Abstract
The utility model aims at providing an instrument specially used for detecting leakage of ethylene gas by infrared imaging. According to a typical absorption wavelength of the infrared absorption spectrum characteristic of the ethylene gas, an ethylene gas infrared imaging leakage detector is firstly designed. The whole instrument comprises an instrument housing, an infrared focal plane detector, an infrared image capture preprocessing and enhancement processing module, an infrared lens (a spectrum narrowband discriminator is included in), a laser designator, a liquid crystal display screen with an overturning function, a viewfinder, and an AV output port which are assembled together according to a certain requirement to form the ethylene gas infrared imaging leakage detector. The infrared focal plane detector and the infrared image capture preprocessing and enhancement processing module are disposed inside the instrument housing. The infrared imaging leakage detector acquires change of the ethylene gas infrared radiation and then performs image enhancement processing by an infrared image processing module and an acquisition processing module and outputs a result to the liquid crystal display screen or the viewfinder. As a result, the ethylene gas and the leakage position which cannot be seen usually are displayed on the liquid crystal display screen or the viewfinder of the ethylene gas infrared imaging leakage detector clearly and in real time. Without a laser and other auxiliary radiation appliances, the ethylene gas infrared imaging leakage detector achieves visible detection of the leakage of ethylene gas.
Description
Technical field
The present invention relates to a kind of instrument that ethylene gas detects Leakage Gas that is specifically designed to, when more precisely occuring to leak for petrochemical industry ethylene gas commonly used, adopt infrared imagery technique in time to find its leak position and the instrument that directly shows with visible image.
Background technology
Ethylene gas is one of base stock of petrochemical complex, also is the core of petrochemical complex industry, and ethylene gas character is active, belongs to flammable explosive gas, in case leak, will work the mischief to environment and personnel; Find that in time normal, safety in production that ethylene gas leaks for petrochemical industry have epochmaking meaning.Ethylene gas is colourless, and traditional detection method can't directly be judged the leak position; The present invention is used for strengthening algorithm with the infrared Discr. in arrowband of ethylene gas molecular spectrum coupling with for the infrared image processing of ethylene gas, has realized the detection to ethylene gas; The image of the particular location of ethylene gas and leakage can clearly be presented on the display of infrared thermoviewer, namely with visible image the concrete situation that ethylene gas leaks is directly shown.
Summary of the invention
The present invention is directed to existing ethylene gas detector and can only detect ethylene gas concentration under certain condition, but can not find the particular location that ethylene gas leaks, thereby cause in some cases awkward problem; The present invention is assembled together according to designing requirement by Instrument shell, infrared focal plane detector in Instrument shell and infrared image acquisition strengthen processing module, infrared lens, the spectrum narrowband that meets the infrared absorption spectrum feature of ethylene gas is differentiated device, laser designator, turn over function LCDs, view finder, AV output port etc., and the present invention can realize the visual detection that ethylene gas leaks.
Description of drawings

By (1) infrared lens (in have spectrum narrowband differentiate device); (2) LCDs of turn over function; (3) infrared focal plane detector and infrared image acquisition strengthen processing module (inner at Instrument shell); (4) laser designator; (5) Instrument shell; (6) view finder; (7) AV output port.
Embodiment
The following technical scheme of the concrete employing of the present invention, that is: a kind of ethylene gas infrared imaging detector, it is characterized in that, described ethylene gas infrared imaging detector is by Instrument shell (5), infrared focal plane detector in Instrument shell and infrared image acquisition strengthen processing module (3), infrared lens (in have spectrum narrowband differentiate device) (1), laser designator (4), the LCDs of turn over function (2), view finder (6), AV output port (7) etc. is assembled together according to certain designing requirement, consists of a cover ethylene gas infrared imaging detector.Described infrared thermoviewer is the infrared thermal imager system of a cover, when detecting the ethylene gas leakage, the ethene bulk absorption of leaking the infrared radiation in the surrounding environment, infrared imaging system collects the variation of ethylene gas infrared radiation, then through when detecting the ethylene gas leakage, the ethene bulk absorption of leaking the infrared radiation in the surrounding environment, infrared imaging system collects the variation of ethylene gas infrared radiation, then pass through infrared image processing module acquisition processing module, original infrared image from focal plane infrared eye collection is carried out nonuniformity correction, blind element compensation and image pre-service, add the infrared imaging detection that is used for ethylene gas based on the algorithm for image enhancement that multiplies each other every the two field picture difference, and infrared image is converted to video image, can output on LCDs or the view finder, the common like this Leakage Gas that is invisible to the naked eye, find the position of Leakage Gas by the ethylene gas infrared imaging detector, can output in the video record device by the VT mouth again image is stored, can be stored as technology files, be provided with post analysis and use.
