Automatic control system for unmanned rice transplanters and control method thereof

Abstract

The invention provides an automatic control system for unmanned rice transplanters and a control method thereof in the technical field of agricultural control. The control system includes an upper computer, a lower computer, a communication unit, a Beidou differential positioning module, an inertial navigation module and a fertilizer-applying control module; a main variable speed handle angle sensor and a turning angle sensor respectively send a detected front wheel turning angle signal and main variable speed handle turning angle signal to the lower computer; the lower computer collects and processes the front wheel turning angle signal and the main variable speed handle turning angle signal, and transmits the processed front wheel turning angle signal and main variable speed handle turning angle signal to the upper computer; the upper computer sends motion instructions for controlling a stepping motor and a stepping electric push rod to the lower computer; the lower computer controlsthe motion of the stepping motor and the stepping electric push rod so as to make a rice transplanter to travel according to planned paths; a fertilizer tank weight sensor is connected between a fertilizer tank and a fertilizer discharging device; and the lower computer controls the rotating speed of a fertilizer discharging motor. Therefore, the simultaneous operation of rice transplanting and fertilizer applying can be realized, and the rice transplanter can be driven automatically.

Description

technical field [0001] The invention belongs to the technical field of agricultural control, in particular to an automatic control system of 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. The accuracy of the machine has a great impact, and it is easy to produce defects such as repeated rows and missing rows, resulting in reduced production; at the same time, the rice transplanter can only perform the transplanting operation, and fertilization after the transplanting is completed, and it is impossible to fertilize while transplanting the rice seedlings, and the work efficiency is low. Contents of the invention [0003] Aiming at the defects in the prior art, the purpose of the present invention is ...

Problems solved by technology

[0003] Aiming at the defects in the prior art, the purpose of the present invention is to solve the technical problem that the rice transplanter in the prior art cannot drive automatically. The present invention proposes an automatic control system and control method for the unmanned rice transplanter. The present invention can realize rice transplanting Simultaneous operation with fertilization, the rice transplanter can be driven automatically, and the amount of fertilizer discharge can be adjusted to ensure the uniformity of fertilization and high work efficiency
