Description

Technical Field

[0001] The present invention belongs to the technical field of mine restoration, and in particular relates to a mine imported soil base material maintenance irrigation system and a quality detection and evaluation method thereof. Background Art

[0002] In mine reclamation and ecological restoration, the maintenance and irrigation of the imported soil substrate are crucial steps. This refers to an artificial substrate used in mine or environmental remediation projects to improve soil structure, increase nutrients, and promote vegetation growth. To ensure that the imported soil substrate effectively supports plant growth, it must be scientifically and rationally maintained and irrigated.

[0003] Traditional irrigation systems often waste water and fail to accurately provide necessary moisture. Furthermore, soil moisture, temperature, and pH are key factors influencing plant growth, making real-time monitoring and analysis of these parameters essential. Advanced sensing technology combined with automated control systems can achieve precision irrigation, significantly improving resource utilization efficiency.

[0004] Therefore, the temperature and pH value in the soil are collected in real time through the fiber optic sensor network, and comprehensive data processing and analysis are carried out through the central signal processor and computer, thereby providing a scientific basis for irrigation decision-making, maximizing the effectiveness of the imported soil substrate, and providing solid technical support for the green reclamation of mines. Summary of the Invention

[0005] The purpose of the present invention is to provide a mine imported soil substrate maintenance irrigation system and its quality detection and evaluation method, so as to solve the problems of water resource waste, insufficient soil environment detection, and inefficient delivery of nutrients.

[0006] To achieve the above-mentioned purpose, the present invention provides a mine imported soil substrate maintenance irrigation system, and adopts the following technical solutions:

[0007] A mine imported soil substrate maintenance irrigation system includes an irrigation device and a detection device. The irrigation device includes a primary water reservoir, a secondary water reservoir, an intelligent valve, and a ground-inserted sprinkler. The primary water reservoir and the secondary water reservoir are connected by a pipe. An intelligent valve is installed in the middle of the pipe. The intelligent valve controls and monitors the water level in the secondary water reservoir. The secondary water reservoir is connected to the ground-inserted sprinkler via a pipe. When the imported soil substrate needs water, the intelligent valve is opened to transfer water from the primary water reservoir to the secondary water reservoir. The ground-inserted sprinkler is used to replenish water to areas in the imported soil substrate that require water. The water level is monitored by the intelligent valve during the replenishment process. When nutrients are needed for the growth of the imported soil substrate, the intelligent valve is closed to replenish the required nutrients into the secondary water reservoir. The nutrients required by the imported soil substrate are replenished via the ground-inserted sprinkler.

[0008] The detection device includes a fiber optic sensor, an optical fiber, and a data acquisition and processing module. The fiber optic sensors are distributed in the soil, and adjacent fiber optic sensors are connected by optical fibers. The detected data is transmitted to the data acquisition and processing module in real time through the optical fiber. The data acquisition and processing module processes the received data, analyzes the quality of the imported soil substrate based on the processing results, and then controls the ground-inserted sprinklers to replenish water or nutrients to the imported soil substrate.

[0009] Furthermore, the data acquisition and processing module consists of a central processing unit and a computer. The optical fiber sensor transmits the detected optical signal data to the central processing unit via the optical fiber. The central processing unit converts the received optical signal data into electrical signal data, and the computer processes and analyzes the converted electrical signal data.

[0010] Furthermore, the smart valve is provided with a flow monitor, which monitors the amount of water in the secondary water reservoir.

[0011] Furthermore, when arranging the ground-inserted sprinklers, the spraying range between adjacent sprinklers reaches an overlap of 30-50% to ensure uniform irrigation; according to the actual shape and size of the site, the ground-inserted sprinklers are arranged in a trapezoidal or triangular shape, and the distance between adjacent sprinklers is controlled between 6-12 meters to avoid irrigation dead corners.

[0012] Furthermore, the optical fiber sensor includes a temperature sensor and a pH sensor; and the optical fiber sensing area of ​​the pH sensor is coated with a pH sensitive coating.

[0013] Furthermore, the temperature sensors and the pH sensors are arranged in a double-line parallel alternating distribution at a depth of 20-60 cm in the soil, that is, every two rows of temperature sensors are followed by two rows of pH sensors.

[0014] Furthermore, depending on the terrain, the temperature sensors and pH sensors are arranged and distributed in different ways. For square and flat terrain, the temperature sensors and pH sensors are arranged alternately in a grid or diagonal pattern. For circular terrain, the temperature sensors and pH sensors are arranged alternately in a radial pattern.

[0015] The specific process of using the mine imported soil substrate maintenance irrigation system to implement maintenance irrigation for the mine imported soil substrate is as follows: the temperature and pH value of the mine imported soil substrate are detected by the optical fiber sensor and transmitted to the central signal processor through the optical fiber. The computer processes the electrical signal data converted by the central signal processor, and analyzes the quality of the imported soil substrate based on the processing results; when the imported soil substrate needs to be replenished with water, the intelligent valve is opened to transport the water in the primary water reservoir to the secondary water reservoir, and the ground-inserted nozzle is used to replenish water to the area in the soil that requires water. The water volume is monitored by the intelligent valve during the replenishment process; when the growth of the imported soil substrate requires nutrients, the intelligent valve is closed, the required nutrients are added to the secondary water reservoir, and the nutrients required by the soil are replenished through the ground-inserted nozzle.

[0016] Furthermore, the present invention also protects a method for quality inspection and evaluation of irrigation for mining soil substrate maintenance using the above irrigation system, the method comprising the following steps:

[0017] S1. Classify the moisture content, temperature and pH value of the imported soil substrate into grade intervals;

[0018] S2. Calculate the total scores S1, S2, and S3 of the moisture content, temperature, and pH value of the imported soil substrate based on the scores of the measured moisture content, temperature, and pH value, and calculate the total score S4 for moisture conditions and S5 for nutrient conditions;

[0019] S3. According to the classification of moisture and nutrient conditions, the moisture and nutrient conditions of the guest soil substrate are determined based on the total moisture and nutrient condition scores.

[0020] Furthermore, the calculation formulas for the total water condition score and the total nutrient condition score are as follows:

[0021] S4=0.5S1+0.3S2+0.2S3

[0022] S5=0.3S1+0.3S2+0.4S3

[0023] Among them, S4 is the total score of water conditions, and S5 is the total score of nutrient conditions.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The mine imported soil substrate maintenance irrigation system provided by the present invention uses an intelligent control system to accurately replenish water according to the actual needs of the imported soil substrate, effectively saving water resources and avoiding waste; efficiently delivers nutrients to ensure that the nutrients are directly transported to the imported soil substrate, improving utilization efficiency; uses optical fiber sensors to monitor the imported soil substrate environment in real time, obtains data such as temperature and pH value, and provides a scientific basis for soil management; and uses intelligent data processing and analysis to adjust irrigation and nutrient delivery, reduce manual intervention, and improve soil quality and plant growth effects.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention are further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] like Figure 1-4As shown, the present invention provides a mine imported soil substrate maintenance irrigation system, which mainly includes an irrigation device and a detection device.

The intelligent valve 7 is fastened to the pipes between the primary water reservoir 1 and the secondary water reservoir 2 by a hexagonal screw 8. The intelligent valve 7 controls the water volume in the secondary water reservoir 2 and monitors the water volume in the secondary water reservoir 2 through its own flow monitoring meter 9. The secondary water reservoir 2 is connected to the ground-inserted sprinkler 3 through a pipe, and the required water or nutrients in the mine imported soil substrate are supplemented through the ground-inserted sprinkler 3. When the ground-inserted sprinkler 3 is arranged, the spraying range between adjacent sprinklers reaches an overlap of 30-50%. According to the actual shape and size of the site, it is arranged in a trapezoidal or triangular shape, and the sprinkler spacing is controlled between 6-12 meters.

[0035] The detection device includes an optical fiber sensor 4, optical fibers 10a, 10b, a central signal processor 5, and a computer 6; the optical fiber sensor 4 includes a temperature sensor 11 and a pH sensor 12, which are arranged in the soil in a double-line parallel alternating manner, a grid-like manner, or a diagonal manner as needed (e.g. Figure 4 As shown), adjacent optical fiber sensors are connected by optical fiber 10a, and the detected temperature and pH value are transmitted to the central signal processor 5 in real time by optical fiber 10b. The central signal processor 5 converts the received optical signal data into electrical signal data, and the computer 6 processes the converted electrical signal data. The quality of the guest soil substrate is analyzed according to the processing results, and then the ground-inserted sprinkler head 3 is controlled to replenish water or supplement nutrients to the guest soil substrate.

[0036] like Figure 5 As shown, the specific process of implementing maintenance irrigation on the mine imported soil substrate using the mine imported soil substrate maintenance irrigation system is as follows: the optical fiber sensor 4 includes a temperature sensor 111 and a pH sensor 12, and transmits the detected temperature and pH value of the imported soil substrate to the central signal processor 5 in real time through the optical fiber, which is converted into electrical signal data by the central signal processor 5 and output to the computer 6 for processing by the computer 6. The quality of the imported soil substrate is analyzed based on the processing results; when the imported soil substrate needs to be replenished with water, the intelligent valve 7 is opened to transport the water in the primary water reservoir 1 to the secondary water reservoir 2, and then to the ground-inserted sprinkler 3 to replenish the area in the soil that requires water. During the replenishment process, the intelligent valve 7 monitors the water volume in the secondary water reservoir 2 through the flow monitor 9; when the growth of the imported soil substrate requires nutrients, the intelligent valve 7 is closed, the required nutrients are added to the secondary water reservoir 2, and the nutrients required by the soil are replenished through the ground-inserted sprinkler 3.

[0037] like Figure 6As shown, the present invention also protects a method for quality inspection and evaluation of irrigation for imported soil substrate in mines using the above irrigation system, the method comprising the following steps:

[0038] S1. Classify the moisture content, temperature and pH value of the imported soil substrate into grade intervals;

[0039] S2. Calculate the total scores S1, S2, and S3 of the moisture content, temperature, and pH value of the imported soil substrate based on the scores of the measured moisture content, temperature, and pH value, and calculate the total score S4 for moisture conditions and S5 for nutrient conditions;

[0040] S3. According to the classification of moisture and nutrient conditions, the moisture and nutrient conditions of the guest soil substrate are determined based on the total moisture and nutrient condition scores.

[0050]

[0051] Table 3

[0052] The pH value scoring value is determined according to the pH value interval, and the total pH value scoring value S3 is calculated.

[0053] According to the total assigned values ​​of moisture content, temperature and pH value, the total score of water and nutrient conditions is calculated as follows:

[0054] S4=0.5S1+0.3S2+0.2S3

[0055] S5=0.3S1+0.3S2+0.4S3

[0056] Among them, S4 is the total score of water conditions, and S5 is the total score of nutrient conditions.

[0057] According to the total scores of moisture and nutrient conditions, the moisture and nutrient conditions are determined, as shown in Tables 4 and 5:
