Simple and convenient satellite search method based on automatic identification of relevant parameters of high-frequency head

Abstract

The invention discloses a simple and convenient satellite search method based on automatic identification of relevant parameters of a high-frequency head. The method comprises the following steps of acquiring degrees of an azimuth angle and an elevation of a satellite receiving pot, positioning information of a set top box and a local oscillation frequency of the high-frequency head, and sending the acquired degrees of the azimuth angle and the elevation, the positioning information and the local oscillator frequency to a control and data recording module; prearranging parameter information ofeach satellite in the control and data recording module, making the control and data recording module generate chain table information of each satellite according to the acquired local oscillator frequency and send the generated linked list information to the set top box, selecting and confirming the satellite information by a user through the set top box, and feeding back the satellite information to the control and data recording module. According to the method, the azimuth angle and the elevation of the satellite receiving pot can be quickly acquired, the local oscillator frequency of thehigh-frequency head can be acquired, and a situation that the high-frequency head cannot be used when a high-frequency head identification is lost is avoided.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a simple and convenient satellite search method based on automatic identification of high-frequency head related parameters. 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 ...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a simple satellite search method based on automatic identification of the relevant parameters of the tuner, which solves the problem that the existing satellite communication cannot automatically identify the specific parameters of the tuner, and can quickly obtain satellite reception. The azimuth and elevation angle of the pot can obtain the local oscillator frequency of the tuner, so as to prevent the tuner from being unusable when the mark of the tuner is lost
