Problems solved by technology

Therefore, the safety of human-computer cooperation of wearable exoskeleton robots has been valued by many scholars, but there is still a lack of a systematic evaluation system for actually evaluating its safety.
At the same time, when selecting the existing wearable exoskeleton robots on the market, considering the uncertainty of the safety of human-machine collaboration, there is still a lack of reasonable basis for selection
[0003] The existing human-machine collaboration safety evaluation of wearable exoskeleton robots has the following shortcomings: first, lack of a specific and targeted evaluation index system; second, lack of a systematic evaluation model; third, considering human In the face of multiple wearable exoskeleton robot products, there is no reasonable basis for selection

Embodiment 1

[0068] This embodiment provides a wearable exoskeleton robot human-computer cooperation safety evaluation system, such as figure 1 As shown, it includes the building block of the evaluation index system and the building block of the evaluation model.

[0069] The evaluation index system building block is used to preliminarily formulate the human-machine collaboration safety evaluation index system for wearable exoskeleton robots according to the three perspectives of human, machine, and human-computer interaction;

[0070] The construction of the evaluation index system includes literature review, brainstorming, and expert interviews.

[0071] Literature review: According to the theory and research related to the safety of wearable exoskeleton robots and human-machine systems, a certain theoretical foundation is laid for the preliminary analysis of factors affecting the safety of human-machine collaboration.

[0072] Brainstorming method: The indicators obtained through brain...

Embodiment 2

[0146] This embodiment provides a human-machine collaboration safety evaluation model application for a wearable exoskeleton robot. The difference of Embodiment 1 is:

[0147] This embodiment is described by taking the top drilling construction as an example.

[0148] Top drilling construction widely exists in the fields of building facilities installation, rail transit construction, auto parts assembly and so on. Through on-the-spot research, it was found that the drilling task has problems such as low work efficiency, heavy human body load, and high safety hazards. This paper takes the drilling construction project as the starting point of the case, and uses the method of fuzzy comprehensive evaluation to evaluate and compare the safety of human-computer cooperation of three wearable exoskeleton robots.

Abstract

The invention discloses a man-machine cooperation safety evaluation system and method for a wearable exoskeleton robot, and the system comprises an evaluation index system construction module which is used for preliminarily drawing up a man-machine cooperation safety evaluation index system of the wearable exoskeleton robot; the first construction module is used for constructing a hierarchical model of the man-machine cooperation safety evaluation index system; the evaluation module is used for evaluating the importance degree of the indexes in the chromatography model according to a Safy 1-9 scale method; the second construction module is used for carrying out pairwise comparison according to the importance degree evaluation grades and constructing a judgment matrix; the calculation module is used for calculating the weight of the index by adopting a normalization and sum-product method; the checking module is used for checking the consistency of the judgment matrix by adopting the consistency ratio; and the third construction module is used for constructing a membership degree matrix according to the membership degree of the index in the comment level to obtain a fuzzy evaluation matrix, and generating a man-machine cooperation safety evaluation model according to the fuzzy evaluation matrix.

Description

technical field [0001] The present invention relates to the technical field of human-computer cooperation safety evaluation, in particular to a wearable exoskeleton robot human-machine cooperation safety evaluation system and method. Background technique [0002] With the demographic dividend fading, the need for enterprise automation upgrades, and national policy support, the development of wearable exoskeleton robots has been greatly promoted as an important part of automation, intelligence, and industrialization. Through literature review, it is found that most of the scholars' researches focus on the dynamic analysis, structural design, gait planning and control strategy of human-worn exoskeleton robots during movement or work. What they have in common is that they all focus on ensuring the safety of human-machine collaboration, focus on a certain point to study its safety-related factors, and emphasize the mutual coordination and stable cooperation between humans and we...
