[0064] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0065] The embodiment of the present invention provides an irrigation method and system based on a river valley irrigation area to solve the problem of how to make full use of the unique terrain advantages of the river valley irrigation area and build an efficient, economical and energy-saving irrigation system, that is, a water supply and distribution pipe network system, according to local conditions.

[0066] An embodiment of the present invention provides an irrigation method embodiment based on a river valley type irrigation area. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0067] Figure 1 It is a schematic diagram of the flow of an irrigation method based on a river valley irrigation area according to an embodiment of the present invention.

[0068] like Figure 1 As shown, an irrigation method based on a river valley type irrigation area is provided in an embodiment of the present invention, which is applied to an irrigation system based on a river valley type irrigation area. The irrigation method based on a river valley type irrigation area includes:

[0069] S101: Determine a target hydropower station according to location information of a river valley irrigation area, and obtain a first power generation amount.

[0070] In this embodiment, the target hydropower station is used to provide irrigation water and generate power by differential pressure to the river valley irrigation area based on the reservoir corresponding to the target hydropower station. The target hydropower station is an upstream hydropower station related to the river valley irrigation area. The first power generation is the power generated by differential pressure power generation, which is applied to the river valley irrigation area.

[0071] In this embodiment, irrigation water is provided to the valley-type irrigation area by reservoirs and rivers flowing into the valley.

[0072] In this embodiment, it is necessary to determine the location information of the valley irrigation area. According to the location information of the valley irrigation area, the water supply distance S to the valley irrigation area is n Less than or equal to the preset distance S maxThe upstream hydropower station is determined as the target hydropower station. Specifically, the location information of the valley irrigation area can be used to determine whether there are any reservoirs or hydropower stations under construction or planned in the surrounding area. Instead of using traditional concrete channels or earth channels to transport water, large or medium-sized hydropower stations are used to provide water sources for the downstream, while making full use of the advantageous water head of mountain reservoirs for head drop power generation, and the first power generation W is obtained. n .

[0073] As an example, the precise geographic location information of the valley irrigation area, including longitude and latitude, can be obtained by using Geographic Information System (GIS) technology or satellite remote sensing technology. The preset distance can be determined based on the total water demand of the valley irrigation area and the water supply capacity of the hydropower station, and all hydropower stations within the preset distance will be considered as target hydropower stations. For example, if the total water demand of the valley irrigation area is relatively large and the water supply capacity of the surrounding hydropower stations is relatively weak, a relatively large preset distance can be set. By comparing the water supply distance between the hydropower station and the valley irrigation area and the preset distance, the hydropower station within the preset distance is selected as the target hydropower station. This step can be achieved by programming algorithms to determine the target hydropower station in an automated manner. The precise geographic location information of the hydropower station and the valley irrigation area, including longitude and latitude, can be obtained through the geographic information system. GIS technology can process and analyze spatial data to help determine the distance of the actual water supply path between the target hydropower station and the valley irrigation area. The spatial analysis tools of GIS software can be used to calculate the water supply distance between the hydropower station and the valley irrigation area. In addition, GIS technology can be used to conduct terrain analysis, taking into account natural features such as terrain undulations, rivers, and canyons, and assessing the impact of terrain on water supply distance.

[0074] In this embodiment, it is considered that the first power generation may or may not meet the electricity demand of the valley irrigation area, so as to achieve energy conservation and emission reduction while ensuring the electricity demand of the valley irrigation area.

[0075] As an example, the first power generation (the power generated by the step-down power generation) can meet the power demand of the valley irrigation area (the power demand of the valley irrigation area is W min ), that is, when the actual electricity consumption of the valley-type irrigation area is less than or equal to the first power generation, only the power generation generated by the step-down power generation is applied to the valley-type irrigation area.

[0076] As another example, the first power generation (the power generated by the step power generation) cannot meet the power demand of the valley irrigation area (the power demand of the valley irrigation area is W min), that is, when the actual power consumption of the valley irrigation area is greater than the first power generation, the second power generation and the third power generation are obtained, and a joint scheduling model is determined according to the first power generation, the second power generation and the third power generation, and power is supplied to the valley irrigation area based on the joint scheduling model. The second power generation is the power generated by wind power generation, and the third power generation is the power generated by photovoltaic power generation.

[0077] If the amount of electricity generated by the drop power generation is W n Cannot meet the electricity demand of valley irrigation areas min In mountainous areas, we combine the abundant wind and light resources to carry out wind power generation and photovoltaic power generation, and establish a "water-wind-light" joint scheduling model.

[0078] The formula corresponding to the “water-wind-solar” joint dispatch model is:

[0079] A=∑(W n1 +W n2 +…W nn )+∑(W m1 +W m2 +…W mm )

[0080] +∑(W i1 +W i2 +…W ii )+W lost , A ≥ W min

[0081] Where A represents the total power generation, W nn represents the first power generation corresponding to the power generation unit of the nth hydropower station, W mm represents the second power generation corresponding to the m-th wind power generation unit, W ii represents the third power generation corresponding to the ith photovoltaic power generation unit, W min represents the electricity demand of the valley irrigation area, W lost It is the loss value in the process of energy transportation.

[0082] S102: Based on the geomorphic features of the valley-type irrigation area, determine the highland area, and divide the valley-type irrigation area into at least one irrigation unit with the highland area as the center.

[0083] In this embodiment, the highland area is an area whose elevation difference with the surrounding area is greater than a preset value. The landform features include topographic features and geological features. The irrigation unit is the irrigated farmland.

[0084] As an example, the precise terrain features of the valley irrigation area can be obtained based on the geographic information system and the digital elevation model. Digital elevation data can provide elevation information of the terrain, which helps to identify the undulation and slope of the terrain. Through the terrain analysis tools of the GIS software, such as slope and aspect analysis, a preset value is set. By comparing the elevation data of the surrounding adjacent areas, the area whose minimum elevation difference with the surrounding area is greater than the preset value can be determined as the highland area. This can be achieved by creating contour maps and elevation stratification, so as to intuitively identify the highland area. At the same time, the terrain of the highland area should be flat, the groundwater level is not high, and the stability is good (not prone to landslides and collapses). Specifically, GIS technology and digital elevation model data can be used to analyze the slope and elevation changes of the highland area. The flatness of the terrain can be evaluated by the mean and standard deviation of the slope. Areas with small slopes and little change can be considered to have flat terrain. Groundwater level data can be obtained through groundwater level monitoring technology. Common methods include well water level method, water level meter method and radio method. These methods can understand the changes in groundwater levels in real time, so as to determine the height of the groundwater level. Geological surveys can be carried out, including ground mapping, drilling, well exploration, trench exploration, etc., to understand the structural characteristics of the landslide body, slide belt and slide bed, especially the basic properties and physical and mechanical characteristics of the slide belt. The stability of the slope can be evaluated using landslide stability analysis methods, such as the limit equilibrium method and the finite element method. These methods can determine the stability of the slope by calculating the safety factor. A safety factor greater than 1 indicates stability, equal to 1 indicates a limit equilibrium state, and less than 1 indicates instability. Through the above technical solutions, the flatness of the terrain, the height of the groundwater level and the stability of the terrain can be effectively determined.

[0085] In this embodiment, based on the topographical and geological characteristics of the valley irrigation area, the area whose elevation difference with the surrounding area is greater than a preset value is determined as a highland area, and the valley irrigation area is divided into different irrigation units X with the highland area as the center. j (j≥1). As an example, taking the highland area as the center, the valley irrigation area is divided into at least one irrigation unit in combination with factors such as topography, landform, water source conditions, soil type, and crop water demand characteristics. Hydrological analysis tools in GIS software, such as watershed division and river network extraction, can be used to assist in the division of irrigation units.

[0086] The irrigation unit is a component of the valley irrigation area. Each valley irrigation area operates independently and satisfies the following formula:

[0087] Among them, X j represents the jth irrigation unit, Indicates river valley irrigation area.

[0088] S103: Determine the water pump unit and high-level water tank unit corresponding to each irrigation unit.

[0089] In this embodiment, each irrigation unit is controlled by the corresponding water pump unit and high-level water tank unit to control water supply. The water pump unit is used to inject irrigation water into the high-level water tank unit. The high-level water tank unit is located in the highland area. The high-level water tank unit is used to store irrigation water. In this embodiment, a pipeline (specifically a second water pipeline) is provided between the water pump unit and the high-level water tank unit, and between the high-level water tank unit and the irrigation unit, and irrigation water is transported through the pipeline. The highland area is suitable for the construction of a high-level water tank unit. Dividing the irrigation unit with the highland area as the center can reduce the length of the pipeline, reduce costs, and realize self-pressure irrigation. The water pump unit is a water pumping station.

[0090] In this embodiment, each irrigation unit X j Water pump unit Y m (m≥1) and high level water tank unit Z i (i≥1) control. However, a single water pump unit can supply water to multiple high-level water tank units, and a single high-level water tank unit can also supply water to multiple irrigation units.

[0091] In this embodiment, the high-level water tank unit corresponding to each irrigation unit is determined, specifically including: determining the high-level water tank unit according to the geomorphic features of the highland area. Wherein, when the first pressure and the second pressure are different, a pressure reduction and energy dissipation unit is set, and the pressure difference between the first pressure and the second pressure is less than or equal to the maximum adjustment range of the pressure reduction and energy dissipation unit. The first pressure is the field irrigation pressure of the irrigation unit. The second pressure is the pressure of the irrigation water flowing out of the high-level water tank unit to reach the irrigation unit.

[0092] In this embodiment, the irrigation water can also be filtered by the sediment cascade treatment unit. The purpose of the sediment cascade treatment is to make the sediment content in the first water pipe less than the maximum sediment content in the irrigation system, and the sediment diameter in the first water pipe less than the maximum sediment diameter in the irrigation system.

[0093] As an example, the sediment cascade treatment unit usually includes a pre-pump filter and a post-pump filter, and the post-pump filter usually includes a post-pump screen filter and a post-pump laminated filter, wherein the mesh number of the pre-pump filter is generally set at about 80 meshes, and the mesh number of the post-pump filter is generally between 100 and 120 meshes. The water source at the lower part of the valley is filtered by the pre-pump filter of the sediment cascade treatment unit and enters the water pump unit. After being filtered by the post-pump filter of the sediment cascade treatment unit, it is pressurized and distributed to the high-level water tank unit by the water pump unit, and stored or discharged into the irrigation unit by the high-level water tank unit. The amount of water allocated to each irrigation unit by the high-level water tank unit can be determined according to the demand of each irrigation unit. Under normal circumstances, the amount of water allocated to each irrigation unit considering the loss of water that does not flow into the irrigation unit in the pipeline will be greater than the actual water demand of each irrigation unit. Therefore, when determining the demand of each irrigation unit, the loss can be directly added to the actual water demand to obtain the demand of each irrigation unit.

[0094] Considering that there are usually Figure 2 In the situation shown, there are common irrigation units and common high-level water tank units, that is, one irrigation unit c corresponds to two high-level water tank units at the same time (high-level water tank unit M and high-level water tank unit N are common high-level water tank units). Based on the above situation, the water storage capacity of a single high-level water tank unit is divided into two parts: a first water storage capacity and a second water storage capacity. The first water storage capacity supplies water to the irrigation unit corresponding to the high-level water tank unit alone, and the second water storage capacity supplies water to the irrigation unit corresponding to the high-level water tank unit and other high-level water tank units.

[0095] For a single high-level water tank unit, when there is a common irrigation unit, the first water storage capacity of the high-level water tank unit is equal to the sum of the water requirements of the irrigation units corresponding to the high-level water tank unit, and the water requirement of the common irrigation unit is less than or equal to the sum of the second water storage capacity of the common high-level water tank unit. Figure 2 As shown, there is a common irrigation unit c, and the common high-level water tank units are high-level water tank unit M and high-level water tank unit N. High-level water tank unit M includes a first water storage capacity M1 and a second water storage capacity M2, and high-level water tank unit N includes a first water storage capacity N1 and a second water storage capacity N2. The first water storage capacity M1 is equal to the sum of the water requirements of irrigation units a, b, and d, the water requirement of the common irrigation unit c is less than or equal to the sum of the second water storage capacity M2 and the second water storage capacity N2, and the first water storage capacity N1 is equal to the sum of the water requirements of irrigation units e and f.

[0096] For a single high-level water tank unit, when there is no common irrigation unit, the water storage capacity of the single high-level water tank unit is greater than or equal to the sum of the water demands of the irrigation units corresponding to the high-level water tank unit.

[0097] S104: Perform self-pressure irrigation according to the water head difference between the high-level water tank unit and the irrigation unit.

[0098] In this embodiment, the water head difference between the high-level water tank unit and the irrigation unit should satisfy that the pressure (second pressure) of the irrigation water flowing out of the high-level water tank unit reaching the irrigation unit is greater than or equal to the field irrigation pressure (first pressure) of the irrigation unit. The water head difference is specifically the dominant water head difference. The height difference between the high-level water tank unit and the irrigation unit fully meets the requirements of the field irrigation pressure. The corresponding P2-ΔP=P1, wherein P2 represents the second pressure, P1 represents the first pressure, and ΔP represents the pressure difference. The pressure reduction and energy dissipation are performed through the pressure reduction and energy dissipation unit.

[0099] In this embodiment, the high-level water tank unit should be selected in a terrain with flat terrain (the difference between the maximum elevation and the minimum elevation in the area is less than the preset elevation), low groundwater level (the depth of the groundwater level is less than the preset depth), and good stability (not prone to landslides and collapses). Specifically, the location of the high-level water tank unit can be determined according to the above-mentioned method of determining the highland area. The energy conversion relationship during self-pressure irrigation is based on the head difference between the high-level water tank unit and the irrigation unit: the position potential energy (height difference) is converted into pressure potential energy (which should be greater than the first pressure) through pipeline transportation to achieve self-pressure and gravity irrigation.

[0100] In this embodiment, the water pump water unit includes: a water pump, a first valve and a first water pipeline, and the first valve is provided at both ends of the first water pipeline.

As used below, the term "module" can implement a combination of software and / or hardware of a predetermined function. Although the system described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.

[0117] Figure 4 It is a structural block diagram of an irrigation system based on a river valley irrigation area according to an embodiment of the present invention.

[0118] This embodiment provides an irrigation system based on a river valley irrigation area. The irrigation system is applied to the technical solution of the irrigation method based on a river valley irrigation area, such as Figure 4 As shown, the irrigation system 10 based on the river valley irrigation area includes:

[0119] The first processing module 11, the second processing module 12, the third processing module 13, the fourth processing module 14, the self-pressure water supply and distribution module 15 and the power transmission line 16. The self-pressure water supply and distribution module 15 includes: a water pump unit 151 and a high-level water tank unit 152.

[0120] The first processing module 11 is used to determine the target hydropower station according to the location information of the valley irrigation area and obtain the first power generation. The target hydropower station is used to provide irrigation water to the valley irrigation area and perform differential power generation based on the reservoir corresponding to the target hydropower station. The target hydropower station is an upstream hydropower station related to the valley irrigation area. The first power generation is the amount of electricity generated by differential power generation, which is applied to the valley irrigation area.

[0121] The second processing module 12 is used to determine the highland area based on the geomorphic characteristics of the valley irrigation area, and divide the valley irrigation area into at least one irrigation unit with the highland area as the center. The highland area is an area whose elevation difference with the surrounding area is greater than a preset value.

[0122] The third processing module 13 is used to determine the water pump unit 151 and the high-level water tank unit 152 corresponding to each irrigation unit. Each irrigation unit is controlled by the corresponding water pump unit 151 and the high-level water tank unit 152. The high-level water tank unit 152 is located in the highland area. The water pump unit 151 is used to inject irrigation water into the high-level water tank unit. The high-level water tank unit 152 is used to store irrigation water.

[0123] The fourth processing module 14 is used to perform self-pressure irrigation according to the water head difference between the high-level water tank unit 152 and the irrigation unit.

[0124] The transmission line 16 is used to transmit the first power generation to the water pump unit 151 and the high-level water tank unit 152 corresponding to each irrigation unit. The water pump unit 151 is a water pumping station.

The first water delivery pipeline includes a water diversion pipeline of a water pumping station and a water delivery pipeline of a water pumping station, and the first valve includes a first water inlet valve arranged on the water diversion pipeline of the water pumping station and a first water outlet valve arranged on the water delivery pipeline of the water pumping station. The first water inlet valve is used to control the water flow entering the water pump. When the water pump needs to be started or stopped, it can be achieved by closing or opening the first water inlet valve. Before the water pump is started, ensure that the first water inlet valve is open so that irrigation water can enter the water pump. During the operation of the water pump, the first water inlet valve can also be used to adjust the water flow entering the water pump, thereby controlling the working efficiency of the water pump. The first water outlet valve is used to control the water flow leaving the water pump. By adjusting the opening of the first water outlet valve, the output flow and pressure of the water pump can be controlled to meet different irrigation needs. Before the water pump is started, the first water outlet valve is usually kept closed to ensure that there is sufficient water pressure when the water pump is started. Once the pump is started and running smoothly, the first outlet valve can be gradually opened to adjust the output flow and pressure. The first outlet valve can also be used to isolate the pump for maintenance or repair, or to quickly stop the water flow in an emergency.

[0126] The high-level water tank unit 152 includes: a high-level water tank, a second water delivery pipeline and a second valve, and the second water delivery pipeline is provided with a second valve. The second water delivery pipeline is a high-level water tank water delivery pipeline, and a second valve can be provided on the high-level water tank water delivery pipeline.

[0127] High-level water tank: used to store irrigation water lifted from the water pump unit 151, serving as an important buffer and regulating unit of the irrigation system. The high-level water tank can balance the peak-to-valley difference in water supply and ensure stable water supply of the irrigation system in different time periods. The design of the high-level water tank should meet the water demand of the irrigation unit corresponding to the high-level water tank unit 152. The high-level water tank should be built at a relatively high place so that water can be distributed in the pipe network through natural flow. The structure of the high-level water tank must be economical, stable and durable to withstand the pressure of water and the pressure of the external environment.

[0128] The water delivery pipeline of the water pump station is connected to the water pump unit 151 and the high-level water tank, and is responsible for delivering the irrigation water lifted by the water pump to the high-level water tank. The water delivery pipeline of the water pump station is provided with a first water outlet valve for controlling the entry and cutoff of water flow.

[0129] High-level water tank water delivery pipeline: connects the high-level water tank and the irrigation unit, responsible for delivering the water stored in the high-level water tank to the field. The high-level water tank water delivery pipeline is equipped with a second valve to control the output and cut-off of the water flow.

[0130] First inlet valve: It can be installed at the water inlet of the water diversion pipeline of the pumping station. It is mainly used to control the flow of irrigation water into the high-level water tank and cut off the water source when necessary. The first inlet valve can be used to adjust the water level, protect the water pump from backflow, and cut off the water flow in maintenance or emergency situations.

[0131] Second valve: It can be installed at the outlet of the water pipe of the high-level water tank, mainly used to control the flow of irrigation water from the high-level water tank and cut off the water source when necessary. The second valve can be used to adjust the distribution of irrigation water, prevent the waste of water resources, and cut off the water flow in maintenance or emergency situations.

[0132] Through the above arrangement, the high-level water tank unit 152 can effectively store and regulate irrigation water, and the first valve and the second valve provide necessary control and safety guarantees for the operation of the system.

[0133] As an example, the valves in the present invention (eg, the first valve and the second valve) may be electric valves.

The pressure reducing and energy dissipating unit 154 is set in an irrigation unit with different first and second pressures. The first pressure is the field irrigation pressure of the irrigation unit.

As an example, the third valve can also be an electric valve.

[0137] As an example, the specific connection relationship of each unit in the self-pressure water supply and distribution module 15 can be: the pre-pump filter in the sediment cascade treatment unit 153, the water pump water unit 151, the post-pump filter in the sediment cascade treatment unit 153, the high-level water tank unit 152 and the pressure reduction and energy dissipation unit 154.

[0139] The control and monitoring module 17 includes: a field monitoring unit 171 and a pipe network control unit 172 .

The field monitoring unit 171 includes data acquisition equipment, data integration equipment, communication equipment, etc. The data acquisition equipment may include: field soil moisture sensor, meteorological sensor, PH sensor, pressure sensor, flow sensor, and immersion liquid level transmitter (set in the high-level water tank). The basic data (such as humidity, meteorological data, PH value, pressure, flow, water level, etc.) are collected in real time through the data acquisition equipment, and the collected basic data are sent to the data integration equipment. The data integration equipment processes to obtain real-time monitoring data, which includes basic data and the water demand and the first pressure of each irrigation unit determined based on the basic data, and the water storage capacity and the second pressure of each high-level water tank unit 152. The real-time monitoring data is sent to the pipe network control unit 172 through the communication equipment.

[0141] The pipe network control unit 172 is used to perform feedback control according to the real-time monitoring data. Feedback control includes: adjusting the water storage capacity or the second pressure of the high-level water tank unit 152, or the amount of water allocated to the irrigation unit. Specifically, the water storage capacity, the second pressure or the amount of water allocated to the irrigation unit of the high-level water tank unit 152 is adjusted by adjusting the opening degree and opening time of the first valve, the second valve and the third valve. The pipe network control unit 172 can analyze and process the real-time monitoring data, determine the control strategy, and control it according to the control strategy to optimize the operation of the irrigation system.

[0142] In an optional embodiment, if Figure 4 As shown, the irrigation system 10 based on the river valley irrigation area also includes: a green power generation module 18.

[0143] The green power generation module 18 includes: a hydropower station power generation unit 181 , a photovoltaic power generation unit 182 and a wind power generation unit 183 .

[0144] The hydropower station power generation unit 181 includes: a turbine, a generator, a reservoir, a sluice gate and a third water delivery pipeline. The third water delivery pipeline includes: a hydropower station water diversion pipeline and a hydropower station water outlet pipeline.

[0145] The hydropower station power generation unit 181 is used to generate power by differential pressure to obtain a first power generation amount, and convert the dominant water head of the mountain reservoir into green and clean electric energy.

[0146] The photovoltaic power generation unit 182 is arranged on the water surface of the reservoir corresponding to the target hydropower station, and includes: photovoltaic panels, floating brackets, electrical equipment and a floating system.

[0147] The photovoltaic power generation unit 182 is used to perform photovoltaic power generation to obtain a second power generation amount. The surface space of the water body is utilized to fully utilize solar energy resources, and at the same time, water surface evaporation can be reduced and reservoir water quality can be improved.

[0148] The wind power generation unit 183 includes a wind turbine, a wind tower and a wind measurement system.

[0149] The wind power generation unit 183 is used to generate wind power to obtain a third amount of power. The mountain terrain features are fully utilized to effectively capture and utilize the wind energy resources in the mountainous area.

[0150] In an optional embodiment, if Figure 4 As shown, the control and monitoring module 17 in the irrigation system 10 based on the river valley irrigation area also includes: a power generation control unit 173.

[0151] The power generation control unit 173 is used to monitor the first power generation and various parameters of the hydropower station power generation unit 181, the second power generation and various parameters of the photovoltaic power generation unit 182, and the third power generation and various parameters of the wind power generation unit 183 in real time. The various parameters include voltage, current, frequency, etc., and adjust the operating status of each power generation unit according to the joint scheduling model, the first power generation and various parameters of the hydropower station power generation unit 181, the second power generation and various parameters of the photovoltaic power generation unit 182, and the third power generation and various parameters of the wind power generation unit 183. Based on the hydropower station power generation unit 181, the photovoltaic power generation unit 182 and the wind power generation unit 183, their various parameters are monitored in real time, and the operating status of the green power generation module is adjusted according to the joint scheduling model to ensure its safe and stable operation within the specified range.

[0152] In this embodiment, the green power generation module 18 changes the traditional external electricity consumption and adopts the comprehensive regulation of hydropower, photovoltaic power and wind power to provide the energy required in the irrigation system. The self-pressure water supply and distribution module 15 is based on the original irrigation area, changing the channel into a pipeline, and developing a "new era karez" irrigation system of "fall power generation-water pumping station-high-level water tank-self-pressure irrigation", realizing the green transformation of "potential energy-electric energy-potential energy", thereby improving energy utilization efficiency and water utilization efficiency. The control and monitoring module realizes the overall monitoring and regulation functions of the system on the basis of the green power generation module and the self-pressure water supply and distribution module, thereby realizing stable and safe production.

[0153] As an example, take the drip irrigation area as an example, Figure 5 , 6 As shown, if the original water delivery channel 15 is an earthen channel, its service life and leakage will lead to frequent repairs. If the water delivery channel 15 is a concrete channel, its engineering cost is too high. In addition, considering the natural advantage of the height difference of the mountain reservoir, the mode of "hydropower station water diversion pipeline 4-1, power station 4, hydropower station water outlet pipeline 4-2" is adopted to develop a large amount of green electricity that meets the electricity demand of the irrigation area, while avoiding a large amount of evaporation and leakage of the water delivery channel 15.

[0154] Furthermore, the power station 4 provides electric energy to the water pumping station 7 through the transmission line 5, avoiding the need for an external circuit 16 to provide electric energy, and the solar panel cluster 1 arranged on the surface of the reservoir is combined to achieve green agriculture.

[0155] Furthermore, instead of the pump station 7 directly pressurizing water to the drip irrigation area farmland 13 through the pump station water pipe 7-2, the high-level water tank 8 is used to supply water to the drip irrigation area farmland 13 through the high-level water tank water pipe 9, thereby making full use of the height difference between the high-level water tank 8 and the irrigation area farmland 13.

[0156] Furthermore, if the difference in elevation between the high-level water tank 8 and the irrigated farmland 13 is much greater than the required elevation difference, a pipeline power generation and energy dissipation device is installed to achieve energy dissipation and precision irrigation.

[0157] As another example, Figure 7 As shown, the irrigated farmland 13 is located on the river valley, forming a distribution pattern of "water in the river valley and fields on the river valley". The relative positions of the mountain reservoir 2 and the high-level water tank 8 are shown in the figure.

[0158] Furthermore, the elevation and number of the high-level water tanks 8 are determined by the location and elevation of the irrigated farmland 13 to ensure that all of the irrigated farmland 13 are within the irrigation range of the high-level water tanks 8 .
