Abstract
A system for an installation and a method for operating a system, including stationary transceiver modules and a vehicle having a transceiver module, the individual transceiver module having a controllable light source and a light sensor, so that a data transmission is able to be carried out between the vehicle and the stationary modules.
Claims16
A system for an installation, comprising:
- stationary transceiver modules;
- and
- a vehicle having a transceiver module, wherein each transceiver module has a controllable light source and a light sensor, so that a data transmission is able to be carried out between the vehicle and the stationary transceiver modules;
- wherein:
- each module has two polarization foils, with polarization directions that differ,
- a first polarization foil covers a first controllable light source and a first light sensor, and
- a second polarization foil covers a second controllable light source and a second light sensor.
A method for operating a system for an installation that includes stationary transceiver modules and a vehicle having a transceiver module, wherein each transceiver module has a controllable light source and a light sensor, so that a data transmission is able to be carried out between the vehicle and the stationary transceiver modules, the method comprising at least one of:
- transmitting data between the vehicle and one of the stationary transceiver modules using light modulation;
- and
- transmitting a synchronization signal simultaneously from all stationary transceiver modules, for vehicles or stationary machines, each vehicle and machine having a light sensor for detecting the light emitted by one or more controllable light source(s) of the individual module;
- wherein:
- polarized light is transmitted by a stationary transceiver module,
- and an arrangement for ascertaining a polarization direction of the polarized light is situated on the vehicle, the arrangement including a first light sensor, which is situated under a cover of a first polarization foil, and a second light sensor, which is situated under a cover of a second polarization foil, the first and second polarization foils having different polarization directions.
