[0061] In this embodiment, the output port of the wireless module is also connected to the controller module, so as to effectively transmit the servo control instruction initiated by the wireless handheld unit to the controller module.

[0062] In addition, after receiving the instruction, the controller module will parse the instruction through the internal processing logic and convert the parsing result into corresponding control signals, which will then be sent to the target device to achieve precise control of the device.

[0063] In a possible implementation, the controller module includes a data processing submodule and a servo control submodule;

[0064] The input end of the data processing submodule is connected to the signal conditioning module, and the output end of the data processing submodule is connected to the wireless module;

[0067] The servo control submodule is used to receive a servo control instruction and send the servo control instruction to the servo system so that the servo motor executes the operation corresponding to the servo control instruction.

[0068] In this embodiment, the controller module is designed to include two main submodules, namely, a data processing submodule and a servo control submodule; the input port of the data processing submodule is directly connected to the signal conditioning module to receive the processed signal, and its output port is connected to the wireless module to send out the processed data; the input port of the servo control submodule is also connected to the wireless module to receive the control signal from the wireless module, and its output port is connected to the servo system to ensure that the control signal can be transmitted to the servo system;

[0069] The main function of the data processing submodule is to conduct in-depth analysis and processing of the operating signals received from the signal conditioning module, thereby extracting the operating data corresponding to the operating signals, which will serve as the operating reference data of the servo system under the test configuration;

[0070] The servo control submodule is responsible for receiving servo control instructions from the control system and sending these instructions to the servo system accurately, thereby ensuring that the servo motor can perform corresponding operating operations according to the received control instructions to achieve the expected control effect.

[0071] It should be noted that the design of the controller module also takes into account the scalability and maintainability of the system, so that each sub-module can be upgraded and replaced independently without affecting the stable operation of the entire system.

[0072] In actual applications, the controller module is connected to multiple sensor interfaces to monitor and collect various operating parameters in real time, such as temperature, pressure, speed, etc. These parameters, after being analyzed by the data processing submodule, can provide important basis for system optimization.

[0078] In this embodiment, the back-end test module receives the servo system test data, compares and interprets it with the test process and test parameters configured in advance by the tester, and writes the test results into a log and saves them in the database management module. Overall, efficient automated testing and recording of the servo system is achieved, which improves the objectivity of the test results, quality consistency, test safety, and test work efficiency.

[0079] Specifically, the back-end test module will conduct a detailed comparative analysis of the operating data collected from the wireless module and the corresponding test parameters in the pre-set test configuration to obtain accurate comparison results and ensure the accuracy and efficiency of data processing. Then, the back-end test module will conduct an in-depth error analysis on these comparison results, and obtain detailed test results about the test configuration by identifying and quantifying possible deviations.

[0080] The database management module is responsible for storing and managing these test results. The test results generated by the back-end test module are classified, organized, and securely stored in the database, which not only ensures the traceability and integrity of the data, but also provides a solid foundation for subsequent data analysis and decision-making.

[0081] The design of the database management module takes into account the security, stability and scalability of the data, ensuring efficient operation when faced with large amounts of data, and providing strong support for the continuous improvement and optimization of the wireless handheld unit.

Once an abnormality is detected, the back-end test module will automatically record the error information and take corresponding measures according to the preset fault handling procedures, such as resending instructions or notifying maintenance personnel to check. The real-time monitoring and rapid response mechanism greatly improves the stability and reliability of the entire test system, ensuring the continuity and accuracy of the test process.
