Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In order to solve the technical problem, an embodiment of the present invention provides a network distribution method. Fig. 1 is a flow chart of a network distribution method according to an embodiment of the present invention. As shown in fig. 1, the network distribution method at least includes steps S102 to S108:
step S102, receiving communication information sent by other equipment in the mesh network, wherein the communication information comprises network addresses and unique identification marks of the equipment;
step S104, judging whether the network address of the user is the same as the received network addresses of other devices;
step S106, if yes, calculating the unique identity of each device with the same network address according to a preset rule to obtain the ID value of each device;
and S108, comparing the ID value with the obtained ID values of other devices by using a comparison strategy, and determining whether to modify the network address of the device according to the comparison result.
According to the network distribution method, for any equipment in the mesh network, the communication information sent by other equipment in the mesh network can be received firstly. The communication information carries the network address and the unique identity of each other device. At this time, the device side acquires the network addresses and the unique identification information of other devices in the mesh network. Further, the acquired network address of each device is compared with the network address of the device itself, and whether the network address of the device itself is the same as the received network addresses of the other devices is judged. If so, calculating the unique identity of each device with the same network address according to a preset rule to obtain the ID value of each device. And then, comparing the self ID value with the obtained other equipment ID values by using a comparison strategy, and determining whether to modify the self network address according to the comparison result. Therefore, the network distribution method realizes the autonomous communication through the mutual interaction among the devices in the mesh network, does not need to relate to additional components, and can realize the synchronization of network addresses only through the mesh devices, thereby greatly shortening the network distribution time and reducing the network distribution time cost. And all the devices are communicated with each other, so that all the devices participate in the process of distribution network, the efficiency of distribution network is improved, and the error rate of uniformly distributing the network for all the devices by the additional components is reduced from the side. In addition, by the network distribution mode, even if the mesh equipment is abnormal after the network distribution, the uniqueness of the mesh equipment can be still ensured through transient network synchronization, and the compatibility of the equipment in the mesh network is improved.
The network distribution method of the embodiment is based on a mesh network, namely a wireless mesh network, which is a wireless multi-hop network, is a novel wireless mobile communication technology based on IP access, and is suitable for regional environment coverage and broadband high-speed wireless access. In practical application, the mesh network has the advantages of high broadband speed and high spectrum efficiency based on mutual cooperation and cooperation among a plurality of wireless access points distributed in a mesh manner, and has the outstanding characteristics of dynamic self-organization, self-configuration, self-maintenance and the like.
Fig. 2 is a schematic diagram of interaction among devices in a mesh network according to an embodiment of the present invention. As shown in fig. 2, there are A, B, C, D four devices in the mesh network, each of which may exist as a node of the mesh network. Of course, any multiple devices may also exist in the mesh network, for example, multiple devices may be added or reduced according to actual requirements on the basis of the current device, so as to form a new mesh network. This embodiment only exemplifies A, B, C, D four devices in fig. 2, and does not constitute a specific limitation to the number of devices in the mesh network of the present invention.
It should be further noted that, in this embodiment, as shown in fig. 2, connection lines are shown among the device A, B, the device A, C, the device A, D, the device B, C, and the device B, D, and no connection line exists among the devices C, D, which indicates that the devices showing the connection lines may directly communicate with each other, and the device C, D may not implement direct communication due to too far distance or other possible reasons, and this embodiment may implement indirect communication between the devices C, D in a form that the other device nodes receive and forward communication information, and serve as relay points. Of course, if the device C, D satisfies the condition for direct communication, the direct communication may be adopted, and fig. 2 is only an example and does not constitute a specific limitation on the communication method between the devices. The connection lines shown in fig. 2 also represent only a direct communication method between the devices, and do not limit a specific communication path or other communication means between the devices.
Further, with the continuous development of wireless mesh networks, more and more devices are in the mesh networks. According to the method of the present invention, when each device in the mesh network is connected to the network, step S102 may be executed for any device in the mesh network to receive the communication information sent by other devices in the mesh network. The communication information may include a network address and a unique identifier of each device. Specifically, in this embodiment, a specific time window (for example, after power-on) of each device in the mesh network may periodically send a heartbeat packet to other devices in a specific range around, so that the devices in the mesh network perceive each other through the heartbeat packet. Of course, if the coverage area of the mesh network is large, when the heartbeat packet sent by a certain device node cannot be directly transmitted to all device nodes in the mesh network, part of the device nodes in the mesh network may also be used as relay points, and the heartbeat packet is forwarded to a device node in a farther range through the part of the device nodes until all the device nodes in the mesh network can sense other device nodes except the device node.
In this embodiment, when each device in the mesh network is configured, the network address and the unique identity of each device are carried in the heartbeat packet based on the heartbeat packet. By the method, each device in the mesh network can acquire the communication information of other devices within a short time after the device is powered on. Further, step S104 is executed to determine whether the own network address is the same as the received network address of the other device. Whether the network addresses of the devices in the mesh network conflict can be determined through the judging step. If so, further processing is carried out on each device with the network address conflict, so that the network addresses of all the devices in the mesh network are unique. If not, the network addresses of the devices in the mesh network are not conflicted, other operations are not required to be executed on the devices, and the process is directly finished.
Specifically, after step S104 is executed, if the network address of the device is the same as the received network address of the other device, step S106 is further executed, and the unique ID of each device with the same network address is calculated according to the preset rule, so as to obtain the ID value of each device. In this embodiment, a hash algorithm may be used to calculate the unique identifiers of the devices with the same network address to obtain hash values of the devices, and then the hash values of the devices are used as ID values of the devices. In addition, in this embodiment, the unique identifier of each device may be calculated by using any other feasible algorithm as a preset rule, and the hash algorithm is only an example and does not constitute a specific limitation on the preset rule in this embodiment.
After the ID values of the devices with the same network address in the mesh network are obtained according to the above operation steps, step S108 may be further performed, the ID value of the device itself is compared with the obtained ID values of the other devices by using a comparison policy, and whether to modify the network address of the device itself is determined according to the comparison result. Specifically, the self ID value may be first compared with the obtained ID values of the other devices one by one according to the size of the ID value, so as to obtain a comparison result.
After the comparison result is obtained, whether to modify the network address of the mobile terminal according to the comparison result can be determined. In this embodiment, the comparison policy may be set in a user-defined manner according to actual requirements of the user, for example, the comparison policy may be set in advance such that the device with the larger ID value of the two devices with the conflict modifies the comparison policy, the device with the smaller ID value retains the original network address, that is, it is determined that the device with the conflict is present, and it is further determined that the network address of the device with the smaller ID value is modified if the ID value of the device with the smaller ID value is greater than the ID values of the other devices, and otherwise, the original network address is retained. In this case, when the ID value of the device itself is compared with the ID values of the other devices according to the comparison policy, if the ID value of the device itself is smaller than the ID values of the other devices, it is not necessary to perform other operations on the device, and if the ID value of the device itself is larger than the ID values of the other devices, it is necessary to further modify the network address of the device. In addition, the comparison policy may be preset such that the device with a smaller ID value of the two conflicting devices modifies the comparison policy, the device with a larger ID value retains the original network address, that is, determines that the conflicting device exists, and further determines to modify the network address if the ID value of the device is smaller than the ID values of the other devices, otherwise, retains the original network address. In this case, when the ID value of the device itself is compared with the ID values of the other devices according to the comparison policy, if the ID value of the device itself is larger than the ID values of the other devices, it is not necessary to perform other operations on the device, and if the ID value of the device itself is smaller than the ID values of the other devices, it is necessary to further modify the network address of the device.
In the embodiment, only by comparing and distinguishing the ID values of the devices with the same network address, selective modification is performed, so that the devices with the same network address originally have different network addresses. It should be noted that the comparison policy in this embodiment is only an example, and the network distribution method of the present invention may also perform operation processing on the ID values of the devices with the same network address through other various measures, which is not specifically limited in this embodiment.
In addition, in this embodiment, when modifying the network address of the corresponding device in the mesh network, the network address can be modified uniformly by an additional device, or can be modified autonomously by the device. In this embodiment, the network address of the device may be modified, preferably by means of an autonomous modification of the device. When the network address of the other equipment in the mesh network is modified, the equipment can be combined with the received network address of the other equipment in the mesh network to modify autonomously, so that the modified network address does not conflict with the network addresses of the other equipment in the mesh network, and the network addresses of the equipment in the mesh network are unique.
Therefore, the network distribution method realizes the autonomous communication through the mutual interaction among the devices in the mesh network, does not need to relate to additional components, and can realize the synchronization of network addresses only through the mesh devices, thereby greatly shortening the network distribution time and reducing the network distribution time cost. And all the devices are communicated with each other, so that all the devices participate in the process of distribution network, the efficiency of distribution network is improved, and the error rate of uniformly distributing the network for all the devices by the additional components is reduced from the side. In addition, through the network distribution mode, even if the equipment is abnormal after the network is distributed, the uniqueness of each equipment can be still ensured through transient network synchronization, and the compatibility of the equipment in the mesh network is improved.
The network distribution method of the present invention is specifically described in several specific embodiments below.
Example one
The mesh network of the invention can be composed of a plurality of wireless nodes, and with the development of the standard Bluetooth mesh protocol, more and more Bluetooth nodes in the mesh network become common. In this embodiment, a network distribution method according to the present invention is described in detail by taking a bluetooth device as a basis and taking two bluetooth devices (bluetooth device A, B) as an example.
Fig. 3 is a flowchart of a method for a bluetooth device a and a bluetooth device B to participate in a network distribution according to an embodiment of the present invention. As shown in fig. 3, in this embodiment, a bluetooth device a is mainly used for introduction (a bluetooth device B is the same as a method for the bluetooth device a to participate in a distribution network).
In this embodiment, step S302 is first executed, where the bluetooth device a receives a heartbeat packet sent by the bluetooth device B, and the heartbeat packet carries a network address and a unique identity of the bluetooth device B. In this step, the bluetooth device B may also receive the heartbeat packet sent by the bluetooth device a, and the two perform communication interaction through the heartbeat packet of each other. The present embodiment will be described mainly with respect to a bluetooth device a.
Further, step S304 is executed to determine whether the network address of the bluetooth device a itself is the same as the received network address of the bluetooth device B. If not, the network addresses of the Bluetooth device A and the Bluetooth device B are not conflicted, the network addresses do not need to be modified, and the judgment process is finished. If the network addresses of the bluetooth device a and the bluetooth device B are the same, step S306 is executed to further determine whether the network address of the bluetooth device a and the network address of the bluetooth device B need to be modified.
It should be noted that, in this embodiment, the network distribution method of the present invention is specifically described only by taking the bluetooth device a and the bluetooth device B as examples, and in this embodiment, a plurality of other bluetooth devices may be further added on the basis of the bluetooth device A, B, and the network distribution mode of the present embodiment is the same as the network distribution mode of the present embodiment, and is not described herein again.
Example two
The present embodiment is based on the first embodiment, and is still described mainly by the bluetooth device a. When the network addresses of the bluetooth device a and the bluetooth device B conflict, it needs to be further determined whether the network address of the bluetooth device a and the network address of the bluetooth device B need to be modified.
Specifically, fig. 4 is a flowchart of a method for determining whether the bluetooth device a needs to modify its own network address according to an embodiment of the present invention. As shown in fig. 4, step S402 is first executed to obtain the unique id information of the bluetooth device B. In this step, the unique id may be carried in a heartbeat packet sent by the bluetooth device B, and after the bluetooth device a receives the heartbeat packet, the unique id information of the bluetooth device B may be obtained.
Further, step S404 is executed to calculate the unique identifiers of the bluetooth device a and the bluetooth device B according to the preset rule, so as to obtain the ID value of the bluetooth device A, B. In this step, the unique ID of the bluetooth device A, B may be processed by using a hash algorithm, and a corresponding hash value is obtained by calculation, and the hash value of the bluetooth device A, B is further used as the ID value of each of the unique IDs. Of course, the unique identity of the bluetooth device A, B may also be calculated by other algorithms, which is not specifically limited in this embodiment.
Subsequently, in the present embodiment, the comparison policy may be continuously set, and the ID value of the bluetooth device A, B may be determined according to the comparison policy. The comparison policy may be customized according to a user selection, for example, in this embodiment, it may be set that when the ID value of the comparison policy is larger than the ID values of other devices, the network address of the comparison policy is modified, and otherwise, the original network address is retained. Further, step S406 is executed to determine whether the ID value of the bluetooth device a itself is larger than the ID value of the bluetooth device B, if so, step S408 is executed, and if not, step S410 is executed. Of course, this embodiment may also set other comparison strategies to compare the ID values of the bluetooth devices A, B, which is not specifically limited in this embodiment. The present embodiment is mainly described with the bluetooth device a, and it should be understood that the bluetooth device B also performs the determination of the ID value at the same time, except that the determination result of the bluetooth device B is opposite to that of the bluetooth device a, that is, when the bluetooth device a subsequently performs step S408, the bluetooth device B subsequently performs step S410.
Step S408, the network address of the user is modified. In this step, the network address of the bluetooth device a may be modified by an additional component, and the network address of the bluetooth device a itself may also be modified autonomously by the bluetooth device a.
Step S410, the original network address is retained.
In conclusion, the invention realizes the autonomous communication through the mutual interaction among the devices in the mesh network, does not need to relate to additional components, and can realize the synchronization of network addresses only through the mesh devices, thereby greatly shortening the time of the network distribution and reducing the time cost of the network distribution. And all the devices are communicated with each other, so that all the devices participate in the process of distribution network, the efficiency of distribution network is improved, and the error rate of uniformly distributing the network for all the devices by the additional components is reduced from the side. In addition, through the network distribution mode, even if the equipment is abnormal after the network is distributed, the uniqueness of each equipment can be still ensured through transient network synchronization, and the compatibility of the equipment in the mesh network is improved.
