At the beginning of 2020, Dahua Technology provided an intelligent forest fire prevention monitoring system for Rizhao. This solution gives an automatic early warning of fire, real-time fire control and closed-loop response through digital intelligence technology, significantly improving forest fire prevention and dispatch.
Mountainous regions, like Rizhao in Shandong Province of China, are vulnerable to forest fires. Recognised by the United Nations in 2009 as one of the most habitable cities in the world, this city consists of 4,358 mountains, with a forest area of 1,400 square kilometers that account for 70% of the region.
Up until now, forest rangers have manually scouted and monitored the area, walking nearly 10 kilometers of treacherous trails for several hours a day.
The Illegal wood burning in the area, if not controlled properly, can lead to a disastrous wildfire. According to a World Health Organization report, in 50% of wildfires recorded, the cause that triggered them is unknown.
At present, high-altitude dual-lens thermal imaging cameras cover the main mountains in the city, carrying out 360 ° remote monitoring 24/7. This solution also offers real-time sensing and intelligent management of people and vehicles coming in and out of the forest areas.
Furthermore, to reduce false alarms, the system adopts algorithms for deep smoke and mountain scanning, thus improving the accuracy of real fire alarms and saving manpower and material resources.
After half a year of operation, the system has detected more than 30 real mountain fires. The average number of fires found every day during fire season has significantly decreased by 80% compared with the initial stage of the project. This reflects the effectiveness of the solution in fire monitoring and the increasing awareness of villagers regarding fire safety.
Overall, this solution helps guarantee the safety of 1,400 square kilometers of forest resources in Rizhao.
