AI Technical Summary

Benefits of technology

The present invention has the objective to enhance an open-path gas detection device and make it better at analyzing fault indications.

Problems solved by technology

Localization of a corresponding gas leak, i.e., determination of the concentration and size of the gas cloud, is not possible, because a large cloud with a low concentration may lead to the same measured value as a small cloud with a high concentration.

Embodiment Construction

[0037]Referring to the drawings, the gas detection device schematically shown in FIG. 1 comprises a first functional device 1, which is connected to a base plate 3 via a swivel joint 2. The base plate 3 is placed on a ground surface 5 at one end of a defined monitoring area 4.

[0038]A radiation source 7, a camera 8 as well as a first analysis unit 9, which is connected to the radiation source 7 and the camera 8 in a signal-conducting manner, are integrated in a housing 6 of the first functional device 1, which said housing is encapsulated in a pressure-tight manner according to EN 60079-1.

[0039]The side of the housing 6 facing the monitoring area 4 is formed by an optically transparent passage window, through which radiation 10 generated by the radiation source 7 can exit from the housing 6. Furthermore, ambient light can enter the housing 6 via the passage window, so that an image of the monitoring area 4 can be made by the camera 8. The field of view 11 of the camera 8 is configure...

Abstract

A gas detection device has at least one functional device (1, 13), which is configured to receive radiation (10) passing through a defined monitoring area (4). At least one analysis unit (9, 19) is configured to detect and analyze a change in the received radiation (10). The received radiation (10) is based on the interaction of the radiation (10) with a gas present within the monitoring area (4). At least one camera (8) has a field of view (11) that at least partially detects the monitoring area (4).

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a U.S. National Phase Application of International Application PCT / EP2015 / 000194 filed Feb. 2, 2015 and claims the benefit of priority under 35 U.S.C. §119 of German Application 10 2014 001 704.4 filed Feb. 8, 2014 the entire contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention pertains to a gas detection device.BACKGROUND OF THE INVENTION[0003]Gas detection devices are used, for example, in plants for delivering and processing combustible and / or toxic gases in order to detect unintentionally discharged gases.[0004]Gas detection devices are known that measure the concentration of such gases locally, i.e., in the immediate surrounding area, and are interlinked with one another in order to make it possible to monitor larger areas.[0005]In addition, there also are gas detection devices with an open measured path, which are called open-path gas detection devices. The meas...
