Automatic star alignment device based on the front panel display of the receiving decoder

Abstract

The invention discloses an automatic satellite-aligning device based on front panel display of a receive decoder. The automatic satellite-aligning device comprises a remote control receiving module, a pulse width modulating module and a front panel data analyzing module, wherein the remote control receiving module is used for analyzing remote keys and realizing functions of starting and exiting of satellite alignment states; the pulse width modulating module produces waveform to control the rotation of an antenna; the front panel data analyzing module is used for detecting the quality of satellite signals displayed by a front panel of the integrated receive decoder of a satellite live system in real time and controlling the operation of the antenna in real time according to the detection result; the remote receiving module is connected with the pulse width modulating module; the pulse width modulating module is connected with the front panel data analyzing module. When the automatic panel-displayed satellite-aligning device is used, a user presses down a key of a remote controller, the automatic satellite-aligning device can be automatically controlled indoors, the direction of a satellite receive antenna is automatically adjusted so as to make the antenna at a best position, and therefore, the mounting efficiency of the satellite receive antenna of the integrated receive decoder of the satellite live system is further improved.

Description

technical field [0001] The invention relates to the technical field of digital television reception, in particular to an automatic satellite alignment device for a comprehensive receiving decoder of a satellite live broadcast system. Background technique [0002] With the development of the live broadcast satellite "every household communication" work, the comprehensive receiver decoder of the satellite live broadcast system has gradually entered thousands of households. [0003] However, the satellite alignment work of the integrated receiving decoder of the existing satellite live broadcast system is also relatively complicated. During the debugging process, it is only possible to estimate a rough position, and then manually turn the pot antenna slowly to perform alignment. The operation is relatively slow. Moreover, it is relatively troublesome to monitor the signal strength and quality of the TV display at the same time during the star alignment process. Generally, only...
