Description
Technical Field
The invention relates to the field of intelligent home furnishing, in particular to a B L E Mesh node state synchronization method.
Background
At present, more and more intelligent lamp control entries based on the B L E MESH are provided, such as mobile phone APP control, Alexa voice control, sensor control and the like, so that the problem of unsynchronized lamp states among different devices is more and more prominent, for example, when a lamp is changed from a light-off state to a light-on state, a cloud terminal needs a certain time to synchronize information of different devices or the synchronization fails.
In order to solve the above problems, there are two conventional methods (1) in the B L E Mesh network, a special device (e.g., a gateway) periodically and alternately reads the state information of each node, and the method has low synchronization efficiency and takes a long time, (2) when the node state sends a change, the node actively reports the state information to the cloud.
Disclosure of Invention
In order to solve the above problems, the present invention provides a method for synchronizing the states of B L E Mesh nodes, the specific scheme is as follows:
a method for synchronizing the state of a B L E Mesh node comprises the following steps:
s1, when the distributor distributes the network to the B L E MESH device, the distributor distributes a different short address to the node corresponding to each device in the network according to the UUID of each device in the network;
s2: the access port starts to read the broadcast information of the state information of each node in the network at a rated time interval;
s3: after receiving the broadcast information, the node reports the state information corresponding to the node to the access port within a rated reporting time period;
s4: the access port judges whether the state information of all the nodes is received, if so, the access port enters S6; otherwise, the distribution network person waits for the rated time interval TnThen, recording the short address of the node corresponding to the unreceived state information and the synchronization failure times of the node, and entering S5;
s5: judging whether the synchronization failure times of the node are larger than a time threshold value, if so, setting the state of the node as an offline state, and entering S6; otherwise, returning to S2;
s6: and the access port updates the state information of all the nodes into the storage addresses of all the access ports corresponding to the network.
Further, a nominal time interval TnThe calculation formula of (2) is as follows: t isn＝n0T, wherein n0For the total number of nodes contained in the network, T is the time required for each node to reply to the broadcast message.
Further, the nominal reporting time period t of the Nth nodenSatisfies the following conditions:
(N-1)*T<tn<N*T
where T is the time required for each node to reply to the broadcast message.
By adopting the technical scheme, the state information of all the nodes in the network can be quickly synchronized, the accuracy is high, the method is not limited by the number of the network nodes, and the real-time performance is high.

In this embodiment, T is setn＝n0T; wherein n is0For the total number of nodes contained in the network, T is the time required for each node to reply to the broadcast message.
S3: after receiving the broadcast information, the node reports the state information corresponding to the node to the access port within a rated reporting time period.
In this embodiment, a nominal reporting time period t of the nth node is setnComprises the following steps:
(N-1)*T<tn<N*T
s4: the access port judges whether the state information of all the nodes is received, if so, the access port enters S6; otherwise, the distribution network person waits for the rated time interval TnThen, the short address of the node corresponding to the status information that has not been received and the number of times of synchronization failures of the node are recorded, and the process proceeds to S5.
Waiting for a nominal time interval TnIn order to ensure that all nodes report.
S5: judging whether the synchronization failure times of the node are larger than a time threshold value, if so, setting the state of the node as an offline state, and entering S6; otherwise, return to S2.
The number threshold can be set by the skilled person empirically, in this example set to 3.
