Signal emission module is arranged in the position of other electrical equipment of remote-controlled many electrical equipment, receives the remote signal after the described modulation and sends to other electrical equipment.
In many electrical equipment of being controlled by described remote control circuit, different electrical equipment adopts different remote control coding modes and different customer numbers, though so be by the remote signal after the same bars transmission line modulation, can be not interfering with each other between the different electrical equipment yet.
Preferably, described first electrical equipment is televisor, and other electrical equipment in described many electrical equipment is one or more in DVD player, set-top box and the other televisor.
Preferably, the position of other electrical equipment in described remote-controlled many electrical equipment is the dead ahead of the receiver of remote-control sytem of described other electrical equipment.
Preferably, described modulation module loads carrier wave to remote signal.
Preferably, described signal emission module is an infrared-emitting diode.
The utility model also provides a kind of televisor, comprising:
The remote control induction module receives the remote signal that telepilot is launched;
Modulation module is connected with described remote control induction module, is used to modulate the remote signal that the remote control induction module receives;
Signal transmssion line connects described modulation module and signal emission module, and the remote signal after the modulation is transferred to signal emission module from modulation module;
Signal emission module is positioned at the position of remote-controlled other electrical equipment, receives the remote signal after the described modulation and sends to other electrical equipment.
Preferably, televisor also comprises master chip, receives remote signal from described remote control induction module.
The utility model has increased the remote control circuit after improving in televisor, the remote signal of telepilot being sent with a bars transmission line is transferred near in check other electrical equipment, gives corresponding electrical equipment with form wireless transmit such as infrared again.Pass through signal transmssion line, prolonged the transmission range of remote signal, eliminated the influence that barrier causes remote signal, therefore can be placed on unconspicuous position, room to various in check other electrical equipment, even can be placed in cabinet the inside or other the room, and the user is as long as the receiver of remote-control sytem of the telepilot of corresponding electric appliance being aimed at TV during remote control can be realized remote control exactly.
Description of drawings
Fig. 1 is the synoptic diagram of the remote control circuit preferred embodiment that provides of the utility model;
Fig. 2 is the circuit theory diagrams of the remote control circuit preferred embodiment that provides of the utility model.
Embodiment
In order to make those skilled in the art person understand the utility model scheme better, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with embodiment and embodiment accompanying drawing.
As depicted in figs. 1 and 2, the remote control circuit of many electrical equipment of control of the present utility model is used to control televisor 10 and other electrical equipment 20 of Duo Tai as first electrical equipment.
The remote control induction module 102 of televisor 10 is used to receive the remote signal to electrical equipment that telepilot 101 sends, this telepilot 101 can be with televisor 10 and other electrical equipment 20 in the middle of any telepilot that matches.Usually, telepilot 101 sends infrared remote-controlled signal, and 102 of remote control induction modules are infrared inductors.
The remote signal that remote control induction module 102 receives is transfused to the master chip 103 of televisor 10.Simultaneously, this remote signal also is transfused to the remote control circuit of being made up of modulation module 1041, signal transmssion line 1042 and signal emission module 1,043 104.
Modulation module 1041 will be modulated again from the remote signal that remote control induction module 102 receives, and the process of modulation is that this remote signal is loaded the 38k carrier wave; Signal transmssion line 1042 is transferred to signal emission module 1043 to the remote signal through ovennodulation, and signal transmssion line 1042 can adopt RS232 bus-type data line; Because what adopt is the mode of wire transmission, signal transmssion line 1042 can be transported to each position in room, place to the remote signal after the modulation from televisor 10, comprises furniture cabinet inside, or is transported to other room beyond the room, televisor 10 place; As seen, this signal transmssion line 1042 has prolonged the effective range of the remote signal that telepilot 101 sends, and makes it no longer be subjected to the restriction of distance and barrier aspect.
Signal emission module 1043 can adopt infrared-emitting diode, and other electrical equipment 20 of butt joint remote controlled sends infrared remote-controlled signal; This signal emission module 1043 should be set at the position that can carry out remote control to other electrical equipment 20, promptly require this module distance want other electrical equipment 20 of remote control nearer and also between clear, preferably make it to be positioned at the dead ahead of the infrared remote control receiver of other electrical equipment 20.
Remote control circuit 104 shown in Fig. 1 only comprises a signal emission module 1043, by this module a plurality of other electrical equipment 20 is imposed remote control.But those skilled in the art should be able to recognize, look a plurality of other electrical equipment 20 relative position situation each other, a plurality of described signal emission module 1043 also can be set, for example, can place a described signal emission module in the dead ahead of every other electrical equipment.
Other electrical equipment 20 can comprise DVD player, set-top box, one or more in the middle of the perhaps other televisor.Different electrical equipment adopts different remote control coding modes to carry out remote control with different customer numbers, the control chip of each electrical equipment inside compares the remote signal that receives, have only when the customer number of remote signal is consistent with this machine, just to respond remote signal and, otherwise just abandon remote signal according to the command-execution operation of remote signal.Though so be by the remote signal of same bars transmission line 1042 after to each electrical equipment transmission modulation, can be not interfering with each other between the different electrical equipment yet.
The above only is an embodiment of the present utility model, and the utility model can also be applied in other opertaing device, as multiple point touching system for TV set, computer system, man-machine games system, optical projection system, cell phone system etc.Protection domain of the present utility model is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
