Abstract
Facility marking modules (FMM) and methods and systems of using the same. A FMM is associated with a point of interest (POI) at a worksite or other facility. The FMM detects a low frequency magnetic field of a vehicle moving within the facility at or near the POI and transmits a response signal to a proximity detection system (PDS) of the vehicle. The response signal can cause an operational alert lo activate, or to slow, stop, or change direction of the vehicle based on traffic restrictions associated with the POI. In some examples, the response signal can be used to generate vehicular traffic data for improving efficiency and/or safety of the facility.
Claims27
A point of interest (POI) vehicular control system, comprising:
- a fixed-position facility marker module (FMM) associated with the POI and mounted to a fixed structure at or near the POI, the FMM including:
- a processor;
- a tuned circuit configured to receive low magnetic frequency fields, the tuned circuit including a capacitor and an inductor;
- a UHF transceiver;
- and
- an antenna;
- wherein the FMM is configured to transmit a signal using the processor, the UHF transceiver and the antenna only in response to receiving, by the tuned circuit, a pulse of a low frequency magnetic field.
14-16. (canceled)
A facility marker module (FMM), comprising:
- a housing, supporting:
- a processor;
- a tuned circuit configured to receive low magnetic frequency fields, the tuned circuit including a capacitor and an inductor;
- a UHF transceiver;
- and
- an antenna;
- wherein the FMM is configured to transmit signals using the processor, the UHF transceiver and the antenna only in response to receiving, by the tuned circuit, a pulse of a low frequency magnetic field;
- and
- wherein the housing is configured to be mounted to a structure associated with a point of interest of a facility.
25-29. (canceled)
A facility marker module (FMM), comprising:
- a housing, supporting:
- a processor;
- a tuned circuit configured to receive low magnetic frequency fields, the tuned circuit including a capacitor and an inductor;
- a UHF transceiver;
- and
- an antenna;
- wherein the housing is configured to be mounted to a structure associated with a point of interest of a facility;
- and
- wherein the FMM is configured to transmit a signal using the processor, the UHF transceiver and the antenna in response to receiving, by the tuned circuit, a pulse of a low frequency magnetic field, the signal including information about the structure.
