Problems solved by technology

This algorithm can effectively solve the problem of re-cultivation, but the calculation accuracy is greatly affected by the selection of the grid side length, and when the trajectory is scattered and the operating range is large, the calculation amount is too large, and the algorithm efficiency is low

Embodiment Construction

[0018] See attached figure 1 , the agricultural machinery collects position information every 2 seconds during the driving process, and each position information has an identification of the working status. The trajectory of agricultural machinery movement can be obtained through the collection of location information. The location information includes at least coordinates of the location, receiving time, and job attributes.

[0019] The invention provides a method for judging the repeated operation area of ​​agricultural machinery based on spatial analysis, which includes three steps: step A, step B and step C.

[0020] Wherein, in step A, land parcel identification is performed according to the location information collected during the driving of the agricultural machinery.

[0021] Specifically, step A1, collecting the position information collected during the driving of the agricultural machine, deleting the unworked position points in the motion trajectory and setting t...

Abstract

The invention discloses an agricultural machinery repeated operation area judgement method based on space analysis, and belongs to the technical field of agricultural machinery. The method includes the following steps that A, plot recognition is carried out according to information acquired by the agricultural machinery in the driving process; B, the boundary of a plot is recognized, and the areaof the plot is calculated; C, repeated operation is judged; wherein in the step C, C1, longitude and latitude positions of coordinates of the center point of the plot are encoded through Geohash encoding based on a dichotomy approximation principle, and C2, repeated operation calculation is carried out. By the adoption of a plot encoding mode, the screening range is narrowed, the operand of distance conversion between the longitude and latitude is reduced, and the purpose of rapidly and accurately calculating the repeated operation area is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a method for judging the repeated operation area of ​​agricultural machinery based on spatial analysis. Background technique [0002] With the rise of labor costs and the expansion of agricultural operations under land transfer, the urgent demand for mechanization and even mechanized operation services in agricultural production has become increasingly prominent. The operating area is the core indicator of planting and production, and it is the basis for the settlement of expenses between the supply and demand sides under the background of agricultural machinery market services. In addition, the operating area is also the basis for the settlement of agricultural policy subsidies. Especially in recent years, with the rapid development of agricultural machinery supervision methods and the agricultural market system, traditional agricultural machinery purchase subsidi...
