Abstract

A coupling device (1) for gas and liquid systems comprises a passive transponder and at least one sensor for measuring at least one quantity. The transponder is connected to the sensor and arranged to wirelessly transmit and receive data via communication protocols. Moreover the sensor is passive, connected to and integrated with the transponder, the sensor being activated with energy induced by the transponder. An independent claim is included for a use of a wireless transmission system in a vehicle.

Claims

1. A coupling device for gas and liquid systems, the coupling device being arranged in an engine compartment of a vehicle, and the coupling device being a quick coupling including a first and a second coupling part, the coupling device comprising:

a passive transponder, the passive transponder being configured to wirelessly transmit and receive data via communication protocols;

at least one passive sensor configured to measure at least one quantity, the at least one passive sensor being connected to the passive transponder, the at least one passive sensor being activated with energy induced by the passive transponder; and

an application specific integrated circuit (ASIC) configured to locally process sensor signals, the ASIC being integrated with the at least one passive sensor and the passive transponder, the ASIC being activated with the energy induced by the passive transponder, and wherein the passive transponder, the at least one passive sensor and the ASIC are arranged in a sealing ring, which sealing ring is arranged spatially between said first and second coupling parts.

2. The coupling device as claimed in claim 1, wherein the sealing ring is a non-conductive material.

3. The coupling device as claimed in claim 1, which is adapted to a high frequency system.

4. A wireless signal transmission system for vehicles, especially engine compartments, which comprises a coupling device as claimed in claim 1 and a reader configured to receive data from the coupling device, wherein the reader is arranged in the engine compartment of the vehicle.

5. The wireless signal transmission system as claimed in claim 4, wherein the reader comprises an antenna, and wherein the reader is arranged at an underside of a bonnet of the engine compartment.

6. The wireless signal transmission system as claimed in claim 4, wherein the reader comprises an antenna and a microprocessor in a unit, which unit is arranged to communicate wirelessly with the coupling device.

7. The wireless signal transmission system as claimed in claim 4, wherein the reader and the coupling device are separated by a distance of at least one of 0.25 meters, 0.5 meters, and 0.75 meters.
