Temporary speed restriction method of PMI (Poste de Manoeuvre Informatise) interlocking system under spot type ATP (Automatic Train Protection) module

Abstract

The invention discloses a temporary speed restriction method of a PMI interlocking system under a spot type ATP module. The temporary speed restriction method of the PMI interlocking system under the spot type ATP module comprises the steps that TSR (Temporary Speed Restriction) in all track regions is set; a safety order is sent to a PMI through an ATS (Automatic Train Supervision) to eliminate TSR needing not to be set; an initial signal generator TSR of an authorized backup route of the track region with TSR setting is activated and the initial signal generator shows red lamp; the signal generator TSR is in an inactivated state when the backup route is unlocked or the TSR on the backup route is eliminated. The PMI executes temporary speed restriction on one or a plurality of track areas set by a train automatic monitoring sub-system ATS for a spot type ATP module train under a backup module and interlocks and associates signal generators protecting the temporary speed restriction regions.

Description

technical field [0001] The invention relates to the field of urban rail transit. Background technique [0002] When the train passes through an accident, natural disaster, or line area under construction (tunnel work, etc.), or the track area is closed due to the activation of the emergency stop button on the platform, etc., in order to ensure the safety of the train operation, the train running speed should be lower than the preset Set safe speed value - temporary speed limit value. If the running speed of the train exceeds the temporary speed limit value when passing through the temporary speed limit section, it may endanger the driving safety. property loss. [0003] At present, the signaling system can apply the temporary speed limit to the controlled trains running in the CBTC control area under the communication-based train control CBTC (Communication Based Train Control) mode. In the CBTC mode, the movement authorization unit MAU (Movement Authority Unit) receives ...

Problems solved by technology

But in actual work, it is not flexible to set temporary speed limit signs along the line when there is an emergency temporary speed limit, and if the speed is too fast or the driver is tired, misses or does not find the speed limit sign in front of the speed limit section in time, the train will It is possible to enter the speed limit zone by speeding, which may lead to a driving accident
