Embodiment 1

[0076] reference figure 1 , This embodiment provides a stepwise simulation method for the diffusion of poisons under the action of an explosion, which includes the following steps:

[0077] S100. Obtain the explosive driving load curve;

[0078] Use fluid mechanics simulation software to simulate the diffusion of poisons under the action of explosion in segments,

[0079] The segmented simulation includes the following steps:

[0080] S200. Poison explosion dispersion section simulation: import the explosive driving load curve, and simulate the poison density cloud map and / or temperature distribution map of the poison explosion dispersion section;

[0081] S300. Poison cloud diffusion section simulation: taking various parameters at the end of the simulation of the poison explosion dispersion section as initial values, the simulation obtains the poison density cloud map and / or temperature distribution map of the poison cloud diffusion section.

Embodiment 2

[0126] reference Figure 5 This embodiment is roughly the same as the method for simulating the diffusion of poisons under the effect of explosion provided in the first embodiment, but the difference is that: the modified diffusion simulation of poisons uses a rescue system to collect on-site data and modify node data, so The rescue system includes a rescue center device 1 and a mobile terminal device 2; the rescue center device 1 includes a simulation unit 11 and a first wireless transmission unit 12, the simulation unit 11 is used to modify node data; the mobile terminal device 2 Including an information collection unit 21, a warning unit 22, and a second wireless transmission unit 23. The information collection unit is used to collect poison density and temperature at different locations on the rescue site. The warning unit 22 is used to warn rescuers to stay away from high-risk areas. An escape plan is given; the second wireless transmission unit 23 is connected to the firs...

Abstract

The invention provides a sectional type simulation method for poison diffusion under the explosion effect. The sectional type simulation method comprises the steps of obtaining an explosion driving load curve; carrying out segmented simulation on poison diffusion under the action of explosion by utilizing fluid mechanics simulation software; the segmented simulation comprises the following steps:simulating a poison explosion dispersion section, importing an explosion driving load curve, and simulating to obtain a poison density cloud chart and / or a temperature distribution diagram of the poison explosion dispersion section; and simulating a poison cloud cluster diffusion section, and simulating to obtain a poison density cloud chart and / or a temperature distribution chart of the poison cloud cluster diffusion section by taking various parameters when the poison explosion diffusion section simulation is finished as initial values. Fluid mechanics simulation software is used; the wholeprocess of poison diffusion under the explosion effect is simulated to obtain concentration and / or temperature quantized values and distribution rules of poison at different positions, so that poisoncloud and mist concentrations and / or time-varying conditions at different positions are monitored, technical support is provided for rescue workers, the safety of explosion rescue workers is guaranteed, and the rescue efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of safety protection, in particular to a segmented simulation method for the diffusion of poisons under the action of an explosion. Background technique [0002] In recent years, the explosion accidents of hazardous chemicals that have occurred continuously are "flammable, explosive, and poisonous". There are many types, large numbers, and serious harm. [0003] During the accident rescue process, the situation of the poisons under the effect of the explosion was not clear, and the concentration distribution and law of the poisons were not grasped. The type and degree of the chemical hazards could only be roughly judged, and it was difficult to carry out accurate protection, which caused the rescue work to progress slowly. [0004] The diffusion process of poison under the effect of explosion can be roughly divided into two stages: the explosion dispersion section and the cloud diffusion section. The explosive dispe...
