On September 13, the Mid-Autumn Festival, when the whole nation was immersed in the happy atmosphere of family reunion, at 5:30 p.m., a "whine" alarm sounded in the emergency command center room of forest fire prevention of Yangxin County Forestry Bureau of Huangshi City. Xiaoxu, on duty, checked the research and development of Shenzhen Yungan Internet of Things Technology Co., Ltd. Forest fire monitoring and early warning system automatically locates the fire in Zhongluo Village, Yanggang Town, Yangxin County. Because of the steep terrain of the fire zone and the dry weather, Xiaoxu, on duty, reports the fire information to the leadership in time. With the strong support of departments at all levels, the firefighters struggle hard because of the fire. In time, the fire was extinguished without causing casualties.

Yangxin County, located on the South Bank of the middle reaches of the Yangtze River, has a forest area of 59,155.1 HA and a total standing stock of 2,320,300 m3. It is a key county for poverty alleviation and development and national forest fire prevention. In the past, the forestry bureau of Yangxin County used traditional video surveillance and personnel patrol to monitor forest fires. Fires happened more than 20 times a year. There were more than a dozen forest rangers in a forest area. The intensity of labor of the staff was high. When the fire happened, it often could not be detected in time. It took 2-3 hours to respond to the fire, and the early warning methods were backward.

Yangxin County Forestry Bureau successfully applied the forest fire prevention monitoring and early warning system developed by Shenzhen Yungan Internet of Things Technology Co., Ltd. in 2018. Eight dual-spectral infrared thermal imaging cameras were installed in Yanggang Town and Longgang Town for early warning and monitoring of forest farms. Each camera has a detection distance of 5 kilometers, and has been installed and used up to now. The fire occurrence rate decreased by 95% in the same period. The fire response time only needs tens of seconds, and can accurately locate the longitude and latitude of the fire point. The positioning accuracy can reach up to tens of meters.

Forest fire prevention monitoring and early warning system is independently developed by Shenzhen Yungan Internet of Things Co., Ltd. with core intellectual property rights, and has obtained a number of software copyright and utility model patents. The successful application of the system in Yangxin Forestry Bureau breaks through the traditional way of video surveillance and personnel patrol to monitor forest fires, breaks the phenomenon of "information isolated island", forms the interconnection and interoperability of forest fire prevention information among departments of cities and counties, perfects the early warning and monitoring network of forest fire prevention in Yangxin County, and realizes forest fire prevention. Scientific rescue, informationization of communication command, standardization of early warning response and scientific decision-making have greatly improved the efficiency of early warning and effectively protected the forest and ecological resources in Yangxin County.
