Description

Technical Field

[0001] The present invention belongs to the technical field of power transmission high-altitude operation safety, and in particular relates to a method, system, equipment and medium for quantitatively evaluating fatigue of high-altitude operations. Background Art

[0002] Transmission high-altitude work refers to the work that workers need to perform at a height of more than 2 meters during the installation, maintenance, and inspection of power facilities. Transmission high-altitude work often involves multiple environments such as high altitude, open air, and complex terrain, and the working conditions are harsh. Working at height faces multiple risks such as falling, electric shock, and being hit by objects. Once an accident occurs, the consequences are serious. The complex environment of transmission high-altitude work not only requires workers to have professional power knowledge and skills, but also places high demands on their physical and psychological qualities.

[0003] At present, measures for transmission height operations may only focus on a single factor, such as only considering the duration of the operation, ignoring the operational complexity brought by the voltage level and the physical burden brought by the average load, resulting in inaccurate assessment of labor intensity. Existing technologies may not take into account the impact of the operation scenario on labor intensity, resulting in the labor intensity of workers in different scenarios being mistakenly considered to be the same under the same voltage level and operation duration, affecting the accuracy of the assessment of worker fatigue.

[0004] Moreover, in the prior art, when the operator is in a state of high fatigue, if there is no timely intervention, it may cause safety accidents, such as operating errors, lack of concentration, etc., and thus fail to effectively protect the health and safety of the operator. Summary of the invention

[0005] The present invention provides a method for quantitatively evaluating fatigue of working at heights, which can indirectly evaluate the fatigue state of workers and ensure the working safety of workers.

[0006] Methods include: S101: define multiple labor intensity levels, and obtain labor intensity classification information of a single operation of an operator based on voltage level information, operation duration, and average load; S102: configuring a plurality of fatigue evaluation items, and setting a plurality of labor intensity levels matching step S101 in each fatigue evaluation item; and setting a scoring item corresponding to each labor intensity level; S103: Calculating a fatigue level score based on the labor intensity classification information obtained in step S101 and in combination with the scoring items; S104: define multiple fatigue levels, and set the score threshold, level description information, and prevention and control measures corresponding to each fatigue level; S105: Match the calculated fatigue level score with the score threshold to obtain a corresponding fatigue level, and display the level description information and prevention and control measures corresponding to the fatigue level.

[0007] It should be further explained that, in the method, the fatigue assessment items include: work labor intensity level unit, fatigue accumulation unit, occupational psychology unit and musculoskeletal unit; Defining a plurality of labor intensity levels matching step S101 for the operation labor intensity level unit and the fatigue accumulation unit respectively; Set the value of each labor intensity level and the operation frequency in the operation labor intensity level unit; The first score is obtained by multiplying the assigned value and the corresponding homework frequency.

[0008] It should be further explained that the value assigned to each labor intensity level in the fatigue accumulation unit is set and used as the second score.

[0009] It is further necessary to explain that the assignment of occupational psychology unit is set and used as the third score; Set the assignment of musculoskeletal units and the number of parts corresponding to each assignment; A fourth score is obtained based on the product of the value assigned to the musculoskeletal unit and the number of parts; The first score, the second score, the third score and the fourth score are added together to obtain a fatigue level score.

[0010] It should be further explained that the values ​​corresponding to each labor intensity level in the operation labor intensity level unit include: the values ​​of the presence of fatigue negative influence factors and the values ​​of the absence of fatigue negative influence factors; The method also includes: configuring negative fatigue influencing factors; Negative factors affecting fatigue include: special working posture, working environment and working organization; Define scores for special work posture, work environment, and work organization, respectively; When any one or more of the special working posture, working environment and working organization meets the triggering conditions, the corresponding scores are extracted, and the extracted scores are accumulated to obtain the sum of the scores of the negative fatigue influencing factors; Determine whether the sum of the scores of the negative fatigue influencing factors is greater than a preset score threshold; If it is greater than, the value corresponding to each labor intensity level is the value of the negative fatigue influencing factor; If it is not greater than, the value of the negative fatigue influencing factor is taken as if there is no such factor.

[0011] It should be further explained that, in the method, the voltage level information is divided into four levels: 110 kV, 220 kV, 500 kV and UHV; The operation duration is based on setting the corresponding operation duration interval for each voltage level; The average weight is divided into four intervals: less than 8 kg, 8 kg to 12 kg, 12 kg to 18 kg, and greater than 18 kg.

[0012] It should be further explained that step S101 also includes: Four levels of voltage correspond to at least three working time intervals as the horizontal matching information at each voltage level, and are intersected with the average load as the vertical information. Each intersection is provided with corresponding labor intensity classification information.

[0013] The present application also provides a fatigue quantification assessment system for working at heights, the system comprising: a display module, a labor intensity matching module, an assessment item configuration module, a fatigue quantification module and a fatigue level assessment module; The labor intensity matching module is used to define multiple labor intensity levels and obtain the labor intensity classification information of the operator under a single operation based on the voltage level information, operation duration and average load; The evaluation item configuration module is used to configure multiple fatigue evaluation items, and multiple labor intensity levels matching those in the labor intensity matching module are set in each fatigue evaluation item; each labor intensity level is correspondingly set with a scoring item; The fatigue quantification module calculates a fatigue grade score based on the labor intensity classification information obtained by the labor intensity matching module and in combination with the scoring items; The fatigue level assessment module is used to define multiple fatigue levels and set the score threshold, level description information and prevention and control measures corresponding to each fatigue level; the calculated fatigue level score is matched with the score threshold to obtain the corresponding fatigue level, and the display module displays the level description information and prevention and control measures corresponding to the fatigue level.

[0014] According to another embodiment of the present application, an electronic device is provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of a method for quantitatively evaluating fatigue of working at height when executing the program.

[0015] According to another embodiment of the present application, a storage medium is provided, on which a computer program is stored. When the computer program is executed by a processor, the steps of the method for quantitatively evaluating fatigue of working at height are implemented.

[0016] It can be seen from the above technical solutions that the present invention has the following advantages: The method for quantitatively evaluating fatigue of working at heights provided in this application defines multiple labor intensity levels, obtains the labor intensity classification information of workers in a single operation based on voltage level information, operation duration, and average load; calculates the fatigue level score in combination with the scoring items; matches the calculated fatigue level score with the score threshold to obtain the corresponding fatigue level. It is capable of quantifying the labor intensity of a single operation of workers working at heights of power transmission. It solves the problem that in the prior art, the labor intensity of workers working at heights of power transmission is often judged by experience or rough estimation, and lacks accurate quantification means.

[0017] This application comprehensively considers three important factors: voltage level, operation time and average weight, and can more comprehensively reflect the actual labor intensity of the operators. The operation risks and operating difficulties of different voltage levels are different. The operation time directly affects the degree of fatigue, and the average weight is related to physical exertion. This solves the problem of inaccurate labor intensity assessment, which may have only focused on a single factor in the past, such as only considering the operation time, ignoring the operational complexity brought by the voltage level and the physical burden brought by the average weight.

[0018] This application can further refine the labor intensity assessment by configuring the operation scene operation interface and matching it with the voltage level information. The individual differences of operators are taken into account by configuring the operation labor intensity level unit, fatigue accumulation unit, occupational psychology unit and musculoskeletal unit.

[0019] This application defines fatigue levels and sets score thresholds, which can grade the fatigue of workers. By matching fatigue levels based on total scores and displaying prevention and control measures, targeted measures can be taken to prevent workers from becoming overly fatigued and ensure operational safety. This solves the problem that previous assessment methods may only focus on some factors, resulting in one-sided assessment results that cannot truly reflect the fatigue level of workers, and thus cannot effectively protect the health of workers and operational safety.

[0022] The method for quantitatively evaluating fatigue of workers at heights provided in this application defines a variety of variables that affect fatigue factors, and conducts correlation statistical analysis. Combined with the physiological index detection data of the workers, the key factors that affect the fatigue of workers at heights of power transmission are divided into multiple dimensions such as work characteristics, work environment, work organization, and individual characteristics. In this way, a quantitative evaluation model for fatigue of workers at heights of power transmission is established, and a quantitative fatigue evaluation of the workers is conducted to timely understand the fatigue status of the workers and improve the safety of the workers when working at heights.

[0023] The following will describe in detail the steps of the method for quantitatively assessing fatigue during working at heights. For the purpose of illustration rather than limitation, specific details such as specific system structures and technologies are provided to facilitate a thorough understanding of the embodiments of the present application.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1 The figure is a flow chart of a method for quantitatively evaluating fatigue of working at heights in a specific embodiment, the method comprising: S101: Define multiple labor intensity levels, and obtain labor intensity classification information of operators in a single operation based on voltage level information, operation duration, and average load.

[0028] In some embodiments, specific values ​​of voltage levels corresponding to aerial work may be extracted from relevant project documents of power transmission work or a power grid management system, such as different levels such as 110 kV, 220 kV, and 500 kV.

[0029] To determine the duration of a job, you can use the operator's sign-in record, the start and end time record of the on-site work. For example, you can use smart work card punch-in records, on-site person in charge time registration, etc. You can count the duration of a single job from start to finish, with units accurate to hours or minutes.

[0030] The statistical average weight of this embodiment can be based on weighing the tools, equipment and other items carried by the workers before the operation using a weighing device and recording the total weight. At the same time, combined with the number of people involved in the operation, the average weight carried by each person is calculated, and the unit is generally kilograms.

[0031] A scoring standard table can be established by combining the operation time, average load and voltage level. The established scoring standard table can be formulated according to industry specifications, experience data of similar operations in the past and relevant labor intensity assessment standards to develop a scoring correspondence table for different voltage levels, operation time ranges and average load ranges. For example, the first labor intensity score corresponding to the 110kV voltage level, the operation time of 2-4 hours and the average load of 10-15 kg is a specific value.

[0032] When using the scoring standard table, the collected voltage level information, statistical working time and average load value can be matched and searched according to the scoring standard table to obtain the first score for the labor intensity of the operator for a single operation.

[0033] Table 1 shows the labor intensity classification standard for single operation of workers working at heights of power transmission. The table determines the labor intensity classification based on three factors: voltage level, working time and average load.

[0034] Table 1

[0035] According to the structure of Table 1, the voltage level (kV) is divided into four levels: 110, 220, 500 and UHV.

[0036] Operation duration (minutes): Each voltage level is divided into different operation duration intervals.

[0037] Average weight load (kg): divided into four intervals: <8, 8 - 12, 12 - 18 and >18.

[0038] In the cell content, each cell contains a number, which indicates the labor intensity classification information.

[0039] When in use, the operator can input the corresponding voltage level, such as 110 kV, 220 kV, 500 kV or UHV. According to the actual operation time, find the corresponding operation time interval. For example, at the 110 kV voltage level, the operation time intervals are <120 minutes, 120 - 180 minutes and >180 minutes. According to the average load of the operator, find the corresponding average load interval. For example, the average load is <8 kg, 8 - 12 kg, 12 - 18 kg and >18 kg.

[0040] According to the cells corresponding to the voltage level, working time and average load, the labor intensity classification information is found. The labor intensity classification information can be used to match the multiple labor intensity levels set in the fatigue evaluation item in Table 2 to obtain the corresponding assignment.

[0041] For example, at a voltage level of 110 kV, in a cell where the working time is 120 - 180 minutes and the average load is 8 - 12 kg, the labor intensity level of the operator's single operation can be matched to 2 based on Table 1.

[0042] Application example: Assume that the parameters of a certain high-altitude power transmission operation scenario are as follows: Voltage level: 220 kV; Assignment duration: 180 minutes; Average load: 10 kg; Find the row for 220 kV in the table.

[0043] In the 220 kV row, find the interval of 150-240 minutes of working time (180 minutes is within this interval). In the interval of 150-240 minutes, find the cell corresponding to the average load of 8-12 kg. Based on Table 1, the labor intensity level of the single operation of the operator is matched to 2. In this way, the labor intensity of single operations in 12 typical transmission operation scenarios can be graded.

[0044] This embodiment determines the voltage level, finds the operation time and average load range, and comprehensively judges the labor intensity level, and can assign points to the labor intensity of a single operation of workers working at high altitudes of power transmission according to the provided chart.

[0045] S102: configuring a plurality of fatigue evaluation items, and setting a plurality of labor intensity levels matching step S101 in each fatigue evaluation item; and setting a scoring item corresponding to each labor intensity level.

[0046] In this embodiment, software development tools, JavaFX and other interface development frameworks are used to configure an operation interface for inputting operation scene information. Interactive components such as text input boxes and drop-down menus are set on the operation scene operation interface to facilitate users to input specific content of fatigue assessment items.

[0047] After the operation scenario operation interface is configured, the operation scenario input information is collected. Specifically, the operator fills in the current power transmission operation type truthfully in the corresponding input component of the operation interface, and then clicks the submit button and other operations. The background of the operation scenario operation interface can set the corresponding data transmission logic, such as using the HTTP protocol to send data to the server for processing, and send the input operation scenario information to the background data processing module.

[0048] Various common operation scenarios under different voltage levels and the corresponding labor intensity data are pre-stored in the background database. The labor intensity data can be summarized based on a large number of actual operation case analyses in the past and verified and confirmed. After the data processing module receives the input operation scenario, it finds the corresponding voltage level based on the matching logic such as similarity and correlation with the stored operation scenarios under different voltage levels, and further matches the labor intensity of a single operation under the transmission operation scenario. The matching method can be through matching, scene feature matching and other algorithms.

[0049] This embodiment uses mainstream programming languages ​​and their corresponding interface development frameworks to develop the operation interface in a human-computer interaction-friendly manner to ensure that information can be accurately input and transmitted. Relying on the standard scene scoring data stored in the background database, combined with text matching algorithms, feature matching algorithms and other technical means, the operation scene and voltage level are associated and matched, and then obtained.

[0050] In some embodiments, in combination with the above step S101, this embodiment configures multiple fatigue assessment items to specifically include work labor intensity level, fatigue accumulation, occupational psychology and musculoskeletal injuries.

[0051] The details are shown in Table 2. In each fatigue evaluation item, a plurality of labor intensity levels matching step S101 are set; and a scoring item is correspondingly set for each labor intensity level.

[0052] S103: Based on the labor intensity classification information obtained in step S101 and in combination with the scoring items, a fatigue grade score is calculated.

[0053] It should be noted that, in combination with Table 2, the fatigue assessment items include: work labor intensity level unit, fatigue accumulation unit, occupational psychology unit and musculoskeletal unit.

[0054] Define multiple labor intensity levels matching step S101 for the operation labor intensity level unit and the fatigue accumulation unit respectively; set the assignment and operation frequency of each labor intensity level in the operation labor intensity level unit; and obtain a first score based on the product of the assignment and the corresponding operation frequency.

[0055] This embodiment also sets the value of each labor intensity level in the fatigue accumulation unit as the second score. The fatigue accumulation unit is the number of consecutive days of operation. Here, the operator or supervisor manually inputs it into the operation scene operation interface, and the system matches the corresponding second score according to the number of days and the coefficient.

[0056] This embodiment also provides the assignment of the occupational psychology unit as the third score.

[0057] Setting the value of the musculoskeletal unit and the number of parts corresponding to each value; obtaining a fourth score based on the product of the value of the musculoskeletal unit and the number of parts; In summary, the fatigue level score is obtained by adding the first score, the second score, the third score and the fourth score.

[0058] Table 2

[0059] In conjunction with Table 2, the configuration operation interface specifically includes input operation interfaces such as operation characteristics, continuous operation duration, and individual characteristics. The operation characteristics section can set a drop-down menu to select specific feature options such as high-altitude operation and live operation; the continuous operation duration section sets a time input box to facilitate the input of days, hours, etc.; the individual characteristics section can set input items such as age, gender, health status, etc., and set a submit button to transmit the input information to the background for processing.

[0060] This embodiment can discuss and formulate a scoring standard table corresponding to different work characteristics, continuous work time ranges, and individual characteristics based on the actual performance, fatigue conditions, and relevant medical and labor theories of a large number of past power transmission workers.

[0061] For example, it is possible to specify how many points are assigned to high-altitude work characteristics, how many points are assigned to continuous work for more than 8 hours, how many points are assigned to individual characteristics over a preset age, etc. These standards can be stored in the background database for subsequent matching.

[0062] After the operator inputs specific operation characteristics, continuous operation duration, and individual characteristic-related content on the interface and submits it, the background data processing module receives this information, looks up the corresponding scores through logical judgment according to the pre-set score assignment standard table, and then adds these scores, or calculates the mean square error, or by other means, and finally matches the third score of the operator.

[0063] This embodiment uses interface elements such as forms, sliders, checkboxes, etc. to obtain user input. The pre-defined score assignment criteria are stored in a database or configuration file for quick matching.

[0064] S104: Define multiple fatigue levels, and set the score thresholds, level description information, and prevention and control measures corresponding to each fatigue level.

[0065] The specific definition method can be based on the human-computer interaction method for interface operations, and the defined content is shown in Table 3.

[0066] This embodiment can define multiple fatigue levels and set the score thresholds corresponding to each fatigue level. Considerations for setting the score thresholds. For example, comprehensively define multiple fatigue levels based on labor intensity, operation duration, operation environment, and individual differences.

[0067] Among them, the labor intensity can be evaluated according to the difficulty, complexity, and physical consumption degree of the operation. The operation environment can be based on the fact that harsh environments such as high temperature, high humidity, and high altitude will increase the fatigue of the operator. Considering individual differences such as the age, gender, health status, and physical condition of the operator, configure the score thresholds corresponding to each fatigue level.

[0068] Specifically, through actual research and data analysis, collect the fatigue data of operators under different labor intensities, operation durations, and environments. Analyze the collected data to find the correlations between fatigue and factors such as labor intensity and operation duration. According to the data analysis results, combined with experience and actual situations, determine the score thresholds corresponding to each fatigue level. Through actual application and feedback, verify and adjust the score thresholds to ensure their accuracy and practicality.

[0069] S105: Match the calculated fatigue level score with the score threshold to obtain the corresponding fatigue level, and display the level description information and prevention and control measures corresponding to the fatigue level.

[0070] This embodiment combines the above steps S101 to S104 and gives the corresponding methods for the fatigue levels and prevention and control measures of transmission line high-altitude operators, as shown in Table 3.

[0071] Table 3

[0072] In some specific embodiments, Table 3 shows the fatigue level classification of transmission line high-altitude workers and their corresponding prevention and control measures, which can ensure the safety and health of workers. The fatigue levels range from Level I (monitoring-level fatigue) to Level IV (risk-level fatigue), and each level corresponds to different descriptions and specific prevention and control measures.

[0073] The specific steps for classifying the labor intensity of a single operation can include: During the operation, regularly monitor the physiological and psychological states of the workers, including physiological indicators such as heart rate, body temperature, reaction time, and psychological indicators such as mental state and concentration. According to the monitoring results, score each physiological and psychological indicator and accumulate the total score. Determine the fatigue level of the workers based on the total score.

[0074] For the prevention and control measures, corresponding prevention and control measures can be taken according to the determined fatigue level. From Level I to Level IV, the prevention and control measures are gradually strengthened, from humanistic care, optimizing the work content to stopping the operation, to ensure the safety of the workers. Through Table 3, effective monitoring and management of the fatigue state of transmission line high-altitude workers can be achieved, thus ensuring operation safety and reducing safety risks caused by fatigue.

[0075] In this embodiment, in combination with the scoring items, calculate the fatigue level score; match the calculated fatigue level score with the score threshold to obtain the corresponding fatigue level, and display the grade description information and prevention and control measures corresponding to the fatigue level. The fatigue situation of high-altitude workers can be understood, and the analytic hierarchy process can be used to conduct a correlation analysis of transmission line high-altitude operation fatigue. Combining operation characteristics, operation environment, work organization, and individual characteristics, quantitatively evaluate the fatigue of high-altitude workers before they start work, and propose corresponding prevention and control measures according to the evaluation results, so as to reduce the occurrence of high-altitude falling accidents.

[0076] For this embodiment, in the background server, the Python language can be used to calculate the fatigue level score based on the labor intensity classification information obtained in step S101 and in combination with the scoring items; that is, obtain the total score corresponding to the worker's current operation.

[0077] This embodiment also sets the corresponding relationship between the score threshold and the fatigue level: Based on the relevant standards for evaluating the fatigue of transmission line workers in the industry, combined with a large number of past actual case analyses of the relevant definition of fatigue degree, and define multiple fatigue levels (such as mild fatigue, moderate fatigue, severe fatigue, etc.). At the same time, set the corresponding score threshold range for each fatigue level, and store these corresponding relationships in the system configuration file or database table for convenient subsequent query and matching.

[0078] For matching fatigue levels, the range query in the database query statement or the conditional judgment statement in the programming language can be used to determine within which threshold range the total score is located, and the calculated total score is compared and matched with the stored score threshold range to determine the corresponding fatigue level of the operator.

[0079] In the embodiment, the text content of specific prevention and control measures corresponding to different fatigue levels can also be pre-edited. For example, in case of mild fatigue, it is suggested to take proper rest and replenish water; in case of moderate fatigue, it is recommended to increase the frequency of rest and do simple relaxation activities; in case of severe fatigue, it is required to stop working and arrange professional medical examinations, etc., and the relevant content can be stored in association with the fatigue level. After matching the fatigue level of the operator, the corresponding prevention and control measures text is displayed through the web interface or mobile APP interface, etc., using the front-end development technology, so that the operators and on-site managers can view and implement the corresponding measures.

[0080] The method of this embodiment can use a programming language to implement the summation calculation of the assigned points to obtain a total score. The fatigue level is determined by judging the threshold range to which the total score belongs through programming logic, and then the related prevention and control measures text is displayed on the corresponding interface using front-end development technology to display the prevention and control measures. By comprehensively considering multiple factors such as voltage level information, operation time, average load, operation scene, operation characteristics, continuous operation time, and individual characteristics, accurate data support is provided for the fatigue assessment of workers working at high altitudes of power transmission. It avoids the one-sidedness of single-factor evaluation and improves the objectivity and reliability of the evaluation.

[0081] In combination with the above-mentioned fatigue quantitative assessment method for working at height, this embodiment further defines fatigue assessment items. Specifically, as shown in Table 4, fatigue assessment items include: work labor intensity level unit, fatigue accumulation unit, occupational psychology unit and musculoskeletal unit.

[0082] This embodiment defines multiple labor intensity levels matching step S101 for the operation labor intensity level unit and the fatigue accumulation unit respectively; sets the assignment and operation frequency of each labor intensity level in the operation labor intensity level unit; and obtains a first score based on the product of the assignment and the corresponding operation frequency.

[0083] Set the value assigned to each labor intensity level in the fatigue accumulation unit and use it as the second score.

[0084] This embodiment also provides the assignment of the occupational psychology unit as the third score.

[0085] Set the assignments of musculoskeletal units and the number of parts each assignment corresponds to.

[0086] A fourth score is obtained by multiplying the assignment based on the musculoskeletal unit by the number of parts; The first score, the second score, the third score, and the fourth score are added together to obtain the fatigue level score.

[0087] In this embodiment, the assignments corresponding to each labor intensity level of the job labor intensity level unit include: an assignment with negative fatigue influencing factors and an assignment without negative fatigue influencing factors.

[0088] Wherein, the method further includes: configuring negative fatigue influencing factors; The negative fatigue influencing factors include: special working postures, working environments, and work organizations; Scores for special working postures, working environments, and work organizations are defined respectively; When any one or more of the special working postures, working environments, and work organizations meet the trigger conditions, the corresponding scores are extracted, and the extracted scores are accumulated to obtain the sum of negative fatigue influencing factor scores; Judge whether the sum of negative fatigue influencing factor scores is greater than a preset score threshold; If it is greater, the assignment corresponding to each labor intensity level takes the assignment with negative fatigue influencing factors; If it is not greater, the assignment without negative fatigue influencing factors is taken.

[0089] Combined with Tables 3 and 4, the assignments of the job labor intensity levels in Table 3 include two assignment methods. The assignment outside the parentheses is the assignment without negative fatigue influencing factors. The assignment inside the parentheses is the assignment with negative fatigue influencing factors.

[0090] Exemplarily speaking, there are three types of negative fatigue influencing factors: special working postures, working environments, and work organizations.

[0091] Among them, the special working postures involve two scenarios. One is whether it is a special tower type (such as cat head tower, wine cup tower, etc.) operation. The other is whether additional force is required to maintain body balance or reach the working position.

[0092] If it is a special tower type (such as cat head tower, wine cup tower, etc.) operation, the score is set to 1 point. If not, it is 0 point.

[0093] Similarly, if additional force is required to maintain body balance or reach the working position, the score is set to 1 point. If not, it is 0 point.

[0094] Furthermore, two scenarios are set in the working environment. One is whether there are adverse meteorological conditions such as wind force level 3 - 4, high temperature (35°C - 37°C), low temperature (-5°C - -15°C), etc. The other is whether there are special regions such as plateau, high altitude (3000 meters), etc.

[0095] If there are adverse meteorological conditions such as 3~4 wind, high temperature (35℃~37℃), low temperature (-5℃~-15℃), the score is set to 1 point. Otherwise, it is 0 points.

[0096] Similarly, if there are special areas such as plateaus, high altitudes (3000 meters), the score is set to 1. Otherwise, it is 0.

[0097] Furthermore, two scenarios are set in the operation organization, one is whether it is a night operation, and the other is whether it is not the first operation of the day.

[0098] If there is a night job, the score is set to 1. If not, it is set to 0.

[0099] If there is a non-first job of the day, the score is set to 1. Otherwise, it is set to 0.

[0100] In this embodiment, the above scores are added up separately, that is, the scores of the three types of special working posture, working environment and working organization are added up to obtain the total score of the negative fatigue influencing factors.

[0101] The total score of the negative fatigue influencing factors is compared with the preset score threshold. If the total score of the negative fatigue influencing factors exceeds the score threshold, the value inside the brackets in Table 2 is taken. For example, under the labor intensity of level 1, the value outside the brackets is "2" and the value inside the brackets is "4".

[0102] If the total score of the negative fatigue influencing factors does not exceed the score threshold, the value outside the brackets is taken.

[0103] When the total score of the negative fatigue influencing factors does not exceed the score threshold, the score is taken from the value outside the brackets, that is, 1-level labor intensity is assigned 4 points, 2-level labor intensity is assigned 4 points, 3-level labor intensity is assigned 6 points, and 4-level labor intensity is assigned 8 points.

[0104] When the total score of the negative influencing factors of fatigue exceeds the score threshold, the score will be taken from the score in brackets, that is, 4 points for level 1 labor intensity, 6 points for level 2 labor intensity, 8 points for level 3 labor intensity, and 10 points for level 4 labor intensity.

[0105] Table 4 further gives the additional scores for each work scenario under the negative factor of fatigue.

[0106] Table 4

[0107] As an implementation method, the score threshold is set to 2.5 points. When the total score of the fatigue negative influencing factor is compared with 2.5 points, the following two situations will occur.

[0108] (1) When there are no negative factors affecting fatigue, or the cumulative score is less than 2.5, the values ​​outside the brackets in Table 3 are taken, that is, 1-level labor intensity is assigned 4 points, 2-level labor intensity is assigned 6 points, 3-level labor intensity is assigned 6 points, and 4-level labor intensity is assigned 8 points.

[0109] 2) When there is a negative influencing factor of fatigue and the cumulative score is greater than or equal to 2.5 points, the value in Table 3 is the value inside the brackets, that is, 4 points for level 1 labor intensity, 6 points for level 2 labor intensity, 8 points for level 3 labor intensity, and 10 points for level 4 labor intensity.

[0110] In this way, this method solves the problem that previous evaluation methods may only focus on some factors, resulting in one-sided evaluation results, which cannot truly reflect the fatigue level of operators, and thus cannot effectively protect the health and work safety of operators.
