Modular monitoring and protection system with distributed voting logic
First Claim
1. A system for monitoring and protection a machine, the system comprising:
- a first sensor for detecting a dynamic operating parameter of the machine at a first location of interest and for generating a first signal representative thereof;
a first monitor coupled to the first sensor for receiving and processing the first signal, the first monitor including a memory for storing voting logic based upon the received signal;
a second sensor for detecting a dynamic operating parameter of the machine at a second location of interest and for generating a second signal representative thereof;
a second monitor coupled to the second sensor and to the first monitor, the second monitor receiving and processing the second signal and including a memory for storing voting logic based upon the received signal, the second monitor being configured to control an operative state of a relay based upon a combination of the voting logic of the first monitor and the voting logic of the second monitor.

Abstract
A system for monitoring and protection machine systems includes multiple monitoring modules positioned proximate to points of interest in the machine system where dynamic operating conditions are monitored. The monitoring modules, which may communicate with one another via an open industrial data exchange protocol, include user-configurable voting logic for controlling or protecting the machine system based upon the monitored conditions. The logic of the modules is interdependent such that certain of the responses will or will not be taken unless combined conditions occur as defined by the voting logic of multiple modules.
