specific Embodiment approach 1

[0031] A method for assessing differences in the risk perception ability of electric workers in this implementation mode focuses on the real problem of insufficient risk perception ability of electric workers in engineering practice according to the characteristics of the electric work environment and workers, and highlights the group of workers And the influence of individual characteristics on risk perception characteristics, explore and reveal the specific characteristics and laws of risk perception. The main research content is divided into risk perception difference analysis and risk perception ability prediction model, such as figure 1 As shown, the method is realized through the following steps:

[0032] Step 1. Collect the eye movement characteristics of the subjects in different operating environments when conducting risk searches;

[0033] Step 2. On the basis of Step 1, obtain the sensitivity of the subjects in different risk types;

[0034] Step 3. Determine the ...

specific Embodiment approach 2

[0045] The difference from the first embodiment is that in the method for evaluating the difference in risk perception ability of electric workers in this embodiment, the process of collecting the eye movement characteristics of the testees in different working environments when they conduct risk searches described in step 1, Specifically:

[0046] The eye tracker was used to collect the eye movement characteristics of the subjects during the danger search process, and the risk search characteristics were reflected by the differences in the eye movement characteristics of the subjects in different scenes. The photos of the actual operation scene containing the danger feature information were used as experimental materials. It is used to simulate the working situation with dangerous targets; in order to meet the needs of the research on the differences in the visual search and risk perception ability of the operators; among them, the types of operating scenarios used for the exp...

specific Embodiment approach 3

[0051] The difference from the second embodiment is that in this embodiment, a method for assessing differences in the risk perception ability of electric workers, the process of obtaining the sensitivity of the subjects in different risk types described in step 2 is specifically:

[0052] By collecting the eye movement characteristics of the subjects to generate gaze trajectory maps and gaze heat maps; use computer algorithms and eye trackers to obtain the regions of interest in the scene respectively, and compare the differences between the positions of different regions of interest to obtain different types of dangerous scenes The characteristics and rules of the differences in search results.

Abstract

The invention discloses a method for evaluating difference of risk perception ability of an electrician operating personnel. At present, there is no method suitable for evaluating the risk perception ability of electricians. The invention discloses an electrician worker risk perception capability difference evaluation method. The method comprises the following steps: collecting eye movement characteristics of a tested person during risk search in different working environments; on the basis of the previous step, obtaining the sensitivity degrees of the testee in different danger types; determining eye movement characteristics of the tested person in risk search under different demographic characteristics; performing data processing on the acquired eye movement data; and determining a data set of a risk perception prediction model. Therefore, the eye movement data and the risk perception ability are combined, the difference of the risk perception ability is quantified by using the eye movement data, and the risk perception ability of the operator is identified. Through the technical means of risk perception difference analysis and the risk perception capability prediction model, the risk perception capability evaluation of the electrician operation personnel is realized.

Description

technical field [0001] The invention relates to a method for evaluating differences in risk perception ability of electric workers. Background technique [0002] At present, there are few related studies on personnel risk perception in China. Similar studies include: studying workers' responses to danger warnings through field experiments, and reflecting the safety risk perception of construction enterprise operators through questionnaire surveys. The level of hazard recognition in various industries is far below ideal, and failure to recognize hazards can result in employee injury. Risk perception is a complex and multidimensional cognitive process, and employees' failure to recognize potential risks and unsafe actions taken in hazardous situations are often due to failure to notice the danger. From previous studies, it is known that the behavioral data of eye movements represent the most direct manifestation of attention, and these data can provide valuable information ab...
