Abstract:
A method and device for the transmission of control and/or sensor signals between an electronic control and/or data receiving means and a pneumatic device, which are connected together by means of a pneumatic line of flexible plastic material. For the transmission of the signals using acoustic signals, microwaves or changes in pressure in the gaseous medium in the line the control and/or data receiving means and the pneumatic device are provided with at least one first converter for the conversion of electrical signals into acoustic signals or changes in pressure into electrical signal. Accordingly it is possible for electrical lines, otherwise needed for data transmission, to be dispensed with and data transmission takes place by way of the gaseous medium in the pneumatic line.
