The device has a hand rail (5) provided with hand rail elements (5.1). A sensor (10) detects a surface of the hand rail. A switching circuit processes sensor signals imaging the surface. The hand rail is segmented or non-segmented. The sensor is an antenna i.e. Wireless local area network (WLAN)antenna, operating in a radio frequency range. The hand rail elements are movable in a near filed of the antenna. A distance of the antenna to the hand rail is approximately 1.5 mm to 3.5 mm. The antenna is designed for 2.4 gigahertz. An independent claim is also included for a method for monitoring a transport device. |
