Embodiment Construction

[0030] The technical solution in this application will be described below with reference to the accompanying drawings.

[0031] figure 1 It is a schematic diagram of a satellite signal ground receiving system using a method for satellite switching of a motor antenna and a control device of the present application. Such as figure 1 As shown, the satellite signal ground receiving system 100 includes a receiving antenna 110 , a user receiver 120 and a television set 130 . The receiving antenna 110 includes a receiving antenna, a feed source, a tuner and a motor. The antenna receives satellite signals and transmits the signal to the feed source. The feed source converts the received microwave signal into an electrical signal and sends it to the tuner. The tuner Also known as a low-noise block downconverter (LNB), the satellite signal sent by the antenna 110 is down-converted and the signal is amplified and sent to the user receiver 120, and the user receiver 120 receives the wea...

Abstract

The invention provides a method, control device and system for performing satellite switching on a motor antenna, which can reduce the time spent by the motor for rotating to a preset position when switching different satellite programs. The method comprises the steps of determining that a current channel and a target channel correspond to satellites with different longitudes according to the readsatellite longitude of the target channel; determining that the polarization mode of satellite launching radio waves for transmitting a target channel signal is first polarization according to a channel polarization mode in parameters of the target channel, and controlling the power supply of the motor according to power supply voltage of a second polarization mode of the antenna, wherein the power supply voltage of the second polarization mode of the antenna is higher than the power supply voltage of the first polarization mode of the antenna; sending a rotation instruction to the motor; andcontrolling the antenna to receive signals according to the first polarization mode when the motor is determined to rotate to the preset position.

Description

technical field [0001] The present application relates to the communication field, and more particularly, to a method, control device and system for performing satellite switching on a motor antenna. Background technique [0002] In Europe, America, and African countries, users watch TV through satellites. There are often several TV operators in these countries and regions, and each TV operator has its own exclusive channel. At the same time, the proprietary channels of these TV operators are distributed on satellites in different orbits. The most direct way for users to watch different channels is to install Digital Satellite Equpipment Control (DiSEqC) motor antennas, motor antennas It takes a certain amount of time to switch between different satellite orbits, resulting in a long waiting time for the set-top box to change channels, which affects user experience. [0003] Therefore, how to reduce the time required for the motor to rotate to the preset position when switch...
