Abstract
According to the invention a rail vehicle wheel sensor assembly (ZCK) is provided that comprises a rail vehicle wheel detection system (UWK) and a two-wire interface in the form of a current loop, by means of which the wheel detection system (UWK) is connected to an external device (SO). The wheel sensor assembly (ZCK) is characterised in that it comprises a wheel detection configuration system (UKDK) connected to the wheel detection system (UWK), an authorisation and configuration system (UA) capable of storing at least one secret (SK), used for secure communication with the external device (SO) and for forwarding configuration commands to the wheel detection configuration system (UKDK) connected thereto, a communication converter system (UM) used for the signal conversion, a wheel sensor supply voltage conversion system (UKU), a voltage summation and voltage-to-sensor-output-current conversion system (UKUI), an output signal permission system (UZSW) and a power supply system (UZ).
