Abstract

The control device includes control box, and antenna platform. The control box includes CPU, signal interface board, sensor of signal intensity, unit of measuring antenna position, and unit for controlling antenna pointing, which are connected to each other through RS 485 bus. The antenna platform includes following parts: electric gyrocompass connected to RS485 bus and unit of measuring antenna position, optic fiber gyroscope, elevation sensor, receiver of satellite antenna, which through coaxial line is connected to sensor of signal intensity in control box, and step motor controlled by the control box. A GPS signal receiving board is added in order to ensure uninterrupted received signal. Electric map software about way of this train is installed to CPU in order to get clear relevant images.

Description

Technical field [0001] The invention relates to satellite communication and positioning technology, in particular to a mobile satellite automatic tracking control device. Background technique [0002] New technologies such as satellite TV and high-fidelity stereo broadcasting have made modern trains a digital intelligent train integrating business office, leisure and entertainment, security monitoring, and information management services. However, existing satellite tracking control devices still accept TV. The program is not clear enough, and when the train passes through blind areas such as tunnels, the video cannot be automatically switched to play, resulting in interruption of viewing. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a mobile satellite automatic tracking control device. [0004] The technical scheme of the present invention is: composed of a control box and an antenna platform...
