Automatic satellite finding method and satellite finding device

Abstract

The invention discloses an automatic satellite finding method and a satellite finding device. The automatic satellite finding method includes utilizing a DisEqc command controller (1) in the automatic satellite finding device as an information processing and controlling core to control rotating of an antenna motor, acquiring satellite signals that the rotating position of the motor corresponds to from a signal wire connected with a low noise bock (LNB) through a signal strength reading module (2) and measuring and calculating strength of the signals and judging whether the signal strength is the optimum signal strength or not to achieve automatic satellite finding. In addition, a shock sensor (4) and a gravity sensor (5) are further used in the automatic satellite finding process to acquire rotating state and rotating angle of the motor and feed back the information to a set top box for display in real time through a wireless transmitting and receiving module (7 and 8), so that the set top box can efficiently and sensitively control the antenna motor. The method and the device further have the advantages that the set top box can automatically find a plurality of target satellites by sending a satellite finding command only once.

Description

technical field [0001] The invention relates to a satellite-finding technology for a digital TV satellite, and more specifically, relates to an automatic star-seeking method and a star-finding device. Background technique [0002] For digital satellite TV users, it is very important to accurately and conveniently find out the satellite signal to be received. Below the DiSEqC 1.3 protocol, commands are transmitted one-way in the coaxial cable to control the rotation of the antenna motor that receives satellite signals. Although the DiSEqC 2.0 protocol has the function of bidirectional control, the price is too high. The existing technology based on the DiSEqC 1.3 protocol adds some current or voltage detection devices at the source of the set-top box transmission command, so as to detect the rotation of the satellite antenna to control the motor to turn or stop, so as to realize automatic satellite search, but this The automatic satellite finding method has very low efficien...

Below the DiSEqC 1.3 protocol, commands are transmitted one-way in the coaxial cable to control the rotation of the antenna motor that receives satellite signals. Although the DiSEqC 2.0 protocol has the function of bidirectional control, the price is too high

The existing technology based on the DiSEqC 1.3 protocol adds some current or voltage detection devices at the source of the set-top box transmission command, so as to detect the rotation of the satellite antenna to control the motor to turn or stop, so as to realize automatic satellite search, but this The automatic satellite finding method is very inefficient and has poor sensitivity. It can only find one satellite at a time, which cannot achieve the purpose of automatically finding all the satellites in this half-day when the set-top box starts a star-seeking command.

In addition, these technologies need to modify the hardware of the set-top box, which does not conform to the principle of ease of use, and cannot conveniently upgrade the existing set-top boxes.
