Method for communication between two utility vehicles
A method of communicating information via optical data transmission between two utility vehicles includes providing a control unit on a first utility vehicle, a work light on the first utility vehicle, and a second utility vehicle. The method also includes generating activation signals by the control unit of the first utility vehicle in dependence on transmission data to be transmitted, activating the work light by the activation signals, and emitting light signals via the activated work light to the second utility vehicle. The light signals represent the transmission data.
1. A method of communicating information via optical data transmission between two utility vehicles, comprising:
providing a control unit on a first utility vehicle, a work light on the first utility vehicle, and a second utility vehicle;
generating activation signals by the control unit of the first utility vehicle in dependence on transmission data to be transmitted, wherein the transmission data identifies a location and a technical status of the first utility vehicle which is provided at the first utility vehicle;
activating the work light of the first utility vehicle by the activation signals to change its light intensity in dependence on transmission data transmitted by the second utility vehicle, wherein the transmission data emitted by the second utility vehicle is provided at the second utility vehicle and represents a location and a technical status of the second utility vehicle; and
emitting light signals via the activated work light to the second utility vehicle, where the light signals represent the transmission data of the second utility vehicle.
2. The method of claim 1 , wherein the first utility vehicle comprises an optical receive unit for receiving other light signals from a work light on the second utility vehicle.
3. The method of claim 2 , wherein the optical receiving unit comprises a photodetector.
4. The method of claim 2 , further comprising converting the other light signals from the second utility vehicle and received by the optical receiving unit into transmission data.
5. The method of claim 1 , wherein transmission data emitted by the first utility vehicle represents a technical status or location of the first utility vehicle.
6. An arrangement for communication between a first and a second utility vehicle by optical data transmission, comprising:
a control unit located on the first utility vehicle for generating activation signals in dependence on data to be transmitted, wherein the data to be transmitted is first utility vehicle transmission data that identifies a location and a technical status of the first utility vehicle received through a first utility vehicle CAN bus; and
a work light located on the first vehicle activatable by the activation signals of the control unit to emit light signals representative of the first utility vehicle transmission data and in response to second utility vehicle transmission data that identifies a location and a technical status of the second utility vehicle.
7. The arrangement of claim 6 , wherein the work light comprises at least one LED.
8. The arrangement of claim 6 , wherein the second utility vehicle comprises an optical receive unit for receiving light signals transmitted by the work light located on the first utility vehicle.
9. The arrangement of claim 8 , wherein the optical receiving unit comprises a photodetector.
10. The arrangement of claim 6 , further comprising a signal converter for converting the light signals from the first utility vehicle into the first utility vehicle transmission data.
11. The arrangement of claim 6 , further comprising:
a second control unit located on the second utility vehicles for generating activation signals in dependence on data to be transmitted, wherein the data to be transmitted is the second utility vehicle transmission data received through a second utility vehicle CAN bus; and
a second work light located on the second vehicle activatable by the activation signals of the second control unit to emit light signals representative of the second utility vehicle transmission data.
12. The arrangement of claim 11 , wherein the second work light comprises at least one LED.
13. The arrangement of claim 11 , wherein the first utility vehicle comprises an optical receive unit for receiving light signals from the second utility vehicle.
14. The arrangement of claim 13 , wherein the optical receiving unit comprises a photodetector.
15. The arrangement of claim 11 , further comprising a signal converter for converting the light signals from the second utility vehicle into second utility vehicle transmission data.
16. A utility vehicle, comprising:
a control unit for generating activation signals in dependence on data to be transmitted via optical data transmission, wherein the data to be transmitted is utility vehicle transmission data received through the utility vehicle CAN bus; and
a work light activatable by the activation signals of the control unit to emit light signals representative of the utility vehicle transmission data; and
an optical receive unit for receiving light signals from another utility vehicle, wherein the received light signals are based on another utility vehicle transmission data received through the another utility vehicle CAN bus.
17. The utility vehicle of claim 16 , wherein:
the work light comprises at least one LED;
the optical receive unit comprises a photodetector; and
a signal converter for converting the light signals from the another utility vehicle into a light intensity of the work light based on a position of the another utility vehicle.
