Abstract: Through the analysis of the present situation and the actual demand of Qinghai-Tibet Railway tundra data acquisition, this paper has proposed the overall project design scheme of long-distance wireless automatic monitor system and described the system function, the composition structure and the project implementation in detail. It has been proved through practice that the system fundamentally solved the manual data acquisition problem in Qinghai-Tibet Railway.

Key words: qinghai-Tibet railway, automatic monitor, tundra, tundra temperature gathering
