Abstract

A monitoring method and a monitoring device for a motor-driven door, wherein a stationary unit and a monitoring device mounted on the movable door communicate bidirectionally with one another, wherein data and/or signals of at least one door safety sensor are relayed to the stationary unit, and wherein a waking device is automatically wakened cyclically or is wakened by a vibration sensor and wakes the control device, which in turn wakes the transmitter/receiver and actively queries the stationary unit assigned individually to it as to whether the monitoring device must remain active or be switched back to a power-saving idle state.
