Abstract

In an expert system of an operating system e.g. an industrial plant it is desired to input data in the form of relationships between operating parameters of the system to a database. However, if such data are input by inexperienced users, there is the possibility of incorrect data being input. Therefore, a memory stores a plurality of fundamental rules, each being a predetermined relationship between the operating parameters. Then when a datum is input, the fundamental rule(s) corresponding to the operating parameters of the datum are investigated, and the datum is transmitted to the database when each such corresponding fundamental rule is satisfied. In a further development, prevent transmitting datum to a database when each such corresponding fundamental rule is not satisfied.

Claims

1. An operating control system for controlling operation of operation apparatus including a data input system for inputting data to a database having stored therein data which is used by said operating control system to control operation of said operation apparatus, each datum of said data indicating an operating relationship between operating parameters of said operation apparatus, said data input system comprising:

input means for permitting a user to input a new datum of said data to said database to change said control operation performed by said operating control system;

a memory for storing a plurality of fundamental rules, each fundamental rule indicating a predetermined relationship between said operating parameters of said operation apparatus;

processing means for investigating said new datum to determine if fundamental rules corresponding to operating parameters of said new datum are satisfied;

means for transmitting said new datum to said database when each of said fundamental rules corresponding to said operating parameters of said new datum is satisfied to thereby change said control operation performed by said operating control system;

means for preventing transmission of said new datum to said database if any one of said fundamental rules corresponding to said operating parameters of said new datum is not satisfied so as not to change said control operation performed by said operating control system.
