US 7,127,312 B2 · Method and system for acquiring and storing data from a production plant

Abstract

A method and a system acquire and store data from a production plant in order to provide relevant data for a fault analysis. Here, the production plant is allocated a data server, with the aid of which production data acquired by measurement are buffered. By a data input of a data processing device, additional information, which an operator inputs, can be acquired. By an event monitoring functional unit belonging to the data processing device, an evaluation of production data is carried out cyclically, the event monitoring system has access to production data in the data server, as well as to the additional information, on the basis of monitoring criteria which are contained in a stored script, and stores relevant production data in one of a number of databases depending on the event detected.

A method for acquiring and storing data from a production plant to provide relevant data for a fault analysis, which comprises:

assigning the production plant a data server, the data server buffering production data acquired by measurement;
acquiring additional information, input by an operator using a data input of a data processing device;
and
using an event monitoring functional unit of the data processing device for carrying out an evaluation of the production data cyclically, the event monitoring functional unit accessing the production data stored in the data server and the additional information on a basis of monitoring criteria, the monitoring criteria being contained in a stored script, and, depending on an event detected, the event monitoring functional unit directing a storing of relevant production data in one of a number of procedure-dependent databases, the relevant production data being stored in a procedure-dependent database depending on a type of the predefined event;
and
for a detected fault event, storing in a fault event database the designation of the event, the start of the occurrence and the duration of the fault event.
