Telephoto lens long-distance monitoring scheme Forest fire protection application

Because fires are often located in deep mountains and old forests, it is difficult to find them, so finding fires is of great significance for early extinguishing of fires. There are still many ways of backward technology in China. The lack of observation platform monitoring: its observation effect is limited by the terrain and terrain, the cover surface is small, there are dead corners and blanks, and it is impossible to observe it. It is impossible to go up the tower for observation; observation is a method of observation relying on the experience of the observer, with low accuracy and large error. In addition, the safety of the observers was threatened by lightning, wild animals, etc. The video surveillance system is a simple extension of traditional urban surveillance. The collected video images are aggregated by microwave, and the centralized surveillance is done manually; manual surveillance is easy to cause fatigue of the naked eye, and the fire in the video is not easy to be detected, which constitutes a false alarm; therefore, the traditional video The biggest flaw of monitoring is that the false negative rate is very high. In view of the shortcomings of the previous traditional monitoring plan, the long-distance overnight monitoring and early warning system recommended by this plan adopts the remote-distance fog-penetrating camera system and the far-infrared thermal imaging system to complete the remote-distance day and night monitoring. The system imaging technology requires stable performance and does not Affected by weather and environmental factors, it can work normally in daytime, rainy and foggy weather, and dark night. The telephoto security lens collects efficient video image information for 24-hour seamless monitoring, and the management area is suspended around the clock, with monitoring points of 3 kilometers and 5 Effective monitoring at intervals of kilometers, 8 kilometers, and 10 kilometers.
