| 摘要 |
<p>The invention concerns a power supply rail (1) in the form of a profiled section (3), wherein are longitudinally arranged electrically conductive tracks (4), which co-operate with current collector shoes (11) borne by the collector carriage (2), guided by the rail (1), said carriage being connected to a mobile element to be electrically powered. Inside the rail (1) is provided a continuous position and/or displacement detecting track (17), which co-operates with a detector (18) borne by the part (7) of the collector carriage (2) housed inside the rail (1). The detector is linked to signal processing means (23). The instantaneous position and/or the displacement of the associated mobile element can thus be controlled.</p> |
