Bluetooth nodes equipment is communicated with voice controller by bluetooth Mesh network, according to reception Mesh data or its own
Key-press event carry out response operation.
Preferably, each voice controller acquires voice, carries out voice de-noising and echo cancellation, and it is local then to carry out voice
Or online recognition, semantic understanding parse the information to be controlled, and are packaged into Mesh data, are sent to Mesh by bluetooth module
In network.
Preferably, each voice controller further includes a wifi module.
The present invention also provides the control method of above-mentioned control system, concrete methods of realizing is as follows:
The configuration of Mesh network is carried out configuring each device node by mobile phone app and be networked, mobile phone configuration Mesh net
Network process is as follows:
(1) app creates a Mesh network；
(2) Mesh network node is searched for；
(3) voice controller is added, location information, such as master bedroom are set, and are automatically set as agent node；
(4) smart machine is added, then location information, such as parlor are set；
(5) it is such as switched, socket, lamp etc. to the smart machine of addition according to the information of distinct device, gives its name；
(6) configured new bluetooth device configuration information is saved in " voice controller "；
(7) as above, remaining smart machine and voice controller are successively added；
(8) one equipment of every addition acts on behalf of voice controller node configuration data and passes through broadcast synchronization to other voices
Controller；
(9) speech control system configuration is completed, and user can delete or modify any one equipment, any modification of app
Movement all can real-time synchronization to relevant device and voice controller.
Using technical solution of the present invention, have the advantages that
(1), device independence: any one device node is all mutually indepedent, if some device node extremely will not shadow
Other device nodes are rung to work normally；
(2), distributed sound controls: more voice entrance, any one voice controller can set other of network
Slave node carries out voice control, controls compared to previous mobile phone app, more intelligently；
(3), using bluetooth Mesh agreement, each device node has relaying and forwarding capability, and wireless transmission distance is farther,
Networking capability compares other wireless protocols, more powerful；
(4), mobile phone is directly connected to, and is not necessarily to additional gateway；
(5), using bluetooth technology with low power consumption, other wireless technologys are compared, power consumption is lower.
(6), at low cost.
Detailed description of the invention
Fig. 1 is that the embodiment of the present invention uses networking diagram；
Fig. 2 is speech path controller data synchronization principles flow chart (agent equipment) of the present invention；
Fig. 3 is speech path controller data synchronization principles flow chart (non-proxy equipment) of the present invention.
Specific embodiment
Networking referring to Fig.1, for example, master bedroom, secondary room, parlor, balcony, toilet, dining room etc. equipped with speech path controller and
Blue-tooth intelligence equipment (switch or socket), bluetooth Mesh networking can communicate with each other between equipment.
Wherein, voice controller: including voice collecting, voice de-noising, speech recognition and bluetooth module, wifi module
(optional), in speech input interface, by voice collecting, voice de-noising, speech recognition, semantic understanding parses to control and sets
Standby information, if socket controls, lamp control etc., the data being then packaged as in Mesh network are sent by bluetooth module；
Blue-tooth intelligence equipment: by the data received, control instruction is identified, to come control switch and socket.
It is speech path controller data synchronization principles flow chart (agent equipment) of the present invention referring to Fig. 2.A certain voice control
Device receives mesh data, later synchronous configuration data to other all voice controllers, whether judging that synchrodata receives completely
(for the first time completely judgement), when feedback synchronization successful respond again completely；When incomplete, then keep receiving data, continue to,
Mesh data (branch 1) is received on one side, continues synchronization request (branch 2) at the same time；For branch 1, then continue synchronous configuration
Data, whether then receiving the data of loss before tables of data, then judge that synchrodata receives completely (second of judgement completely),
Complete judgment step for the first time is returned if completely, if not exclusively, the holding before return branch 1 and 2 receive data & after
The step of continued access is received.
Synchronous by speech path controller data shown in Fig. 2, each speech path controller in the present invention may be implemented mutually
Independent related communication again, synchronizing is based on related communication, after synchronous, so that it may bluetooth nodes equipment in independent control network.
It is speech path controller data synchronization principles flow chart (non-proxy equipment) of the present invention, at this point, voice control with reference to Fig. 3
Device sheet processed is as agent node.The modification configuration of mobile phone app first, sets agent node for a certain voice controller, and keep
Configuration data then judges whether there is other voice controllers, if without same the end of the step is jumped directly to；Broadcast is carried out if having to match
Table data step is set, later, continues synchronous transmission response request, same the end of the step is jumped to if unresponsive, if there is response to sentence
It is disconnected whether time-out, jump directly to step broadcast configuration table data not overtime, it is overtime then jump to same the end of the step.
Based on Fig. 3, the present invention also provides a kind of control method of above-mentioned control system, concrete methods of realizing is as follows:
The configuration of Mesh network is carried out configuring each device node by mobile phone app and be networked, mobile phone configuration Mesh net
Network process is as follows:
(1) app creates a Mesh network；
(2) Mesh network node is searched for；
(3) voice controller is added, location information, such as master bedroom are set, and are automatically set as agent node；
(4) smart machine is added, then location information, such as parlor are set；
(5) it is such as switched, socket, lamp etc. to the smart machine of addition according to the information of distinct device, gives its name；
(6) configured new bluetooth device configuration information is saved in " voice controller "；
(7) as above, remaining smart machine and voice controller are successively added；
(8) one equipment of every addition acts on behalf of voice controller node configuration data and passes through broadcast synchronization to other voices
Controller；
(9) speech control system configuration is completed, and user can delete or modify any one equipment, any modification of app
Movement all can real-time synchronization to relevant device and voice controller.
Based on described above, the main innovation of the present invention is the following aspects:
