Traditional building intercom system testing relies on manual simulation of calling, unlocking, alarming and other scenarios, which is inefficient and prone to missed detections. In addition, multi-device linkage testing requires manual point-by-point debugging, and the compatibility verification cost is high. To solve this problem, an automated testing device has appeared on the market, but the automated testing device still has the following deficiencies during use: 1. Most automated testing equipment is a single functional module and lacks full-link closed-loop testing capabilities; 2.

According to the preset test process and strategy, it sends instructions to the stimulus generation module to generate stimulus signals, controls the acquisition frequency and acquisition duration parameters of the data acquisition module, analyzes and processes the collected data, and stores the test results in the storage module.

[0023] S6: The control module transmits the real-time processed data to the display and operation module, which is displayed to the operator in the form of numbers and waveforms on the interface, making it convenient for the operator to monitor the test process in real time. At the same time, the control module stores the original data and processed data in the storage module;

[0024] S7: At the same time, the AI ​​algorithm engine performs automatic cycle testing, linkage testing, and stress testing, and determines whether the device under test has a fault based on vibration sensor and current waveform analysis. If so, a fault location report is generated. If not, a pass report is generated and transmitted to the control module. During the test process, the fault prediction model automatically increases the test frequency of high-risk scenarios based on historical fault data, and analyzes the test data through algorithms to provide early warning of equipment aging trends and assist in formulating maintenance plans.

[0025] S8: When the preset test end condition is reached, the control module sends a stop instruction to the stimulus generation module to stop the output of the stimulus signal, and at the same time controls the data acquisition module to stop data acquisition;

[0026] S9: The control module comprehensively analyzes and processes the test data in the storage module and generates a detailed test result report. The report includes test items, test parameters, test data, performance index evaluation results, and a conclusion on whether the test is qualified.

[0027] S10: The control module transmits the test result report and the report generated by the AI ​​algorithm engine to the display and operation module. The operator can view the report content on the interface and print and export it as needed. The test result report is automatically sent to the remote server or the mailbox of the relevant manager through the communication module to realize the sharing and remote management of the test results.

[0028] Preferably, in S7, the fault prediction model in the AI ​​algorithm engine needs to be trained and verified before use, and the specific logical steps are as follows:

[0029] S701: Perform data cleaning and feature engineering operations on the data collected by the data acquisition module, delete outliers, and extract features of vibration frequency, current waveform, and corresponding delay;

[0030] S702: Divide the collected data set into a 70% training set, a 20% validation set, and a 10% test set;

[0031] S703: Select the fault prediction model of the LSTM+Attention mechanism as the training model;

[0033] S705: Label the training indicators. If they meet the requirements, directly deploy the model to the algorithm engine. Otherwise, use the regularization coefficient to adjust the hyperparameters and continue to iterate the training and verification operations.

The specific logical steps are as follows: S701: Perform data cleaning and feature engineering operations on the data collected by the data acquisition module, delete outliers, and extract features of vibration frequency, current waveform, and corresponding delay; S702: Divide the collected data set into a 70% training set, a 20% validation set, and a 10% test set; S703: Select the fault prediction model of the LSTM+Attention mechanism as the training model; S704: Using the training set and the loss function to train the selected model, and using the validation set to train the model; S705: Label the training indicators. If they meet the requirements, directly deploy the model to the algorithm engine. Otherwise, use the regularization coefficient to adjust the hyperparameters and continue to iterate the training and verification operations.
