2PROM, even being done outage, the data of being transmitted can not lose safety of data yet, and be convenient to more new data, the external data interface 123 that is connected by second channel 1231 with at least one and described microcontroller 122, be responsible for providing the input channel 1203 of introducing the forwarding data that come from the outside, make the state display interface 124 of wired connection with the third channel 1241 of at least one and described microcontroller 122, do the real-time demonstration of current Channel Transmission state;
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:
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
