Abstract
The present disclosure generally relates to a working machine, including an illumination system adapted for illuminating an area externally of the working machine based on a dynamically determined safety light beam pattern. The present disclosure also relates to a corresponding illumination arrangement, a computer implemented method and a computer program product.
Claims20
A first working machine, comprising:
- a working machine structure,
- a sensor system arranged at the working machine structure and adapted to monitor an environment external of the first working machine,
- an illumination system arranged at the working machine structure and adapted to illuminate an area externally of the first working machine, and
- a control unit connected to the sensor arrangement and the illumination arrangement, wherein the control unit is adapted to:
- determine, based on information received from the sensor system, if an unprotected person is present in a predefined area surrounding the first working machine,
- receive, from a data source external of the first working machine, information indicative of a second working machine in the predefined area surrounding the first working machine, the information further comprising a hazardous area for the second working machine,
- correlate a hazardous area for the first working machine with the hazardous area for the second working machine, forming a correlated hazardous area,
- determine a movement path for the unprotected person outside of the correlated hazardous area,
- form a safety light beam pattern based on the determined movement path, and
- control the illumination system for illuminating the area externally of the first working machine based on the safety light beam pattern.
An illumination arrangement for a work site where at least a first and a second working machine are operating, the illumination arrangement comprising:
- a sensor system,
- an illumination system,
- a server arranged in communication with the sensor system and the illumination system,
- wherein the server is adapted to:
- determine, based on information received from the sensor system, if an unprotected person is present in a predefined area surrounding at least one of the first and the second working machine,
- determine a correlated hazardous area for the first and the second working machine based on a present or predicted operation of the first and the second working machine,
- determine a movement path for the unprotected person outside of the correlated hazardous area,
- form a safety light beam pattern based on the determined movement path, and
- control the illumination system for illuminating an area of the work site based on the safety light beam pattern.
A computer implemented method for controlling an illumination arrangement for a work site where at least a first and a second working machine are operating, comprising the steps of:
- determining, based on information received from a sensor system, if an unprotected person is present in a predefined area surrounding at least one of the first and the second working machine,
- determining a correlated hazardous area for the first and the second working machine based on a present or predicted operation of the first and the second working machine,
- determining a movement path for the unprotected person outside of the correlated hazardous area,
- forming a safety light beam pattern based on the determined movement path, and
- controlling an illumination system comprised with the illumination arrangement for illuminating an area of the work site based on the safety light beam pattern.
A computer program product comprising a non-transitory computer readable medium having stored thereon computer program means for controlling an illumination arrangement for a work site where at least a first and a second working machine are operating, wherein the computer program product comprises:
- code for determining, based on information received from a sensor system, if an unprotected person is present in a predefined area surrounding at least one of the first and the second working machine,
- code for determining a correlated hazardous area for the first and the second working machine based on a present or predicted operation of the first and the second working machine,
- code for determining a movement path for the unprotected person outside of the correlated hazardous area,
- code for forming a safety light beam pattern based on the determined movement path, and
- code for controlling an illumination system comprised with the illumination arrangement for illuminating an area of the work site based on the safety light beam pattern.
