Embodiment Construction

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] The GPS-based farmland operation area measurement system of the present invention adopts a general GPS positioning system and a single-chip microcomputer, and aims at the problem of low GPS positioning accuracy and the regular shape of the general farmland. After running the operation measurement area for one week, after automatically recording the coordinates of the operation route, the obtained farmland operation route is trimmed, and the fixed point coordinates are converted, and then the surrounding area is calculated.

[0020] like figure 1 As shown, the GPS-based farmland operation area measurement system of the present invention includes a GPS receiving module, a single-chip computer, a memory, a keyboard, an LCD display, a printer, a power supply, and the like. The GPS receiver module adopts UP500 GPS receiver, which int...

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...
