Implementation method and system of intelligent switching of double GPS (Global Positioning System) antennas

Abstract

The invention provides an implementation method and system of the intelligent switching of double GPS (Global Positioning System) antennas. The implementation method comprises the following steps: obtaining a space position coordinate collected by a gravity sensor in equipment; judging whether the space position coordinate is positioned in a preset space position coordinate range or not, and controlling a radio frequency switch connected with a GPS module to be connected with a first GPS antenna if the space position coordinate is positioned in the preset space position coordinate range; otherwise, controlling the radio frequency switch connected with the GPS module to be connected with a second GPS antenna. Since the first GPS antenna and the second GPS antenna are oppositely arranged in the equipment in a back-to-back way in the method and system, the preset space position coordinate range corresponds to the equipment space position and is specifically that the first GPS antenna is positioned above the second GPS antenna, so that a video switch can switch the GPS antenna automatically according to the obtained space position information so as to realize GPS omnibearing position positioning, and convenience is brought for obtaining accurate position data.

Description

technical field [0001] The invention relates to the technical field of intelligent positioning, in particular to a method for realizing intelligent switching of dual GPS antennas and a system thereof. Background technique [0002] At present, the Global Positioning System (GPS) antennas in various positioning devices are basically passive, and most of them are designed with ceramic antennas. This antenna is a circularly polarized antenna with good upper hemisphere efficiency. , because all GPS satellites are in the high altitude, the high gain of the antenna's pattern is good for improving the GPS performance. [0003] The advantage of the ceramic antenna is that it has strong directivity. Generally, its gain in the upward direction is better, and the gain in the downward direction will be poor. This is very advantageous for many devices with a fixed position design, because we can deliberately make the GPS antenna pattern of the device face upward when installing the devic...
