Embodiment 1

[0061] Such as figure 1 As shown, a method for safe evacuation of a gas pipeline leakage emergency, the method comprising:

[0062] Step S1: According to the gas leakage accident consequence model, obtain the impact range of various consequences and the damage partition of the gas leakage emergency, and obtain the evacuation range of the gas leakage emergency according to the impact range of various consequences and the damage partition; the specific process is:

[0063] (1) Model analysis of gas leakage accidents

[0064] 1) According to the location of the gas accident and the description of the leakage type, the basic parameters such as the pressure and pipe diameter of the leaking gas pipeline are obtained, and based on the principle of maximizing the risk of the consequences of the gas emergency, the leakage of the gas pipeline is calculated according to the pipeline leakage model.

[0065] Method 1: When the gas pipeline leaks, there are two flow states in the pipeline ...

Embodiment 2

[0195] The present invention also provides a safety evacuation system for gas pipeline leakage emergencies, and the system includes:

[0196] The scope of influence acquisition module is used to obtain the impact scope and damage partition of various consequences of the gas leakage emergency according to the consequence model of the gas leakage accident, and obtain the evacuation range of the gas leakage emergency according to the influence scope and damage partition of various consequences;

[0197] The evacuation processing module is used to obtain the evacuation starting point, evacuation exit node, warning point, evacuation road network node and shelter;

[0198] The evacuation effect acquisition module is used to obtain the evacuation time of each road section within the evacuation range, and obtain the evacuation effect based on information such as the evacuation time of each road section, the accident injury zone where the passing road is located, and the number of surro...

Abstract

The invention discloses a safe evacuation method and system for gas pipeline leakage emergencies, and the method comprises the steps: obtaining various consequence impact ranges and damage subareas of a gas leakage emergency according to a gas leakage accident consequence model, acquiring an evacuation range of the gas leakage emergency according to the influence ranges of the various consequences and the damage subareas; acquiring an evacuation starting point, an evacuation exit node, a warning point, an evacuation road network node and a shelter place; acquiring evacuation time of each road section in the evacuation range, and acquiring an evacuation effect according to the evacuation time of each road section, the accident damage subarea of the passing road, the number of surrounding dangerous chemical enterprises and other information; obtaining the optimal evacuation effect and the corresponding path and evacuation exit thereof; and obtaining an appropriate shelter place; the invhaention has the advantage that efficient and safe personnel evacuation is realized.

Description

technical field [0001] The invention relates to the field of emergency safe evacuation, and more particularly relates to a method and system for safe evacuation of a gas pipeline leakage emergency. Background technique [0002] In recent years, gas leakage emergencies have occurred frequently, and the disaster amplification effect has become more and more obvious. Gas emergencies have the characteristics of chain, complexity and amplification, which are likely to cause serious casualties. Therefore, when a gas leakage incident occurs, it is necessary to make a decision quickly and evacuate personnel in a timely and correct manner, so as to minimize the damage. Therefore, it is necessary to study a safe evacuation method for gas pipeline leakage emergencies. [0003] 1. Chinese patent application number CN201810348059.8 discloses a method and device for optimizing emergency evacuation routes of hazardous chemical enterprises. The method is to simulate leakage by constructin...
