Document Type and Number:
WIPO Patent Application WO/2012/105451
Kind Code:
A1
Abstract:
A method for controlling the movement of travelling carriers. Each travelling carrier (1) is provided with data-communication means (13 and 14), which communicate with adjacent travelling carriers (1) in front and behind, and a device-side communication device (15), which communicates with ground-side communication devices. Said ground-side communication devices (18a and 18b) are located at one end of a work segment (WA) and send passage-permission signals to the device-side communication devices (15) on passing travelling carriers (1). This method is characterized by the use of said data-communication means, device-side communication devices, and ground-side communication devices and is further characterized in that the ground-side communication devices (18a and 18b) transmit passage-permission signals, via the device-side communication devices (15) and the data-communication means (13 and 14), to all travelling carriers (1) in the work segment (WA).
