| Abstract: | The leakage monitoring system composed of sub-stations along multi-point distributed pipelines and monitoring center was designed.The monitoring sub-stations can detect the pressure of segmental pipelines based upon sensors installed there,and can send the data to remote monitoring center via GPRS network to realize unattended monitoring in field.The real-time dynamic amendments to negative pressure wave speed and synchronization timing operated by monitoring center were introduced in data analysis and processing that can make the system have higher responsible speed and location precision in reducing distort rate. |
