The wireless remote control signals are received through a wireless receiving circuit and converted into electrical signals to be processed, the processed signals are transmitted to a circuit of another area by through cables and restored into the wireless remote control signals to be retransmitted, and other properties of the restored wireless remote control signals remain un-changed except the amplitude. The receiving circuit and a transmitting circuit are mutually and spatially separated, also can be mounted in other equipment respectively, and also can be combined together to use. The device also can be applied to relaying the remote control on remote electric appliance equipment, for example, the remote control on a remote digital television set-top box and the like while watching television can be relayed.
Description
Technical field
The utility model relates to and a kind of wireless signal is carried out the circuit arrangement of relay process, particularly the wireless remote control signal is carried out a kind of circuit arrangement that relaying, fixed point transmit, and belongs to electronic circuit field.
Background technology
At present, comprise that with wireless signals such as infrared ray, radiowave, sound wave, ultrasound waves be the carrier wireless remote control, very general use in daily life, especially infrared remote control is simple in structure with it, and is easy to make, with low cost, the reliability height, anti-interference advantage such as strong is very extensive in the application of the operation control of household electrical appliance such as TV, sound equipment, air-conditioning.But these wireless remote controls are not easy specific area of space is carried out remote-controlled operation.
Especially, just develop to Digital Television in current China from simulated television, after CATV (cable television) turns to numeral from simulation, need be changed by digital TV set-top box, set-top box is matched one to one with televisor, and one family often all has televisor in different rooms, and the televisor in these rooms does not often use simultaneously, demand from signal source, the output of a set-top box can be assigned on a plurality of televisors, but at present, because the limitation of remote control equipment, the operations such as carrying out the program selection that just can not directly use a teleswitch in the place away from set-top box is controlled, and so also just in fact can not share the output of a set-top box.At present, the user of most CATV (cable television) is faced with awkward selection: or need the over-bought digital TV set-top box, overpay license fee, and bring waste and increase financial burden; The TV signal of having to abandon in some room inserts, and has influenced actual watching.
That is to say, cause the reason of this difficult problem, is exactly that present wireless remote control is difficult for carrying out remote fixed-point operation technically.
Summary of the invention
Be difficult for long-distance remote control is carried out in specific zone in order to overcome wireless remote-control system commonly used at present, especially be that the telechirics of domestic electric appliances such as digital TV set-top box is difficult for the shortcoming of operating at a distance in other rooms, the utility model provides a kind of relay of wireless remote control signal, to address this problem.
In order to achieve the above object, the utility model is to address this problem the technical scheme that is adopted to be: at place, remote control source and remotely-controlled equipment place, receiving conversion circuit and reduction radiating circuit are set respectively, the connection by cable comes transmission of electric signals each other.The receiving conversion circuit receives the wireless remote control signal and exports electric signal; Reduction radiating circuit input electrical signal also restores the wireless remote control signal.The receiving conversion circuit can be made up of wireless signal receiver spare, conversion process circuit, circuit delivery outlet; The reduction radiating circuit can be made up of circuit input port, reduction treatment circuit, wireless signal transmitter spare.The circuit of receiving conversion circuit and two parts of reduction radiating circuit is separated from each other on the locus, can be placed in the case of machine separately respectively or be placed in televisor, in other equipment such as set-top box, and the use that also can a plurality ofly link together each other, during work, wireless signal receiver spare in the receiving conversion circuit is behind the wireless remote control signal that receives, be transformed into electric signal, deliver to the conversion process that the conversion process circuit carries out the frequency spectrum and the level of electric signal, export from the circuit delivery outlet, signal wire by cable connects again, be sent to the circuit input port in the reduction radiating circuit, deliver to the conversion process once more that the reduction treatment circuit carries out the frequency spectrum and the level of electric signal then, at last by wireless signal transmitter spare, launch the wireless remote control signal that has reduced.Its essential principle is to utilize electronic circuit, earlier receiving with the wireless remote control signal, deliver to another required zone with cable behind the electric signal that is transformed into, again with circuit arrangement, be reduced to size except that its amplitude can change, the not reformed wireless remote control signal of other characteristic is launched again.
For example, in the dwelling house of one family, wherein there is a room that digital TV set-top box is housed, in other a plurality of rooms televisor is housed all, all load onto the receiving device of wireless remote control signal so near each televisor, load onto the ballistic device that can restore the wireless remote control signal near digital TV set-top box, the centre is connected with signal cable, like this with the telepilot of set-top box, can the remote set-top box of remote control before all have installed the televisor of receiving device additional.The ballistic device of the receiving device of wireless remote control signal, wireless remote control signal can have independently cabinet, also can be directly installed in televisor or the set-top box.
Voice-frequency cable, vision cable or radio-frequency cable be connected owing to have between set-top box and each televisor, can be transmitting from being superimposed upon voice-frequency cable, vision cable or radio-frequency cable after the electric signal that receiving device is sent to ballistic device is modulated.
Because receiving device and ballistic device all need electricity consumption, also can be carrying out DC feedback from the electric signal that receiver is sent to transmitter, also promptly in receiving device or ballistic device, direct current tie line is set, making has direct current biasing on the signal cable, receiving device and ballistic device just can shared direct supplys like this.
Because the digital TV set-top box of some does not have radio frequency output at present, can be installed in rf modulation circuit to the ballistic device of remote signal.
Because present each family all has a plurality of rooms to need televisor basically, in signal source of chummery long-distance remote control not will be commonplace, thereby receiving device and ballistic device just can directly be placed on other domestic electric appliances such as televisor and set-top box respectively, and using so just can be convenient.
The beneficial effects of the utility model are, because after a series of conversion of wireless remote control signal via receiving device in the utility model and transmitter, except that the signal amplitude size can change, other characteristic is not changed, so the wireless remote control device for different size or different manufacturers can be conveniently general, and need not pay close attention to its characteristics such as specific coding.
The utility model not only can be used in the relaying in the CATV (cable television) remote control, also can be used in the relaying in the audio frequency and video output device remote controls such as DVD, the same relaying that also can be used in the domestic electric appliance remote controls such as air-conditioning, electric controlled door.
