The regular inspection of power lines is a vital task for the power grid operation and maintenance management department. Now days, Using UAV mounted long range real time video downlinks to do the inspection is a advanced way to achieve high efficiency.

Pipelines are the primary means of the distribution of oil and gas resources. The area where the oil and gas pipeline is located has the characteristics of long distance and wide range. These areas are often complex in geography such as large reservoirs, lakes and mountains. Especially when the pipeline crosses the edge of the original forest, high altitude and snow-covered areas the traffic and communication are extremely underdeveloped and geological disasters such as mudslides and landslides along the line also often occur. Therefore, routine manual inspections in these areas are difficult to achieve.

Unmanned Aerial Vehicle, abbreviated as "UAV", is a non-manned aircraft operated by radio remote control equipment and independently developed program control devices or operated by the onboard computer autonomously or intermittently. Compared to ordinary pilot aircraft, UAVs are more suitable for dangerous missions. UAVs can be divided into military and civilian drones depending on the field of application.

Natural disasters usually happen suddenly. The key to disaster emergency rescue is the rapid response after happening. Timely and accurate disaster information plays a vital role in timely formulating rescue strategies and improving rescue efficiency and rescue quality.

How to effectively use high-tech means to solve forest resources surveys, forest fire prevention and other issues has become the top priority of forestry work. At present, more new technologies and new equipment have been applied in forest fire prevention in foreign countries.
