The method includes: verifying the consistency of the communication language and interaction process between the device under test and the standard device, determining the protocol consistency performance of the device under test; verifying whether the transmission performance and receiving performance of the device under test meet the standard requirements, and determining the communication performance; verifying the compatibility of the device under test with the standard device in the simulation environment, and determining the interoperability performance; and judging the interoperability performance of low-voltage power line carrier communication based on the protocol consistency performance, communication performance and interoperability performance.

[0005] Prior art document 2 (CN112711919A) discloses a low-voltage power line broadband carrier communication protocol consistency test system and method. The system includes: a software platform, which is used to manage test cases, select case runs, and record system operation logs, and calculate the consistency of the behavior of the broadband carrier communication device to be tested with the standard protocol; a transparent physical access unit, which is responsible for sending test commands to the carrier channel and reporting the communication message of the carrier channel to the software platform; a carrier bus channel access unit, which is used to simulate the on-site carrier communication scene and provide a test environment for the broadband carrier communication device to be tested; a device application interface monitoring unit, which is used to simulate the upper application service of the broadband carrier communication device to be tested, and monitor the communication behavior and business behavior of the broadband carrier communication device to be tested.

Each experiment can only test a single device, and the equipment of the entire link must be disassembled and returned to the laboratory for separate experiments. It cannot be used for on-site testing of all equipment in the entire link of the low-voltage substation. All nodes except the device to be tested are completed by simulation, including the simulation of test scenarios, such as interference noise, attenuation of the carrier channel, etc. The communication behavior of all communication nodes except the broadband carrier communication device to be tested in a specific scenario is realized through simulation. The accuracy of the test results is affected by the simulation model and may not match the on-site results. Summary of the invention

[0058] In order to more clearly illustrate the technical solution of the present invention, the present invention will be further described below; obviously, the following description is only a part of the embodiments, and for ordinary technicians in the field, the technical solution of the present invention can also be applied to other similar scenarios based on these without creative work; in order to more clearly illustrate the technical solution of the present invention, the technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings:

[0059] like Figure 1 and Figure 2 As shown, embodiment 1 of the present invention provides a low-voltage substation power procurement full-link message compliance and consistency testing method, which is applied to an electricity consumption information collection system. The electricity consumption information collection system includes a concentrator, a collector and a smart meter, and the concentrator includes a CCO module.

[0060] It can be understood that the collector is used to convert serial communication into HPLC communication, and the collector can be a carrier module, so that the collector and the smart meter can form a carrier meter. The power consumption information collection system can include a concentrator and a carrier meter.

[0061] The method comprises the following steps:

[0062] Step 1: Obtain the test case for the electricity consumption information collection service.

[0063] Preferably, the test case set includes test cases generated according to meter reading and event reporting.

[0064] Before step 1, the method also includes formulating a test case set according to the business requirements and processes of electricity consumption information collection, including meter reading, event reporting, etc., and using the test cases in turn to detect the compliance and consistency of the entire link message.

[0065] Preferably, each test case in the test case set also includes corresponding test messages and a message compliance library. The construction of the message compliance library is based on the State Grid's "Electric Power User Electricity Consumption Information Collection System" series of standards and the uplink and downlink communication protocol standards of the concentrator, CCO, collector, and smart meter to build compliant receiving and sending messages for each device, and use this as the benchmark message to build a compliance message library.

[0066] Preferably, a prompt word template is constructed according to business requirements and processes, and the prompt word template is input into a large language model, which instructs the large language model to automatically generate test cases required by the prompt word template. The test cases include test cases that meet the message standards and test cases that do not meet the message standards. In this way, the compliance and consistency of the message can be tested more comprehensively and accurately, and the manual generation of test cases can be reduced, thereby improving the test rate.

[0067] Step 2: Select a test case from the power consumption information collection service test case set, and convert the test case into a test message instruction. After there are no unfinished instructions in the monitoring concentrator, send the test message instruction to the concentrator, and the concentrator processes the test message instruction according to the preset logic.

[0068] After monitoring that there are no unfinished commands in the concentrator, a test message command is sent to the concentrator to avoid command conflicts or data errors.

[0069] In step 2, the test message command is sent to the concentrator, which processes the message command and sends it to the CCO module, which sends it to the collector, which sends it to the smart meter, and the smart meter responds and reports it to the collector, which reports it to the CCO module, which reports it to the concentrator. In this way, some functions of the master station can be simulated to receive and send concentrator messages instead of the master station.

[0070] Step 3: Collect the received messages and sent messages corresponding to the CCO module, collector and smart meter, and verify whether the message format and message structure of the received messages and the sent messages are compliant to obtain a first compliance verification result.

[0071] Specifically, the received and sent messages of all devices in the entire link, including the concentrator carrier communication module CCO, the collector, and the smart meter, are collected. The message format and structure are first verified and compared with the benchmark messages in the compliance message library. According to the message format specification, the message structure is segmented, each segment is a label, and the message length is used as the first label. The collected message is compared with the benchmark message according to each label to determine whether it meets the specification requirements.

[0072] Furthermore, the verification of the message format and structure includes: performing a syntax check on the message; if the message follows the correct syntax rules, detecting whether the message contains all necessary elements and fields, and whether the organization structure of the message is correct; for example, whether the first bit of the message is the data defined in the preset standard; checking whether the data type of each field in the message is correct; checking whether the corresponding field value in the message is within the allowed range; checking whether the optional fields in the message exist, and if so, checking whether their values ​​meet the preset standards; checking whether the message uses the correct encoding and character set; checking whether the field values ​​in the message meet specific conditional logic or dependencies; checking whether the message meets the requirements of secure transmission, such as encryption, signing, etc.; checking whether the message can be correctly parsed by different versions of the system, that is, the compatibility check of the message.

[0073] Preferably, the entire link is monitored for messages, and when a message is detected, a message collection operation is performed.

[0074] The step 3 specifically includes the following steps according to the time sequence:

[0075] Step 3.1: Collect the downlink received message of the CCO module, and compare the message format and message structure of the downlink received message of the CCO module with the CCO downlink received reference message in the compliance message library to obtain a second compliance verification result;

[0076] Step 3.2: Collect the downlink transmission message of the CCO module, and compare the message format and message structure of the downlink transmission message of the CCO module with the CCO downlink transmission benchmark message in the compliance message library to obtain a third compliance verification result;

[0077] Step 3.3: Collect the downlink received message of the collector, and compare the message format and message structure of the downlink received message of the collector with the downlink sent and received message of the collector in the compliance message library to obtain a fourth compliance verification result;

[0078] Step 3.4: Collect the downlink sent message of the collector, and compare the message format and message structure of the downlink sent message of the collector with the downlink sent benchmark message of the collector in the compliance message library to obtain the fifth compliance verification result;

[0079] Step 3.5: Collect the received message of the smart meter, and compare the message format and message structure of the received message of the smart meter with the downlink received reference message of the smart meter in the compliance message library to obtain the sixth compliance verification result;

[0080] Step 3.6: Collect the uplink received message of the collector, and compare the message format and message structure of the uplink received message of the collector with the uplink received reference message of the collector in the compliance message library to obtain the seventh compliance verification result;

[0081] Step 3.7: the collector sends an uplink message, and compares the message format and message structure of the collector's uplink message with the collector's uplink sending benchmark message in the compliance message library to obtain an eighth compliance verification result;

[0082] Step 3.8: Collect the uplink received message of the CCO module, and compare the message format and message structure of the uplink received message of the CCO module with the uplink received reference message of the CCO module in the compliance message library to obtain the ninth compliance verification result;

[0083] Step 3.9: Collect the uplink sent message of the CCO module, and compare the message format and message structure of the uplink sent message of the CCO module with the uplink sent benchmark message of the CCO module in the compliance message library to obtain the tenth compliance verification result.

[0084] Step 4: Parse the received message and the sent message to obtain the received message content and the sent message content, and perform consistency verification on the received message content and the sent message content to obtain a first content consistency verification result.

[0085] Preferably, the received message information is stored according to the receiving time sequence, and the consistency of the received and sent message contents is verified.

[0086] Specifically, step 4 includes:

[0087] Parse the messages collected in steps 3.1 to 3.9 respectively to obtain the corresponding message contents;

[0088] Performing message content consistency verification on the downlink received message of the CCO module and the test case to obtain a second content consistency verification result;

[0089] Performing message content consistency verification on the downlink sent message of the CCO module and the downlink sent message of the CCO module to obtain a third content consistency verification result;

[0090] Performing message content consistency verification on the downlink sent message of the CCO module and the downlink received message of the collector to obtain a fourth content consistency verification result;

[0092] Performing message content consistency determination on the received message of the smart meter and the uplink received message of the collector to obtain a sixth content consistency verification result;

[0093] Performing message content consistency determination on the uplink received message of the collector and the uplink sent message of the collector to obtain a seventh content consistency verification result;

[0094] Performing message content consistency determination on the uplink sent message of the collector and the uplink received message of the CCO module to obtain an eighth content consistency verification result;

[0095] A message content consistency determination is performed on the uplink received message of the CCO module and the uplink sent message of the CCO module to obtain a ninth content consistency verification result.

[0096] Step 5: Determine the device generating the abnormal message according to the first compliance verification result and the first content consistency verification result.

[0097] Specifically, the device generating the abnormal message is determined based on the time sequence, the location information of the non-compliant message, and the location information of the message with inconsistent content.

[0098] Preferably, the first compliance verification result includes the second compliance verification result to the tenth compliance verification result, and the first content consistency verification result includes the second content consistency verification result to the ninth content consistency verification result.

[0099] In step 5, if the second compliance verification result is that the downlink received message of the CCO module is non-compliant, or the second content consistency verification result is that the downlink received message of the CCO module is inconsistent with the message content of the test case, the concentrator is determined to be a message abnormality device.

[0100] If the fifth compliance verification result is that the collector's downlink received message is compliant, and the sixth content consistency verification result is that the message contents of the collector's downlink received message and the collector's downlink sent message are inconsistent, or the fifth compliance verification result is that the collector's downlink sent message is non-compliant, then the collector is determined to be a message abnormality device; and / or, if the seventh compliance verification result is that the collector's uplink received message is compliant and the seventh content consistency verification result is that the collector's uplink received message and the collector's uplink sent message are inconsistent, or the seventh compliance verification result is that the collector's uplink sent message is non-compliant, then the collector is determined to be a message abnormality device.

[0101] If the sixth compliance verification result is that the received message of the smart meter is compliant, and the seventh content consistency verification result is that the message content of the received message of the smart meter and the uplink received message of the collector are inconsistent, or the sixth compliance verification result is that the uplink received message of the collector is not compliant, then the smart meter is determined to be a message abnormality device.

[0102] If the eighth compliance verification result is that the uplink message sent by the collector is compliant and the eighth content consistency verification result is that the message content of the uplink message sent by the collector is inconsistent with the uplink received message of the CCO module, then the power line communication environment is determined to be abnormal; and / or, if the third compliance verification result is that the downlink message sent by the CCO module is compliant and the fourth content consistency verification result is that the message content of the downlink message sent by the CCO module is inconsistent with the downlink received message of the collector, then the power line communication environment is determined to be abnormal.

[0103] If the second compliance verification result is that the downlink message sent by the CCO module is compliant and the third content consistency verification result is that the downlink message sent by the CCO module and the content of the downlink message sent by the CCO module are inconsistent, or the second compliance verification result is that the downlink message sent by the CCO module is not compliant, then the CCO module is determined to be a message abnormality device; and / or, if the tenth compliance verification result is that the uplink received message of the CCO module is compliant and the ninth content consistency verification result is that the message content of the uplink received message of the CCO module and the uplink sent message of the CCO module are inconsistent, or the tenth compliance verification result is that the uplink sent message of the CCO module is not compliant, then the CCO module is determined to be a message abnormality device.

[0104] Preferably, after step 5, the method further comprises outputting the determined message anomaly generating device and displaying detailed abnormal message information, i.e., non-compliance or inconsistency information. In this way, generating detailed abnormal message information can record the test results and problems found, and provide a feedback mechanism to improve message design.
