1. System overview

Forest fire is a serious natural disaster, which will not only cause damage to the ecological environment, but also threaten the safety of human life and property. With the advancement of afforestation in China, forest fire prevention is particularly important. Effective forest fire prevention requires early detection, early warning, and early disposal to reduce the losses caused by fires.

With the help of modern technology, PTZ cameras have become a key piece of equipment in forest fire prevention systems. Not only do they enable round-the-clock remote monitoring, but they also provide efficient fire detection and real-time alarms in complex forest environments. The application of PTZ cameras in forest fire prevention has completely changed the limitations of traditional manual monitoring and brought significant technical upgrades to forest management.

2. System architecture

The system consists of three parts: front-end camera, power supply system, wireless/wired transmission system, and back-end analysis platform. The pyrotechnic intelligent identification system has been optimized, which greatly improves the accuracy of intelligent identification.

3. System functions

All-weather monitoring: The system is equipped with advanced intelligent monitoring equipment to monitor the forest area 24 hours a day. The high-performance camera with low-light day and night capability provides clear images in different light conditions, ensuring all-weather monitoring without blind spots.

Efficient fire detection: The system uses a 2 million pixel high-definition camera, combined with intelligent pyrotechnic recognition algorithms, to accurately detect smoke and flames at a long distance (more than 10KM). After the initial identification, the information is sent back to the back-end analysis platform for secondary confirmation, which greatly improves the accuracy of fire detection.

Rugged equipment: Equipped with a heavy-duty outdoor intelligent PTZ camera, with a payload of more than 50 kg, with an automatic constant temperature system and intelligent analysis linkage function, it can operate stably in bad weather (such as strong winds, heavy rains, etc.) to ensure the continuous reliability of monitoring equipment.

Autonomous power supply system: The front-end equipment can be equipped with a wind-solar hybrid power supply system, which is suitable for field environments without mains power supply. Energy saving can be activated in rainy weather

Efficient wireless communication: The system adopts industrial-grade 5.8G wireless microwave communication technology, providing a bandwidth of up to 150Mb/s and a transmission distance of up to 20KM. By adding relay equipment, it can cover a range of up to 120KM, and the core transmission module can be infinitely expanded to ensure the stability and efficiency of data transmission.

Back-end intelligent analysis: The back-end server has a powerful secondary analysis function, which further improves the accuracy of pyrotechnic identification and reduces false positives and false negatives through in-depth processing of backhaul data.

GIS map linkage command: The command platform adopts GIS map linkage mode to intuitively display the location of front-end monitoring points and monitoring screen areas. In the event of a fire, it can be quickly revealed the location of the fire, the spread of the fire, the material reserve and the call information, combined with the personnel positioning system, improve the command efficiency.

Hierarchical authority management: The command platform has 256 levels of authorization, which is convenient for commanders and managers at different levels to obtain real-time data support. In daily cases, the situation of the forest area is checked in real time through the internal office network or the Internet to ensure that the fire prevention policy of "prevention first, active fighting" is implemented.

Multi-departmental collaboration: The system can provide real-time video data to higher-level authorities and other relevant departments such as forestry, natural environmental protection, animal and plant protection, etc to expand the application scope of the system and improve the ability of multi-department collaboration.

4. System advantages

Intelligent PTZ camera: The heavy-duty intelligent PTZ camera independently developed by Kangfez can intelligently identify fireworks and send the preliminary information back to the monitoring center for secondary analysis, which greatly improves the accuracy of recognition.

High-resolution camera: The use of 2 million pixel network HD camera, greatly improving the image resolution, can find the fire at a distance of more than 10KM.

Fog penetration: The image resolution under fog conditions is improved to ensure the reliability of smoke and fire recognition.

Rugged PTZ camera: with a strong load capacity, automatic constant temperature and intelligent linkage function, it can operate normally in extreme weather conditions.

Intelligent identification of pyrotechnics: After the initial identification, the PTZ camera will magnify the image and transmit the information to the back-end analysis platform, and automatically resume the cruise state if it is confirmed that there is no fire, effectively reducing the false alarm rate.
