The invention provides a voice equipment awakening method based on an equipment network.
Specifically, the device network is created based on a wireless communication mode, for example, a WiFi local area network, a ZigBee network, or a bluetooth mesh network. The device network comprises a voice device serving as a master node (master node) and more than two voice devices serving as slave nodes (slave nodes). There is only one master node, and each node maintains information of all nodes in the network and marks which one is the master node. For example, each node maintains a node list in which information of all nodes in the device network is stored and marked as master nodes. The inventive method can be implemented in each speech device in the device network.
Fig. 1 is a schematic method diagram of an embodiment of a method for waking up a voice device based on a wireless local area network according to the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the voice device wake-up method at least includes step S110 and step S120.
Step S110, when the voice device is the slave node, when receiving the wake-up command, sending an arbitration request to the voice device as the master node, and determining the device responding to the wake-up command in the more than two voice devices as the slave nodes according to the arbitration request by the voice device as the master node.
Specifically, the arbitration request may include distance information between the voice device and a sound source of the wake-up command and/or sound energy information of the wake-up command received by the voice device. When the voice device serves as a slave node, when a wake-up command is received, the voice energy of the received wake-up command (wake-up voice) is acquired, and an arbitration request containing voice energy information is sent to the voice device serving as a master node; or calculating the distance between the voice equipment and the sound source of the awakening command according to the sound energy, and sending an arbitration request containing the distance to the voice equipment serving as the master node. The voice device serving as the master node determines, according to the sound energy information in the arbitration request sent by the voice devices serving as the slave nodes, a device that responds to the wake-up command among the voice devices serving as the slave nodes, for example, the sound energy may be compared, and the slave node device that has the larger sound energy of the received wake-up command is determined to respond to the wake-up command; or, the voice device serving as the master node determines, according to distance information in the arbitration request sent by the two or more voice devices serving as the slave nodes, a device that responds to the wake-up command in the two or more voice devices serving as the slave nodes, for example, the distance may be compared, and the slave node device closest to the sound source of the wake-up command may be determined to respond to the wake-up command. Under the condition that the voice device belongs to the slave node, after receiving a wake-up command and sending an arbitration request to the voice device serving as the master node, receiving an arbitration result of a device responding to the wake-up command in the more than two voice devices serving as the slave nodes determined by the voice device serving as the master node according to the arbitration request, wherein the arbitration result comprises a device identifier, such as an MAC (media access control) address, of the device responding to the wake-up command, and if the voice device belongs to the slave node, responding to the wake-up command, namely the voice device is woken up.
Step S120, in a case that the voice device to which the slave node belongs is a master node, receiving an arbitration request sent by the more than two voice devices serving as slave nodes in the device network, and determining, according to the arbitration request, a device responding to the wake-up command in the more than two voice devices serving as slave nodes.
And when the device serves as a master node, receiving an arbitration request sent by the more than two voice devices serving as slave nodes in the device network, wherein the arbitration request may include distance information between the voice device and a sound source of the wake-up command and/or sound energy information of the wake-up command received by the voice device. The voice device serving as the master node determines, according to the sound energy information in the arbitration request sent by the voice devices serving as the slave nodes, a device that responds to the wake-up command among the voice devices serving as the slave nodes, for example, the slave node device that has a larger sound energy and receives the wake-up command may compare the sound energy; or, the voice device serving as the master node determines, according to distance information in the arbitration request sent by the two or more voice devices serving as the slave nodes, a device that responds to the wake-up command in the two or more voice devices serving as the slave nodes, for example, the distance may be compared, and the slave node device closest to the sound source of the wake-up command may be determined to respond to the wake-up command. And under the condition that the voice equipment belongs to the master node, after the equipment responding to the awakening command in the more than two voice equipment serving as the slave nodes is determined, sending an arbitration result to the more than two voice equipment serving as the slave nodes, responding to the awakening command by the determined equipment responding to the awakening command, keeping other equipment in a state to be awakened, wherein the arbitration result comprises equipment identification (such as an MAC (media access control) address) of the equipment responding to the awakening command, the voice equipment serving as the slave nodes determines whether the voice equipment is the equipment responding to the awakening command according to the equipment identification, and if the voice equipment is the equipment responding to the awakening command, the voice equipment responds to the awakening command, namely is awakened.
In one embodiment, the device network is created by;
after the nodes are started, if the affiliated voice equipment does not receive the master signaling within the first preset time, the affiliated voice equipment becomes the master node and broadcasts the master signaling; if the master signaling started by the node is received within the first preset time, the voice equipment becomes a slave node, records the master node information, and broadcasts the corresponding networking signaling.
Specifically, the wireless communication mode includes, for example, a WiFi local area network, a ZigBee network, and a bluetooth mesh network. For example, all voice devices to be networked access the same wireless local area network. Wherein, each node (voice device) in the device network can be started by any voice device in the device network, i.e. the function realized by the present invention is started. For example, a user starts each node in the network by issuing a node start command (for example, including a voice command or a key command) to any voice device, the voice device receiving the start command broadcasts and sends a node start signaling through the local area network, and each voice device in the device network (including the voice device sending the node start master signaling) receives the node start signaling.
When any voice device receives the node starting signaling, the node starting signaling is used as a node, when the node is started, all nodes in the network are started as slave nodes, after any node is started, the master signaling is received, and the master signaling is networking signaling sent by the device which becomes the master node and indicates that the device becomes the master node; if the master signaling is not received within the first preset time, which indicates that no master node exists, the master node is actively changed into the master node, and the master signaling is broadcasted to indicate that the master node is changed into the master node, wherein the master signaling comprises the equipment identification (such as the MAC address) of the master node, and at this time, the network creation is successful. If the master signaling is received in the first preset time, which indicates that the master node is generated, any voice device continues to serve as the slave node, records the information of the master node, and broadcasts the networking signaling, wherein the networking signaling broadcasted by the slave node includes the device identifier (such as the MAC address) of the slave node.
After the voice device becomes a master node or a slave node, if a networking signaling of a newly added node is received, adding the node information of the newly added node into a node list of the voice device. For example, if any voice device receives the master signaling started by the node within the first preset time, the voice device continues to serve as a slave node, records the information of the master node, and broadcasts the networking signaling. Other node devices in the network receive the networking signaling of the node, and add the node as a new node into their own node list, for example, add the device identifier of the node into their own node list.
Further, for each node in the node list of the voice device, judging whether the interval time between the time when the heartbeat information of the node is received last time and the current time exceeds a second preset time; and if the interval time is judged to exceed the second preset time, deleting the node from the node list of the voice equipment.
Specifically, each node in the network traverses each node in its own node list, determines the interval duration between the time when the heartbeat information of the node is received last and the current time, and if the interval duration exceeds a preset specified time (i.e., the second preset time), the node is considered to be out of date and possibly have a fault, and the node is removed from the node list.
Further, there are several master node change cases as follows;
(1) and if the master node is deleted from the node list of the voice equipment and the master signaling is not received within the third preset time, the voice equipment becomes the master node.
For example, the slave node removes the MASTER node in the traversal process, and does not receive a new MASTER signaling within a certain time after the MASTER node is removed, that is, no node becomes the MASTER node, the MASTER node is actively changed to the MASTER node, and the MASTER signaling is sent to inform other nodes that the node becomes the new MASTER node. And if the master signaling is received in the third preset time, namely other nodes become master nodes, marking the node which sends the master signaling as the master node in the node list of the affiliated voice equipment. Other nodes detect that the heartbeat of the main node is overtime, and actively become a new main node, so that the normal response execution of the awakening command cannot be influenced.
(2) If the voice equipment is a slave node and the node list of the voice equipment marks that the first node is a master node, if a master signaling sent by the second node is received, judging whether the interval time of sending heartbeat information by the first node exceeds fourth preset time; and if the interval time exceeds the fourth preset time, marking the second node as a master node in a node list of the voice equipment.
For example, if the slave node marks that the node a is a MASTER node, the slave node receives MASTER signaling from the node B, and at this time, the slave node checks whether the heartbeat of the node a expires, and if so, the node B is marked as the MASTER node by updating, and the node B may be, for example, the node that is actively changed to the MASTER node in the case of the above (1), and broadcasts the MASTER signaling to notify other nodes after the node is actively changed to the MASTER node.
(3) When the voice equipment belongs to the master node, if master signaling from other nodes is received, comparing the size relationship between the MAC address of the voice equipment and the MAC address in the master signaling; and if the MAC address of the voice equipment is larger than the MAC address in the master signaling, the voice equipment is changed into a slave node.
For example, after the node is started, there may be more than two nodes that do not receive the master signaling within the first preset time, and the more than two nodes that do not receive the master signaling within the first preset time may simultaneously become master nodes, resulting in a master node conflict. If the MASTER node receives the MASTER signaling from other equipment (namely, the MASTER node conflicts), the MAC address of the MASTER node is compared with the MAC address in the MASTER signaling (character string comparison), if the MAC address in the MASTER signaling is smaller, the MASTER node is actively changed into the slave node, the MASTER node which is executing the arbitration task is not switched when meeting the MASTER conflict, and the MASTER node is switched after the task is completed.
Fig. 2 is a schematic diagram of a change process of a node role according to an embodiment of the present invention. As shown in fig. 2, after a node is started, if no MASTER signaling is received in 3 heartbeats, the node becomes a MASTER node, and if the MASTER signaling is received in 3 heartbeats, it indicates that another device has become a MASTER node, the node becomes a slave node. And after the MASTER node becomes the slave node, if the heartbeat of the MASTER node is overtime, the MASTER node is removed, and if 3 heartbeats do not receive the MASTER signaling, the MASTER node becomes the slave node.
The invention provides a voice equipment awakening device based on an equipment network.
Specifically, the device network is created based on a wireless communication mode, for example, a WiFi local area network, a ZigBee network, or a bluetooth mesh network. The device network comprises a voice device serving as a master node (master node) and more than two voice devices serving as slave nodes (slave nodes). There is only one master node, and each node maintains information of all nodes in the network and marks which one is the master node. For example, each node maintains a node list in which information of all nodes in the device network is stored and marked as master nodes. The inventive arrangement may be implemented in each speech device in the network of devices.

Specifically, the arbitration request may include distance information between the voice device and a sound source of the wake-up command and/or sound energy information of the wake-up command received by the voice device. When the voice device is used as a slave node, when the first receiving unit 110 receives a wake-up command, the sound energy of the received wake-up command (wake-up voice) is obtained, and the sending unit 120 sends an arbitration request containing sound energy information to the voice device used as a master node; or calculating the distance between the voice equipment and the sound source of the awakening command according to the sound energy, and sending an arbitration request containing the distance to the voice equipment serving as the master node.

If the master signaling is received in the first preset time, which indicates that the master node is generated, any voice device continues to serve as the slave node, records the information of the master node, and broadcasts the networking signaling, wherein the networking signaling broadcasted by the slave node includes the device identifier (such as the MAC address) of the slave node.
After the voice device becomes a master node or a slave node, if a networking signaling of a newly added node is received, adding the node information of the newly added node into a node list of the voice device. For example, if any voice device receives the master signaling started by the node within the first preset time, the voice device continues to serve as a slave node, records the information of the master node, and broadcasts the networking signaling. Other node devices in the network receive the networking signaling of the node, and add the node as a new node into their own node list, for example, add the device identifier of the node into their own node list.
Further, for each node in the node list of the voice device, judging whether the interval time between the time when the heartbeat information of the node is received last time and the current time exceeds a second preset time; and if the interval time is judged to exceed the second preset time, deleting the node from the node list of the voice equipment.
Specifically, each node in the network traverses each node in its own node list, determines the interval duration between the time when the heartbeat information of the node is received last and the current time, and if the interval duration exceeds a preset specified time (i.e., the second preset time), the node is considered to be expired, and the node is removed from the node list.
Further, there are several master node change cases as follows;
(1) and if the master node is deleted from the node list of the voice equipment and the master signaling is not received within the third preset time, the voice equipment becomes the master node.
For example, the slave node removes the MASTER node in the traversal process, and does not receive a new MASTER signaling within a certain time after the MASTER node is removed, that is, no node becomes the MASTER node, the MASTER node is actively changed to the MASTER node, and the MASTER signaling is sent to inform other nodes that the node becomes the new MASTER node. And if the master signaling is received in the third preset time, namely other nodes become master nodes, marking the node which sends the master signaling as the master node in the node list of the affiliated voice equipment.
(2) If the voice equipment is a slave node and the node list of the voice equipment marks that the first node is a master node, if a master signaling sent by the second node is received, judging whether the interval time of sending heartbeat information by the first node exceeds fourth preset time; and if the interval time exceeds the fourth preset time, marking the second node as a master node in a node list of the voice equipment.
For example, if the slave node marks that the node a is a MASTER node, the slave node receives MASTER signaling from the node B, and at this time, the slave node checks whether the heartbeat of the node a expires, and if so, the node B is marked as the MASTER node by updating, and the node B may be, for example, the node that is actively changed to the MASTER node in the case of the above (1), and broadcasts the MASTER signaling to notify other nodes after the node is actively changed to the MASTER node.
(3) When the voice equipment belongs to the master node, if master signaling from other nodes is received, comparing the size relationship between the MAC address of the voice equipment and the MAC address in the master signaling; and if the MAC address of the voice equipment is larger than the MAC address in the master signaling, the voice equipment is changed into a slave node.
For example, after the node is started, there may be more than two nodes that do not receive the master signaling within the first preset time, and the more than two nodes that do not receive the master signaling within the first preset time may simultaneously become master nodes, resulting in a master node conflict. If the MASTER node receives the MASTER signaling from other equipment (namely, the MASTER node conflicts), the MAC address of the MASTER node is compared with the MAC address in the MASTER signaling (character string comparison), if the MAC address in the MASTER signaling is smaller, the MASTER node is actively changed into the slave node, the MASTER node which is executing the arbitration task is not switched when meeting the MASTER conflict, and the MASTER node is switched after the task is completed.
