[0002] An image-type fire detector, also known as a video fire detector or a visual fire detector, is an intelligent safety device that uses a camera to capture images and analyze the image content to detect fires. Different from traditional point-type smoke detectors or heat detectors, the image-type fire detector can provide a wider monitoring field of view. An ordinary image-type fire detector has only one infrared camera to identify flames, which is vulnerable to interference from external strong light, strobe light, etc., resulting in false alarms and affecting the accuracy of alarms.

[0007] Compared with the prior art, the beneficial effects of the present utility model are as follows: The product consists of a split housing, a flame detection device, which includes an infrared camera and a flame recognition camera, a control main board, a connecting board and other main components. The flame recognition camera mainly recognizes the shape of the flame, collects, analyzes and processes the flame shape information on site through flame image processing technology, and learns the on-site environment through the monitoring site. By learning, the collected data is matched and calculated with a complete mathematical model to select the best data scheme to detect various interference sources on site, ensuring the accuracy of the alarm. The other infrared camera recognizes infrared light. When the data collected by the two cameras are compared and calculated by the processor and meet the conditions, an alarm action can be taken to ensure the accuracy of the alarm.
