Abstract:

Tunnel construction is being increased rapidly in Korea. About 60 percent of total tunnels have been constructed for the last 10 years. So systematic tunnel measurement and maintenance system have been needed. Vibrating wire type sensor is widely used in tunnel measurement system because of their stabil-ity and durability. Vibrating wire element is applied strain gauge, earth pressure cell, temperature gauge, piezometer and so forth. But conventional vibrating wire sensor is using wire-based communication and many problems have been occurred like high cost and disconnection. So we developed low-cost and effective wireless communication module for vibrating wire type sensor using pulse counting and Zig-bee technologies. This module can change conventional wire-based data log and communication into wireless one instantly. This paper describes prototype of wireless communication based vibrating sensor system and results of field test.
