The test report generation module generates a test report based on the interchangeability analysis results, and uses a visual interface for statistics and query. The test report includes test results, test data, test cases, test scenarios, test progress and test suggestions.

[0016] In the above embodiment, the data acquisition server simulates the process of sending requests and receiving responses by the electricity consumption information collection terminal through a virtual machine. The simulation test executor uses a protocol stack and a communication framework to simulate a real test scenario. The network device simulates and accesses the network environment through a virtual switch and a physical switch, and implements network configuration and management through a software-defined network SDN. The virtual switch connects virtual machines by creating a logical subnet virtual machine, and builds a simulated network environment according to the IP address, subnet mask and gateway parameters of the electricity consumption information collection terminal.

When sending a request, the server simulates multiple power consumption information collection terminals, each terminal corresponds to a virtual machine, and different request types and request frequencies can be simulated by configuring the parameters of each virtual machine when sending a request. The simulation test executor runs on the virtualized test platform, simulates the establishment of a communication connection, receives a request from the data acquisition server and returns a response. In the simulation executor, by configuring the parameters of each virtual machine, different response time, throughput and other indicators are simulated to evaluate the performance of the communication interface.

[0048] The hybrid distribution network algorithm model was used as the experimental group A, and the hybrid distribution algorithm was used as the experimental group B for comparative experiments. The two algorithms were used to test the interchangeability of ten different power consumption information collection terminal communication interfaces, and the test result data was recorded as input. By processing the test result data, extracting features and modeling, the prediction results of the experimental groups A and B were obtained, and the processing speed of each communication interface was recorded in Table 2.

[0050] According to the results in Table 2, it can be seen that the processing speed of the experimental group A using the hybrid distribution network algorithm model is faster than that of the experimental group B using the hybrid distribution algorithm.

[0051] In the above embodiment, the visualization interface obtains the interchangeability analysis results based on the data wireless transmission interface, and uses a correlation data model to implement multi-dimensional data correlation analysis. The correlation data model uses interactive charts, heat maps and dashboards to achieve real-time monitoring of data trends, relationships and change patterns. The visualization interface implements test report index query by building a search engine, and uses a Token user identity authentication mechanism to verify the identity of the accessing user.

[0052] In a specific embodiment, the visualization interface is an important part of the test system, and its main function is to visualize the test result data to the user, so that the user can intuitively understand the characteristics, trends and changing laws of the test data. The interchangeability analysis results are obtained through the wireless sensor network, and then the data is preprocessed, including data deduplication, data cleaning, data formatting, etc. The relationship between different test indicators is modeled using the correlation data model to achieve multi-dimensional data correlation analysis. At the same time, the correlation analysis results are displayed in interactive charts, heat maps and dashboards, so that users can intuitively understand the trends, relationships and changing laws of the data. The Token user identity authentication mechanism is used to verify the identity of the accessing user to improve the security of information access. The user needs to enter the login information to obtain the access token, and then use the token to access the system resources. The system will verify the validity of the token, and only the verified user can access the system resources. Using interactive charts, heat maps and dashboards and other visualization means, real-time monitoring functions are provided, which can monitor the characteristics, trends and changing laws of the test data in real time, and feedback the monitoring results to the user in a timely manner.

[0053] Through the above implementation methods, the visual interface can provide users with a simple, intuitive, and easy-to-operate interface, and can allow users to quickly understand the characteristics, trends, and changing rules of test results through visualization, thereby assisting users in making more accurate test decisions. At the same time, the identity authentication mechanism can also be used to protect the privacy of users and the security of sensitive information.

For example, merging the above method steps so as to perform substantially the same functions in substantially the same manner to achieve substantially the same results is within the scope of the present invention. Therefore, the scope of the present invention is limited only by the appended claims.
