Description
Technical field
The utility model relates to a kind of remote controller, relates to a kind of two-way intelligent radio remote-control at audiofrequency device particularly.
Background technology
Existing home appliance remote controller generally adopts the mode of infrared remote control, and infrared remote control is to utilize the carrier wave of infrared light as remote signal, realizes the wireless transmission of remote signal.Infrared light luminescent device and infrared light sensor devices are two kinds of independent devices.The equipment that luminescent device only is housed can only be used for emission, and the equipment that receiving device only is housed can only be used for receiving, and a pair of such transceiver has the restriction that side signal transmission makes progress.Because the restriction of prior art is difficult to the discrimination ratio of different frequency infrared light, infrared remote control all only uses the light wave of fixed frequency as signal carrier, so the antijamming capability of infrared remote control is relatively poor usually.
In addition, there is the shortcoming that purposes is single, directive property is strong in infrared remote control, must aim at infrared remote receiver when using infrared signal that household electrical appliances are carried out remote control, and this has limited the flexibility that remote controller uses; On transportation level, use infrared signal also to limit the quality of signal transmission as channel.Along with the rising of household electrical appliances user specialty degree, infrared remote control can not satisfy user's use needs.Because the infrared signal frequency is very high, the very strong and very easily decay of directive property when transmission, so transmitting terminal must be aimed at receiving terminal and must not have barrier between the two in signals transmission, therefore there is defective in infrared signal aspect channel reliability, can not transmit the signal of big data quantity reliably.
The utility model content
The utility model is for addressing the above problem, utilize 2.4GHz radiofrequency signal directive property strong, can the big characteristics of loaded information amount, a kind of two-way intelligent radio remote-control at audiofrequency device is provided, realize the real-time radio transmission of audio signal and the two-way exchange between home appliance and the remote control, realize more senior man-machine interaction, satisfy user's use needs.
The utility model realizes that the technical scheme that goal of the invention adopts is, a kind of two-way intelligent radio remote-control at audiofrequency device is made up of independent host side and the remote control end that is provided with, the master chip that be used to transmit and receive remote signal of described host side for being connected with the main equipment control unit, described remote control end is by remote-controlled chip, remote keying processing module and remote controller shell are formed, described master chip is provided with radio frequency processing module and the analog/digital converter that is used to transmit and receive radiofrequency signal, and described remote-controlled chip is provided with radio frequency processing module and analog/digital converter corresponding to master chip.
Better, described master chip also connects the audio output of main equipment control unit, described remote-controlled chip also is provided with low pass filter, power amplifier and earphone socket, and remote-controlled chip is connected to low pass filter, power amplifier and earphone socket successively with the audio signal that receives.When the host side transmitting audio signal, the decoding of remote control end generates pulse-width modulation waveform and gives low pass filter and power amplifier amplification and deliver to earphone socket.
Better, described remote control end also is provided with buzzer, and when host side was transmitted two-way intelligent distant control signal and sought remote controller, the remote control end drove buzzer and sounds.Described remote control end is provided with real-time clock module, the clock in host side start back by two-way intelligent distant control function renewal host side.The radiofrequency signal of described radio frequency processing module emission is 2.4GHz.Described main equipment is a television set.
The beneficial effects of the utility model are that the interference free performance and the reliability of remote controller wireless transmission channel improve greatly, do not need extra increasing to send or receiving device when realizing transmitted in both directions simultaneously, have realized that big data quantity, reliable, two-way data transmit.On the other hand, make the user utilize remote controller arbitraryly to listen to the sound of television signal and do not worry bothering other people; The remote controller that can utilize TV to seek to lose and can come to be the TV alignment time with remote controller.
Description of drawings
Fig. 1, embodiment host side structure connection layout.
Fig. 2, embodiment remote control end structure connection layout.
Among the figure, the main control unit of 1 television set, 2 master chips, (3,3 ') analog/digital converter, (4,4 ') radio frequency processing module, 5 remote-controlled chips, 6 real-time clock modules, 7 low pass filters, 8 power amplifiers, 9 earphone sockets, 10 buzzers.
Embodiment
In order to make the purpose of this utility model, technical scheme and technique effect more clear, below in conjunction with accompanying drawing the utility model is described in detail, should be appreciated that described specific embodiment only is used to explain the utility model, and be not used in qualification the utility model.
The two-way intelligent radio remote-control at audiofrequency of a kind of television set device, form by independent host side and the remote control end that is provided with, the master chip that be used to transmit and receive remote signal of described host side for being connected with the main equipment control unit, described remote control end is made up of remote-controlled chip, remote keying processing module and remote controller shell, host side is referring to accompanying drawing 1, the main control unit 1 of television set is connected with the master chip 2 of host side, can carry out the exchange of data and control signal, the master chip 2 of host side is provided with analog/digital converter 3 and radio frequency processing module 4.Remote controller master chip 2 can send and the received RF remote signal by radio frequency processing module 4, and master chip 2 is finished from the work of audio sample, coding and the transmission of television set main control unit 1 by analog/digital converter 3 simultaneously.
The remote control end is referring to accompanying drawing 2, remote-controlled chip 5 be provided with analog/digital converter 3 ', radio frequency processing module 4 ' and real-time clock module 6,, remote-controlled chip 5 connects low pass filter 7, power amplifier 8 and earphone socket 9 successively, and remote-controlled chip 5 also is connected with buzzer 10.Remote-controlled chip 5 is gathered button value and coding, by radio frequency processing module 4 ' send to host side, receives the radiofrequency signal that host side is sent simultaneously then.Seek remote controller if host side is transmitted two-way intelligent distant control signal, then drive buzzer 10 and sound; The generation pulse-width modulation waveform is given low pass filter 7 and power amplifier 8 amplifications and is delivered to earphone socket 9 if host side transmitting audio signal, remote-controlled chip are then decoded.Remote-controlled chip is safeguarded a continual clock by real-time clock functional module 6, the clock in host side start back by two-way intelligent distant control function renewal host side.
