Abstract

The invention discloses a parcel area measuring device and method based on Beidou positioning. The parcel area measuring device comprises a Beidou signal receiving module, a singlechip module, an interactive touch screen module and a power supply module. The Beidou signal receiving module is used for receiving information sent by Beidou satellites, the power supply module provides stable voltagesfor power supply interfaces of the Beidou signal receiving module, a singlechip and a voice broadcasting module through voltage conversion modules, an interactive touch screen displays current coordinate points in real time, the coordinate points with obvious errors can be corrected through the screen, and the unit price of the operation can be input through the interactive touch screen for pricing in a pricing mode. The singlechip receives the longitude and latitude data sent by the Beidou signal receiving module in real time and filters the data to obtain more accurate longitude and latitudedata. When an area is measured, the singlechip directly outputs a result to the interactive touch screen for display. In the pricing mode, in addition to displaying the measured area, the unit priceinformation input by the screen is received, and the unit price multiplies the area and then the pricing result is displayed on the screen.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to an area measuring instrument, in particular to a device and method for measuring land area based on Beidou positioning. Background technique [0002] When working on various plots, the working area is a key data. Such as green area measurement, lawn maintenance pricing, farmland operation area measurement and pricing, etc., generally, it is usually roughly estimated based on empirical data, or manually measured and calculated with a meter ruler. However, in the case of irregular shapes or high data accuracy requirements, manual measurement is time-consuming and laborious, and it is difficult to achieve the required accuracy. [0003] At present, the common area measurement devices on the market are mainly used for area measurement and valuation of farmland. For example, CN101672639A, an invention patent authorized and published on March 17, 2010, discloses a GPS-based farmlan...
