Unmanned rice transplanter automatic steering control system and control method thereof

Abstract

The invention discloses an unmanned rice transplanter automatic steering control system and a control method thereof. The control system includes a main controller, a CAN bus communication unit, a GPS, an on position machine, a sensor module and a steering control module; the CAN bus communication unit is used for providing preset steering parameters, real-time display rice transplanter positions,speed, a handle position and the other information of the on position machine for the main controller; the GPS is used for determining the present position of the rice transplanter and transmitting the information to the on position machine, and the on position machine compares deviation of the present position and the target route; and the sensor module is used for transmitting the real-time operating information of the rice transplanter to the main controller. Compared with the prior art, the unmanned rice transplanter automatic steering control system and the control method thereof has thecharacteristics that a servo motor is used for controlling steering, the system structure is simple, the modular design is carried out and the maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an automatic steering control system for an unmanned rice transplanter and a control method thereof. Background technique [0002] At present, the existing agricultural machinery in production generally adopts manual driving and manual operation. When manually driving the rice transplanter, the soil conditions are changeable and the working environment is difficult. It has a great impact on the accuracy, and it is easy to produce defects such as duplication and omission, resulting in reduced production. [0003] In view of the monotonous and tedious work of the existing rice transplanter, researchers at home and abroad have begun to study the automatic driving technology of the rice transplanter. The National Agricultural Research Center of Japan has also transformed the original system of the rice transplanter, developed a steering execution system consisting of ...

Problems solved by technology

While researching on the navigation control of rice transplanters, domestic research institutions have also carried out preliminary explorations on the automatic control of rice transplanter planting operations. The speed change mechanism and planting operation mechanism of the rice transplanter have been electronically controlled by DC motors, and the steering mechanism, The automatic control of the transmission mechanism and the lifting mechanism of the implement, but the operation time of the electric control is longer than that of the driver, the operation is not flexible, the system reliability is low, the versatility is low and the cost is high, and it cannot meet the production requirements
