RAILWAY TRAFFIC CONTROL AT SPANS AT CTC Russian patent published in 2015 - IPC B61L27/04 

FIELD: transport.

SUBSTANCE: invention relates to railway transport and can be used in dispatcher control systems. Claimed method comprises the following steps: automatic control by locomotive onboard control system over safe speeds and headway of trains equipped with hardware for control over train integrity and that for ultrasound control over integrity of rails, determination of the train current coordinates by allowance for distance made with their intermittent correction by passive radio tracers installed along the track. Note here that said tracers are used for multiple data rewriting to be performed by the gadget installed at tail car of every train and connected with onboard control device via local channel of digital radio communication. Data is read off by appropriate reader installed and coupled with locomotive onboard control device. Trains running at spans are controlled in compliance with pre-compiled plans and schedules and their electronic cards loaded in locomotive control device electronic memory unit. Note here that safe speed and intervals are controlled and supported by appropriate locomotive software of the train running behind.The latter receives initial data from passive tracer readers on motion parameters of trains ahead. This applies both to normal run of the train in compliance with plan and schedule and emergent or target braking. Or, it receives the initial data on ahead train or on signal of entry and exit lights of approach stations at the distance of stable radio communication. Note here that digital radio channel transceivers should be installed at the train and stations with range not smaller than approach sections and connected with locomotive onboard control device or station traffic control device.

EFFECT: simplified railway traffic control, higher traffic safety.
