Be further described below by the method for different application scenarioss to the embodiment of the present invention.
Fig. 5 enters the home intranet method flow diagram of turning on light in room, comprises the following steps:
Step 501: if user enters certain room, say " illumination " facing to illuminating lamp, the transducer near illuminating lamp gathers user speech;
Step 502: transducer sends to terminal by power line after described user speech is converted to digital signal;
Concrete, first transform acoustical signals is become the signal of telecommunication by transducer, and the signal of telecommunication is transformed into digital signal again, digital signal again through ovennodulation, amplification, coupling, then by power line transmission to terminal.
Step 503: terminal demodulates original digital signal from power line, and the device address parsing control command " illumination " and illuminating lamp, return to described transducer by described control command " illumination " by power line;
Here, the control command of the original digital signal demodulated and storage and corresponding household electrical appliance title are mated by terminal, parse the device address of control command " illumination " and illuminating lamp.
Step 504: in transducer, grammed switch receives control command " illumination " opening power afterwards, and electric light brightens;
Step 505: need say " closedown " facing to illuminating lamp when user will withdraw from a room, user speech is transferred to terminal equally, is turned off the light by terminal control.Other electrical equipment operation mode roughly the same, does not repeat them here.
Special instruction, multiple device identifying information is store in terminal, these identifying informations are all the control command and corresponding household electrical appliance title that are converted to by voice signal " illumination ", " TV ", " computer ", " air-conditioning ", " washing machine ", " closedown ", that is when user cries out control command and/or device name on household electrical appliance side, user speech is just transferred to terminal, terminal to the comparison receiving digital signal and storage, thus determines control command and destination home appliance.By this kind of voice-controlled manner, terminal can control the different household electrical appliance in different room, and user can arbitrarily open and close the household electrical appliance such as TV, electric light, air-conditioning.
Fig. 6 to connect flow chart first according to the data service of the embodiment of the present invention, comprises following step:
Step 601: terminal, before the data connection request not receiving household electrical appliance, generally automatically can not connect, compare resource-saving like this, therefore data cube computation is all first initiate data connection request message by household electrical appliance;
Step 602: the transducer be connected with household electrical appliance by data connection request message through power line transmission to terminal;
Step 603: terminal receives data connection request message, knows the address information of household electrical appliance, connect according to described address information according to described data connection request message.
Fig. 7 is the data traffic transmission flow chart according to the embodiment of the present invention, comprises following step:
Step 701: terminal inserts supply socket by charger, each transducer inserts the supply socket on each household electrical appliance side, and the network interface of transducer is connected to household electrical appliance by netting twine;
Step 702: user says " file transfer " on a certain household electrical appliance side, the transducer on described household electrical appliance side gathers user speech and converts the digital signal of applicable power line transmission to, enters terminal by power line transmission;
Step 703: terminal is after filtering, demodulation restores raw digital signal, and after parsing control command " file transfer ", open continuous data business transfer function.
Fig. 8 to connect flow chart first according to the speech business of the embodiment of the present invention, comprises following step:
Step 801: speech business first connection is initiated by terminal, when terminal speech reminding business is triggered, will need the digital signal of the prompt tone play to enter all transducers through power line transmission immediately;
Step 802: each transducer demodulation process, recovers prompt tone;
Step 803: after a certain household electrical appliance nearby users hears sound, user knows phone, will send the voice of " answering " immediately, and described user speech is converted to digital signal through power line transmission to terminal;
Step 804: terminal parses control command and " answers " and the address of household electrical appliance at user place from described digital signal, performs control command and " answers ", and connect with the transducer corresponding to described household electrical appliance.
Here, terminal is in listening state always, has information transmission to come, will connect immediately as long as listen to transducer corresponding to any one household equipment, and therefore all businesss of networking and speech business are all real-time.
Fig. 9 is the speech business transfer process figure according to the embodiment of the present invention, comprises following step:
The speech conversion of correspondent and after connecting with the transducer corresponding to described household electrical appliance, is digital signal through power line transmission to transducer corresponding to user place household electrical appliance by step 901: terminal " is answered " in execution control command;
Step 902: described transducer, by filtering and noise reduction, demodulation, recovers the digital signal that power line transmits, described digital signal is again through D/A conversion, electricity/sound conversion, and being transformed into user can hear voice;
Step 903: in communication process, described transducer by the speech conversion of user be digital signal by power line transmission to terminal;
Step 904: the digital signal of reception, in communication process, is sent to correspondent by terminal;
Step 905: work as end of conversation, terminal wait a period of time does not receive the digital signal that the transducer corresponding to household electrical appliance transmits, and namely determines end of conversation, so far automatically hangs up the telephone.
Figure 10 is the schematic diagram placed in the different room of family from transducer according to the terminal of the embodiment of the present invention, as shown in Figure 10, when transmission network of the present invention is electric power networks, all household electrical appliance under only supporting same ammeter in all rooms are interconnected, because power line transmission signals can not stride across ammeter, so electric equipment cannot realize interconnected between different ammeter, therefore fail safe improves greatly.Because each room power line is all intercommunication, as long as within the scope of same ammeter, terminal can be placed on any room, the outlet on any household electrical appliance side can be inserted, transducer is inserted on other household electrical appliance sides, such terminal just can one to one or one-to-many control multiple household electrical appliance, also can with certain household electrical appliance voice call, and multiple household electrical appliance business of networking can be realized.
The above, be only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention, and all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
