Description

Technical Field

[0002] As the functions of State Grid electricity meters continue to upgrade, the number of test functions for current concentrators or meter equipment is gradually increasing. At the same time, because State Grid electricity meters do not support network communication and can only communicate via serial ports, there are still challenges in building a network communication system. Therefore, in functional testing scenarios for various electricity meters, the workload of manual testing is increasing, and the testing cycle is becoming longer.

[0003] Furthermore, existing automated testing platforms for hardware devices primarily rely on host computers, requiring testers to manually send command codes via host computer software to perform functional tests on the devices. This testing method has the following drawbacks:

[0004] 1. Due to the limitations of manual operation, the testing cycle is relatively long;

[0005] 2. The functional testing coverage is limited, and only the existing testing solutions on the host computer can be used;

[0006] 3. The test involves a large number of hardware devices, which lack unified management and result in insufficient utilization of hardware resources;

[0064] To explain in detail the technical principles, specific implementable solutions, possible application scenarios, and achievable objectives and effects of the present invention, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. It is understood that the embodiments described herein and the embodiments shown in the accompanying drawings are only used to more clearly illustrate the technical solutions of the present invention, and are therefore only examples intended to explain the present invention, and should not be construed as limiting the present invention. It should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0065] This invention utilizes a specially designed distributed automated testing system architecture, enabling the management of multiple testing clients through a single testing cloud platform. These clients then control meters and programmable power supplies using different State Grid protocols, thus achieving distributed automated functional testing of State Grid meters. This solves the problems of low efficiency, long testing cycles, and limited testing scope in existing State Grid meter testing due to their inability to communicate externally.

[0066] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0067] Figure 1 This is a schematic diagram of the distributed automatic testing system architecture for State Grid electricity meters as described in this embodiment of the invention.

[0068] Figure 2 This is a timing diagram for distributed automatic testing in a specific embodiment of the present invention.

[0069] This invention provides a distributed automatic testing method for State Grid electricity meters, based on... Figure 1 The distributed automated testing system architecture shown is implemented.

[0070] like Figure 1 As shown, the distributed automatic testing system architecture for State Grid meters includes a test cloud platform and two or more test client networks; each test client network includes a test client, at least one programmable power supply, and two or more State Grid meters; in one test client network, the test client is wirelessly connected to the test cloud platform, and the programmable power supply and State Grid meters are respectively connected to the test client via serial ports, with each State Grid meter connected to one programmable power supply.

[0071] In each test client network, the test client, acting as the host computer, can control the electricity meters and programmable power supplies of different State Grid protocols (State Grid 698 protocol and State Grid 645 protocol) in its network. Based on the test tasks issued by the test cloud platform, it can perform functional tests step by step on the selected test objects according to the test case requirements and obtain the test results.

[0072] Specifically, each test client network can contain multiple State Grid meters, and a single test cloud platform can manage multiple test clients. Therefore, the test cloud platform enables simultaneous functional testing and management of hundreds of State Grid meters under test.

[0073] Based on the above-described distributed automatic testing system architecture, the distributed automatic testing method for State Grid meters provided in this embodiment includes at least the following steps:

[0074] S1: The test cloud platform pre-stores two or more test scripts, and each script is encapsulated to obtain encapsulation keywords that can drive the corresponding test scripts to execute automatically.

[0075] Here, it is supported to pre-import user-defined test scripts and / or existing regular / common test scripts into the test cloud platform for storage and management. One test script corresponds to a control command for the electricity meter, such as calling a specific meter parameter. As a specific example, one pre-stored test script in the test cloud platform, after being executed by the host computer, can "read the electricity meter time"; another test script, after being executed by the host computer, can "control the programmable power supply to start according to specified power start parameters (such as voltage 220V, current 5A)".

[0076] The test cloud platform in this embodiment can encapsulate each test script into a corresponding keyword. This encapsulated keyword can then directly drive the automatic execution of the corresponding test script. For example, the test cloud platform encapsulates the key control instruction "read meter time" in a test script into an encapsulated keyword, such as "read meter time"; it also encapsulates a key control instruction in another test script into the encapsulated keyword "power control". Therefore, by calling the "encapsulated keyword" within the test cloud platform, the corresponding test script can be invoked and automatically executed.

[0077] It is important to note that existing conventional keyword-driven frameworks are primarily based on the Robot Framework. However, the Robot Framework lacks a web-based version, making it unsuitable for cloud platforms. This invention specifically redevelops and implements the underlying keyword-driven framework using Python's pytest framework. Then, it uses Django Framework + Vue 3.0 + MySQL for front-end and back-end integration, thereby enabling the implementation of a keyword-driven framework on a web platform. This allows for the encapsulation of keywords to automatically drive the corresponding test programs.

[0078] S2: Create a test case through the test cloud platform;

[0079] Users can write custom test cases in the test cloud platform to perform specified functional tests on meters with specified numbers.

[0080] Specifically, this step includes the following sub-steps:

[0081] A1. The test cloud platform extracts keywords based on the steps described by the user;

[0082] A2. The test cloud platform displays encapsulated keywords that match the extracted keywords;

[0083] Here, the step descriptions correspond to the control instructions that the user expects to execute. Specifically, the step descriptions can be in plain language or technical terminology. The test cloud platform will perform feature analysis on the step descriptions entered by the user, extract their keywords, and match them with stored "encapsulation keywords," providing the user with all matching "encapsulation keywords" to choose from.

[0084] As can be seen, the test cloud platform in this embodiment can provide accurate automatic proofreading, identification, and matching support during the user's test case writing process. This helps simplify the writing process and improve the efficiency of test case writing.

[0085] A3. Based on the user-selected encapsulation keywords and operation objects, as well as the user-input test data and expected results, generate the corresponding test steps;

[0086] The operation object refers to the object operated by the control command of this test step. For example, "power supply device serial port" or "698 protocol meter".

[0087] The test data corresponds to the specific data executed by the control command of this test step. For example, "input the specified power start parameters (e.g., voltage 220V, current 5A)" or "read the electricity data for a specific time period from the meter." It should be noted that the test script, called by encapsulated keywords, clearly defines "what to do"; while the test data clearly defines "how to do it."

[0088] The expected result refers to the ideal result to be obtained after the control command for this test step is executed. This parameter is optional; if configured, the comparison between the expected result and the actual result will be reflected in the test results for this test.

[0089] A4. Obtain the test cases obtained by combining each test step in sequence, and store the test cases in the test case library;

[0090] Specifically, users configure the generated test steps sequentially on the test cloud platform, and the tests will be automatically combined according to the configuration order to obtain a complete custom test case.

[0091] As can be seen, when users write the required automated test cases on the test cloud platform, they only need to enter the relevant step descriptions, select the target encapsulation keywords and operation objects, and enter the test data and expected results (optional) to automatically generate the corresponding test steps.

[0092] As a concrete example, write a test case for "reading the current time of the electricity meter", including the following steps:

[0093] 1. Go to Test Case Management and click "New";

[0094] 2. Enter the test case title, priority, project, and module;

[0095] 3. Add test step 1, adding the step description "Power on, set voltage 220V"; then, the test platform will automatically identify, analyze and match the added step description, and display the matching package keywords; the user selects the package keyword "power control", selects the operation object "power device serial port", and then enters the test data "power start parameters (voltage 220V, current 5A)"; thus completing the configuration of test step 1;

[0096] 4. Add test step 2, adding the step description "Read State Grid meter time"; then, the test platform displays the matching encapsulation keywords; the user selects the encapsulation keyword "698 protocol meter control", selects the operation object "698 protocol meter", enters the test data "Send meter communication command Read Time", and enters the expected result "2025-04-01 12:20:00"; complete the configuration of test step 2;

[0097] 5. Click "Submit", and the testing system will automatically generate a test case for "reading the current time of the electricity meter".

[0098] As shown above, users can easily and quickly write an automated test case by performing just a few simple operations on the testing cloud platform. This significantly simplifies the test case writing process and improves efficiency during testing.

[0099] S3: Create a test task and select its corresponding test object, test cases, and test environment; the test environment includes a programmable power supply; the test object is the meter number of the State Grid meter under test;

[0100] Here, the test object is the target test object for the entire test task, such as the electricity meter with the meter number "041011011".

[0101] The test environment configuration specifies which environment the currently created test task targets for automatic testing of the test object. In this embodiment, the test environment corresponds to a programmable power supply or a concentrator (the electricity meter can be connected to the test client via the concentrator). By identifying the "test environment" parameter in the test task, the test cloud platform can determine which test client network the test task should be distributed to for execution.

[0102] In a specific example, the test cloud platform provides the following options for the test environment: "Programmable power supply cabinet 1, programmable power supply cabinet 2... programmable power supply cabinet N, gateway 1, gateway 2... gateway N".

[0103] In some specific implementations, creating a test task includes the following sub-steps:

[0104] B1. Create a test project, add the project name and authorized users;

[0105] As a specific example, add a project named "698 Protocol Shandong State Grid Project", add a project member named "Zhang San", associate the project name with the personnel with project permissions, and assign "Zhang San" project permissions;

[0106] B2. Create a test task under the test project and add a test task name;

[0107] As a specific example, add a test task named "698 Protocol Shandong State Grid 0410 Version Test".

[0108] B3. Select the test object, test cases, and test environment corresponding to the test task;

[0109] As a specific example, select the target test case in the test case library, add the test object as the meter with the meter number "041011011", and select the corresponding test environment as "programmable power cabinet 1".

[0110] S4: The test cloud platform distributes the test task to the corresponding test client based on the test environment selected in the test task;

[0111] Here, combined with Figure 2 To understand this, after the user starts the test task in the test cloud platform, the test cloud platform begins to execute the test task. First, based on the selected test environment, the corresponding test client network is identified, and then the test task is sent to the test client in that test client network as the host computer.

[0112] S5: The test client uses the corresponding test cases to test the corresponding test objects based on the received test tasks.

[0113] Here, combined with Figure 2 Once the test client receives the test task, it will use the configured test cases to test the "test object" in the test environment, based on the test environment configured therein.

[0114] As a specific example, the test client will use the "test cases" configured in the test task to automatically perform the corresponding functional tests on the meter with meter number "041011011" in "programmable power cabinet 1".

[0115] In some specific implementations, combined with Figure 2 To understand this, the use of corresponding test cases to test the corresponding test object includes two aspects of control:

[0116] (1) Power Control: The test client controls the power supply corresponding to the "test environment" in the test task according to the test cases in the test task. For example, it controls the power supply to start with a voltage of 220V and a current of 5A. Through power control, power can be supplied to the test object, ensuring the smooth conduct of functional testing of the test object;

[0117] (2) Meter Control: The test client controls the test objects in the test task according to the test cases in the test task. For example, it reads the current time of the meter that uses the 698 protocol and has the meter number 041011011.

[0118] In some other specific embodiments, the distributed automated testing method further includes:

[0119] S6: After the test is completed, the test client obtains the corresponding test results and sends them to the test cloud platform; the test results include test results and log records; the test cloud platform generates a test report for the corresponding test task based on the test results; or

[0120] After the test is completed, the test client obtains the corresponding test results and generates a test report for the corresponding test task based on the test results.

[0121] Preferably, whether the test report is generated by the test client or the test cloud platform, it supports displaying the test report in a visual format.

[0122] In other words, the test report corresponding to the test task can be configured to be generated directly by the test client based on its measured test results; or it can be configured to have the test client return the test results to the test cloud platform in real time, and the test cloud platform will then generate the report. The specific configuration can be flexibly adjusted according to actual needs or resource requirements.

[0123] In some other specific embodiments, the distributed automated testing method further includes:

[0124] S7: View the status of each test client through the test cloud platform. The status includes the test task execution status (testing, standby, test completed) and the network connection architecture of each test client.

[0125] As described above, the distributed automatic testing method for State Grid meters provided in this embodiment, targeting meters using the State Grid 698 and State Grid 645 protocols, utilizes a specially configured test cloud platform. This platform enables efficient and convenient creation of custom test cases driven by keywords. It allows for the creation of test tasks with selected test environments, test objects, and test cases, and automatically identifies the destination of test tasks, distributing them to test clients within the corresponding test client network. Through this specially constructed distributed test client network, automated functional testing of the meters is achieved under the management and control of the test cloud platform. Therefore, this embodiment allows for the management and control of multiple test clients through a single test cloud platform, while a single test client can simultaneously control multiple meters and programmable power supplies using different protocols. This enables a distributed automatic testing solution that simultaneously manages hundreds of meters under test for automated functional testing via the test cloud platform, offering advantages such as high testing efficiency, short cycle time, wide testing scope, and high degree of automation.

[0126] Figure 3 This is a business logic block diagram of a distributed automatic testing system for State Grid electricity meters, provided as another embodiment of the present invention.

[0127] Another embodiment of the present invention, based on the previous embodiment, provides a distributed automatic testing system for State Grid electricity meters.

[0142] Create a test project, and add the project name and authorized users.

[0176] As described above, the distributed automatic testing system for State Grid meters provided in this embodiment is specifically designed for meters using the State Grid 698 and State Grid 645 protocols. It features a distributed automatic testing system architecture comprised of a test cloud platform and multiple test client networks. The test cloud platform can wirelessly communicate with the test clients acting as host computers in the multiple test client networks. Each test client in the network directly communicates with multiple meters and programmable power supplies under test using the proprietary State Grid standard communication protocol. Based on this distributed automatic testing system architecture, multiple test clients can be managed and controlled through a single test cloud platform. These test clients then control meters and programmable power supplies using different State Grid protocols, enabling distributed automated functional testing of State Grid meters. This system offers advantages such as high testing efficiency, short cycle time, wide testing range, and high degree of automation.
