PLANT CONTROL SYSTEM

PURPOSE:To raise the reliability of a plant control, by executing a control command inputted to an electronic computer, once in the plant state data base provided in the inside of the computer. CONSTITUTION:As a rule, a control command of an operator is received by a CRT input device 2, and is inputted to an electronic computer 3. The inputted control command is executed simulatively in accordance with a plant state data read out from a simulation data base 4. This result is displayed by a request from the CRT input device, by which the operator is able to decide whether the result is good or not, and in case when it is satisfactory, said simulative control is shifted to an actual plant control, and if there is failure in the result, it is decided to be a control command error, its contents are looked over again and are inputted from the CRT input device 2 once again.
