Abstract
A remote tracking and sensing device (20) includes a global positioning system receiver (22). A processor (24) receives a position signal from the global positioning system receiver (22). A communication interface (30) connects the processor (24) to at least two wireless communication systems (26, 28). A power management system (32) provides power to the processor (24) based on an output (38) from a motion sensor (40).
Claims22
A remote tracking and sensing device, comprising:
- a global positioning system receiver;
- a processor receiving a position signal from the global positioning system receiver;
- a communication interface connecting the processor to at least two wireless communication systems, the at least two wireless communication systems designed to transmit the position signal;
- and
- a power management system providing power to the processor based on an output from a motion sensor.
A method of operating a remote tracking and sensing system, comprising the steps of:
- (a) attaching the remote tracking and sensing system to a device;
- (b) determining a boundary when a device is turned off;
- (c) when a motion sensor indicates that the device is moving, determining a position of the device;
- and
- (d) when the device is outside of the boundary, sending a position message over a wireless communication system.
A tracking and traffic control system, comprising:
- a global positioning system receiver;
- a processor receiving a position signal from the global positioning system receiver, the processor determining a block based on the position signal and a vehicle information, wherein the position signal is sent periodically and the block is updated each time the position signal is determined;
- a communication interface linking the processor to a communication system;
- and
- a central control system receiving the block over the communication system.
A method of operating a tracking and traffic control system, comprising the steps of:
- (a) attaching a position sensing system to a vehicle;
- (b) determining a position of the vehicle periodically;
- (c) transmitting the position, at regular time intervals, to a central traffic control system;
- (d) calculating a vehicle block based on the position information;
- and
- (e) communicating a traffic control information from the central traffic control system to the vehicle.
