Antiskid control unit and data collection system for vehicle braking system
First Claim
1. A system for collecting information related to the operation of a wheel on an axle of a moving vehicle, said system comprising:
- a processor associated with the axle;
a wheel speed transducer adapted to provide wheel speed data to the processor;
a data concentrator for storing wheel speed data over a period of time; and
means for downloading the operation information including the wheel speed data from the data concentrator.

Abstract
A wheel speed transducer including a magnetic device associated with a wheel and a sensor device associated with the axle of the wheel provides data indicative of the velocity of the wheel. A processor located at the axle receives the wheel speed data and processes it to perform antiskid control functions. The velocity data is stored in a data concentrator also associated with the axle. A tire pressure sensor, a brake temperature sensor and a brake torque sensor, each associated with the wheel, send data to the processor at the axle, for storage in the data concentrator. A transmitting antenna associated with the axle and in communication with the data concentrator transmits stored data to a receiving antenna associated with the wheel. A data port at the wheel and in communication with the receiving antenna provides an interface to an external device for receiving the data.
