System and related methods for powering and controlling traffic preemption system components |
摘要 |
A traffic preemption system comprising an intersection control module, an intersection preemption unit comprising a signal detector configured to receive a signal transmitted by a vehicle preemption unit mounted to a vehicle and a remotely located electronic device comprising a controller configured to detect a variation in voltage. The system further comprises a cable coupling the intersection controller, the intersection preemption unit, and the remotely located electronic device, the cable comprising a power wire configured to carry a modulated voltage level and share power among the intersection preemption unit and the remotely located electronic device, a ground wire, and a communications wire configured to transmit a communications signal between the intersection preemption unit and the intersection controller. |

1. A traffic preemption system comprising:
an intersection control module; an intersection preemption unit comprising a signal detector configured to receive a signal transmitted by a vehicle preemption unit mounted to a vehicle; a remotely located electronic device to provide a confirmation output of receipt by said intersection preemption unit of said signal transmitted by said vehicle preemption unit, comprising a controller configured to detect a variation in voltage; and a cable coupling the intersection control module, the intersection preemption unit, and the remotely located electronic device, the cable comprising: a power wire configured to carry a modulated voltage level to provide said variation in voltage, and share power among the intersection preemption unit and the remotely located electronic device; a ground wire; and a communications wire configured to transmit a communications signal between the intersection preemption unit and the intersection control module to control traffic light signals according to a preemptive traffic light control procedure responsive to receipt by said intersection preemption unit of said signal transmitted by said vehicle preemption unit.
