A method for emergency evacuation of personnel in poison gas leakage accidents based on collaborative perception

Abstract

The invention discloses a toxic gas leakage accident personnel emergency evacuation method based on collaborative sensing. Wireless sensor nodes are mounted on emergency exit doors of a petrochemical plant. A plurality of static nodes are arranged in the petrochemical plant. Field personnel are defined as moving nodes. When toxic gas is leaked, wireless sensor nodes generate information packets {exit IDs, coordinates (x, y) and toxic gas concentration} to neighbor nodes in a communication range. The neighbor nodes receiving the information packets broadcast the received information packets and own information packets {exit IDs, coordinates (x, y) and toxic gas concentration} to the neighbor nodes in other communication range. The field personnel judge the toxic gas concentration and the distance to the emergency exit doors according to the received information packets and take evacuation measures. According to the method, the static nodes and the moving nodes are used for keeping the connectivity of a whole sensor network, the node communication cost is reduced, and moreover, a coverage degree demand is satisfied on the basis of classifying harm of the toxic gas.

Description

technical field [0001] The invention relates to an emergency evacuation method for personnel in a poison gas leakage accident based on cooperative perception, and belongs to the field of emergency personnel evacuation. Background technique [0002] In the process of production, transportation and storage of hazardous chemicals industry, there are safety hazards such as fire, explosion, leakage and penetration of toxic substances. A little carelessness will endanger the safety of personnel and cause bad social impact. At the same time, due to the characteristics of hazardous chemicals such as great harm, great damage and wide scope, it is difficult to quickly implement pre-disaster prevention, post-disaster emergency treatment and post-disaster reconstruction. The multiple hazardous chemical explosion accidents that occurred in our country and the rescue measures taken after the incident revealed that the safety production monitoring of hazardous chemicals is not in place, an...

Problems solved by technology

At the same time, due to the characteristics of hazardous chemicals such as great harm, great damage and wide range, it is difficult to quickly implement pre-disaster prevention, post-disaster emergency treatment and post-disaster reconstruction.

The multiple hazardous chemical explosion accidents that occurred in our country and the rescue measures taken after the incident revealed that the safety production monitoring of hazardous chemicals is not in place, and there are insufficient emergency measures and evacuation rescue in the event of an accident, basically relying on traditional manual monitoring and fire rescue , in terms of employee self-rescue and automatic monitoring, the performance is seriously insufficient, specifically reflected in the lack of effective integration and utilization of modern communication monitoring and rescue, resulting in huge casualties and economic losses

[0003] There are the following deficiencies in the existing technology: 1. Distributed emergency network communication, which solves the defects of node death and inability to transmit data in traditional network communication after poison gas leakage; 2. Traditional network communication has a large data transmission burden after poison gas leakage, Long time, instability and other issues
