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

Embodiment Construction

[0027] A high-temperature and high-speed measurement device for micro-scale pyrotechnics, including:

[0028] High-speed camera 6, this high-speed camera 6 is coaxially arranged with imaging lens 5, and described imaging lens 5 is arranged on one side of high-speed camera 6, and computer 9 is set at the other side of high-speed camera; Imaging lens is used for microscale fire The light emitted by the burning product is imaged on the negative film of the camera sensor, and the computer is used to process the collected images. The computer is connected with a trigger for triggering the burning of the pyrotechnic product.

[0029] The high-speed camera is a camera of the phantom brand, which has multiple frame numbers and resolutions to choose from. According to the actual situation of pyrotechnics burning and the requirements of measurement, the frame number of the selected camera is 58000 frames, and the resolution is 64× With 64 pixels and a pixel size of 22 μm, the target sur...

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...
