However, the high-speed power line carrier communication still has a blind acquisition point and a rate bottleneck. For example, due to excessive line attenuation, there are some application scenarios where data cannot be copied or communication is unstable.

In order to solve the problems of blind spots and instability of the existing single communication mode, multi-mode communication combining multiple communication modes such as high-speed power line carrier, micropower wireless, narrowband power line carrier and Bluetooth is gradually adopted, and on one hand, the blind spot problem is solved, and on the other hand, the communication speed and the communication reliability can be improved through the multi-mode communication. However, the existing multimode communication methods mainly include the following two methods: (1) the communication is carried out in a relay mode, namely, one mode is preferably adopted for communication generally, and when the communication in the mode is unsuccessful, the communication is switched to another mode to attempt communication; (2) the point-to-point intercommunication is realized by simply adopting the combination of a plurality of communication modes, but serious mutual interference exists among the plurality of modes, so that the communication quality is influenced.

None of the above conventional communication methods efficiently utilizes a plurality of communication modes to improve communication quality.

Detailed Description

The following describes in detail embodiments of the present invention with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are given by way of illustration and explanation only, not limitation.

Before describing various embodiments of the present invention, a brief description of the nodes involved in the present invention will be provided.

The root node may be a zone convergence terminal (e.g., a concentrator CCO). The network access node, the node to be accessed to the network, the communication starting node, the communication target node, the first node and the second node can be all acquisition terminals (namely multimode communication equipment), and the acquisition terminals can communicate with the root node. Specifically, the acquisition terminal can be an electric energy meter, a branch switch, a distribution network device, a sensor and the like which are provided with a multi-mode communication module.

Fig. 1 is a flowchart of a networking method of a multimode communication device according to an embodiment of the present invention. As shown in fig. 1, the networking method may include the following steps S101-S103.

Step S101, determining response information of available communication modes between a network access node and a node to be accessed through a networking discovery process.

Wherein the available communication modes include communication modes in a plurality of sets of communication modes, and the communication modes in each set of communication modes are incompatible with each other and the communication modes in different sets of communication modes are compatible with each other.

In particular, the available communication modes between the network entry node and the node to be networked may comprise a plurality of communication modes. For example, the plurality of communication modes may include a high-speed power line carrier communication mode, a high-speed micro-power wireless communication mode (OFDM), a low-speed micro-power wireless communication mode (GFSK), a narrowband carrier communication mode, Bluetooth (BLE), and the like. In addition, the plurality of communication modes may also include different frequency bands of the same communication mode, for example, frequency band 0, frequency band 1, frequency band 2, and frequency band 3 of high speed power line carrier communication; or a high-speed micro-power wireless communication mode (OFDM) and a low-speed micro-power wireless communication mode (GFSK), etc.

In the present embodiment, in order to maximally utilize a plurality of mode resources, the plurality of communication modes may be grouped to classify modes in which mutual interference exists (for example, collision and interference exist between different frequency bands of high-speed power line carrier communication, or collision and interference exist between high-speed micro-power wireless and low-speed micro-power wireless) into the same mode set. Thus, the available communication modes may be divided into sets R1-Rm: r1 ═ M ₁₁ ，M ₁₂ ，……M _1i }，R2＝{M ₂₁ ，M ₂₂ ，……M _2j }，Rm＝{M ₃₁ ，M ₃₂ ，……M _3k }. By the mode of grouping the multiple modes, the multiple modes can be reasonably distributed in time, so that the multiple modes are fully utilized for communication, and the communication quality is improved.

The R1 can be a set of high-speed power line carrier communication modes (which can specifically include M ₁₁ Frequency bands 0, M ₁₂ Frequency band 1, M ₁₃ Frequency band 2, M ₁₄ -band 3); r2 is a set of narrowband carrier communication modes (which may include M) ₂₁ -narrowband carrier communication mode); r3 is a micro-power wireless communication mode set (which may specifically include M ₃₁ High speed micropower wireless communication mode, M ₃₂ Low speed micropower wireless communication mode, etc.). Each of the above modesWithin the set, different communication modes are incompatible with each other (i.e., only one mode can be in a transmitting or receiving state at a time), for example, frequency bands 0-3 of high speed power line carrier communication in R1, while only one frequency band can be transmitting or receiving (i.e., communicating). While communication modes in different sets of communication modes are compatible with each other (i.e., do not interact with each other between different sets), e.g., M in R1 may be used simultaneously ₁₁ M in frequency band 0, R2 ₂₁ Narrow band carrier communication mode with M in R3 ₃₁ High speed micro-power wireless communication mode for transmission or reception (i.e. communication).

By grouping the communication modes with conflicts and interferences, the interferences and conflicts in the communication process are avoided, and compatible communication of various communication modes such as narrow-band power line carriers, high-speed radios, low-speed radios and the like can be realized.

The node to be networked may be a node of a next layer of the network access node. For example, when the network access node is a layer 1 node, the node to be networked is a layer 2 node.

Wherein the response information may include: and the address of the node to be accessed to the network and the characteristic parameter for representing the channel quality of the communication mode. For example, the characteristic parameter may be a signal-to-noise ratio or a signal attenuation amount.

In various embodiments described below, the transceiver units (e.g., mode M) in various nodes (i.e., acquisition terminals) ₁₁ -M _3k Transceiver unit) may employ a common clock system (as shown in fig. 2A) or no common clock system (as shown in fig. 2B). The common clock system outputs a clock signal from a clock source to be distributed to the transceiving units so that each transceiving unit can synchronize through synchronous counting; the unshared clock system can ensure clock synchronization among the modes inside the acquisition terminal through an internal synchronization mechanism (such as a synchronization pulse): each transceiver unit has its own independent clock source, represented by mode M ₁₁ The transceiver unit outputs a synchronization pulse, M ₁₂ -M _3k The transceiver unit calibrates its clock source according to the interval of the synchronization pulse, as shown in fig. 2B. Of course, a setting may be made for each set of R1-RmA separate clock source, as shown in fig. 2C.

For step S101, the determining answer information about available communication modes between the network entry node and the node to be networked may include: broadcasting, by the network access node, a networking beacon frame in the communication mode of each communication mode set in sequence; sequentially switching one communication mode in each communication mode set by the node to be networked according to a first preset period so as to execute the receiving operation of the networking beacon frame; and determining, by the network access node, a communication mode in each communication mode set in which the networking beacon frame is received as a specific communication mode in the available communication modes, and sending response information about the specific communication mode to the network access node. That is, the available communication modes between the network access node and the node to be networked are composed of specific communication modes in each communication mode set.

Wherein the networking beacon frame may include hierarchical information of the network entry node. It should be noted that, in the following networking discovery phase, when a network access node performs networking discovery, a node at the same level or a node at a previous level of the network access node does not respond.

The first preset period may be greater than a period in which the network access node broadcasts the networking beacon frame in each of the communication mode sets.

The networking discovery phase mainly comprises the following processes executed by the network access node and the node to be accessed.

Taking the R1 set as an example, the network node (corresponding to the master node) uses the mode M in the R1 set ₁₁ -M _1i The networking beacon frame is broadcast in turn as shown in fig. 3. The beacon frame may carry the hierarchical information of the node to be networked. After each mode finishes sending the broadcast networking beacon frame, a time window for waiting for receiving the response of the nodes to be accessed to the network (equivalent to slave nodes) of the information can be reserved.

In parallel, the network entry node selects from the pattern M in the set of R2 ₂₁ -M _2j Broadcasting the networking beacon frames in sequence, wherein the beacon frames can also carry the hierarchical information of the nodes to be networked. And after each mode sends the broadcast networking beacon frame, a time window waiting for receiving the response of the network access node of the information can be reserved. By analogy, R1, R2, Rm are each independently broadcast in intra-set communication mode.

And the node to be networked (i.e. the node on the next layer of the network access node broadcasting the networking beacon frame) opens independent receiving channels in each set of R1, R2 and Rm to perform broadcast reception.

Taking the R1 set as an example, the to-be-networked node sequentially switches the modes in the R1 set at a first preset period. As shown in fig. 3, when the node 1 in the node to be networked is in a certain mode (e.g., mode M) ₁₁ ) Upon receipt of the networking beacon frame, a Carrier Sense Multiple Access (CSMA) response is immediately made, which may include the address of node 1 and the mode (e.g., mode M) ₁₁ ) The signal attenuation amount of (1). Accordingly, the network entry node records the specific communication mode (e.g., mode M) of the node 1 ₁₁ ) And response information. The first preset period (i.e. the mode switching period) of the node to be networked may be greater than the period in which the networking node broadcasts the networking beacon frame (i.e. the networking node is from M) ₁₁ -M _1i The sum of traversal times of the networking beacon frames is broadcast in turn) to ensure that there is sufficient time in each mode to wait for the receiving networking node to receive the M slave M ₁₁ -M _1i And broadcasting networking beacon frames in sequence. Whereby the network entry node records the specific communication mode (e.g., mode M) of the node 1 ₁₁ 、M ₁₂ ……M _1i ) And its corresponding response message.

In parallel, the node to be networked (e.g., node 1) switches between modes in the R2 set in turn. By analogy, R1, R2, Rm each independently wait for reception in the intra-set communication mode. The network entry node thus records all specific communication modes (i.e. available communication modes) of the node 1 and their corresponding response information.

Therefore, the above networking discovery process may refer to a process of determining an available communication mode between the network access node and the node to be networked and corresponding response information thereof.

In an embodiment, the node to be networked and the network access node may implement time synchronization through a clock beacon broadcast and compensation calibration mechanism. Accordingly, the networking beacon frame may include hierarchical information and time stamp information of the node to be networked.

Specifically, as shown in fig. 4, the network access node keeps the transmit and receive processing delays for each communication mode relatively constant, e.g., scaling the communication mode M ₁₁ …M _1i The time delay of the receiving process of the beacon broadcast transmitted to the corresponding node is recorded as D _M11 …D _M1i 。

For example, a root node uses a highly stable clock such as a crystal oscillator as a reference, and the root node is used as a network access node to perform a communication mode M ₁₁ Broadcast with time stamp T ₀ Of node 1, time T of receiving beacon ₁ ＝T ₀ +D _M11 And so on, the node 1 is used as a network access node and is in a communication mode M _1i Broadcast with time stamp T ₁ Of node 2, time T of reception of the beacon ₂ ＝T ₁ +D _M1i . Whether mode M is adopted ₁₁ …M _1i In any communication mode, corresponding compensation calibration is performed, so that time synchronization among the nodes is realized. Namely, the physical layer transceiver modules of the multiple communication modes of the multimode communication device have a time synchronization mechanism therebetween.

And step S102, the network access node and the node to be accessed are used for locking the optimal communication mode in each communication mode set into handshake information between the network access node and the node to be accessed according to the received response information through a networking negotiation process.

And selecting at most one optimal communication mode from each communication mode set in the plurality of communication mode sets to obtain a plurality of optimal communication modes, wherein the optimal communication modes are adopted at the same time in the communication process.

Only one optimal communication mode is configured at most at the same time in the communication process for each communication mode set, so that a plurality of optimal communication modes (which can be realized by time slot allocation) can be selected from the plurality of communication mode sets to transmit in a multi-mode manner. For example, an optimal communication mode can be selected from 5 communication mode sets respectively to obtain 5 optimal communication modes; or an optimal communication mode may be selected from the first 4 sets of communication modes in the 5 sets of communication modes, respectively (i.e., the optimal communication mode is not selected from the last set), so as to obtain the 4 optimal communication modes. Specifically, for a node combination composed of any two adjacent layers of nodes, at most, only one optimal communication mode in the same communication mode set can be used for communication, time division multiplexing is performed, and otherwise, two modes in the same set interfere with each other. Therefore, the multiple modes can be reasonably distributed in time, so that the multiple modes are fully utilized for communication, and the communication quality is improved.

For step S102, the locking the optimal communication mode in each communication mode set as the handshake information between the network entry node and the node to be networked may include: according to the response information, the network access node selects the optimal communication mode between the network access node and the node to be accessed from each communication mode set, and broadcasts a communication mode negotiation frame in the optimal communication mode, wherein the communication mode negotiation frame comprises the optimal communication mode in each communication mode set and the address of the node to be accessed; and receiving the communication mode negotiation frame by the node to be accessed, locking the optimal communication mode in each communication mode set in the communication mode negotiation frame as handshake information between the node to be accessed and the network access node under the condition that the actual address of the node to be accessed is matched with the address of the node to be accessed in the communication mode negotiation frame, and feeding the handshake information back to the network access node.

More specifically, the receiving, by the node to be networked, the communication mode negotiation frame may include: and the node to be accessed to the network sequentially switches one communication mode in each communication mode set according to a second preset period so as to execute the receiving operation of the communication mode negotiation frame. Accordingly, the locking the optimal communication mode in each communication mode set in the communication mode negotiation frame as the handshake information between the network entry node and the node to be networked may include: and under the condition that the times of receiving the communication mode negotiation frame by the optimal communication mode meet the preset times and the matching times of the actual address meet the preset times, the optimal communication mode is locked as the handshake information by the node to be accessed to the network. And, the handshake information may be fed back to the network access node in the optimal communication mode.

The communication mode negotiation stage mainly includes the following processes executed by the network access node and the node to be accessed.

According to the received response information, the network access node selects a communication mode with the optimal channel quality between the network access node and the node to be accessed from each mode set in the R1-Rm sets.

Taking the R1 set as an example, the network access node determines the communication mode with the best channel quality (for example, the mode M shown in fig. 5) between the network access node and the node to be networked according to the signal attenuation of the available communication mode in the response message _1o ). And, the network access node passes through the optimal communication mode M _1o Broadcasting a communication mode negotiation frame, wherein the communication mode negotiation frame may include an optimal communication mode M _1o And the address of the node to be networked (whereby only the node to be networked having the corresponding address can receive the communication mode negotiation frame).

Correspondingly, all the nodes to be accessed switch each mode in the R1 set in turn in a second preset period, receive the communication mode negotiation frame, and only when the actual address of a certain node to be accessed matches the address of the node to be accessed included in the negotiation frame, the following mode locking step may be performed. Once a node to be networked (e.g., node 1) receives a communication mode negotiation frame sent by the network access node once or several times (e.g., twice as shown in fig. 5), and the actual addresses all match, node 1 locks in the communication mode M _1o Handshaking, i.e. putting said communication mode M into _1o As the network access node andand handshake information between the nodes 1, thereby completing communication mode negotiation between the network access node and the nodes 1.

By analogy, R2-Rm conducts communication mode negotiations in parallel.

Therefore, the networking negotiation process may refer to a process of determining handshake information between the network access node and the node to be networked (i.e., locking an optimal communication mode in each communication mode set).

Through steps S101-S102, an optimal communication mode in each communication set available for communication between any two adjacent layers of nodes can be determined, and the optimal communication mode can be switched according to the change of an actual channel. For example, the communication quality of each used communication mode can be regularly monitored, and if the communication quality is lower than a preset threshold, the communication mode is switched, so that the communication quality is effectively guaranteed.

And step S103, the network access node reports the routing information between the network access node and the node to be accessed to a root node according to the handshake information through a routing establishment process so that the root node can update networking routing information.

For step S103, the reporting, to the root node, the routing information between the network access node and the node to be networked according to the handshake information may include: according to the handshake information, the network access node establishes routing information between the network access node and the node to be accessed; and reporting the routing information to the root node by the network access node.

The establishment of the networking route mainly comprises the following processes executed by the network access node and the node to be accessed.

And the network access node initiates the establishment of the next-level route according to the handshake information, so that the network access node of the next level accesses the network, and the established route information between the network access node and the network access node comprises the optimal communication mode information. The network access node reports the established routing information to the root node, so that the root node updates the networking routing information (i.e., updates the routing information table shown in table 1).

Therefore, the route establishment procedure may refer to a procedure of establishing route information between the network entry node and the node to be networked.

In an embodiment, the networking method may further include: and responding to the updating of the root node and sending the networking routing information, and receiving and storing the networking routing information by the network access node and the node to be accessed.

Specifically, after the root node updates the networking routing information, the root node also sends the networking routing information to all nodes on a path including corresponding network access nodes and nodes to be accessed in a networking architecture in a layer-by-layer broadcast manner, and thus, the network access nodes and the nodes to be accessed can receive and store the networking routing information so that it is clear which nodes in the next layer of nodes have been accessed and which nodes have not been accessed (i.e., are still nodes to be accessed).

In an embodiment, the networking method may further include: responding to the root node to update the networking routing information, and executing role updating operation by the node to be accessed to update the node to be accessed to a new network access node; and executing the following operations according to whether the new network access node meets a preset end condition or not: under the condition that the new network access node does not meet the preset end condition, locking an optimal communication mode in each communication mode set between the new network access node and a next layer of network access node as handshake information through the network configuration discovery process and the network configuration negotiation process, and reporting routing information between the new network access node and the next layer of network access node to a root node through a routing establishment process according to the handshake information by the new network access node so that the root node can update networking routing information; or upon receiving feedback that the new network entry node determined by the root node satisfies the preset end conditionLove of a personUnder the condition, the content of the new network access node in the networking routing information is confirmed to be updated.

Wherein the preset ending condition may include: receiving no response information within a first preset time period after the feedback broadcast networking beacon frame; the next-layer nodes of the new network access nodes are all accessed to the network (specifically, after all nodes in the platform area file (i.e. networking architecture) stored by the root node are compared with the accessed nodes, it is determined that all nodes in the platform area file are accessed to the network); or the hierarchy of the new network access node is the maximum hierarchy of the networking architecture.

Specifically, after the root node updates networking routing information, the node to be accessed is indicated to be successfully accessed, and at the moment, the node to be accessed switches the role of the node to be accessed into a new network access node. Then, the root node judges whether the new network access node meets a preset end condition. If yes, the networking process about the new network access node is finished. If the answer is not met, the new network access node and the node to be accessed to the next layer lock corresponding handshake information through the networking discovery process and the networking negotiation process, and then report the routing information between the new network access node and the node to be accessed to the next layer to the root node through a routing establishment process according to the handshake information so as to update the networking routing information by the root node; and repeating the operation until the preset ending condition is met, and indicating that the networking process is ended.

The foregoing embodiments are only described for a node to be networked, and similarly, the processes of the stages of network discovery, communication mode negotiation, and network routing establishment of other nodes to be networked are similar to the above processes, and are not described herein again. Thus, the entire network can be established through the above-described procedure.

For example, in the routing information table, there may be an optimal communication mode between two nodes in each of the sets R1-Rm, or in only one or some of the sets. The routing information table also contains statistics of communication success rates of the two nodes in the selected mode.

Table 1 routing information table

Wherein the PCO represents a proxy master node.

Specifically, the following is a general description of the networking process, as shown in fig. 6.

As shown in fig. 6, the networking process may include the following steps S601-S609.

Step S601, selecting a root node as a network access node and a first layer node a as a node to be accessed to the network.

In step S602, the root node broadcasts beacon frames in different communication modes in sequence and receives response frames.

Step S602 is a networking discovery phase, where the response frame may include an address of the first layer node a, an available communication mode between the root node and the first layer node a, and a characteristic parameter characterizing channel quality of the root node.

Step S603, the root node selects an optimal communication mode according to the response frame, and broadcasts the negotiation frame in the optimal communication mode.

Step S604, the first layer node a receives the negotiation frame and locks the handshake information in the optimal communication mode, and feeds back the handshake information to the root node.

The steps S603-S604 are communication mode negotiation stages, and the optimal communication mode includes an optimal communication mode in each mode set.

Step S605, the root node establishes its route with the first-layer node a according to the handshake information.

Wherein the handshake information includes the optimal communication information.

Step S606, reporting the corresponding routing information to the root node, so that the root node can update the routing information table.

The steps S605 to S606 are a networking route establishing stage, and the corresponding routing information includes an optimal communication mode for each mode set between the root node and the first layer node a.

Step S607, determining whether the root node satisfies a preset stop condition, if yes, executing step S608; otherwise, step S609 is executed.

Step S608, continue to execute the route establishment procedure between the first layer node and the second layer node until all nodes in the entire networking have accessed the network.

Step S609, continue to execute the route establishment procedure between the root node and other nodes in the first layer until all nodes in the entire networking have accessed the network.

Wherein, the information of the whole networking architecture (from the root node to the network relationship between each layer of nodes) is stored in the root node.

Therefore, each node may perform the networking discovery, communication mode negotiation, networking route establishment procedures. Firstly, selecting a root node as a networking node for networking discovery, and performing networking discovery, communication mode negotiation and networking route establishment on a first-level node; then, selecting a first-level network access node as a network access node for networking discovery, and performing networking discovery, communication mode negotiation and networking route establishment on a second-level node; and so on. When a networking end condition is reached (for example, the networking time is reached or all the nodes in the root node CCO discovery list are already accessed), networking is completed.

Before networking, the available communication modes between the nodes are detected through multi-mode networking discovery, networking negotiation, networking route establishment and the like, and the communication quality is analyzed to determine the optimal communication mode, so that the communication performance after networking is ensured.

In summary, the present invention creatively configures communication modes incompatible with each other into the same communication mode set, determines an optimal communication mode in each communication mode set available for communication between any two adjacent layers of nodes through a networking discovery process, a communication mode negotiation process and a routing establishment process, and configures at most only one optimal communication mode in the same communication mode set at the same time, so that a plurality of mutually compatible optimal communication modes between any two adjacent layers of nodes can be determined, thereby ensuring high-quality communication performance after networking.

The existing multimode communication modes mainly include the following two modes: (1) the communication is carried out in a relay mode, namely, one mode is preferably adopted for communication generally, and when the communication in the mode is unsuccessful, the communication is switched to another mode to attempt communication; (2) the point-to-point intercommunication is realized by simply adopting the combination of a plurality of communication modes, but serious mutual interference exists among the plurality of modes, so that the communication quality is influenced. None of the above conventional communication methods efficiently utilizes a plurality of communication modes to improve communication quality.

An embodiment of the present invention further provides a communication method, where the communication method may include: updating networking routing information according to the networking method of the multimode communication equipment; and according to the routing information between the first node and the second node which are positioned between every two adjacent layers on the path from the communication starting node to the communication target node in the networking routing information, the communication is carried out between the communication starting node and the communication target node.

The networking method of the multimode communication equipment is adopted to update networking routing information, incompatible communication modes can be configured into the same communication mode set, then the optimal communication mode in each communication mode set which can be used for communication between any two adjacent layers of nodes is determined through a networking discovery process and a networking negotiation process, and only one optimal communication mode in the same communication mode set is configured at most at the same moment, so that a plurality of compatible optimal communication modes between any two adjacent layers of nodes can be determined, high-quality communication performance after networking is ensured, and therefore cooperation among various communication modes can be fully utilized, mixed networking communication is achieved, and channel resources are utilized to the maximum extent.

The communication initiation node and the communication target node may be any two nodes in a networking architecture, and the first node and the second node are nodes located on any upper layer and any lower layer on a communication path between the communication initiation node and the communication target node. Wherein the communication initiation node, the communication target node, the first node and the second node may all be multi-mode communication devices. Of course, the communication initiating node may also be a first node, and the communication target node may also be a second node, i.e. communication is only performed between two nodes, namely the communication initiating node and the communication target node.

In addition to updating the networking routing information according to the networking method of the multimode communication device, in another embodiment, the networking routing information may be determined in advance and stored at the root node, and the acquiring the networking routing information may include: and acquiring the networking routing information from the root node through a routing acquisition device. Specifically, an embodiment of the present invention further provides a communication method, as shown in fig. 10, where the communication method may include: step S1001, obtaining networking routing information, wherein the networking routing information includes routing information between a first node and a second node which are positioned between every two adjacent layers on a path from a communication starting node to a communication target node, the routing information between the first node and the second node includes an optimal communication mode in each of a plurality of communication mode sets between the first node and the second node, the communication modes in each communication mode set are incompatible with each other and the communication modes in different communication mode sets are compatible with each other; and step S1002, according to the routing information between the first node and the second node located at each two adjacent layers on the path from the communication starting node to the communication target node in the networking routing information, performing communication between the communication starting node and the communication target node.

Wherein the networking routing information comprises routing information between a first node and a second node which are positioned between every two adjacent layers on a path from a communication starting node to a communication target node, the routing information between the first node and the second node comprises an optimal communication mode in each of a plurality of communication mode sets between the first node and the second node, the communication modes in each communication mode set are incompatible with each other and the communication modes in different communication mode sets are compatible with each other

According to networking routing information obtained by updating the networking method, the routing information between the first node and the second node comprises optimal communication modes aiming at each communication mode set, and because conflicts and interferences exist among the optimal communication modes in the same communication mode set, a time slot allocation mode can be adopted for synchronization; while the optimal communication modes in different sets do not affect each other, they can communicate simultaneously or in time sharing.

In an embodiment, the communicating between the communication initiation node and the communication target node may include: and according to the routing information between the first node and the second node positioned at any two adjacent layers, carrying out communication between the first node and the second node.

The following description is only given of the communication process between the first node and the second node on one adjacent two layers, and the communication process on the other adjacent two layers is similar to the above.

Wherein the performing communication between the first node and the second node according to the routing information between the first node and the second node located in any two adjacent layers may include: respectively carrying out time slot allocation on the optimal communication mode in each communication mode set in the routing information so as to select at most one optimal communication mode from each communication mode set in the plurality of communication mode sets to obtain a plurality of optimal communication modes, wherein the optimal communication modes are adopted at the same time in the communication process; and communicating between the first node and the second node according to an optimal communication mode in each communication mode set of the allocated time slots.

Specifically, the slot allocations of R1, R2, and R3 as shown in fig. 7 are completely independent. For example, the optimal communication modes in different sets do not affect each other, and can be communicated simultaneously or in a time-sharing manner; and for the optimal communication modes in the same set R3, time-sharing communication is carried out by adopting a time slot allocation mode, so that only one optimal communication mode in the same set R3 is ensured to be adopted at most at the same time. Since the same preset communication mode is provided in the same set, the CSMA method can be adopted for competing communication. In fact, the root node can perform time slot allocation according to the scale of the networking network and the optimal communication mode, and the time slot allocation result is broadcasted to the whole network by the root node in a beacon mode. For example, the root node broadcasts in the current period or transmits the timeslot allocation information of the next period by adopting a TDMA or CSMA mode.

In addition to the existing multimode communication method, generally, communication is performed by selecting an optimal communication mode from a plurality of communication modes only according to a traffic type, or by selecting an optimal communication mode from a plurality of communication modes only according to parameters such as a load of a communication network. However, the above communication method cannot provide an adaptive communication mode for various application scenarios in real time by considering both the service requirement and the network capability.

In an embodiment, more specifically, the step of communicating between the first node and the second node according to an optimal communication mode in each communication mode set of allocated timeslots may include: selecting a specific mode selection strategy from a plurality of mode selection strategies according to the service type; determining a plurality of allocated optimal communication modes at the current moment according to the optimal communication mode in each communication mode set of the allocated time slot; counting the channel occupancy rate and the communication success rate of the optimal communication modes in a second preset time before the current moment; selecting a specific communication mode from the optimal communication modes according to the specific mode selection strategy, the counted channel occupancy rate and the communication success rate; and communicating between the first node and the second node in the specific communication mode at the current time.

Wherein the plurality of mode selection policies may include: a maximum efficiency strategy, a maximum reliability strategy and a load balancing strategy.

Specifically, for example, a first node sends information to a second node, first, a communication data frame carries an identifier of a service type, and the first node selects different mode selection policies according to the identifier of the service type. When the service type identification indicates that the service type has high real-time requirement on data, a highest efficiency strategy can be adopted; when the service type identification indicates that the service type is data communication with high reliability requirements such as closing and stopping, charge control and the like, a maximum reliability strategy can be adopted; and when the identification of the service type indicates that the service type is large in data volume and busy in communication traffic, a load balancing strategy can be adopted.

Then, the first node may determine a plurality of allocated optimal communication modes at the current time according to the optimal communication mode in each communication mode set of the allocated time slot. Then, according to the selected specific mode selection policy, the first node selects a specific communication mode from the plurality of optimal communication modes. And finally, at the current time, the first node sends the data frame to the second node by adopting the selected specific communication mode. Therefore, a proper communication mode is selected from the optimal communication modes of different sets according to different strategies for communication, and the efficiency and the reliability of data transmission are greatly improved.

In an embodiment, in the case that the specific communication mode is the highest efficiency policy, the selecting the specific communication mode from the plurality of optimal communication modes includes: determining the communication bandwidth of each optimal communication mode in the plurality of optimal communication modes within the second preset time according to the counted channel occupancy rate and the communication success rate; and selecting the specific communication mode meeting the target communication bandwidth required by the data to be transmitted from the optimal communication modes according to the communication bandwidth of each optimal communication mode in the second preset time.

Wherein a communication bandwidth of the particular communication mode may be greater than communication bandwidths of other of the plurality of optimal communication modes.

Specifically, the selecting the specific communication mode from the plurality of optimal communication modes that satisfies the target communication bandwidth required for the data to be transmitted may include: ranking the optimal communication modes in a communication bandwidth descending manner; and according to the communication bandwidths of the ranked optimal communication modes and the target communication bandwidth, executing the following operations: and determining the first-ranked optimal communication mode as the specific communication mode when the communication bandwidth of the first-ranked optimal communication mode is greater than or equal to the target communication bandwidth, or determining the first-ranked L + 1-ranked optimal communication mode as the specific communication mode when the total communication bandwidth of the first-ranked L-ranked optimal communication mode is less than the target communication bandwidth and the total communication bandwidth of the first-ranked L + 1-ranked optimal communication mode is greater than or equal to the target communication bandwidth, wherein L is a positive integer.

Specifically, taking the communication between the first node and the second node at time t as an example, according to the optimal communication mode in each communication mode set of the allocated time slot, a plurality of optimal communication modes at the current time t that are allocated may be determined. A period of time T before T _total The acquisition process of the channel occupancy rate, the channel collision probability and the communication success rate in each of the plurality of optimal communication modes in the mobile communication system is explained.

For example, the second node opens the receiving channel in the optimal communication modes, and counts a period of time T in each optimal communication mode _total Total number of received data frames Num (F) _total ) Total number of colliding data frames Num (F) _collision ) And total time sigma T of busy channel operation _busy Calculating a period of time T _total Within said each optimal communication mode, a channel occupancy TD _Duty Probability of channel collision r _collision And communication success rate r _success (ii) a According to the three parameters obtained by statistics, the available state of each optimal communication mode can be determined,

then, the theoretical communication rate R for each optimal communication mode in R1-Rm _theory Estimation is made from the physical layer bandwidth R _PHY Application layer loading efficiency η _APP CSMA Slot efficiency eta _CSMA Communication success rate r _success Level H _Layer Estimating theoretical communication rate:

then, the theoretical communication rate R according to each optimal communication mode in R1-Rm _theory Calculating a period of time T _total A communication bandwidth R of each of the optimal communication modes _available ：

R _available ＝R _theory ×(1-TD _Duty )。

Of course, the communication bandwidth R of each of the above-described optimum communication modes _available Or can be obtained in advance and directly used as an input parameter.

Finally, according to the communication bandwidth R of each optimal communication mode _available Selecting a target communication bandwidth R meeting the requirement of transmitting data to be transmitted from a plurality of optimal communication modes at the current moment _require To communicate in a particular communication mode. Wherein the particular communication mode may be one or more modes but the communication bandwidth of the one or more modes is greater than the bandwidth of the other modes of the plurality of optimal communication modes.

For example, a plurality of optimal communication modes at the present time are ranked in descending order of communication bandwidth. If the communication bandwidth of the first-ranked optimal communication mode (i.e., the optimal communication mode with the largest communication bandwidth) is greater than or equal to the target communication bandwidth, selecting the first-ranked optimal communication mode as the specific communication mode. And if the total communication bandwidth of the top-ranked 1-bit optimal communication mode is less than the target communication bandwidth and the total communication bandwidth of the top-ranked 2-bit optimal communication mode is greater than or equal to the target communication bandwidth, selecting the top-ranked 2-bit two communication modes as the specific communication mode. During the communication, the communication data can be allocated to the two communication modes according to the bandwidth ratio for transmission, so as to improve the communication efficiency.

In an embodiment, in the case that the specific communication mode is the maximum reliability policy, the selecting the specific communication mode from the plurality of optimal communication modes may include: determining a communication reliability parameter of each optimal communication mode in the plurality of optimal communication modes within the second preset time according to the counted communication success rate; and selecting the specific communication mode from the plurality of optimal communication modes according to the reliability level required by the data to be transmitted and the communication reliability parameter of each optimal communication mode in the second preset time.

Specifically, the step of selecting the specific communication mode from the multiple optimal communication modes according to the reliability level required by the data to be transmitted and the communication reliability parameter of each optimal communication mode in the second preset time may include: ranking the optimal communication modes in a communication reliability parameter descending manner; and according to the communication reliability parameters of the ranked optimal communication modes and the reliability level required by the data to be transmitted, executing the following operations: determining an optimal communication mode with M bits before ranking as the specific communication mode under the condition that the reliability level required by the data to be transmitted is the highest level, wherein M is a positive integer; under the condition that the reliability level required by the data to be transmitted is a medium level, randomly determining one of S-bit optimal communication modes before ranking as the specific communication mode, wherein S is a positive integer greater than 1; or randomly determining one of the plurality of optimal communication modes as the specific communication mode under the condition that the reliability level required by the data to be transmitted is the lowest level.

First, for each optimal communication mode in R1-Rm, over a period of time T _total Inner communication reliability parameter Q _reliablity And (6) estimating. In particular, according to the maximum time delay T of the data communication _maxdelay Minimum period T for requesting and transmitting data _send Determining the number of retransmissions N _retry And the formula; and according to the communication success rate r _success Number of retransmissions N _retry And calculating each optimal communication pattern over a period of time T _total Inner communication reliability parameter Q _reliablity ，

Finally, according to the reliability grade needed by the data to be transmitted and each optimal communication mode in a period of time T _total And selecting a specific communication mode from a plurality of optimal communication modes at the current time t for communication according to the communication reliability parameters. Wherein the particular communication mode may be one or more modes.

For example, the plurality of optimal communication modes at the current time t are ranked in a descending order of the communication reliability parameters. And if the reliability grade is the highest grade, determining the optimal communication mode with 2 top-ranked bits as the specific communication mode. If the reliability is of a medium level, one of the top 5 ranked optimal communication modes is randomly selected as the particular communication mode. Randomly selecting one of a plurality of optimal communication modes as the specific communication mode if the reliability is the lowest level; or not selecting the maximum reliability strategy and combining the maximum efficiency strategy or the load balancing strategy to select the specific communication mode for communication.

In an embodiment, in the case that the specific communication mode is the load balancing policy, the selecting the specific communication mode from the plurality of optimal communication modes may include: determining the communication bandwidth and the channel occupancy rate of each optimal communication mode in the plurality of optimal communication modes within the second preset time according to the counted channel occupancy rate and the communication success rate; and selecting the specific communication mode meeting the target communication bandwidth required by the data to be transmitted from the plurality of optimal communication modes according to the communication bandwidth and the channel occupancy rate of each optimal communication mode in the second preset time.

Wherein the channel occupancy of the particular communication mode may be greater than the channel occupancy of other ones of the plurality of optimal communication modes.

Specifically, the selecting the specific communication mode from the plurality of optimal communication modes that satisfies the target communication bandwidth required for the data to be transmitted may include: ranking the optimal communication modes in an ascending way of channel occupancy rate; and determining the T-bit top-ranked optimal communication mode as the specific communication mode under the condition that the total communication bandwidth of the T-bit top-ranked optimal communication mode is larger than or equal to the target communication bandwidth, wherein T is a positive integer.

First, it is determined that each optimal communication pattern in R1-Rm is over a period of time T _total Inner communication bandwidth R _available (the specific procedures can be referred to as the related contents in the above maximum efficiency policy) and the occupancy rate TD _Duty 。

Then, according to the target communication bandwidth needed by the data to be transmitted and each optimal communication mode, in a period of time T _total Inner communication bandwidth R _available And channel occupancy TD _Duty And selecting a specific communication mode meeting the target communication bandwidth required by the data to be transmitted from a plurality of optimal communication modes at the current moment t for communication. Wherein the particular communication mode may be one or more modes but the one or more modes have a duty cycle greater than the duty cycles of the other ones of the plurality of optimal communication modes.

For example, the plurality of optimal communication modes at the current time t are ranked in an ascending order of the channel occupancy. If the communication bandwidth of the first-ranked optimal communication mode (i.e., the optimal communication mode with the minimum channel occupancy) is greater than or equal to the target communication bandwidth, selecting the first-ranked optimal communication mode as the specific communication mode. And if the total communication bandwidth of the top 2 optimal communication modes is greater than or equal to the target communication bandwidth, selecting the top 2 two optimal communication modes as the specific communication mode so as to improve the communication efficiency and achieve load balance.

Of course, other strategies can be set, a mode with low energy consumption can be selected for sending, and communication energy consumption under the scene of battery power supply is saved.

In an embodiment, if the first node simultaneously transmits data frames in different modes, dynamic power consumption generated by the simultaneous transmission is estimated, and once the dynamic power consumption limit is exceeded, the multiple modes are staggered in time to ensure that power consumption requirements are met, so that power consumption combination control of different transmission modes is realized.

The step of communicating between the first node and the second node according to an optimal communication mode of the each communication mode set of allocated timeslots may comprise: and performing communication between the first node and the second node according to the optimal communication mode and the power consumption control strategy in each communication mode set of the allocated time slot (or according to the routing information between the first node and the second node positioned at any two adjacent layers and the power consumption control strategy).

More specifically, the step of communicating between the first node and the second node according to the optimal communication mode and power consumption control strategy in each communication mode set of the allocated time slots may include: under the condition that the total power consumption of a first optimal communication mode group which is executing communication at the current distributed time and a second optimal communication mode group which starts to execute communication exceeds a power consumption threshold value, delaying the starting time of the second optimal communication mode group to a first time; determining the total power consumption of the third optimal communication mode group, on which communication is to be performed, and the fourth optimal communication mode group, on which communication is to be started, at the first time point that have been allocated; and under the condition that the total power consumption of a third optimal communication mode group which is executing communication and a fourth optimal communication mode group which is about to start executing communication at the first time is less than or equal to the power consumption threshold value, adopting the first optimal communication mode group of the allocated time slot from the current time to the first time to carry out communication between the first node and the second node.

Wherein the fourth optimal communication mode group may include at least the second optimal communication mode group.

Recording Q as the mode set being sent at the time t, the mode i belongs to Q and P _i (t) is the movement of pattern i transmission at t timeState power consumption; recording G as a mode set to be sent at the moment t, wherein a mode j belongs to G and P _j And (t) is the dynamic power consumption of the mode j in the time t. P is _tot (t) is the total dynamic power consumption of the transmission, which can be calculated by the formula:

once P is present _tot (t) exceeds a power consumption threshold (i.e., a dynamic power consumption limit P _max ) And delaying the modes in the mode set G to be transmitted by delta t in time to ensure whether the total power consumption at the time of t plus delta t meets the power consumption limitation requirement or not. Specifically, the transmission start time of the pattern in the pattern set G and the end time of the communication pattern that ends the first bit (i.e., ends earliest) in the pattern set Q may be staggered, and it is determined whether the total power consumption at the time t +. DELTA.t satisfies the power consumption limitation requirement, and if so, the corresponding Δ t is determined; otherwise, staggering the sending start time of the mode in the mode set G and the ending time of the communication mode ending at the second time in the mode set Q, and determining whether the power consumption at the time of t plus delta t meets the power consumption limiting requirement, and so on until determining the corresponding delta t.

Let Q ' be the set of patterns being transmitted at time t +. DELTA.t, with pattern i ' being for Q ', P _i’ (t + Deltat) is the dynamic power consumption when the mode i' is transmitted at the time of t + Deltat; let G ' be the set of patterns starting to be transmitted at time t +. DELTA.t (which includes at least the set of patterns G), pattern j ' e.Q ', P _j’ And (t +. DELTA.t) is the dynamic power consumption of the lower mode j' at time t during transmission. P _tot (t +. DELTA.t) is the total dynamic power consumption of the transmission (i.e., the total power consumption at time t +. DELTA.t) can be determined by:

as shown in FIG. 8A, at time t1, the pattern M is being transmitted ₁₁ And M ₂₁ Power consumption of and mode M to start transmitting ₃₂ Is greater than a power consumption threshold,then the mode M ₃₂ Delaying until time t2 (i.e., mode M) ₁₁ Time after the end); m being transmitted at time t2 ₂₁ Power consumption of and mode M to start transmitting ₃₂ Is less than or equal to the power consumption threshold, then M of mode allocated slots is employed during time t1 to time t2 ₁₁ And M ₂₁ And sending the data.

As shown in FIG. 8B, the pattern M being transmitted at time t1 ₁₁ 、M ₂₁ And M ₄₁ Power consumption of and mode M to start transmitting ₃₂ Is greater than the power consumption threshold, the mode M is set ₃₂ Delaying until time t2 (i.e., mode M) ₁₁ Time after the end); but pattern M being transmitted at time t2 ₂₁ And M ₄₁ Power consumption of and mode M to start transmitting ₃₂ Is still greater than the power consumption threshold, the mode M will be entered ₃₂ Delaying until time t3 (i.e., mode M) ₂₁ Time after the end), the pattern M being transmitted at time t3 ₄₁ With mode M to start transmission ₃₂ Is less than or equal to the power consumption threshold, then the mode M of allocated slots is employed during time t1 to time t3 ₁₁ 、M ₂₁ And M ₄₁ And sending the data.

According to the embodiment, the communication performance and the system reliability can be greatly improved through the extended functions such as dynamic power consumption control and the like, so that the adaptability to the external power consumption limiting scene is improved.

In an embodiment, the communication method may further include: in the event that the first node or the second node receives a group of data frames, performing the following: filtering data frames in the group of data frames that are repeated with historical data; and/or combining the data frame groups in the plurality of optimal communication modes to form a complete data frame.

Taking an example that a first node sends a data frame group to a second node, the first node sends the data frame group in different modes, at this time, the second node receives the data frame group in different modes, records channel state information such as a serial number, a source address, a destination address and the like of the data frame, and compares the different data frame groups with a history record to filter repeated data frames (the serial number, the source address and the destination address are completely the same and only belong to repeated data). As shown in fig. 9A, the node 1 transmits data frames 1, 2 in mode 1, and simultaneously transmits data frames 1, 2, 3 in mode 2; and the node 2 receives the data and then filters the data to obtain complete data frame sequence data frames 1-3.

Similarly, the second node receives the data frame group in different modes and records the channel state information of the data frame, such as the serial number, the source address, the destination address and the like; the data in the different modes may then be combined to form a complete data frame. As shown in fig. 9B, the node 1 transmits data frames 1-1 and 1-4 in mode 1, and simultaneously transmits data frames 1-2 and 1-3 in mode 2; nodes 2, upon receiving the data, combine to obtain a complete sequence of data frames (i.e., data frame 1, which includes data frames 1-1, 1-2, 1-3, 1-4).

Specifically, the process of selecting different communication policies according to the demand type of the service includes the following steps S1101-S1107, as shown in fig. 11.

Step S1101, receiving a service requirement.

Step S1102, determining whether the service requirement is a high reliability requirement, if yes, executing step S1103; otherwise, step S1104 is performed.

Step S1103, a maximum reliability policy is adopted.

For data communication with high reliability requirements such as closing and stopping, charge control and the like, the single communication data volume is small, and the requirements on the success rate of communication are extremely high due to charge settlement and power-on stopping control of a user.

The communication may be performed in a mode with the highest communication success rate and the least interference by considering the reliability level, or in a mode of simultaneously using a plurality of modes, etc. through step S1103, so as to ensure the corresponding reliability of the communication.

Step S1104, determining whether the service requirement is a high real-time requirement, if so, executing step S1105; otherwise, step S1106 is executed.

Step S1105, a maximum efficiency strategy is adopted.

For application scenarios such as high-frequency acquisition and station area identification, the data volume of a single communication mode is small, nodes in the station area have a large amount of aggregated communication demands, and a highest efficiency strategy can be adopted to meet the requirement of high efficiency.

In step S1105, communication can be performed in the mode with the largest bandwidth or the mode with the first few bits of bandwidth, so as to improve communication efficiency.

Step S1106, determining whether the service requirement is that the bandwidth of the single mode meets the target bandwidth requirement, if yes, executing step S1105; otherwise, step S1107 is executed.

Step S1107, a load balancing policy is adopted.

For the application scenes of freezing data acquisition, minute-level data acquisition and curve data acquisition superposition, the data volume acquired at a single time is large, a single curve data packet reaches 2KB, the communication traffic volume of the minute-level data acquisition is quite heavy, each node is required to acquire data once in 1-5 minutes, according to the typical area size of 300 users, the average requirement is 0.2s, the channel is quite heavy, and therefore the acquisition with the large data volume can be arranged in an idle channel mode, or the data can be distributed to a plurality of modes for parallel transmission, and the load balancing effect is achieved.
