Fire is a serious natural disaster affected by weather conditions and ecological environment, with strong suddenness, great destructive power, and difficult firefighting. Traditional fire monitoring is mainly based on observation towers, supplemented by cruise aircraft and satellite monitoring. In large areas, fires are often caused by inconspicuous hidden fires. It is difficult to detect such hidden fire signs with existing ordinary monitoring systems. Therefore, the biggest advantage of using infrared thermal imagers compared to ordinary video surveillance methods is that they do not require visible light support. This greatly facilitates early detection and prevention of fires in areas limited by light or during nighttime detection, and greatly reduces the cost of fire prevention work.

Plan Overview:

Forest fire warning, monitoring and command solution applied by Haohai TechnologyLin Hai GuardianandNight Eye SeriesVideo surveillance products and related productsVideo surveillance and contingency management command software platformUsing visible light fireworks recognition and thermal imaging temperature monitoring dual-mode detection, applying the thermal sensing characteristics of infrared thermal imagers, and conducting real-time monitoring and fire alarm within the monitoring area through GIS positioning. The front-end equipment has the function of fire recognition within a certain distance, which is transmitted to the software platform of the monitoring center through the network. The thermal imaging image of the management center will identify the highest temperature value within the monitored range on the image. If there is a fire alarm, it will be monitored at a designated location through GIS, pan tilt angle and other information. At the same time, fire alarm information can be sent to the on duty personnel to achieve fire alarm monitoring. This system can meet the functions of digital pan tilt control, geographic information system positioning, monitoring target hotspot detection, automatic fire recognition and alarm.

Scheme design:

1. Video capture system

The video capture system is the eye of the video surveillance system in key fire hazard areas. It inputs the system's discrimination signal through video capture of the monitoring area, and ultimately determines the fire situation through the system. The acquisition system consists of a visible light recognition system, an infrared recognition system, an electronic image stabilization module, a pan tilt zoom and cover system, which completes the video information acquisition task, provides clear and stable video image data for the subsequent processing system, and can achieve 360 degree full coverage. It can accurately determine technical parameters such as pitch angle and azimuth angle, and can achieve horizontal and pitch movements at various speeds.

2. Fire search system

The system has three search modes: turntable uniform rotation search mode, turntable step search mode, and high-precision search mode for key area coverage. By using image intelligent smoke recognition algorithm, the visible light and infrared images collected by the video capture system are analyzed to alert the fire and synchronously track the fire search in real time; Control the video capture system, zoom in on the image, and conduct a full coverage scan of the area where the fire occurred; It can achieve complementary discrimination between infrared and visible light, and has video processing capabilities such as image stabilization, denoising, and enhancement to improve the efficiency of fire search; Support flexible setting of parameters such as discrimination threshold to meet the needs of different environments and seasons. The fireworks recognition engine adopts a dynamic cruise scanning and static recognition secondary mechanism for fireworks recognition and alarm.
