Deployment method of a fixed monitoring and mobile emergency system

Abstract

The present invention provides a fixed monitoring and mobile emergency system deployment method, which is applied to hazardous gas leakage in rectangular industrial parks, including: creating and drawing a first gas diffusion model; changing the wind direction, establishing and drawing a second gas diffusion model; determining The first intersection point, public area, first line segment and alarm concentration point; compare the gas concentration and alarm concentration at the first intersection point, determine the first monitoring node and the second monitoring node; take the first monitoring node or the second monitoring node as the vertex Create a first square; starting from each vertex of the first square, outwardly build multiple second squares that are on a straight line with the diagonal of the first square and have the same length; and so on until the entire rectangle is covered Industrial park; the remaining three vertices of the first square and each vertices of the second square are deployed as the third monitoring node; the four vertices of the rectangular industrial park are deployed as the fourth monitoring node. The invention has low cost and wide application range.

Description

technical field [0001] The invention relates to the technical field of emergency communication, in particular to a deployment method for a fixed monitoring and mobile emergency system applied to a rectangular industrial park when hazardous gas leaks. Background technique [0002] With the wide application of wireless sensor networks and the rise of research on communication networks in critical situations, emergency communication systems have developed rapidly, especially in the hazardous chemicals industry. Due to the production, storage, transportation and use of various chemical harmful gases and liquids, these Once the substance leaks, it may release a large amount of harmful gas into the air. After mixing with the air, the concentration reaches the threshold concentration value of the human body. At the same time, the diffusion time reaches a certain level. If the gas leakage monitoring and protection work is not done well in residential areas, these gases will cause fa...

AI Technical Summary

Problems solved by technology

[0005] At present, in many hazardous chemical gas leakage monitoring systems, the deployment of sensors is only based on the number of relevant regulations, without considering the economy and efficiency. At the same time, when a hazardous gas leakage source leaks, the wind direction is not considered. Whether the originally deployed sensor can play the best alarm function when changing, that is, where the sensor is installed can achieve efficient monitoring function with the least number of sensors

Moreover, there is no effective combination of sensor communication radius and hazardous gas leakage diffusion model for sensor deployment.
