Micro-scale initiating explosive device ignition temperature field measuring device and temperature measurement method thereof

Abstract

The invention discloses a micro-scale initiating explosive device ignition temperature field measuring device and a temperature measurement method thereof. The micro-scale initiating explosive device ignition temperature field measuring device comprises an image capture light path system, a mechanical installation device, a computer and software. The image capture light path system comprises a neutral-density filter, an imaging lens and a high-speed camera; the mechanical installation device comprises a light-shading installation box, a window fixed ring, a guide rail, a sliding block, a supporting rod, a fixture, a camera installation platform and the like; and the computer and the software comprise the computer, a data transmission line, temperature measurement processing software and the like. The neutral-density filter is used for uniform filtering in a wave band of 400 to 700 nm, and the upper limit of temperature measurement can be improved, so that the light intensity is prevented from being too high to measure the temperature. The imaging lens and the high-speed camera are used for capturing image signals, the light-shading installation box can prevent the influence of environmental false light, and all components and parts can be fixed by the guide rail, the sliding block, the supporting rod, the fixture, the camera installation platform and the like, so that measurement alignment is guaranteed; and the computer and the software can be used for processing images during standardization and measurement.

Description

【Technical field】 [0001] The invention belongs to the technical field of temperature measurement, and in particular relates to a microscale pyrotechnic product combustion temperature field measurement device and a temperature measurement method thereof. 【Background technique】 [0002] In daily life and industrial production process, it is often necessary to measure the temperature of various objects. Temperature is a very important index parameter in many technical fields. In many fields such as industry, medical treatment, military affairs and life, temperature measuring devices are required to monitor temperature. The automatic monitoring of temperature has become one of the important measures for safe production and loss reduction in all walks of life. In certain occasions, due to the scattered and remote monitoring points, the traditional temperature measurement method has a long period and high cost, and the surveyor must go to the site to measure, so the work efficien...

Problems solved by technology

However, this temperature measurement has certain limitations. First, the emissivity model of the object must be selected accurately, because it is unknown whether the emissivity of the micro-scale pyrotechnics matches the existing emissivity model; secondly, because the three primary colors only have three channel, so the highest emissivity of the object can only choose a model with two position parameters, otherwise the temperature of the object cannot be solved; in addition, this method uses the color distribution function in the measurement. In the actual response, the sensor intensity varies with The change of light intensity is not an ideal linear curve, so these increase the measurement error of the sensor
