Onboard mobile forest fire monitoring system

Abstract

The invention discloses an onboard mobile forest fire monitoring system, belongs to the technical field of forest fire monitoring, and aims to solve the problems of limitation of terrain and topography, small coverage, existence of dead spaces and gaps, low accuracy and great error in the prior art. According to the onboard mobile forest fire monitoring system, a lifting mast is arranged in a monitoring vehicle, and is connected with a monitoring nacelle through a damping device; a global positioning system (GPS) receiver, a real-time data transmission unit and a spade unit are also arranged in the monitoring vehicle; a monitoring photoelectric stabilization platform is arranged in the monitoring nacelle; and an infrared scanner and a laser ranger are arranged in an inner frame unit of the photoelectric stabilization platform, and monitor a forest fire through a visual window. By the system, the forest fire can be quickly and accurately monitored within a large range, and the position of the forest fire can be determined.

Description

technical field [0001] The invention relates to a vehicle-mounted mobile forest area fire monitoring system, which belongs to the technical field of forest area fire monitoring. Background technique [0002] Forest fire is the most terrible disaster in forestry. It will bring devastating consequences to the forest. Forest fire not only burns the forest, harms the animals in the forest, but also reduces the regeneration ability of the forest, causing soil barrenness and destruction. The role of forests in water conservation has even led to an imbalance in the ecological environment. At present, the fire monitoring methods adopted in China mainly include ground patrol, watchtower monitoring, aviation patrol, and satellite remote sensing. The main task of ground patrol is to publicize the masses, control man-made fire sources, inspect and supervise people and vehicles, and fire used in field production and life. The shortcomings are that the patrol area is small, the field of...

AI Technical Summary

Problems solved by technology

The shortcomings are that the patrol area is small, the field of vision is narrow, and when determining the location of the fire, there are often large errors due to the rugged terrain and dense forests; the monitoring of the observation tower is to observe the occurrence of forest fires through the observation tower and determine the occurrence of the fire. The location, the report of the fire, the shortcomings are that the observation effect is limited by the topography, the coverage is small, there are dead spots and gaps, and it is impossible to observe the large-scale fire, embers and underground fires with heavy smoke. The method of observation based on the experience of the personnel, the accuracy rate is low, and the error is large

Aviation patrol is to use patrol aircraft to detect forest fires, but there are also shortcomings: it is difficult to take off at night, in windy weather, and when the visibility is low on cloudy days. Able to observe a certain forest area once a day

Satellite remote sensing, using polar-orbiting meteorological satellites, land resource satellites, geostationary satellites, and low-orbit satellites to detect forest fires, has shortcomings: the accuracy of NOAA-AVHRR is low, and it requires a lot of manpower, material resources, and financial resources on the ground to verify. When it reaches 3 pixels, the fire has basically become a disaster
