Wherein said trigger module comprise a remote controller and receive remote controller signal and with the infrared remote receiver of remote controller signal input controller; Described remote controller definition has one to show the satellite signal quality button and show satellite-signal intensity button.
Compared with prior art, the utlity model has following beneficial effect: the utility model shows to drive display module by the quality information input driver module of controller with satellite-signal, make the user to star the time, only need carry set-top box, observe the satellite signal quality information that display module demonstrates on the set-top box, regulate antenna, and need not the observation television machine, as seen, the utility model greatly facilitates the user to star.
Description of drawings
Fig. 1 is the schematic diagram of embodiment 1 of the present utility model;
Fig. 2 is the schematic diagram of remote controller of the present utility model;
Fig. 3 is the display effect schematic diagram of demonstration satellite signal quality information of the present utility model;
Fig. 4 is the schematic diagram of embodiment 2 of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The utility model mainly is to show to drive display module by the quality information input driver module of controller with satellite-signal, make the user to star the time, only need carry set-top box, observe the satellite signal quality information that display module demonstrates on the set-top box, regulate antenna.
For economizing on resources, display module of the present utility model preferably adopts the existing front panel display module of set-top box, generally can be LED display or VFD display screen.Driver module also is the existing front panel driver module of set-top box.Also increase by a trigger module in addition, make display module when other information such as indicated channel, switch to demonstration satellite signal quality information.
Embodiment 1
As shown in Figure 1, the operation principle of present embodiment is: after antenna receives satellite-signal, obtain through tuner, be transferred to controller again, by controller to the satellite-signal transmission of decoding, transfer to driver module after wherein satellite signal quality information sent the order that shows satellite signal quality information at trigger module, trigger module preferably adopts the infrared remote receiver of remote controller and reception remote signal in the present embodiment, as shown in Figure 2, at first definition one red button 11 is expressed as the demonstration satellite signal quality on remote controller 10, when the user presses this redness button 11, after infrared remote receiver receives infrared remote-controlled signal, transfer to controller, its middle controller preferably adopts CPU, after CPU identification, the quality information of satellite-signal is exported by the RS232 interface bus of CPU, because the RS232 interface bus has only two lines, the line number is not enough for driver module, so, on the RS232 interface bus, connect a bite line expansion module, be preferably single-chip microcomputer, be used for the expansion bus width, be connected to driver module then, make driver module produce drive signal, make display module demonstrate the quality information of satellite-signal, as shown in Figure 3.
The user is during to star, after set-top box is powered on, presses red button 11, display module 20 is for demonstrating the quality information of satellite-signal, and the user regulates antenna, when display module 20 shown quality information numerical value are maximum, the expression aerial position is correct, promptly finishes star is operated.
In addition, for making set-top box functionality more comprehensively, increased the function that makes display module 20 demonstrate satellite-signal intensity, specifically, on remote controller 10, define a green button 12 again and be expressed as demonstration satellite-signal intensity, when the user presses 12 li of green buttons, after infrared remote receiver receives remote signal, transfer to controller, after the via controller identification, the strength information of satellite-signal is reached driver module, show by display module 20 again, in general, as long as the set-top box power supply is normal, the strength information of satellite-signal is just normal.
