[0075] Specifically, based on the working data of power plant equipment, the health status and use risk of power plant equipment are analyzed, and the specific process of obtaining the abnormal operation index of power plant equipment is as follows: the normal operation time of power plant equipment is compared with the total operation time of power plant equipment to obtain the operation availability of power plant equipment; the average load of power plant equipment is compared with the rated load of power plant equipment to obtain the load rate of power plant equipment; the operation availability of power plant equipment and the load rate of power plant equipment are comprehensively processed to obtain the health status index of power plant equipment;

[0078] In this implementation scheme, in addition to regular evaluation and inspection of the equipment operation status by experts, the power plant equipment operation abnormality index can be obtained through expert experience and knowledge.

Sum each row of the normalized matrix, and then take the average value to get the weight vector.

[0081] Specifically, based on the power plant working environment data, the safety characteristics of the power plant working environment are analyzed, and the specific process of obtaining the power plant working environment abnormality index is as follows:

[0082] The average temperature value of the power plant working area is calculated by absolute value with the set safe temperature value of the power plant working area, and compared with the fluctuation value of the temperature range of the power plant working area to obtain the abnormal temperature index of the power plant working area;

[0083] The average noise intensity value of the power plant working area is calculated by difference with the safety noise standard value of the power plant working area, and compared with the safety noise standard value of the power plant working area to obtain the power plant working noise abnormality index;

[0084] The power plant working temperature abnormality index and the power plant working noise abnormality index are comprehensively processed to obtain the power plant working environment abnormality index.

[0085] In this implementation scheme, in addition to obtaining the power plant working environment abnormality index by experts performing regular evaluation and inspection on the equipment operation status, the power plant working environment abnormality index can also be calculated by the following calculation formula. The specific formula of the power plant working environment abnormality index is as follows:

[0086]

[0087] In the formula, It represents the abnormal index of the working environment of the power plant, which is used to evaluate the abnormal degree of the working environment of the power plant.

The weight factor is obtained by comparing the analytic hierarchy process.

[0088] Specifically, based on the power plant employee safety training data, the power plant personnel safety training coverage and the personnel safety training effectiveness evaluation are analyzed, and the specific process of obtaining the power plant personnel safety training index is as follows: each safety training is numbered 1, 2, 3..., i,...n in sequence, and the power plant employee attendance rate, power plant employee participation rate and power plant employee test pass rate are comprehensively calculated and processed to obtain the power plant personnel safety training index.

[0089] In this implementation scheme, the attendance of employees at each safety training is recorded, and the attendance rate can be calculated by the ratio of the number of employees who attended to the total number of employees who should attend. The higher the attendance rate, the higher the participation in the training. The participation of employees in the training activities in each safety training is recorded, and the participation rate can be calculated by the ratio of the number of employees who participated in the training activities to the total number of employees. The participation rate reflects the degree of importance that employees attach to safety training. Each safety training is assessed or tested, the test scores of the employees are recorded, and the test pass rate is calculated, that is, the ratio of the number of employees who passed the test to the total number of employees who participated in the test. The test pass rate reflects the degree of mastery of safety knowledge by employees. The data such as attendance rate, participation rate and test pass rate are comprehensively calculated and processed, and the weighted average method or other algorithms can be used to obtain the power plant personnel safety training index.

[0090] Specifically, in addition to obtaining the power plant personnel safety training index by experts through regular evaluation and inspection of the equipment operation status, the power plant personnel safety training index can also be calculated through the following calculation formula. The specific formula of the power plant personnel safety training index is as follows:

[0091] Where ω represents the power plant personnel safety training index, which is used to evaluate the safety training level of power plant personnel, and FJ irepresents the attendance rate of power plant employees at the i-th safety training, KP i represents the participation rate of power plant employees in the i-th safety training, BH i represents the pass rate of the power plant employees in the i-th safety training test, i represents the number of safety training, and n is the total number of safety training numbers.

[0092] In this implementation scheme, by calculating the safety training index, the effect of each safety training can be objectively evaluated. A higher safety training index means that employees have a higher level of mastery of safety knowledge and the training effect is better. The safety training index not only includes the attendance rate and participation rate of employees, but also takes other parameters into consideration. By monitoring the changes in the safety training index, changes in employee participation can be discovered in a timely manner, and timely measures can be taken to promote employees to actively participate in safety training. By analyzing the safety training index, problems and deficiencies in the training process can be discovered. Managers can adjust and improve the content and methods of training according to changes in the safety training index to improve the training effect. By regularly calculating and publishing the safety training index, employees' safety awareness and sense of responsibility can be enhanced. A higher safety training index can motivate employees to actively participate in safety training, thereby improving the safety management level of the entire power plant.

[0093] Specifically, the specific process of comprehensively processing the power plant equipment operation abnormality index, the power plant working environment abnormality index and the power plant personnel safety training index to obtain the power plant safety control index is as follows:

[0094] The power plant equipment operation abnormality index, the power plant working environment abnormality index and the power plant personnel safety training index are assigned weights through the hierarchical analysis method to obtain the weight factors of the power plant equipment operation abnormality index, the power plant working environment abnormality index and the power plant personnel safety training index; the power plant equipment operation abnormality index, the power plant working environment abnormality index and the power plant personnel safety training index are comprehensively processed with the weight factors of the power plant equipment operation abnormality index, the power plant working environment abnormality index and the power plant personnel safety training index to obtain the power plant safety management and control index.

[0095] In this implementation plan, a comprehensive evaluation index is obtained by comprehensively considering factors such as abnormal operation of power plant equipment, abnormal working environment and personnel safety training, which is used to evaluate the safety management level and safety risks of power plants. By decomposing complex decision-making problems into a hierarchical structure, and then determining the importance and weights of factors at each level through expert judgment and data analysis, a comprehensive evaluation result is finally obtained. In the comprehensive calculation process, weighted calculation can be performed according to the weight factor of each factor to obtain the power plant safety management index.

[0096] Specifically, in addition to regular evaluation and inspection of the equipment operation status by experts to obtain the power plant safety control index, the specific formula of the power plant safety control index is as follows:

[0097]

[0098] In the formula, Gv represents the power plant safety control index, τ represents the power plant equipment operation abnormality index, represents the abnormal working environment index of the power plant, ω represents the safety training index of the power plant personnel, α1 represents the weight factor of the abnormal operation index of the power plant equipment, α2 represents the weight factor of the abnormal working environment index of the power plant, and α3 represents the weight factor of the safety training index of the power plant personnel.

[0099] In this implementation scheme, when calculating the power plant safety control index, each index and weight factor are weighted, and exponential operation is used. This processing method may be to better reflect the relationship between each index and weight factor, and their comprehensive impact on the power plant safety control index. The three indexes of abnormal operation of power plant equipment, abnormal working environment and personnel safety training are comprehensively considered, and some special processing is performed when calculating the power plant safety control index to better reflect the impact of various aspects on safety control.

[0100] Specifically, the specific process of generating power plant safety abnormality information is as follows: compare the power plant safety management and control index with the set limit value of the power plant safety management and control index. When the power plant safety management and control index exceeds the set limit value of the power plant safety management and control index, analyze the abnormal conditions of the power plant equipment operation abnormality index, the power plant working environment abnormality index and the power plant personnel safety training index to generate corresponding safety abnormality information.

[0101] In this implementation scheme, the power plant production safety mobile management and control system can monitor the power plant's safety management and control index in real time. Once the index is found to exceed the set limit value, the system can analyze the power plant equipment operation abnormality index, the power plant working environment abnormality index and the power plant personnel safety training index, and immediately generate corresponding safety abnormality information, and issue an early warning to help managers discover potential safety risks in a timely manner. For example: when the power plant safety management and control index exceeds the set power plant safety management and control index limit value, if the power plant personnel safety training index is found to be abnormal, the employee's abnormal information will be displayed, and the power plant employee's safety training attendance rate, participation rate, and test pass rate will be obtained, and they will be transferred to other positions or retrained.

[0102] See also Figure 2, a mobile control method for power plant production safety, comprising the following steps: S1. Collecting power plant operation monitoring data and preprocessing to obtain power plant production safety data; S2. Based on the power plant production safety data, analyzing the health status and use risk of power plant equipment, obtaining the power plant equipment operation abnormality index, analyzing the safety characteristics of the power plant working environment, obtaining the power plant working environment abnormality index, analyzing the power plant personnel safety training coverage and personnel safety training effect evaluation, and obtaining the power plant personnel safety training index; S3. Comprehensively processing the power plant equipment operation abnormality index, the power plant working environment abnormality index and the power plant personnel safety training index to obtain the power plant safety control index; S4. Comparing the power plant safety control index with the set limit value of the power plant safety control index, if the power plant safety control index is greater than the limit value of the power plant safety control index, generating power plant safety abnormality information, and sending the power plant safety abnormality information to the administrator, and controlling the power plant equipment and personnel safety respectively through the administrator's operation.

[0103] In this implementation plan, the health status of power plant equipment, the safety characteristics of the working environment, and the coverage and effectiveness of personnel safety training are comprehensively considered. Through comprehensive analysis and processing of these indicators, the safety control index of the power plant is obtained.
