[0021] Further implementation methods are as follows: Step 1: Integration of intelligent alarm and computer monitoring system The intelligent alarm system of the hydropower station deploys the IMC6 system on the intelligent alarm server to achieve two-way communication with the running IMC3 monitoring system to complete the import and analysis of measurement point data. On this basis, the system integrates data collection, analysis and linkage functions to provide core support for intelligent monitoring and alarm management: Data integration: IMC6 and IMC3 systems achieve efficient communication, collect measurement point data in the production control area in real time, complete data validity verification and filter invalid data; Data supply and sharing: The data of the intelligent monitoring panel is output to the three-zone data platform to realize the display and linkage support of alarm information and status analysis results.

[0022] Step 2: Background data processing and equipment status analysis The system background uses intelligent algorithms to achieve in-depth analysis and trend prediction of equipment operating status, providing support for alarm accuracy and rapid emergency response: Real-time data storage and historical data import: The background collects and stores real-time data from the production control area, and supports the import and analysis of historical data from various systems; Intelligent threshold learning: Based on the equipment model, it automatically learns historical data, forms alarm thresholds under different working conditions, and dynamically corrects them to improve the accuracy and intelligence level of alarms; Trend analysis and prediction: Combined with equipment operating parameters, vertical and horizontal trend analysis is carried out. When the status parameters deviate significantly from the set value or historical average level, an alarm is generated and recorded.

[0023] Step 3: Intelligent screen inspection and report automation functions Intelligent screen inspection and reporting functions provide efficient and convenient support for operation and maintenance: Intelligent screen inspection: Automatically inspect the operating parameters of the electromechanical equipment of the entire station every two hours, record and analyze the data, and generate Excel documents for easy reference; Report automation: The system supports the scheduled generation of daily, monthly and annual analysis reports, covering alarm history, trend analysis and processing records, and can export operation analysis reports; Specific data statistics: Regular statistics on equipment operating parameters, start and stop time, energy storage motor action times, etc., provide accurate data support; Reservoir water level statistics: The system automatically generates daily maximum and minimum reservoir water level statistics and change trends to assist management decisions.

[0024] Step 4: Intelligent trend analysis and troubleshooting decisions The system provides intelligent status monitoring and fault auxiliary decision support based on equipment operating parameters and historical data: Multi-dimensional trend analysis: Combine operating conditions and historical data to analyze equipment operating efficiency and potential hazards, identify possible causes of mutations and issue warnings; Auxiliary fault location: Based on alarm data and equipment status, it provides possible fault causes and equipment location suggestions to help operators respond quickly; Fault handling suggestions: Through the built-in fault handling knowledge base and combined with historical cases, it provides handling measures, emergency plans and safety risk assessments.

[0025] The key points of the invention are: 1. It can provide trend warning, predict abnormal defects in advance, and eliminate accidents in the bud. Based on the equipment historical data and multi-operating condition operation model, the present invention can automatically learn and calculate the alarm threshold of the equipment in different states, and dynamically adjust the threshold as the equipment operating conditions change. It can identify potential anomalies in advance and avoid false alarms or missed alarms caused by fixed threshold settings.

[0026] 2. Comprehensive alarm information and flexible judgment conditions. The intelligent alarm system no longer uses a single monitoring or simple logic to alarm, but makes a combined judgment through multiple measurement points and then issues an alarm based on certain conditions.

[0027] 3. Equipped with emergency guidance, able to provide effective guidance and assistance in emergency handling after the alarm is issued. After the alarm is issued, provide guidance and suggestions on the handling methods of the alarm according to the relevant content in the compiled typical operation experience database.

[0028] 4. It has the function of multi-device linkage. After the alarm occurs, the on-site cameras and other sensing devices are used to further patrol and explore the location where the abnormality occurs.

[0029] The present invention has the following main beneficial technical effects: 1. This technical solution realizes the real-time collection and unified management of various measuring point data of the hydropower station by deploying the intelligent monitoring function on the IMC6 system and communicating with the IMC3 system. The construction of a centralized data pool not only eliminates the information islands between systems, but also improves the efficiency and accuracy of data collection. At the same time, the validity and correctness of the collected data are checked to filter out invalid information, which fundamentally improves the data quality. The data integration between the monitoring systems provides a comprehensive and reliable foundation for subsequent analysis, greatly enhancing the liquidity and utilization of data.

[0030] 2. The technical solution establishes a dynamic threshold model for equipment operation through the automatic learning and analysis of historical data, and can adjust the alarm threshold in real time according to different working conditions. Through vertical and horizontal comparative analysis, it can not only detect abnormalities in the equipment operation status, but also predict future trends and provide early warnings. Intelligent analysis of long-term operating trends can identify potential operating hazards of equipment and provide a basis for preventive maintenance of equipment. This multi-dimensional status monitoring and analysis improves the accuracy of alarms and the timeliness of responses, significantly reducing the probability of equipment failures and operating risks.

[0031] 3. The deep integration of intelligent screen patrol and automated reporting functions replaces the traditional manual recording and analysis work, greatly reducing the burden on operators. By automatically generating various operation reports and fault analysis reports, the accuracy and timeliness of the data are ensured, while providing record files that are convenient for subsequent query and optimization. The automation of the screen patrol function makes the operation status monitoring more regular and comprehensive, which helps to find problems in a timely manner. In addition, the emergency fault status push function is linked with industrial television to help operators quickly and intuitively understand equipment failures and make correct decisions, further improving operation efficiency.

[0032] 4. The auxiliary fault location and handling function of this solution provides multiple feasible suggestions by combining historical alarm data with operating conditions, helping operators to quickly and accurately locate problems and take measures. The establishment of a knowledge base of fault handling results provides an intelligent reference for solving similar problems, significantly improving processing efficiency and safety. At the same time, through the emergency status push function, relevant information can be delivered to responsible personnel and management in a timely manner to ensure that emergencies are responded to quickly. The linkage and integration of multiple systems further enhances the coordination of equipment abnormality handling and provides a strong guarantee for the efficient and stable operation of the system.
