A device for transmitting data includes a transmitter for generating a frequency-modulated output signal. The transmitter includes a phase-locked loop for adjusting an output frequency of the output signal to a carrier frequency, and a coupling circuit for coupling a data stream into the phase-locked loop. The output signal modulated in frequency by the coupled-in data stream has an output frequency variable over time, and the coupling circuit includes a compensation unit, which couples a compensation signal into the phase-locked loop. The compensation signal compensates at least approximately for an adjustment of the output frequency to the carrier frequency carried out by the phase-locked loop.

Device and method for transmitting data

A communication module for a system for transferring data by light beams includes a transmitter for emitting a light beam in which data to be transferred are encoded, and a receiver for receiving a light beam. The transmitter includes a light source, and the receiver includes a light sensor. The transmitter and receiver are disposed offset from each other in a vertical direction. The transmitter emits a light beam in a longitudinal direction. The receiver has a mirror, which can be pivoted about a pivot axis extending in the vertical direction between a folded-out position and a folded-in position. The mirror is disposed such that a light beam incident from the longitudinal direction is deflected toward the light sensor by the mirror in the folded-out position. A system for transferring data by light beams includes at least one first communication module and at least one second communication module.

In a method for operating a technical installation that includes an outer zone, a danger zone, an access zone which provides for access from the outer zone to the danger zone, a light curtain for monitoring the access zone, and at least one mobile system: a protective field is generated and activated in the access zone by the light curtain before entry of the at least one mobile system into the access zone; when the at least one mobile system approaches the access zone, a mobile communication unit of the at least one mobile system transmits a request signal to a stationary communication unit of the light curtain; and after reception of the request signal by the stationary communication unit the protective field is deactivated by the light curtain. A technical apparatus is configured to carry out the method.

In a system and method for operating a system having a rail, a stationary unit, rail-guided mobile parts, and a slotted hollow waveguide, either a first one of the mobile parts or the stationary unit functions as a transmitter, and a second one of the mobile parts functions as a receiver. The transmitter is configured for the simultaneous transmission of an electromagnetic signal and an acoustic signal, e.g., at a first instant. The receiver, which is set apart from the transmitter, is configured to detect the arrival of the electromagnetic signal at a second instant and to detect the arrival of the acoustic signal at a third instant. The second mobile part has an evaluation unit which is configured to determine the distance between the transmitter and the receiver based on the acquired second and third instants.

In a method for a data transmission between first and second modules, and a system having mobile parts for performing the method: the time bases of the first and second modules are synchronized; transmitters of the first module emit a light signal pulse individually one after the other and/or in numbered order in a respective time range; the particular receiver of the second module at which the strongest receive signal occurs is determined, the particular time range and/or the number of the particular time range being determined in which the strongest receive signal occurs; the determined time range and/or the determined number is/are transmitted from the second module to the first module; and the transmitter of the first module associated with the determined time range and/or to the determined number is determined and used for the subsequent data transmission from the first module to the second module.
