Monitoring and alarming system and method
First Claim
1. A field device for transmitting a notification signal from a remote facility, the field device comprising:
- a sensor to measure a value of a particular operating parameter at the remote facility;
a memory to store threshold data comprising a target parameter value range, a minimum parameter value, and a maximum parameter value for the particular operating parameter;
a processor comprising modules executable by the processor, the modules comprising;
a storage module to store the value of the particular operating parameter in the memory as measurement data;
an event detection module to compare threshold data to the value of the particular operating parameter to detect an event, the event selected from a group consisting of an alarm event, a transfer event, and a non-event; and
a report module to generate a first notification signal comprising measurement data when the transfer event is detected and to generate a second notification signal comprising an alarm message when the alarm event is detected; and
a communication system to transmit the first notification signal via a first communication network using a first communication protocol or to transmit the second notification signal via a second communication network using a second communication protocol;
wherein the sensor measures a second value of the particular operating parameter after a predetermined time period has elapsed from a time the alarm event was detected, and wherein;
the event detection module is further configured to compare threshold data to the second value to detect the event;
the report module is further configured to generate a third notification signal comprising a second alarm message when the event detection module continues to detect the alarm event; and
the communication system is further configured to transmit the third notification signal via the second communication network using the second communication protocol.

Abstract
A system and method for selectively communicating data from a remote facility to a central computing device via one or more communication networks and/or protocols. Measurement data for a particular operation is collected and stored by a field device at the remote facility. The field device compares the collected measurement data to stored threshold data to detect an alarm event or transfer event. If an alarm event is detected, the RTU transfers an alarm message to a user via a first communication network. If a transfer event is detected, the RTU transfers a transfer message to the user via a different communication network. If a no-event is detected, the field device continues to collect and store measurement data for the particular operation.
