Background technology:
Telepilot in the market, all be to carry out the transmission of signal by technology such as infrared, it can't possess the audio transmission function, make that the function of telepilot is comparatively single, and directive property is strong, often need aim at receiver, and sensitivity is relatively poor relatively, so on the market not with the telepilot product of wireless microphone, only be the telepilot of simple function, make some audio ﹠ video equipments should be equipped with telepilot, use microphone again, in some demonstration occasions, teaching or meeting occasion need be equipped with laser pen toward contact, make troubles to the user, how to merge these common functions in one, promptly become the object of the utility model research.
Summary of the invention:
The utility model adopts existing ripe 2.4G transport module, designs a kind of telepilot that merges the band ANTENN AUDIO transmission of audio transmission module and laser emitting module.
Technical solutions of the utility model are achieved in that a kind of telepilot with the ANTENN AUDIO transmission, comprise housing, keyboard and built-in control circuit, control circuit comprises keyboard sampling and telecommunication circuit, single-chip microcomputer, transmitter module and power management module, it is characterized in that: control circuit also includes audio frequency access module and laser emitting module, and audio frequency access module and laser emitting module connect single-chip microcomputer respectively; Transmitter module is made up of 2.4GHz wireless transmission circuit and antenna.Increase the audio frequency access module, make telepilot have the function of wireless microphone, and laser emitting module can provide the emission of laser beam, occasions such as convenient teaching are used.
Described audio frequency access module is provided with microphone and inserts interface and pick-up head.Facility wired or that microphone inserts is provided, changes being transmitted to main frame again by telepilot.
Described 2.4GHz wireless transmission circuit comprises that 2.4GHz RF modulation-demodulation circuit, 2.4GHz RF transmit-receive switch circuit, 2.4GHz RF emission amplifying circuit and 2.4GHz RF receive amplifying circuit; 2.4GHz the RF modulation-demodulation circuit connects single-chip microcomputer.
The utility model merges existing multimedia remote controller and wireless microphone and Laser emission in one, voice transmission capabilities with high-fidelity can connect any microphone, realizes the remote-wireless voice transfer, and the light beam of Laser emission, allow the speech or impart knowledge to students more convenient.
Description of drawings:
Below in conjunction with concrete legend the utility model is described further:
The remote controller module block diagram of Fig. 1 band ANTENN AUDIO transmission
Embodiment:
With reference to Fig. 1, the telepilot of band ANTENN AUDIO transmission, comprise housing, keyboard and built-in control circuit, control circuit comprises keyboard sampling and telecommunication circuit, single-chip microcomputer, transmitter module and power management module, wherein also include audio frequency access module and laser emitting module, audio frequency access module and laser emitting module connect on the single-chip microcomputer respectively; Transmitter module is made up of 2.4GHz wireless transmission circuit and antenna.2.4GHz wireless transmission circuit comprises that 2.4GHzRF modulation-demodulation circuit, 2.4GHzRF transmit-receive switch circuit, 2.4GHzRF emission amplifying circuit and 2.4GHzRF receive amplifying circuit; 2.4GHzRF modulation-demodulation circuit connects on the single-chip microcomputer.
Described audio frequency access module is provided with microphone and inserts interface and pick-up head.The access of cable microphone or wireless microphone can be provided, perhaps directly gather sound, facilitate to audition by the pick-up head of telepilot.
Principle of work:
The telepilot keyboard: the instruction of input receiver control is provided, and this keyboard can support to reach up to a hundred function buttons;
Button sampling and telecommunication circuit: gather push button signalling, and adopt I with CPU
2C communication;
Single-chip microcomputer: responsible audio compression and keyboard-coding, and RX transmitting-receiving control is with the switching of RF channel and to sign indicating number;
Power management module: working power is provided, and the intelligent power saving pattern;
Microphone inserts interface: can directly insert the access of cable microphone or wireless words signal, after the mat audio frequency access module high-fidelity speech processes, after the access single-chip microcomputer is handled;
2.4GHzRF the modulation and demodulation circuit, the conversion of signals that single-chip microcomputer is handled becomes the 2.4GHz wireless signal to switch to 2.4GHzRF emission amplifying circuit through 2.4GHzRF antenna duplexer circuit, is gone out by the 2.4GHzRF antenna transmission again.
In this structure, transmitter module adopts dual-mode, and the 2.4GHzRF antenna also can receive the steering order that main frame is sent, and changes remote control mode form etc., and behind Host Shutdown, telepilot in the given time, automatically cutting off power source is to reach power saving effect; Moreover, main frame whenever receives a packet and all feeds back a signal to telepilot, telepilot does not receive feedback signal, can repeat to send the packet of last time, to reach the error correction effect, to guarantee the voice signal transmission continuity, also promptly receive the main frame feedback signal by 2.4GHz RF antenna, receive amplifying circuit, 2.4GHz RF antenna duplexer circuit, the processing of 2.4GHz RF modulation and demodulation circuit feed-in single-chip microcomputer through 2.4GHz RF.
Laser emitting module: by the Keyboard Control firing order, provide emission remote red laser beam, satisfy needing of demonstration and teaching.
