Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of intelligent monitoring and diagnosis, and in particular to a method and system for self-diagnosis and emergency treatment of faults in a calibration line of an electric energy meter. Background Art
[0002] With the development of smart grids and the increasing demand for the application of electric energy meters, the verification and management technology of electric energy meters has gradually developed towards automation and intelligence. The traditional verification method of electric energy meters mainly relies on manual operation, which is not only inefficient, but also easily affected by human factors, resulting in inaccurate and unstable verification results. In recent years, with the rapid development of information technology, automation control technology and the Internet of Things, the verification and management of electric energy meters have begun to shift towards a more efficient and scientific direction. The existing verification systems mostly achieve comprehensive control of the verification process through the combination of software and hardware. This change has significantly improved the accuracy and efficiency of the verification. However, in actual applications, there are still widespread problems such as insufficient real-time monitoring capabilities, lack of fault diagnosis functions, and imperfect emergency response mechanisms, which hinder the further improvement and application of electric energy meter verification technology.
[0003] In view of the shortcomings of the existing technology, it can be seen that the defects of the current electric energy meter calibration line in fault self-diagnosis and emergency treatment are particularly prominent. When a fault occurs, most systems can only rely on manual experience for troubleshooting, missing the best time to deal with it, resulting in an extended maintenance cycle. At the same time, the traditional calibration line lacks effective intelligent monitoring means, cannot collect and analyze key data in real time, and the feedback mechanism is inflexible, resulting in the inability to timely discover potential fault hazards. In response to these problems, the electric energy meter calibration line fault self-diagnosis and emergency treatment method invented by us, with its real-time monitoring and intelligent analysis capabilities, can effectively improve the system's response speed and processing efficiency to faults, thereby greatly reducing the economic losses caused by faults. In addition, this technical solution can improve the intelligence level of the entire calibration process through automatic data interaction and information management, and achieve more efficient calibration operations and fault management, which has important practical application value. Summary of the invention

[0042] S1: Use the line debugging software to monitor the operating status of the electric energy meter calibration line in real time and collect the working parameters of each unit.
[0043] Furthermore, the system automatically performs self-checks to confirm that all sensors, processing units, and actuators are in normal condition and provides feedback on the results in real time;
[0044] The line debugging software interacts with each monitoring unit through ECM to realize data collection. ECM processes data locally and supports multi-channel parallel technology. It simultaneously monitors detection point parameters including temperature, current, and power supply status. The system dynamically adjusts the monitoring threshold based on data feedback to adapt to environmental changes and equipment aging, ensuring the sensitivity and accuracy of monitoring.
[0045] It should be noted that the system sets fixed time intervals to automatically upload the status data of each unit to the central database, realize the periodic recording and storage of data, and regularly synchronize and update historical data and monitoring results through the interface with the cloud platform;
[0046] Once a fault or abnormal indicator is detected, the system will quickly disconnect the power supply of the faulty unit according to the preset response strategy, automatically record detailed information about the fault, including the type of fault, time of occurrence, and duration, and push it to relevant maintenance personnel in real time for timely processing and repair.
[0047] S2: Execute the fault self-diagnosis program, use the PLC and self-diagnosis function to automatically identify and judge line-level faults, and generate a fault report.
[0048] Furthermore, after the system is started, the PLC performs a self-check and reads the status of each sensor and module;
[0049] Monitor the real-time data of the core module, calculate the real-time temperature and real-time humidity, monitor the module status S to be 1 if normal, 0 if faulty, and update in real time:
[0050]
[0051] Among them, D temp is the real-time temperature reading, T low ,T high are the lower and upper limits of temperature, respectively, and D humidity is the real-time humidity reading, H low (t),H high (t) are the lower and upper limits of humidity, respectively;
[0052] The dynamic threshold is defined as:
[0053] T low (t) = T base -k1·sin(wt+φ)
[0054] T high (t) = T base -k2·sin(wt+φ)
[0055] Among them, k1 and k2 are the amplitude factors of temperature fluctuation, w is the frequency of temperature change, φ is the phase of temperature change, and the lower and upper limits of humidity can be obtained by the same logic; at the same time, the number of unqualified items U and the unqualified rate R in N times of verification are calculated:
[0056]
[0057] For online monitoring of clock accuracy, the station compares with the remote clock server and issues an alarm if the limit is exceeded. Based on the returned signal status, the system records whether the connection is successful each time an attempt is made to connect, and counts the number of unsuccessful connection attempts.

[0081] S4: When a fault occurs, the system automatically guides the operator to perform emergency processing according to the preset emergency processing steps, and records all fault and processing data for subsequent tracing.
[0082] Furthermore, when the temperature exceeds the set range, the system immediately triggers a temperature alarm, records abnormal parameters and generates a fault report. After the alarm, the system continues to collect temperature data and feeds it back to the control system, observes the temperature trend, checks the working status of the heat dissipation or heating equipment, and ensures normal operation. If it detects that the temperature quickly returns to the normal range, the system can automatically restart the module. If the temperature continues to be abnormal, the operator is instructed to perform manual maintenance, adjust the operating conditions or replace the faulty component;
[0083] When the humidity exceeds the set range, the humidity alarm is triggered, the humidity parameters are recorded and a fault report is generated. The humidity changes are monitored in real time, the trend of abnormal humidity is analyzed, and the ventilation, humidification or dehumidification equipment is checked to ensure the normal operation of the equipment. When the humidity returns to the normal range, the humidity monitoring system is automatically restarted. If the abnormality persists, the operator is guided to perform manual inspection and repair;
