Optical master unit alarm collector and translator
First Claim
1. A computer-implemented system, comprising:
- a remote terminal unit (RTU) configured to receive alarm information and communicate alarm event information to a control center;
an optical master unit (OMU) configured to receive alarm information from sensors at remote locations; and
a circuit board configured to serve as a middle device between the RTU and the OMU and comprising;
a microcontroller that communicates with the OMU and processes replies from the OMU to confirm the existence of and identify the type of an alarm at a particular remote location;
multiple output relays connected to the RTU and corresponding to remote alarms, each output relay associated with a particular sensor at a remote location; and
an input relay for communicating with the OMU.

Abstract
A computer-implemented system includes the following. A remote terminal unit (RTU) is configured to receive alarm information and communicate alarm event information to a control center. An optical master unit (OMU) is configured to receive alarm information from sensors at remote locations. A circuit board is configured to serve as a middle device between the RTU and the OMU. A circuit board includes a microcontroller that communicates with the OMU and processes replies from the OMU to confirm the existence of and identify the type of an alarm at a particular remote location. The circuit board also includes multiple output relays connected to the RTU and corresponding to remote alarms, each output relay associated with a particular sensor at a remote location. The computer-implemented system also includes an input relay for communicating with the OMU.
