Abstract

A streetlight sensor platform comprising a sensor module which is coupled to a controller section having a lower portion for interfacing with a receptacle of a streetlight and an upper portion for receiving the sensor module. The sensor module is coupled to the controller section without the need for tools allowing easy installation and replacement. The sensor can be utilized for intelligent lighting and event notification such as public safety, emergency vehicle alerts, traffic monitoring, alerts and dynamic lighting applications.

Claims

an interchangeable sensor module; and

a controller section, the controller section comprising;

a lower portion for interfacing with a receptacle positioned on an exterior of a body the streetlight fixture for providing power to the controller section; and

an upper portion for receiving and securing the interchange sensor module thereto,

wherein the controller section is powered by the streetlight fixture and the controller section provides a connector to the interchangeable sensor module to power the interchangeable sensor module,

wherein the controller section interfaces with the interchangeable sensor module and provides data from the interchangeable sensor module to one or more surrounding streetlight controllers or a management system coupled to a mesh network through a wireless network interface.

2. The streetlight sensor platform of claim 1 wherein the sensor module is secured to the controller section by a locking nut screwed by a thread on the upper portion of the controller section.

3. The streetlight sensor platform of claim 1 wherein the sensor module is secured to the controller section by a latch mechanism retaining the sensor module to the controller section.

5. The streetlight sensor platform of claim 1 wherein the connector provides power and data transfer with the sensor module.

6. The streetlight sensor platform of claim 1 wherein the connector is provided by interface pins extending from the base of the interchangeable sensor module which contact a plurality of circular interface on a circular printed circuit board (PCB) in the controller section.

7. The streetlight sensor platform of claim 6 wherein the plurality of circular interface contacts are defined by contact rings provided on a top surface of the PCB board having a connector on the bottom surface of the PCB interfacing to the controller section.

8. The streetlight sensor platform of claim 7 wherein the contact rings increase in diameter from the center of the PCB.

9. The streetlight sensor platform of claim 8 wherein the sensor can be rotated about a center axis of the PCB while maintaining contact with the contact rings.

10. The streetlight sensor platform of claim 1 wherein a wireless power transmitter in the controller section provides power to the interchangeable sensor module.

11. The streetlight sensor platform of claim 10 wherein a wireless communication interface is provided between the controller section and the interchangeable sensor module.
