Description

Collaborative communication method and system, network access node, CCO, storage medium and chip

Technical Field

The invention relates to the field of communication, in particular to a cooperative communication method and system, a network access node, a CCO, a storage medium and a chip.

Background

The power distribution internet of things relates to a cloud management side end technical architecture, wherein a pipe layer is used as a data transmission channel of a cloud, a side and an end of the power distribution internet of things and is used for bearing various services of the power distribution internet of things, and the data transmission channel is important in the construction of the power distribution internet of things. The "pipe" layer adopts the technical architecture of "remote communication network+local communication network".

The remote communication access network refers to a communication access network in which an end service terminal (such as a sensor, a meter, a DTU, an electric vehicle charging pile and the like) or an edge convergence terminal (such as a concentrator, an edge internet of things proxy device, a power transmission line state monitoring proxy and the like) is directly connected with a backbone communication network. The remote communication access network mainly adopts optical fiber communication, wireless public network communication, wireless private network communication and the like, and mainly meets the communication requirements of high reliability, low time delay and differentiation between the power distribution cloud platform and the edge computing terminal. And the local communication access network refers to a communication access network in which the terminal service terminal is connected with the edge aggregation terminal. The local communication access network mainly adopts a low-voltage power line carrier, micropower wireless communication, a local Ethernet, serial communication and the like, and meets the requirements of reliable transmission and communication of service data between the edge computing terminal and the low-voltage intelligent equipment.

Along with the promotion of the construction of the distribution internet of things, the construction of the fusion terminal is of a first scale, the cloud platform also has realized basic functions, and low-voltage equipment also has formed products. However, a complete solution is not available in the aspect of local communication, and the solution has become a factor for restricting the development of the internet of things for power distribution.

Currently, the existing local communication technologies of the marketing network mainly include high-speed power line carrier (HPLC) communication, micro-power wireless (RF X470 MHz) Wi-SUN RF (920 MHz) communication, hplc+rf dual-mode communication, and other communication modes. The local communication mode of the distribution network can adopt the local communication technical scheme of the marketing network under the condition that unified standards are not specified at present. Marketing network a large number of deployment HPLC networks, distribution network and marketing network coexistence generally adopt the mode of frequency division or same frequency.

The operating frequency range of HPLC communication comprises 4 frequency bands: band 0:2 MHz-12 MHz, band 1:2.4 MHz-5.6 MHz, frequency band 2:0.7 MHz-3 MHz, band 3:1.7MHz ~ 3MHz can provide the data transmission rate of hundreds kbps to several Mbps to the power line is relatively weaker in the noise of high frequency channel, and relative to narrowband power line communication, communication reliability and stability are showing and are improving. In the actual application field, the frequency band 2 is mainly used; and the station area with large noise interference is switched to the frequency band 1 for use. If the power distribution network uses the frequency band 1 for large-scale use, the attenuation of the high frequency band is larger, and the power distribution network cannot be suitable for all the areas; the two frequency bands work simultaneously on the same line, out-of-band leakage can affect each other, and in-band interference can be formed for a site area with large individual noise. The power distribution network may need to be customized according to the extended frequency band.

When the power distribution network and the marketing network are in the same frequency, the existing carrier protocol prescribes a multi-subnet bandwidth coordination mechanism to realize the interleaving of each subnet beacon time slot area on a time axis, but related researches show that the mechanism is influenced by the typical 'hidden terminal' problem of the multi-hop network, and the mechanism can solve the interference among different subnets beacon signals, but can not effectively solve the problem that the transmission process of one subnet beacon signal is interfered by other subnets non-beacon signals, and the transmission effect of the beacon signal is greatly influenced under the condition of high network service load. The distribution and marketing of a large number of devices are interleaved with one another, making inter-network coordination more complex, and the marketing network does not necessarily agree to actively dodge the distribution network.

Detailed Description

The following describes specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.

Before describing the various embodiments of the present invention, several english abbreviations in the present invention are explained. HPLC: high-speed power line carrier communication; HRF: high-speed wireless communication; CCO: a central coordinator; and (3) STA: a station; PCO: the proxy node (PCO may also be connected to other PCOs or STAs, while STAs are the last-level nodes and no longer connected to other nodes); TEI: a source terminal device identifier; CSMA-CA: carrier sense multiple access with collision avoidance.

Fig. 1 is a flowchart of a cooperative communication method according to an embodiment of the present invention. The cooperative communication method is applied to network access nodes. As shown in fig. 1, the cooperative communication method may include: step S101, in response to CCO updating a node to be accessed to a network as the node accessing to the network of a power distribution network, detecting whether a conflict exists between beacon time slots of the power distribution network and a non-power distribution network; step S102, judging whether the beacon time slot of the network access node falls into the beacon time slot of the non-power distribution network or not under the condition that the beacon time slots of the power distribution network and the non-power distribution network collide; and step S103, according to the judging result, adopting the HRF link or adopting both the HPLC link and the HRF link to send the beacon frame.

Wherein the non-distribution network may be any non-distribution network that uses HPLC communication and RF communication as local communication. For example, the non-distribution network may be a marketing network.

The following explanation and explanation are made with respect to the details of the above steps S101 to S103, respectively.

Step S101, in response to updating a node to be network-accessed into the network-accessed node of a power distribution network by CCO, whether a conflict exists between beacon time slots of the power distribution network and a non-power distribution network is detected.

Wherein the network access node is a PCO (e.g., PCO1, PCO2, PCO3, PCO 4) or a STA (e.g., STA1, STA2, STA3, STA 4).

If CCO updates the node to be network-connected into the network-connected node, the network-connection process of the node to be network-connected is indicated to be completed, and the role of the node to be network-connected is converted into the network-connected node. Thereafter, it may be detected whether there is a collision of beacon slots of the distribution network with the non-distribution network by means of an inter-network coordination frame or any existing manner.

Step S102, determining whether the beacon slot of the network node falls into the beacon slot of the non-power distribution network if there is a conflict between the beacon slots of the power distribution network and the non-power distribution network.

As shown in fig. 2, the power distribution network in the same area collides with the beacon slot of the marketing network, in this case, it is continuously determined whether the beacon slot of the network access node falls into the beacon slot of the marketing network: for example, the beacon slots of PCO1, PCO2 fall entirely within the beacon slots of the marketing network; the beacon time slots of PCO3, PCO4 and STA 1-STA 4 fall in the CSMA-CA time slots of the marketing network, and do not fall in the beacon time slots of the marketing network.

In an embodiment, the cooperative communication method may further include: in the event that there is no conflict in beacon slots of the distribution network and the non-distribution network, both HPLC links and HRF links are employed to transmit beacon frames.

For example, through the detection process of step S101, if there is no conflict between the beacon slots of the distribution network and the marketing network, the beacon frame is sent by adopting two communication modes, that is, the HPLC link and the HRF link.

Step S103, according to the judging result, adopting the HRF link or adopting both the HPLC link and the HRF link to send the beacon frame.

For step S103, the transmitting the beacon frame using the HRF link or using both the HPLC link and the HRF link may include: when the beacon time slot of the network node falls into the beacon time slot of the non-distribution network, adopting an HRF link to transmit a beacon frame; or performing HPLC channel detection if the beacon slot of the network node does not fall into the beacon slot of the non-distribution network, and performing the following operations according to the channel detection result: transmitting a beacon frame by adopting both an HPLC link and an HRF link under the condition that an HPLC channel is idle; or in case the HPLC channel is not idle, the beacon frame is sent using the HRF link.

Specifically, as shown in fig. 2, if the beacon slots of PCO1 and PCO2 fall within the beacon slot of the marketing network, the beacon frame is transmitted by using the HRF link as a communication scheme. If the beacon time slots of the PCO3, the PCO4 and the STA 1-STA 4 do not fall in the beacon time slot of the marketing network, carrying out channel detection on the HPLC link, and determining whether to transmit the beacon frame in a wireless or dual-mode communication mode according to the detection result. If the channel is idle (e.g., CSMA-CA time slots in fig. 2 are idle), then the beacon frame may be sent on the HPLC link, that is, both HPLC and HRF links may be used to send the beacon frame; otherwise, only one communication mode, i.e. an HRF link, can be used to transmit the beacon frame.

Before the node to be network-connected is updated to the network-connected node (i.e., step S101), the cooperative communication method may further include: initiating an association request comprising the candidate PCO on the HPLC link and the candidate PCO on the HRF link of the node to be network-connected to the CCO, so that the candidate PCO on the HPLC link or the candidate PCO on the HRF link is associated as the PCO of the node to be network-connected by the CCO according to whether the beacon time slots of the power distribution network and the non-power distribution network have conflict.

Specifically, before the networking process of the network access node is completed, the role of the network access node is to be the network access node. For the nodes to be network-connected, STAs on the optimal paths are selected as candidate PCOs on the HPLC link and the HRF link, respectively (a selection procedure/proxy evaluation procedure will be described in detail later). After the network node to be network-accessed determines candidate PCOs on two links, the network node to be network-accessed sends an association request, wherein the association request comprises the candidate PCOs on an HPLC link and the candidate PCOs on an HRF link of the network node to be network-accessed. At this time, the PCO or the network STA takes charge of forwarding the association request, and forwards the association request upwards to its CCO or proxy. After receiving the association request, the CCO performs a network access decision according to a certain criterion (for example, the candidate PCO on the HPLC link or the candidate PCO on the HRF link is associated to the PCO of the node to be accessed according to whether there is a conflict between the beacon slots of the power distribution network and the non-power distribution network, the specific decision process is described in the following about the content of the CCO), and constructs an association confirmation message, where the association confirmation message indicates that the node to be accessed is accessed to the network by the HPLC link or the HRF link.

Each node (including both the node to be network-connected and the node to be network-connected) maintains a local neighbor list. Under hybrid networking, the beacons received by the nodes to be networked are from either the HRF link or the HPLC link. After receiving the beacon, the network node to be accessed updates a neighbor list according to the site capability entry in the beacon, wherein the neighbor list records TEI, PCO of the neighbor node, the number of layers in the network, the role, the channel quality and the link type information. The node to be network-entered will perform a proxy evaluation described below after a period of beacon acquisition.

In an embodiment, the candidate PCOs on the HRF link of the node to be network-connected are obtained by: judging whether a first candidate network access node exists in a first neighbor list, wherein the first neighbor list is a neighbor list on an HRF link of the network access node to be accessed, and the channel quality of the first candidate network access node is larger than a first preset value; and determining one of the first candidate network access nodes as a candidate PCO on the HRF link according to a first preset evaluation rule in the case that the first candidate network access node exists in the first neighbor list, or determining a node with the largest number of received beacons in the network access node of the minimum hierarchy in the first neighbor list as a candidate PCO on the HRF link in the case that the first candidate network access node does not exist in the first neighbor list.

Wherein the determining one of the first candidate network access nodes as a candidate PCO on the HRF link according to a first preset evaluation rule comprises: determining a number of network access nodes of a minimum hierarchy of the first candidate network access nodes; according to the minimum number of network access nodes, the following operations are performed.

In particular, the operations may include: determining a minimum level of network access nodes on the HRF link as candidate PCOs on the HRF link if the number is one; or if the number is a plurality, judging whether PCO exists in the network access node of the minimum level on the HRF link, and executing the following operations: and if PCO exists, determining the PCO with the best channel quality in the network access node of the minimum level on the HRF link as the candidate PCO on the HRF link, or if PCO does not exist, determining the STA with the best channel quality in the network access node of the minimum level on the HRF link as the candidate PCO on the HRF link.

In step S310, the network node having the largest number of received beacons is selected as the candidate PCO.

In another embodiment, the candidate PCOs on the HPLC link of the node to be networked are obtained by: judging whether a second candidate network access node exists in a second neighbor list, wherein the second neighbor list is a neighbor list on an HPLC link of the node to be network accessed, and the channel quality of the second candidate network access node is larger than a second preset value; and determining one of the second candidate network access nodes as the candidate PCO on the HPLC link according to a second preset evaluation rule when the second candidate network access node exists in the second neighbor list, or not selecting any network access node as the candidate PCO on the HPLC link when the second candidate network access node does not exist in the second neighbor list.

And selecting candidate agent stations from the HPLC link, finding stations with channel quality greater than a threshold, selecting the stations with the lowest level as candidate agents, selecting the stations with the highest channel quality from the stations with PCO as roles if the stations with the lowest level are multiple, selecting the stations with the highest channel quality from the stations with the PCO as roles if the roles are all STA, and selecting the stations with the highest channel quality if the stations with the highest channel quality are not selected from the stations with the lowest channel quality.

In the various embodiments described above, the network node transmits beacon frames on the HRF link or on the HPLC link and HRF link under CCO schedule.

In summary, the present invention creatively responds to the CCO to update a node to be networked to the node to be networked of a power distribution network, and detects whether there is a conflict between beacon slots of the power distribution network and non-power distribution network; then, under the condition that the beacon time slots of the power distribution network and the non-power distribution network have conflict, judging whether the beacon time slot of the network access node falls into the beacon time slot of the non-power distribution network or not; finally, according to the judging result, the HRF link or both the HPLC link and the HRF link are adopted to send the beacon frame, so that the network access node can realize cooperative communication between the marketing network and the two networks of the power distribution network, and the frequency division frequency band of the HPLC communication is not required to be additionally customized, and the beacon time slot bandwidth is not required to be coordinated with the marketing network.

Fig. 5 is a flowchart of a cooperative communication method according to an embodiment of the present invention. The collaborative communication method is applied to CCO. As shown in fig. 5, the cooperative communication method may include: step S501, updating the node to be accessed to the network as the node accessing to the communication network; step S502, detecting whether there is a conflict between beacon slots of the power distribution network and the non-power distribution network; step S503, in case of conflict between the power distribution network and the non-power distribution network, adopting HRF link to transmit beacon frame; or in the case that there is no conflict between the beacon time slots of the power distribution network and the non-power distribution network, adopting both an HPLC link and an HRF link to send beacon frames.

Specifically, the CCO updates the node to be network-connected to the network-connected node (the specific update procedure will be described in detail in the following embodiments), which indicates that the networking procedure of the node to be network-connected is completed, and the node to be network-connected is converted into the network-connected node. Thereafter, it may be detected whether there is a collision of beacon slots of the distribution network with the non-distribution network by means of an inter-network coordination frame or any existing manner.

As shown in fig. 2, if there is a conflict between the power distribution network in the same area and the beacon slot of the marketing network, in this case, only one communication mode of the HRF link is adopted to send the beacon frame; and if the beacon time slots of the distribution network and the marketing network do not have conflict, adopting an HPLC link and an HRF link to transmit a beacon frame.

In an embodiment, the cooperative communication method may further include: detecting whether a conflict exists between the beacon time slots of the power distribution network and the non-power distribution network or not in response to an association request initiated by a node to be network-accessed, wherein the association request comprises candidate PCOs on an HPLC (high performance liquid chromatography) link of the node to be network-accessed and candidate PCOs on an HRF (high performance liquid chromatography) link; and according to a conflict detection result, associating the candidate PCO on the HPLC link or the candidate PCO on the HRF link as the PCO of the node to be network-connected so as to update the node to be network-connected as the network-connected node.

Wherein the associating the candidate PCO on the HPLC link or the candidate PCO on the HRF link as the PCO of the node to be networked comprises: under the condition that the beacon time slots of the power distribution network and the non-power distribution network collide, selecting the candidate PCO on the HRF link as the PCO of the node to be network-accessed; or if there is no conflict between the beacon time slots of the power distribution network and the non-power distribution network, judging whether the levels of the candidate PCOs on the HPLC link and the candidate PCOs on the HRF link are the same, and executing the following operations.

In particular, the operations may include: determining PCO with better channel quality in the candidate PCO on the HPLC link and the candidate PCO on the HRF link as PCO of the node to be network-accessed under the condition that the levels of the candidate PCO on the HPLC link and the candidate PCO on the HRF link are the same; or in the case that the levels of the candidate PCOs on the HPLC link and the candidate PCOs on the HRF link are different, determining the PCO with the smaller level of the candidate PCOs on the HPLC link and the candidate PCOs on the HRF link as the PCO of the node to be network-connected.

After receiving the message of the association request of the node to be accessed to the network, the CCO will make the access judgment.

As shown in fig. 6, the CCO' S network access decision may include steps S601-S605.

Step S601, judging whether beacon time slots of the distribution network and the marketing network conflict, if so, executing step S602; otherwise, step S603 is performed.

And when the agent selection is carried out, judging whether the beacon time slot of the marketing network conflicts or not according to the inter-network coordination frame.

Step S602, selecting a candidate PCO on the HRF link as PCO.

Step S603, judging whether the levels of the candidate PCOs on the HPLC link and the HRF link are the same, if yes, executing step S604; otherwise, step S605 is executed.

In step S604, a candidate PCO with better channel quality is selected as the PCO.

In step S605, a candidate PCO having a smaller hierarchy is selected as the PCO.

If the channel quality is not in conflict, selecting a small-level agent from the HPLC and the HRF candidate agents as a final agent, if the levels are the same, selecting a good channel quality as the final agent, otherwise, preferentially selecting the HRF link to access the network.

If the node to be network-accessed is allowed to access the network, the TEI is allocated to the node to be network-accessed, a global topology table and a routing table are updated, and an association confirmation message is constructed, wherein the node to be network-accessed is indicated to be network-accessed by an HPLC link or an HRF link in the association confirmation message. The connection mode (HPLC link or HRF link access) of the node to be accessed to the network and the PCO of the upper stage is the network access mode, and the node to be accessed to the network is the main route. And the beacon frame is a broadcast frame that may be transmitted on both the HPLC link and the HRF link.

In summary, the present invention creatively updates the node to be network-connected to the network-connected node of the communication network; then, detecting whether the beacon time slots of the power distribution network and the non-power distribution network have conflicts or not; finally, under the condition that the beacon time slots of the power distribution network and the non-power distribution network collide, a HRF link is adopted to transmit a beacon frame; or in the case that there is no conflict between the beacon time slots of the power distribution network and the non-power distribution network, adopting both an HPLC link and an HRF link to send beacon frames. Therefore, the invention can realize cooperative communication between the marketing network and the two networks of the distribution network by the CCO without additionally customizing the frequency division frequency band of the HPLC communication and coordinating the beacon time slot bandwidth with the marketing network.

In the above embodiments, the distribution network and the non-distribution network (e.g., marketing network) are located in the same area, the non-distribution network (e.g., marketing network) mainly adopts HPLC as a local access scheme, and the distribution network adopts HPLC and HRF (broadband micro power radio) converged networking as a local communication access scheme. The broadband micropower wireless is 40M bandwidth of 470M-510M, the working bandwidth is 4M, 2M, 1M and 500K, and the highest information rate can reach 1.6MHz.

In the various embodiments described above, a "node" may be interchanged with a "site". For a node to be network-connected, it may be a STA to be network-connected; for an access node, it may be an access STA or PCO, which is a STA of a special role.

Under the dual-mode fusion networking, the CCO transmits beacon frames on both the HRF link and the HPLC link, but does not transmit beacon frames on the HPLC link when the power distribution network collides with the marketing network. When the power distribution network collides with the marketing network, if the beacon time slot of the PCO/STA is in the beacon time slot of the marketing network, a beacon frame is sent on the HRF link; otherwise, the PCO and STA perform HPLC channel sounding before sending the beacon frame: if the HPLC channel is idle, beacon frames are sent out on the HPLC link and on the HRF link, and if the HPLC channel is not idle, only beacon frames are sent out on the HRF link. And selecting a transmission link according to the service type.
