A system for monitoring machinery and systems in a process plant using a local monitoring and diagnostic system, the system including a plant database configured to store rule sets including at least one rule expressed as at least one of a physics-based model, a data-driven model, and a empirical model of a plant component and a relational expression of a real-time data output relative to a real-time data input, and a server grade computer configured to receive plant component data from a plant unit control panel, generate virtual sensor outputs using the at least one model associated with the plant component, transmit the plant component data and generated virtual sensor outputs to the plant database for storing and to a data visualization system for generating analytical graphics, determine using the at least one model rule set, an operating or performance condition of the plant component in near real-time. |

1. A local monitoring and diagnostic system for a plant, the system comprising:
a client system comprising a user interface and a browser; a plant database configured to store rule sets, the rule sets comprising at least one rule expressed as at least one of a model of a plant component or system and a relational expression of a real-time data output relative to a real-time data input, the relational expression being specific to a plant asset or group of inter-related assets, the plant database is further configured to receive event data from a condition monitoring system associated with the plant, the condition monitoring system configured to analyze plant equipment data for real-time optimization of equipment and selected processes, condition monitoring, and event diagnostics to generate the event data; and a server grade computer configured to communicatively couple to the client system and the database, the server grade computer further configured to:
receive plant component data from a plant unit control panel communicatively coupled to sensors positioned about the plant component,generate virtual sensor outputs using the at least one of the physics-based model, a data-driven model, and a empirical model and the relational expression associated with the plant component or system,transmit the plant component data and generated virtual sensor outputs to the plant database for storing and to a data visualization system for generating analytical graphics as requested by a user of the client system,determine using the at least one of the physics-based model, the data-driven model, and the empirical model rule set, an operating or performance condition of the plant component or system in near real-time, andoutput a visualization selected by a user representing the selected plant component or system, the visualization comprising graphics illustrating the plant component or system and textual information defining values of received and generated data relating to the selected plant component or system. |
