Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 schematically shows an alternative example of the bluetooth Mesh network, and as shown in fig. 1, the bluetooth Mesh network may include: a plurality of Node devices 101 of a distributed network. In fig. 1, a bluetooth Mesh gateway 102 and a terminal Device 103 are used as control devices, and besides adding a Device (un-provisioned Device) 104 that is not connected to a bluetooth Mesh network through a Provisioning process, the bluetooth Mesh gateway can also configure and control a node Device that has been connected to a network.
The node device 101 may be regarded as a bluetooth Mesh device that has joined a bluetooth Mesh network; the device 104 not connected with the network can be regarded as a bluetooth Mesh device which is not connected with the bluetooth Mesh network; the bluetooth Mesh gateway 102 may be, for example, a smart speaker, a multi-mode gateway, etc. with bluetooth communication capability and internet connection capability; the terminal device 103 may be a user-side device such as a smart phone or a tablet computer used by a user, and has the configuration and control functions of the node device 101, the function of controlling the node device 101 through the bluetooth Mesh gateway 102, and the like. It can be understood that after the non-distribution network device 103 is connected to the bluetooth Mesh network, the non-distribution network device 103 may become a node device in the bluetooth Mesh network, and a user may implement security control on the node device 101 in the bluetooth Mesh network through the bluetooth Mesh gateway 102 and/or the terminal device 103.
In the process of implementing safety control on the node device 101 in the bluetooth Mesh network by the bluetooth Mesh gateway 102 and/or the terminal device 103, the control and device state monitoring on the node device can be implemented by the bluetooth Mesh gateway and/or the terminal device, so as to ensure the user experience of fast and continuous control on the node device, and the device state of each node device can be presented to the user within a certain time. Specifically, the bluetooth Mesh gateway 102 and/or the terminal device 103 may send a broadcast packet to the node device, and if there is an instruction that the node device needs to reply in the broadcast packet, the node device sends a state synchronization message to the bluetooth Mesh gateway and/or the terminal device based on the content of the broadcast packet, where the node device may send the state synchronization message to the bluetooth Mesh gateway and/or the terminal device according to a message sending parameter, and the message sending parameter may be, for example, a state synchronization period of the node device, retransmission times of message sending and Relay, a time range of multicast state reply, a synchronization state delay range of the powered device, and the like.
It should be noted that, there may be a plurality of node devices in the bluetooth Mesh network, so that the number of node devices to be controlled may be multiple, and the target node device to be controlled at one time may also be multiple. Taking a bluetooth Mesh gateway To control N node devices as an example, when N =1, the bluetooth Mesh gateway controls one node device, that is, in a single-control scenario, the data transmission amount is limited, the bluetooth Mesh gateway broadcasts a control message, and the node device can send a state return message To the bluetooth Mesh gateway, where each message may correspond To different data transmission amounts according To different message sending parameters such as TTL (Time To Live) and broadcast Relay retransmission times when sending the message; when N is greater than 1, the bluetooth Mesh gateway controls a plurality of node devices, that is, under a group control scenario, at this time, a direct relationship exists between the data transmission amount and the number of the node devices, the bluetooth Mesh gateway broadcasts a control message, and the N node devices can send N state return messages to the bluetooth Mesh gateway, wherein each message can correspond to different data transmission amounts according to message sending parameters such as TTL and broadcast Relay retransmission times when the node devices send the messages.
However, under the condition that the number of bluetooth Mesh devices in a large-scale bluetooth Mesh network is hundreds, if a plurality of node devices simultaneously send messages to the control device, data collision may occur, which may cause congestion of the bluetooth Mesh network, resulting in that the control device may not receive the messages sent by all the node devices in time, thereby increasing the packet loss rate and affecting the control experience of the user. Therefore, it is necessary to set the message transmission parameters of the node apparatus. As an alternative implementation, random delay of 20-500 milliseconds can be made before each node device sends the message, so as to avoid data collision of a plurality of node devices. However, the inventor finds that the method can achieve the effect of avoiding collision under the condition that the number of the node devices in the bluetooth Mesh network is small, and a large number of transmission collisions still exist in the large-scale bluetooth Mesh network with a large number of node devices. As another optional implementation, a mode of polling and reading the state of the node device by the control device may be used to control all node devices in the bluetooth Mesh network, but based on this mode, the inventor finds that the control device in the bluetooth Mesh network may control multiple node devices, and when the control device needs to control a larger number of node devices, the control device needs to frequently send broadcast packets, and frequently sending broadcast packets may affect messages sent by the receiving node device, so that a mode of polling and reading the state of the device is used, and based on the limitation of the number of node devices supported by a single control device, user experience may also be affected.
Therefore, in the bluetooth Mesh network, it is very important how to reasonably set the message sending parameters of the node device to adapt to the network condition of the bluetooth Mesh network. Based on this, through an improved technical scheme, in the bluetooth Mesh network, the message sending parameters of the node devices are dynamically and adaptively adjusted based on the number of the node devices in the bluetooth Mesh network, so that the message sending parameters of the node devices can adapt to the network scale condition of the bluetooth Mesh network, and the message sending parameters of the node devices are reasonably set; meanwhile, because the message sending parameters of the node equipment influence the bandwidth and the flow of the Bluetooth Mesh network, under the condition of reasonably setting the message sending parameters of the node equipment, the bandwidth and the flow of the Bluetooth Mesh network can be optimized, and the blocking condition of the Bluetooth Mesh network is reduced.
Based on the above-mentioned idea, fig. 2 exemplarily shows an optional flowchart of a setting method of a message sending parameter provided in an embodiment of the present application. The method flow may be executed by the control device (including the bluetooth Mesh gateway or the terminal device) and the node device (i.e. the configured bluetooth Mesh device), and referring to fig. 2, the method flow may include the following steps.
Step S211, the control device sends a first broadcast packet to the node device in the Bluetooth Mesh network, wherein the first broadcast packet is used for setting a first message sending parameter for the node device.
The first broadcast packet in the embodiment of the present application may be used to set a first message sending parameter for the node device, so that the control device can obtain a state synchronization message of the node device in time, and control the node device is implemented. The first message sending parameter may be, for example, a state synchronization period of the node device, retransmission times of message sending and Relay, a time range of multicast state reply, a synchronization state delay range of the powered device, and the like.
Step S212, the node device acquires the first broadcast packet, and sets a first message sending parameter according to the first broadcast packet.
Step S213, the node device sends a message according to the first message sending parameter.
Step S214, the control device obtains the message sent by the node device according to the first message sending parameter; and determining the number of the node devices in the Bluetooth Mesh network according to the message sent by the node devices.
In some embodiments, the first broadcast packet sent by the control device to the node device may include an instruction that the node device needs to return a message, so as to obtain the state of the node device in time, or may include an instruction that the node device does not need to return a message, and then the first broadcast packet may be used as a one-way notification broadcast packet. When the first broadcast packet contains an instruction that the node device needs to return the message, the node device needs to return the message to the control device according to the first message sending parameter, so that the control device can acquire the message sent by the node device according to the first message sending parameter, and determine the number of the node devices in the bluetooth Mesh network according to the message sent by the node device.
It should be noted that the message sent by the node device acquired by the control device may be attribute information of the node device, for example, if the node device is a lamp, the message sent by the node device includes attribute values of a switch, brightness, color temperature, and the like of the lamp, where the message sent by the node device may be sent according to a certain format, for example, the format of the message may be compliant with a bluetooth Mesh model, and each node device sends a message including the attribute information thereof to the control device, and if the node device includes more attribute information, the content to be transmitted may exceed one segment, so the attribute information of the node device may be compressed in one segment for sending.
In some further embodiments, the message sent by the node device includes address information of the node device, where the address information may be information uniquely identifying the node device, such as a unicast address. As an optional implementation, the control device may determine, according to the message sent by the node device, the address information of the node device, so as to record the address information, perform statistics on the recorded address information, determine the number of the address information, and determine, according to the determined number of the address information, the number of the node devices in the bluetooth Mesh network.
It should be noted that, when the control device sends the broadcast packet to the node device according to a certain time period, the address information of the node device that sends the message, which is recorded in the time period, may be counted when the next time period arrives. Taking the bluetooth Mesh gateway as an example, the bluetooth Mesh gateway sends a first broadcast packet to the node device every 30 seconds, so that before the next 30 seconds arrive, the message sent by the node device with the first message sending parameter can be acquired, and the number of unicast addresses recorded in 30 seconds is counted, so as to determine the number of the node devices in the bluetooth Mesh network.
Step S215, the control device sends the second broadcast packet to the node device in the bluetooth Mesh network.
The second broadcast packet is used for setting a second message sending parameter for the node equipment, wherein the second message sending parameter is associated with the number of the node equipment, and the parameter value of the second message sending parameter is different from that of the first message sending parameter.
Step S216, the node device obtains a second broadcast packet, and sets a second message sending parameter according to the second broadcast packet.
Step S217, the node device sends a message according to the second message sending parameter.
In order to enable the first message sending parameters of the node devices to adapt to the network scale condition of the bluetooth Mesh network, the control device may generate a second broadcast packet based on the determined number of the node devices, and send the second broadcast packet to the node devices in the bluetooth Mesh network, so that the node devices set the second message sending parameters according to the second broadcast packet.
In some embodiments, the control device may determine whether the number of node devices changes by determining the number of node devices in the bluetooth Mesh network, where the change in the number of node devices may be obtained by comparing the number of node devices determined by the control device based on the message sent by the node device with the first message sending parameter, where the number of node devices is determined by the control device when sending the first broadcast packet. Therefore, when the number of the node devices changes, the first message sending parameters are correspondingly adjusted based on the determined number of the node devices in the Bluetooth Mesh network, and second message sending parameters suitable for the scale of the Bluetooth Mesh network are obtained, wherein parameter values of the second message sending parameters are obtained after adjustment, so that the parameter values can be different from parameter values of the first message parameters, and therefore, the second message sending parameters are associated with the number of the node devices based on the second message sending parameters, and reasonable configuration of the second message sending parameters is achieved. And under the condition of reasonably setting the second message sending parameters of the node devices, the control device can receive the messages sent by each node device and can hash in the time period, so that the collision probability of each node device can be effectively reduced, the minimum collision is realized in a large-scale Bluetooth Mesh network, the bandwidth and the flow of the Bluetooth Mesh network are optimized, and the blocking condition of the Bluetooth Mesh network is reduced.
It should be noted that, in some embodiments, the first broadcast packet may be a broadcast packet sent to all node devices in an initial state of the bluetooth Mesh network, so as to implement initialization of the node devices. In other embodiments, the first broadcast packet may also be a last broadcast packet used to adjust the messaging parameters of the node device.
As an alternative implementation, the second broadcast packet may be broadcast by the control device based on a preset time period, for example, after the control device broadcasts the first broadcast packet, if the time reaches the preset time period, the control device may broadcast the second broadcast packet.
In other possible implementations, the second broadcast packet may be broadcast based on a preset condition. The preset condition may be a condition that the control device senses that the number of the node devices is changed. In one example, the preset condition may be that the control device senses that a change value of the number of node devices reaches a preset value; the preset value can be a value of increasing or decreasing the number of node devices in the bluetooth Mesh network. For example, the embodiment of the application may determine a preset value that affects the bandwidth flow of the bluetooth Mesh network, that is, a variation value of the number of node devices reaches the preset value, which affects the bandwidth flow of the bluetooth Mesh network; therefore, after the control device broadcasts the first broadcast packet, if the change value of the number of the node devices is sensed to reach the preset value and the change of the number of the node devices has influence on the bandwidth flow of the Bluetooth Mesh network, the control device can broadcast the second broadcast packet to adjust the message sending parameters of the node devices.
In some embodiments, based on the control and monitoring of the control device on all the node devices in the bluetooth Mesh network, as an optional implementation, the second broadcast packet sent by the control device to the node device may include a second message sending parameter set for the node device, so that the node device can perform corresponding setting based on the obtained second message sending parameter in the second broadcast packet. As another optional implementation, based on that the second message sending parameter is associated with the number of node devices, the second broadcast packet sent by the control device to the node device may include the number of node devices, where the number of node devices is used to enable the node device receiving the second broadcast packet to set the second message sending parameter, so that the node device can correspondingly set the second message sending parameter based on the number of node devices in the obtained second broadcast packet.
It can be seen that, in the embodiment of the present application, based on the number of node devices in the bluetooth Mesh network determined by the control device, the message sending parameters of the node devices are dynamically and adaptively adjusted to obtain the second message sending parameters, so that the second message sending parameters of the node devices are adapted to the network scale condition of the bluetooth Mesh network, and the message sending parameters of the node devices are reasonably set; meanwhile, because the message sending parameters of the node equipment influence the bandwidth and the flow of the Bluetooth Mesh network, under the condition of reasonably setting the message sending parameters of the node equipment, the bandwidth and the flow of the Bluetooth Mesh network can be optimized, and the blocking condition of the Bluetooth Mesh network is reduced.
In some embodiments, a bluetooth Mesh gateway in a bluetooth Mesh network and a bluetooth Mesh device (including a node device that has been configured and a device that has not been configured) may interact by directly sending a broadcast packet, and a terminal device such as a smart phone or a tablet computer may establish Proxy connection with a node device in the bluetooth Mesh network because the terminal device does not support the interaction method of directly sending the broadcast packet, and forward the broadcast packet to other node devices in the bluetooth Mesh network by the node device serving as Proxy, so that message sending and Relay retransmission times corresponding to the node device need to be set, and the terminal device may send the broadcast packet to all node devices in the bluetooth Mesh network, and if all the node devices return messages to a control device, the node device may set a certain delay to the sent message, and the sending of the message to the terminal device by the node device may be implemented within a message sending period of the node device. Thus, the second message sending parameters may include at least a first type of parameter and a second type of parameter, where the first type of parameter may be a parameter associated with the number of message sending times of the node device, such as the number of retransmission times of the message sending and relay; the second type of parameter may be a parameter associated with a message sending time of the node device, such as a period of state synchronization, a time range of multicast state reply, a delay range of power device synchronization state, and the like.
In some further embodiments, based on that the first type of parameter in the pair of second message sending parameters is associated with the number of message sending times of the node device, the first type of parameter in the pair of second message sending parameters has a positive correlation with the number of node devices. Optionally, when the number of the node devices is increased, on the basis of the first message sending parameter, the first type parameter in the second message sending parameter is increased, and the increased first type parameter is greater than the first type parameter in the first message sending parameter, for example: the relay node equipment receives and forwards messages of other node equipment in the Bluetooth Mesh network, wherein if the number of the node equipment is increased, the messages of the node equipment which need to be received and forwarded by the relay node are increased, so that the message sending and relay retransmission times in the second message sending parameters corresponding to the relay node equipment are increased; when the number of the node devices is decreased, on the basis of the first message sending parameters, the first type parameters in the second message sending parameters are decreased, and the decreased first type parameters are smaller than the first type parameters in the first message sending parameters, for example: and the relay node equipment receives and forwards the messages of other node equipment in the Bluetooth Mesh network, wherein if the number of the node equipment is reduced, the messages of the node equipment which need to be received and forwarded by the relay node are reduced, so that the message sending and relay retransmission times in the second message sending parameters corresponding to the relay node equipment are reduced.
In some further embodiments, the second type of the second message sending parameters is in a negative correlation with the number of node devices based on the second type of the pair of the second message sending parameters being associated with the message sending time of the node device. Optionally, when the number of the node devices is increased, on the basis of the first message sending parameter, a second type parameter in the second message sending parameter is decreased, and the decreased second type parameter is smaller than the second type parameter in the first message sending parameter, for example: in the bluetooth Mesh network, when the number of node devices is increased, in order to enable the messages sent by all the node devices to be hashed in the time period of the control device, the period of state synchronization of each node device is reduced; when the number of node devices decreases, on the basis of the first message sending parameter, a second type parameter in the second message sending parameter increases, and the increased second type parameter is greater than a second type parameter in the first message sending parameter, for example: in the bluetooth Mesh network, when the number of node devices decreases, in order to enable all messages sent by the node devices to be hashed within the time period of the control device, the period of state synchronization of each node device increases.
It should be noted that, when the control device periodically sends the broadcast packet to each node device in the bluetooth Mesh network according to the broadcast period, the broadcast period based on the control device is fixed, so that the control device obtains the message sent by the node device according to the second message sending parameter, which may be random in the broadcast period of the control device, as long as it is ensured that the messages sent by the plurality of node devices do not generate data collision.
It should be further noted that the first message sending parameter may be selected within a default random delay range, so that during the broadcast period of the control device, an increased or decreased parameter value may be selected within a default parameter value range according to an increase or decrease of the number of node devices in the bluetooth Mesh network. Using the second type of parameters as an example, the Bluetooth alliance SIG Mesh Standard Mesh Profile
The Specification relates to that each node carries out 20-500 ms random delay before sending a packet, and the second type of parameter in the first message sending parameter can be a parameter value selected in a default range of 20-500 ms, so that when the number of node devices in the Bluetooth Mesh network is increased or decreased, the second type of parameter in the second message sending parameter can be selected in the random delay range of 20-500 ms to obtain the second type of parameter in the second message sending parameter, wherein when the number of the node devices is increased, the second type of parameter in the second message sending parameter is obtainedThe value of the second type of parameter is smaller than the value of the second type of parameter in the first type of parameter in the range; when the number of the node devices is reduced, the value of the second type of parameters in the second message sending parameters is larger than the value of the second type of parameters in the first type of parameters in the range. Further, when the increment of the node devices in the bluetooth Mesh network is large, the delay range of the message sending parameter can be correspondingly set according to the change of the number of the node devices in the network.
According to the embodiment of the application, the second message sending parameters are associated with the number of the node devices in the Bluetooth Mesh network, so that the set second message sending parameters can adapt to the network scale of the Bluetooth Mesh network, minimum data conflict is realized in a large-scale Bluetooth Mesh network, minimum delay is realized in a small-scale Bluetooth Mesh network, the bandwidth and the flow of the Bluetooth Mesh network are optimized, and the blocking condition of the Bluetooth Mesh network is reduced.
It can be seen that, the node device in the embodiment of the present application can set the message sending parameters according to the broadcast packet based on the broadcast packet sent by the acquisition control device, and is associated with the number of node devices in the bluetooth Mesh network based on the message sending parameters, so that the node device can dynamically and adaptively adjust the message sending parameters according to the determined number of node devices in the bluetooth Mesh network, thereby adapting to the network scale condition of the bluetooth Mesh network and realizing reasonable setting of the message sending parameters of the node devices.
In some embodiments, based on the control operation of the control device on the node device and the monitoring operation of the device state, the node device may send information according to the first message sending parameter, so that the control device can determine the number of node devices in the bluetooth Mesh network, thereby sending the second broadcast packet to the node device.
In an optional implementation in which the node device sets the second message transmission according to the second broadcast packet, the node device may set a second message transmission parameter according to the number of the node devices carried in the second broadcast packet, where the second message transmission parameter is set correspondingly by the node device. In another optional implementation, the node device may set the message sending parameter as a second message sending parameter carried in a second broadcast packet, where the second message sending parameter is set by the control device according to the determined number of the node devices.
In some further embodiments, the second messaging parameters may include at least a first type of parameter associated with a number of times the node device sent a message and a second type of parameter associated with a time of sending the message by the node device.
Optionally, a first-type parameter in the second message sending parameters is in a positive correlation with the number of node devices, when the number of node devices increases, the first-type parameter increases, and the increased first-type parameter is greater than a first-type parameter in the first message sending parameters; when the number of the node devices is reduced, the first type parameters are reduced, and the reduced first type parameters are smaller than the first type parameters in the first message sending parameters.
Optionally, a second type parameter in the second message sending parameters has a negative correlation with the number of the node devices; when the number of the node devices is increased, the first type of parameters are decreased, and the decreased second type of parameters are smaller than the second type of parameters in the first message sending parameters; when the number of the node devices is reduced, the first type of parameters are increased, and the increased second type of parameters are larger than the second type of parameters in the first message sending parameters.
In some embodiments, the node device sets a second message sending parameter according to the second broadcast packet, and further, after the node device acquires the broadcast packet sent by the control device again, the node device may send the message according to the second message sending parameter, and specifically, the node device may determine a random delay corresponding to a second type parameter in the second message sending parameter, so that in a broadcast period of the control device, if a random delay time corresponding to the node device is reached, the message is sent.
In some further embodiments, the random delay of the node device may be associated with the number of node devices based on the broadcast packet periodically broadcast by the control device acquired by the node device. As an optional implementation, if the number of the node devices is increased, the random delay determined by the node device for the second type of parameter in the second message sending parameters is smaller than the random delay determined by the second type of parameter in the first message sending parameters; as another optional implementation, if the number of the node devices is decreased, the random delay determined for the second type of parameter in the second message sending parameters is greater than the random delay determined for the second type of parameter in the first message sending parameters.
It should be noted that, the random delay of each node device in the broadcast period of the control device means that each node device randomly delays according to the broadcast period time of the control device on the premise that the number of node devices is satisfied, so as to avoid data collision of each node device and ensure that the actual transmission time of each node device is hashed in the broadcast period of the control device. For example, the broadcast period of the control device is 30 seconds, which totally controls 50 node devices, and the transmission time for the 50 node devices to transmit messages to the control device is randomly determined within 30 seconds (i.e., the 50 node devices randomly transmit messages to the control device within 30 seconds), thereby reducing the collision probability.
It can be understood that, in the bluetooth Mesh network, the number of the bluetooth Mesh gateways may be multiple, and when the node device belongs to the control range of multiple bluetooth Mesh gateways, the second message sending parameter corresponding to the node device may be set by the number of the node device determined by the bluetooth Mesh gateway that controls the maximum number of the node devices. Figure 3 illustrates another alternative example diagram of a bluetooth Mesh network.
As shown in fig. 3, the bluetooth Mesh network may include: bluetooth Mesh gateways G1 and G2, node devices N1, N2. Wherein, G1 covers 10 node devices, N1 to N10 respectively, G2 covers 92 node devices, N8 to N99 respectively, and node devices N8, N9, and N10 are simultaneously within the coverage range of two gateways of G1 and G2, then G1 and G2 both send broadcast packets to N8, N9, and N10, and N8, N9, and N10 can all obtain the broadcast packets. However, in the process of setting the message transmission parameters by N8, N9, and N10, if the number of node devices controlled in the coverage area based on G2 is greater than the number of node devices controlled in the coverage area based on G1, N8, N9, and N10 set the message transmission parameters according to the contents of the broadcast packet broadcast by G2.
