The present invention has following conspicuous advantage compared with prior art:
1. realized the bumpless transfer of radio frequency, expanded the limited applications distances of infrared control to infrared output signal.
2. only by a controller,, can control a plurality of home appliances simultaneously with regard to alternative a plurality of different types of Infrared remote controller.
3. need not connect up, rewiring or the application scenario that is difficult to connect up especially suit to have fitted up and do not thought.
4. the current environment of wireless channel how, can show in real time, is convenient to install and monitoring.
Description of drawings
Accompanying drawing 1 is a functional-block diagram of the present invention.
Accompanying drawing 2 is the functional-block diagram of the preferred embodiment of the present invention.
Embodiment
Details are as follows in conjunction with the accompanying drawings for a preferred embodiment of the present invention:
See also Fig. 1, Fig. 1 is a frame principle figure of the present invention, and the present invention is by the RF transceiver 11 that is linked in sequence, data forwarding controller 12, and infrared modulator 13 is formed.Wherein RF transceiver 11 is introduced extraneous electromagnetic wave signal with the modulation of carrier wave form by antenna through antenna feeder (1101), in the present embodiment, employing need not license the frequency resource of the open frequency range of ISM, make the wireless receiving of radio-frequency carrier and, carry out the demodulation of modulated wave with digital demodulation mode such as FSK mode.Can certainly adopt known any less radio-frequency transmission (both can be one-way transmission, also can be transmitted in both directions) technical scheme, as adopt bluetooth Bluetooth, WLAN (wireless local area network) Wlan, home network HomeRF, super wideband UWB (Ultrawideband) makes the radio frequency platform of wireless receiving.
By RF transceiver 11 demodulated data signals, through wired first input end 1201 that is sent to data forwarding controller 12, do identification and decoding, and produce desired forwarding data, by wired input 1202 that is sent to infrared modulator 13,
Make the Digital Modulation of infrared mode, and send forwarding data through infrared modulated through output channel 1301 and infrared emission media (as omnirange type infrared emission rod), at this, the wireless transmission pattern of the infrared technique modulation of being adopted is the carrier transmit pattern of any infrared technique modulation and transmission information;
From second input 1203 of data forwarding controller 12, be to introduce extraneous data code flow sequence with the data form, effect is to solve the local forwarding data that need through infrared modulated of importing, and the local approach that data are upgraded at any time and upgraded of transmitting is provided.
See also Fig. 2, Fig. 2 is the frame principle figure of the embodiment of data forwarding controller 12 of the present invention, mainly comprises:
MCU microcontroller 122, its function is, demodulating data by first input end 1201 is introduced, carry out data identification and decoding, differentiate the control types and the control purpose of data, produce the forwarding digital coding of the output that requires then, be sent to the input of infrared modulator 13 by serial output interface 1202.
E 2PROM121 does the data storage by receiving from the data line interface 1211 of MCU microcontroller 122, and in the present embodiment, that data line interface 1211 adopts is I 2The C data/address bus is by 122 couples of E of MCU microcontroller 2PROM121 carries out the operation that reads or writes of data; Function is to prevent to cut off the power supply back forfeiture legacy data, guarantees data security storage and renewal at any time.
External data interface 123 is by external data line 1203, introduce the forwarding data that need local update and storage, and have the effect of adjusting external data physical format (level value, transmission rate etc.) and MCU microcontroller 122 compatibilities, and be connected with MCU microcontroller 122 by internal data line 1231.
State display interface 124 is connected with MCU microcontroller 122 by lead-in wire 1241, it is after MCU microcontroller 122 detects the wireless channel reception environment in real time, the ambient condition display interface of output, in the present embodiment, it also can be a dichromatic LED, when unimpeded, then send long bright green light to wireless channel; If wireless channel during near threshold value, sends the flicker green light; If when wireless channel can't be worked, then send long azarin coloured light, as for the source of this status signal, fully can be in the emitter (not shown), a kind of function is set, that is: in the time slot that useful signal produces, periodically produces the detection data that is used for the monitoring wireless channel status.
Because the remote control code of home appliance is varied, MCU microcontroller 122 will deposit E in advance from the external data (promptly representing different remote control code data) of passage 1231 2Among the PROM121, the usefulness of the control data when doing to transmit; And, then can regard the address information that needs to transmit data as from the demodulating data of passage 1201, can find corresponding remote control code data by corresponding address information.
