Method to control in a track traffic system moving units, device for effecting of such control and process for installation of the device
First Claim
1. A method for controlling a plurality of mobile units in a network comprising a central control unit, a plurality of mobile control units each associated with one of said plurality of mobile units, and a plurality of passive position determining members located throughout said network, said method comprising storing data relative to the positions of said plurality of passive position determining members within said network in each of said plurality of mobile control units, scanning said passive position determining members whereby the position of said plurality of mobile units within said network can be determined, sensing the distance traversed by said plurality of mobile units within said network, whereby each of said plurality of mobile control units can continuously determine the momentary position of each of said plurality of mobile units within said network, storing said momentary positions of said plurality of mobile units within said mobile control units, storing data relating to the nature of said network in said central control unit, communicating between said mobile control units and said central control unit for generating control data for controlling each of said plurality of mobile units within said network, said control data being communicated from said central control unit to said plurality of mobile control units including the assignment of a free running distance based upon an allowable minimum distance to a predetermined point in said network, maintaining said free running distance on each of said plurality of mobile units, and forcing the retardation of said mobile units based upon said free running distance being reached.

Abstract
Method and device for control within a line network such as a tram line, of a number of rolling units in various line runnings, and a method for installation of said device. A number of passive position determination elements (9) such as transponders, arranged for radio scanning, are located at determined positions in the network. Control equipment (2) on board said rolling units is provided with devices (8) for scanning of the position determination elements (9) and with sensors (6) for measurement of distance travelled. The momentary unit position within the line network is determined by continuous measurement of distance travelled and by calibration of the thereby obtained position determination by scanning of successively passed position determination elements (9). Data on the design and topography of the line network is stored in a central equipment (1) and communication from the mobile units stating their positions is received in a data processing unit (4). The vehicle control is performed by transmission from the central equipment (1) to each mobile equipment (2) of control data, based on the individual position relative to that of other roling units, said control data comprising allowed minimum distance to the nearest other rolling unit.
