sheets, metal sheets, etc. This method is more accurate in calculating the amount of dew, but it has high requirements for the dew collection time, is labor-intensive, and is prone to certain errors when collecting or weighing the collector. Therefore, some progress has been made in the indirect monitoring of dew, such as using the dew amount and its influencing factors to construct a dew model. However, dew depends not only on local meteorological conditions, but also on the physical characteristics of the atmosphere and the surface, as well as the radiation, thermodynamics, and aerodynamics of the surrounding environment. Therefore, the above model is only applicable to a small local area and cannot be widely promoted and applied.

[0004] In summary, the direct monitoring method consumes manpower, and the indirect monitoring method requires a large amount of preliminary monitoring data to support it. Therefore, it is imperative to provide a method that has a wide range of applications, is simple and easy to use, and can accurately monitor the amount of dew. Summary of the invention

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0034] The object of the present invention is to provide a dew amount monitoring method, system, electronic equipment and medium based on colorimetry, which can improve the accuracy and applicability of dew amount monitoring.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1 As shown, the present invention provides a dew amount monitoring method based on colorimetry, comprising:

[0037] Step 1: Setting up monitoring points.

[0038] This method is applicable to terrestrial ecosystems, including forest ecosystems, grassland ecosystems, wetland ecosystems, farmland ecosystems and urban ecosystems. Monitoring points are set up in the central area of ​​the typical underlying surface of each ecosystem, and the monitoring points try to cover all underlying surface types in the domain. For example, urban ecosystems should be set up in green areas, hardened roads and bare soil areas; farmland ecosystems should be set up in typical crop areas; wetland ecosystems should be set up in typical plant areas (aquatic, xerophytic, etc.); grassland ecosystems should be set up in typical plant areas (short grass, shrubs, etc.); forest ecosystems should be set up in typical plant areas (trees, shrubs, etc.). The distance between each monitoring point should not be less than the radius of the monitoring area.

[0039] Step 2: Monitor placement and recovery.

[0040] 2.1 The structure of the monitor involved in the present invention is shown in the figure Figure 1 As shown in the figure: 1. air hole, 2. top cover, 3. top box, 4. middle box, 5. bottom box, 6. color-changing silica gel, 7. round tube with thread, 8. bracket connecting bracket, 9. fixed bracket, 10. height adjustment ring, 11. bracket fixing ring.

[0041] The monitor consists of an upper monitoring box and a lower bracket. The monitoring box includes a vent 1, a top cover 2, a top box 3, a middle box 4, a bottom box 5, a color-changing silica gel 6 and a round tube with threads 7. The bracket includes a bracket connecting bracket 8, a fixed bracket 9, a height adjustment ring 10, and a bracket fixing ring 11.

[0042] The top cover 2, the top box 3, the middle box 4 and the bottom box 5 are connected by threads, and the air holes 1 are evenly distributed on the top cover 2, the bottom of the top box 3 and the bottom of the middle box 4. The color-changing silica gel 6 is tightly spread in a single layer in the top box 3, the middle box 4 and the bottom box 5. The dew condensed at night can settle on the color-changing silica gel 6 through the air holes 1 on the top cover 2, and different amounts of dew can cause different color changes in the color-changing silica gel 6 in the top box 3. When the amount of dew is heavy or too heavy, the dew can seep into the middle box 4 or the bottom box 5, causing the color-changing silica gel 6 in the middle box 4 or the bottom box 5 to change in different colors.

[0043] The upper bottom box 5 and the lower fixed bracket 9 are connected via a round tube 7 with threads and a bracket connecting bracket 8 .

[0044] The height of the bracket part can be adjusted and kept level by the height adjustment ring 10 according to the type of the underlying surface and the height of the terrain at the monitoring point, and the bracket fixing ring 11 can keep the monitor stable.

[0045] The corresponding relationship between the color change of the color-changing silica gel 6 in the top box 3, middle box 4 and bottom box 5 of the monitor used in the present invention and the amount of dew is determined after repeated experiments, and the color error caused by the color-changing silica gel 6 due to moisture absorption and other processes has been eliminated. Since the amount of dew is related to the size and material of the monitor, the size and material of the bottom box 5 and the above parts of the monitor are fixed and cannot be replaced.

[0046] The monitor top cover 2, top box 3, middle box 4, bottom box 5 and round tube 7 with threads are all made of organic glass with a thickness of 2 mm.

[0047] Pore ​​1: size is a circle with a diameter of 2 mm;

[0048] The top cover 2, the top box 3, the middle box 4 and the bottom box 5 are all round boxes with a diameter of 150 mm and a height of 10 mm;

[0049] The color-changing silica gel 6 can be blue silica gel or orange silica gel, and the silica gel has a sphere with a diameter of 4-8 mm.

[0050] 2.2 Place the monitor at each monitoring point at sunset to ensure that the color-changing silica gel 6 is in its initial color, i.e., it is not hygroscopic or damp. Adjust the height and horizontal angle of the monitoring box through the height adjustment ring 10. If the lower surface is a plant, the height of the monitoring box is set at the plant canopy; if the lower surface is a grass or hard ground, place the monitoring box directly on the ground.

[0051] 2.3 Determine the dew amount at each monitoring point. Take back each monitor half an hour before sunrise and compare Figure 2 The color of the colorimetric card and the color-changing silica gel 6 in the top box 3, the middle box 4, and the bottom box 5 can be used to determine the amount of dew at each monitoring point on that day.

[0052] Color-changing silica gel 6 uses blue silica gel Figure 2Use the medium blue-pink color comparison card to compare colors; use orange silica gel for color-changing silica gel 6 Figure 2 Compare colors using the medium yellow-green color chart.

[0053] For example, if the color-changing silica gel 6 in the middle box 4 and the bottom box 5 is dark blue (not changed), observe the color of the color-changing silica gel 6 in the top box 3, determine the position on the colorimetric card, and read the value at the same time. If the color-changing silica gel 6 in the top box 3 has completely changed color, and the color-changing silica gel 6 in the bottom box 5 is dark blue (not changed color), observe the color of the color-changing silica gel 6 in the middle box 4, determine the position on the colorimetric card, and read the value at the same time. If the color-changing silica gel 6 in the top box 3 and the middle box 4 has completely changed color, observe the color of the color-changing silica gel 6 in the bottom box 5, determine the position on the colorimetric card, and read the value at the same time.

[0054] The color chart is divided into 8 areas. Figure 2 The dew volume in the display corresponds to the end value of each area, which can be directly read according to the position of the color-changing silica gel on the color comparison card. If the color of the color-changing silica gel 6 in the top box 3, the middle box 4, and the bottom box 5 changes unevenly, the color of more than 2 / 3 of the area shall be used as the standard for comparison.

[0055] If precipitation occurs during the dew condensation stage (from sunset to sunrise the next day), the dew amount on that day is zero.

[0056] Step 3: Determination of dew volume. Daily dew volume is the arithmetic mean of dew volume at each monitoring point in the area. Annual dew volume is the sum of daily dew volume in a natural year.

[0057] Step 4: Reuse of color-changing silica gel.

[0058] Color-changing silica gel 6 can be reused. Place the discolored silica gel in an oven or drying box at 100°C every day and dry it for 120-140 minutes depending on the degree of discoloration of the silica gel. For specific time, refer to Table 1. The silica gel that has restored its original color after drying can be reused, and if the silica gel is damaged, it can be discarded.

[0059] Table 1 Silica gel drying schedule

[0060]

[0061] According to the dew precipitation characteristics of the monitoring area and the color change rules of different types of color-changing silica gel, by determining the corresponding relationship between the color of the color-changing silica gel and different dew amounts, the structure, material, size and color change range of the color-changing silica gel of the monitoring box can be changed. For example, the monitoring box may be square, hexagonal or other shapes, the material may be stainless steel, plastic, etc., and the color-changing silica gel may change from green white to colorless, etc., all of which are within the protection scope of the present invention.

[0062] According to the current results of dew monitoring worldwide, the device monitoring box of the present invention is composed of a top layer, a middle layer and a bottom layer, which can basically cover the dew observation range of various ecosystems. For example, in areas where the daily dew amount is higher than 0.45 mm, the number of layers of the monitoring box can also be increased. The progressive relationship of the dew amount monitoring of each layer of the present invention is fixed, and it supports more than three layers of monitoring boxes to jointly monitor the dew amount threshold in areas with a wider range.

[0063] As a specific implementation method, taking Jingyue Development Zone in Changchun City, Jilin Province as an example, the following embodiment is provided.

[0064] Example 1:

[0065] Experimental location: Jingyue Development Zone, Changchun City, Jilin Province

[0066] The method for monitoring the amount of dew condensation in a city according to the present invention is carried out in the following steps:

[0067] Step 1: Set up monitoring points in the green land, hardened road surface and bare land of Jingyue Development Zone. The distance between each monitoring point should not be less than the radius of Jingyue Development Zone.

[0068] Step 2: Spread a single layer of spherical color-changing silica gel with an initial color of blue and a diameter of 5 mm tightly in the top box 3, the middle box 4, and the bottom box 5. During the frost-free period of Changchun City in 2024 (i.e., April 1 to October 30, 2024), the monitors will be distributed and placed at the green space, hardened road surface, and bare land monitoring points after sunset every day. In the green area, the monitoring box is kept horizontal and consistent with the height of the green plant canopy by adjusting the height of the fixed bracket. The monitoring boxes in the hardened road surface and bare area are placed directly on the ground. Ensure that the color-changing silica gel is the initial color and does not absorb moisture or get damp.

[0069] Take back each monitor half an hour before sunrise the next day, and determine the dew amount at each monitoring point by comparing the color of the blue-pink colorimetric card with the color of the color-changing silica gel in the top box 3, the middle box 4, and the bottom box 5.

[0070] Take the dew amount on July 20 as an example:

[0071] Green area monitoring box: the color-changing silica gel 6 in the middle box 4 and the bottom box 5 is dark blue (no color change), and the color of the color-changing silica gel 6 in the top box 3 is as follows: Figure 3 As shown in part (a), by comparing the position of the blue and pink color chart, it can be judged that the dew amount in the green area is 0.14 mm.

[0072] Hardened road surface monitoring box: The color-changing silica gel 6 in the middle box 4 and the bottom box 5 is dark blue (no color change), and the color of the color-changing silica gel 6 in the top box 3 is as follows: Figure 3 As shown in part (b), by comparing the position of the blue-pink color chart, it is determined that the dew amount in the hardened pavement area is 0.06 mm.

[0073] Bare soil area monitoring box: The color-changing silica gel 6 in the middle box 4 and the bottom box 5 is dark blue (no color change), and the color of the color-changing silica gel 6 in the top box 3 is as follows: Figure 3 As shown in part (c), by comparing the position of the blue-pink colorimetric card, it is determined that the dew content in the bare soil area is 0.01 mm.

[0074] Step 3: Determination of dew amount. The dew amount in Jingyue District, Changchun City on July 20 is the arithmetic mean of the green area, hardened road surface area and bare soil area, that is, 0.07 mm. If precipitation occurs during the dew condensation stage (from sunset to sunrise the next day), the dew amount on that day is 0. The dew amount in Jingyue District, Changchun City in 2024 is the sum of the daily dew amount in 2024, 14.0 mm.

[0075] Step 4: Place the discolored silica gel in an oven at 100°C every day and dry it for 120-140 minutes depending on the discoloration degree of the silica gel (Table 2). The silica gel that has returned to its original color after drying can be reused.

[0077]

[0078] Example 2:

[0079] Experimental location: Honghe Farm, Heilongjiang Province

[0080] The method for monitoring the amount of dew condensation in farmland of the present invention is carried out according to the following steps:

[0081] Step 1: Set up monitoring points in the center of the typical crop area of ​​Honghe Farm, including corn, soybeans and rice. The distance between each monitoring point should not be less than the radius of the Honghe Farm area.

[0082] Step 2: Spread a single layer of spherical color-changing silica gel with an initial color of orange and a diameter of 5 mm tightly in the top box 3, the middle box 4, and the bottom box 5. During the frost-free period of Honghe Farm in 2024 (i.e., April 20 to October 15, 2024), monitors will be placed at corn, soybean, and rice monitoring points every day after sunset. At each monitoring point, the monitoring box is kept horizontal and consistent with the height of the crop canopy by adjusting the height of the fixed bracket. Ensure that the color-changing silica gel is the initial color and does not absorb moisture or be affected by moisture.

[0083] Take back each monitor half an hour before sunrise the next day, and determine the dew amount at each monitoring point by comparing the color of the yellow-green colorimetric card with the color of the color-changing silica gel in the top box 3, the middle box 4, and the bottom box 5.

[0084] Take the dew amount on August 10 as an example:

[0085] Corn area monitoring box: The color-changing silica gel 6 in the middle box 4 and the bottom box 5 is dark blue (no color change), and the color of the color-changing silica gel 6 in the top box 3 is as follows: Figure 4As shown in part (a), by comparing the position of the yellow-green color chart, it is determined that the dew amount in the corn area is 0.11 mm.

[0088] Step 3: Determination of dew amount. The dew amount of Honghe Farm on August 10 is the arithmetic mean of the rice area, corn area and soybean area, which is 0.13mm. If precipitation occurs during the dew condensation stage (sunset to sunrise the next day), the dew amount on that day is 0. The dew amount of Honghe Farm in Heilongjiang in 2024 is the sum of the daily dew amount in 2024, 17.9mm.

[0089] Step 4: Place the discolored silica gel in an oven at 100°C every day and dry it for 120-140 minutes depending on the discoloration degree of the silica gel (Table 3). The silica gel that has returned to its original color after drying can be reused.
