Abstract

The invention discloses an automatic pulling method and system for a turnout leading to a safety line, which are characterized by firstly monitoring the state of a route sequence related to the turnout leading to the safety line, starting a monitoring and pulling logic after the route sequence is clear, continuously checking whether the turnout meets multiple pulling conditions such as non-positioning, stable clear, no equipment limit, enough interval with the next plan and the like in a preset monitoring period, sending a single operation command for pulling to positioning to an interlocking system when the conditions are fully met, then monitoring the execution result of the command and the final state of the turnout in the preset period in parallel, and generating clear alarm to prompt manual intervention if the command is overtime or the pulling is not successful after the period is finished. The corresponding system adds a safety line turnout service module in the autonomous machine to realize the logic in a decoupling mode with the core module. The invention realizes the automation of the switch resetting operation of the leading-to safety line, reduces the labor intensity and the operation risk rate, and has a perfect abnormality handling mechanism.

Description

Automatic pulling method and system for turnout leading to safety line Technical Field The invention relates to a method and a system thereof, in particular to an automatic pulling method and a system for a turnout leading to a safety line, belonging to the technical field of railway driving scheduling control. Background The turnout is a key device for constructing a railway network and a station, is densely arranged in a throat area in the station, and is used for connecting a departure line, a marshalling line, a cargo line and the like, and the core function is to guide rolling stock to transfer from one track to another track, so that a train can enter different stations and tracks for operation. The turnout is a foundation for realizing the branch control of the railway driving route, providing the running functions of train turning, grouping, meeting, crossing and the like, and is one of the most critical and basic devices in the railway line. The switch controls the driving direction by changing the switch rail position, namely the fixed reverse position of the switch. The positioning of the turnout refers to the position where the turnout is always kept open, usually the path through which the train passes straight, and the reversed position refers to the other opening position which is temporarily switched to according to the requirement, usually the path through which the train passes in a curve. The setting principle of the turnout positioning comprises straight-stock priority, safety guiding and operation standard. In some stations, the principle of switch positioning and setting is mainly considered to be the protection function under the safety guide. In order to prevent trains from entering and exiting the signaling machine, rushing into other occupied lines or rushing out of line terminals, the tail end or the throat area of the railway line is provided with a dead end line, namely a safety line or a refuge line. The switch leading to the safety line is the switch leading to the safety line. The positioning arrangement of the turnout is guided by safety, and the turnout is normally opened to the direction (positioning) leading to the safety line, so that the turnout is guided to the preset safety line when the train or train cannot be safely stopped on the main line due to reasons, and more serious accidents are avoided. The railway transportation organization is mainly embodied with the deep defense safety concept by leading to a safety line turnout, such as a station entrance in a direction of a downhill slope with a large gradient, a complex junction line or a marshalling station and a bifurcation line leading to important facilities or special sections. A centralized train traffic control (CTC) system serves as a train operation command and control system, and an operator centrally controls switches in daily operations to route trains. The CTC system and the turnout form a relation of brain and arm, and automation and intellectualization of driving command are realized through a station computer interlocking system. In daily transportation, the turnout to the safety line needs to be turned to the reverse position at a specific time according to the route sequence generated by the stage plan to open the permission signal, and after the train is driven away, the turnout needs to be restored to the positioning (the direction of the safety line) according to the train fineness rule and the safety regulations. Such frequent switching operations between positioning and repositioning are currently mainly done manually. In the prior art, aiming at the pulling operation of the turnout leading to the safety line, the following technical means are mainly adopted: In the prior art, an operator monitors the state of a warning lamp that a safety line turnout arranged by an interlocking system is not positioned at any time. When the train passes through and goes out of the way, the turnout is in the reversed position, the warning lamp is turned on, and an operator manually and singly operates the turnout to position the turnout at a proper time. The scheme is completely dependent on manual operation, each train plan needs to be repeatedly executed, the workload of operators on a busy line is large, pulling time is completely dependent on manual judgment, attention is easily insufficient only by prompting of a warning lamp, a turnout is not reset in time, and potential safety hazards exist. In the second prior art, on the basis of the first technical scheme, the CTC system monitors the state of the interlocking warning lamp and converts the state of the interlocking warning lamp into more striking words and voice alarm so as to strengthen the prompting effect, but the follow-up turnout pulling operation is still manually executed. Although the scheme improves the dominance degree of the alarm, the underlying logic which depends on manual operation is not changed, and in a dense station of driving, alar
