ABSTRACT:
A pipeline monitoring system includes a series of monitoring stations (20), each having a computer (68), magnetic pig position detector (24), one or more input/output modules (90) and communications module (86). The communications module is operable to transmit data over a communications network from a remotely located monitoring stations (20) to a central monitoring facility (50). Commands transmitted from the central monitoring facility or events generated by the passage of a magnetic pig cause the monitoring station to automatically perform selected processes. The central monitoring facility may also use preprogrammed commands to effect reporting at pre-selected times and dates, and may forward pipe/soil potentials or pipeline damage signals to the central monitoring facility.
