In-pavement wireless vibration sensor nodes, networks and systems

摘要

Apparatus and methods are disclosed that may be configured to respond to vibrations in a pavement induced by the travel of a vehicle on the pavement. The apparatus may include vibration sensor nodes embedded in the pavement and systems using the response of the sensor nodes to generate vehicle parameters, weight estimates, pavement deflection estimates and vehicle classifications. From these and other data, traffic ticket, tariff and insurance messages about the vehicle may be generated. Processors and processor-units are disclosed. Delivery mechanisms to configure the processor units and entities controlling and/or benefiting from the deliveries are disclosed.

1. An apparatus, comprising at least one of
a first processor configured to respond to said vibration readings created by at least one vibration sensor configured to respond to vibrations in pavement induced by travel of a vehicle to generate said vibration report; a second processor configured to respond to said vibration report to generate at least one vehicle parameter of said vehicle; wherein said vehicle parameter includes at least one of a length estimate, an axle count estimate, an axle position estimate vector, an axle spacing vector and an axle width estimate; a third processor configured to respond to said vehicle parameter of said vehicle from said second processor to generate a vehicle classification of said vehicle; a fourth processor configured to respond to said vibration report from said first processor to generate a weight estimate of said vehicle and/or a deflection estimate of said vehicle deflecting said pavement; a fifth processor configured to respond to said vehicle classification from said third processor, a vehicle identification, a vehicle movement estimate and at least one of said weight estimate and said deflection estimate from said fourth processor to generate a vehicle travel record for said vehicle; and a sixth processor configured to respond to said vehicle travel record from said fifth processor to generate at least one of a traffic ticket message, a tariff message and an insurance message, each for said vehicle.
