Abstract

The invention discloses a double-wave band image identification fire detection alarm system and the monitoring method thereof. Solving the problem that current image alarms are likely to give wrong warning, invention has the advantages of simple structure, convenient use, and high alarm accuracy. The structure is as follows: The system at least includes a detector and a power source. The detector is a double-wave band image detector; the output end of the detector is connected with a video distributor, whose one output is connected with the normal circuit monitoring system, and another output connected with an image collection device. The image collection device is connected with a computer, which is connected with a linkage controller. The linkage controller is connected with alarm and rescue devices separately.

Description

technical field [0001] The invention relates to an alarm device, in particular to a dual-band image recognition fire detection alarm device and a monitoring method thereof. Background technique [0002] With the rapid development of my country's economy, a large number of new, large, high-rise, underground and other large space buildings have emerged, and the scale of storage has been expanding day by day. The traditional method of fire prevention facilities inside the building is to use temperature, smoke, photosensitive detectors and infrared camera detectors. However, for large-space buildings and open-air places, the traditional detection methods can no longer meet the fire-fighting requirements of these places. For large-space buildings with monitoring equipment installed, if the fire detection can be carried out by analyzing and identifying the image information collected by the camera, it will not only effectively overcome the shortcomings of traditional detectors in ...
