Evaluation method, device, electronic device and storage medium for attitude load data

Abstract

The invention discloses an evaluation method, device, electronic equipment, and storage medium for attitude load data, which are used to solve the problem in the prior art that there is no occupational ergonomics evaluation method for the work posture of power grid operation and maintenance personnel working on poles . The present invention includes: acquiring the working posture data of the object to be evaluated, the working posture data including dynamic working data and static working data; determining the posture duration data; combining the posture load according to the working posture data and the posture duration data The evaluation formula is used to obtain a comprehensive score of the attitude load; according to the comprehensive score, the load degree evaluation result of the object to be detected is determined. Considering the combined action of the muscle types and the mechanism of the joint action of the pole climbing operation, as well as the actual situation of using foot buckles and seat belts, it is suitable for the evaluation of the postural load of the pole climbing operation on the power grid, and helps to monitor the muscle fatigue state of the operator , to ensure its safe operation.

Description

technical field [0001] The invention relates to the field of data evaluation, in particular to an evaluation method, device, electronic equipment and storage medium for attitude load data. Background technique [0002] For different types of work, the existing work load evaluation methods have different emphases: the handicraft industry focuses on the evaluation of the posture load of the upper body, and the upper limb load evaluation method (RULA) is commonly used for evaluation, while for the evaluation of the posture load of ground manual workers, due to More emphasis is placed on the posture of the whole body, often assessed using the Rapid Whole Body Assessment (REBA). [0003] Although the pole work of power grid operation and maintenance personnel also belongs to the category of physical labor, the existing work load evaluation methods cannot fully and accurately evaluate the work posture load for them, mainly in the following aspects: (1) The current REBA method does...

Problems solved by technology

[0003] Although the pole work of power grid operation and maintenance personnel also belongs to the category of physical labor, the existing work load evaluation methods cannot fully and accurately evaluate the work posture load for them, mainly in the following aspects: (1) The current REBA method does not target The impact of the combined effect of static work and power work on the human body load is evaluated, while the power work of the power grid operation and maintenance personnel is mainly performed on the shoulders, elbows and hands, and the static work is mainly done below the waist. Compared with power work, force work has a higher oxygen debt and is more likely to cause muscle fatigue; (2) The working posture during the operation on the pole is different from that on the flat ground: the torso (especially the waist) of the power grid operation and maintenance personnel is due to the The use of seat belts and foot buckles requires the use of seat belts to exert force on the torso. At the same time, although the feet of power grid operation and maintenance personnel stand with the help of foot buckles, one foot of the power grid operation and maintenance personnel is upright and the other is bent during the operation. Standing with a different reaction force on the standing foot than when standing on the ground or standing bent

[0004] Therefore, the REBA method cannot be fully applied to the load evaluation of the grid operation and maintenance personnel's working posture on the pole. The operation and maintenance personnel cannot accurately know the load of their work on the pole, let alone adjust the working posture of the operation and maintenance personnel
