Simple satellite searching device based on automatic identification for relevant parameters of tuner

Abstract

The invention discloses a simple satellite searching device based on automatic identification for relevant parameters of a tuner, which comprises a satellite receiving pot, a tuner and a set-top box,and is characterized by further comprising a satellite receiving pot angle and elevation degree sensor, a tuner local oscillation detection module and a positioning module, wherein the satellite receiving pot angle and elevation degree sensor is used for detecting the azimuth angle and elevation degree of the satellite receiving pot and feeding back the detected data to a control and data recording module; the tuner local oscillation detection module is used for detecting the local oscillation frequency of the tuner and feeding back the detected data to the control and data recording module; and the positioning module is used for acquiring real-time positioning information of the set-top box. The simple satellite searching device can quickly acquire the azimuth angle and elevation of the satellite receiving pot and can acquire the local oscillation frequency of the tuner, thereby avoiding a circumstance that the tuner cannot be used when the identification of the tuner is lost.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a simple and convenient satellite search device based on automatic identification of relevant parameters of a tuner. Background technique [0002] The tuner is a microwave signal receiving device whose main function is to receive high-frequency signals and convert the high-frequency signals. Then the intermediate frequency signal after frequency conversion is transmitted to the set-top box for digitization of the intermediate frequency signal, and then transmitted to the TV. Many times, the tuner can accept many satellites. As long as the signal transmitted by the satellite is within the receiving range of the high frequency. The set-top box needs to set relevant parameters according to the specific parameters of the relevant satellites. [0003] During the existing high-frequency debugging, the corresponding satellite parameters and the local latitude will be ...
