Abstract

A system to identify incidents associated with streetlight fixtures based on sensor data from one or more smart sensor devices. Each smart sensor device is coupled to a respective streetlight fixture and captures data from one or more sensors. The data from a single smart sensor device or a plurality of smart sensor devices is aggregated to generate a current data signature of the one or more smart sensor devices. The current data signature is compared to a plurality of known signatures to determine if an incident associated with a streetlight fixture has occurred. Such incidents can include a failed light source, a failing light source, a weather incident, a geologic incident, etc. Depending on the type of incident an instruction is sent to the one or more smart sensor devices to perform one or more responsive actions.

a memory arranged to store the received data; and

a computing device that includes:
a memory arranged to store data received from the plurality of smart sensor devices; and
a processor arranged to execute computer instructions that cause the processor to:
aggregate the stored data from the plurality of smart sensor devices;
generate a current data signature from the aggregated data;
compare the current data signature to a plurality of known signatures;
identify an incident affecting at least one of the plurality of streetlight fixtures based on the comparison between the current data signature and the plurality of known signatures;
determine that the identified incident is a failing light source in a first streetlight fixture of the plurality of streetlight fixtures;
identify a first smart sensor device of the plurality of smart sensor devices, the first smart sensor device being coupled to the first streetlight fixture;
identify a second smart sensor device of the plurality of smart sensor devices, the second smart sensor device being coupled to a second streetlight fixture of the plurality of streetlight fixtures and being near the first smart sensor device, the second streetlight fixture including a working light source;
instruct the first smart sensor device to reduce an amount of time in which the failing light source is illuminated at night; and
instruct the second smart sensor device to increase an intensity of the working light source during a time when the failing light source is not illuminated at night.

2. The system of claim 1 , wherein instruction of the first smart sensor device to reduce the amount of time in which the failing light source is illuminated at night includes actions to decrease a threshold amount of light to be detected to illuminate the failing light source.
