| 摘要 |
<p>The invention relates to a method and a device for the transmission of control and/or sensor signals between an electronic control and/or data receiving device (21) and a pneumatic device (10), which are connected to one another by a pneumatic line (13) made of flexible synthetic material. The control and/or data receiving device (21) and the pneumatic device (10) are provided with at least one first converter (23) for converting electrical signals into sound signals or changes in pressure in the electrical signals and at least a second converter (24) for converting sound signals or changes in pressure into electrical signals for the purpose of transmitting signals by means of sound signals, microwaves or changes in pressure in the gaseous medium of said line (13). This makes it possible to eliminate electrical lines for data transmission. Data transmission is carried out via the gaseous medium in the pneumatic line (13).</p> |
