1. System overview
Forest fire is one of the world's natural disasters. With the continuous development of China's afforestation industry, fire prevention has become the primary task. Forest fire prevention must implement the policy of "prevention first and active rescue", and truly achieve early detection and early resolution. At present, the remote wireless monitoring system based on wireless network technology has been widely used in the field of forest fire prevention monitoring.
Mingjing forest fire prevention and early warning system is improved and upgraded by the company's experienced engineers and technicians after 2 years of hard research and development on the basis of the existing forest fire prevention system on the market. Taking into account the principles of system reliability, practicability and scalability. The flat and modular system architecture greatly improves the reliability of the forest fire prevention and early warning system, and greatly reduces the system's failure rate and false alarm rate..
2. System architecture
The system consists of three parts: front-end camera, power supply system, wireless/wired transmission system, and back-end analysis platform. Optimized the pyrotechnic intelligent recognition system, greatly improving the accuracy of intelligent recognition.
3. System function
★This system uses advanced intelligent monitoring equipment to carry out all-weather remote monitoring and monitoring of the forest area, avoiding the limitation of the original artificial lookout observation of the fire, realizing the digital and scientific management of the forest area, and greatly reducing the cost of the forestry department Expenditure and management costs increase the effectiveness of forestry enterprises.
★Equipped with 2 million pixel low-illumination day and night professional cameras, it can detect fire from a long distance.
★Equipped with a heavy-duty outdoor intelligent PTZ camera, the effective load is greater than 50 kg, with automatic constant temperature system, intelligent analysis linkage function. It can effectively resist strong convective weather such as strong winds and heavy rains. Stable operation in extreme weather.
★Equipped with front-end wind-solar complementary power supply system (optional). Long-term stable operation in a field environment where mains power cannot be used. The energy-saving mode can be activated in rainy weather to ensure the normal operation of the system for 30 days.
★Equipped with industrial grade 5.8G wireless microwave communication system. In the field, it can stably transmit a distance of more than 20KM with a bandwidth of 150Mb/S. Adding relay equipment can cover up to 120KM range. After adding the core transmission module, the transmission range can be expanded unlimitedly.
★The back-end server has a secondary analysis function. Greatly improve the accuracy of firework recognition.
★The forest fire prevention and early warning command platform uses GIS map linkage to intuitively display the location of the front-end monitoring point and the current picture display area on the topographic map.
★In the event of a fire, it can quickly show the location of forest fire alarm, the spread of fire, the location of material storage, and the situation of material deployment. After installing the personnel positioning system, the current personnel location and related information can be superimposed on the map. Visually show the development of forest fires and the situation of rescuers. Effectively improve the efficiency of command operations.
★Classified viewing function. The command platform has 256 authorization levels, which can conveniently provide real-time and effective data support for commanders and management centers at all levels. In daily situations, commanders and management centers at all levels can conveniently check the situation of the forest farm at any time through the internal office network or the Internet, and achieve "prevention first and active rescue".
★At the same time, through the hierarchical viewing function in daily life, you can provide on-site real-time video data to supervisors and other forestry, natural environmental protection, animal and plant protection departments. Expand the scope of use.
4. System advantages
★The heavy-duty intelligent PTZ camera independently developed by Mingjing Company is used in the front end to realize the intelligent identification of the camera's fireworks and return it to the monitoring center. The fireworks information initially found by the camera is transmitted back to the control center through the transmission system. The secondary analysis is performed by the control center. Greatly improve the recognition accuracy.
★Using a 2 million pixel network high-definition camera, which greatly increases the image resolution, and can accurately detect the fire at a longer distance (over 10KM).
★The camera has a fog penetration function, which can effectively improve the image resolution and avoid the influence of mountain fog on the recognition rate of fireworks.
★Using heavy-duty outdoor intelligent PTZ camera, the effective load is greater than 50 kg, with automatic constant temperature system, intelligent analysis linkage function. It can effectively resist strong convective weather such as strong winds and heavy rains. Stable operation in extreme weather.
★The PTZ has a firework recognition function. After preliminary identification and judgment, the PTZ will zoom in on the image, and the information will be sent to the back-end analysis platform for secondary analysis. If it is judged that it is not a fire, the cruise state is automatically restored. Effectively reduce the false alarm rate.
