<p>A system for gathering, transmitting and storing data captured from remote monitored sites positioned in the field is shown in Figure 1. The system has specific applicability to distributed power monitoring and reporting and distributed chemical sensing and reporting. Data from transducers monitoring electrical power parameters or water quality parameters are transmitted to the Internet or Intranet via a communications link. Such data is relayed to secure servers where it is formatted, analyzed, and stored for customer retrieval. If alarm conditions exist that require immediate customer notification, such notifications are sent to a customer via one or more telecommunications means, including: pager, cellular telephone, or email. With respect to the distributed chemical sensing embodiments, the invention preferably utilizes fiber optic chemical sensors that address the problem of biofouling. Using anti-fouling measures, the invention can provide continuous, long-term waterway monitoring. With respect to distributed power monitoring and reporting, the invention preferably utilizes a fiber optic current transducer system to measure magnetic fields in electric power and power electronic applications. Such transducers are based upon rare-earth iron garnet (REIG) crystals that exhibit the Faraday effect when placed in a magnetic field.</p> |
