Coding corresponding to number, the control so as to issue different control signals by different phonetic orders, to different electric appliances
Or the control to identical electric appliance different function.Signal conversion module 15 receives and parses through modulation wireless signal to generate control letter
Number, and control signal is sent to electrical equipment to control the electrical equipment.If the mesh obtained from feature extraction unit 142
The ratio of default phonetic feature comparison in mark phonetic feature and memory module 16 is less than the language set in threshold setting unit 141
When sound characteristic matching threshold value, the matching analysis unit 143 issues infrared conversion negative-feedback signal to mesh networking module 19, or not to
Mesh networking module 19, which issues feedback signal namely signal conversion module 15, will not issue control signal.
For example, it is assumed that the default phonetic feature in memory module 16 is the phase of the directive statement " please open fan " of user A
Phonetic feature is closed, if the first acquisition module 11 collects " opening fan " in user A or user B, " please open fan " or " opens
The associated speech data of the directive statements such as fan ", voice data of the preprocessing module 13 to the directive statement of user A or user B
Removal of impurities pretreatment is carried out, obtains the target speech data of directive statement, the feature extraction unit 142 of speech recognition module 14 is to mesh
It marks phrase data and carries out speech feature extraction, the matching analysis unit 143 is by the A obtained from feature extraction unit 142 or user B
The related objective phonetic feature and memory module 16 of directive statements such as " open fan ", " fan please be open " or " opening fan " in
User A directive statement " fan please be open " preset phonetic feature comparison, if its comparison ratio set more than or equal to threshold value
When setting the phonetic feature matching threshold set in unit 141, if the threshold value is to obtain in 90% namely feature extraction unit 142
A or user B the related objective phonetic feature of directive statements such as " open fan ", " fan please be open " or " opening fan " with deposit
When storing up the ratio of the default phonetic feature of directive statement " fan please be open " of the user A in module 16 more than or equal to 90%, recognize
To be successful match, then the matching analysis unit 143 generates positive feedback signal and is transferred to signal tune by mesh networking module 19
Molding block 12, signal modulation module 12 are modulated the positive feedback signal and generate modulation wireless signal, signal conversion module
15 receive and parse through the modulation wireless signal, generate corresponding control signal, and control fan by the control signal and open.Instead
The matching analysis unit 143 generate to signal conversion module 15 and issue signal conversion negative-feedback signal, or not to signal modulus of conversion
Block 15 issues signal conversion feedback signal namely signal conversion module 15 is failure to actuate.
Fig. 5 A-5B is please referred to, mesh networking module 19 includes root node routing 191 and child node route device 193, root node
