Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0034] Please refer to figure 1 As shown, it is a block schematic diagram of a flame monitoring system 100 according to an embodiment of the present application. The flame monitoring system 100 includes a controller 110 , a camera monitoring module 120 and an igniter 130 . The igniter 130 is used to ignite a corresponding flame or arc 140 . A flame or arc 140 corresponding to igniter 130 may be used for cutting, welding, or any other application requiring a flame. In the following description, usually only the flame is mentioned, but the arc can also be applied. Since the flame monitoring system 100 may need to be installed in an industrial plant, th...

Abstract

The invention discloses a camera monitoring module for flame monitoring, which is characterized by comprising an interface module connected to an igniter; a camera shooting module used for shooting the flame corresponding to the igniter; an image processing module used for carrying out algorithm processing on the image shot by the camera shooting module to obtain an image containing the flame corepart of the flame; and a control module used for realizing the following steps: determining whether the flame is combusted unstably or extinguished or not according to the image of the flame core part of the flame; and when it is determined that the flame is combusted unstably or extinguished, enabling the interface module to send an ignition signal to the igniter, so that the igniter ignites thefire to maintain the flame combustion.

Description

technical field [0001] The invention belongs to the field of monitoring and relates to the technology of controlling the igniter by monitoring the flame condition. Background technique [0002] The metal industry often uses the high-temperature flame generated by the combustion gas to cut metal sheets or weld metal parts. For example, when cutting a steel plate, a high-temperature flame is required to burn through the steel plate. Once the flame is extinguished for various reasons, the cutting place of the steel plate will cool down rapidly. The cooling rate is hundreds of degrees Celsius per second. The rapid cooling caused flaws in the vicinity of the site, resulting in a reduction in structural strength. Even if it is barely re-cut, the cut section there is discontinuous and flat, and the entire steel plate may be scrapped, resulting in huge cost losses. [0003] The same problem occurs when welding metals. When the welding flame is extinguished for various reasons, ...
