Abstract

A unit and method for remotely monitoring and/or controlling an apparatus and specifically for remotely monitoring and/or controlling street lamps. The lamp monitoring and control unit comprises a processing and sensing unit for sensing at least one lamp parameter of an associated lamp, and for processing the lamp parameter to monitor and control the associated lamp by outputting monitoring data and control information, and a transmit unit for transmitting the monitoring data, representing the at least one lamp parameter, from the processing and sensing unit. The method for monitoring and controlling a lamp comprises the steps of: sensing at least one lamp parameter of an associated lamp; processing the at least one lamp parameter to produce monitoring data and control information; transmitting the monitoring data; and applying the control information.

Claims

1. A lamp monitoring and control unit, comprising:

a processing and sensing unit configured to acquire and output monitoring data of an associated lamp; and

a transmit unit configured to wirelessly transmit the monitoring data output by the processing and sensing unit without external prompting;

wherein the processing and sensing unit and the transmit unit are located substantially near a top of a lamp pole.

2. The lamp monitoring and control unit of claim 1, further comprising a light sensor, coupled to the processing and sensing unit, for sensing an amount of ambient light, producing a light signal associated with the amount of ambient light, and outputting the light signal to the processing and sensing unit.

3. The lamp monitoring and control unit of claim 2, wherein the light signal from the light sensor is a threshold indication signal.

4. The lamp monitoring and control unit of claim 2, wherein the light sensor comprises a photo sensor and a light sensor circuit.

5. The lamp monitoring and control unit of claim 1, further comprising a standard three prong plug to couple the lamp monitoring and control unit to the associated lamp.

6. The lamp monitoring and control unit of claim 1, wherein the processing and sensing unit receives a hot power line and a neutral power line and outputs a switched power line.

7. The lamp monitoring and control unit of claim 6, wherein the lamp monitoring and control unit is coupled to the associated lamp via a standard three prong plug which carries the hot power line, the switched power line and the neutral power line.

8. The lamp monitoring and control unit of claim 6, wherein the processing and sensing unit comprises a current sensor for sensing a switched current in the switched power line.

9. The lamp monitoring and control unit of claim 1, wherein the associated lamp is a street lamp mounted substantially near a top of the lamp pole.

10. A lamp monitoring and control unit, comprising:

a processing and sensing unit configured to acquire and output monitoring data of an associated lamp; and

a transmit unit configured to wirelessly transmit the monitoring data output by the processing and sensing unit at random times;

wherein the processing and sensing unit and the transmit unit are located substantially near a top of a lamp pole.

11. The lamp monitoring and control unit of claim 10, further comprising a light sensor, coupled to the processing and sensing unit, for sensing an amount of ambient light, producing a light signal associated with the amount of ambient light, and outputting the light signal to the processing and sensing unit.

12. The lamp monitoring and control unit of claim 11, wherein the light signal from the light sensor is a threshold indication signal.

13. The lamp monitoring and control unit of claim 11, wherein the light sensor comprises a photo sensor and a light sensor circuit.

14. The lamp monitoring and control unit of claim 10, further comprising a standard three prong plug to couple the lamp monitoring and control unit to the associated lamp.

15. The lamp monitoring and control unit of claim 10, wherein the processing and sensing unit receives a hot power line and a neutral power line and outputs a switched power line.

16. The lamp monitoring and control unit of claim 15, wherein the lamp monitoring and control unit is coupled to the associated lamp via a standard three prong plug which carries the hot power line, the switched power line and the neutral power line.

17. The lamp monitoring and control unit of claim 15, wherein the processing and sensing unit comprises a current sensor for sensing a switched current in the switched power line.

18. The lamp monitoring and control unit of claim 10, wherein the associated lamp is a street lamp mounted substantially near a top of the lamp pole.

19. The lamp monitoring and control unit of claim 10, wherein the transmitter comprises a modulator and an antenna.
