Smoke thermal imaging fire automatic positioning detection system and method

The invention provides a smoke thermal imaging fire automatic positioning detection system and method. All photoelectric smoke detectors are encoded through an encoder, the position serial number of each detector is made to correspond to a thermal imaging view field, and thus the specific position of a fire can be determined. A thermal imager is used for monitoring the field, the fire behavior can be discovered earlier compared with a common video detector, and the system and method are particularly suitable for hazardous places such as aircraft cargo spaces, nuclear power stations and high voltage transformer substations where people cannot enter easily. When a smoke alarm gives out a fire alarm, at the moment, if no excessive heat video areas are captured by the thermal imager, the fire alarm can be removed, and accordingly loss caused by a fake fire alarm can be lowered. The multi-working mode and multi-interface design is adopted, the practicability can be improved, and equipment transformation in the later period is facilitated. Smoke signal detection and thermal image detection are combined, an intelligent information processing method is used for detecting and positioning fires, and accordingly the intelligence of fire fighting equipment is promoted. The place where the smoke alarm has already been mounted can be upgraded and reconstructed, and the robustness of a detection result can also be improved.
