Method, system and terminal for positioning working machine in greenhouse

Abstract

The invention discloses a method, a system and a terminal for positioning a working machine in a greenhouse. The method comprises the steps of determining relative position information of each of a first base station, a second base station and a third base station, and a label arranged on the working machine; determining an X axis and a Y axis according to a moving range edge line of the working machine so as to determine an electronic coordinate system; and according to determined coordinate positions of the first base station, the second base station and the third base station in the electronic coordinate system and the relative position information of each base station and the label, determining the position of the working machine in the greenhouse. The three base stations are arranged;the relative position information between each base station and the label arranged on the working machine is determined; and the coordinates of each base station in the coordinate system and the actual position of each base station in the greenhouse are determined, so that the accurate position of the working machine in the greenhouse can be determined. The communication between each base stationand the label is performed by an ultra-wideband pulse; and the ultra-wideband pulse has an extremely strong penetration capability, and the positioning precision can reach the centimeter level, so that the positioning accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of greenhouse machine tool positioning, and in particular to a method, system and terminal for working machine tool positioning in a greenhouse. Background technique [0002] my country is the country with the largest greenhouse area in the world, and it is also a major producer and consumer of agricultural products. Constrained by factors such as poor matching of facilities and equipment and the overall low level of equipment manufacturing, my country's facility gardening equipment is comparable to developed countries in terms of operating efficiency and intelligence level. There is a large gap, especially the lack of a high-precision positioning system for working tools in the greenhouse. [0003] For the system, indoor positioning is an indispensable key technology. For the indoor positioning of the greenhouse, the positioning accuracy needs to reach the centimeter level. Traditional positioning ...

Problems solved by technology

[0002] my country is the country with the largest greenhouse area in the world, and it is also a major producer and consumer of agricultural products. Constrained by factors such as poor matching of facilities and equipment and the overall low level of equipment manufacturing, my country's facility gardening equipment is comparable to developed countries in terms of operating efficiency and intelligence level. There is a big gap, especially the lack of high-precision positioning system for working tools in the greenhouse

[0003] For the system, indoor positioning is an indispensable key technology. For the indoor positioning of the greenhouse, the positioning accuracy needs to reach the centimeter level. Traditional positioning methods such as GPS (Global Positioning System, global positioning system), infrared, Positioning accuracy such as Bluetooth cannot meet the requirements of operating accuracy in the greenhouse, so it is difficult to apply it to obtain the position of operating tools in the greenhouse
