PLC control system of orchard operation platform

The utility model relates to a PLC control system of an orchard operation platform. A user-defined control logic program is stored in a PLC of the PLC system. A local control panel is connected to the PLC and used for operation monitoring and local control of a production site. A wireless remote control terminal is connected to the PLC via a signal emitter and a wireless reception module, and is used for remote and wireless remote control over an orchard operation platform. A sensor, connected to the PLC, is used for detecting the running speed of a left crawler belt and a right crawler belt and the position of a lift oil cylinder, and also for monitoring the working state of the system. A solenoid valve, connected to the PLC, is used for controlling the rotating speed of a left driving motor and a right driving motor and controlling rising and descending of the oil cylinder. An alarming system, connected to the PLC, is used for detecting and determining faults of the system, and giving the alarm. Electronic control over the orchard operation platform can be achieved, conventional mechanical operation is changed, the workload is reduced, the work efficiency is improved, and the operation safety is improved.
