Abstract
The utility model relates to a wireless infrared repeater. The repeater consists of an infrared signal, an amplifying circuit, a wireless analog signal, a wireless transmission signal and a power supply module, wherein the receiving end of the infrared signal receives a digital signal and transmits the digital signal to the amplifying circuit; the amplifying circuit converts the received digital signal into the wireless analog signal; and the output end of the wireless analog signal is connected with the wireless transmission signal and powered by a power supply module. The wireless infrared repeater provided by the utility model converts the digital signal into the wireless analog signal, achieves signal transmission and forwarding between a room and a living room without communication lines, and has the advantages of small size, low power consumption, powerful functions, high stability and low cost.
Description
Technical field
The utility model relates to infrared repeater system field, especially a kind of Radio infrared transponder that is applicable to Modern Family's DTV STB, telecommunications iTV STB, satellite set top box, high definition player, VCD, DVD, stereo set.
Background technology
Along with expanding economy, the amenities of life of people's pursuing high quality, DTV have got into family; And TV set-top box also gets into family thereupon, for the user who has multiple TV set in the family, a TV set-top box only is installed; Just can only watch in the parlor, the TV in other room can't be watched; STB dismounting between parlor or room, changing of shifting from one place to another seen, moves loaded down with trivial details, very inconvenient; The multiple TV set top box is installed, and the monthly rent license fee usefulness of expensive STB purchase commodity and long-term expenditure has increased family's expenditure.
The infrared transponder that occurs does not in the market possess wireless transmission function, and it uses cumbersome.
The utility model content
The technical matters that the utility model will solve is: in order to overcome the above-mentioned middle problem that exists, provide a kind of and be easy to use and the Radio infrared transponder that does not receive the restriction of space length and barrier.
The utility model solves the technical scheme that its technical matters adopted: a kind of Radio infrared transponder; Being used for supporting top box of digital machine uses; Form by infrared signal, amplifying circuit, wireless simulation signal, wireless signal transmission and supply module; Described infrared signal is transferred to amplifying circuit by the receiving end receiving digital signals; Amplifying circuit converts the wireless simulation signal to through the digital signal that receives, and connects wireless signal transmission on the wireless simulation signal output part and passes through the supply module power supply.
Also be connected with mu balanced circuit on the described infrared signal output terminal, be connected with pilot lamp on the circuit output end of pressure-stabilizing.
The beneficial effect of the utility model is: the Radio infrared transponder of the utility model; Convert digital signal to the wireless simulation signal; The existence that can between room and parlor, not need communication line just can realize that the transmission of signal transmits, and this transponder has that volume is little, low in energy consumption, function is strong, stable height and cost are low.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structured flowchart of the utility model.
1. infrared signals among the figure, 2. amplifying circuit, 3. wireless simulation signal, 4. wireless signal transmission, 5. supply module, 6. mu balanced circuit, 7. pilot lamp.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the synoptic diagram of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Radio infrared transponder as shown in Figure 1; Being used for supporting top box of digital machine uses; Form by infrared signal 1, amplifying circuit 2, wireless simulation signal 3, wireless signal transmission 4 and supply module 5; Be transferred to amplifying circuit 2 and mu balanced circuit 6 by the receiving end receiving digital signals through infrared signal 1; Be connected with pilot lamp 7 on mu balanced circuit 6 output terminals, amplifying circuit 2 converts wireless simulation signal 3 to through the digital signal that receives, and connects wireless signal transmission 4 on wireless simulation signal 3 output terminals and passes through supply module 5 power supplies.
The principle of work of the Radio infrared transponder of the utility model: receive infrared signal 1 by receiving end; Infrared signal 1 after the reception converts digital signal to wireless simulation signal 3 through amplifying circuit 2; Convert wireless simulation signal 3 to wireless signal transmission 4 transmission, at last through the telepilot feedback.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the instructions, must confirm its technical scope according to the claim scope.
