Abstract
A method (and system) is for monitoring a lighting system. Physical location information is received in respect of each lighting unit of the system. Supply voltage information is also received in respect of each lighting unit. Based on the physical location of each lighting unit and the supply voltage information, power network information is derived which identifies cable routes between the lighting units and the locations of lighting cabinets along the cable routes.
Claims15
A method of monitoring a lighting system which comprises a plurality of lighting units positioned along at least a supply cable comprising:
- obtaining physical location information in respect of each lighting unit;
- receiving supply voltage information in respect of each lighting unit;
- and
- based on the physical location of each lighting unit and the supply voltage information, deriving power network information which identifies the cable routes between the lighting units;
- wherein the step of deriving power network information comprises the following steps of:
- clustering the lighting units based on their physical locations;
- identifying the cable routes between the lighting units based on voltage information within each cluster.
A lighting system monitoring arrangement, for monitoring a lighting system which comprises a plurality of lighting units, wherein each lighting unit comprises a supply voltage monitoring system, wherein the monitoring arrangement comprises:
- a receiving module for receiving a physical location of each lighting unit and for receiving supply voltage information from the supply voltage monitoring system;
- and
- a controller which is adapted to derive power network information, from the physical location information and the supply voltage information, which identifies the cable routes between the lighting units;
- and
- wherein the controller is further adapted to:
- cluster the lighting units based on their physical locations;
- identify the cable routes between the lighting units based on voltage information within each cluster.
