Detailed Description
In order to make the technical solution of the present specification better understood by those skilled in the art, the technical solution of the present specification embodiment will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present specification, and it is apparent that the described embodiment is only a part of the embodiment of the present specification, but not all the embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.
HPLC (High Speed Power Line Communication), also known as high-speed power line carrier communication or broadband power line carrier communication, is a communication technology that performs data transmission on a voltage power line. The HPLC network takes the power line as a communication medium to realize the convergence, transmission and interaction of the power consumption information of the power consumer.
Referring to fig. 1, fig. 1 is a schematic network topology diagram of an HPLC network according to an embodiment of the present disclosure. The HPLC network is a tree network topology which takes a master node as a center and connects the multistage association of all slave nodes in the HPLC network. The HPLC network comprises a master node and a plurality of slave nodes connected with the master node, wherein the slave nodes can be connected in one stage or in multiple stages.
The master node in the HPLC network may be a central coordinator (Central Coordinator, CCO). The plurality of slave nodes may comprise one or more proxy nodes or one or more station nodes, i.e. the slave nodes may be proxy nodes or station nodes. The proxy node in the HPLC network may be a proxy coordinator (Proxy Coordinator, PCO) for a relay proxy. The Station node in the HPLC network may be a Station (STA) for completing network access. A certain slave node in the HPLC network has a corresponding neighbor node, and the neighbor node corresponding to the slave node refers to a slave node or a master node capable of carrying out carrier communication with the slave node.
After networking is completed, the slave nodes in the HPLC network can evaluate according to the receiving and transmitting conditions of the discovery list of the peripheral neighbor nodes so as to select relatively better proxy nodes, and network optimization is realized through the change of the proxy nodes. The agent node change can be periodically performed, the period of the agent node change is related to the number of levels of the agent node, and the larger the number of levels of the agent node is, the larger the period of the agent node change is. In the related art, the evaluation of the agent node during the change can be performed according to the communication success rate, the level of the node and the corresponding signal-to-noise ratio characteristic.
However, the logic topology of the HPLC network is relatively uncertain due to the time variability of power line interference, the electricity usage habits of residential users, and the like. When the load change is large due to power line interference or electricity utilization habit of resident users and the like of an HPLC network of a certain area, the network optimization method for replacing proxy nodes in the related technology is evaluated according to the communication success rate of neighbor nodes, the number of stages of the nodes and the corresponding signal to noise ratio characteristics, so that the replacement of the proxy nodes in the HPLC network becomes more frequent, and the meter reading rate and the cost control success rate of the area are affected.
With continued reference to fig. 1, there are three phase physical line branches A, B, C in the hplc network. The CCO may operate on three phases A, B, C simultaneously to communicate with PCOs or STAs on the physical line branches of three phases A, B, C. The PCO or STA may operate on one of the physical line branches of the A, B, C phase. According to the network optimization method for replacing the proxy node by evaluating according to the communication success rate of the neighbor node, the number of stages of the node and the corresponding signal-to-noise ratio characteristics in the related art, the cross-phase data transmission in the HPLC network is easy to cause, and the communication effect of the cross-phase data transmission in the HPLC network is poor.
Therefore, it is necessary to provide an HPLC network optimization method, so that a slave node can receive slave phase information corresponding to the slave node distributed by a master node after networking is completed, and receive neighbor phase information corresponding to a neighbor node sent by a neighbor node, and evaluate proxy nodes according to the slave phase information and the neighbor phase information, so as to determine a better proxy node of the slave node, and realize convergence optimization of an HPLC network.
The present disclosure provides an HPLC optimization method, referring to fig. 2, fig. 2 is a schematic flow chart of an HPLC network optimization method provided in this embodiment, where the method includes steps according to the flow chart, but may include more or less steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one implementation of a plurality of step execution orders and does not represent a unique execution order. In actual system or server product execution, the methods illustrated in the embodiments may be performed sequentially or in parallel (e.g., in parallel processors or in the context of multi-threaded processing). The HPLC optimization method can be applied to the slave nodes in the HPLC network, and specifically as shown in FIG. 2, the HPLC network optimization method can comprise the following steps.
Step S210: and receiving slave phase information distributed by the master node after the HPLC network networking is completed, and receiving maintenance message information sent by the neighbor node.
The slave phase information may be used to describe the physical phase to which the slave node belongs, or to describe the phase to which the physical line branch to which the slave node operates belongs.
In some cases, in the evaluation process of the proxy node, the change condition of the neighbor node can be judged through the maintenance message information of the neighbor node, or the channel quality of the neighbor node can be judged through the maintenance message information, so that whether the neighbor node can be used as a new proxy node can be judged. Meanwhile, in order to reduce the frequency of the change of the proxy node, the neighbor node which can be used as a new proxy node can be evaluated based on the phase information, so that a better proxy node can be selected. In this embodiment, the slave node may receive the slave phase information distributed by the master node after the HPLC network networking is completed and receive the maintenance message information sent by the neighbor node, so that the subsequent slave node may determine a better proxy node according to the received slave phase information and the maintenance message information.
Step S220: if the neighbor node can be used as the primary proxy node of the slave node according to the maintenance message information, comparing the slave phase information with the neighbor phase information carried by the maintenance message information to obtain a phase comparison result.
The neighbor phase information is used for describing the physical phase of the neighbor node.
In some cases, the slave node may determine the channel quality of the neighboring nodes and the change condition of the neighboring nodes according to the maintenance message information of the neighboring nodes. In order to enable the evaluation of the proxy node according to the phase information, the maintenance message information sent by the neighbor node may carry the neighbor phase information of the neighbor node.
In this embodiment, the slave node may determine whether the neighboring node can be used as the preliminary proxy node of the slave node according to the maintenance message information sent by the neighboring node, if it is determined that the neighboring node can be used as the preliminary proxy node of the slave node according to the maintenance message information, the preliminary proxy node may be evaluated according to the slave phase information in combination with the neighboring phase information, that is, the slave phase information of the slave node may be compared with the neighboring phase information of the neighboring node that can be used as the preliminary proxy node of the slave node, so as to obtain a phase comparison result, so that convergence optimization may be performed according to the phase comparison result. Specifically, comparing the slave phase information with the neighbor phase information may refer to comparing whether the slave phase information is consistent with the neighbor phase information, and the obtained phase comparison result may be that the neighbor phase information is consistent with or inconsistent with the slave phase information.
Step S230: if the phase comparison result shows that the neighbor node can serve as a target proxy node of the slave node, a proxy change request is initiated to the master node.
The proxy change request is used for requesting the master node to set the neighbor node as a target proxy node of the slave node.
In the present embodiment, if the phase comparison result is that the neighbor phase information matches the slave phase information, it indicates that the neighbor node can be a target proxy node of the slave node. If the neighbor node can act as a preliminary proxy node for the slave node, and the phase comparison result indicates that the neighbor node can act as a target proxy node for the slave node, the slave node may initiate a proxy change request to the master node, so that the master node sets the neighbor node as the target proxy node for the slave node.
In the above embodiment, by receiving the slave phase information distributed by the master node after the networking is completed and receiving the maintenance message information sent by the neighbor node, the evaluation of the proxy node and the initiation of the proxy change request to the master node can be performed by combining the channel quality of the neighbor node, the change condition of the neighbor node and the neighbor phase information of the neighbor node, so as to determine the target proxy node with the same phase as the slave node, and complete the convergence and optimization of the HPLC network; compared with the process of evaluating and changing the proxy node directly according to the maintenance message information, the method can reduce the phase error of the HPLC network topology, reduce the changing frequency of the proxy node, further reduce the influence on the business such as meter reading and control in the HPLC network, and improve the communication stability of the HPLC network. Meanwhile, the same phase data transmission duty ratio in the HPLC network can be improved, the cross-phase data transmission duty ratio in the HPLC network can be reduced, and the communication effect of the HPLC network is improved.
In some embodiments, receiving slave phase information that the master node distributes after HPLC network networking is complete may include: and receiving a meter reading service message sent by the master node after the HPLC network networking is completed. The meter reading service message carries slave phase information of the slave node.
In some cases, after the HPLC networking is completed, the master node may determine slave phase information of the slave node in the HPLC network, and may send the slave phase information to a corresponding slave node in the HPLC network, where the slave node may receive the slave phase information corresponding to the slave node sent by the master node.
In this embodiment, the slave node may receive the meter reading service message carrying the slave node sent by the master node after the HPLC network networking is completed. In particular, the HPLC network application layer protocol may define meter reading service messages with service data interactions between the master node and the slave node. Referring to fig. 3, the meter reading service message may include a protocol version number, a frame header length, a reserved field, a protocol type of forwarding data, a forwarding data length, a message sequence number, a device timeout time, an option word, data, and so on. Referring to fig. 4, the master node may send the slave phase information of the slave node to the corresponding slave node by using the concurrent meter reading service message. Illustratively, the master node may identify that the HPLC network networking is complete after 8 beacon periods, which may refer to the time intervals during which the master node transmits beacon frames, have not received association requests sent by slave nodes in the HPLC network. The master node may extend the slave phase information through a reserved field in the meter reading service message, that is, the meter reading service message carries the slave phase information of the slave node, so that after the slave node receives the meter reading service message issued by the master node, the master node analyzes the meter reading service message to obtain the corresponding slave phase information.
In the above embodiment, the slave node receives the meter reading service message sent by the master node, so as to obtain the slave phase information corresponding to the slave node, so that the link load of the HPLC network can be reduced, the influence on the transmission of service data such as meter reading and control in the HPLC network can be reduced, and the communication stability of the HPLC network can be further improved.
In some embodiments, referring to fig. 5 and 6, the hplc network optimization method may further include the following steps.
Step S510: and receiving a zero crossing point moment acquisition indication message issued by the main node.
In some cases, after the HPLC network networking is completed, the master node may perform phase identification on slave phase information of each slave node in the HPLC network. The HPLC network has A, B, C slave nodes with the same phase information, the same power frequency period of the power line and the same zero crossing point moment, and the slave nodes with different phase information have the same power frequency period of the power line but different zero crossing point moments, so that a method of comparing the zero crossing point moments can be adopted to identify the slave phase information of each slave node in the HPLC network.
In this embodiment, the slave node may receive the zero crossing point time acquisition indication packet issued by the master node, so as to facilitate subsequent zero crossing point time acquisition. Meanwhile, the master node can acquire the zero crossing point moments of the three phases A, B, C.
Step S520: and acquiring the zero crossing point moment according to the zero crossing point moment acquisition indication message.
In this embodiment, after receiving the indication packet collected at the zero crossing point time, the slave node may collect the zero crossing point time according to the indication packet collected at the zero crossing point time, and obtain the zero crossing point time of the slave node.
Step S530: and sending a zero crossing point time notification message to the master node so that the master node compares the phase information corresponding to the master node with the zero crossing point time corresponding to the slave node carried by the zero crossing point time notification message, and determining the slave phase information of the slave node.
In this embodiment, after the slave node completes the collection of the zero crossing point time, the slave node may report the message through the zero crossing point time, and report the zero crossing point time collected by the slave node, so that the master node may compare and calculate the zero crossing point time reported by the slave node with the zero crossing point time of the master node, and obtain the slave phase information to which the slave node belongs.
In the above embodiment, the indication message is collected at the zero crossing point moment sent by the master node, the zero crossing point moment is collected, and the message is informed at the zero crossing point moment, so that the master node determines the slave phase information of the slave node. In this way, the slave phase information of each slave node in the HPLC network can be identified, and the subsequent convergence and optimization of the HPLC network based on the slave phase information of the slave node can be realized.
In some implementations, the maintenance message information can include discovery list messages and beacon frames. The discovery list message may carry neighbor phase information. If it is determined that the neighboring node can be used as a preliminary proxy node of the slave node according to the maintenance message information, the method may include: if the beacon frame sent by the neighbor node is received and the neighbor node is contained in the discovery list message, the neighbor node is judged to be capable of serving as a primary proxy node of the slave node.
In some cases, after networking is completed, the master node and each slave node in the HPLC network may periodically send a discovery list packet of the node, where the discovery list packet carries information such as a discovery list of the node. Each slave node can acquire more comprehensive neighbor node information by receiving the discovery list message, thereby acquiring a more detailed discovery list of the slave node. Specifically, after networking is completed, a master node or a slave node in the HPLC network may broadcast a discovery list message periodically. Specifically, a master node or slave node in the HPLC network may also periodically send beacon frames.
In this embodiment, referring to fig. 7, a slave node may receive a discovery list message carrying neighbor phase information sent by a neighbor node, that is, the neighbor node may perform phase notification through the discovery list message, and the slave node may obtain neighbor phase information of the neighbor node by receiving the discovery list message. The slave node may also receive beacon frames transmitted by neighbor nodes. The slave node can judge the change condition of the neighbor node by judging the condition of receiving the discovery list message of the neighbor node and the condition of receiving the beacon frame of the neighbor node, thereby judging whether the neighbor node can be used as the preliminary proxy node of the slave node, and being convenient for judging whether the neighbor node can be used as the target proxy node of the slave node by combining the slave phase information of the slave node. Specifically, the slave node may receive the beacon frame sent by the neighbor node, and if the neighbor node sending the beacon frame is located in the discovery list message received by the slave node, determine that the neighbor node may be used as the preliminary proxy node of the slave node.
In the above embodiment, the slave node may determine whether the neighbor node can be used as the preliminary proxy node of the slave node by receiving the discovery list message and the beacon frame, and provide a basis for subsequent evaluation of the proxy node by combining the slave phase information and the neighbor phase information.
In some embodiments, the discovery list message may carry the success rate of the uplink and downlink communications of the neighbor node. After determining that the neighboring node can act as a preliminary proxy node for the slave node, the HPLC network optimization method may further include the steps of: and evaluating the neighbor nodes which can be used as the preliminary proxy nodes according to the uplink and downlink communication success rate of the neighbor nodes.
The uplink and downlink communication success rate of the neighbor node is the communication success rate between the neighbor node and the proxy node of the neighbor node.
In this embodiment, in the process of evaluating the proxy node, if it is determined that the neighboring node can be used as the preliminary proxy node of the slave node, the neighboring node that can be used as the preliminary proxy node may be further evaluated according to the uplink and downlink communication success rate of the neighboring node, so that the slave node may combine the uplink and downlink communication success rate of the neighboring node with the phase information of the neighboring node to determine whether the neighboring node can be used as the target proxy node of the slave node.
In some embodiments, after determining that the neighboring node is capable of acting as a preliminary proxy node for the slave node, the HPLC network optimization method may further include the steps of: acquiring a signal-to-noise ratio corresponding to a neighbor node; and evaluating the neighbor nodes which can serve as the preliminary proxy nodes according to the signal-to-noise ratios corresponding to the neighbor nodes.
In this embodiment, in the process of evaluating the proxy node, if it is determined that the neighboring node can be used as the preliminary proxy node of the slave node, the signal-to-noise ratio corresponding to the neighboring node may be further obtained, and the neighboring node may be further evaluated according to the signal-to-noise ratio corresponding to the neighboring node, so that the slave node may combine the signal-to-noise ratio corresponding to the neighboring node and the phase information of the neighboring node to determine whether the neighboring node can be used as the target proxy node of the slave node.
