Description

These systems integrate multiple technologies such as the Internet of Things, big data, cloud computing, and artificial intelligence, aiming to achieve comprehensive and accurate monitoring of the farmland environment and crop growth status.

[0024] In practical use, those skilled in the art can send instructions to the controller of the wheeled mobile robot 10 via a remote terminal, and the control device will start and move to the designated monitoring area. The specific usage steps are as follows: Step 1, Drilling Operation: The controller starts the second horizontal electric push rod 31, pushing the second horizontal plate 32 to move laterally along the second horizontal guide rod 33, moving the entire drilling assembly to directly above the through hole 11 and aligning it with the position to be monitored; then, the controller starts the second vertical electric push rod 34, pushing the second support plate 35 to move downward along the second vertical guide rod 36, moving the drill rod 392 closer to the soil surface; at the same time, the controller starts the servo motor 39, which drives the rotating shaft 38, rotating plate 391, and drill rod 392 to rotate at high speed. The drill rod 392 drills downward into the soil during rotation until it reaches the preset detection depth, completing the pre-opening of the detection hole; after drilling is completed, the controller stops the servo motor 39, the second vertical electric push rod 34 retracts, moving the drill rod 392 upward to reset, and the second horizontal electric push rod 31 retracts, moving the drilling assembly laterally to reset and move away from the through hole 11.
[0025] The second step is the monitoring operation: The controller activates the first horizontal electric push rod 21, pushing the first horizontal plate 22 to move laterally along the first horizontal guide rod 23, causing the insertion component and soil monitoring sensor 27 to move directly above the through hole 11, aligning the probe 28 with the pre-drilled detection hole; then, the controller activates the first vertical electric push rod 24, pushing the first support plate 25 to move downward along the first vertical guide rod 26, causing the soil monitoring sensor 27 to move downward, so that the probe 28 is inserted into the soil in the detection hole. The soil monitoring sensor 27 begins to collect parameters such as soil temperature, humidity, and pH, and transmits the monitoring data to the controller in real time. The controller processes the data and sends it to a remote terminal for staff to view; after monitoring is completed, the controller retracts the first vertical electric push rod 24, causing the soil monitoring sensor 27 and probe 28 to return to their original position, and the first horizontal electric push rod 21 retracts, causing the insertion component to return to its original position laterally.
[0026] The third step is the cleaning operation: The controller starts the third horizontal electric push rod 41, which pushes the third horizontal plate 42 to move laterally along the third horizontal guide rod 43, moving the cleaning assembly to directly above the through hole 11, so that the cleaning hole 44 is aligned with the reset probe 28; then the controller starts the first vertical electric push rod 24 again, pushing the probe 28 into the corresponding cleaning hole 44, and at the same time controls the water pump 46 to start. The water pump 46 draws water from the water tank 45 through the water inlet pipe 47 and sprays it onto the probe 28 through the water spray pipe 48. Together with the brush bristles in the cleaning hole 44, the soil particles on the surface of the probe 28 are rinsed and brushed to clean the probe 28; after cleaning, the controller stops the water pump 46, the first vertical electric push rod 24 retracts, and the probe 28 is disengaged from the cleaning hole 44. The third horizontal electric push rod 41 retracts, and the cleaning assembly is reset laterally.
[0027] After completing the monitoring of the area, the controller controls the wheeled mobile robot 10 to move to the next monitoring area, repeating the above steps to achieve real-time online monitoring of a large area of farmland.
