Description

Technical Field

[0001] The invention relates to an online monitoring method based on HPLC and HRF dual-mode communication, belonging to the technical field of dual-mode communication. Background Art

[0002] The dual-mode communication energy meter adopts dual-mode communication technology to realize the communication connection and two-way data transmission between the smart energy meter terminal and the power center. Dual-mode communication includes multiple modules, among which the dual-mode communication technology of HPLC module (high-speed broadband power line carrier communication module) + HRF module (micro-power wireless communication module) is more advanced. The HPLC module has the advantages of fast communication rate, stable signal and high automation level. The HRF module is highly flexible and easy to maintain, making the HPLC module and the HRF module complement each other to form a more complete power system communication network.

[0003] When the HPLC module is affected by line quality or restricted in use in specific scenarios, the problem can be avoided by switching to the HRF module. In the smart grid system, the core difficulty lies in how to accurately identify the abnormality of the HPLC module communication signal and switch to the HRF module at the right time while monitoring and processing the incoming and outgoing data in real time to achieve stable and efficient overall operation of the HPLC system.

[0004] Usually, the switching between the HPLC module and the HRF module is coordinated and managed by the main control chip on the smart power meter. However, if there is a problem with the signal sent by the HPLC module to the power center server, and the power center server identifies that a certain HPLC module has a problem, it will locate the problematic HPLC module and send an HRF switching signal. Since this process requires multiple steps to implement, it is difficult to realize the HRF switching action in real time or automatically, which causes the abnormal data in the power center's power data to continue to accumulate and have a greater impact. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide an online monitoring method based on HPLC and HRF dual-mode communication.

[0006] According to an embodiment of the present invention, a first solution is provided: an online monitoring method based on HPLC and HRF dual-mode communication, comprising the following steps:

[0007] Acquire node information of the target node electric energy meter, wherein the node information includes the node number and signal timing information of the target node electric energy meter;

[0014] Furthermore, the step of parsing the node number and obtaining the strongly related HPLC module of the electric energy meter of the previous adjacent node includes:

[0015] Parse the node number and obtain the node level, auxiliary equipment address, and auxiliary equipment level of the electric energy meter of the previous adjacent node;

[0016] According to the node level of the electric energy meter of the previous adjacent node of the target, the node number group of the same level of electric energy meters is obtained, and the node number of each node number group of the same level corresponds to a node HPLC module of the same level;

[0020] Further, in the equal-interval monitoring mode, a strongly correlated monitoring object group is generated for the strongly correlated HPLC modules, and HPLC modules of nodes at the same level, or HPLC modules of nodes at the same device, or HPLC modules of nodes at the same level of devices within the strongly correlated object group are obtained for regional communication quality monitoring and comparison;

[0024] The step of generating the preliminary judgment result is to evaluate the generation parameters of the communication quality monitoring signal according to the historical routine test parameters of the HPLC module of the previous adjacent node recorded by the target node and obtain the preliminary judgment result of the abnormal signal.

If the reverse test result is consistent with the initial judgment result of the abnormal signal, an HRF switching signal is generated. If not, an abnormal alarm signal is generated.

If the heterogeneous comparison test result is consistent with the initial judgment result of the abnormal signal, an HRF switching signal is generated. If not, an abnormal alarm signal is generated.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of this application.

[0056] Embodiment 1

[0057] This scheme involves a HPLC communication network structure, such as Figure 2 As shown, the highest level of the HPLC communication network structure is the power center server in the same power meter system. In the same HPLC communication network system, the power meters are connected to the power center server in a tree structure and exchange data. The first-level node power meters and second-level node power meters referred to in this case refer to the node distance between the power meters and the power center server. In the actual network layout, there is usually no difference in upper and lower management authority between the first-level node power meters and the second-level node power meters.

[0058] This embodiment provides an online monitoring method based on HPLC and HRF dual-mode communication, such as Figure 1 As shown, the following steps are included:

[0059] S101: Acquire node information of a target node electric energy meter, where the node information includes a node number and signal timing information of the target node electric energy meter;

[0060] The target node electric energy meter can be an electric energy meter actively found or monitored by the power center server, or can be any one of all electric energy meters monitored in real time in the HPLC communication network structure.

[0061] The node information includes a digital signal sent by the electric energy meter that is conventionally transmitted via the physical medium of the power line. The digital signal sent by each electric energy meter includes the node number of the electric energy meter. The node number includes the identity information of the electric energy meter. The digital signal sent by the electric energy meter of this scheme also includes signal timing information. The signal timing information represents the electric energy meter information of at least the previous node and the electric energy meter information of the next node of the target node electric energy meter, and identifies the position of the target node electric energy meter in the HPLC communication network structure.

[0062] S102: Acquire a communication quality monitoring signal between an electric energy meter of the target node and a previous adjacent node according to the signal timing information of the target node;

[0063] The communication quality monitoring signal of this solution is a monitoring signal for evaluating the communication quality of digital signals transmitted between adjacent node electric energy meters. The communication quality evaluation methods for digital signals include: working frequency band test, power spectrum density test, maximum input level test, maximum transmission power test, etc. This test can be a communication quality test implemented by a specific functional module, or it can be a monitoring parameter extraction and monitoring of certain parameters.

[0064] S103: monitoring the HPLC digital signal between the previous adjacent node and the target node according to the communication quality monitoring signal and obtaining a preliminary abnormal signal judgment result;

[0065] The accuracy or certainty of parameter monitoring is insufficient, but it also has the advantage of fast and effective data monitoring, and a preliminary identification and preliminary judgment of abnormalities can be made through communication quality monitoring.

[0066] S104: returning the abnormal signal initial judgment result and the reverse test signal to the electric energy meter of the previous adjacent node and obtaining the reverse test result of the previous adjacent node;

[0067] The reverse test may be a conventional carrier test or other protocol test or interoperability test, such as a data link consistency test, a data link channel access consistency test, etc.

[0068] S105: Determine whether to switch the HPLC communication mode of the previous adjacent node to the HRF communication mode according to the reverse test result.

[0069] The electric energy meter on each node should be equipped with a dual-mode communication chip to realize the switching from HPLC communication mode to HRF communication mode or vice versa.

[0070] This online monitoring method performs real-time point-to-point online monitoring of each HPLC module according to the characteristics of the HPLC communication network structure, and the monitoring does not add specific monitoring hardware and monitoring means beyond the scope of the original equipment, and only further monitors the communication quality of the existing monitoring means. The communication quality monitoring includes extracting parameters from existing conventional testing means and monitoring the parameters. The accuracy or certainty of parameter monitoring is insufficient, but it also has the advantage of fast and effective data monitoring. A preliminary identification and preliminary judgment of an anomaly can be made through communication quality monitoring. After the anomaly is found, a reverse test is performed through the next node (target node). The reverse test can be a conventional carrier test or other protocol test or interoperability test.

[0071] Embodiment 2

[0072] This embodiment specifically provides an online monitoring method based on HPLC and HRF dual-mode communication. Based on the solution of embodiment 1, the following solution is also specifically provided:

[0073] An online monitoring method based on HPLC and HRF dual-mode communication comprises the following steps:

[0074] Obtain node information of the target node electric energy meter, wherein the node information includes the node number and signal timing information of the target node electric energy meter; obtain a communication quality monitoring signal between the target node electric energy meter and the previous adjacent node based on the signal timing information of the target node; monitor the HPLC digital signal between the previous adjacent node and the target node based on the communication quality monitoring signal and obtain a preliminary abnormal signal judgment result; return the preliminary abnormal signal judgment result and the reverse test signal to the electric energy meter of the previous adjacent node and obtain a reverse test result of the previous adjacent node; and confirm whether to switch the HPLC communication mode of the previous adjacent node to the HRF communication mode based on the reverse test result.

[0075] Specifically, the modes for acquiring the node information of the electric energy meter of the target node include: equal interval monitoring mode, real-time monitoring mode, and abnormal response mode. The abnormal response mode includes: acquiring the node number of the previous adjacent node according to the reverse test result of the previous adjacent node, parsing the node number and acquiring the strongly correlated HPLC module of the electric energy meter of the previous adjacent node, and adjusting the mode of acquiring the node information of the target node and the strongly correlated HPLC module from the default equal interval monitoring mode to the real-time monitoring mode.

[0076] The step of parsing the node number and obtaining the strongly related HPLC module of the electric energy meter of the previous adjacent node includes:

[0077] Parse the node number and obtain the node level, auxiliary equipment address, and auxiliary equipment level of the electric energy meter of the previous adjacent node;

[0078] According to the node level of the electric energy meter of the previous adjacent node of the target, the node number group of the same level of electric energy meters is obtained, and the node number of each node number group of the same level corresponds to a node HPLC module of the same level;

[0079] According to the address of the auxiliary device, the same device node number group of the electric energy meter associated with the same auxiliary device is obtained, and the node number of each same device node number group corresponds to a same device node HPLC module;

[0080] According to the auxiliary equipment level, the same-level equipment node number group of the electric energy meters of other auxiliary equipment of the same level is obtained, and the node number of each same-level equipment node number group corresponds to a same-level equipment node HPLC module.

[0081] For example, if the Nth electric energy meter of the obtained secondary node is strongly associated according to the node level, then the remaining secondary node electric energy meters are strongly associated electric energy meters. For another example, if the Mth electric energy meter of the obtained secondary node is strongly associated according to the address of the auxiliary device, the multiple electric energy meters in the auxiliary device (system) are strongly associated electric energy meters. The multiple electric energy meters in the auxiliary device may be secondary nodes or other nodes. According to their node numbers, it can be confirmed whether the multiple electric energy meters are attached to the same auxiliary device.

[0082] The frequency sequence of communication quality monitoring of the obtained node number groups of the same level, the node number groups of the same device, and the device node number groups of the same level is adjusted and the initial judgment results of associated abnormalities are obtained. According to the initial judgment results of associated abnormalities, the associated abnormality HPLC module is obtained, and the mode of the associated abnormality HPLC module is adjusted from the default equal-interval monitoring mode to the real-time monitoring mode.

[0083] In the equal-interval monitoring mode, a strongly correlated monitoring object group is generated for the strongly correlated HPLC modules, and HPLC modules of nodes at the same level, or HPLC modules of nodes at the same device, or HPLC modules of nodes at the same level of equipment within the strongly correlated object group are obtained for regional communication quality monitoring and comparison;

[0084] For example, there are 30 electric energy meters in the same auxiliary equipment (system). The 30 electric energy meters are confirmed to be attached to the same auxiliary equipment according to the node number. The 30 electric energy meters may be in different positions of the communication network according to the different deployment logic of the HPLC communication network. However, if the initial judgment result of the abnormal signal sent by one of the electric energy meters is obtained, the abnormal state of the auxiliary equipment is indirectly revealed. This solution can switch to the real-time monitoring mode through the 30 electric energy meters at the first time to conduct intensive monitoring of the auxiliary equipment at the first time. This monitoring behavior not only monitors a specific abnormal signal through a single electric energy meter, but also forms a specific abnormal state analysis result for the auxiliary equipment through multiple abnormal signals of 30 electric energy meters. The abnormal state analysis results analyzed by multiple electric energy meters cannot be fed back by a single abnormal signal. This abnormal state analysis result includes high voltage abnormality of the auxiliary equipment group, abnormality of the series signal of the auxiliary equipment, etc. There are many forms of expression in the field of electric energy meters, which will not be described one by one here.

[0085] The method of regional communication quality monitoring and comparison includes: obtaining the same-level node test parameters of the same-level node HPLC module within the strongly related object group, or the same-level device node test parameters of the same-device node HPLC module, or the same-level device node test parameters of the same-level device node HPLC module, generating a group monitoring comparison signal with the same-level node test parameters, the same-device node test parameters and the same-level device node test parameters, performing group identification on the same category test parameters of the group monitoring comparison signal and obtaining the strong interference result of the HPLC module based on the group identification result, and sending the strong interference result to the power center server.

[0086] The group monitoring comparison signal includes: performing similar signal analysis on the node electric energy meters of the same level, performing similar signal analysis on the electric energy meters of the same device node, etc.

[0087] Furthermore, the electric energy meters of the same device node can also be subjected to sequential monitoring signal analysis or synchronous heterogeneous monitoring signal testing and analysis to obtain specific monitoring results through active detection. For example, 30 electric energy meters of the same accessory device are classified, and the first-class electric energy meters are synchronously tested to see whether the SOF frame with a long MPDU frame payload length of 72 and a long MAC frame header can be correctly processed, and the second-class electric energy meters are synchronously tested to see whether the SOF frame with a single-hop MAC frame header of the MPDU frame payload has an error message that causes an abnormality to the module under test. If both the first-class and second-class electric energy meters fail the test, the abnormality of the adjacent channel interference performance of the accessory device can be obtained more quickly.

[0088] The steps of obtaining a communication quality monitoring signal between the electric energy meter of the target node and the previous adjacent node according to the signal timing information of the target node, monitoring the HPLC digital signal between the previous adjacent node and the target node according to the communication quality monitoring signal and obtaining a preliminary abnormal signal judgment result include:

[0089] Monitoring signal generation step: obtaining a digital signal sent by the HPLC module of the previous adjacent node to the HPLC module of the current target node according to the signal timing information of the target node, performing a conventional carrier test on the digital signal and generating parameters according to the test results, wherein the communication quality monitoring signal includes conventional test parameters, and the conventional test parameters include test time and test frequency;

[0090] The step of generating the preliminary judgment result is to evaluate the generation parameters of the communication quality monitoring signal according to the historical routine test parameters of the HPLC module of the previous adjacent node recorded by the target node and obtain the preliminary judgment result of the abnormal signal.

[0091] The step of returning the abnormal signal initial judgment result and the reverse test signal to the electric energy meter of the previous adjacent node and obtaining the reverse test result of the previous adjacent node includes:

[0092] Reverse signal sending step: perform the same type of repeated test or heterogeneous comparison test on the upper adjacent node according to the test method corresponding to the communication quality monitoring signal.

[0093] If the same type of repeated test is implemented, the same type of repeated test is compared in real time at the target node and the reverse test result is obtained. If the reverse test result is consistent with the initial judgment result of the abnormal signal, an HRF switching signal is generated. If it is inconsistent, an abnormal alarm signal is generated.

[0094] If a heterogeneous comparison test is implemented, the heterogeneous comparison test result is obtained in real time at the target node. If the heterogeneous comparison test result is consistent with the initial judgment result of the abnormal signal, an HRF switching signal is generated. If not, an abnormal alarm signal is generated.

[0095] This solution has the advantages of fewer monitoring call programs, fast response speed, real-time monitoring and real-time feedback based on each node, and online resolution of communication failures through HRF, ensuring rapid discovery, rapid response and preliminary resolution of power network operation failures.

[0098] The information acquisition module 100 is used to acquire the node information of the target node electric energy meter, wherein the node information includes the node number and signal timing information of the target node electric energy meter;

[0099] A monitoring signal module 200 is used to obtain a communication quality monitoring signal between the electric energy meter of the target node and the previous adjacent node according to the signal timing information of the target node;

[0100] The preliminary judgment result module 300 is used to monitor the HPLC digital signal between the previous adjacent node and the target node according to the communication quality monitoring signal and obtain the preliminary judgment result of the abnormal signal;

[0101] The reverse test module 400 is used to return the abnormal signal initial judgment result and the reverse test signal to the electric energy meter of the previous adjacent node and obtain the reverse test result of the previous adjacent node;

[0102] The mode switching module 500 is used to determine whether to switch the HPLC communication mode of the previous adjacent node to the HRF communication mode according to the reverse test result.

[0103] This online monitoring device performs real-time point-to-point online monitoring of each HPLC module according to the characteristics of the HPLC communication network structure, and the monitoring does not add specific monitoring hardware and monitoring means beyond the scope of the original equipment, and only further monitors the communication quality of the existing monitoring means. The communication quality monitoring includes parameter extraction and parameter monitoring of existing conventional testing means. The accuracy or certainty of parameter monitoring is insufficient, but it also has the advantages of fast and effective data monitoring. It can perform a preliminary identification and preliminary judgment of an abnormality through communication quality monitoring, and perform a reverse test through the next node (target node) after the abnormality is found. The reverse test can be a conventional carrier test or other protocol test or interoperability test.
