A new generation of intelligent fire monitoring and command management system developed based on years of practical experience, integrating advanced high-tech means from multiple disciplines.

Fire is a highly destructive disaster that endangers forest resources, poses a serious threat to human living environment, and is difficult to deal with. It is also an important factor affecting sustainable economic and social development. China is one of the countries with a high incidence of forest fires. Due to natural and historical reasons, the frequency of fires is relatively high, and the losses caused to forest resources and ecological environment are difficult to estimate. Meanwhile, due to various factors such as abnormal climate, accumulation of combustibles in forest areas, and increased outdoor fire sources, the risk of forest fires has increased, posing more challenges to the forest fire prevention work of the forestry department.

The Wenlang Forest Fire Prevention Intelligent Monitoring and Command Management System is a new generation of intelligent fire prevention monitoring and command management system that integrates advanced high-tech means in multiple disciplines such as video processing, heat source detection, image recognition, computer software, satellite positioning, mobile communication, microwave transmission, etc. It is developed based on years of practical experience in forestry fire prevention. With video monitoring as the foundation and fire alarm as the core function, it also extends additional functions such as geographic information system, command decision-making, personnel positioning, vehicle monitoring, meteorological information collection, ecological construction and management. It can achieve real-time, comprehensive and accurate monitoring of forest fires, and provide strong support for forest government management, ecological management, and daily management work of forestry departments.

● Intelligent recognition and warning of forest fires

Forest fire recognition can support two methods: smoke detection based on image recognition and forest fire detection based on infrared thermal imaging.

•Real time analysis of monitoring images and heat source detection data to ensure timely detection and identification of fire situations, and sending alarm information to the monitoring center;

•The fire recognition module is located at the front end of the monitoring point, which can truly achieve real-time analysis while reducing network transmission pressure;

•Recognition parameters such as threshold can be manually adjusted to adapt to different environments and ensure the accuracy of alarms;

•The software self-learning function automatically adjusts analysis parameters and improves the accuracy of alarm analysis as the system runs and data accumulates;

•After discovering a fire, an alarm is triggered and recorded. The front-end gimbal automatically adjusts the camera angle to focus the monitoring image on the location of the fire, reminding the on duty personnel to check the display screen and detect the fire and its location early;

•Real time sound and light alarms in the monitoring center;

•Mobile alarm, the alarm information is sent in real-time to all relevant personnel's mobile phones;

Geographic Information Systems and Command Management

The combination of geographic information systems (electronic maps) and real-time monitoring and alarm functions enables real-time and intuitive display of forest fire alarms on maps, as well as dynamic management of forest fire prevention work, while providing intuitive decision support for fire prevention.
