Beidou navigation unmanned full-hydraulic multifunctional tractor and control method thereof

Abstract

The invention discloses a Beidou navigation unmanned full-hydraulic tractor and a control method thereof, comprising a tractor body, a hydraulic system, a sensor integration system, a control system and a Beidou GPS navigation system. A Beidou navigation unmanned full-hydraulic multifunctional tractor, which has multiple functions such as deep plowing, subsoiling, planting, fertilization, land leveling, field management, etc., overcomes the single-function defect of existing agricultural tractors, and its control method realizes It can walk, avoid obstacles, turn, and operate autonomously in different terrains and landforms 24 hours a day.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a Beidou navigation unmanned full-hydraulic multifunctional tractor and a control method thereof. Background technique [0002] Tractors are currently the most widely used agricultural machinery. Due to the influence of terrain factors, it is difficult to popularize large-scale agricultural equipment in many hilly areas in the south. Traditional tractors are manually operated and wheeled, and have high requirements for roads and farmland. After the rain, it is almost difficult to work, and it is difficult for artificial machines to walk straight and evenly, which affects the uniformity and quantity of sowing, increases the wind resistance of crops, and makes crops prone to lodging, thus affecting the yield. [0003] With the rise of the wave of farmers going out to work, farmers' friends have put forward new requirements for traditional farming methods. They neede...

Problems solved by technology

In addition to the characteristics of the above-mentioned walk-behind tillage machine, the remote-control tiller abandons the shortcomings of the walk-behind tiller, which are labor-intensive, poor in sustainable production capacity, and greatly affected by environmental factors.

[0004] At present, there are also some reports on the structure of unmanned agricultural machinery, but these mechanical structures generally have shortcomings such as complex structure, high manufacturing cost, small use range, and high use requirements. In order to improve these problems, China's "Agricultural Unmanned Tiller" application No.: 201420053908.4, announced an agricultural unmanned tiller. Each control function on the tiller has a corresponding motor and an electric push rod to realize the corresponding operation action. All electric push rods can be realized by the remote control. function, so as to realize the remote control of the cultivator, but there is no corresponding function in avoiding obstacles, and it is difficult to achieve accurate navigation and traction through manual remote control, and it can only be used during the day

[0005] In order to improve the accuracy of operation and improve the utilization rate of the machine, the application number of the Chinese patent "An Electric Control System for Unmanned Tractors" is: 201220718117.X, and it is announced that it uses the combination of DGPS navigation and electronic maps to automatically plan a reasonable driving The electronic control system of the unmanned tractor in the path can realize continuous operation day and night, freeing the agricultural machine driver from monotonous and repetitive work, and the agricultural machine user can operate multiple unmanned tractors at the same time, which improves production efficiency. The control accuracy is not high, it is difficult to be practical, and there is no explanation on how to transform the tractor
