Abstract:
1. A multi-wavelength video image fire detecting system comprised of a multi-wavelength video image fire detector, an alarm and indicate equipment, a setting and debugging system, a communication equipment, an area alarm and monitor system, and a pan & title and control system, said multi-wavelength video image fire detector being comprised of a color and near IR dual-mode camera, a color and B/W dual-mode camera, an image capture module, a processor and controller, an I/O module, a housing and a visible light and near IR view window, wherein: said image capture module is adapted for converting analog video images into digital images and processing the digital images through a filtering process; said processor and controller is responsible for fire recognition, switching control of said color and near IR dual-mode camera and said color and B/W dual-mode camera, pan and tilt control and back light control, and provides hovering and flying attitude adjustment controls when used in a UAV (unmanned aerial vehicle) for forest fire detection; said I/O module comprises a plurality of hardware and software interfaces and a power supply system for system internal and external communication; said alarm and indicate equipment is adapted for indicating pre-alarm, fire alarm, and failure; said setting and debugging system is adapted for setting sensitivity, selection of different types of detection zones and self learning; said communication equipment is for connection to local and remote alarm monitoring systems to upload image and fire probability and alarm information and to receive control information; said area alarm and monitor system is adapted for monitoring remote detectors, giving control commands subject to operator's requirements, providing a secondary image fire recognition algorithm.
