METHOD AND HARDWARE-SOFTWARE SYSTEM FOR TESTING THE CONTROL SYSTEM FOR A MARINE OIL REFINING FACTORY

摘要

1. A method of testing whether the control system (2) is capable of handling errors, failures or failure modes (8) in an oil refinery (1), said control system (2) being configured to! connection to the input signal lines (30) for receiving sensor signals and other input signals (3r) from the said oil refinery (1), and! connecting control signals to lines (40) for transmitting control signals (4) to said oil refinery (1),! providing for the following stages in which:! a) connecting said control system (2) using said input signal line (30) to receive simulated sensor signals and other input signals (3s) from a simulated refinery (10), and! b) connecting said control system (2) using said control signal line (40) for transmitting control signals (4) to said simulated refinery (10),! characterized in that! c) connecting an input signal modifier (9) to said input signal line (30), said input signal modifier (9) modifying one or more of said input signals (3) to transmit one or more modified input signals (13) and the remaining modified input signals (3) to said control system (2). ! 2. The method according to claim 1, in which the modifier (12) of the output or control signals is connected to the said line (40) of the output control signals, the modifier (12) of the output control signals modifies one or more of the mentioned control signals (4) in
