Description
Technical field
The utility model relates to a kind of far-end panadaptor control device, refers to a kind of energy-conservation far-end panadaptor control device of tool according to difference signal input state control panadaptor power switch especially.
Background technology
Many now public places, all can use the device of remote image transmission as airport, rapid transit, sales field etc., the far-end receiving trap of its use such as electronic board, TV, display etc., all be connected via a signal transmission line and front end dispensing device such as DVD video player, computer, notebook computer, could make the image signal of described front end dispensing device output be sent on the far-end receiving trap, allow described far-end receiving trap play the image signal that receives via signal transmission line.
Also some manufacturer can use the transmission of signal conversion regime on the image transmission technology at a distance, but can can't reach the integrality of transmission in its signal transfer process in some cases, especially transmitting at a distance, the situation that its image signal may have phase delay produces, and the far-end receiving trap can't recover the image signal that its clock pulse also can't recover script.
Therefore, it is in front end dispensing device and the transmission of far-end receiving trap on image transmits at a distance with the analog signal differential mode that manufacturer is just arranged, and utilize a differential received module and to postpone the problem that correcting module avoids difference signal phase delay to produce at far-end receiving trap place, and avoid the picture on the screen to have the phenomenon of lack of defination or smear to produce, and its difference signal is to transmit interface via a signal to be sent to described differential received module and to postpone correcting module, and by postponing correcting module generation image sync signal to a display device, so, in the transport process of its difference signal, the supply power that need to continue to its far-end receiving trap to receive its difference signal, but when the front end dispensing device interrupts the transmission of difference signal or does not have the difference signal to transmit, do not install the equipment of automatic office or askiatic powered-down because of its far-end receiving trap, so the supply power that can continue produces the consumption of electric power to the far-end receiving trap, it not only causes expending of the energy, and cause easily its far-end receiving trap because of long-term shutdown cause temperature too high with the problem that influences serviceable life.
The above, have following shortcoming in the prior art:
1. expend the energy;
2. do not cause temperature too high because of shutting down for a long time;
3. influence serviceable life.
Therefore, how to solve above-mentioned existing problem and disappearance, the creator who is this case desires most ardently the direction place that research improves with the relevant manufacturer that is engaged in the industry.
