Dahua Technology’s fire prevention solution helps protect mountainous region of Rizhao in China against forest fire

A forest fire (also known as wildfire) is an unplanned and uncontrolled fire in an area of combustible vegetation, such as forest, grassland or prairie. It is often caused by human activities or natural phenomenon, like lightning. Nevertheless, according to a World Health Organization report, in 50% of wildfires recorded, the cause that triggered them is unknown.

Mountainous regions, like Rizhao in Shandong Province of China, are vulnerable to forest fire. 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 kilometres that accounts for 70% of the region. The illegal wood burning in the area, if not controlled properly, can lead to a disastrous wildfire.

Monitoring and spotting fire sources in time

For decades, forest rangers manually scout and monitor the area, walking nearly 10 kilometres of treacherous trails for several hours a day, in order to safeguard the forest against threats like wildfire.

However, this arduous method of patrolling is inefficient, as it will be difficult to respond in time, in case of emergencies. As their first line of defence, they need a robust solution that can monitor and spot fire sources in time to prevent possible forest fire.

Intelligent forest fire prevention system

At the beginning of 2020, Dahua Technology provided an intelligent forest fire prevention monitoring system for Rizhao

At the beginning of 2020, Dahua Technology provided an intelligent forest fire prevention monitoring system for Rizhao. This solution realises automatic early warning of fire, real-time fire control and closed-loop response through digital intelligence technology, significantly improving forest fire prevention and dispatch.

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.

Integration of AI and thermal imaging technology

Forest fires are often difficult to detect in deep mountains and forests with high vegetation, which often causes late detection and response. Through the integration of AI algorithms and thermal imaging technology, fire detection time is shortened, allowing the device to detect smoke and fire source within a radius of nearly 10 kilometres.

The fire’s location, intensity, and surrounding conditions are initially determined and sent to the operator’s mobile phone, allowing relevant personnel to respond in time, within the ‘golden time’ of extinguishing early fire.

Algorithms for deep smoke and mountain scanning

Furthermore, in order to reduce false alarms, the system adopts algorithms for deep smoke and mountain scanning, thereby improving the accuracy of real fire alarms and saving manpower and material resources.

Fire prevention personnel are no longer exhausted of their daily duties, which helps boost their enthusiasm at work.

Forest fire prevention platform

This solution also includes a forest fire prevention platform that operators can use to check for any fire situations

In addition, this solution also includes a forest fire prevention platform that operators can use to check for any fire situations. It can also guide them for effective decision making and timely dispatch of personnel to the scene, achieving a closed-loop management of fire prevention – from discovery, dispatch and feedback.

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%, when 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.

Dahua solution enhances Rizhao’s fire safety

The Dahua solution has improved Rizhao’s forest protection and fire prevention system, and has also realised the co-construction and co-sharing of resources during fire season and non-fire season. The implemented solution provides data that are beneficial for various departments and agencies, such as environmental protection, water conservation, maritime bureau, etc.

Overall, this intelligent solution helps guarantee the safety of 1,400 square kilometres of forest resources in Rizhao, a lively city also known as the ‘City of Sunshine’.
