[0126] Before the sensors, data collectors, controllers, intelligent meters, and monitoring systems collect data, equipment detection is first carried out, and after all are detected to be qualified, the unit operation data is collected;

[0127] The collected unit operation data is imported into the database, and the unit operation data in the database is retrieved to obtain the unit data to be processed after retrieval.

[0128] Specifically, by first detecting the acquisition device and then collecting data, the problem of inaccurate data caused by equipment failures or errors can be minimized, improving the accuracy and reliability of the data.

[0150] According to the formulated storage strategy, store the data of the target unit after the data type is identified in the corresponding location according to the specified format;

[0151] After the storage is completed, the backup unit data is obtained.

[0152] Specifically, the formulation of the backup strategy, including full backup, incremental backup or differential backup, ensures that the data can be completely and effectively restored in various scenarios. The application of data encryption technology improves the security of data during backup and storage, preventing unauthorized access or tampering with the data. By selecting various backup locations such as local servers, external hard drives, network storage devices or cloud storage services, the data risk is dispersed, enhancing the reliability and fault tolerance of the data. The adoption of incremental backup and differential backup enables only the most recent full backup and subsequent incremental or differential backups to be restored during data recovery, greatly shortening the recovery time. The detailed recording of the backup log, including backup time, data volume, backup location and backup result, provides clear guidance for data recovery, improving the recovery efficiency. The application of data compression technology reduces the storage space occupied by the backup data, improving the storage efficiency. The implementation of data type recognition enables different types of data to be optimized for storage according to their characteristics, further improving the storage efficiency. The formulation of the storage strategy, including the selection of storage location and storage format, enables the data to be stored in the most effective way in the appropriate location, avoiding waste of resources. The automatic generation and recording of the backup log facilitates the tracking and management of the data, enabling the administrator to easily understand the backup and storage status of the data. Reliable data backup and storage guarantee the integrity and accuracy of the unit operation data.

[0153] To solve the problem in the prior art that the unit operation data is not analyzed more accurately and the analysis data is not optimized, resulting in the inability to effectively adjust the unit equipment according to the actual situation, please refer to Figure 1 and Figure 2 , this embodiment provides the following technical solutions:

[0154] The unit data heat rate analysis unit is also used for:

[0155] Retrieve the standard operation management data from the database and compare each item of the retrieved standard operation management data with the backup unit data item by item;

[0156] After the item-by-item comparison is completed, the heat rate data between the standard operation management data and the backup unit data is obtained;

[0157] Among them, the heat rate data includes absolute heat rate data and relative heat rate data;

[0158] The absolute heat rate data is the difference between the data of the same type in the standard operation management data and the backup unit data. The calculation formula is as follows:

[0159] P = T - Z

[0160] P represents the absolute consumption difference value; T represents the value of a certain data in the backup unit data; Z represents the value of a certain data in the standard operation management data;

[0161] The relative consumption difference data is the ratio of the consumption difference value between the standard operation management data and the backup unit data. The calculation formula is as follows:

[0162] D = P / Z * 100%

[0163] D represents the relative consumption difference value;

[0164] Use the weighted average algorithm to calculate the overall consumption difference for the absolute consumption difference data and the relative consumption difference data;

[0165] After the overall consumption difference calculation is completed, the actual unit consumption difference data is obtained.

[0166] Specifically, by comparing the standard operation management data and the backup unit data item by item, the differences between the two can be accurately found, thus ensuring the accuracy of the consumption difference data. Using the calculation formulas for the absolute consumption difference data and the relative consumption difference data, the gap between the backup unit data and the standard operation management data can be scientifically quantified, providing a reliable basis for subsequent optimization management and performance appraisal. Not only considering the absolute consumption difference data, but also introducing the relative consumption difference data makes the consumption difference analysis more comprehensive and can more accurately reflect the actual situation of the unit operation. By using the weighted average algorithm to calculate the overall consumption difference for the absolute consumption difference data and the relative consumption difference data, the actual unit consumption difference data can be obtained, providing strong support for the overall optimization of the unit. Through the consumption difference analysis, the problems and deficiencies existing in the unit operation can be found, thus guiding the operators to carry out targeted optimization adjustments to improve the unit operation efficiency and economy. By real-time monitoring and analyzing the unit consumption difference, the operation modes with high energy consumption can be found and corrected in time, thus reducing the unit energy consumption level. The consumption difference data can be used as an important basis for the performance appraisal of the operators. By comparing the consumption difference data of different operators, their operation levels and responsibilities can be objectively evaluated. Combining the consumption difference data with the performance appraisal can motivate the operators to actively improve their operation skills and energy-saving awareness, thus further improving the unit operation efficiency and economy. According to the real-time consumption difference data, the operators can dynamically adjust the unit operation parameters to ensure that the unit always maintains a better operation state.

[0167] The consumption difference data analysis and optimization unit is also used for:

[0168] Conduct anomaly analysis on the actual unit consumption difference data according to the anomaly analysis rules;

[0169] The anomaly analysis rules are retrieved from the database. When conducting anomaly analysis, if the threshold value of the actual unit consumption difference data exceeds the normal operation threshold value in the anomaly analysis rules, the actual unit consumption difference data is abnormal data;

[0170] The abnormal degree of the actual unit heat rate data that is abnormal data will be judged;

[0171] The abnormal degree judgment is to divide the abnormal degree according to the abnormal value of the abnormal data of the actual unit heat rate data;

[0172] The abnormal degree is divided into slight abnormality, moderate abnormality and severe abnormality;

[0173] The abnormal data in each abnormal degree will be analyzed for the abnormal cause. The abnormal causes include equipment failure, improper operation, environmental factor change and improper process parameter setting;

[0174] Different optimization adjustment plans will be formulated according to the abnormal cause and the abnormal degree;

[0175] After the optimization adjustment plan is formulated, the unit operation data to be executed is obtained.

[0176] Specifically, by retrieving the abnormal analysis rules from the database, the automatic abnormal analysis of the actual unit heat rate data is realized, which greatly reduces the manual intervention and improves the analysis efficiency. The abnormal degree judgment and the abnormal cause analysis also adopt intelligent methods, which can accurately divide and diagnose based on the data characteristics, further improving the intelligent level of the system. By setting the normal operation threshold, the system can accurately identify the abnormal data exceeding the threshold, ensuring the accurate monitoring of the unit operation status. The introduction of the abnormal degree division enables the system to more carefully evaluate the severity of the abnormality, providing strong support for the subsequent optimization adjustment. Considering various abnormal causes such as equipment failure, improper operation, environmental factor change and improper process parameter setting, the comprehensiveness of the analysis is ensured. This comprehensive analysis helps to quickly locate the root cause of the problem, providing an important basis for formulating effective optimization adjustment plans. According to the abnormal cause and the abnormal degree, the system can automatically generate targeted optimization adjustment plans, improving the effectiveness and pertinence of the adjustment. This personalized optimization adjustment plan helps to improve the operation efficiency and performance of the unit, reduce energy consumption and costs. Through automatic and intelligent means, the process of unit operation optimization management is simplified and the management efficiency is improved. At the same time, the system can also provide detailed abnormal data and optimization adjustment records, providing an objective basis for performance appraisal, helping to improve the management level and employee performance. Through continuous abnormal analysis and optimization adjustment, the system can continuously accumulate experience and data, providing useful references for the subsequent unit operation optimization.

[0177] To solve the problem in the prior art that there is no more accurate adjustment plan formulated according to the actual situation of the unit operation compared with the normal situation, and there is no corresponding performance appraisal according to the adjustment plan, resulting in poor effect of the unit operation status adjustment plan, please refer to Figure 1 andFigure 2 , this embodiment provides the following technical solutions:

[0178] The optimization plan generation unit is further configured to:

[0179] Generate a plan for the operation data of the unit to be executed by using a plan conversion tool;

[0180] Approve the generated plan, and after the plan approval is completed, distribute it to the corresponding working unit personnel;

[0181] Among them, before the plan is distributed, the unit equipment to be adjusted in the plan is confirmed;

[0182] Confirm the corresponding working unit personnel according to the unit equipment;

[0183] After the corresponding working unit personnel are completed, the operation data of the unit to be executed with the plan approval completed is sent through a communication channel;

[0184] The communication channel includes a unit display terminal and a working unit personnel meeting terminal.

[0185] Specifically, by using a plan conversion tool, the operation data of the unit to be executed is converted into a specific implementation plan. This process is based on heat rate analysis, which can ensure the scientificity and effectiveness of the plan. Before the plan is distributed, confirming the unit equipment to be adjusted can ensure the accuracy of subsequent adjustment work, avoid unnecessary resource waste. Through the system's analysis and processing of the unit operation data, the unit equipment can be configured and adjusted more scientifically, improving the overall operation efficiency. It can record and save the historical data of the unit operation, providing an objective and accurate basis for performance appraisal. Through the performance appraisal management system, employees can clearly understand their work performance and growth space, thus actively seeking improvement and releasing personal potential. Through the approval process, each department can understand the needs of other departments and coordinate resources to achieve common goals. This helps to improve the team collaboration ability and ensure the smooth implementation of the plan. Sending the plan through a communication channel (such as a unit display terminal and a working unit personnel meeting terminal) can ensure the security of information during transmission. Through the approval process, the approval process and results of the plan can be recorded to ensure that every operation is traceable. This helps to trace the cause in a timely manner when problems occur and take corresponding measures for improvement. Through continuous analysis and processing of the unit operation data, new problems and potential improvement points can be continuously discovered. This provides the possibility for the continuous optimization and upgrade of the unit.

[0186] The optimization plan implementation monitoring unit is further configured to:

[0187] The working crew checks the implementation plan on the communication channel, and prepares the implementation tools and personnel and conducts safety inspections according to the requirements of the implementation plan;

[0188] The implementers adjust the parameters of the unit equipment according to the implementation plan;

[0189] During and after the parameter adjustment process, the operating status of the unit equipment is monitored in real time;

[0190] If the operating status is normal, the monitoring parameters are collected and recorded by using the data acquisition equipment of the unit equipment;

[0191] The recorded monitoring parameters are marked as adjusted monitoring parameter data.

[0192] Specifically, the implementers adjust the parameters of the unit equipment according to the implementation plan, can respond in real time to the changes in the operating status of the unit, and ensure that the unit always operates in the best state. Through the differential analysis, the influence of each parameter on the coal consumption (or heat consumption) of the unit can be accurately calculated, so as to guide the implementers to carry out targeted parameter adjustment, reduce the power supply coal consumption of the unit, improve the operating efficiency. During and after the parameter adjustment process, the operating status of the unit equipment is monitored in real time, potential problems can be discovered and processed in time, and the shutdown or efficiency decline caused by unit failures can be avoided. The monitoring parameters are collected and recorded by using the data acquisition equipment of the unit equipment, providing accurate data support for the subsequent differential analysis and unit performance optimization. By recording and analyzing the adjusted monitoring parameter data, the work performance of the operating personnel in the process of unit operation optimization can be objectively evaluated. The differential analysis method can accurately reflect the influence of each parameter on the economy of the unit, thus avoiding the interference of subjective factors in the traditional performance appraisal, improving the accuracy and fairness of the appraisal. Based on the performance appraisal results of the differential analysis, a corresponding incentive mechanism can be established to reward the outstanding operating personnel, stimulating their work enthusiasm and creativity. This incentive mechanism can guide the operating personnel to pay more attention to the economy and safety of the unit operation, promote the continuous improvement of the unit operation optimization management work. The unit operation optimization management system based on the differential analysis can carry out refined management of various parameters in the unit operation process, ensuring that the unit always operates in the best state. Through the analysis and mining of historical data, potential problems and improvement directions in the unit operation can be discovered, providing strong support for the subsequent unit optimization transformation.

[0193] The implementation plan performance appraisal unit is also used for:

[0194] Compare the difference between the adjusted monitoring parameter data and the standard operation management data;

[0195] Among them, when comparing the differences, the types of the data compared are the same;

[0196] Confirm the performance change data based on the difference comparison result. The performance change data is confirmed as follows: when the difference exceeds the preset positive threshold, adjust the monitoring parameter data to performance improvement; when the difference is lower than the preset negative threshold, adjust the monitoring parameter data to performance decline; if the difference is between the positive threshold and the negative threshold, adjust the monitoring parameter data to no change.

[0197] Conduct performance index analysis based on the performance change data. The performance index analysis is to calculate the performance score by analyzing the change trend of the performance change data.

[0198] The performance score calculation gives a positive score when there is performance improvement and a negative score when there is performance decline.

[0199] Integrate the total score of the performance score with the work performance of the work crew or department. Among them, the work performance of the work crew or department is retrieved from the attendance terminal.

[0200] After performance integration, the comprehensive performance analysis data for the optimized management of unit operation is obtained.

[0201] Convert the comprehensive performance analysis data into visual data and display it on the display terminal of the department after the conversion of visual data is completed.

[0202] Specifically, by comparing the difference between the adjusted monitoring parameter data and the standard operation management data, the subtle changes in the unit operation status can be accurately captured. Real-time data comparison and analysis can ensure the timely discovery of problems, provide strong support for rapid response and optimized management. Judging performance improvement, decline or no change according to the preset positive and negative thresholds avoids the interference of subjective judgment, improves the accuracy and objectivity of the evaluation. Incorporating the change trend of the performance change data into the performance index analysis not only considers the current performance status but also the long-term change trend, which helps to comprehensively evaluate the overall performance of unit operation. Giving a positive score when there is performance improvement and a negative score when there is performance decline, this scoring mechanism can motivate the work crew or department to actively improve the unit operation performance, thereby improving the overall work efficiency. Combining the performance score with the work performance of the work crew or department not only considers the performance indicators of unit operation but also the work attitude and attendance of the personnel, realizing the comprehensiveness of performance evaluation. Converting the comprehensive performance analysis data into visualization can intuitively display the optimized management situation and performance score of unit operation on the display terminal, facilitating the management to quickly understand the overall performance status, providing detailed data support and intuitive graphical display for the management, which helps the management to make more scientific and reasonable decisions and improve the effect of unit operation optimized management. Through continuous data monitoring and analysis, problems in unit operation can be discovered and solved in a timely manner.
