2. The plant protection system as described in claim 1 further includes a magnetic track and a sensing unit that is signal-connected to the control unit and electrically connected to the power supply unit. The carrying unit is disposed above the track and can move along the track. The walking module has a first drive wheel that is rotatable on one side of the base along a left-right direction, a second drive wheel that is rotatable on the other side of the base along the left-right direction, a driven wheel that is rotatably disposed on the base, a first motor connected to and used to drive the first drive wheel, and a second motor connected to and used to drive the second drive wheel. The base has a front end that is arranged opposite to the front-back direction perpendicular to the left-right direction. The system comprises a rear end and several support rods extending upwards along a height direction perpendicular to the left-right and front-back directions. A first drive wheel and a second drive wheel are located at the front end, and a driven wheel is located at the rear end. A platform assembly is connected to the top of the support rods. A control unit is signal-connected to the first motor and the second motor and is used to control them. The sensing unit includes a magnetic sensor located at the front end, suitable for detecting the magnetism of the track bar. The magnetic sensor has a first sensing part located on one side along the left-right direction and corresponding to the first motor, and a second sensing part located on the other side along the left-right direction and corresponding to the second motor. A third sensing unit is located between the first and second sensing units along the left-right direction. The control unit can switch between a forward mode, a first steering mode, and a second steering mode. When neither the first nor the second sensing unit detects magnetic force, but the third sensing unit detects the magnetic force of the track bar, the control unit switches to the forward mode. In the forward mode, the control unit controls the rotation speed of the first motor to be the same as that of the second motor, so that the rotation speed of the first drive wheel is equal to that of the second drive wheel, causing the carrying unit to move forward. The control unit controls the plant protection unit to generate short-wave ultraviolet light. When the first sensing unit detects the magnetic force of the track bar and the second sensing unit does not detect... When magnetic force is applied, the control unit switches to the first steering mode. In the first steering mode, the control unit controls the rotation speed of the second motor to be greater than that of the first motor, so that the rotation speed of the second drive wheel is higher than that of the first drive wheel. The control unit controls the plant protection unit to stop generating short-wave ultraviolet light. When the second sensing unit senses the magnetic force of the track bar and the first sensing unit does not sense the magnetic force, the control unit switches to the second steering mode. In the second steering mode, the control unit controls the rotation speed of the first motor to be greater than that of the second motor, so that the rotation speed of the first drive wheel is higher than that of the second drive wheel. The control unit controls the plant protection unit to stop generating short-wave ultraviolet light.

3. The plant protection system as described in claim 2, wherein, The track bar has a guide section and a stop section connected to the guide section. The control unit can also switch to a rotation mode. When the first sensing section, the second sensing section and the third sensing section simultaneously sense the magnetic force of the stop section, the control unit switches to the rotation mode. In the rotation mode, the control unit controls the first motor and the second motor to make the first drive wheel and the second drive wheel rotate in opposite directions. The control unit controls the plant protection unit to stop generating short-wave ultraviolet light.

4. The plant protection system as described in claim 2, wherein, The platform assembly is movably inserted through the support rods along the height direction.

5. The plant protection system as described in claim 2, wherein, The support unit also includes several guide wheels located on the outside of the base.

6. The plant protection system as described in claim 2, wherein, The platform assembly has two movably extending connecting rods through the support rods, and a platform connecting the connecting rods, on which the plant protection components are disposed.

7. The plant protection system as described in claim 6, wherein, The sensing unit also includes an ultrasonic sensor located at the front end. When the ultrasonic sensor detects an object approaching, it sends a signal to the control unit, causing the control unit to control the first motor, the second motor, and the plant protection components to stop operating.

8. The plant protection system as claimed in claim 6, wherein the supporting unit further includes two anti-collision strips respectively disposed at the front end and the rear end, and the sensing unit further includes two collision sensors respectively disposed within the anti-collision strips, wherein when the anti-collision strip is impacted, the collision sensor is impacted and transmits a signal to the control unit, causing the control unit to control the first motor, the second motor and the plant protection components to stop operating.

9. The plant protection system as described in claim 2, wherein, The base has two support rods, the platform assembly has two movably connected rods that pass through the support rods along the height direction, and two platforms that are connected to the connecting rods.
