Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment shells, in particular to a farmland RTK base station box. Background Art

[0002] RTK (Real Time Kinematic) is the abbreviation of real-time dynamic carrier phase differential technology, which is based on the timely processing of the carrier phase of two measuring stations. When conducting RTK measurement, the base station sends the carrier observation value and the base station coordinates to the working mobile station in time through the data link. The mobile station receives the carrier phase from the satellite and the base station at the same time, and gives the centimeter-level positioning results in real time after differential processing. The positioning system using RTK technology has high operating efficiency. High-quality station setting can cover a measurement area with a radius of 5-10km at a time, and the positioning accuracy can reach the centimeter level without cumulative errors.

[0003] We have developed an RTK base station box for farmland to obtain RTK high-definition positioning data and transmit the data to agricultural machinery through radio frequency antennas. The base station is equipped with a high-frequency antenna, with a coverage range of 30-50 kilometers, achieving all-round transmission range coverage without blind spots. And through the management background, a national agricultural base station network is built, so that agricultural machinery can be free from network restrictions and can independently cultivate and harvest in areas such as mountains, forests and hills.

[0004] The wires of the existing RTK base station box are exposed to the outside, which is easy to get wet in rainy weather, causing leakage and short circuit, and the structure is relatively complicated. Utility Model Content
