Description

Technical Field

[0001] This invention relates to the field of electricity meter technology, and in particular to an automatic testing method for full traversal of electricity meter protocol data and an electricity meter. Background Technology

[0002] Currently, electricity meter protocols are often tested manually, line by line, to identify potential quality issues during development. Alternatively, the electricity meter is connected to a test bench, and a test program is written on a PC to communicate with the meter, read or set data or parameters, thus achieving the testing purpose. Clearly, manual testing is costly and may not uncover all protocol issues. Sometimes, test cases are poorly designed, leading to missed tests, or only normal tests are performed while anomaly tests are neglected, or anomaly tests are not comprehensively considered, resulting in quality problems. On the other hand, connecting the electricity meter to the test bench and writing test software on a PC to control the test bench requires purchasing expensive equipment, setting up a complex environment, and writing specialized test software. Testing requires running the test bench and connecting the electricity meter to the environment. Furthermore, due to the high cost of the equipment, it is difficult to allocate one test bench to each tester for testing and verification. Moreover, these methods can only perform random checks on produced electricity meters, failing to achieve comprehensive testing of every single meter. Therefore, there is an urgent need to propose an automatic testing method for the full traversal of electricity meter protocol data and an electricity meter to solve the technical problem of how to accurately and quickly perform automatic testing of the full traversal of electricity meter protocol data. Summary of the Invention

[0003] The main objective of this invention is to propose an automatic testing method for the full traversal of electricity meter protocol data and an electricity meter, aiming to solve the technical problem of how to accurately and quickly perform automatic testing of the full traversal of electricity meter protocol data.

[0004] To achieve the above objectives, the present invention provides an automatic testing method for the full traversal of electricity meter protocol data, wherein the automatic testing method for the full traversal of electricity meter protocol data includes the following steps:

[0005] S1. Model the protocols supported by the electricity meter and define the data format type of the electricity meter in the protocol;

[0006] S2. Establish a table of protocols to be tested for electricity meters. The main station request message generation module generates formal electricity meter protocol messages for each protocol in the table of protocols to be tested according to the electricity meter protocol specifications.

[0007] S3. Based on the format corresponding to the protocol in the protocol information table, generate normal test messages and abnormal test messages respectively, and expect normal responses and abnormal responses respectively;

[0008] S4. The virtual message receiving module places the protocol request message generated by the master station request message generation module into the communication port driver buffer of the energy meter. The energy meter executes the protocol processing flow according to the protocol request message in the communication port driver buffer.

[0009] S5. Statistically analyze the operation results of the electricity meter protocol. Repeat steps S2-S4 to complete the full traversal automatic test of all protocols in the protocol information table under test.

[0010] In one preferred embodiment, any protocol of the electricity meter includes a control code, a data identifier, and additional data.

[0011] In one preferred embodiment, the format of the additional data includes the length of the additional data, a normal padding interface, and an abnormal padding interface.

[0012] In one preferred embodiment, the data format type of the electricity meter includes a data format ID, and the length of the corresponding additional data, the normal filling interface, and the abnormal filling interface can be obtained based on the data format ID.

[0013] One preferred embodiment is that the electricity meter's test protocol information table includes the control code, data identifier, and data format ID for each protocol.

[0014] In one preferred embodiment, step S3 generates normal test messages and abnormal test messages according to the format corresponding to the protocol in the protocol information table under test, specifically as follows:

[0015] Based on the return values ​​of the normal and abnormal filling interfaces corresponding to the protocol in the protocol information table, determine whether there are any remaining normal or abnormal cases that need further testing.

[0016] If the return value of the normal or abnormal fill interface is TRUE, it means that there are other normal or abnormal cases that need to be tested. If the return value of the normal or abnormal fill interface is FALSE, it means that the protocol has completed all normal or abnormal tests.

[0017] One preferred embodiment, step S4, specifically includes:

[0018] The virtual message receiving module places the protocol request message from the master station request message generation module into the communication port driver buffer of the energy meter, simulating the energy meter receiving the protocol request message from the master station. The energy meter parses the protocol request message received in the communication port driver buffer and executes the protocol processing flow according to the parsed protocol request message. The processing flow obtains the data required by the protocol, sets the protocol data, or performs corresponding control on the energy meter according to the protocol type.

[0019] One preferred embodiment, step S5, specifically includes:

[0020] The statistical results of the electricity meter protocol operation include:

[0021] According to the normal test message of the normal filling interface, if the energy meter returns a normal response, the test is successful; if the energy meter returns an abnormal response, the test fails, and test failure statistics are performed.

[0022] Based on the abnormal test message of the abnormal filling interface, if the energy meter returns an abnormal response, the test is successful; if the energy meter returns a normal response, the test fails, and test failure statistics are performed.

[0023] The electricity meter checks the information table of protocols under test. If there are still protocols under test, repeat steps S2-S4 to complete the automatic test of all protocols in the information table of protocols under test.

[0024] In one preferred embodiment, after step S5, the method further includes:

[0025] Create an interface to clear the protocol information table and remove the protocol information table.

[0026] An electricity meter includes a memory and a processor; the memory stores a computer program that can run on the processor, and the processor, when executing the computer program, implements the automatic test method for full traversal of electricity meter protocol data.

[0027] The above-described technical solution of the present invention includes the following steps for the automatic full-traversal testing method of electricity meter protocol data: modeling the protocols supported by the electricity meter and defining the electricity meter data format types in the protocols; establishing a table of electricity meter protocols under test, and generating formal electricity meter protocol messages for each protocol in the table of protocols under test through the master station request message generation module according to the electricity meter protocol specifications; generating normal test messages and abnormal test messages according to the formats corresponding to the protocols in the table of protocols under test, and expecting normal and abnormal responses respectively; placing the protocol request messages generated by the master station request message generation module in the electricity meter communication port driver buffer, and executing the protocol processing flow according to the protocol request messages in the communication port driver buffer; statistically analyzing the electricity meter protocol operation results, and completing the automatic full-traversal testing of all protocols in the table of protocols under test. This invention significantly shortens the testing time, improves the testing effect, and solves the technical problem of how to accurately and quickly perform automatic full-traversal testing of electricity meter protocol data.

[0028] In this invention, multiple normal test messages and multiple abnormal test messages can be automatically constructed for the same protocol, and multiple normal condition tests and multiple abnormal condition tests can be performed on each protocol. It can automatically complete comprehensive normal and abnormal tests for all protocols under various conditions.

[0029] In this invention, the protocol information table under test can be configured, meaning it can be tailored for different application scenarios to meet specific needs. Attached Figure Description

[0040] See Figures 1-4 According to one aspect of the present invention, the present invention provides an automatic testing method for the full traversal of electricity meter protocol data, wherein the automatic testing method for the full traversal of electricity meter protocol data includes the following steps:

[0041] S1. Model the protocols supported by the electricity meter and define the data format type of the electricity meter in the protocol;

[0042] S2. Establish a table of protocols to be tested for electricity meters. The main station request message generation module generates formal electricity meter protocol messages for each protocol in the table of protocols to be tested according to the electricity meter protocol specifications.

[0043] S3. Based on the format corresponding to the protocol in the protocol information table, generate normal test messages and abnormal test messages respectively, and expect normal responses and abnormal responses respectively;

[0044] S4. The virtual message receiving module places the protocol request message generated by the master station request message generation module into the communication port driver buffer of the energy meter. The energy meter executes the protocol processing flow according to the protocol request message in the communication port driver buffer.

[0045] S5. Statistically analyze the operation results of the electricity meter protocol. Repeat steps S2-S4 to complete the full traversal automatic test of all protocols in the protocol information table under test.

[0046] Specifically, in this embodiment, the operation of the electricity meter by the protocol includes reading, setting, and operation. Each step has a corresponding format. Taking the 645 format as an example, the three types have their own control codes. Different data contents are distinguished by data identifiers. In addition to the data identifier, there is also data of a certain length, and the data length depends on the data format. The automatic test method for full traversal of electricity meter protocol data described in this invention is based on the understanding and mining of electricity meter protocol data. All protocols that the electricity meter can process are messages with a pre-defined format that the electricity meter can parse.

[0047] Specifically, in this embodiment, the protocols supported by the electricity meter are modeled. Each protocol of the electricity meter includes a control code, a data identifier, and additional data. All additional data has a certain format, defined as an additional data format. The format of the additional data includes the length of the additional data, a normal filling interface, and an abnormal filling interface. The length of the additional data can be obtained according to the type of the additional data format. At the same time, this invention implements a normal filling interface and an abnormal filling interface for each type of additional data format according to the format of the additional data. When the corresponding interface is NULL, it indicates that the corresponding filling interface does not exist. Abnormal filling is performed by filling illegal values ​​of the data format according to the type of additional data format to perform anomaly testing.

[0048] Specifically, in this embodiment, the data format type of the electricity meter includes a data format ID, and the length of the corresponding additional data, the normal filling interface, and the abnormal filling interface can be obtained according to the data format ID.

[0049] Specifically, in this embodiment, the energy meter test protocol information table includes the control code, data identifier, and data format ID for each protocol; the test protocol information table supports editing and generation by a host computer, and the test protocol information table is saved in the energy meter's non-volatile storage in the form of a file.

[0050] Specifically, in this embodiment, step S3 generates normal test messages and abnormal test messages according to the format corresponding to the protocol in the protocol information table under test, as follows:

[0051] Based on the return values ​​of the normal and abnormal filling interfaces corresponding to the protocol in the protocol information table, determine whether there are any remaining normal or abnormal cases that need further testing.

[0052] If the return value of the normal or abnormal fill interface is TRUE, it means that there are other normal or abnormal cases that need to be tested. If the return value of the normal or abnormal fill interface is FALSE, it means that the protocol has completed all normal or abnormal tests, thus achieving comprehensive coverage testing of all cases for each protocol.

[0053] Based on the protocol format in the protocol information table, normal test messages and abnormal test messages are generated according to their normal and abnormal filling interfaces, respectively, to test the protocol under normal and abnormal conditions. Each type of normal and abnormal filling interface can output different filling data each time it is called, according to its internal scheduling state machine, to perform various routine tests, special boundary condition tests, or abnormal tests. Multiple normal test messages and multiple abnormal test messages can be automatically constructed for the same protocol, and multiple normal and abnormal condition tests can be performed on each protocol, which can automatically complete comprehensive normal and abnormal tests for all protocols under various conditions.

[0054] Specifically, in this embodiment, step S4 is as follows: the virtual message receiving module places the protocol request message from the master station request message generation module into the energy meter communication port driver buffer, simulates the energy meter receiving the master station's protocol request message, the energy meter parses the protocol request message received in the communication port driver buffer, and executes the protocol processing flow according to the parsed protocol request message. The processing flow obtains the data required by the protocol, sets the protocol data, or performs corresponding control on the energy meter according to the protocol type.

[0055] Specifically, in this embodiment, step S5 is as follows:

[0056] The statistical results of the electricity meter protocol operation include:

[0057] According to the normal test message of the normal filling interface, if the energy meter returns a normal response, the test is successful; if the energy meter returns an abnormal response, the test fails, and test failure statistics are performed.

[0058] Based on the abnormal test message of the abnormal filling interface, if the energy meter returns an abnormal response, the test is successful; if the energy meter returns a normal response, the test fails, and test failure statistics are performed.

[0059] The electricity meter checks the information table of protocols under test. If there are still protocols under test, repeat steps S2-S4 to complete the automatic test of all protocols in the information table of protocols under test.

[0060] Specifically, in this embodiment, after step S5, the method further includes:

[0061] A protocol information table clearing interface is constructed to clear the protocol information table. Before the electricity meter leaves the factory, the clearing operation is performed to clear the protocol information table to be tested. In this way, the meter will not be tested for the above protocol when it leaves the factory, ensuring that the test is only carried out during the production and debugging process in the factory.

[0062] According to another aspect of the present invention, an electricity meter is provided, wherein the electricity meter includes: a memory and a processor; the memory stores a computer program that can run on the processor, and the processor, when executing the computer program, implements the automatic test method for full traversal of electricity meter protocol data.

[0063] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
