本发明涉及通信领域，具体地涉及一种协同通信方法与系统、入网节点、CCO、存储介质以及芯片。The present invention relates to the field of communications, and in particular to a collaborative communication method and system, a network access node, a CCO, a storage medium and a chip.

背景技术Background technique

配电物联网涉及“云管边端”技术架构，其中“管”层作为配电物联网“云、边、端”的数据传输通道，承载着配电物联网各类业务，其是配电物联网建设中的重要内容。“管”层采用“远程通信网+本地通信网”的技术架构。The power distribution Internet of Things involves the "cloud, pipe, edge, and end" technical architecture, in which the "pipe" layer serves as the data transmission channel for the "cloud, edge, and end" of the power distribution Internet of Things, carrying various services of the power distribution Internet of Things. It is an important part of the construction of the power distribution Internet of Things. The "pipe" layer adopts the technical architecture of "remote communication network + local communication network".

远程通信接入网指末端业务终端(如传感器、表计、DTU、电动汽车充电桩等)或边缘汇聚终端(如集中器、边缘物联代理装置、输电线路状态监测代理等)直接与骨干通信网连接的通信接入网络。远程通信接入网主要采用光纤通信、无线公网通信、无线专网通信等，主要满足配电云平台与边缘计算终端之间高可靠、低时延、差异化的通信需求。而本地通信接入网指末端业务终端与边缘汇聚终端连接的通信接入网络。本地通信接入网主要采用低压电力线载波、微功率无线通信、本地以太网、串行通信等，满足边缘计算终端与低压智能设备之间的业务数据可靠传输通信需求。The remote communication access network refers to the communication access network that directly connects the end business terminal (such as sensors, meters, DTU, electric vehicle charging piles, etc.) or the edge aggregation terminal (such as concentrators, edge IoT agent devices, transmission line status monitoring agents, etc.) to the backbone communication network. The remote communication access network mainly adopts optical fiber communication, wireless public network communication, wireless private network communication, etc., and mainly meets the high reliability, low latency and differentiated communication requirements between the distribution cloud platform and the edge computing terminal. The local communication access network refers to the communication access network that connects the end business terminal to the edge aggregation terminal. The local communication access network mainly adopts low-voltage power line carrier, micro-power wireless communication, local Ethernet, serial communication, etc., to meet the reliable transmission and communication requirements of business data between edge computing terminals and low-voltage smart devices.

随着配电物联网建设的推进，融合终端建设已初具规模，云平台也已实现基本功能，低压设备也已形成产品。但本地通信方面目前还没有完善的解决方案，已成为制约配电物联网发展的因素。With the advancement of the construction of the power distribution Internet of Things, the construction of integrated terminals has begun to take shape, the cloud platform has also realized basic functions, and low-voltage equipment has also become a product. However, there is currently no perfect solution for local communications, which has become a factor restricting the development of the power distribution Internet of Things.

目前，营销网络已有的本地通信技术主要包括高速电力线载波（HPLC）通信、微功率无线(RF X470 MHz) Wi-SUN RF (920 MHz )通信、HPLC+RF双模通信等通信方式。配电网的本地通信方式在目前没有指定统一标准的情况下，可以采用营销网络的本地通信技术方案。营销网络大量部署HPLC网络，配电网络与营销网络共存一般采用分频或同频的方式。At present, the local communication technologies available in 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 methods. In the absence of a unified standard for the local communication method of the distribution network, the local communication technology solution of the marketing network can be adopted. The marketing network deploys a large number of HPLC networks, and the coexistence of the distribution network and the marketing network generally adopts the method of frequency division or frequency coexistence.

HPLC通信的工作频率范围包含4个频段：频段0：2MHz～12MHz、频段1：2.4MHz～5.6MHz、频段2：0.7MHz～3MHz、频段3：1.7MHz～3MHz，能够提供数百kbps至几Mbps的数据传输速率，并且电力线在高频段的噪声相对较弱，相对于窄带电力线通信，通信可靠性和稳定性显著提升。在实际应用现场，主要使用频段2；而对噪声干扰大的台区，切换至频段1使用。这四个频段互相有重叠的部分，配电网若用频段1进行大规模使用，高频段衰减较大，不能适用于所有台区；两个频段在同一线路同时工作，带外泄露会相互影响，对于现场个别噪声大的台区，会形成带内干扰。配电网络可能需要根据扩展频段进行定制。The operating frequency range of HPLC communication includes 4 frequency bands: Band 0: 2MHz~12MHz, Band 1: 2.4MHz~5.6MHz, Band 2: 0.7MHz~3MHz, Band 3: 1.7MHz~3MHz, which can provide data transmission rates from hundreds of kbps to several Mbps, and the noise of power lines in high frequency bands is relatively weak. Compared with narrowband power line communication, the communication reliability and stability are significantly improved. In actual application sites, Band 2 is mainly used; and for areas with large noise interference, it is switched to Band 1. These four frequency bands overlap with each other. If the distribution network uses Band 1 on a large scale, the high frequency band will be attenuated greatly and cannot be applied to all areas; if the two frequency bands work on the same line at the same time, the out-of-band leakage will affect each other, and for individual areas with large noise on site, in-band interference will be formed. The distribution network may need to be customized according to the extended frequency band.

配电网络与营销网络同频时，现有载波协议规定了多子网带宽协调机制来实现各子网信标时隙区在时间轴上的交错，但相关研究表明，受到多跳网络典型的‘隐藏终端’问题的影响，该机制虽然可以解决不同子网信标信号之间的干扰，但无法有效解决一个子网信标信号传输过程受到其它子网非信标信号的干扰问题，在网络业务负荷较大的情况下将极大影响信标信号的传输效果。配电和营销大量设备相互交错，使得网间协调较为复杂，并且营销网络未必同意主动避让配电网络。When the distribution network and the marketing network are on the same frequency, the existing carrier protocol stipulates a multi-subnet bandwidth coordination mechanism to achieve the interleaving of the beacon time slots of each subnet on the time axis. However, relevant studies have shown that, affected by the typical "hidden terminal" problem of multi-hop networks, although this mechanism can solve the interference between beacon signals of different subnets, it cannot effectively solve the problem that the transmission process of a subnet beacon signal is interfered by non-beacon signals of other subnets. Under the condition of heavy network business load, it will greatly affect the transmission effect of beacon signals. A large number of distribution and marketing equipment are intertwined, making inter-network coordination more complicated, and the marketing network may not agree to actively avoid the distribution network.

It should be understood that the specific implementation described herein is only used to illustrate and explain the present invention, and is not used to limit the present invention.

在介绍本发明的各个实施例之前，先对本发明中的几个英文缩写进行解释。HPLC：高速电力线载波通信；HRF：高速无线通信；CCO：中央协调器；STA：站；PCO：代理节点（PCO还可以与其它PCO或STA连接，而STA是末级节点，不再与其它节点相连）；TEI：源终端设备标识；CSMA-CA：带有冲突避免的载波侦听多路访问。Before introducing the various embodiments of the present invention, several English abbreviations in the present invention are explained first. HPLC: high-speed power line carrier communication; HRF: high-speed wireless communication; CCO: central coordinator; STA: station; PCO: proxy node (PCO can also be connected to other PCOs or STAs, while STA is a terminal node and is no longer connected to other nodes); TEI: source terminal equipment identification; CSMA-CA: carrier sense multiple access with collision avoidance.

图1是本发明一实施例提供的协同通信方法的流程图。所述协同通信方法应用于入网节点。如图1所示，所述协同通信方法可包括：步骤S101，响应于CCO将待入网节点更新为配电网的所述入网节点，检测所述配电网与非配电网的信标时隙是否存在冲突；步骤S102，在所述配电网与所述非配电网的信标时隙存在冲突的情况下，判断所述入网节点的信标时隙是否落入所述非配电网的信标时隙；以及步骤S103，根据判断结果，采用HRF链路或者采用HPLC链路与HRF链路两者发送信标帧。FIG1 is a flow chart of a collaborative communication method provided by an embodiment of the present invention. The collaborative communication method is applied to a network access node. As shown in FIG1 , the collaborative communication method may include: step S101, in response to CCO updating the node to be networked to the network access node of the distribution network, detecting whether there is a conflict between the beacon time slots of the distribution network and the non-distribution network; step S102, in the case where there is a conflict between the beacon time slots of the distribution network and the non-distribution network, judging whether the beacon time slot of the network access node falls into the beacon time slot of the non-distribution network; and step S103, according to the judgment result, using HRF link or using both HPLC link and HRF link to send beacon frames.

其中，所述非配电网可为使用HPLC通信与RF通信作为本地通信的任何非配电网络。例如，所述非配电网可为营销网。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.

下面分别针对上述步骤S101-S103的具体内容进行解释和说明。The specific contents of the above steps S101 to S103 are explained and illustrated below.

步骤S101，响应于CCO将待入网节点更新为配电网的所述入网节点，检测所述配电网与非配电网的信标时隙是否存在冲突。Step S101, in response to the CCO updating the node to be connected to the connected node of the distribution network, detecting whether there is a conflict between the beacon time slots of the distribution network and the non-distribution network.

其中，所述入网节点为PCO（例如，PCO1、PCO2、PCO3、PCO4）或STA（例如，STA1、STA2、STA3、STA4）。The network access node is a PCO (for example, PCO1, PCO2, PCO3, PCO4) or a STA (for example, STA1, STA2, STA3, STA4).

若CCO将待入网节点更新为入网节点，表明待入网节点的组网过程完成，所述待入网节点的角色转化为入网节点。之后，可通过网间协调帧或者现有的任何方式检测配电网与非配电网的信标时隙是否存在冲突。If the CCO updates the node to be networked to the node to be networked, it indicates that the networking process of the node to be networked is completed, and the role of the node to be networked is converted to the node to be networked. Afterwards, the beacon time slots of the distribution network and the non-distribution network can be detected by using the inter-network coordination frame or any existing method to determine whether there is a conflict.

步骤S102，在所述配电网与所述非配电网的信标时隙存在冲突的情况下，判断所述入网节点的信标时隙是否落入所述非配电网的信标时隙。Step S102, when there is a conflict between the beacon time slots of the distribution network and the non-distribution network, it is determined whether the beacon time slot of the network access node falls into the beacon time slot of the non-distribution network.

如图2所示，同一台区中的配电网与营销网的信标时隙存在冲突，在此情况下，继续判断入网节点的信标时隙是否落入营销网的信标时隙：例如，PCO1、PCO2的信标时隙完全落在营销网的信标时隙内；PCO3、PCO4、STA1~STA4的信标时隙落在营销网的CSMA-CA时隙内，其未落在营销网的信标时隙内。As shown in Figure 2, there is a conflict between the beacon time slots of the distribution network and the marketing network in the same substation. In this case, continue to judge whether the beacon time slot of the access node falls into the beacon time slot of the marketing network: for example, the beacon time slots of PCO1 and PCO2 completely fall within the beacon time slot of the marketing network; the beacon time slots of PCO3, PCO4, STA1~STA4 fall within the CSMA-CA time slot of the marketing network, and they do not fall within the beacon time slot of the marketing network.

在一实施例中，所述协同通信方法还可包括：在所述配电网与所述非配电网的信标时隙不存在冲突的情况下，采用HPLC链路与HRF链路两者发送信标帧。In one embodiment, the cooperative communication method may further include: when there is no conflict between the beacon time slots of the distribution network and the non-distribution network, using both the HPLC link and the HRF link to send the beacon frame.

例如，通过步骤S101的检测过程，若所述配电网与所述营销网的信标时隙不存在冲突，则采用HPLC链路与HRF链路两种通信方式发送信标帧。For example, through the detection process of step S101, if there is no conflict between the beacon time slots of the distribution network and the marketing network, the beacon frame is sent using two communication modes, HPLC link and HRF link.

步骤S103，根据判断结果，采用HRF链路或者采用HPLC链路与HRF链路两者发送信标帧。Step S103: Based on the judgment result, a beacon frame is sent using the HRF link or using both the HPLC link and the HRF link.

对于步骤S103，所述采用HRF链路或者采用HPLC链路与HRF链路两者发送信标帧可包括：在所述入网节点的信标时隙落入所述非配电网的信标时隙的情况下，采用HRF链路发送信标帧；或者在所述入网节点的信标时隙未落入所述非配电网的信标时隙的情况下，进行HPLC信道检测，以及根据信道检测结果执行以下操作：在HPLC信道处于空闲的情况下，采用HPLC链路与HRF链路两者发送信标帧；或者在HPLC信道处于非空闲的情况下，采用HRF链路发送信标帧。For step S103, the use of the HRF link or the use of both the HPLC link and the HRF link to send beacon frames may include: when the beacon time slot of the network access node falls into the beacon time slot of the non-distribution network, using the HRF link to send beacon frames; or when the beacon time slot of the network access node does not fall into the beacon time slot of the non-distribution network, performing HPLC channel detection, and performing the following operations according to the channel detection results: when the HPLC channel is idle, using both the HPLC link and the HRF link to send beacon frames; or when the HPLC channel is not idle, using the HRF link to send beacon frames.

具体地，如图2所示，若PCO1、PCO2的信标时隙落在营销网的信标时隙内，则采用HRF链路这一种通信方式发送信标帧。若PCO3、PCO4、STA1~STA4的信标时隙未落在营销网的信标时隙内，则针对HPLC链路进行信道检测，并根据检测结果决定采用无线通过还是双模通信方式发送信标帧。若信道空闲（例如，图2中的CSMA-CA时隙空闲），则可以在HPLC链路上发送信标帧，也就是说，可以采用HPLC链路与HRF链路两种通信方式发送信标帧；否则，只能采用HRF链路这一种通信方式发送信标帧。Specifically, as shown in FIG2 , if the beacon time slots of PCO1 and PCO2 fall within the beacon time slots of the marketing network, the HRF link is used as a communication mode to send the beacon frame. If the beacon time slots of PCO3, PCO4, and STA1~STA4 do not fall within the beacon time slots of the marketing network, a channel detection is performed on the HPLC link, and the wireless or dual-mode communication mode is used to send the beacon frame based on the detection result. If the channel is idle (for example, the CSMA-CA time slot in FIG2 is idle), the beacon frame can be sent on the HPLC link, that is, the HPLC link and the HRF link can be used to send the beacon frame; otherwise, the HRF link can only be used as a communication mode to send the beacon frame.

在所述待入网节点被更新为所述入网节点（即步骤S101）之前，所述协同通信方法还可包括：向CCO发起包括所述待入网节点的HPLC链路上的候选PCO以及HRF链路上的候选PCO的关联请求，以由所述CCO根据所述配电网与所述非配电网的信标时隙是否存在冲突将所述HPLC链路上的候选PCO或者所述HRF链路上的候选PCO关联为所述待入网节点的PCO。Before the node to be networked is updated to the networked node (i.e., step S101), the collaborative communication method may further include: initiating an association request including a candidate PCO on the HPLC link and a candidate PCO on the HRF link of the node to be networked to the CCO, so that the CCO associates the candidate PCO on the HPLC link or the candidate PCO on the HRF link as the PCO of the node to be networked according to whether there is a conflict between the beacon time slots of the distribution network and the non-distribution network.

具体地，所述入网节点的组网过程完成之前，其角色为待入网节点。对于所述待入网节点而言，分别在HPLC链路与HRF链路上选择最优路径上的STA作为候选PCO（将于下文说明书具体的选择过程/代理评估过程）。在待入网节点确定好两条链路上的候选PCO之后，所述待入网节点发送关联请求，其中，所述关联请求包括所述待入网节点的HPLC链路上的候选PCO以及HRF链路上的候选PCO。此时，PCO或入网STA负责所述关联请求的转发，向上转发给自己的CCO或代理。CCO收到所述关联请求后，会根据一定的准则进行入网判决（例如，根据所述配电网与所述非配电网的信标时隙是否存在冲突将所述HPLC链路上的候选PCO或者所述HRF链路上的候选PCO关联为所述待入网节点的PCO，具体判决过程详见下文中关于CCO的相关内容），并构造关联确认消息，在关联确认报文中指示所述待入网节点以HPLC链路或HRF链路入网。Specifically, before the networking process of the access node is completed, its role is a node to be networked. For the node to be networked, the STA on the optimal path is selected as a candidate PCO on the HPLC link and the HRF link respectively (the specific selection process/agent evaluation process will be described in the following specification). After the node to be networked determines the candidate PCOs on the two links, the node to be networked sends an association request, wherein the association request includes the candidate PCO on the HPLC link of the node to be networked and the candidate PCO on the HRF link. At this time, the PCO or the access STA is responsible for forwarding the association request, and forwards it upward to its own CCO or agent. After receiving the association request, the CCO will make a network access decision according to certain criteria (for example, according to whether there is a conflict between the beacon time slots of the distribution network and the non-distribution network, 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 networked, and the specific decision process is detailed in the following content about CCO), and construct an association confirmation message, and instruct the node to be networked to access the network with the HPLC link or the HRF link in the association confirmation message.

每个节点（包括待入网节点与入网节点）都会维护本地的邻居列表。混合组网下，待入网节点接收到的信标有来自HRF链路或HPLC链路的。待入网节点收到信标后，会根据信标中的站点能力条目更新邻居列表，其中所述邻居列表中记录的是邻居节点的TEI、PCO、网络中的层级数、角色、信道质量、链路类型信息。待入网节点会经过一段时间的信标采集时期后进行下文所述的代理评估。Each node (including nodes to be networked and nodes to be networked) maintains a local neighbor list. In a hybrid network, the beacons received by the nodes to be networked come from HRF links or HPLC links. After receiving the beacon, the node to be networked will update the neighbor list according to the site capability entry in the beacon, where the neighbor list records the TEI, PCO, number of layers in the network, role, channel quality, and link type information of the neighbor node. After a period of beacon collection, the node to be networked will perform the proxy evaluation described below.

在一实施例中，所述待入网节点的HRF链路上的候选PCO通过以下方式获取：判断第一邻居列表中是否存在第一候选入网节点，其中，所述第一邻居列表为所述待入网节点的HRF链路上的邻居列表，以及所述第一候选入网节点的信道质量大于第一预设值；以及在所述第一邻居列表中存在所述第一候选入网节点的情况下，按照第一预设评估规则将所述第一候选入网节点中的一者确定为所述HRF链路上的候选PCO，或者在所述第一邻居列表中不存在所述第一候选入网节点的情况下，将所述第一邻居列表中的最小层级的入网节点中的接收到的信标数目最多的节点确定为所述HRF链路上的候选PCO。In one embodiment, the candidate PCO on the HRF link of the node to be networked is obtained in the following manner: judging whether there is a first candidate networked node in a first neighbor list, wherein the first neighbor list is a neighbor list on the HRF link of the node to be networked, and a channel quality of the first candidate networked node is greater than a first preset value; and in a case where the first candidate networked node exists in the first neighbor list, determining one of the first candidate networked nodes as the candidate PCO on the HRF link according to a first preset evaluation rule, or in a case where the first candidate networked node does not exist in the first neighbor list, determining a node with the largest number of received beacons among the networked nodes at the smallest level in the first neighbor list as the candidate PCO on the HRF link.

上述两类实施例中的代理评估的算法是：从邻居列表中找到信道质量大于门限的站点，从中选择HRF链路中层级最低的站点作为候选代理，若层级最低的站点有多个，则选择角色为PCO的站点中信道质量最好的，若角色均为STA，则从中选择信道质量最好的。若还是没有选择到候选代理站点，则不考虑信道质量超过门限的限制，从邻居列表中选择HRF链路中层级最低的站点作为代理，若有多个，则选择接收到信标数目最多的。再从HPLC链路中筛选候选代理站点，找到信道质量大于门限的站点，从中选择层级最低的站点作为候选代理，若层级最低的站点有多个，则选择角色为PCO的站点中信道质量最好的，若角色均为STA，则从中选择信道质量最好的，若还是没有选择到候选代理站点，则HPLC链路上不选择候选代理。The proxy evaluation algorithm in the above two types of embodiments is: find a station with a channel quality greater than a threshold from the neighbor list, and select the station with the lowest level in the HRF link as a candidate proxy. If there are multiple stations with the lowest level, select the station with the best channel quality among the stations with the role of PCO. If all the roles are STA, select the station with the best channel quality. If the candidate proxy station is still not selected, the restriction that the channel quality exceeds the threshold is not considered, and the station with the lowest level in the HRF link is selected from the neighbor list as a proxy. If there are multiple stations, select the station with the largest number of beacons received. Then screen the candidate proxy stations from the HPLC link, find the station with a channel quality greater than the threshold, and select the station with the lowest level as a candidate proxy. If there are multiple stations with the lowest level, select the station with the best channel quality among the stations with the role of PCO. If all the roles are STA, select the station with the best channel quality. If the candidate proxy station is still not selected, no candidate proxy is selected on the HPLC link.

上述各个实施例中，所述入网节点是在CCO安排下在HRF链路或者在HPLC链路和HRF链路上发送信标帧。In the above-mentioned embodiments, the network-entering node sends a beacon frame on the HRF link or on the HPLC link and the HRF link under the arrangement of the CCO.

综上所述，本发明创造性地响应于CCO将待入网节点更新为配电网的所述入网节点，检测所述配电网与非配电网的信标时隙是否存在冲突；然后，在所述配电网与所述非配电网的信标时隙存在冲突的情况下，判断所述入网节点的信标时隙是否落入所述非配电网的信标时隙；最后，根据判断结果，采用HRF链路或者采用HPLC链路与HRF链路两者发送信标帧，由此，本发明可由入网节点实现营销网与配电网两个网络之间的协同通信，而不需要额外定制HPLC通信的分频频段，也不需要与营销网络协调信标时隙带宽。To summarize, the present invention creatively responds to CCO updating the node to be connected to the network as the network-connected node of the distribution network, and detects whether there is a conflict between the beacon time slots of the distribution network and the non-distribution network; then, when there is a conflict between the beacon time slots of the distribution network and the non-distribution network, it is determined whether the beacon time slot of the network-connected node falls into the beacon time slot of the non-distribution network; finally, according to the judgment result, the beacon frame is sent using the HRF link or both the HPLC link and the HRF link. Therefore, the present invention can realize the coordinated communication between the marketing network and the distribution network by the network-connected node, without the need to additionally customize the frequency division band of the HPLC communication, and without the need to coordinate the beacon time slot bandwidth with the marketing network.

图5是本发明一实施例提供的协同通信方法的流程图。所述协同通信方法应用于CCO。如图5所示，所述协同通信方法可包括：步骤S501，将待入网节点更新为通信网络的入网节点；步骤S502，检测所述配电网与非配电网的信标时隙是否存在冲突；以及步骤S503，在所述配电网与所述非配电网的信标时隙存在冲突的情况下，采用HRF链路发送信标帧；或者在所述配电网与所述非配电网的信标时隙不存在冲突的情况下，采用HPLC链路与HRF链路两者发送信标帧。FIG5 is a flow chart of a collaborative communication method provided by an embodiment of the present invention. The collaborative communication method is applied to CCO. As shown in FIG5, the collaborative communication method may include: step S501, updating the node to be connected to the network to be a node connected to the network of the communication network; step S502, detecting whether there is a conflict between the beacon time slots of the distribution network and the non-distribution network; and step S503, in the case where there is a conflict between the beacon time slots of the distribution network and the non-distribution network, using the HRF link to send the beacon frame; or in the case where there is no conflict between the beacon time slots of the distribution network and the non-distribution network, using both the HPLC link and the HRF link to send the beacon frame.

其中，所述非配电网可为使用HPLC通信与RF通信作为本地通信的任何非配电网络。例如，所述非配电网可为营销网。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.

具体地，CCO将待入网节点更新为入网节点（具体更新过程可详见下个实施例的说明），表明待入网节点的组网过程完成，所述待入网节点转化为入网节点。之后，可通过网间协调帧或者现有的任何方式检测配电网与非配电网的信标时隙是否存在冲突。Specifically, the CCO updates the node to be networked to the node to be networked (the specific update process can be seen in the description of the next embodiment), indicating that the networking process of the node to be networked is completed, and the node to be networked is converted into the node to be networked. Afterwards, the beacon time slots of the distribution network and the non-distribution network can be detected by the inter-network coordination frame or any existing method to see if there is a conflict.

如图2所示，若同一台区中的配电网与营销网的信标时隙存在冲突，在此情况下，仅采用HRF链路一种通信方式发送信标帧；若所述配电网与所述营销网的信标时隙不存在冲突的情况下，采用HPLC链路与HRF链路两种通信方式发送信标帧。As shown in Figure 2, if there is a conflict in the beacon time slots of the distribution network and the marketing network in the same substation, in this case, only the HRF link is used as a communication method to send beacon frames; if there is no conflict in the beacon time slots of the distribution network and the marketing network, both the HPLC link and the HRF link are used to send beacon frames.

在一实施例中，所述协同通信方法还可包括：响应于待入网节点发起的关联请求，检测所述配电网与所述非配电网的信标时隙是否存在冲突，其中，所述关联请求包括所述待入网节点的HPLC链路上的候选PCO以及HRF链路上的候选PCO；以及根据冲突检测结果，将所述HPLC链路上的候选PCO或者所述HRF链路上的候选PCO关联为所述待入网节点的PCO，以更新所述待入网节点为所述入网节点。In one embodiment, the collaborative communication method may further include: in response to an association request initiated by the node to be connected, detecting whether there is a conflict between the beacon time slots of the distribution network and the non-distribution network, wherein the association request includes the candidate PCO on the HPLC link of the node to be connected and the candidate PCO on the HRF link; and based on the 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 connected, so as to update the node to be connected to the node to be connected.

其中，所述将所述HPLC链路上的候选PCO或者所述HRF链路上的候选PCO关联为所述待入网节点的PCO包括：在所述配电网与所述非配电网的信标时隙存在冲突的情况下，选择所述HRF链路上的候选PCO作为所述待入网节点的PCO；或者在所述配电网与所述非配电网的信标时隙不存在冲突的情况下，判断所述HPLC链路上的候选PCO与HRF链路上的候选PCO的层级是否相同，并执行以下操作。Among them, associating the candidate PCO on the HPLC link or the candidate PCO on the HRF link as the PCO of the node to be connected to the network includes: when there is a conflict between the beacon time slots of the distribution network and the non-distribution network, selecting the candidate PCO on the HRF link as the PCO of the node to be connected to the network; or when there is no conflict between the beacon time slots of the distribution network and the non-distribution network, judging whether the candidate PCO on the HPLC link and the candidate PCO on the HRF link have the same level, and performing the following operations.

具体地，所述操作可包括：在所述HPLC链路上的候选PCO与所述HRF链路上的候选PCO的层级相同的情况下，将所述HPLC链路上的候选PCO与所述HRF链路上的候选PCO中的信道质量更好的PCO确定为所述待入网节点的PCO；或者在HPLC链路上的候选PCO与HRF链路上的候选PCO的层级不同的情况下，将所述HPLC链路上的候选PCO与所述HRF链路上的候选PCO中的层级更小的PCO确定为所述待入网节点的PCO。Specifically, the operation may include: when the candidate PCO on the HPLC link and the candidate PCO on the HRF link have the same level, determining the PCO with better channel quality between the candidate PCO on the HPLC link and the candidate PCO on the HRF link as the PCO of the node to be connected to the network; or when the candidate PCO on the HPLC link and the candidate PCO on the HRF link have different levels, determining the PCO with a smaller level between the candidate PCO on the HPLC link and the candidate PCO on the HRF link as the PCO of the node to be connected to the network.

CCO收到待入网节点的关联请求的消息后，将进行入网判决。After receiving the association request message from the node to be admitted to the network, CCO will make a network admission decision.

如图6所示，CCO的入网判决可包括步骤S601-S605。As shown in FIG. 6 , the network access decision of the CCO may include steps S601 - S605 .

步骤S601，判断配电网与营销网的信标时隙是否冲突，若是，则执行步骤S602；否则，执行步骤S603。Step S601, determine whether the beacon time slots of the distribution network and the marketing network conflict, if so, execute step S602; otherwise, execute step S603.

在进行代理选择时，根据网间协调帧判断与营销网信标时隙是否冲突。When selecting an agent, determine whether there is a conflict with the marketing network beacon time slot based on the inter-network coordination frame.

步骤S602，选择HRF链路上的候选PCO作为PCO。Step S602: Select a candidate PCO on the HRF link as the PCO.

步骤S603，判断HPLC链路与HRF链路上的候选PCO的层级是否相同，若是，则执行步骤S604；否则，执行步骤S605。Step S603, determining whether the levels of the candidate PCOs on the HPLC link and the HRF link are the same, if so, executing step S604; otherwise, executing step S605.

步骤S604，选择信道质量更好的候选PCO作为PCO。Step S604: Select a candidate PCO with better channel quality as the PCO.

步骤S605，选择层级更小的候选PCO作为PCO。Step S605: Select a candidate PCO with a smaller level as the PCO.

若不冲突则从HPLC和HRF候选代理中选择层级小的作为最终代理，若层级相同，则选择信道质量较好的作为最终代理，否则优先选择HRF链路入网。If there is no conflict, the candidate agent with a smaller level is selected from the HPLC and HRF as the final agent. If the levels are the same, the agent with better channel quality is selected as the final agent. Otherwise, the HRF link is given priority to access the network.

如果允许待入网节点接入网络，则向其分配TEI，并更新全局的拓扑表、路由表，并构造关联确认消息，在关联确认报文中指示待入网节点以HPLC链路或HRF链路入网。待入网节点与其上一级PCO的连接方式（HPLC链路或HRF链路入网）即为入网方式，为其主路由。而信标帧是广播帧，其可以在HPLC链路与HRF链路两条链路上发送。If the node to be connected is allowed to access the network, TEI is assigned to it, the global topology table and routing table are updated, and an association confirmation message is constructed, indicating that the node to be connected is connected to the network via HPLC link or HRF link. The connection mode between the node to be connected and its upper-level PCO (HPLC link or HRF link access) is the access mode, which is its main route. The beacon frame is a broadcast frame, which can be sent on both the HPLC link and the HRF link.

综上所述，本发明创造性地首先将待入网节点更新为通信网络的入网节点；然后，检测所述配电网与非配电网的信标时隙是否存在冲突；最后，在所述配电网与所述非配电网的信标时隙存在冲突的情况下，采用HRF链路发送信标帧；或者在所述配电网与所述非配电网的信标时隙不存在冲突的情况下，采用HPLC链路与HRF链路两者发送信标帧。由此，本发明可由CCO实现营销网与配电网两个网络之间的协同通信，而不需要额外定制HPLC通信的分频频段，也不需要与营销网络协调信标时隙带宽。In summary, the present invention creatively updates the node to be connected to the network to be the node connected to the communication network first; then, detects whether there is a conflict between the beacon time slots of the distribution network and the non-distribution network; finally, when there is a conflict between the beacon time slots of the distribution network and the non-distribution network, the HRF link is used to send the beacon frame; or when there is no conflict between the beacon time slots of the distribution network and the non-distribution network, the HPLC link and the HRF link are used to send the beacon frame. Therefore, the present invention can realize the coordinated communication between the marketing network and the distribution network by CCO, without the need to customize the frequency division band of the HPLC communication, and without coordinating the beacon time slot bandwidth with the marketing network.

在上述各个实施例中，配电网与非配电网（例如，营销网）处于同一台区，非配电网（例如，营销网）主要采用HPLC为本地接入方案，并且配电网络采用HPLC与HRF（宽带微功率无线）融合组网为本地通信接入方案。宽带微功率无线为470M~510M的40M带宽，工作带宽有4M、2M、1M、500K，最高信息速率可以达到1.6MHz。In the above embodiments, the distribution network and the non-distribution network (for example, the marketing network) are in the same substation, the non-distribution network (for example, the marketing network) mainly adopts HPLC as the local access solution, and the distribution network adopts HPLC and HRF (broadband micro-power wireless) fusion networking as the local communication access solution. Broadband micro-power wireless has a 40M bandwidth of 470M~510M, and the working bandwidth is 4M, 2M, 1M, 500K, and the maximum information rate can reach 1.6MHz.

在上述各个实施例中，“节点”可与“站点”进行互换。对于待入网节点，其可为待入网STA；对于入网节点，其可为入网STA或PCO，PCO是特殊角色的STA。In the above embodiments, "node" and "station" can be interchanged. For a node to be added to the network, it can be a STA to be added to the network; for a node to be added to the network, it can be a STA to be added to the network or a PCO, and a PCO is a STA with a special role.

双模融合组网下，CCO在HRF链路与HPLC链路上均要发送信标帧，但当配电网与营销网存在冲突时，CCO 在HPLC链路不发信标帧。当配电网与营销网存在冲突时，若PCO/STA的信标时隙落在营销网的信标时隙，则在HRF链路上发信标帧；否则，PCO与STA在发送信标帧之前先进行HPLC信道探测：若HPLC信道空闲，则HPLC链路上和HRF链路上均发信标帧，若HPLC信道不空闲，则只在HRF链路上发信标帧。根据业务类型选择发送链路。此种方案不需要额外定制HPLC分频频段，也不需要与营销网络协调信标时隙带宽。In dual-mode fusion networking, CCO must send beacon frames on both the HRF link and the HPLC link, but when there is a conflict between the distribution network and the marketing network, CCO does not send beacon frames on the HPLC link. When there is a conflict between the distribution network and the marketing network, if the beacon time slot of PCO/STA falls in the beacon time slot of the marketing network, the beacon frame is sent on the HRF link; otherwise, PCO and STA perform HPLC channel detection before sending beacon frames: if the HPLC channel is idle, beacon frames are sent on both the HPLC link and the HRF link; if the HPLC channel is not idle, beacon frames are only sent on the HRF link. Select the sending link according to the service type. This solution does not require additional customization of the HPLC frequency division band, nor does it require coordination of the beacon time slot bandwidth with the marketing network.
