Extensible ball type matrix grassland fire danger monitoring method and device

Abstract

The invention discloses an extensible ball type matrix grassland fire danger monitoring method and device. The method comprises the following steps: 1, selecting three kinds of representative tree species or shrubs on the periphery of a grassland with fire danger to be detected, taking wood parts of each tree species or shrub and carrying out drying, and then making three wood balls with the diameters of 0.3 cm, 0.4 cm and 0.5 cm to serve as combustible humidity balls, wherein three wood balls are manufactured in each diameter level; 2, connecting three types of combustible humidity balls withthree diameter levels into a 3*3 combustible humidity ball matrix by an insulator, wherein the distance between two adjacent groups of combustible humidity balls is greater than 3cm, and arranging the combustible humidity balls with different diameters in a staggered manner. The combustible humidity balls are made of local tree species or shrubs, and the combustible humidity balls are well suitable for local fire danger forecasting; the multipath combustible humidity ball matrix arrangement is adopted, and the combustible humidity balls are helpful for obtaining multiple types and path levelsof combustible humidity; and the device has better precision and deployability, conforms to the actual situation and is high in monitoring precision.

Description

technical field [0001] The invention relates to the related technical field of fire monitoring, in particular to an expandable spherical matrix grassland fire risk monitoring method and device. Background technique [0002] Grassland fire risk monitoring is an important part of grassland fire management. It has gradually developed from a simple fire risk assessment based on weather elements to a comprehensive fire risk forecast. Meteorological fire risk is adopted, and meteorological factors are used to forecast fire risk indirectly. Since the humidity information of combustibles cannot be obtained directly, the forecast results have certain limitations. [0003] However, the existing grassland fire risk monitoring only uses meteorological factors for meteorological fire risk forecasting. Since the humidity information of combustibles cannot be obtained directly, the forecast result is an indirect result and has certain limitations; the existing monitoring of combustibles hu...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an expandable spherical matrix grassland fire risk monitoring method and device to solve the existing grassland fire risk monitoring mentioned in the above-mentioned background technology. Meteorological factors are only used for meteorological fire risk forecasting, because it is impossible to directly obtain combustible Therefore, the forecast result is indirect and has certain limitations; the existing methods for monitoring the humidity of combustibles generally need to be manually adopted, such as weighing and drying, and the drying method for combustible humidity measurement or humidity The accuracy of rod automatic weighing is greatly affected by the external environment, which consumes a lot of labor and is difficult to deploy on a large scale; and there is currently no standardized manufacturing method for wood combustible humidity sensors, and there is no matrix combustible humidity bulb for fire risk forecasting. Scenarios and deployment scenarios, so issues that need to be improved
