The distributed monitoring system for transmission line nearby wildfires are studied in this paper. The visible /infrared thermal imaging data are detected by the remote terminal

which is installed at the fire risk area. The data are transferred to the background management system by GPRS wireless commucication channel and the fire spots are automatically identified

realizing the close range and real-time monitoring and alarm of wildfires. This paper provides a new method for transmission line nearby wildfire monitoring and early warning

and thus improves the prevention efficiency of wildfires. The application in ±800 kV Binjin Line shows the monitoring effect is good

which means it is worth popularizing and applying.Aiming at the two disadvantages of large energy consumption and weak wireless communication signal

wind & light complementary and high voltage mutual induction electric energy supply method and multimode communication module based on BEIDOU / CDMA / GPRS are proposed respectively

providing reference for further study and improvement.
