Add network: the voice control command of sending networking; Through pickup unit (5); Amplifying circuit (6); Pronounciation processing chip (7); Memory cell (3) is carried out speech recognition; Judge the similarity of corresponding order in this voice control command and the voice command entry storehouse (73); If similarity is higher than its decision threshold; Judge that then this voice command is effective and from command code storehouse (74), search corresponding networking command code; Send this command code to main control chip (9); Use control protocol (91); This command code is resolved to executable networking login control command first; With addresses distributed in the networked remote control device net; Authentication code; Bar code; Send to the main control device in the net after the information that identification code etc. possess authentication function uses key to encrypt, add network after accomplishing authentication; Successfully perhaps failure networks; Main control chip (9) sends corresponding information to pronounciation processing chip (7); Pronounciation processing chip (7) is according to this information and utilize the synthetic corresponding information of voice prompt in phonetic synthesis unit (71); After power amplifier unit (8) amplifies, send relevant voice information, realize with user's voice mutual by sounding parts (4);
Broadcasting control: after the networking success; The user sends broadcasting control voice command with voice; Through pickup unit (5); Amplifying circuit (6); Pronounciation processing chip (7); Memory cell (3) is carried out speech recognition; Judge the similarity of corresponding order in this voice control command and the voice command entry storehouse (73); If similarity is higher than its decision threshold; Judge that then this voice command is effective and from command code storehouse (74), search corresponding broadcasting control control command sign indicating number; Send this command code to main control chip (9); Use control protocol (91); This command code is resolved to executable broadcasting control command, other household electrical appliances issues in net;
Target household electrical appliances single-point control: after the networking success; The user is through single-point control voice command; Carry out speech recognition through pickup unit (5), amplifying circuit (6), pronounciation processing chip (7), storage unit (3); Judge the similarity of corresponding order in this voice control command and the voice command entry storehouse (73),, judge then that this voice command is effective and from command code storehouse (74), search the single-point control command sign indicating number and the target household electrical appliances address of correspondence if similarity is higher than its decision threshold; Send this command code and target household electrical appliances address to main control chip (9); Use control protocol (91), this command code is resolved to executable broadcasting control command, to the target household electrical appliances issue of assigned address;
Library file remote interaction: after the networking success; The acoustic control telepilot carries out transparent transmission through household electrical appliances in the net of band gateway function to be realized getting in touch with the foundation of long-range subscriber terminal equipment; Voice remote controller gets into the interactive voice state; Under this state; Voice messaging will directly be identified as corresponding character entry in the voice command entry storehouse (73) through pickup unit (5), amplifying circuit (6), pronounciation processing chip (7), storage unit (3), sends main control chip (9) to and does not do later conversion, sends household electrical appliances in the net of being with gateway to through Intranet; And then send long-range user terminal to; The information of user terminal is through the tame main control chip (9) that electrically communicate to voice remote controller in the net of band gateway, and main control chip (9) directly is transmitted to pronounciation processing chip (7) with this information, searches the middle relevant voice element in voice messaging storehouse (32) through phonetic synthesis unit (71) and carries out phonetic synthesis; And through sounding parts (4) information of remote user terminals is expressed with the form of voice, realize voice status down with the long-distance user alternately;
Remote library document upgrading: after the networking success; The user is through the remote upgrade voice command; Carry out speech recognition through pickup unit (5), amplifying circuit (6), pronounciation processing chip (7), storage unit (3); Judge the similarity of corresponding order in this voice control command and the voice command entry storehouse (73); If similarity is higher than its decision threshold, then judge this voice command effectively and from command code storehouse (74), search the identification code of corresponding remote update command sign indicating number and upgrading object library, send the identification code of this command code and upgrading object library to main control chip (9); Main control chip (9) uses control protocol (91) this command code to be resolved to the identification code of executable remote update command and upgrading object library; Carry out transparent transmission through household electrical appliances in the net of band gateway function, be connected on the remote terminal that includes voice remote controller upgrading library file, and download the corresponding upgrading object library file to main control chip (9) from this remote terminal; Then corresponding library file is upgraded covering, send renewal by pronounciation processing chip (7) after renewal is accomplished and accomplish information of voice prompt.
