Abstract

The invention relates to a leakage source positioning method and device based on a positioning period and computer equipment. The method comprises the following steps: constructing an objective function model associated with gas concentration information according to a preset atmospheric diffusion model; monitoring gas concentration information of the current period and acquiring an objective function model calculation value of the current period according to the gas concentration information, an atmospheric diffusion model and an objective function model in a current period; monitoring the gas concentration information in a next period, and obtaining an objective function model calculation value of the next period according to the gas concentration information of the next period, the atmospheric diffusion model and the objective function model; and according to the objective function model calculation value of the current period and the objective function model calculation value of the next period, determining the leakage source strength and the leakage source position. According to the method, the leakage source strength and the leakage source position can be obtained according to the calculated value of the objective function model, and accurate positioning of the hazardous chemical gas leakage source is achieved.

Description

technical field [0001] The present application relates to the field of positioning technology, in particular to a method, device and computer equipment for locating leakage sources based on a locating cycle. Background technique [0002] Hazardous chemicals are often diffuse and toxic. Once leaked, it will cause serious property loss and casualties. After a hazardous chemical leakage accident occurs, locating the source of the hazardous chemical leakage as soon as possible is the basis for emergency response, emergency rescue, and assessment of the potential hazards of the accident. After a hazardous chemical leakage accident occurs, the source of the hazardous chemical leakage can be located according to the gas leakage in the hazardous chemical leakage accident. [0003] The traditional method of locating the leakage source of hazardous gas is to locate the leakage source of hazardous gas according to the concentration gradient and diffusion direction of the hazardous gas...
