In view of the steam/water piping outside the boiler of thermal power unit, considering its spatial structure characteristics of long distance, large drop and the working conditions under high temperature, high pressure and flexible operation. On the base of the static and dynamic analysis of the structure, the key nodes and parameters of monitoring were selected, the method of sensor installation and debugging was put forward, which was easy to maintain and reliable. A distributed monitoring data acquisition and digital processing analysis system was developed. The monitoring results showed that the monitoring system ran stably and reliably, and the test data of each node could accurately reflect the structural state of the piping. The monitoring system has a strong engineering application value.
