Embodiment Construction

[0023] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The following examples are intended to illustrate the present invention, but not to limit the scope of the present invention.

[0024] like Figure 1 ~ Figure 4 As shown, the present invention provides an effective method for online real-time intelligent detection and early warning of a public pipe gallery in a chemical park, comprising the following steps:

[0025] S1. Use a binocular system composed of an uncooled infrared camera and a visible light camera to monitor the public pipe gallery in the area and collect video signals in the preset monitoring area;

[0026] S2. Use smoke detection and gas leak identification algorithms for detection;

[0027] S3. Use visible light and infrared image fusion technology to determine the leakage point of pyrotechnics and gas, and generate an alarm.

[0028] Preferably, the co...

Abstract

The invention discloses an intelligent smoke detecting and early warning method. The intelligent smoke detecting and early warning method includes the following steps of monitoring monitored objects in an area and collecting video data by using a binocular system composed of a first image acquisition device and a second image acquisition device, detecting a smoke and fire area and the gas leakage situation according to the video data, and determining the smoke and fire area and the gas leakage point and giving out an alarm with the visible light and infrared image fusion technology. An effective on-line real-time intelligent detecting and early warning method for public pipe galleries of a chemical industrial park is provided by combining the image processing technology and the pattern recognition technology. Through the network technology and the system design, all the public pipe galleries of the whole chemical industrial park can be monitored on line in real time and an alarm can be given out timely when gas leakages and smoke and fire accidents happen.

Description

technical field [0001] The invention relates to the technical field of image processing and pattern recognition, in particular to a method and device for intelligent detection and early warning of smoke. Background technique [0002] The modern chemical industry has entered a highly automated production process. Most of the equipment is in a state of process operation and long-term operation, and some even operate in a high temperature, high pressure and corrosive environment, which is inflammable and explosive. . Therefore, the monitoring of major equipment in the production process is very important, and it has extremely important practical significance for the detection and early warning of gas leaks in the chemical industry park. [0003] At present, most of the video-based detection methods are relatively simple, only for fire detection or gas leakage detection, and there are relatively few researches on the application in the special environment of chemical industry p...
