A method and system for realizing intelligent switching of dual GPS 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 and system for implementing intelligent switching of dual GPS antennas. 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. The antennas are circularly polarized antennas with good upper hemispheric efficiency. , Because all GPS satellites are high in the sky, the upward gain of the antenna pattern is very good to improve 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, but the gain in the downward direction will be poor. This point is very advantageous for many devices with a fixed design, because we can deliberately make the device's GPS antenna pattern upward when installing the device. However, this design is v...
