Computer management control system

摘要

A computer management manufacturing monitoring system for monitors the operation of a manufacturing process. The input section of the system is coupled to a plurality of sensors for monitoring the states of such sensors. A logging program periodically reads the states of various sensors and stores information relating to each such sensor state in a data base. The stored data includes both direct sensor readings and as derived sensor information calculated from readings of the states of certain sensors. The operation of the logging program is predicated on a logging model constructed by an operator. A database storage section stores the information received from the logging program relating to the reading of each sensor state read in a database format. A display generator causes information to be displayed from the database on a display screen. A control program controls the operation of the logging program for determining which of the sensors should be read, when such sensor should be read and whether the readings from each sensor read should be stored as a direct value or used for calculating a derived value that should be stored in the database.
