A method for evaluating the working ability of the physically disabled based on key kinetic factors

Abstract

The invention discloses a method for evaluating the operating ability of the handicapped based on key factors, including: (1) constructing three operating element categories of operating entity, operating body and operating space, and comprehensively describing the operating system; (2) correspondingly Generate a kinesin sequence that can complete the task; (3) assign a three-level evaluation index to each kinesin that composes the kinesin sequence; (4) identify the key kinesins, and use this as the basis for evaluation; (5) combine The key kinetic elements are used to carry out motion simulation, and the biomechanical parameters of the disabled people are measured when they execute the key kinetic elements; (6) The biomechanical parameters of normal people are used as job requirements, and compared with the biomechanical parameter measurement results of the physically disabled . Through the present invention, massive data can be avoided in the follow-up simulation and calculation process, and at the same time, the whole process of evaluating the working ability of the handicapped with high reliability and high efficiency can be realized.

Description

technical field [0001] The present invention relates to the related technical field of operation assistance for the handicapped, and more specifically, to a method for evaluating the work ability of the handicapped based on key kinetic factors. Background technique [0002] Reasonable occupational rehabilitation, job-assisted design, and employment placement and adjustment are of great value to improve the quality of life of the physically disabled. Comprehensive and accurate evaluation of job ability is an important basis for job design and placement. The evaluation method of operational ability has a direct impact on the final evaluation results. Inaccurate evaluation results will cause unreasonable job matching, lead to reduced job performance, and even cause occupational injuries to operators. [0003] At present, the existing evaluation methods for the working ability of the physically disabled can be roughly divided into five categories: functional measurement, occupat...

AI Technical Summary

Problems solved by technology

[0004] However, further studies have shown that each of the above existing evaluation schemes has its own limitations

For example, the function measurement method is similar to the ability evaluation method based on the operation scene. It evaluates specific functions, has a single index, and has little applicability. It is difficult to fully describe the multi-task work ability. Consistency in time and space cannot guarantee the construct validity and time validity of simulation assignment variables

As far as the general occupational ability evaluation plan is concerned, it only evaluates the general ability of the handicapped to work, does not target the specific work content, and cannot consider the impact of the work factor variables on the work ability of the handicapped

For occupational matching and job matching evaluation methods, they start from the perspective of the matching of damaged function and job content, and comprehensively consider the information of both functions and jobs, but they are relatively independent and poorly correlated, and completely rely on the subjective evaluation of experts Linking the information of both parties, the evaluation process is complicated, the amount of data is large and the subjectivity is strong

[0005] Correspondingly, in order to be able to predict the working ability of the physically disabled with high reliability, more comprehensive and accurate research and processing design of the work tasks are required. However, the existing task analysis methods have the following significant deficiencies or improvement needs: (1) It is impossible to make a comprehensive and dynamic description of the dimension of operation elements. Due to the limitations of the description of operation elements, it is impossible to fully predict the operation behavior of operators, thereby reducing the accuracy of evaluation of operation ability; (2) The relationship between operators and operations The task description method of system separation leads to the inability to express the strong coupling relationship between the operation elements and the individual operator's functional differences, and fails to quantify the strong interaction between the operator's ability attribute and other operation elements; (3) Neglecting the operation The influence of individual differences of operators on job elements does not take into account the description of the functional characteristics of operators. The job behavior of operators is closely related to their own ability attributes, but individual differences of operators are rarely reflected in the task model.
