FIELD: construction.
SUBSTANCE: system of door control, providing for its motion from the initial position of its path in the first direction with speed v1 to the final position, the control system comprises a safety function, including a facility to maintain door operation, despite the fact that it collided with an obstacle on its path, and provision of automatic continuation of its initial motion, as soon as the obstacle is cleared, by means of a structure combining quite high normal speed v1 of door motion with solving the task of prevention of door and obstacle damage by reduction of speed up to v3<v1 near the collision saved in the memory.
EFFECT: increased operational reliability.
