Problems solved by technology

[0006] Since the location of continuous point source chemical cloud is difficult to know in advance, and the duration is short, it is greatly affected by meteorological and other factors. It is difficult to quickly locate continuous point source chemical cloud by existing chemical reconnaissance and analysis. At present, optical instruments are mainly used. Rough direction judgment with visual inspection

Embodiment Construction

[0047] Below in conjunction with accompanying drawing and embodiment the basket of the present invention is described in detail.

[0048] The present invention is a land-based telemetry positioning method for continuous point source chemical cloud clusters. The data required for the calculation all rely on infrared telemetry devices to obtain. The calculations of the above steps can be automatically calculated by a computer. The specific steps of the method are as follows:

[0049] Step 1: Acquisition of geographic coordinates

[0050] Through the cluster Beidou or GPS positioning module, determine the position coordinates of the infrared telemetry device, A 0 (x A0 ,y A0 )=(-600,600), B 0 (x B0 ,y B0 )=(-700,800).

[0051] Step 2: Acquisition of Meteorological Data

[0052] Record meteorological parameters such as temperature. Calculation of the turbulent horizontal diffusion coefficient K for the local geographic location from meteorological data 0 , Turbulent vertica...

Abstract

The invention relates to a land-based telemetric localization method of a continuous point source based chemical cloud cluster. End point position coordinates of the continuous point source based chemical cloud cluster are calculated based on angle parameters obtained by fixed-point scanning of two infrared telemetering devices according to a triangular relation formed by maneuvering, then, damage depth of the continuous point source based chemical cloud cluster is calculated, and the application amount and damage boundary of the continuous point source are calculated inversely through combination with the continuous point source diffusion principle. According to the method, the location problem of the cloud cluster by infrared spectra is solved with comprehensive application of principles of a diffusion theory, the novel maneuvering telemetric localization method of the continuous point source based chemical cloud cluster is provided, and technical support is provided for the application of the infrared telemetering devices.

Description

technical field [0001] The invention relates to a method for remote determination of continuous point source chemical cloud clusters based on diffusion theory, which is related to the specific application of infrared remote measurement devices and belongs to the technical field of chemical monitoring. Background technique [0002] Toxic and harmful substances usually form chemical clouds in the form of dispersion or evaporation, and spread downwind with the atmosphere to achieve poisonous effects. Due to the difficulty in monitoring the formation time and movement direction of chemical clouds, it is impossible to locate chemical clouds, which is the core technical problem that needs to be solved in chemical reconnaissance. [0003] A continuous point source is a point source that releases toxic and harmful substances continuously. With the rapid development of my country's chemical industry, chemical plant accidents can also be regarded as continuous point sources. The che...
