The air temperature and humidity sensor 32 is used to detect the temperature and humidity of the air. The ultrasonic wind speed and direction sensor 31 emits a continuous variable frequency ultrasonic signal and detects the wind speed and direction by measuring the relative phase. The micro meteorological sensor 3 adopts an existing meteorological sensor, such as the NHQXZ-W-609 micro meteorological sensor produced by Wuhan Zhongke Nenghui Technology Development Co., Ltd., which can detect parameters such as wind speed, wind direction, atmospheric temperature, and atmospheric humidity. The wind speed measurement range is 0 to 40 m / s, the atmospheric temperature measurement range is -50°C to +80°C, the atmospheric humidity measurement range is 0 to 100%RH, the working voltage is 12VDC, and the operating environment is -40°C to +80°C, 0 to 100%RH. The camera 4 adopts an existing outdoor monitoring camera. The camera 4 is connected to the second bracket 12 through a telescopic rod 41. The telescopic rod 41 adopts an existing electric push rod and can adjust the height of the camera 4. The first working box 2 is arranged at a position slightly above the middle of the working rod 1. The micro meteorological sensor 3 and the camera 4 are both electrically connected to the first working box 2, so as to transmit data to the first working box 2.

[0027] As Figure 1As shown, the soil temperature and humidity sensor 61, the soil pH value sensor 62, and the soil nitrogen, phosphorus, and potassium sensor 63 are all connected to the first working box 2 through signal lines. The soil temperature and humidity sensor 61, the soil pH value sensor 62, and the soil nitrogen, phosphorus, and potassium sensor 63 are used to be inserted into the soil to obtain data.

[0028] As Figure 1 and Figure 5 shown, the solar panel 5 is connected to the working rod 1 in the area near the top. The solar panel 5 uses an existing solar panel and is electrically connected to the first working box 2 to provide power. In order to enable the solar panel 5 to adjust the angle, the solar panel 5 is movably connected to the working rod 1 through a driving component 7. The driving component 7 includes a first bracket 71, a driving motor 72, a driving lead screw 73, and a slider 74. The first bracket 71 is a horizontally arranged support plate. The driving motor 72 is arranged on the first bracket 71 and is electrically connected to the first working box 2. One end of the driving lead screw 73 is connected to the driving motor 72 and rotates under the drive of the driving motor 72. The other end of the driving lead screw 73 is connected to a support bearing 75. The slider 74 is movably connected to the driving lead screw 73. When the driving lead screw 73 rotates, it drives the slider 74 to move forward or backward. The lower end of the solar panel 5 is hinged to the top end of the slider 74 through a hinge shaft 52. Thus, when the driving motor 72 works, the lower end of the solar panel 5 can be driven to move through the driving lead screw 73 and the slider 74.

The four functional boxes 901 are connected to the fertilizer pump 92 through four branch pipes 902. A branch pipe valve 903 is provided on the branch pipe 902. The branch pipe valve 903 is electrically connected to the data acquisition and control module 22 inside the first working box 2. The fertilizer pump 92 is connected to the water replenishing pipe 94 through a fertilizing pipeline. The water replenishing pump 93 transports water to the required places through the water replenishing pipe 94 and a plurality of water replenishing branch pipes 95. When the soil nitrogen, phosphorus and potassium sensor 63 detects that the content of each element in the soil is low, the fertilizer pump 92 can be controlled to operate.
