Real-time acre counting method based on GPS (Global Positioning System)

The invention discloses a real-time acre counting method based on PGS (Global Positioning System), which comprises the following steps: mounting a universal GPS module and an embedded control system on a harvester; calculating the longitude and the latitude of the position of the harvester during the harvesting process of the harvester in real time through the GPS module; calculating the advance distance of the harvester according to the longitudes and the latitudes of two adjacent positions of the harvester calculated by the GPS module through the embedded control system; and multiplying the calculated advance distance with the cutting amplitude of the harvester to obtain the harvesting area between the two calculation positions of the harvester. The method of the invention precisely counts the working area of the agricultural harvesting machinery through GPS signals in real time. The method is simple and effective, and the method can perform real-time acre counting on the harvester during the working process of the harvester without changing the current harvesting machinery.
