Agricultural machinery automatic driving control system based on Beidou navigation and method thereof

Abstract

The invention provides an agricultural machinery automatic driving control system based on Beidou navigation and a method thereof, and belongs to the technical field of agricultural machinery control. The agricultural machinery automatic driving control system comprises a differential reference station, an automatic driving instrument and a visual sensor. The differential reference station comprises a first measurement antenna which is connected with a first measurement receiver. A transmitting radio is connected on the first measurement receiver. The automatic driving instrument comprises a vehicle-mounted navigator, a vehicle-mounted display controller, an electric steering wheel controller and a guide wheel angle sensor. The vehicle-mounted navigator is connected with the vehicle-mounted display controller. The output ports of the electric steering wheel controller and the guide wheel angle sensor are connected with the vehicle-mounted display controller. The vehicle-mounted display controller comprises a graphic processing module. The visual sensor is connected with the graphic processing module. Obstacle avoidance of the agricultural machinery can be guaranteed through control of the guide wheel angle and omitted cultivation of the agricultural machinery can be reduced so that cultivation quality of the agricultural machinery can be enhanced, and the agricultural machinery automatic driving control system can be used for control work of agricultural machinery automatic driving cultivation.

Description

technical field [0001] The invention relates to an automatic driving control system and method, in particular to an agricultural machinery automatic driving control system and method. Background technique [0002] Agriculture is the foundation of the country and is related to the stability of the country's politics and economy. With the development of agriculture in our country, it will gradually transform from a decentralized agricultural production mode to a centralized agriculture. Agricultural mechanization is an important indicator to measure a country's agricultural development. With the continuous advancement of the three rural policies, there is an urgent demand for agricultural mechanization. [0003] Agricultural machinery has a labor efficiency that cannot be compared with manual labor. It not only reduces labor intensity, but also liberates a large part of the labor force, and then engages in other industries. Therefore, the development of agricultural machinery ...

AI Technical Summary

Problems solved by technology

Agricultural machinery is mainly used to complete land cultivation, sowing, harvesting and other operations. Most of the existing agricultural machinery is driven manually. For large-scale fields, the driver needs to drive for a long time and is very prone to fatigue

Moreover, the most important thing is that the use of agricultural machinery is staged, and it is only needed during the time period of plowing, sowing, and harvesting. In this way, drivers who work outside or engage in other industries have to return home during the busy farming season, or It is a large-scale land contractor who does not wait to hire a large number of drivers to carry out farm work during the busy farming season, which will undoubtedly increase the cost of personnel use

[0004] With the maturity of satellite positioning technology (such as my country's Beidou satellite system), communication technology, computer technology and automatic control technology, the location information of the vehicle can be accurately determined according to the received satellite signal, and through the detection and analysis of the current state of the vehicle, Formulate a reasonable automatic driving plan, and have the function of autonomously avoiding obstacles; in the existing technology, when the vehicle encounters an obstacle, the agricultural machine will make a decision based on the surrounding environment whether to start the autonomous lane change mode, after entering the autonomous lane change mode , the vehicle will change lanes independently. This technology can also be used in agricultural machinery, but the operation of agricultural machinery is different from that of ordinary vehicles. It is necessary to consider how to ensure the farming quality of agricultural machinery while avoiding obstacles autonomously. Existing Technology cannot meet the conditions for autonomous driving of agricultural machinery
