Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0012] Such as figure 1 As shown, the present invention includes two satellite antennas 1 , two low noise amplifiers 2 , a switching unit 3 , an intermediate frequency processing device 4 , a local area network 5 and two power amplifiers 6 . The two satellite antennas 1 transmit the signal of the heading of the ship to their corresponding low-noise amplifiers 2, amplify the data information and perform logic operations through the switching unit 3, and the information after the operation is converted from analog signals to digital by intermediate frequency processing equipment 4 signal, and then transmit the digital signal to the local area network 5 for use. After the command control digital signal in the local area network 5 passes through the intermediate frequency processing device 4 and converts it into an analog signal, it is transmitted to two...

Abstract

The invention relates to a double tracking satellite antenna system and a using method thereof. The double tracking satellite antenna system comprises two satellite antennae, two low noise amplifiers, a switching unit, medium frequency processing equipment, a local area network and two power amplifiers, wherein the two satellite antennae transmit signals to respectively corresponding low noise amplifiers which are connected with the medium frequency processing equipment through the switching unit so as to convert analog signals to digital signals which are then transmitted to the local area network; command control signals in the local area network are converted into analog signals through the medium frequency processing equipment; and the analog signals are respectively transmitted to the two power amplifiers through the switching unit, and are amplified and then transmitted to the respectively corresponding satellite antennae. Ship heading data is acquired from a gyrocompass of a drilling ship through the switching unit, and is subjected to logic operation; the switching work of the two satellite antennae is realized through a relay switch; therefore, the performance of automatic switching is realized. The double tracking satellite antenna system can be widely applied in the field of exploration and exploitation of multiple kinds of oil.

Description

technical field [0001] The invention relates to a satellite communication system, in particular to a dual tracking satellite antenna system installed on a deep-water semi-submersible drilling ship in the offshore oil exploration and development process and its application method. Background technique [0002] In the process of offshore oil exploration and development, the heading of traditional drilling ships does not move. Before anchoring each time, calculations must be made based on the position of the satellite and the location of the drilling ship to avoid blocking the communication lines by the drilling derrick. The traditional switching device for automatic switching between two satellite communication antennas will cause the satellite communication to be interrupted when the heading of the drilling ship is changed, so that the switching device cannot work normally. Contents of the invention [0003] In view of the above problems, the object of the present invention...
