Chemical accident site poisonous gas monitoring system and emergency processing method thereof

Abstract

The invention relates to a chemical accident site poisonous gas monitoring system and an emergency processing method thereof, and belongs to the technical field of dangerous chemical accident emergency rescue. The system comprises a mobile robot composed of a wheel-type driving mechanism, a support structure, a lead screw drive assembly, a poisonous gas monitoring assembly, an image collection assembly, a wireless sending module, a control command receiving module, a power module and a motion control module and a remote monitoring subsystem which is in wireless communication with the mobile robot. The method comprises the steps that the rotating speed of the mobile robot is controlled, and straight-line forward moving and turning of the mobile robot are achieved; the mobile robot is controlled to adjust the sampling height of a poisonous gas sensor; according to the poisonous gas concentration, GPS information and weather information, a gas diffusion model is selected, and leakage source intensity is obtained through calculation; according to the poisonous gas leakage accident module and the leakage source intensity, the maximum personal casualty influence range of a poisoning accident is obtained and displayed on a GIS map, and therefore the personnel evacuating range is determined.

Description

technical field [0001] The invention belongs to the technical field of chemical accident emergency rescue, so it is particularly a method for obtaining the concentration of toxic gas, GPS information and video information at the scene of a leakage accident, and comprehensively analyzing the accident scene and reflecting the intensity of the leakage source according to these information and meteorological information. A system and method for determining the scope of personnel evacuation and providing auxiliary decision-making information for emergency rescue. technical background [0002] After a chemical accident occurs, a large amount of toxic and harmful gases may leak out, endangering the safety of surrounding residents and the personal safety of rescuers. In order to ensure the safety of rescuers and scientifically delineate the evacuation range of surrounding personnel, it is necessary to use the mobile robot system to monitor the toxic gas and video on the site in real...

AI Technical Summary

Problems solved by technology

However, most of the existing mobile robots can only monitor one or two gases in real time, and cannot dynamically adjust the sampling height during the toxic gas monitoring process. The toxic gas information monitored by the mobile robot is used to calculate the leakage source strength and the accident impact range. , the emergency decision-making method for determining the evacuation range have not been reported
