Acquisition and service of temporal data for real-time plant monitoring

Abstract

Data sampled from plants are registered as temporal data, combined with time stamps. We developed a realtime data server which periodically acquires temporal data and transmits them to clients for graphic presentation. The real-time data server consists of multi threads scheduled based on the rate monotonic theory. This paper explains the design of a real-time data server. The prediction for schedulability of it based on the rate monotonic theory has been verified with an experiment on an actual system.

“…This makes them candidates for application of a soft real-time system [9], [10]. In an acquisition system timing requirements are described in terms of sampling period and jitter.…”
