Paper Abstract

In this paper we present multi-point vibration sensor using a 12-fiber telecommunication cable. This complex sensor can be used to monitor the state of large objects such as pipes, bridges, buildings, etc. The main advantage of the proposed solution is to use low-cost telecommunication components to reduce the cost of the entire system and make it competitive with very expensive OTDR methods. The system is also able to on-line monitor state of the object. The paper shows a draft model of the system architecture and the results of initial laboratory tests. We showed the possibility of detection and localization of periodic vibrations and single hits. Also we have shown the ability to monitor shape changes of the pipe due to any slow deflections. The very advantage of this system is capability of indicating the direction of deflection.
