Abstract
The invention discloses an RF remote-controller with an earphone, which comprises a keyboard, an MCU (Microprogrammed Control Unit) processor, an RF transceiver, a D/A (Digital-to-Analogue) conversion module, an audio amplification circuit and an earphone interface. Signals input by a signal source are processed by the MCU processor, and the processed signals are output through the serial port of the MCU processor to drive the RF transceiver to transmit remote control signals; audio data remote control signals sent by electrical equipment are input to the MCU processor through the serial port of the MCU processor to be processed after being received by the RF transceiver, and the processed audio signals are converted by the D/A conversion module; and the converted audio signals are output by the earphone interface after being amplified by the audio amplification circuit. Based on a bluetooth technology, the invention realizes the two-way information transmission of digital audio signals and the high fidelity of the signals; users listen music through the earphone, and therefore, any influence is not generated on other people; due to the non-directional property of RF, listening the music by a controller at home is freer.
Description
Technical field
The invention belongs to the wireless remote control technology field, especially relate to a kind of RF with earphone (radio frequency) telepilot and control method thereof with bidirectional transfer of information.
Background technology
It is infrared IR (Infrared) telecontrol engineering that traditional household electrical appliance remote controller substantially all adopts, the IR remote control need to be operated just good response can be arranged facing to receive window, if remote control reception part has been fallen outside 30 degree emission angle scopes of telepilot or there are object resistance shelves centre, remote control will be malfunctioning; The light of high brightness also can disturb infrared emission head, and especially infrared remote control can't be realized two-way transmission.To listen to sound accompaniment in order realizing on the IR telepilot, normally at the IR telepilot, to add the audio signal receiving circuit, but such improvement can not realize freely listening to the function of high-fidelity sound accompaniment, fails to obtain comparatively general application.Thus, traditional IR telepilot can not meet growing demand.
Summary of the invention
The object of the present invention is to provide a kind of RF with earphone (radiofrequency) telepilot that can realize bidirectional transfer of information, solve the defect that prior art exists.
For achieving the above object, the present invention adopts following technical scheme:
A kind of telepilot of the RF with earphone, comprise keyboard, MCU processor, RF transceiver, and the signal of signal source input is processed by the MCU processor, and the signal after processing drives RF transceiver emission remote signal by the serial ports output of MCU processor; Also comprise D/A modular converter, audio amplifier circuit and earphone interface, serial ports by the MUC processor after the voice data remote signal that electrical equipment that described RF transceiver receives sends is input to the MCU processor and is processed, and the sound signal after processing is changed by the D/A modular converter; Sound signal after conversion is exported by earphone interface after amplifying by audio amplifier circuit.
Preferred scheme is: described MCU processor comprises keyboard scan and information storage module, control module and communication module; Described keyboard scan and information storage module are connected with control module, and control module is connected with communication module.
Another object of the present invention is to provide a kind of control method of the telepilot of the RF with earphone.
For achieving the above object, the present invention adopts following technical scheme:
Described MCU processor is processed emission voice step: (a) initialization serial ports judge whether voice suggestion opens, as open execution step (b); As close, return to step (a); (b) detect keyboard whether the data input is arranged; Enter step (c); (c) detect voice data, after having detected, enter step (d); (d), if voice data is arranged, outputting audio data, if the absence of audio data are returned to step (a); Described MCU processor is processed and is received the voice step and be: (a) initialization serial ports judge whether the radio reception prompting opens, as open execution step (c); (c) detect voice data, after having detected, enter step (d); (d), if voice data is arranged, outputting audio data, if the absence of audio data are returned to step (a).
The present invention compared with prior art, has following advantage and beneficial effect:
Telepilot of the present invention is based on Bluetooth technology, at the electrical equipment with DAB output (as Set Top Box, digital TV integrated machine etc.) the reciprocity RF transceiver of upper installation, electrical equipment sends voice data to telepilot, simultaneously, if electrical equipment receives the operational order of telepilot, also can convert operational order to speech data and send to telepilot and the operating result speech data is also sent to telepilot; Telepilot receives data by the D/A conversion operations, and audio frequency amplifies, and then sound accompaniment, operational order voice, operating result voice output is arrived to earphone, realizes bidirectional transfer of information.People's operation that operation sound prompt function of the present invention can conveniently have defective vision; What the present invention was transmitted is digital audio and video signals, has accomplished the high-fidelity of signal, guarantees audibility; By earphone, supply the user to listen to, on around other people do not produce any impact; Non-directional due to RF, listen to music by telepilot at home freer.
