Embodiment 1

[0030] like figure 1 Shown, a kind of fire monitoring method, described fire monitoring method comprises the steps:

[0031] Step S1: Detect the fire monitoring area, and collect video images of visible light sources;

[0032] The step S1: detecting the fire monitoring area, and performing video image acquisition on the visible light source is specifically: performing real-time temperature scanning detection on the fire monitoring area, when the temperature in the fire monitoring area rises abnormally, the abnormal temperature rise in the fire monitoring area Visible light source in high area for video image acquisition.

[0033] By setting the fire monitoring image acquisition camera host in the fire monitoring area, and then configuring residual current detectors and temperature detectors to detect the fire monitoring area in real time, the thermal radiation data, smoke diffusion data and temperature field distribution of visible light sources can be obtained data. When t...

Embodiment 2

[0049] like figure 2 Shown, a kind of fire monitoring method, described fire monitoring method comprises the steps:

[0050] Step S1: Select standard fire flame color characteristics, fire flame shape change characteristics and change frequency to set up a standard fire flame characteristic database.

[0051] A fire monitoring method based on image processing, which uses a camera to monitor the scene, and at the same time converts the continuous images captured by the image acquisition card into digital images input to the computer for continuous image processing and analysis, through the shape and color of the early fire flames Change signature to detect fire. Therefore, it is necessary to select the standard fire flame color characteristics, fire flame shape change characteristics and change frequency to set up a standard fire flame characteristic database, and obtain the visible light source characteristics and standard fire flame characteristic database by processing and...

Abstract

The invention discloses a fire monitoring method and a fire monitoring system. The fire monitoring method comprises the following steps of detecting a fire monitoring area, performing video image acquisition on a visible light source; transmitting data of the video image of the visible light source to a monitoring center; performing image processing and analysis on the color change characteristic and the shape change characteristic of the visible light source in the video image of the visible light source; and comparing the color change characteristic and the shape change characteristic of the visible light source with standard flame characteristics of the fire, thereby determining whether fire occurs. Through the steps of the method, the fire monitoring method and the fire monitoring system can perform functions of reducing fire monitoring cost, shortening fire detecting period, improving reliability of the fire monitoring system, reducing number of fire detectors and firefighting equipment, and simplifying use and maintenance of the fire monitoring system.

Description

technical field [0001] The invention relates to the technical field of fire detection, in particular to a fire monitoring method and system. Background technique [0002] At present, the fire monitoring and detection system is divided into detectors, analysis systems, and emergency response systems. Detectors are usually divided into three types: smoke-sensing, light-sensing and temperature-sensing. The analysis system is based on the data detected by the front-end detectors. situation, and then implement countermeasures. The disadvantages are that the building scale is huge, the number of fire detectors and fire-fighting equipment is large, and if a single fire house is incorporated into the host, there will be disadvantages such as complex and huge application software, long fire detector inspection cycle, reduced reliability of the fire monitoring system, and inconvenient use and maintenance. Contents of the invention [0003] In view of the above-mentioned deficiencie...
