GPS equipment for topographic survey

Abstract

The invention discloses GPS equipment for topographic survey, and relates to the technical field of GPS equipment. The GPS equipment for topographic survey comprises a box body, a handle is rotatably installed in the center of the top of the box body, a closing plate is movably installed in the center of the front face of the box body, an anti-falling mechanism is arranged on the inner side of the box body, a moisture removal mechanism is arranged on the inner side of the box body, and the anti-falling mechanism comprises partition plates, ventilation holes, elastic pieces, a storage box and a limiting block. The partition plates are fixedly installed on the inner sides of the top and the bottom of the box body, the ventilation holes are formed in the left side and the right side of each partition plate, and the elastic pieces are fixedly installed on the inner sides of the top and the bottom of the box body. According to the GPS equipment for topographic survey, the anti-falling mechanism is arranged to be matched with a dehumidification mechanism, so that the GPS equipment is prevented from being collided and damaged due to road bumping in the topographic survey process, and the situation that the equipment is damaged due to the fact that water enters the box body to be affected with damp and moisture enters the equipment in rainy days, and the measurement precision of topographic survey is affected is avoided.

Description

technical field [0001] The invention relates to the technical field of GPS equipment, in particular to a GPS equipment for terrain surveying. Background technique [0002] GPS equipment (Global Position System) is the global positioning system, which is used to receive and analyze the orbit information and time information in the radio waves returned by several satellites in space to calculate the longitude, latitude, horizontal altitude and movement of the GPS receiver's location Speed, the basic configuration of GPS equipment usually includes a GPS receiver, resolver and a high-efficiency microcomputer. GPS equipment is needed in topographical surveying to detect terrain conditions; After measuring the projected position and elevation of surface features and topography on the horizontal plane, they are scaled down to a certain scale, and then drawn into a topographic map with symbols and annotations. [0003] At present, GPS devices for topographical surveys on the market...

AI Technical Summary

Problems solved by technology

[0003] At present, GPS devices for topographical surveys on the market need to pass through areas with complex terrain conditions when performing topographical surveys. The bumps on the road surface will easily cause the GPS devices to collide with the box wall in the storage box, and in rainy weather, moisture will pass through the box. The outer gap enters the box, and the moisture accumulated in the box will cause damage to the equipment
