Abstract

The invention relates to the technical field of land planning, in particular to a portable land area measuring instrument for land planning design, which comprises a fixed frame, roller mounting rods are symmetrically and rotatably mounted on two side walls of an inner cavity of the fixed frame, and fixed rods are fixedly mounted at one ends, far away from the fixed frame, of the two groups of roller mounting rods on the left side. Adjusting rods are rotatably mounted at the two ends of the fixing rod correspondingly, rotating rollers are rotatably mounted at the ends, away from the fixing rod, of the two adjusting rods correspondingly, a first traction rod is rotatably mounted on the right side between the two rotating rollers, and a steering mechanism is arranged on one side of each adjusting rod. Wheel shafts are rotationally mounted at the ends, away from the fixed frame, of the two groups of roller mounting rods on the right side. Compared with the prior art, the problem that a traditional land area measuring instrument only carries out area measurement calculation according to the longitude and the latitude, and the measurement error is large when the land with the gradient is handled is solved.

Description

technical field [0001] The invention relates to the technical field of land planning, in particular to a portable land area measuring instrument for land planning and design. Background technique [0002] The land area measuring instrument is a field area measuring instrument developed by advanced technologies such as GPS positioning system and embedded single-chip microcomputer. It can quickly measure and map the area, distance, perimeter and other data of land of any shape. It is suitable for farmland, green space, forest, water area It provides a convenient measurement tool for agriculture, forestry, water conservancy, soil management, taxation and other departments and agricultural machinery operation charges. [0003] Traditional land area measuring instruments only measure and calculate the area based on longitude and latitude. The measurement results are more accurate when facing flat land, but the measurement error is larger when dealing with sloped land. Contents ...
