FIELD: physics; control.SUBSTANCE: invention relates to railway automation and telemechanics. The system for interval control of movement of mobile units of rail transport on a railway haul comprises traffic lights, track circuits of protective sections of intermediate traffic lights and a block section. For each block section there is a unit for controlling track circuits, a controller, a code signal transmitting unit, a unit for turning on coding and a signal indication unit, connected to an intermediate traffic light. There is also a code signal transmitting unit and a unit for turning on coding. Each block section is fitted with a short-range digital radio communication transceiver, which is connected through an interfacing unit to the controller, which is connected to the unit for controlling track circuits and to the software-hardware of an automated workstation. The control centre is fitted with a long-range digital radio communication transceiver, and the mobile unit is fitted with on-board short-range and long-rage digital radio communication transceivers which are connected to the on-board device for controlling the mobile unit.EFFECT: high reliability of the system.3 cl, 1 dwg |
