Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0042] The present invention is a ground-based telemetry positioning method based on instantaneous point source chemical cloud clusters. The data required for the calculations are all acquired by the infrared telemetry device itself. The calculations of the above steps can be calculated by calculation programs, such as figure 1 As shown, the specific steps are as follows:

[0043] Step 1: Acquisition of relevant parameters

[0044] Determine the position parameters (latitude and longitude) of the infrared telemetry device through Beidou or GPS positioning equipment, transform the position and azimuth coordinates of the two sets of infrared telemetry devices into plane distance coordinates, and calculate the distance between the two sets of infrared telemetry devices as 1000 meters;

[0045] Record meteorological parameters such as temperature and ca...

Abstract

The invention relates to a continental rise remote measurement positioning method based on an instantaneous point source chemical cloud cluster. Two sets of infrared remote measurement devices are utilized to carry out fixed point scanning to acquire angle parameters, a forward intersection method is utilized to determine the center point position of the chemical cloud cluster, observation data at two different moments are utilized, in combination with the instantaneous point source diffusion principle, source intensity of the instantaneous point source and the generation time, the relative distance and the cloud cluster radius of the chemical cloud cluster are acquired through inverse computation. The method is advantaged in that the diffusion theory and the forward intersection principle are comprehensively utilized, a problem of cloud cluster positioning difficulty of infrared light spectrum is solved, the new instantaneous point source chemical cloud cluster fixed point remote measurement positioning method is realized, and technical support is provided for application of infrared remote measurement devices.

Description

technical field [0001] The invention relates to a method for remote determination and positioning of instantaneous point source chemical cloud clusters based on diffusion theory and forward rendezvous principle, which is related to the application of infrared remote measurement devices and belongs to the technical field of chemical reconnaissance. 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. Instantaneous point source is a point source that releases toxic and harmful substances in an instant, such as the explosion of a single chemical reaction tank; due to the difficulty in monitoring the formation time and direction of motion of the chemical cloud cluster of the instantaneous point source, and the radius of the cloud cluster is small, it is difficult to monitor and locate. The key technical problems in chemical monitoring...
