Summary of the invention
In order to overcome above-mentioned weak point of the prior art, the utility model proposes the remote signal switching device, the remote signal that set-top box, DVD telepilot are sent by behind the signal adapting device again modulation and by extended line with the control controlled plant, thereby solved equipment such as set-top box, DVD and TV be placed in diverse location and can be conveniently to their remote control, thereby realized equipment such as DVD, set-top box can be placed on suitable place arbitrarily and do not influenced them and TV is used together and to their remote control.
The utility model is achieved through the following technical solutions: design, a kind of remote signal switching device of manufacturing, comprise interconnecting device and signal emitting head, and described interconnecting device is connected by shielding line with the signal emitting head.
The utility model is further improved to be, described interconnecting device is provided with main control unit and signal receives head, and described main control unit receives head with signal and is connected.
The utility model is further improved to be, also be provided with on the described interconnecting device and logical circuit and shielding line socket, described main control unit, signal receive head, with logical circuit and shielding line socket by being electrically connected.
The utility model is further improved to be, described main control unit transmission carrier signal, described signal receives head and receives remote signal, and described carrier signal and described remote signal form remote-controlled carrier signal and described signal is transferred to described shielding line socket with logical circuit by described.
The utility model is further improved to be that described shielding line end is provided with plug; Described signal emitting head is provided with socket; Described plug inserts described shielding line socket and described signal emitting head respectively.
The utility model is further improved to be, described signal emitting head is the infrared signal emitting head, and described signal receives head and receives head for infrared signal.
The utility model is further improved to be that described main control unit is MCU or 555 timers.
The utility model is further improved to be, described interconnecting device is a TV, and described shielding line socket is located on the shell of described TV.
The beneficial effects of the utility model are: by shielding line and infrared signal emitting head, with the telepilot of signal output apparatus such as DVD, set-top box TV is carried out remote control and just can directly carry out remote control signal output apparatus such as DVD, set-top box, greatly facilitate the remote control of client, can solve simultaneously household electrical appliance such as DVD, set-top box and TV placed apart and do not influence the problem that is used between them again them.

Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
A kind of remote signal switching device comprises interconnecting device and signal emitting head, and described interconnecting device is connected by shielding line with the signal emitting head; Described interconnecting device is provided with main control unit and signal receives head, and described main control unit receives head with signal and is connected; Also be provided with on the described interconnecting device and logical circuit and shielding line socket, described main control unit, signal receive head, with logical circuit and shielding line socket by being electrically connected; Described main control unit transmission carrier signal, described signal receives head and receives remote signal, and described carrier signal and described remote signal form remote-controlled carrier signal and described signal are transferred to described shielding line socket with logical circuit by described; Described shielding line end is provided with plug; Described signal emitting head is provided with socket; Described plug inserts described shielding line socket and described signal emitting head respectively; Described signal emitting head is the infrared signal emitting head, and described signal receives head and receives head for infrared signal; Described main control unit is MCU or 555 timers; Described interconnecting device is a TV, and described shielding line socket is located on the shell of described TV.This interconnecting device can be household electrical appliance commonly used, as TV, refrigerator, air-conditioning etc., in the time of in the practical application, we adopt TV as interconnecting device, as shown in Figure 1, this remote signal switching device is made up of televisor 1, common shielding line extended line 2 and infrared 3.When the client is sitting in the parlor and thinks that remote control is placed in signal output apparatus 4 such as the DVD in other place (as the bedroom) or set-top box, then by picking up the telepilot 16 of corresponding signal output apparatus, carry out remote control facing to televisor 1, remote signal then is transferred on the infrared 3 on the described shielding line extended line 2 by this televisor 1, since this infrared 3 be placed on signal output apparatus 4 such as this DVD or set-top box near, then the remote signal of this infrared 3 can send in DVD or the set-top box, thereby control this DVD or set-top box, thereby realized the signaling transfer point of remote signal.
As shown in Figure 2, be a kind of connection layout of interconnecting device, on existing televisor, increase the control module that remote signal is transferred, as MCU11, it can produce the carrier signal of 38K, increases by one and logical circuit 12 simultaneously.Remote signal is by the infrared receiving terminal 15 of TV, by this and gate 12 TV infrared remote control acceptance 15 set-top box that receive or the non-band carrier signal of DVD infrared remote control are modulated on this 38K carrier wave then, formation can drive the control signal of the band 38K carrier wave of infrared emission head, at last this signal is sent to televisor 3.3MM socket 13 behind, this socket is connected with shielding line, thereby by shielding line control signal is launched.As shown in Figure 3, shielding line extended line 2 inserts in this socket 13, and an other end of this shielding line extended line 2 is equipped with infrared 3, the control signal that transmits from televisor is transferred on this infrared 3 by this shielding line extended line 2, on this infrared 3, control signal is launched then, and the installation site of this infrared 3 should be so that control signal can be received near DVD or set-top box; Because the control signal of this infrared 3 emission can be required the DVD or the set-top box 14 of control and receive, thereby this control signal can be controlled this DVD or set-top box 14, and this DVD or set-top box 14 can receive this infrared remote control signal and make corresponding response according to it.The remote signal that this device can send set-top box, DVD telepilot accept then modulation again by TV and by the extended line transmission of band Infrared Remote-Control Sending head and emissioning controling signal with the control controlled plant.
Using this installs us and promptly signals such as set-top box, DVD can be sent equipment and be positioned over cupboard other rooms even, the user is as long as promptly can be controlled to set-top box or DVD facing to TV remote, and so the TV of chummery can a shared set-top box or DVD yet in the family, thereby satisfies users' household demand.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
