Wireless connection of sensors to outdoor lighting system
Provided is a sensor system for an outdoor lighting system including at least one sensor physically connected with an external connector of a lighting fixture of the outdoor lighting system. The sensor performs sensing and wireless data and power connection, via a wireless power source and a wireless data source, with the outdoor lighting system.
1. A sensor system for an outdoor lighting system comprising a lighting fixture and an external connector disposed on the lighting fixture, the sensor system comprising:
at least one sensor physically connected with the external connector and configured to perform (i) sensing, and (ii) wireless data and power connection, via a wireless power source and a wireless data source, with the outdoor lighting system;
wherein the outdoor lighting system further includes a node for controlling power to the outdoor lighting system, and
wherein the sensor system is disposed between the node and the external connector.
2. The sensor system of claim 1 , further comprising:
a power interface configured to receive power from the outdoor lighting system via the wireless power source;
a data interface configured to receive data from the outdoor lighting system via the wireless data source.
3. The sensor system of claim 2 , further comprising a processing unit configured to:
(i) perform wireless communication with a processing unit of a lighting driver of the outdoor lighting system, using a processing unit of the node,
(ii) control the at least one sensor, and
(iii) perform fault management and status reporting of the at least one sensor.
4. The sensor system of claim 3 , wherein the power interface is further configured to wirelessly connect the sensor system to a power supply of the node.
5. The sensor system of claim 3 , further comprising:
an energy harvesting interface configured to harvest energy from an external energy source; and
an energy storage configured to receive the harvested energy from the energy harvesting interface and store the energy for use by the sensor system.
6. The sensor system of claim 3 , wherein the processing unit is further configured to communicate with an external system for obtaining sensing data to monitor and control the outdoor lighting system, wherein the processing unit of the node is configured to receive at least one command signal from the external system, and transmit the sensing data in response to the at least one command signal received.
7. The sensor system of claim 6 , wherein the processing unit is further configured to send at least one control signal to the processing unit of the lighting driver to control the power and data of the outdoor lighting system.
8. The sensor system of claim 1 , wherein the wireless power source and the wireless data source is an RF source.
9. A sensor system for an outdoor lighting system including a lighting fixture, the sensor system comprising:
at least one sensor;
a wireless source connector connected to the lighting fixture, wherein the at least one sensor is configured to: (i) perform sensing, and (ii) perform wireless data and power connection, via the wireless source connector, with the outdoor lighting system; and
a processing unit configured to: (i) perform wireless communication with a processing unit of a lighting driver of the outdoor lighting system, (ii) control the at least one sensor, and (iii) perform fault management and status reporting of the at least one sensor.
10. The sensor system of claim 9 , further comprising:
an energy harvesting interface configured to harvest energy from an external energy source; and
an energy storage configured to receive the harvested energy from the energy harvesting interface and store the energy for use by the sensor system.
11. The sensor system of claim 9 , wherein the processing unit is further configured to communicate with an external system, for obtaining sensing data to monitor and control the outdoor lighting system, and wherein the processing unit of the sensor system is configured to receive at least one command signal from the external system, and transmit the sensing data in response to the at least one command signal received.
12. The sensor system of claim 11 , wherein the processing unit is further configured to send at least one control signal to the processing unit of the lighting driver to control the power and data of the outdoor lighting system.
