Description
Technical field
The utility model relates to infrared retransmission unit, particularly television set infrared remote control signal transfer apparatus.
Background technology
Along with the slimming of television set develops, in order to conserve space and attractive in appearance, increasing user wishes television external device (being hereafter the referred to as Set Top Box) hiddens such as Set Top Box, DVD, player to install, but Set Top Box etc. are outer is provided with the remote control system of controlling oneself, the receiver of remote-control sytem of Set Top Box must be leaked outside and could normally use.At present, part Set Top Box has reserved remote control reception input port on the market, by connecting line, receiver of remote-control sytem is external in daylight, or uses special infrared remote control transponder, thus the hidden realizing Set Top Box is installed.Although these methods meet the user's request that Set Top Box hidden is installed, its receiver of remote-control sytem leaked outside or transponder, and its connecting line also in the open, still affects overall aesthetics.Therefore, for users, the hidden realizing Set Top Box in the urgent need to a kind of televison set remote-control signal retransmitting device is installed and uses.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of television set infrared remote control signal transfer apparatus, solves the problem cannot carrying out control very well to hidden Set Top Box.
For solving the problem, the technical solution adopted in the utility model is: television set infrared remote control signal transfer apparatus, comprising: the signal isolation circuit be connected with TV remote receiver module, remote control output interface socket for being connected with set box remote control input interface socket; Described buffer circuit is connected with described remote control output interface socket.
Further, MCU modulation circuit, drive circuit, infrared transmitter is also comprised; Described buffer circuit is connected with MCU modulation circuit, and MCU modulation circuit is connected with drive circuit, and drive circuit is connected with infrared transmitter by described remote control output interface socket.
Further, between drive circuit and infrared transmitter, amplifying circuit is connected to
The beneficial effects of the utility model are: realize the isolation of signal by buffer circuit and copy, and the signal copied is delivered to set box remote control input interface socket by remote control output interface socket, achieve the forwarding of remote signal, make hidden Set Top Box also can receive remote signal, meet the demand that people control hidden Set Top Box.
Accompanying drawing explanation
Fig. 1 is example structure schematic diagram;
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in fig. 1, the television set infrared remote control signal transfer apparatus of embodiment comprises: the signal isolation circuit be connected with TV remote receiver module, remote control output interface socket for being connected with set box remote control input interface socket; Described buffer circuit is connected with described remote control output interface socket.The signal that wherein signal isolation circuit is used between remote control retransmission unit and TV main circuit is isolated and copies, and for remote-control signal retransmitting device provides remote control input signal, does not affect TV main circuit simultaneously and receives remote signal; Remote control output interface socket, for remote control output signal plug wire, is connected to set box remote control signal input interface by connecting line.The present embodiment utilizes the remote control reception module of television set, and the remote signal that remote control reception module receives is passed to signal isolation circuit, and signal is isolated, copied by buffer circuit, is outputted to set box remote control and receives input port.
Further, for the Set Top Box not possessing remote control reception input port, MCU modulation circuit, drive circuit, infrared transmitter, amplifying circuit can be increased in television set infrared remote control signal transfer apparatus, and buffer circuit is connected with MCU modulation circuit, MCU modulation circuit is connected with drive circuit, drive circuit is connected with infrared transmitter by described remote control output interface socket, and amplifying circuit is connected between drive circuit and infrared transmitter.MCU modulation circuit is used for the remote control modulation signal remote signal received be converted to containing 38KHz carrier wave; Drive circuit is used for providing driving force to the remote control modulation signal of above-mentioned 38KHz carrier wave, drives external infrared transmitter work; Remote control output interface socket, for remote control output signal plug wire, is connected to set box remote control signal input interface by connecting line.The signal copied by buffer circuit by MCU modulation circuit exports the carrier signal for 38KHz, and through amplifying circuit, launched by infrared transmitter, Set Top Box is received this signal by its built-in remote control reception module and processed.
The course of work of the present embodiment is as follows: first remote control transmitter launches the infrared signal of 38KHz to TV remote receiver module, then the infrared signal of 38KHz is passed to buffer circuit by TV remote receiver module, buffer circuit is by this signal replication, and the signal copied is delivered to set box remote control input interface socket by remote control output interface socket, last main box identification remote control mode also performs.
For the Set Top Box not possessing remote control reception input port, buffer circuit by the signal transmission that copies to MCU modulation circuit, the reproducing signals received is exported the carrier signal for 38KHz by MCU modulation circuit, then amplifying circuit is passed to, infrared transmitter is passed to again after amplifying circuit amplifies, the carrier signal of the 38KHz received is launched by infrared transmitter, then received by the remote control reception module of Set Top Box, the remote control reception module of Set Top Box by the signal transmission that receives to main box, finally performed by main box identification remote control mode.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
