With the continuous development of forest protection and forestry construction, the area of forest land and forestry stock in China have been increasing year by year, but the task of fire prevention is also increasing day by day. Forest fires are sudden and random, and can cause huge losses in a short period of time. Therefore, whether the discovery of forest fire behavior is timely, the analysis is accurate and reasonable, and the decision-making measures are appropriate are closely related. Daily aircraft carry out fire inspection tasks, and once a fire is detected, they can be put into firefighting work. Therefore, aircraft generally have large tonnage, strong loading capacity, and complex task execution.

The photoelectric pod for forest fire prevention generally requires the ability to provide visible light and infrared images, as well as functions such as recording geographic information of fire points, calculating fire area, and analyzing fire situation. It can provide reliable decision-making basis for ground firefighting command, and also requires the ability to clearly and intuitively display high temperature fire points on the ground. It is also required to monitor residual and hidden fires after extinguishing to prevent recurrence.
