Description

Technical Field

[0001] The utility model belongs to the technical field of cultivated land area measurement, and more specifically, particularly relates to a measurement and statistics device for cultivated land area changes. Background Art

[0002] The method of measuring the cultivated land area is often used to supervise the illegal occupation of cultivated land. The cultivated land measurement and statistical device is used to measure the excess cultivated land area. When measuring and counting the cultivated land area, an acre meter is generally used to measure the cultivated land area. When measuring, the surveyor needs to hold the acre meter and walk around the measured cultivated land for a week, and then automatically calculate the area of ​​the cultivated land through the GPS of the acre meter.

[0003] The existing application number is: CN201920757696.0. The utility model discloses a wheeled distance measuring and acre measuring instrument. When in use, the acre measuring instrument is turned on by the control button 2, and the ephemeris download is waited for 1-2 minutes until it is basically stable. The wheeled distance measuring and acre measuring instrument is pushed to walk around the land to be measured. The shape and outline of the land are drawn on the display screen 1 through GPS positioning. The electronic counter 5 converts the distance by counting the rotation of the distance measuring wheel 4. The distance data of the wheeled distance measurement is combined with the direction data of the GPS for correction to obtain a more accurate land area. The device compensates for the error of GPS through wheeled distance measurement, so that the measurement result is more accurate, and the data can be directly viewed through the touch screen, which is simple and easy to use.

[0004] Based on the above, when using an acre meter to measure the area of ​​arable land, the inspection personnel are required to walk around the arable land. Since the inspection personnel need to return to the initial position after walking around, it is generally necessary to mark the initial position. When marking the initial position, the inspection personnel generally draw a line at the initial position and then perform the measurement operation. The operation is relatively cumbersome, which affects the measurement efficiency of the arable land area. Utility Model Content
