The data transmission method provided by the embodiment of the present application may be applied to a data transmission system as shown in fig. 4, where the network with a structure suitable for the diagram may be a zigbee network or other networks such as Thread.
The data transmission system in the figure includes a node device 11, a parent node device 12, a forwarding and forwarding device 13, and a target network management node 14.
The node device 11 may be any device having a communication function, such as a Personal Computer (PC), a mobile phone, a tablet Computer, and a wearable electronic device, and is intended to emphasize a network node structure and an individual.
The parent node device 12 is a direct contact of the node device 11 in the network, and may be a full function device (FFD device), a forwarding device (coordinator), a routing device (Router device), or the like, or may be a general node device 11.
The parent node device 12 is not necessary, that is, a certain node device 11 may not have a corresponding parent node device 12 in the network; second, parent node device 12 may translate with forwarding devices 13, i.e., a forwarding device 13 may be directly a parent node of node device 11.
The forwarding device 13 may be a device with a data forwarding function, such as a router, and certainly, a device such as a coordinator and a gateway may also serve as the forwarding device 13.
The target network management node 14 is a destination of the data transmitted by the node apparatus 11. The embodiments of the present application do not limit this. Illustratively, in fig. 3, the node device 11 is an End device, the parent node device 12 is a Router1, the forwarding device 13 is a Router2, a Router3, a Router4, or a Router5, and the target network management node 14 is a Leader, and of course, the Leader may also serve as the forwarding device 13.
Referring to fig. 5, a data transmission method provided for an embodiment of the present application may be applied to the node device shown in fig. 4, where the data transmission method includes but is not limited to S101, and is specifically described as follows:
s101, judging whether the network state of the user self meets the requirement of data generation.
Here, the network state may refer to network quality. The condition that the data can be broadcasted by the current device may be satisfied by the data transmission-compliant member, and the condition may be that the network quality cannot satisfy normal transmission of the data signal, for example, the bandwidth of the network channel is insufficient or the load is too large, the hardware of the network device fails, the data transmission rate is lower than a set threshold, and the decoding rate of the network device after receiving the data packet is too small; but also in the case of node device offline, etc., and is not limited herein. The determining whether the network state of the node device satisfies the data generation condition may be determining whether the network state of the node device satisfies the data generation condition.
S102, if the current network state meets the data generation condition, broadcasting the data to be transmitted which needs to be uploaded so that forwarding equipment in at least one slave network or an adjacent network can carry out generation uploading on the data to be transmitted; the data to be transmitted carries additional information, wherein the additional information at least comprises a physical address of the device.
In one embodiment, the broadcast is preferably in a "one-to-all" communication mode, i.e., global broadcast; for example, if 27 channels are provided, broadcasting is performed in the 27 channels, so that all electronic devices with receiving functions in the slave network or the neighboring network can receive data carrying specified identification information sent by the node device. The forwarding device may be a gateway device or a coordinator device, etc. The slave network is a network where the node device is located, and the adjacent network is another network close to the network where the node device is located. The additional information at least includes the physical address of the node device itself, and the physical address may be a mac address, a short address, or a 64-bit unique extension address of the node device. Before sending the data to be transmitted, the node equipment detects that the current network state meets data generation conditions, and if the current network state meets the data generation conditions, the node equipment broadcasts the data to be transmitted, which needs to be uploaded.
According to the data transmission method, when the node equipment cannot perform data interaction with the father node equipment in the network, external transmission of specific data of the node equipment can be achieved without the node equipment accessing the network again, and the specific data can be transmitted to a destination in real time.
In some embodiments, the broadcast is in the form of a global broadcast.
In some embodiments, the data transmission condition is that the device itself is in an offline state or the data uploading rate is less than a preset value.
Here, the offline state is an offline state of the node apparatus. The preset value may be a threshold value stored in the node device manually in advance or through an upper network indication. The data transmission condition that the device is in an off-line state or the data uploading rate is less than a preset value may be: the node device judges whether the node device is in an off-line state or not at present or whether the data uploading rate of the node device and a father node device is smaller than a preset value or not. For example, when the node device transmits data to the parent node device, the node device counts the data transmission amount in unit time, and if the data transmission rate is determined to be zero, the node device determines that the node device is in the off-line state; if the data transmission rate is smaller than the preset value, determining that the data transmission rate of the father node equipment is smaller than the preset value; and then determining that the network state of the node equipment meets the data transmission condition. In addition, after the node device determines that the node device is in an offline state or the data transmission rate with the parent node device is smaller than a preset value, the duration of the offline state or the data transmission rate with the data transmission rate smaller than the preset value is recorded, and if the duration reaches a preset time threshold value, for example, 3S, it is determined that the data transmission path with the parent node device does not meet preset conditions.
The node device in the embodiment of the application is used as a basis for judging whether a data transmission path between the node device and a parent node device meets a preset condition according to whether the node device is in an offline state or not at present or according to whether the data transmission rate between the node device and the parent node device is smaller than a preset value or not. Therefore, the problem of time delay of the node equipment during data transmission can be solved, and the data to be transmitted can be broadcasted in time under the condition that the network condition does not meet the preset condition.
In some embodiments, before the broadcasting of the data to be transmitted carrying the specified identification information, the method further comprises: and encrypting the data to be transmitted by adopting an installation code.
Here, install code is a data encryption method. And encrypting the data to be transmitted by adopting the installation code, namely encrypting the data to be transmitted by adopting the install code by the node equipment.
The node equipment in the embodiment encrypts the data to be transmitted by adopting the installation code, so that the node equipment and other equipment in the network cannot be threatened even if the data to be transmitted is received by illegal equipment, and the safety of the data to be transmitted in the transmission process is enhanced.
In some embodiments, after the step of broadcasting the data to be transmitted, the method further includes: monitoring the feedback message of the forwarding device, and if the feedback message of the forwarding device indicates that the data to be transmitted needs to be retransmitted, broadcasting the data to be transmitted again.
Here, the feedback message refers to a response based on the additional information carried by the broadcast of the node device. The feedback message may include status information indicating whether the report of the data to be transmitted is successful, such as an ACK acknowledgement message or a NACK negative acknowledgement. And if the feedback information indicates that the data to be transmitted is not reported successfully and needs to be retransmitted, the node equipment broadcasts the data to be transmitted with additional information again.
In the embodiment of the application, the node equipment broadcasts the data to be transmitted with additional information again according to the received feedback information returned by the forwarding equipment and according to the state information which is contained in the feedback information and used for indicating that the data to be transmitted needs to be retransmitted; therefore, the problem of data loss of the node equipment can be solved, and the effectiveness of broadcasting the data to be transmitted is improved.
In some embodiments, before the step of broadcasting the data to be transmitted that needs to be uploaded, the method further includes: and suspending the network re-accessing action of the slave network until the broadcasting of the data to be transmitted is finished.
Here, the suspending the re-network entry behavior to the slave network may refer to suspending the re-network entry behavior to the previous network by the node device, so as to avoid radio frequency interference caused by performing re-network entry and broadcast simultaneously.
In the embodiment of the application, the node equipment suspends the network re-accessing behavior to the slave network until the broadcasting of the data to be transmitted is finished, so that the node equipment can also send the data to be transmitted without executing network connection, the problem of data delayed transmission is solved, and the efficiency of data transmission is improved.
In some embodiments, the additional information further includes a preset first identifier, where the first identifier is used to instruct the forwarding device to unconditionally upload the data to be transmitted.
Here, the first identifier may be preset field information for characterizing that the additional information is unconditionally uploaded by the receiving device.
Illustratively, the first identification information is "aqara," and is embedded in a packet header of the data to be transmitted, the forwarding device obtains an aqara field from the decoded packet header, and directly performs generation uploading on the data to be transmitted, regardless of whether a white list of the forwarding device includes a physical address carried by the data to be transmitted.
In the embodiment of the application, the additional information is further limited, so that the identification degree of the data to be transmitted is improved, and the data to be transmitted is further ensured to be uploaded to a destination in time.
Referring to fig. 6, an embodiment of the present application further provides a data transmission method applied to a forwarding device, where the method includes:
s201, receiving data to be transmitted, which is broadcasted by node devices in at least one slave network or an adjacent network.
With continued reference to fig. 3, the forwarding device may be one of Router2-5 or Leader. The receiving of the to-be-transmitted data broadcast by the node device in the at least one slave network or the adjacent network may refer to the forwarding device receiving the to-be-transmitted data broadcast by the node device in the at least one slave network or the adjacent network.
S202, analyzing the additional information carried by the data to be transmitted.
Here, the forwarding device parses the additional information carried by the data to be transmitted. Wherein the additional information comprises at least a physical address of the device itself.
S203, if the additional information meets the preset generation component, the data to be transmitted is uploaded in a generation mode.
Here, the generation member may refer to a criterion for judging whether data can be generated. The additional information satisfying the preset generation condition may mean that the physical address of the node device included in the additional information satisfies the preset generation condition. For example, referring to fig. 3, route2 receives data to be transmitted, which carries additional information of a node device, determines whether the node device is in a preset white list according to the additional information of the node device, and if the node device is in the preset white list, determines that the received data to be transmitted is transfer data meeting a preset transfer rule, and transfers the data to be transmitted to a Leader. Otherwise, route2 discards the received transmission data.
The white list may be distributed by an upper layer, which may be, for example, a leader, a cloud, or a core network. In an embodiment, a user configures a white list of Route2 through an APP, and after the APP reports the white list to a cloud, the cloud issues the white list to the corresponding Route2.
According to the data transmission method, the forwarding device determines whether the data to be transmitted is forwarded or not according to the additional information carried by the received data to be transmitted, so that the problem that the data to be transmitted cannot be transmitted to a destination when the node device does not meet the preset network condition can be solved, and the data to be transmitted of the node device can be smoothly transmitted to the destination.
In some embodiments, before the step of receiving data to be transmitted broadcast by node devices in at least one slave network or adjacent network, the method further includes: and receiving a configuration list issued by a superior network, and storing the physical address of the node equipment bound with the node equipment in the configuration list to form a white list.
Here, the upper network may be a target management node or a cloud server. The configuration list refers to a node equipment list that the data to be transmitted can be received by a target management node or a cloud server. The white list refers to a list of node devices whose data to be transmitted have a forwarding device sending qualification. The receiving a configuration list issued by a superior network, and storing the physical address of the node device bound to the configuration list to form a white list may refer to: the forwarding device receives a configuration list issued by a target management node or a cloud server, and binds and stores the physical address of the node device bound with the forwarding device in the configuration list to form a white list. For example, after receiving data to be transmitted, which is sent by node equipment and carries additional information, route2 compares an MAC address in the additional information with white list data to determine whether the node equipment is in a white list, and if the additional information indicates that the node equipment is a preset binding storage device, determines that the data to be transmitted is data that conforms to a preset generation rule.
In the embodiment of the application, the forwarding device receives a configuration list issued by a superior network, and stores the physical address of the node device bound with the forwarding device in the configuration list to form a white list. Therefore, the forwarding equipment can identify the data to be transmitted sent by the node equipment meeting the transmission generation condition, so as to ensure that the data to be transmitted is forwarded to the destination in time.
In some embodiments, the additional information comprises at least a physical address of the node device. In the embodiment of the application, the additional information is further limited, so that the identification degree of the data to be transmitted is improved, and the data to be transmitted is further ensured to be uploaded to a destination in time.
In some embodiments, the satisfaction of the generation condition is that the physical address of the node device is included in a preset white list, and/or that the device itself is an optimal forwarding device chosen according to a preset election rule.
Here, the preset election rule is a rule for determining a forwarding device most suitable for transmitting data to be transmitted among the plurality of forwarding devices. The optimal forwarding device that the device itself elects according to the preset election rule may be the optimal forwarding device that the forwarding device elects according to the preset election rule. For example, the forwarding device receives an optimal forwarding device that is decided by a third party (upper layer) according to a preset election rule, or an optimal forwarding device that is decided by the forwarding device itself from among the plurality of forwarding devices according to a preset election rule.
In the embodiment of the application, by determining that the physical address of the node device is contained in the preset white list and/or determining that the forwarding device is the optimal forwarding device chosen according to the preset election rule, the stability and timeliness of transmitting the data to be transmitted to the destination are effectively ensured.
In some embodiments, the preset election rules include a first rule that: reporting the self network transmission information to an upper layer so that the upper layer compares the information with the transmission information of other forwarding devices to obtain an optimal forwarding device; and monitoring the optimal forwarding equipment decided by the upper layer.
Here, the upper layer may refer to a target network management node or a cloud server. The reporting of the network transmission information to the upper layer so that the upper layer compares the information with transmission information of other forwarding devices to obtain an optimal forwarding device may refer to: the forwarding device reports the network transmission information to a target network management node or a cloud server, so that the target network management node or the cloud server compares the network transmission information with transmission information of other forwarding devices, and an optimal forwarding device is obtained. Therefore, the stability and timeliness of transmitting the data to be transmitted to the destination are effectively guaranteed.
In some embodiments, the preset election rule includes a second rule that: broadcasting the network transmission information of the self, and monitoring the network transmission information broadcast by other forwarding equipment at the same time; judging whether the network transmission capability of the forwarding equipment is superior to that of other forwarding equipment or not according to the network transmission information broadcasted by other forwarding equipment; if yes, continuously broadcasting; if not, stopping broadcasting; and until a forwarding device for broadcasting the network transmission information of the forwarding device is remained, wherein the forwarding device is the optimal forwarding device.
Here, the network transmission information of the forwarding device is broadcasted, and the network transmission information broadcasted by other forwarding devices at the same time is monitored; judging whether the self network transmission capability is superior to the other forwarding devices according to the network transmission information broadcasted by the other forwarding devices; if yes, continuously broadcasting; if not, stopping broadcasting; until there remains a forwarding device that broadcasts network transmission information of itself, the forwarding device, which is an optimal forwarding device, may specifically be: the method comprises the steps that first signal quality information between a forwarding device broadcast and a destination is obtained, second signal quality information between the forwarding device broadcast and the destination broadcast by other forwarding devices in a network is obtained, if the second signal quality information broadcast by other devices is better than the first signal quality information broadcast by the forwarding device, the device stops broadcasting the first signal quality information and considers that the device is not the optimal transmission device and does not transmit data to be transmitted (give a self-silence instruction), the process is also executed on other forwarding devices, and finally, only one forwarding device with the optimal signal quality information continuously broadcasts the signal quality information of the device, and at the moment, the device finds that no other comparable forwarding devices exist, the device is considered as the optimal forwarding device and processes the data to be forwarded.
The signal quality information refers to comprehensive evaluation information of each influencing factor when the network transmits data, and comprises data transmission rate, stability in the data transmission process, decoding rate after data reception and the like. For example, please continue referring to fig. 3, route2 determines first signal quality information between itself and Leader or an upper layer, and obtains second signal quality information between Route1 and Leader or the upper layer, second signal quality information between Route3 and Leader or the upper layer, second signal quality information between Route4 and Leader or the upper layer, and second signal quality information between Route5 and Leader or the upper layer, and determines whether the first signal quality information is better than the second signal quality information according to a comparison between the first signal quality information and a plurality of second signal quality information,
in the embodiment of the application, the forwarding equipment broadcasts the network transmission information of the forwarding equipment and monitors the network transmission information broadcast by other forwarding equipment at the same time; and judging whether the network transmission capability of the forwarding equipment is superior to that of the other forwarding equipment according to the network transmission information broadcasted by the other forwarding equipment so as to determine whether the forwarding equipment can transmit data for generation. Therefore, the forwarding equipment can identify the data to be transmitted sent by the node equipment, so as to ensure that the data to be transmitted is forwarded to the target network management node in time.
In order to enable a more systematic understanding of the data transmission method provided in the embodiment of the present application, the following description is made by using a specific example, please refer to fig. 7, which specifically includes:
s301, the node equipment judges whether the network state of the node equipment meets the requirement of a data generation component or not; if yes, go to step S302; if not, ending.
