INTERVAL REGULATION WITH TEMPORARY CHANNEL DIVISION

Abstract

Known automatic cab signaling (continuous automatic cab signaling (CACS), integrated continuous cab signaling (ICCS)) involves integration of a separate signaling channel in the rail line, which is a disadvantage in terms of material and energy costs. Except for the coverage of the numerical code automatic locking cab signaling maintains its inherent weaknesses, in particular the problem of electromagnetic compatibility of transmission / reception path of track circuits in parallel operation of automatic blocking and automatic cab signaling. The objective of this article is to consider options for organization of polling / transmission based on requirements for the response time of the system for interval regulation with time division. With account for requirements for reducing energy consumption in the traffic control it is proposed to use a signal of the rail line control as a signal for automatic cab signaling using temporal division of channel for polling of track circuits and information transmission to the locomotive. Useful signal parameters are determined depending on the polling time of the area (response time of the system). It is shown that during temporary control of the rail line it is necessary to strive to have a selection of chains with approximately equal length, and to comply with a number of conditions.
