A scalable spherical matrix grassland fire risk monitoring method and device

Abstract

The invention discloses an expandable spherical matrix grassland fire risk monitoring method and device, comprising the following steps: Step 1: Select representative three types of tree species or shrubs around the grassland to be tested for fire risk, and take wood from each tree species or shrubs part, after drying, make 3 wooden balls with diameters of 0.3cm, 0.4cm, and 0.5cm, and make 3 wooden balls for each diameter class of combustibles; The balls are connected by insulators to form a 3×3 matrix of combustible humidity balls, the distance between two adjacent groups of combustible humidity balls is greater than 3cm, and the combustible humidity balls with different diameters are arranged in a staggered manner. The present invention adopts local tree species or shrubs The production of combustible humidity balls is very suitable for local fire risk forecasting. The multi-path-level combustible humidity balls are arranged in a matrix, which is helpful to obtain the humidity of multi-type and diameter-level combustibles. It has better accuracy, deployability, and conforms to reality. situation, the monitoring accuracy is high.

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...

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
