As a forest sentinel, the infrared dual spectrum pan tilt camera has achieved breakthroughs in multiple aspects such as dual-mode perception fusion, intelligent decision-making system, precise positioning capability, extreme environment adaptation, and air ground coordination system in technology, and has built an intelligent prevention and control system of "early detection, accurate positioning, and fast disposal".
1. Dual modal perception fusion: breaking through environmental limitations
Technological breakthrough: Integrating visible light and thermal imaging dual channels to achieve multi-dimensional perception of "temperature+morphology". The visible light channel supports 30x optical zoom, and the thermal imaging channel uses a vanadium oxide uncooled detector, which can capture small temperature rises of 0.1 ℃ and penetrate obstacles such as thick smoke and darkness.
Application effect: After deployment in Ailao Mountain, Yunnan, the early fire recognition rate reached 92%, and night monitoring had no blind spots; Fujian Shishi achieves effective monitoring for 3 kilometers, covering traditional blind spots.
2. Intelligent decision-making system: reducing false alarm rate
Technological breakthrough: Based on a deep learning model trained on over 100000 fire scene samples, the false alarm rate is controlled below 1% through dynamic parameter tuning technology. The accuracy of typical case recognition reaches 99.7%, and the model training cycle is shortened by 60%.
Application effect: In the application of Jilin Forest Farm, the fire detection time has been shortened from 2 hours to 15 minutes, and the false alarm rate has decreased by 76%; The straw burning fire in a town in Shandong Province has decreased by 80%.
3. Accurate positioning capability: improving response efficiency
Technological breakthrough: Integrating 3D GIS and Beidou positioning module, compressing the coordinate error of the fire point to within 10 meters, and combining laser ranging technology to achieve 3D modeling of the fire scene.
Application effect: Jilin Forest Farm covers a radius of 8 kilometers with a single tower, replacing 3-5 manual inspection points; A 200 kilometer monitoring zone has been established in the Greater Khingan Range, with a maximum daily processing of 1385 thermal anomaly signals.
4. Adaptation to Extreme Environments: Ensuring Stable Operation
Technological breakthrough: The device has passed IP68 protection certification, withstands immersion in 2 meters of water and 12 level wind pressure testing, supports wide temperature operation from -40 ℃ to 70 ℃, and the heavy-duty gimbal supports 360 ° rotation and wind resistance design.
Application effect: When a coastal defense post on one side of the South China Sea is hit by typhoon and rainstorm, the equipment will continue to work stably to detect and warn the approaching ships in time.
5. Collaborative system between land and ground: building a three-dimensional prevention and control network
Technological breakthrough: Linking with drones and radar to form a closed loop of "fixed-point monitoring+mobile verification". The Taiyuan Scenic Area in Shanxi Province has deployed a "land to ground linkage" monitoring network, and the Yinxi Street in Fuqing has integrated high-altitude cameras and unmanned aerial vehicle systems.
