Description

Technical Field

Background Art

[0002] Agricultural and photovoltaic complementarity is a mode that combines agriculture and photovoltaic power generation. By installing photovoltaic modules on farmland, it can not only generate electricity but also carry out planting, achieving the mutual benefit and coexistence of agriculture and photovoltaic power generation. This mode can increase land use efficiency, promote the development of renewable energy, and realize the sustainable development of agriculture and energy. In existing agricultural and photovoltaic complementary projects, due to the installation of photovoltaic panels, the implementation of conventional irrigation is affected. Conventional irrigation methods are mainly manually controlled, and people subjectively judge when irrigation is needed and how much water needs to be irrigated. Under-irrigation is not conducive to crop growth, and over-irrigation will cause water waste, especially in arid areas such as the northwest, where water sources are tense during the irrigation season. Photovoltaic panels are mostly fixed on fixed brackets, and the height and tilt angle cannot be adjusted, so it is impossible to ensure that the crops below obtain the best sunlight while meeting the power generation requirements, and thus it is impossible to achieve the maximum power generation and the maximum yield.

[0055] A drainage pipe 11 is provided along the outer edge of the photovoltaic panel 6. The drainage pipe 11 is U-shaped, that is, the drainage pipe 11 is a U-shaped pipe; the highest point of the U-shaped pipe is flush with the photovoltaic panel 6. Drainage holes 8 are provided at the four corners of the drainage pipe 11. The drainage holes 8 are connected to the water inlet holes 10 on the water storage tank 5 through connecting water pipes 9. When rain comes or there are external water sources such as cleaning wastewater, the rain / cleaning wastewater flows from the drainage hole 8 at the lowest position into the water storage tank 5 from the photovoltaic panel 6 according to the action of gravity.

[0056] Refer to Figure 3 , the water inlet holes 10 on the upper surface of the water storage tank 5 are respectively located at the four corners of the upper surface of the water storage tank 5, the connecting water pipes 9 connected to the water inlet holes 10, the water outlet holes at the four corners of the lower surface of the water storage tank 5, refer to Figure 3 , the two water pipes 12 arranged crosswise inside the water storage tank 5.

[0057] In addition, the transmission poles can be arranged inside each base 1 of the fixing device to output the electric energy after photovoltaic conversion to supply power to the rainwater collection and irrigation device and the fixing device.

[0058] Refer to Figure 3 , two water pipes 12 arranged crosswise inside the water storage tank 5 are connected by a spring at the center. Among them, the two crosswise arranged water pipes and the centrifugal pumps and three-way joints at both ends have exactly the same structure. It can be referred to Figure 6 , which shows the structure of one of the two crosswise arranged water pipes. When rain comes or there is cleaning wastewater, the rain / cleaning wastewater, according to the action of gravity, flows from the drainage hole 8 at the lowest position through the connecting water pipe 9 from the photovoltaic panel 6 into the water inlet hole 10 on the upper surface of the water storage tank.

[0059] The water inlet holes 10 at the four corners of the upper surface of the water storage tank 5 are all connected to the upper water pipes 16 of the corresponding three-way joints. There are water outlet holes at the four corners of the lower surface of the corresponding water storage tank 5, and the opening and closing of the water outlet holes are controlled by valves. When the water storage tank 5 needs to be filled with water, the water inlet hole 10 at the lowest position is opened, and the centrifugal pump 18 pumps water directly from the lowest part of the water storage tank 5 to the highest part of the water storage tank through electricity, and flows out through the upper water pipe 16 of the three-way joint on the other side of the crosswise arranged water pipe, and is stored in the water storage tank 5 according to the action of gravity. That is, it flows into the upper water pipe 16 of the three-way joint from the water inlet hole of the water storage tank 5.

When the water storage tank 5 needs to discharge water, the centrifugal pump 18 at the lowest position starts to work, and pumps the water source at the lowest position in the water storage tank 5 to the highest position through the crosswise arranged water pipe 12. At this time, the intercept valves of the upper water pipe 16 and the lower water pipe 17 of the three-way joint closest to the centrifugal pump 18 at the lowest position are both opened, and the intercept valve in the lower water pipe 17 on the other side is opened, and the rest of the intercept valves remain closed, and the water can flow from the highest position to the sprinkler pipe network 13 arranged under the water storage tank 5.

[0061] Furthermore, a partition board is arranged on the inner lower surface of the water storage tank 5 parallel to the four sides, and several uniform water storage spaces are formed inside the water storage tank 5 through the partition board. When external water sources enter, water can flow between the water storage spaces, and the water enters the water storage tank more evenly, ensuring the weight balance of the water storage tank 5 and being beneficial to the stability of the water storage tank 5.

[0070] Step 702, the data analysis module determines the weather forecast information based on the meteorological data and a preset mesoscale meteorological forecast model; determines the crop light data based on the weather forecast information and a preset crop model; determines the irrigation decision data based on the weather forecast information and a preset crop model;

[0071] The data analysis module may be installed with a mesoscale meteorological forecast model and a preset crop model. The mesoscale meteorological forecast model can, according to the received meteorological data, make a rolling forecast of the weather conditions for a future period, such as a rolling forecast of the weather conditions within 15 days. The preset crop model predicts the crop growth trend and water use efficiency based on different irrigation schemes, and forecasts the irrigation amount for the next 15 days based on the optimal irrigation scheme.

[0072] The data analysis module then determines the weather forecast information based on the meteorological data and the preset mesoscale meteorological forecast model; it can also determine the crop light data based on the weather forecast information and the preset crop model, and combine the weather forecast information and the crop light data to determine the irrigation decision data.

[0073] In summary, it can be seen that the data analysis module has the function of irrigation decision analysis. On the one hand, it can formulate a reasonable irrigation plan according to the daily precipitation in the future and the water demand of the crops, and report it to the farmland management party for the management party to formulate a water transfer plan. On the other hand, it can judge whether irrigation is needed according to the precipitation prediction situation on each day and within the specified future dates. If irrigation is needed, it can judge the amount of irrigation.

[0074] Step 703, the control module adjusts the inclination angle of the photovoltaic panel according to the crop light data, and / or controls the operation of the centrifugal pump, and / or controls the opening and closing of the controllable intercept valves in the upper water pipe and the lower water pipe of the three-way joint, and / or controls the opening and closing of the water outlet hole of the water storage tank, and / or controls the irrigation of the sprinkler irrigation network 13 according to the irrigation decision data.

[0075] The control module can obtain the irrigation instruction based on the irrigation decision data, and by sending an instruction to the sprinkler pipe network 13, control the opening and closing of the controllable intercepting valves in the upper water pipe and the lower water pipe of the three-way joint and control the opening and closing of the water outlet hole of the water storage tank, so as to control the sprinkler pipe network 13 under the photovoltaic panel for irrigation. If the water storage is insufficient, the control instruction will be transmitted to the drip irrigation device on the farmland for irrigation. And when it is determined that light needs to be provided for the crops under the photovoltaic panel, the inclination angle of the photovoltaic panel can be calculated based on the crop light data given by the crop model, and the inclination angle of the photovoltaic panel can be adjusted by adjusting the height of the corresponding support column of the photovoltaic panel.

[0076] In the embodiment of the present invention, according to the optimal lighting scheme given by the crop model and the photovoltaic power generation requirement, the inclination angle of the photovoltaic panel is calculated by using the optimization model, and the inclination angle of the photovoltaic panel is adjusted by adjusting the height of the support column of the photovoltaic panel, so as to obtain higher crop yield and improve the light energy utilization rate while meeting the power generation requirement; and the rainwater collection and irrigation device under the photovoltaic panel can be controlled for irrigation, so that the water source outside the irrigation system can be used for irrigation, and the utilization rate of the external water source is improved.

[0077] Furthermore, historical meteorological monitoring data can be integrated as a reference, and the irrigation decision data can be determined based on the historical meteorological monitoring data, weather forecast information and the preset crop model. The specific process is as follows:

[0078] Based on the DSSAT crop model and the field experiment results, by setting different irrigation simulation schemes (i.e., different irrigation quota and irrigation time interval simulation schemes) and the daily average total solar radiation, the crop yield and water use efficiency are simulated. Based on the curve fitting method, a set of irrigation schemes and the daily average total solar radiation with larger crop yield and higher water use efficiency are selected, which are the optimal irrigation scheme and the daily average total solar radiation in this area. The setting of the irrigation scheme is as follows:

[0079] Calculated based on the meteorological information ET c (crop evapotranspiration) and P (precipitation) of the daily difference cumulative amount for irrigation, that is, when the cumulative amount of the past few days without irrigation date (since the last irrigation time to the current) reaches a certain value (such as 25mm, 30mm, 35mm) and within the specified future date (such as within 3 days from the current to the future) reaches a certain value (such as 25mm, 30mm, 35mm), irrigation is carried out. Considering the future weather forecast information during a single irrigation can avoid the situation of raining just after irrigation when only considering the before the current date, saving water resources to the greatest extent and fully considering that the crop yield and water use efficiency reach the optimum.ET c The single crop coefficient method is used for calculation, and the formula is as follows:

[0080]

[0081] In the formula, is the crop coefficient, and the reference value of the crop coefficient given by FAO-56 can be referred to; it is calculated through the Penman-Monteith formula , that is

[0082]

[0083] In the formula, is the reference crop evapotranspiration (mm); is the net radiation ( ); G is the soil heat flux ( ); is the psychrometer constant ( ); is the wind speed ( ); T is the air temperature (°C); is the saturation vapor pressure (kPa); is the actual vapor pressure (kPa); is the slope of the saturation vapor pressure (kPa·°C -1 ). Among them, the meteorological data before the current date comes from the data collected by various meteorological sensors obtained from the regional meteorological monitoring module, and the meteorological data after (including) the current date comes from the meteorological data predicted by the preset mesoscale meteorological forecasting model. The historical meteorological data is used to drive the crop growth model to simulate the crop yields and water use efficiencies obtained under different irrigation schemes, and a set of irrigation schemes with relatively large crop yields and relatively high water use efficiencies is determined as the optimal irrigation scheme for this area. Based on this optimal irrigation scheme, irrigation is carried out for this area.

[0084] In the non-growing season, the inclination angle of the photovoltaic panel is adjusted according to the principle of maximum power generation of the photovoltaic panel, and irrigation is not considered.

[0085] The crop growth model integrates the comprehensive research results of multiple disciplines. By quantitatively analyzing and calculating various factors affecting agricultural production, it can quickly reproduce the process of crop growth, development and yield formation, and can greatly reduce the time and space required for agricultural research. The DSSAT model is a computer crop simulation platform composed of growth models of various different crops. By inputting meteorological information, soil information, field management and other information into the model, the growth status of crops can be dynamically simulated, providing scientific and efficient decisions and countermeasures for natural resources, and it is one of the crop model systems widely used at present.
