Embodiment 1

[0078] The specific implementation of this patent is described by taking video intelligent identification and monitoring of fire smoke caused by leakage of tank area in refinery area as an example.

[0079] Step 1. Determination of static characteristics of fire smoke

[0080] First, the current frame image is obtained through the acquisition and input of video images, and then the irregular characteristics of the fire smoke boundary area and the gray level uniformity of the fire smoke area are delineated at the same time, and whether there is a suspicious fire smoke area is judged by carrying out.

[0081] The specific judgment method is as follows:

[0082] During the combustion process, the fire smoke will show an obvious tendency to spread, resulting in obvious irregularities in the smoke profile. Moreover, the perimeter of the fire smoke boundary is obviously larger than the perimeter of the circle with the same area. Using the characteristic of fire smoke, the followin...

Abstract

The invention discloses a fire smog video intelligent monitoring and early warning system and an early warning method, and relates to the technical field of fire smog monitoring in chemical plant areas. It includes a main server and an analysis and processing module. The analysis and processing module analyzes the video image in the main server, uses the static characteristics of the fire smoke in the video image to delineate the range of suspicious smoke, and then uses the dynamic characteristics of the smoke in the video image to detect suspicious smoke. area determination. When the video image shows irregular fire smoke boundary areas or / and the gray value of pixels on the fire smoke area, it is classified as delineation of suspicious fire smoke areas under static features. In the delineation process of the suspicious fire smoke area, the present invention comprehensively considers the boundary irregularity of the fire smoke area and the uniform gray level of the area, and can more effectively and accurately delineate the suspicious fire smoke area.

Description

technical field [0001] The invention relates to the technical field of fire smoke monitoring in chemical plant areas, in particular to a fire smoke video intelligent monitoring and early warning system and an early warning method. Background technique [0002] The installation process in the chemical plant area is complex, the materials are highly dangerous, and there is a high-temperature and high-pressure production environment in the production process, which is prone to combustion and explosion of chemical raw materials and leakage. Relevant data show that fire and explosion are the most important factors causing casualties and property losses in chemical plant areas. Therefore, real-time monitoring, identification and early warning of smoke generated in the early stage of chemical plant fires is of great significance to prevent fire and explosion accidents in chemical plant areas. At present, the traditional fire detector mainly monitors and warns by detecting fire par...
