Abstract

A roadside warning system is provided for detecting animals alongside a road. The system includes a plurality of infrared heat detection sensors arranged generate a heat signal in response to detection of a body of heat alongside the road. A warning light is illuminated in response to determination by a processor that the body of heat is an animal. A timer keeps the light illuminated for a prescribed period of time following detection of the body of heat in order to warn drivers of animals which have recently passed through the detection zone in addition to warning drivers of animals within the detection zone.

Claims

1. A roadside warning system for detecting animals alongside a road, the system comprising:

a plurality of sensors arranged to be supported alongside the road, each sensor comprising an infrared heat detection sensor arranged generate a heat signal in response to detection of a body of heat alongside the road;

a processor including a prescribed heat condition and being arranged to generate a warning signal representative of an animal in proximity to one of the sensors when the heat signal exceeds the prescribed heat condition; and

a warning light coupled to the processor and being arranged to be activated in response to receipt of the warning signal for warning persons on the road of the presence of the animal.

2. The roadside warning system according to claim 1 wherein the processor includes a timer arranged to latch the warning signal for a prescribed length of time, the warning light being arranged to remain activated until the prescribed length of time has expired.

3. The roadside warning system according to claim 2 wherein the processor and sensors remain active during the prescribed period of time, the timer being arranged to restart upon generation of a second warning signal during the prescribed period of time.

4. The roadside warning system according to claim 1 wherein the heat condition comprises a heat magnitude threshold which must be exceeded in order to generate a warning signal.

5. The roadside warning system according to claim 4 wherein the processor is arranged to automatically adjust the heat magnitude threshold in response to varying ambient temperature.

7. The roadside warning system according to claim 1 wherein there is provided a processor and a warning light associated with each of the sensors.

8. The roadside warning system according to claim 7 wherein each light includes a respective power supply.

9. The roadside warning system according to claim 8 wherein the power supply comprises a battery and a solar panel arranged to recharge the battery.

10. The roadside warning system according to claim 7 wherein each sensor and the processor and warning light associated therewith are all contained within a common housing.

11. The roadside warning system according to claim 10 wherein there is provided a battery within the common housing providing power to the processor and light and a solar panel arranged to recharge the battery, the solar panel comprising a frusto conical shaped member mounted above housing having an upwardly facing apex and being arranged to extend a full 360 degrees of rotation about the housing.

12. The roadside warning system according to claim 11 wherein the housing is insulated.

13. The roadside warning system according to claim 1 wherein each sensor includes a lens having an anti-stick coating thereon.

6. The roadside warning system according to claim I wherein each sensor includes a prescribed field of detection within which a body of heat may be detected, the sensors being mounted along the roadside with the respective fields of detection arranged in an overlapping configuration.
