Method and system for acquiring and transmitting multi-dimensional fire data in wide-area complex environment

Abstract

The invention discloses a method and a system for acquiring and transmitting multi-dimensional fire data in a wide-area complex environment. The wide-area complex environment is characterized in thatthe covered area is wide, terrain features and building facilities are complex in composition, distribution is irregular, and the environment includes but not limited to forest fire prevention areas,chemical parks, explosion site types. The method comprises the following steps: step 1, quickly deploying a plurality of integrated measurement units from an airport outside a domain in an air-drop manner by utilizing aircrafts to dynamically establish a sensor node network covering a wide-area complex environment, wherein the integrated measurement units are distributed irregularly and include but are not limited to forest fire prevention areas, chemical parks and explosion site types; step 2, realizing multi-dimensional fire data acquisition by utilizing a multi-batch deployment integrated measurement unit; and step 3, realizing self-adaptive data uploading by utilizing satellite communication and a sensor node network. According to the invention, technologies of autonomous airdrop rapiddeployment, multi-dimensional fire data acquisition, adaptive data uploading and the like are integrated, and multi-dimensional fire data acquisition and transmission of a wide-area complex environment are realized.

Description

technical field [0001] The invention relates to the technical field of fire data measurement, in particular to a method and system for acquiring and transmitting multi-dimensional fire data in a wide-area complex environment. Background technique [0002] The wide-area complex environment has the characteristics of a large area covered, complex terrain and building facilities, and irregular distribution. Acquiring and transmitting its fire data requires the deployment of a large number of fire data measurement devices. If it is deployed manually, it will require a lot of manpower. It takes time to carry the fire data measurement device into the target area for on-site installation and deployment, which will lead to very time-consuming and labor-intensive deployment, extremely difficult management and maintenance, and personal safety accidents are prone to occur. At the same time, it is difficult to respond to fire data acquisition in a timely manner when a fire occurs Requir...

[0002] The wide-area complex environment has the characteristics of a large area covered, complex terrain and building facilities, and irregular distribution. Acquiring and transmitting its fire data requires the deployment of a large number of fire data measurement devices. If it is deployed manually, it will require a lot of manpower. It takes time to carry the fire data measurement device into the target area for on-site installation and deployment, which will lead to very time-consuming and labor-intensive deployment, extremely difficult management and maintenance, and personal safety accidents are prone to occur. At the same time, it is difficult to respond to fire data acquisition in a timely manner when a fire occurs Requirements: If the remote sensing monitoring of the target area is carried out through space-based or space-based platforms such as aircraft and satellites, the platform needs to be able to pass over the target area frequently. Due to the limitation of the working mechanism of these platforms, this will lead to high cost of fire data collection and time-sensitive Due to the long detection distance, some fire data cannot be measured, and some fire data can be measured but the accuracy is relatively low
