SYSTEM AND METHOD TO DISPLAY DATA DEFINING OPERATION OF A VALVE ASSEMBLY ON A TREND GRAPH ON A USER INTERFACE

摘要

A system and a method to display diagnostic and operating data on a trend graph via a web browser so that the data appears to trend in real-time. In one embodiment, the system includes a server with an architecture having multiple layers. The layers include a pair of first in, first out (FIFO) data queues including a first data queue and a second data queue. The embodiments utilize a timing structure with a plurality of timers including a first timer to regulate calls from the first data queue to a data source (e.g., a valve assembly or controller on a distributed control system), a second timer to regulate calls from the second data queue to the first data queue, and a third timer to regulate calls from the web browser to the second data queue for data to display on trend graph.

主权项

1. A computing device, comprising:
a processor; a memory coupled with the processor; and executable instructions stored on the memory and configured to be executed by the processor, the executable instructions comprising instructions for implementing a system architecture with a plurality of layers and a timing structure that regulates calls for data, the plurality of layers comprising a first layer configured to communicate with a process controller on a distributed control system, a second layer configured to communicate with the first layer, and a third layer configured to communicate with the second layer to form a web server that hosts a web browser for use to display data on a remote terminal via a user interface, wherein the timing structure is configured to regulate data transfer from the process controller to the remote terminal to display the data on a trend graph on the user interface via the web browser.
