Deployment method of fixed monitoring and mobile emergency system

Abstract

The present invention provides a deployment method of a fixed monitoring and mobile emergency system and is applied to the dangerous chemical gas leakage of a rectangular industrial park. The method includes the following steps that: a first gas diffusion model is created and drawn; the direction of wind is changed, a second gas diffusion model is established and drawn; a first intersection point, a public area, a first line segment and an alarm concentration point are determined; the gas concentration of the first intersection point is compared with alarm concentration, a first monitoring node and a second monitoring node are determined; with the first monitoring node or the second monitoring node adopted as a vertex, a first square is built; with each vertex of the first square adopted as a starting point, a plurality of second squares of which the diagonal lines are on the same straight line with the diagonals of the first square and equal to the diagonals of the first square in length are built externally; other squares are built as the same manner above until the whole industrial park is covered; the other three vertexes of the first square and the vertexes of each second square are deployed as third monitoring nodes; and the four vertexes of the rectangular industrial park are deployed as fourth monitoring nodes. The deployment method of the invention has the advantages of 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...

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.
