Embodiment Construction

[0037] The present invention will be described in further detail below by means of the accompanying drawings. The small and medium scale farmland in the present invention has a rectangular shape with a width of 200 m and a length of 100 to 200 m. * in the present invention represents multiplication sign

[0038] The agricultural machinery navigation system applied to small and medium-sized farmlands of the present invention includes: a field target 1, a distance measuring device, a display device and a vehicle-mounted computer, wherein: the distance measuring device, the display device and the vehicle-mounted computer are all arranged on the agricultural machinery, and the distance measuring device The measured distance between the ranging equipment and the target is the distance between the agricultural machinery and the target.

[0039] The field target is set in a corner of the farmland, and the field target includes A target and B target, which are used to provide identif...

Abstract

The invention discloses an agricultural machine navigation system and method applied to small and medium-sized farmland. The navigation system comprises a distance measurement device, an intelligent camera, a vehicle-mounted computer, a farmland target and a display device. According to the navigation system, the distance between an agricultural machine and the farmland target is obtained through the distance measurement device, distance information is converted into the information of the actual position of the agricultural machine and the relative position of a preset rail through the vehicle-mounted computer, the information is sent to the display device at last, an agricultural machine operator can observe the relative position of the agricultural machine in real time through the display device, and the agricultural machine is controlled to return to the preset position if deviating from the preset rail. The agricultural machine navigation system has the advantages of being simple in structure, higher in maintainability, lower in failure rate, low in cost and the like.

Description

technical field [0001] The invention relates to an agricultural machinery navigation device, in particular to an agricultural machinery navigation system and navigation method applied to small and medium scale farmland. Background technique [0002] my country is a large agricultural country. Although the level of agricultural mechanization in my country has improved in recent years, it is still relatively low compared to the level of intelligence. In mechanical farming, the operator's experience is often used to improve the quality of farming, which not only puts forward higher requirements for the operator but also increases its labor intensity. Therefore, the use of the agricultural machinery field operation navigation device can improve the cultivation quality and reduce the operator's work intensity. [0003] The navigation of agricultural machinery can be defined as determining the size of the steering angle of the vehicle according to the error between the actual pos...
