[0056] A method for reconstructing the health status of a controlled terminal throughout its life cycle provided by the present invention is now described.

[0057] Example 1

[0058] like Figure 1 As shown, the present invention provides a technical solution: a method for reconstructing the health status of a controlled terminal throughout its life cycle, wherein in step S1, the controller of the controlled terminal adaptive detection device is designed:

[0059] S1.1. Analyze the requirements of FTU for input signals under different working conditions and determine the type, amplitude range, frequency range and phase relationship of the analog signal;

[0060] S1.2. Select appropriate electronic components and design filtering, amplification, voltage stabilization and other circuits;

[0061] S1.3, conduct preliminary debugging, detect the output signal quality through testing instruments, and adjust parameters that do not meet the design requirements;

[0062] S1.4. Ensure the firmness of the aviation plug connection line with the FTU, and verify the signal transmission and response through overall testing;

[0063] S1.5. Optimize the detection method according to the actual detection scenario.

[0064] In this embodiment, the principle of non-power-off detection is studied, the requirements of FTU for input signals under different working conditions are deeply analyzed, and key parameters such as the type of analog signal (such as AC voltage, DC current, etc.), amplitude range, frequency range, and phase relationship are determined.

[0065] Design the circuit structure of the analog signal loop module and select appropriate electronic components according to the determined parameters. In the signal generation unit, select a high-precision, stable signal generator chip, and use peripheral resistors, capacitors and other components to adjust the signal parameters. In the signal conditioning unit, design appropriate filter circuits (such as low-pass filters, high-pass filters, etc.) to remove clutter interference in the signal, use amplifier chips to amplify or attenuate the signal to meet the output requirements, and use voltage stabilization circuits to ensure the stability of the signal voltage. The signal output unit is designed with a dedicated interface circuit so that it can be reliably connected to the FTU's aviation plug connection line and ensure the accuracy and anti-interference of signal transmission.

[0066] Make the hardware circuit board of the analog signal loop module and conduct preliminary debugging. Use oscilloscopes and other test instruments to test the quality of the output signal, check whether the amplitude, frequency, and phase of the signal meet the design requirements, as well as the stability and noise level of the signal. Make timely adjustments and optimizations to the problems found, such as replacing inappropriate components and adjusting circuit parameters.

[0067] The analog signal loop module is actually connected to the FTU's aviation plug connection line to establish a communication and data transmission channel. During the connection process, ensure the firmness and correctness of the connection to avoid poor contact or wrong connection. At the same time, the connected system is tested as a whole to verify whether the analog signal can be transmitted to the FTU normally and whether the FTU's response to the analog signal is as expected.

[0068] In actual applications, corresponding detection strategies and processes are formulated according to different detection scenarios and fault types. For example, for suspected FTU communication failures, a series of communication test signals with different frequencies and amplitudes can be sent, and the communication status indicator and feedback data of the FTU can be observed to determine whether the communication is normal. By continuously accumulating actual detection experience, optimizing detection methods and judgment criteria, the accuracy and efficiency of FTU fault diagnosis can be improved.

[0069] Example 2

[0070] like Figure 1-Figure 2 As shown, the present invention provides a technical solution: a method for reconstructing the health status of a controlled terminal throughout its life cycle, wherein the step S2, the adaptive unit module design and implementation:

[0071] S2.1. Establish FTU parameter database through investigation and statistics to understand the interface types and control logic of different manufacturers;

[0072] S2.2, adopt modular design ideas, develop intelligent control algorithms, and realize adaptive switching and analog docking;

[0073] S2.3, simulate the access conditions of different FTUs to test the function and compatibility of the adaptive module;

[0074] S2.4. Conduct function, performance and reliability tests to ensure the stability of the module in various environments;

[0075] S2.5. Improve the design of hardware and software based on test feedback.

[0076] In this embodiment, a comprehensive survey and statistics of mainstream FTUs on the market at this stage are conducted, and detailed parameter information of FTUs of different manufacturers is collected by consulting manufacturer product manuals, communicating with manufacturer technicians, and conducting field surveys, including but not limited to voltage levels (such as 110V, 220V, etc.), communication protocols (such as Modbus, IEC61850, etc.), interface types (such as RS485, Ethernet ports, etc.), and control logic (opening and closing control methods, protection setting values, etc.). The collected information is sorted and classified, and an FTU parameter database is established for subsequent design reference.

[0077] According to the collected parameter information, the hardware circuit design and software algorithm development of the adaptive unit module are carried out. In terms of hardware circuit, a modular design concept is adopted, and the parameter identification unit, adaptive switching unit and analog docking unit are designed as independent circuit board modules for easy debugging and maintenance. The parameter identification unit adopts high-precision voltage sensors and signal analysis chips, which can quickly and accurately detect key parameters such as the output voltage level of the aviation plug connected to the FTU. The adaptive switching unit is based on a high-performance microcontroller and is equipped with a self-developed intelligent switching algorithm. According to the information transmitted by the parameter identification unit, it controls components such as relay arrays or analog switches to achieve switching of different opening and closing relay configurations and working modes. The analog docking unit designs corresponding interface circuits and signal conversion circuits according to the interface types and communication protocol requirements of different FTUs, such as RS485 to RS232 converters, Ethernet interface chips, etc., to ensure accurate signal interaction with various FTUs.

[0078] In terms of software algorithm development, we focus on the research and development of intelligent control algorithms for adaptive switching units. This algorithm is based on advanced control theories such as fuzzy logic and neural networks, and can quickly make accurate decisions based on the input FTU parameter information to achieve seamless switching. At the same time, we develop corresponding communication protocol parsing software to ensure that the adaptive unit module can correctly understand and process the communication data of different FTUs. We jointly debug the designed hardware circuits and software algorithms, and test whether the various functions of the adaptive unit module are normal by simulating the access of FTUs from different manufacturers. We conduct in-depth analysis and troubleshooting of problems that arise, such as signal compatibility issues, excessive switching delays, etc., and solve them by optimizing hardware design and software algorithms.

[0079] The adaptive unit module is fully tested and verified, including functional testing, performance testing and reliability testing. The functional test mainly verifies whether the module's adaptive identification and simulated docking functions for different types of FTUs are normal. By connecting to a variety of actual FTU devices, the opening and closing operation test, communication test, etc. are carried out to check whether the module can accurately respond and perform corresponding actions. The performance test focuses on testing the module's switching speed, signal transmission accuracy and stability to ensure that it meets the requirements of actual applications. The reliability test uses long-term operation, high and low temperature environment tests, electromagnetic interference tests, etc. to test the module's working reliability and stability in various harsh environments. Only the adaptive unit modules that have passed rigorous testing and verification can be put into practical application.

[0080] Example 3

[0081] like Figure 1-Figure 3 As shown, the present invention provides a technical solution: a method for reconstructing the health status of a controlled terminal throughout its life cycle, wherein in step S3, the status monitoring and display system is designed:

[0082] S3.1. Design concise and clear combinations of diagrams and texts according to customer requirements;

[0083] S3.2, Humanized design, clear and reasonable main menu and submenus, and shortcut keys are set;

[0084] S3.3, develop data acquisition, processing, display driver and user interaction modules;

[0085] S3.4. Ensure smooth communication and data exchange among modules, and conduct comprehensive functional and compatibility tests;

[0086] S3.5. Fix problems based on test results and improve system stability and reliability;

[0087] In the step S4, status monitoring and display implementation:

[0088] S4.1. Install voltage, current and other sensors to collect the operating data of the controlled terminal in real time;

[0089] S4.2, transmit the data to the processor through the high-speed transmission line for analysis to determine the operating status of the equipment;

[0090] S4.3, real-time diagnosis of abnormal data, the system automatically gives fault handling suggestions to assist on-site personnel in making decisions;

[0091] S4.4. Analyze the health status indicators of equipment and predict the equipment life and performance change trends;

[0092] S4.5. The device status is displayed on the LCD screen, and important information is warned by eye-catching colors and sounds;

[0093] In the operation and management of step S5, in actual application:

[0094] S5.1. Carry out condition monitoring and data collection according to the designed steps;

[0095] S5.2. Timely handle faults diagnosed by the system;

[0096] S5.3. Maintain and manage equipment based on monitoring results;

[0097] S5.4. Accumulate experience through practical application and optimize operation procedures;

[0098] S5.5. Improve and upgrade system functions based on field feedback and technological development.

[0099] In this embodiment, determine the content and format that needs to be displayed on the LCD screen. Communicate fully with power operation and maintenance experts and on-site staff to understand their needs and focus on equipment status information in actual work. In addition to the real-time operating status parameters, fault information, opening and closing command execution status and health status assessment indicators of the controlled terminal mentioned above, other relevant information can be added according to actual conditions, such as historical maintenance records of the equipment, surrounding environmental parameters (such as temperature, humidity, etc.). For the display format, design a concise and clear combination of charts, graphics and text to make the information easy to read and understand.

[0100] Design the display interface and operation interface of the LCD screen. Adopt a humanized interface design concept, taking into account the operator's usage habits and visual experience. The operation interface is designed as a menu structure, divided into a main menu and submenus. The main menu includes main function options such as equipment status monitoring, fault diagnosis, parameter setting, and historical record query. The submenus are further expanded according to the main menu options to provide specific operations and viewing content. For example, in the equipment status monitoring submenu, you can view detailed data and charts of each real-time parameter; in the fault diagnosis submenu, a detailed analysis report and handling suggestions of the fault are displayed. At the same time, in order to facilitate the operator's quick operation, set some shortcut keys and quick function entrances, such as one-click switching to the key parameter page, one-click start fault diagnosis, etc. In the interface design process, pay attention to color matching and font selection to ensure clear and beautiful display and improve user experience.

[0101] Write software programs for status monitoring and display. The software program mainly includes data acquisition module, data processing module, display driver module and user interaction module. The data acquisition module is responsible for communicating with various sensors installed on the controlled terminal, collecting the operation data of the equipment in real time, and performing preliminary verification and sorting of the data. The data processing module uses data analysis algorithms to analyze and process the collected data, extract useful information, such as calculating the health status indicators of the equipment, judging whether there are abnormalities, etc. The display driver module generates corresponding display content based on the processed data and the user's operation instructions, and drives the LCD screen to display. The user interaction module is responsible for processing the operation instructions issued by the operator through input devices such as buttons and touch screens to realize the interaction function with the user. In the process of software program writing, we pay attention to the optimization and reliability of the code, and use multi-threaded programming, caching technology and other means to improve the operation efficiency and response speed of the program.

[0102] Integrate and debug the status monitoring and display system with other parts of the controlled terminal adaptive detection device. During the integration process, ensure that the communication between the modules is smooth and the data interaction is accurate. Perform comprehensive debugging and testing on the entire system, including functional testing, compatibility testing, and stability testing. Functional testing verifies whether the various functions of the system meet the design requirements, such as whether the data collection is accurate, whether the display is normal, and whether the fault diagnosis is accurate. The compatibility test mainly checks the compatibility of the system with different models of controlled terminals and other related equipment. The stability test runs the system for a long time to observe whether there are abnormal conditions such as freezes and data loss. Problems found during the test are repaired and optimized in a timely manner to ensure that the system can operate stably and reliably, provide accurate and real-time equipment status information to power operation and maintenance personnel, and realize effective monitoring and management of the health status of the controlled terminal throughout its life cycle.

[0103] In actual applications, by operating in accordance with the above implementation method, it is possible to reconstruct and monitor the health status of the controlled terminal throughout its life cycle, detect faults in a timely manner and take corresponding measures to ensure the safe and stable operation of the power system.

[0104] In order to make the operation simple and easy for the on-site personnel, a humanized operation interface is designed. The interface layout is clear and reasonable, and the menu-based operation mode is adopted. The operator can quickly switch to view different information pages through simple key operations. At the same time, for important information and alarm prompts, eye-catching colors and sounds are used to remind, ensuring that the on-site personnel can notice the abnormal situation of the equipment in time.

[0105] In terms of status monitoring, the operating data of the equipment is collected in real time through sensors installed in various key parts of the controlled terminal. These sensors include voltage sensors, current sensors, temperature sensors, vibration sensors, etc., which can comprehensively monitor the electrical performance and mechanical status of the equipment. The collected data is transmitted to the processor of the monitoring system through high-speed data transmission lines. The processor uses advanced data analysis algorithms to process and analyze the data and judge in real time whether the operating status of the equipment is normal. When abnormal data is found, the system will automatically perform fault diagnosis and display the diagnosis results on the LCD screen. At the same time, corresponding processing suggestions are given to help on-site personnel quickly and accurately locate and solve problems, thereby realizing real-time monitoring and effective management of the health status of the controlled terminal throughout its life cycle.

[0106] The present invention,

[0107] The design of the controller of the controlled terminal adaptive detection device is first based on the principle of non-stop detection, and deeply analyzes the requirements of FTU for input signals under different working conditions, and clarifies the key parameters such as the type, amplitude range, frequency range and phase relationship of the analog signal. Subsequently, the circuit structure of the analog signal loop module is designed, and the accurate and stable signal generator chip is selected, and the quality and stability of the signal are ensured through filtering and amplification circuits. Next, the hardware circuit board is made, and debugged through test instruments such as oscilloscopes to verify whether the amplitude, frequency and phase of the signal meet the requirements, and optimize the design to solve the detected problems. When making the actual connection with the FTU's aviation plug connection line, ensure the firmness and reliability of the connection, and verify the accuracy of signal transmission and the response of the FTU through overall testing.

[0108] When designing the adaptive unit module, it is necessary to first investigate the mainstream FTUs on the market, collect detailed parameter information, such as voltage level, communication protocol and interface type, and establish a parameter database. Based on this information, the hardware circuit and software algorithm are developed, and the parameter identification unit, adaptive switching unit and simulation docking unit are modularly designed. The adaptive switching unit realizes seamless switching for different FTUs through intelligent control algorithms. Communication protocol parsing software is developed to ensure the correct processing of different FTU data. In the joint debugging process, the module functions and signal compatibility are tested by simulating the access of FTUs from different manufacturers, and the problems found are solved.

[0109] The design of the status monitoring and display system needs to first determine the display content and format on the LCD screen, and make the equipment status information easy to read through a concise and clear interface design. The operation interface adopts a menu-based structure for easy navigation and use. The software program includes data acquisition, processing, display driver and user interaction modules to ensure that the data collected from the sensor is accurately displayed after analysis. Through the collaborative work of these modules, real-time monitoring of equipment status and fault diagnosis functions are provided. During the system design process, attention is paid to code optimization to improve the operating efficiency and reliability of the program.

[0110] Integrate the status monitoring and display system with other parts of the adaptive detection device to ensure smooth communication and data exchange between modules. Perform comprehensive functional tests, compatibility tests, and stability tests to verify the performance of the entire system under different environments and conditions. Functional tests ensure that the system can accurately collect data and diagnose faults, compatibility tests verify compatibility with different models of controlled terminals, and stability tests verify the reliability of the system through long-term operation. Promptly repair problems found in the test and optimize the system design to ensure stable operation.

[0111] In practical applications, the above method can be used to monitor and reconstruct the health status of the controlled terminal throughout its life cycle, ensuring that the real-time status information of the equipment is effectively managed. The system can detect faults in a timely manner, provide treatment suggestions, and help operation and maintenance personnel take measures to ensure the safe and stable operation of the power system. Continuously accumulate operating experience, optimize detection processes and judgment criteria, improve the accuracy and efficiency of fault diagnosis, and continuously improve system functions based on on-site feedback to enhance the automation and intelligence level of power operation and maintenance.
