Monitoring system and method

摘要

System and method for monitoring electrical devices such as luminaires, including ballast and/or battery powered lighting components, for variety of fault conditions from central location utilize monitoring unit that interfaces with host lighting fixture or luminaire to allow status of host to be remotely monitored. Monitoring unit can interface with host in fully galvanically isolated manner using current transformers allowing host lighting fixture to be monitored in the least intrusive manner. Monitoring unit can be seamlessly fitted to new luminaires or existing luminaires. Current transformer interface has minimal effect on host ballast functionality and operation. Monitoring system may include a plurality of monitoring units multi-dropped on a single field bus network or in a power line communication. Power for monitoring unit can be derived from field bus network or power line. Operating parameters and addressing information of monitoring unit may be configured via interface using laptop or PC.

主权项

1. A lighting fixture monitoring unit comprising:
a housing; a sensor configured within said housing in a galvanically isolated communication with at least a portion of a wiring of a lighting fixture, said portion of the wiring disposed outside of the housing; and a microprocessor receiving output information from the sensor and outputting monitoring data indicative of a status of the lighting fixture, wherein said output information received from the sensor is based at least on said galvanically isolated communication with said portion of said wiring disposed outside of the housing.
