First embodiment of the present invention relates to a kind of intelligent domestic system.The block diagram of this intelligent domestic system and terminal interaction as shown in Figure 1.Wherein, this intelligent domestic system comprises N number of Smart Home node, and the terminal mutual with this intelligent domestic system has F, M, N, E, F be not less than 1 natural number, and M is not more than N, and E is not more than F.Terminal, by carrying out with a Smart Home node access that data interaction realizes whole intelligent domestic system, carries out information interaction by mesh network fast and stable between Smart Home node.Smart Home node can be telepilot, switch, lamp, sensor, TV, air-conditioning, washing machine, watch-dog, refrigerator etc.; Terminal can be mobile phone, flat board etc., and Smart Home node and terminal are not limited to the above citing, will not enumerate here.
In present embodiment, each Smart Home node has broadcast listening state and connection status, Smart Home node when broadcast listening state for sending broadcast packet, and monitor other Smart Home nodes send information; Smart Home node when connection status, also for receive and forward terminal packet and monitor other Smart Home nodes send information.Under two states, Smart Home node can forward the information that receives or this node state with broadcast mode and change the information that the needs that cause send.Smart Home node and terminal adopt Bluetooth Low Energy (BLE) agreement to carry out data communication, and concrete communication mode does not limit the above, repeats no longer one by one here.
Bluetooth Low Energy (BLE) agreement adopts two kinds of communication channels when carrying out data interaction: broadcast channel and data channel; In Bluetooth Low Energy (BLE) agreement more than 4.0 version, there are 3 broadcast channels and 37 data channels, Smart Home node can be broadcasted at 3 broadcast channels, and the subset of 3 broadcast channels or 37 data channels or these channels carries out monitoring and forwarding.Smart Home node can send broadcast packet at least one broadcast channel, at least one broadcast or data channel is monitored the information that other Smart Home nodes send, receives and forwarding data bag.In the present embodiment, be described for 3 broadcast channels and 4 data channels, but the number of communication channel as limit, can freely should not selected according to actual needs.
Specifically, broadcast packet comprises specific broadcast data, and wherein whether this broadcast data comprises for illustration of this Smart Home node only to the information that the equipment of specifying sends, and also comprises for determining whether this Smart Home node is attachable information.Packet comprises the information such as identify label number and ciphertext of various control command, Intelligent target home node.The particular content of broadcast packet and packet is not limited to the above, can sets itself according to actual needs.
When Smart Home node is in broadcast listening state, according to the time slot preset, send the information that broadcast packet and other Smart Home nodes of monitoring and terminal send.Such as, as shown in Figure 2, A1, A2, A3 are 3 broadcast channel time slots, D1, D2, D3, D4 are 4 data channel time slot, broadcast packet is sent at front 3 time slots in each cycle, broadcast message is herein convenient to initiate connection request to Smart Home node after smart machine receives, such as follow the broadcast packet form (Advertising PDU) of Bluetooth Low Energy (BLE) agreement, after smart machine receives broadcast packet, connection request bag (Connection Request) can be sent and connect; Rear 4 time slots monitor 4 data channels respectively, for the control of Mesh network and status information mutual, expand such as, inside the broadcast packet form that can be mounted in Bluetooth Low Energy (BLE) agreement or to it.Just illustrate at this, the mode presetting time slot is not limited thereto, can sets itself according to the actual requirements.In addition, Smart Home node broadcasts and monitoring can use identical channel, such as, in a kind of implementation, can using A1 ~ A3 when broadcasting, also can use A1 ~ A3 when monitoring; In another kind of implementation, only broadcast channel A1 can be used when broadcasting, the reception of a monitored data channel D1 and every secondary data only usage data channel D1 when monitoring, the determination mode of the channel that broadcast and monitoring use is not limited to the above, repeats no longer one by one here.
Smart Home node listens to data under broadcast listening state, when namely receiving data, at least one data channel utilizes fixing time slot relation forward the information listened to, has forwarded rear Smart Home node and be again switched to broadcast listening state.Such as, as shown in Figure 3, wherein, the Smart Home node receiving data by data channel D1 in the n-th cycle can interrupt broadcast listening circulation at once, enter forward mode, at D1 ~ D4 channel cocycle forwarding data, after being cycled to repeat one or many, intelligent node comes back to the normal broadcast listening state shown in Fig. 2.In addition, when forwarding, the length used in slot length Fig. 2 that each channel uses may be different, and slot length is set to certain value, so that other nodes be in Fig. 2 circulation can receive data within the time of a circulation.Concrete pass-through mode is not limited to the above, can determine according to actual conditions.
Smart Home node can send one or many broadcast packet respectively an airtime in each broadcast channel, owing to having preset effective time slot, has avoided multiple terminal and sends connection request at one time and the data collision caused.Terminal scanning function is opened, when terminal is when the broadcast coverage interscan of Smart Home node is to this Smart Home node, terminal sends connection request, and Smart Home node responds this connection request, connect with terminal, and be switched to connection status from broadcast listening state; When Smart Home node and terminal disconnect, Smart Home node is switched to broadcast listening state from connection status.As shown in Figure 4, when intelligent terminal node and terminal connect, intelligent terminal node is switched to connection status from broadcast listening state in the state transfer of Smart Home node; When intelligent terminal node and terminal connect, intelligent terminal node is switched to broadcast listening state from connection status.In addition, Smart Home node, when listening to the information that other Smart Home nodes send, at least one data channel utilizes fixing time slot relation forward the information listened to, has forwarded rear Smart Home node and be again switched to broadcast listening state.Smart Home node, in connection status, when needs forwarding data bag, carrying out the interval of data interaction with terminal, forwarding this packet, and after forwarding completes, being again switched to connection status.
In addition, what deserves to be explained is, when Smart Home node is in connection status, for receiving and forward the packet of terminal.A Smart Home node can be connected with multiple terminal, also can only be connected with a terminal.When a Smart Home node is connected with terminal, this Smart Home node can be broadcasted, and also can not broadcast.When not broadcasting, only usage data channel carries out reception and the forwarding of packet, and concrete schematic diagram as shown in Figure 5.
Smart Home node, when connection status, also can monitor information or the forwarding data bag of other Smart Home nodes transmission.Now, Smart Home node receives the packet of self terminal every the set time, and the interval received, at least one data channel utilizes fixing time slot relation, forwarding data bag or monitor the information that other Smart Home nodes send.As shown in Figure 6, data interaction is carried out at data channel D (can be any one in D1 ~ D4) with terminal every regular time, in the interval of data interaction, by monitoring D1 ~ D4, or at D1 ~ D4 forwarding data, for Bluetooth Low Energy Physical layer, when namely D corresponds to each connection interval (Connection Interval), intelligent node and smart machine mutual, the transmission on D1 ~ D4 is then carried out with other Smart Home nodes for realizing alternately.
Smart Home node except broadcast listening state send broadcast packet or monitor other Smart Home nodes send information, or outside the packet receiving and forward terminal in connected state, also there is the situation needing to send packet, that is, Smart Home node independently sends information at needs.Such as some button of telepilot is pressed or intelligent switch is pressed, now telepilot or intelligent switch need these control commands be pressed to send as Smart Home node; Smart Home node, when receiving the packet needing to provide response, needs response message to send.Now, no matter Smart Home node is in broadcast listening state or connection status, and directly at least one data channel, can forward the information that need send according to forwarding time slot, after having forwarded, Smart Home node is switched to previous status again.
Smart Home node judges whether to need to respond this packet, and concrete judgment mode illustrates by way of example.Include identify label number and the group identification number of Smart Home node in the packet that terminal sends, this identify label number may be used for uniquely determining Smart Home node, and this group identification number may be used for determining unique Smart Home node belonging to this group.Smart Home node by by the identify label of self number or group identification number and the identify label in the packet of reception number with organize identification number and contrast, if identify label number or group identification number identical, then this Smart Home node responds this packet, and forwards to this packet and to the response of this packet simultaneously; If identify label number is different from group identification number, then this Smart Home node does not respond this packet, and forwards this packet simultaneously.The concrete judgment mode of Smart Home node is not limited thereto, and repeats no longer one by one here.
Conveniently understand, can especially by illustrating above-mentioned intelligent domestic system, as shown in Figure 7, Smart Home node is telepilot and 7 lamps (lamp 11, lamp 12, lamp 21, lamp 22, lamp 23, lamp 24, lamp 31), and terminal is mobile phone.Generally, 7 lamps are in broadcast listening state.Suppose at a time, user presses the button of telepilot, sends the control command of " turning on light " to lamp 31.
