A method and system for acquiring and transmitting multi-dimensional fire data in a wide-area complex environment

Abstract

The invention discloses a method and system for acquiring and transmitting multi-dimensional fire data in a wide-area complex environment. The wide-area complex environment is characterized by a large area covered, complex composition of topographic features and building facilities, and irregular distribution, including but not It is limited to forest fire prevention areas, chemical industry parks, and explosion site types, and consists of the following steps. Step 1. Rapidly deploy multiple integrated measurement units by means of airdrops from an extraterritorial airport to realize the dynamic establishment of a sensor node network covering a wide-area complex environment; Step 2, using multi-batch deployment of integrated measurement units to realize multi-dimensional fire data acquisition; Step 3, using satellite communication and sensor node network to realize adaptive data upload. The invention integrates technologies such as autonomous airdrop rapid deployment, multi-dimensional fire data acquisition, self-adaptive data upload, etc., and realizes multi-dimensional fire data acquisition and transmission in a wide-area complex environment.

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
