Abstract:
Basic data storage units are defined as tags that each have a particular data value and represent a single piece of data storage representing a logged data value within a centralized data storage system. Each of the tags have associated properties representing metadata stored for each tag comprising a size of the data for that tag or a source of the data for that tag. Each entry into the centralized data storage system represents the particular data value of each of the tag at an instant in time. All data entries in the centralized data storage system comprise one each of the tags, the particular data value of the each tag, and a timestamp for the each tag.
Abstract:
Performances of components of an industrial system are conditionally monitored as a function of key performance indicator data by defining baseline key performance indicator values for raw data obtained by data sensors from the operation of the components, and diagnostic rules to triggering alarms by comparing baseline key performance indicator values to thresholds. Generated alarms are stored in association with the historic raw diagnostic data, times of acquisition of the historic raw data and times of generation of the alarms. Generated alarms are analyzed as a function of the said stored data and times to identify a correlation between different ones of the key performance indicators that are indicative of a required level of intervention, and the diagnostic rules are revised to initiate reporting of generated alarms pursuant to levels of intervention indicated by said correlations.
Abstract:
A method includes obtaining production and control utilization information for an industrial plant, wherein the information is in an electronic format and collected over time, grouping the information, based on a type of the information, into a plurality of groups, wherein the information in each group is for a same type of information, trending the information in each group over time, aggregating the trended information, evaluating the aggregated information based on predetermined evaluation criteria, and generating an electronic signal indicating the information that satisfied the predetermined evaluation criteria and the information that did not satisfy the predetermined evaluation criteria.
Abstract:
Aspects assure the performance of a hoist system. Some aspects model different shape segments to different portions of braking pressure levels acquired over time during an emergency braking event. A linear shape is modeled to braking pressure values decreasing over a first time interval from initiation of the emergency braking event. A constant shape is modeled to generally constant acquired braking pressure values of a next, second time interval, another linear shape modeled to braking pressure values decreasing over a next, third time interval, and another constant shape is modeled to the braking pressure values acquired over a fourth interval from a time at which the speed value drops to zero, until an exponential shape is modeled to braking pressure values of a subsequent fifth interval. A pressure value defined by the constant shape modeled over the fourth interval determines a permissible braking pressure value for the emergency braking event.
Abstract:
A data package format library is provided to load, create and manipulate data from a plurality of different data formats into a format of a data package object. The data package object is a base object that represents a collection of information comprising time series data, equipment models, events, and relates the application-specific information to the time series data. Accordingly, strongly typed time series information from a data input received in one of the plurality of different data formats via an interface of the data package format library is stored in the data package object format. Time stamp data for each data point in another of the different data formats, and scalar and vector time series information in still another of the different data formats, are each received via respective interfaces of the data package format library and stored into the computer-readable storage medium in the data package object format.
