Problems solved by technology

[0003] The existing visual recognition method for the flame detection of the baker uses temperature difference detection or plasma detection as the basis for judging the flame state. Both detection methods must be in close contact with the flame, the detection components are prone to failure, and the maintenance workload is large.

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] The flame of the baker is in an open space, and there are many surrounding visual interference factors, such as sunlight, the shadow of driving and walking, and high-temperature ladles, etc., but the flame of the baker has a feature that is obviously different from environmental interference, that is, high-frequency contour jitter. This is because the gas pressure is high, the flame is sprayed, and the outline of the flame shakes rapidly at a frequency greater than 30Hz.

[0022] The present invention judges the state (combustion / extinguishment) of flame based on above-mentioned baker flame feature, as figure 1 As shown, the specific steps are as follows:

[0023] Step 1: Flame video image data collection.

[0024] The flame video is shot by the camera to obtain the current frame of flame image data, which is transmitted to the recognition board in Y...

Abstract

The invention discloses a visual identification method for flame detection of a ladle baking device. The method comprises the following steps: firstly, acquiring current frame flame image data; performing high-brightness contour calculation on the acquired current frame flame image data to obtain a flame contour array; performing contour similarity calculation on the flame contour array of the current frame and the calculated flame contour array of the previous frame; and finally, similarity calculation result processing is carried out. By adopting the method, the instrument is not in direct contact with the flame, so that the instrument cannot be influenced by damage factors such as high temperature, high impact and chemical oxidation of the industrial flame; and the instrument is simpleand convenient to install, the installation mode is consistent, and the on-site process structure is not changed.

Description

technical field [0001] The invention belongs to the technical field of embedded visual recognition, and specifically relates to a method for detecting the flame of a baker in the metallurgical industry. The visual recognition technology is used to judge the burning state of the flame. Background technique [0002] The baker is the main production equipment in the metallurgical production process. It is used to bake the ladle and needs to run continuously for a long time. The flame state (burning / extinguishing) of the baker directly affects the production rhythm and production safety. The flame detection device is the The key component of the controller control system. [0003] The existing visual recognition method for flame detection of bread bakers uses temperature difference detection or plasma detection as the basis for judging the flame state. Both detection methods must be in close contact with the flame, and the detection components are prone to failure, and the maint...
