| 摘要 |
The invention relates to a communication apparatus for automatically setting up a data connection between two intelligent devices ( 10, 20, 30 ). The apparatus comprises a coil ( 13, 23, 33 ) for carrying out a contactless data exchange which is part of a transmission oscillator ( 50 ), a communication element ( 12, 22 ) which is connected to the coil ( 13, 23, 33 ) and the data processing component ( 11, 21 ) of an intelligent device ( 10, 20, 30 ) and emits search signals via the coil ( 13, 23, 33 ) to receive a response from another intelligent device ( 10, 20, 30 ), a measuring device ( 14, 24 ) for monitoring a property of the transmission oscillator ( 50 ), which outputs a control signal when ascertaining a change in the monitored property, and a switching apparatus ( 15, 25 ) which is connected to the measuring device ( 14, 24 ) and the communication element ( 12, 22 ) and which switches on the communication element ( 12, 22 ) when it has received a control signal from the measuring device ( 14, 24 ).
