Remote fire detection system and method based on video image

Abstract

The present invention discloses a remote fire detection system and method based on a video image. The system comprises: an image collection module configured to collect infrared images through a dual-band video collection technology and transmit the infrared images to a control module through a video decoder according to the features of the imaging of an infrared camera; the control module configured to achieve feature extraction for the infrared images through a DSP, perform flame recognition for the extracted image features through a recognition algorithm and upload a recognition result to aremote control center; a network communication module, wherein the control module is connected with the remote control center through a physical layer transceiver and a network interface in the network communication module, if fire occurs, the remote control center issues a control command to achieve an Ethernet communication function through the network communication module; and a wireless remote alarm module configured to achieve wireless network remote alarm. The remote fire detection system and method based on the video image improve the accuracy, the sensitivity and the reliability of the flame recognition algorithm and provide an effective method for large-space remote fire detection.

Description

technical field [0001] The invention relates to the field of fire flame detection, in particular to a remote fire detection system and method based on video images. Background technique [0002] At present, traditional fire detectors mainly include smoke detectors, temperature detectors, combustible gas detectors and infrared radiation detectors, etc. However, these detectors generally only play a role in urban buildings. Smoke detectors generally issue an alarm after the detected smoke reaches a certain concentration, which cannot make accurate fire predictions, and is also prone to false alarms and missed alarms. Temperature detectors, which use analog switch-type temperature-sensing elements, generally lose their benefits below 68°C, and at the same time cannot display and predict the current temperature value and the rate of temperature rise. Other fire detectors are more or less There are few external interference factors. At the same time, when the detection space be...
