[0053] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application.

[0054] Please refer to Figure 1 , the present application provides an evaluation method for a power line carrier communication network, which is used for an electronic device. The electronic device communicates with an acquisition device connected to the power line carrier communication network. The evaluation method includes:

[0055] 01. Receiving power line carrier communication messages collected by the acquisition device from the power line carrier communication network;

[0056] 02. Preprocessing the power line carrier communication messages to obtain power line message framed data;

[0058] 04. Evaluating according to the network topology information, site induction information, and / or service data information to obtain an evaluation result of the power line carrier communication network.

[0059] Please refer to Figure 2 , an evaluation device 10 for a power line carrier communication network is provided in an embodiment of the present application. The evaluation device 10 includes a communication module 110, a preprocessing module 120, an analysis module 130, and an evaluation module 140. Step 01 can be implemented by the communication module 110, step 02 can be implemented by the preprocessing module 120, step 03 can be implemented by the analysis module 130, and step 04 can be implemented by the evaluation module 140.

[0060] Or rather, the communication module 110 can be used to receive power line carrier communication messages collected by the acquisition device from the power line carrier communication network. The preprocessing module 120 can be used to preprocess the power line carrier communication messages to obtain power line message framed data. The analysis module 130 can be used to analyze and process the power line message framed data to obtain network topology information, site induction information, and service data information. The evaluation module 140 can be used to perform an evaluation based on the network topology information, site induction information, and / or service data information to obtain an evaluation result of the power line carrier communication network.

[0061] An embodiment of the present application also provides an electronic device. The electronic device communicates with an acquisition device connected to the power line carrier communication network. The electronic device includes a processor and a memory. Among them, the memory stores a computer program. When the computer program is executed by the processor, the processor executes the above-mentioned evaluation method for the power line carrier communication network. That is, the processor can be used to receive power line carrier communication messages collected by the acquisition device from the power line carrier communication network, preprocess the power line carrier communication messages to obtain power line message framed data, then analyze and process the power line message framed data to obtain network topology information, site induction information, and service data information, and perform an evaluation based on the network topology information, site induction information, and / or service data information to obtain an evaluation result of the power line carrier communication network.

[0062] In the evaluation method, evaluation device 10, and electronic device according to the embodiments of the present application, power line carrier communication messages are collected by a collection device, and then the electronic device performs preprocessing and parsing on the power line carrier communication messages to generate network topology information, site induction information, and service data information about the power line carrier communication network, and comprehensively evaluates the power line carrier communication network through the network topology information, site induction information, and / or service data information to obtain an evaluation result of the power line carrier communication network. In this way, the operability and convenience of the evaluation of the power line carrier communication network can be improved, the labor and time costs can be significantly reduced, and the evaluation solution can be given good popularizability. Moreover, since the power line carrier communication network is comprehensively evaluated through the network topology information, site induction information, and / or service data information of the power line carrier communication network, problems in the power line carrier communication network can be better discovered, thereby providing guidance for subsequent optimization of the power line carrier communication network.

[0063] In some embodiments, the evaluation device 10 may be a part of the electronic device. Or rather, the electronic device includes the evaluation device 10.

[0064] In some embodiments where the evaluation device 10 is a part of the electronic device, as software, the code segment corresponding to the evaluation device 10 may be stored on a memory and implemented by a processor to perform the foregoing functions. Or rather, the evaluation device 10 includes the foregoing computer program, or rather, the foregoing computer program includes the evaluation device 10.

[0065] In some embodiments where the evaluation device 10 is a part of the electronic device, as hardware, the evaluation device may be independent or added as an additional peripheral component to the electronic device. For example, when the evaluation device 10 is a part of the electronic device, the evaluation device 10 may be integrated into the processor.

[0066] The electronic device may be a mobile terminal device (such as a mobile phone, a tablet), a computer, or a server host, etc. For example, in some examples, the electronic device is described by taking a computer as an example. That is to say, the evaluation method of the power line carrier communication network and the evaluation device 10 may be applied to, but not limited to, a computer. The evaluation device 10 may be hardware or software pre-installed on the computer, and may execute the evaluation method when started and running on the computer.

[0067] It should be noted that the power line carrier communication network may be a high-speed power line communication (HPLC) network for low-voltage power lines. That is to say, the present application evaluates the HPLC network. The HPLC network is a broadband power line carrier technology for data transmission on power lines. HPLC uses the power line as a communication medium to realize a communication network for aggregating, transmitting, and interacting the electricity consumption information of low-voltage power users.

[0068] Please combine Figure 3 and Figure 4 , the acquisition device can be set in the HPLC network. The acquisition device can obtain the power line carrier communication message from the HPLC network through a coupling method. The HPLC network includes a concentrator, multiple smart meters, and power lines. The concentrator is connected to the smart meters and the smart meters are connected to each other through the power lines to form the HPLC network. Among them, the concentrator serves as the main node (Concentrator, CCO) of the HPLC network, some smart meters serve as the sub-nodes (Station, STA) of the HPLC network, and some smart meters serve as the proxy nodes (Proxy Coordinator, PCO) of the HPLC network.

[0069] Furthermore, the acquisition device can include one or multiple, and the specific number of the acquisition devices is not limited. When there is one acquisition device (for example Figure 3 ), the access position of the acquisition device can be at the power line connection point of the concentrator. In this way, the acquisition device can collect the power line carrier communication message at the concentrator. When there are multiple acquisition devices (for example Figure 4 ), multiple acquisition devices can be respectively deployed at the power line access points of different smart meters. In this way, the acquisition device can collect the power line carrier communication message at any power line access point. It should be noted that the reason for setting the acquisition device close to the smart meter or the concentrator is that the smart meter and the concentrator are connected to the power line, and the interface where the smart meter / concentrator is connected to the power line can also facilitate the installation of the acquisition device.

[0070] It can be understood that since the acquisition device only needs to obtain the power line carrier communication message of the HPLC network by coupling the power line, without directly reading data from the smart meter, it saves manpower and time costs, avoids secondary development and replacement of the existing network fixed deployment equipment, and because the power line carrier communication message is directly collected by coupling the power line, there are no specific requirements for the manufacturers, models, and versions of the smart meters and concentrators. At the same time, the acquisition position of the power line carrier communication message can be flexibly adjusted to cover deeper-level sites.

[0071] The electronic device can communicate with the acquisition device through wireless communication to jointly form an evaluation system of the power line carrier communication network, and the processor can obtain the power line carrier communication message from the acquisition device.

[0072] It should also be noted that the network topology refers to the logical composition mode of nodes and lines formed among smart meters, concentrators, and power line channels in the power line carrier communication network. The site summary information refers to all the information contained in each site (such as received information, sent information, etc.), and the service data information refers to the application layer service data information in the power line carrier communication message.

[0073] Please refer to Figure 5 , in some embodiments, step 02 includes:

[0074] 021, perform analog-to-digital conversion on the power line carrier communication message to obtain message data;

[0075] 022, locate the data frame header of the message data according to the preamble sequence of the message data;

[0076] 023, perform interception processing on the message data according to the data frame header to obtain power line message framed data.

[0077] Please further combine with Figure 2 , in some embodiments, steps 021 - 023 can be implemented by the preprocessing module 120. That is, the preprocessing module 120 can be used to perform analog-to-digital conversion on the power line carrier communication message to obtain message data, locate the data frame header of the message data according to the preamble sequence of the message data, and perform interception processing on the message data according to the data frame header to obtain power line message framed data.

[0078] In some embodiments, the processor can be used to perform analog-to-digital conversion on the power line carrier communication message to obtain message data, locate the data frame header of the message data according to the preamble sequence of the message data, and perform interception processing on the message data according to the data frame header to obtain power line message framed data.

[0079] It can be understood that the power line carrier communication message is transmitted as an analog signal in the power line carrier communication network, and the acquisition device acquires the power line carrier communication message from the power line carrier communication network in a coupling manner. Therefore, it is necessary to perform analog-to-digital conversion on the power line carrier communication message to convert it into message data in digital signal form.

[0080] The preamble sequence refers to a series of signals sent before the useful signal is sent. After the preamble signal is sent, the valid signal is immediately sent. The preamble sequence can locate the data frame header of the message data, so that the message data can be intercepted to only obtain the useful power line message framed data. In this way, the subsequent data processing amount can be reduced, thereby improving the evaluation efficiency of the power line carrier communication network.

[0081] Please refer to Figure 6 , in some embodiments, step 03 includes sub-steps:

[0082] 031. Obtain the preset site information in the power line carrier communication network from the network management software;

[0083] 032. Generate network topology information, site summary information, and service data information based on the preset site information and the power line message framed data.

[0084] Please further combine with Figure 2 , in some embodiments, sub-steps 031 and 032 can be implemented by the parsing module 130. Or rather, the parsing module 130 can be used to obtain the preset site information in the power line carrier communication network from the network management software, and generate network topology information, site summary information, and service data information based on the preset site information and the power line message framed data.

[0085] In some embodiments, the processor can be used to obtain the preset site information in the power line carrier communication network from the network management software, and generate network topology information, site summary information, and service data information based on the preset site information and the power line message framed data.

[0086] It can be understood that factors such as the installation location of the acquisition device and the data acquisition duration may cause the acquisition device to fail to obtain various types of power line carrier communication messages of all sites in the power line carrier communication network, resulting in certain information loss and affecting the comprehensiveness of the evaluation of the power line carrier communication network. Therefore, obtaining the preset site information in the power line carrier communication network from the network management software can assist the electronic device in collecting more comprehensive information. It can ensure the accuracy of the evaluation results of the power line carrier communication network based on the network topology information, site summary information, and service data information.

[0087] Please refer to Figure 7 , in some embodiments, step 03 further includes sub-steps:

[0088] 033. Parse the power line message framed data according to the frame parsing function and the low-voltage power line high-speed carrier communication standard to obtain the parsed data;

[0089] 034. Read the site identifier in the parsed data to sort out and generate network topology information;

[0090] 035. Take each site as a data structure, and summarize the data related to each site in the parsed data into the corresponding data structure to generate site summary information;

[0091] 036. Read the application layer message of the parsed data to generate service data information.

[0092] Please further combine with Figure 2, in some embodiments, sub-steps 033-036 may be implemented by the parsing module 130. Or rather, the parsing module 130 may also be used to parse the framed data of the power line message according to the frame parsing function and the high-speed carrier communication standard for low-voltage power lines to obtain parsed data, read the site identifier in the parsed data to sort out and generate network topology information, use each site as a data structure, summarize the data related to each site in the parsed data into the corresponding data structure to generate site summary information, and read the application layer message of the parsed data to generate service data information.

[0093] In some embodiments, the processor may be used to parse the framed data of the power line message according to the frame parsing function and the high-speed carrier communication standard for low-voltage power lines to obtain parsed data, read the site identifier in the parsed data to sort out and generate network topology information, use each site as a data structure, summarize the data related to each site in the parsed data into the corresponding data structure to generate site summary information, and read the application layer message of the parsed data to generate service data information.

[0094] It should be noted that in sub-step 033, the parsing process strictly follows the data frame information bit and data endian setting.

[0095] The site identifier may include the site's own identifier and its proxy site identifier, that is, in sub-step 034, read the identifier of each site's own (STA) and its proxy site's identifier (PCO) in the parsed data to sort out and generate network topology information.

[0096] The site summary information is the information obtained by summarizing all the information related to each site. In this way, it is convenient for subsequent viewing and algorithm operation calls.

[0097] Furthermore, the site summary information may include but is not limited to index statistical data information, classified frame transceiver information, cycle information of message timestamps, abnormal site information, and message parameter information.

[0098] Among them, the index statistical data information refers to the information obtained by statistically summarizing the index item data for evaluating communication quality. Among them, the index item data may include but is not limited to the uplink and downlink communication success rates, channel quality expressed in terms of signal-to-noise ratio, minimum communication success rate of multi-hop communication links, etc. The index item data may come from multiple messages. The index item data can be statistically summarized with the site identifier as an item to generate index statistical data information.

[0099] The classified frame transceiver information refers to the information of different types of data frames received and transmitted by each site. According to different types of data frames (such as beacon frames, network management message frames, etc.), the frame transceiver situation of each site is statistically obtained to obtain the classified frame transceiver information.

[0100] The periodic information of the message timestamp refers to the transmission period or reception period of the message. In the power line carrier communication standard, there are clear regulations on the periodicity of some data messages, that is, a sufficient number of messages must be sent within a certain time to ensure the normal operation of the network. Therefore, the network reference time of the relevant messages can be recorded to generate the periodic information of the message timestamp.

[0101] The abnormal site information can be obtained from the index statistical data information. Specifically, during the process of summarizing and statistically analyzing the index item data, the normal range of the index value can be preset in advance to timely identify the abnormal index and the site sending the abnormal information, and record and statistically analyze them to generate the abnormal site information.

[0102] The message parameters refer to the parameter data included in the message. It can be understood that the parameter data included in the message needs to follow certain rules. For example, it first needs to meet the protocol standard regulations. Secondly, during the communication process, some parameters need to be updated in real time according to the communication information interaction process. For example, the sequence number and timestamp of the PPDU need to be continuous, whether the data frame that needs to return an acknowledgment frame message after reception is counted into the corresponding acknowledgment frame, and whether the number of retransmissions of the data frame is set too large in a good channel environment, resulting in too low information transmission efficiency, etc.

[0103] In sub-step 036, the frame reception and transmission situations of each site can be combined, and the content of the application layer message in the parsed data can be read to generate the service data information.

[0104] Please refer to Figure 8 , in some embodiments, the evaluation result includes the site-level evaluation result, and step 04 includes sub-steps:

[0105] 041, score each site according to the index statistical data information through the first evaluation algorithm to generate the first evaluation score;

[0106] 042, determine the site-level evaluation result according to the first evaluation score and the index statistical data information.

[0107] Please further combine Figure 2 , in some embodiments, sub-steps 041 and 042 can be implemented by the evaluation module 140. Or rather, the evaluation module 140 can be used to score each site according to the index statistical data information through the first evaluation algorithm to generate the first evaluation score, and determine the site-level evaluation result according to the first evaluation score and the index statistical data information.

[0108] In some embodiments, the processor can be used to score each site according to the index statistical data information through the first evaluation algorithm to generate the first evaluation score, and determine the site-level evaluation result according to the first evaluation score and the index statistical data information.

[0109] The first evaluation algorithm can be a multi-index weighted evaluation algorithm. That is, each site is scored according to the index statistical data information of each site through the multi-index weighted evaluation algorithm, and the first evaluation score of each site is generated. Thus, the site-level evaluation result can be generated according to the first evaluation score of each site.

[0110] Please refer to Figure 9 , in some embodiments, the evaluation result includes a network-level evaluation result, and step 04 includes sub-steps:

[0111] 043, each site is scored according to the index statistical data information through the second evaluation algorithm to generate a second evaluation score;

[0112] 044, a network-level evaluation result is generated according to the second evaluation score, network topology information, and abnormal site information.

[0113] Please further combine with Figure 2 , in some embodiments, sub-steps 043 and 044 can be implemented by the evaluation module 140. Or rather, the evaluation module 140 can be used to score each site according to the index statistical data information through the second evaluation algorithm to generate a second evaluation score, and generate a network-level evaluation result according to the second evaluation score, network topology information, and abnormal site information.

[0114] In some embodiments, the processor can be used to score each site according to the index statistical data information through the second evaluation algorithm to generate a second evaluation score, and generate a network-level evaluation result according to the second evaluation score, network topology information, and abnormal site information.

[0115] The second evaluation algorithm can be a multi-index subjective and objective weighted evaluation algorithm. That is, each site is scored according to the index statistical data information of each site through the multi-index subjective and objective weighted evaluation algorithm to generate the second evaluation score of each site. After generating the second evaluation score, linear normalization processing can be performed on the second evaluation score, network topology information, and abnormal site information, and then weighted accumulation is performed to generate a network-level evaluation result. Thus, subsequent targeted optimization of the power line carrier communication network can be achieved according to the network-level evaluation result.

[0116] Please refer to Figure 10 , in some embodiments, the evaluation result includes abnormal warning information, and step 04 includes sub-steps:

[0117] 045, generate abnormal warning information according to at least one of network topology information, site induction information, service data information, or abnormal identification rules.

[0118] Please further combine with Figure 2, in some embodiments, sub-step 045 may be implemented by the evaluation module 140. That is to say, the evaluation module 140 may be used to generate an exception warning message based on at least one of network topology information, site induction information, service data information, or exception recognition rules.

[0119] In some embodiments, the processor may be used to generate an exception warning message based on at least one of network topology information, site induction information, service data information, or exception recognition rules.

[0120] It should be noted that the preset recognition rule may be a rule that, after a large amount of data collection and analysis, extracts the characteristics of known exceptions as a problem, summarizes them into an exception problem library, and correspondingly adds judgment conditions to the evaluation system to achieve the recognition of exception problems. The exception problem library and its corresponding judgment conditions can be updated through continuous data accumulation.

[0121] Specifically, an exception warning message may be generated based on one or more of exception site information, exception index data, site-level evaluation results, network-level evaluation results, and preset rules. In this way, subsequent targeted optimization of the power line carrier communication network can be achieved based on the exception warning message.

[0122] Please refer to Figure 11 , in some embodiments, the evaluation result includes a service flow evaluation result, and step 04 includes sub-steps:

[0123] 046, analyzing the service data information to generate a service flow evaluation result.
