    摘要: The present invention is capable of realizing normal control of a control device and safe operation of a control target. In the present invention, an automatic control unit 10 generates a control output that is output to a control target in response to an input 1. A safety verification control unit 20 is configured to verify safety of the control output at a plurality of verification levels, and controls the control output on the basis of the verification result. A verification level selection unit manages the state related to the normality of the automatic control unit 10, and selects the verification level of the safety of the control output in the safety verification control unit 20 in accordance with the state.

    摘要: The problem of ensuring safety and work efficiency for the actions of a control target is addressed in an environment in which different types of control systems coexist. A safety control server controls the actions of respective control targets in differing systems and includes an action adjustment unit that, for each control target of differing control systems, outputs to a control target an action adjustment instruction for adjusting the action of that control target when a contention occurs in which the action of that control target deviates from an assumed control result. An action plan adjustment unit, when the adjustment of the action satisfies a prescribed condition, adjusts an action plan indicating an action rule for achieving a function and avoiding a contention in a control target; and a safety rule adjustment unit adjusts a safety rule indicating an action rule for avoiding a contention in the control target.

    摘要: A control system includes: an operation interface generates operation amount information and priority information on the basis of an operation amount; an automatic control unit generates an automatic control output based on a predetermined input; a safety verification unit verifies the safety of the automatic control output; and an output control unit produces a control output in accordance with the automatic control output or the operation amount information on the basis of the automatic control output, the operation amount information, the priority information, and the safety verification result from the safety verification unit. The control output is generated in accordance with the automatic control output, in accordance with the operation amount information only when the control output is verified as safe by the safety verification unit, or in accordance with the operation amount information regardless of whether the control output is verified as safe by the safety verification unit.
