DETAILED DESCRIPTION

[0033] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0034] First embodiment

[0035] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A structural schematic diagram of a first embodiment of an early warning method and device for saline-alkali land management and maintenance provided by the present invention; Figure 2 for Figure 1 A schematic cross-sectional view of the protective box shown; Figure 3 for Figure 2 An enlarged schematic diagram of part A is shown; Figure 4 for Figure 2 An early warning method for saline-alkali land management and maintenance comprises the following steps:

[0036] S1: According to the map of saline-alkali land to be treated, the saline-alkali land is divided into corresponding monitoring areas, and air sampling points are set up in different locations such as the central area, edge area, upwind direction and downwind direction of the saline-alkali land;

[0037] S2: The inspectors use the salt monitor probe to regularly inspect the divided areas;

[0038] S3: by obtaining the initial governance degree value of the monitoring instrument probe in each area, the second governance monitoring data collected by each saline-alkali land monitoring device within a preset time period is obtained, and the governance change difference calculation model is used for calculation, and then the governance change difference sequence and the difference between the governance change difference sequences are used to determine whether there is a warning plot to be governed, so as to generate warning information according to the warning plot to be governed and send it to the user terminal;

[0039] S4: At the same time, the air above the saline-alkali land is detected through the atmospheric detection device for saline-alkali land, and the detected data is sent to the governance change difference calculation model. While assisting in judging the soil condition according to the set governance change difference sequence, it generates warning information on whether it will bring new negative problems to the surrounding air environment and sends it to the user terminal;

[0040] S5: Staff will take targeted protective measures based on geological and air testing reports.

[0041] The saline-alkali land atmospheric detection device detects the saline-alkali land by combining long-term continuous monitoring with regular fixed-point monitoring.

[0042] Long-term continuous monitoring can be achieved with the help of automatic monitoring equipment, which can obtain the complete change curve of air indicators over time and understand the air conditions in different seasons and weather conditions.

[0043] Regular fixed-point monitoring is carried out in representative time periods, such as typical weather in different seasons, such as windy days in spring, hot days in summer, dry days in autumn, and cold days in winter, so as to compare and analyze the differences in air characteristics in different periods.

[0044] The user terminal can be a monitoring device designated by the user, or it can be the user's mobile phone, computer and other devices. The second governance monitoring data can be the soil water conductivity obtained by the user after collecting samples on site in the saline-alkali land. In actual use, the collection time of the first governance monitoring data and the second governance monitoring data must be consistent. The collection time of the second governance monitoring data shall be based on the user's on-site sample collection time.

[0045] An early warning device for saline-alkali land management and maintenance, such as the salt monitor probe used in step S2, comprises: a mounting frame 1, a protective box 2 is fixedly connected to the surface of the mounting frame 1, a detection needle 21 is arranged inside the protective box 2, and a mobile frame 22 is fixedly installed on the surface of the detection needle 21;

[0046] The mounting frame 1 is used to support the protection box 2 and can be fixed by burying the mounting frame 1 in the soil.

[0047] A telescopic member 4 is fixedly mounted on the surface of the protective box 2 . A sliding structure 3 is disposed at one end of the telescopic member 4 . The sliding structure 3 includes a sliding hole 31 . The interior of the sliding hole 31 is slidably connected to a rear sliding rod 32 .

[0048] A sliding hole 31 is provided inside the mounting frame 1 and the protective box 2, and a sliding rod 32 is slidably connected inside the sliding hole 31. Both ends of the sliding rod 32 are respectively fixedly connected to the bottom of the movable plate at one end of the telescopic member 4 and the top of the movable frame 22, so as to drive the sliding rod 32 connected to the movable frame 22 to move up and down when the telescopic member 4 is started to telescope.

[0049] A photovoltaic panel 7 is fixedly mounted on one side of the protection box 2 for providing power to the telescopic member 4 and the detection needle 21 .

[0050] A storage battery matching the photovoltaic panel 7 is fixedly installed inside the protection box 2 for providing power to the telescopic member 4 and the detection needle 21, while the photovoltaic panel 7 is used to charge the storage battery.

[0051] Two moving grooves 5 are formed inside the protection box 2 , and moving blocks 51 are slidably connected inside the two moving grooves 5 .

[0052] One side of the two moving blocks 51 is fixedly connected to the two sides of the moving frame 22, and is used to drive the two moving blocks 51 to move up and down inside the two moving grooves 5 when the moving frame 22 moves up and down, thereby increasing the stability of the moving frame 22 when it moves up and down.

[0053] Two reset members 6 are disposed inside the protection box 2 . A reset sleeve 61 is disposed at one end of each of the reset members 6 . Cleaning members 62 are fixedly installed inside each of the reset sleeves 61 .

[0054] The reset member 6 is a spring telescopic rod, which is used to enable the cleaning member 62 to better contact with the surface of the detection needle 21 .

[0055] The cleaning member 62 is a cleaning sponge, which is used to clean the detection needle 21 when the detection needle 21 is taken out of the soil and passes through the cleaning member 62. The reset sleeve 61 is a semicircular sleeve.

[0056] By starting the telescopic member 4 to contract, the sliding rod 32 is driven to move downward inside the sliding hole 31, thereby driving the moving frame 22 connected to the detection needle 21 to move downward and insert into the soil to detect the soil.

[0057] When the detection is completed, the telescopic member 4 is started to extend, driving the sliding rod 32 connected to the moving frame 22 to move upward, thereby driving the detection needle 21 to move upward, and at the same time, the detection needle 21 is cleaned by the cleaning member 62 for convenient use downward.

[0058] The detection needle 21 can be fixedly installed at one position by the above method, so that the staff does not need to go to the site to operate during the test, thereby improving the work efficiency.

[0059] The working principle of an early warning method and device for saline-alkali land management and maintenance provided by the present invention is as follows:

[0060] When in use, according to the map of the saline-alkali land to be treated, the saline-alkali land is divided into corresponding monitoring areas, and air sampling points are set at different locations such as the central area, edge area, upwind direction and downwind direction of the saline-alkali land;

[0061] The inspectors use the salt monitor probe to regularly inspect the divided areas;

[0062] Through the initial governance degree value of the monitoring instrument probe in each area, the second governance monitoring data collected by each saline-alkali land monitoring device within a preset time period is obtained, and the saline-alkali land governance degree change value corresponding to the same partitioned plot set is determined according to the initial governance degree value and the second governance monitoring data. The saline-alkali land governance degree change value corresponding to each partitioned plot set is input into the governance change difference calculation model to determine the governance change difference sequence between each partitioned plot set. Based on the difference between each governance change difference sequence, it is determined whether there is a warning plot to be governed, so as to generate warning information according to the warning plot to be governed and send it to the user terminal;

[0063] At the same time, the air above the saline-alkali land is detected through the atmospheric detection device for saline-alkali land, and the detected data is sent to the governance change difference calculation model. While assisting in judging the soil condition based on the set governance change difference sequence, it generates early warning information on whether it will bring new negative problems to the surrounding air environment and sends it to the user terminal.

[0064] Staff took targeted protective measures based on geological and air testing reports.
