Research On Safe Path Planning In Complex Enterprise Working Environment

Enterprise accidents occurred frequently in recent years. According to the enterprise safety norms and behavior of safety management method, in view of the enterprise employees work scope and the safe range of hazard, the safety of the path planning of enterprise employees in the enterprise working environment safety is meaningful. Based on the determined on the basis of static or dynamic hazards, according to the theory of complex system analysis methods to analyze group safety consciousness and safety consciousness, the relationship between individuals using the Voronoi diagram and weighted Voronoi diagram are two-dimensional behavior safety norms and limit state employees in the work environment safe path;Further considering the three dimensional environment, the use of ant colony algorithm gives employees working environment under safe state of three-dimensional optimal path.Main innovation of this article is as follows:Firstly, to establish a community safety consciousness, part of the individual safety consciousness and the mathematical model of the relationship between the individual safe consciousness. Set up employee groups static safety radius and the staff individual dynamic mathematical model of safety radius.Thus security path planning laid the foundation for the enterprise.Secondly, according to 2D environment security path planning problem, first of all gives a phase when the threat of hazard intensity(safety perception radius should not less than the threat of hazard intensity), based on the characteristics of the Voronoi diagram programming staff working environment method of two-dimensional safe path.And then presents a when the threat of hazard intensity are different(safety perception radius should not less than the threat of hazard intensity), based on weighted Voronoi diagram planning enterprise employees work environment method of two-dimensional safe path. Finally discuss how to continue to optimize the cost function according to the method of safe path.Thirdly, 2D security about safety concept and method in the path of safety has been generalized to three-dimensional path planning. Also discussed how to use ant colony algorithm to avoid hazards in 3D space and eventually get a better three-dimensional safe path.At last, through the MATLAB simulation proved in this paper a two-dimensional and three-dimensional enterprise work safety path planning method is valid.
