Abstract: A maintenance system for monitoring a gate device includes the gate device having a gate guide, a gate segment which is movably supported in the gate guide, and a sensor which monitors a gate guiding quality. A method for monitoring the gate device includes the gate device having a gate guide, a gate segment which is movably supported in the gate guide, a sensor which monitors a gate guiding quality arranged at the gate segment, and a maintenance unit. The method includes, when a movement of the gate segment occurs, detecting a vibration value and/or an acceleration value of the gate segment via the sensor, and transmitting the vibration value and/or the acceleration value as maintenance data to the maintenance unit.

Abstract: A servicing and monitoring system for monitoring a gate member which is moved by a drive apparatus. The servicing and monitoring system includes a drive control unit which actuates the drive apparatus, a detection device which detects a gate status of the gate member, a first data connection which connects the drive control unit and the detection device and via which a status signal of the gate member is transmitted from the detection device to the drive control unit, and a data reading device which reads the status signal sent from the detection device to the drive control unit and which outputs an alarm signal depending on the status signal read by the data reading device.

Abstract: A maintenance system for a door arrangement. The door arrangement includes a door member and a drive unit configured to drive the door member. The maintenance system includes a control device comprising a motor control unit configured to control the drive unit and a non-temporary memory configured to store door data, a central maintenance data memory comprising maintenance data for at least one of configuring, monitoring and modifying the control device, a first bidirectional data connection, a second bidirectional data connection, and a mobile maintenance device. The door data is retrievable from the non-temporary memory. The mobile maintenance device is configured to be coupled to the non-temporary memory of the control device via the first bidirectional data connection to maintain the door arrangement, and to be directly or indirectly coupled to the central maintenance memory via the second bidirectional data connection.

Abstract: A magnet-based angular displacement measuring system for measuring a rotational movement of a driveshaft. The magnet-based angular displacement measuring system includes a drive shaft comprising a free end. The free end has a coaxial recess so as to form a hollow shaft section. An exciter unit is rotationally coupled to the free end of the drive shaft. A stationary sensor unit functionally cooperates with the exciter unit to measure the rotational movement of the drive shaft.

Abstract: A device for monitoring a machine movement of a movable constructional element includes a detecting device and a control device. The detection device comprises at least one transmission unit which transmits a signal, and a reception unit which receives the signal. The control device comprises an evaluation unit which evaluates the signal received at the reception unit. The control device allows the machine movement upon a receipt of the signal at the reception unit, and to output a first triggering pulse to stop the machine movement in an absence of the signal at the reception unit. The evaluation unit comprises a first threshold value measuring unit to detect a signal strength of the signal received at the reception unit and which, upon detection that a predetermined threshold value of a signal strength is fallen short of, outputs a second triggering pulse to stop the machine movement.
