Problems solved by technology

However, applicants have noted that it is difficult to detect gas leaks in these systems when background radiation photons and photons passing through the gas cloud are very similar
Also, these so-called traditional active / passive systems have very slow processing speeds and strictly require the camera to remain stationary, as camera movement can affect detection accuracy

Embodiment Construction

[0106] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the present disclosure. It will be apparent, however, to one skilled in the art that the present disclosure may be practiced without these specific details.

[0107] Refer to the attached Figure 1 to Figure 4 , a system for facilitating the detection of a predetermined gas is generally indicated by reference numeral 10 . Specifically, the system 10 is used to image the observed scene through a camera, and also image a predetermined gas with a predetermined absorption wavelength in the scene. In this way, see figure 2 , the user of the system 10 can detect whether there is a gas leak G in the observed scene. Specifically, hazardous gas leaks G can be detected in equipment such as in piping P associated with high-pressure installations, before the gas leaks cause serious environmental and / or personal injury,...

Abstract

This invention relates to a method of and system for facilitating detection of a particular predetermined gas in a scene (14) under observation. The gas in the scene is typically associated with a gasleak in equipment. To this end, the system comprises an infrared camera arrangement (12); a strobing illuminator device (22) having a strobing frequency matched to a frame rate of the camera; and a processing arrangement (24). The processing arrangement is configured to store a prior frame obtained via the infrared camera arrangement; and compare a current frame with the stored prior frame and generate an output signal in response to said comparison. The system also comprises a display device (26) configured to display an output image based at least on the output signal generated by the processing arrangement so as to facilitate detection of the particular predetermined gas, in use.

Description

technical field [0001] The invention relates to a gas detection system and a gas detection method, in particular to a gas leakage detection system and a method for detecting gas leakage of equipment. Background technique [0002] In various industries, undesired gas leakage from equipment such as equipment in electrical distribution systems is undesirable for various reasons such as safety, environment, operational requirements, and the like. For environmental reasons, environmental regulations around the world have adopted a stricter attitude towards the leakage and pollution of harmful gases and greenhouse gases. Therefore, it would be desirable to be able to detect and pinpoint the location of gas leaks so that appropriate remedial solutions can be deployed to address the leaks. For example, taking SF used in electrical installations 6 For example, gas leaks not only cause environmental damage, but can also lead to device failure. The problem of detecting leaks is enco...
