Most of the transmission lines in Inner Mongolia are set up in the grassland environment, with complex terrain and long lines, and the efficiency of manual inspection and recording is relatively low. In this case, there is an urgent need for a tool to replace manual inspection. We have designed and developed a networked intelligent base station based on energy autonomy. The network intelligent base station developed in this design includes, first, machine vision algorithm to achieve accurate landing, this paper proposes a UAV attitude estimation method based on visual sign detection. The second is LORa communication to achieve no 4G network transmission: in order to enable the relay intelligent base station to communicate smoothly in the grassland environment, timely data information back to the ground monitoring station, this paper adopts the LORa WAN-based communication scheme. The third is the scenery complementary technology to achieve energy autonomy: in order to make the inspection drone long-term endurance, intelligent base station can adapt to the harsh environment of the grassland, this paper adopts the energy autonomy scheme based on the scenery complementary technology. The fourth is the network-type intelligent base station to achieve relay-type transmission line inspection: in order to achieve grassland ecological monitoring and transmission line inspection, this paper adopts the network structure, the intelligent base station is distributed near the transmission line and grassland. According to the principle of point-to-point communication, the network structure of grassland ecology and transmission line control is constructed.
