[0034] The specific embodiments of this utility model will be described below with reference to the accompanying drawings.

[0035] Figure 1 An embodiment of an automated agricultural control system is shown, which consists of an intelligent control device 20, a weather information acquisition device 10, and an equipment execution device 40. The intelligent control device 20 is connected to the weather information acquisition device 10 via a first signal line 11, and the intelligent control device 20 is connected to the equipment execution device 40 via a second signal line 21.

[0036] like Figure 2As shown, the weather information acquisition device 10 has an I / O device 13, such as a keyboard and display 30, or a touch screen. The operator inputs weather information source parameters into the weather information acquisition device 10 through the I / O device 13. The weather information acquisition device 10 also has a network adapter 12, which connects to the wide area network (WAN) and retrieves weather forecast information from the internet based on the received weather information source parameters. The weather information acquisition device 10 includes a weather information storage 14 for storing the weather information source parameters, including the city name and the target server address. The weather information acquisition device 10 connects to the internet through the network adapter 12, accesses the target server on the internet, and queries the city weather forecast information corresponding to the city name on the target server. The query results of the weather forecast information are returned to the weather information acquisition device 10 and are also stored in the weather information storage 14. The content of the weather forecast information depends on the information provided by the server, but generally needs to include at least date information, weather type, temperature range, sunrise time, sunset time, air humidity, wind direction, wind speed, and ultraviolet radiation intensity, etc.

[0037] The weather information acquisition device 10 and the intelligent control device 20 are interconnected via a first signal line 11, and the weather forecast information is transmitted to the intelligent control device 20 via the first signal line 11. Figure 3 As shown, the intelligent control device 20 includes a control strategy memory 22, which stores a set of preset control strategies. These preset control strategies correspond to control methods for different agricultural equipment under various weather conditions. Specifically, each preset control strategy includes a sequence of multiple different control commands and the transmission time of each control command. Based on the received weather preset information, the intelligent control device 20 searches for a matching preset control strategy in the control strategy memory 22, and then sends the corresponding control command to the device execution device 40 via the second signal line 21 at a preset time point according to the content of the preset control strategy.

[0038] For example Figure 1As shown, the automated agricultural control system of this embodiment also includes a display 30. The display 30 displays the weather forecast information currently being transmitted to the intelligent control device 20, and also displays the control commands currently being executed by the device execution device 40. The display 30 is connected to the intelligent control device 20 via a third signal line 31. In this embodiment, the third signal line 31 shares a section of the same physical signal line with the first signal line 11. Specifically, the intelligent control device 20 is connected to the inlet of a switching device 32 via a physical line such as a network cable. The switching device 32 includes multiple outlets. The weather information acquisition device 10 is connected to one outlet via a network cable, and the display 30 is connected to another outlet via a network cable. Thus, the network cable connecting the intelligent control device 20 and the switching device 32 is shared by the first signal line 11 and the third signal line 31.

[0039] In this embodiment, one of the device actuators 40 is a roller shutter motor 41, used to automatically roll up and lower the curtain of the agricultural greenhouse. The intelligent control device 20 selects a corresponding preset control strategy based on weather type, sunrise time, and sunset time from weather forecast data. The control commands in the preset control strategy include the motor rotation direction and the number of rotations. At the time point corresponding to the preset control strategy, the intelligent control device 20 sends a start command to the roller shutter motor 41, rotating it in the specified direction a specified number of times. Different directions correspond to the rolling up and lowering of the curtain, and different numbers of rotations correspond to the rolling up and lowering amplitude of the curtain. Through these corresponding operations, the duration and intensity of sunlight in the agricultural greenhouse can be precisely controlled.

[0040] In this embodiment, another device 40 is a light switch 42, used to control the lights in the agricultural greenhouse. The intelligent control device 20 selects a corresponding preset control strategy based on the weather type, sunrise time, and sunset time in the weather forecast data. The control instructions in the preset control strategy include turning the lights on and off. The intelligent control device 20 sends a switch command to the lights at the time point corresponding to the preset control strategy. Through the corresponding operation, the lighting time and intensity in the agricultural greenhouse can be accurately controlled.

[0041] In this embodiment, another device 40 is a ventilation fan 43, used to control ventilation in the agricultural greenhouse. The intelligent control device 20 selects a corresponding preset control strategy based on the weather type and air humidity in the weather forecast data. The control instructions in the preset control strategy include ventilation on and ventilation off. The intelligent control device 20 sends a switch command to the ventilation fan 43 at the time point corresponding to the preset control strategy. Through the corresponding operation, the air humidity in the agricultural greenhouse can be accurately controlled.

[0042] In this embodiment, another device 40 is an irrigation nozzle 44, used for precise control of the irrigation system within the agricultural greenhouse. The intelligent control device 20 selects a corresponding preset control strategy based on weather type and air humidity data from weather forecasts. The control commands in the preset control strategy include irrigation water volume and irrigation flow rate. At the time point corresponding to the preset control strategy, the intelligent control device 20 sends a start command to the irrigation nozzle 44 to irrigate with a specified water volume at a specified flow rate. Through this corresponding operation, the frequency, water volume, and water flow rate of the automatic irrigation in the agricultural greenhouse can be precisely controlled.
