Measurement device and measurement method for water content of combustible material

Abstract

The invention provides a measurement device and measurement method for the water content of a combustible material. The measurement device comprises a containing part, an infrared sensor, a weight sensor and a controller; the containing part is provided with a containing cavity for containing the combustible material, and the top of the containing cavity is provided with an opening; the infrared sensor is arranged over the containing part, and infrared light emitted by the infrared sensor vertically irradiates the combustible material through the opening; the weight sensor is arranged at the bottom of the containing part and used for weighing the combustible material; the controller is connected with the infrared sensor and the weight sensor separately and used for controlling the infrared sensor and the weight sensor to operate and processing an infrared signal output by the infrared sensor and a weighing signal output by the weight sensor to acquire the water content of the combustible material. The measurement device can quickly and accurate measure the water content of the combustible material in a non-contact mode, be applied to water content measurement of various plant litter in a forest area and provide a reliable basis for forest fire risk rank classification.

Description

technical field [0001] The invention belongs to the technical field of forest fire prevention, in particular to the technical field of measuring the dryness index of forest combustibles, in particular to a measuring device and method for moisture content of combustibles. Background technique [0002] The possibility of fires in forest areas and the spread of forest fires are closely related to the dryness of surface combustibles in forest areas. Surface combustibles are mainly formed by the accumulation of dead branches and leaves for a long time, and the dryness is most directly reflected by moisture content. . The moisture content of fallen leaves generally refers to the percentage value of the water mass in fallen leaves and the dry mass of fallen leaves. At present, the moisture content of fallen leaves on the surface of the forest area is usually obtained by drying and weighing method: through manual sampling by forestry staff, weighing fresh weight, drying and then we...
