<p>A device for monitoring the operation of a driving arrangement comprising at least a servo-mechanism (3), which includes a regulator (3a), a driving motor (5) controlled by this regulator and an element (6) which can be set in motion by the driving motor, a detection arrangement (19-22, 23) for detecting deviations between intended and actual movement positions of the element (6) and an operation inhibiting and/or alarming arrangement (23, 36, 37, 38) for inhibiting the operation of the driving arrangement and/or starting an alarm when impermissible deviations have been established by means of the detection arrangement. The device comprises a redundant driving arrangement, which comprises at least one auxiliary servomechanism (4) including a redundant regulator (4a), a redundant driving motor (7) controlled by this regulator and a redundant element (8) which can be set in motion by this driving motor, that the regulator (3a) and the redundant regulator (4a) are connected to an arrangement (2) delivering control information o or imparting to the element and the redundant element movements being the same or having a predetermined relation to each other, and that the detection arrangement is arranged to detect the deviations concerning the relative position or movements of the element (6), or an object (17) connected thereto, and the redundant element (8).</p> |
