Attitude load data evaluation method and device, electronic equipment and storage medium

Abstract

The invention discloses an attitude load data evaluation method and device, electronic equipment and a storage medium. The invention aims to solve the problem that no professional ergonomics evaluation method for the work type operation attitude of on-pole operation of power grid operation and maintenance personnel has been reported in the prior art. The method comprises the steps of acquiring working posture data of a to-be-evaluated object, wherein the working posture data comprises dynamic operation data and static operation data; determining posture duration time data; according to the working posture data, the posture duration time data and a posture load evaluation formula to obtain a comprehensive score of a posture load; and determining a load degree evaluation result of the to-be-detected object according to the comprehensive score. The combined action of the muscle operation types of a power grid pole climbing operation, the mechanism of the combined action and the actual using situation of climbers and safety belts are taken into consideration, the method is suitable for evaluating the posture load of the power grid pole climbing operation and favorable for supervision of the muscle fatigue state of operating personnel to guarantee safe operation of the operating personnel.

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
