Embodiment Construction

[0038] figure 1 Shown is the flow chart of the method for determining emergency repair path planning of the present invention, and the method process of the present invention is as follows:

[0039] Establish a three-dimensional model of the factory, including all primary processing devices, secondary processing devices and different equipment involved in each device. At the same time, define the geographic coordinates V corresponding to each node of the road in the factory area i =(x i ,y i ). Determine the mapping table of the corresponding relationship between each device and equipment of the factory and its nearest road node, and compare the geographic coordinates D of the device and equipment j =(DX j , DY j ) and the Euclidean distance between all defined road node coordinates Find the smallest road node V among them l =(x l ,y l ), establish a correspondence table between the two The network topology graph G=(V, E) is defined by all the road nodes in the f...

Abstract

The invention discloses a planning method for determining first-aid repair paths, which comprises the following steps of: (1) defining three-dimensional geographic information of each road junction in a factory and calculating the corresponding relationship between equipment and the road junctions in the factory first; (2) if the malfunction of the equipment at the position of the factory occurs, calculating the optimum route from a rescue starting point to accident site by using a path optimization algorithm; and (3) calculating the rotating direction of each road junction on the optimum route, and presenting the process how breakdown lorries pass through from the starting point to the destination. The planning method has the advantages that: 1) any equipment can be set to generate malfunction in the factory, and any rescue starting point and the actual traffic volumes of different roads after the malfunction occurs can be set, and the optimum rescue route is calculated by utilizing the path optimization algorithm, which is favorable for the auxiliary decision after similar conditions occur in the reality; and (2) the sense of reality is increased by seeking the rotating directions of the breakdown lorries automatically and utilizing phenomena of firing and water spray, and operators obtain the real experience through the movement of the breakdown lorries in three-dimensional environment of virtual reality so as to contribute to the rescue command of the real conditions.

Description

technical field [0001] The invention relates to a method for determining emergency repair path planning, which is used for determining the most reasonable emergency repair path according to the accident point and surrounding equipment conditions when an accident occurs. Background technique [0002] The process industry is represented by petrochemical, electric power, steel, light industry, pharmaceutical, environmental protection, metallurgy and other industries, with continuous production process, diverse product structure, complex production industry, harsh production environment, safe, stable, long-term, full-load production , High quality as the main goal and so on. In the process industry, the continuous processing of production raw materials is usually accompanied by the process of physical property changes such as chemical, physical, and phase changes. In the typical process industry - petrochemical production, most of the devices are flammable, explosive, toxic and...
