System and method based on GPS for measuring farmland working area

Abstract

The invention relates to a system based on GRS for measuring working areas. The system comprises a GPS receiving module, a single chip computer, a memory, a keyboard, a display, a printer and a powersupply, wherein the GPS module receives a GPS satellite signal and inputs positioning information into the single chip computer by an RS232 serial port; the single chip computer processes the positioning information and calculates the area of the farmland; the memory stores a working record; by the keyboard and the display, the working fee-charging unit price is input, the date is set, the workingroute is trimmed, the working area is calculated, and the working record is searched; and the minitype printer prints and outputs the working record. The invention adopts a GPS positioning system tomeasure the working area of the original farmland, adopts the single chip computer to trim the working area of the original farmland and enhances the measurement accuracy of the working area of the farmland.

Description

technical field [0001] The invention relates to a GPS-based farmland operation area measurement system and a measurement method, belonging to the technical field of agricultural machinery testing, and is mainly used for agricultural machinery farmland operation area measurement to realize valuation and management of farmland operations. Background technique [0002] The cross-regional operation of agricultural machinery such as combine harvesters is a form of farmland production operation suitable for my country's national conditions. For off-site operations, both operators and farmers want to know the area and output of actual farmland operations. Configuring area or output pricing system is an inevitable trend in the development of agricultural machinery. There is no time to delay. [0003] At present, there are two main methods for real-time detection of agricultural machinery operating area: one is to use the area measuring instrument or meter developed by the GPS positio...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the above-mentioned deficiencies, and disclose a GPS-based farmland operating area measurement system and measurement method, which is characterized in that: a general GPS positioning system and a single-chip microcomputer are used to solve the problem of low GPS positioning accuracy and the regular shape of general farmland , by presetting or selecting the shape of the farmland, after going around the operation measurement area for a week, automatically recording the coordinates of the operation route, trimming the obtained farmland operation route, and converting the coordinates of the fixed point, and then calculating the surrounding area , so as to improve the measurement accuracy of farmland operation area
