Description

Switching method and system of train control vehicle-mounted equipment compatible with multiple systems
Technical Field
The invention relates to the technical field of rail transit, in particular to a switching method and a switching system of train control vehicle-mounted equipment compatible with multiple systems.
Background
At present, the mainstream Train Control System of the urban railway is CTCS-2(China Train Control System 2) + ATO under the ATO (automatic Train operation) technical System of the high-speed railway, and the vehicle-mounted equipment thereof generates a speed mode curve to monitor the Train operation according to the driving permission information transmitted by a track circuit and a transponder; meanwhile, according to the operation plan and the line data transmitted by the temporary speed limiting server, automatic driving is realized under the monitoring of the speed mode curve. The mainstream Train control system of the urban rail transit is CBTC (communication Based Train control), and the vehicle-mounted equipment generates a speed mode curve to monitor the Train running according to the driving permission information transmitted by the area controller; and meanwhile, the automatic driving of the train and the automatic adjustment function of the train running in the section are realized according to the command of the ATS, and the train is ensured to run according to the running time specified by the running chart.
In order to realize the four-network integration, the urban railway has the requirement that a main railway, an inter-city railway and an urban rail transit train cross-line to urban railway run in the planning process. The train control system of the main railway and the inter-city railway and the city railway belong to the CTCS system, and have the condition of cross-line operation. However, urban railways and urban rail transit have no cross-line operation condition due to different train control systems.
In consideration of the difference between the CTCS-2+ ATO and the CBTC train control system, in order to realize the cross-line operation of urban railways and urban rail transit, the current mainstream implementation scheme is to make the vehicle-mounted equipment adapt to ground equipment of different train control system systems at the same time. In this context, the train-mounted equipment can be realized by an integrated type and a split type, the integrated type refers to that a set of vehicle-mounted equipment is used for simultaneously realizing the functions of urban railway train-mounted equipment (for short, urban vehicular equipment) and urban rail transit train-mounted equipment (for short, urban rail vehicle-mounted equipment), and the split type refers to that the urban railway train-mounted equipment and the urban rail vehicle-mounted equipment are overlapped to respectively realize the functions of the urban railway train-mounted equipment and the urban rail vehicle-mounted equipment. The split type vehicle-mounted device has the advantages that the core function logics of the two sets of vehicle-mounted devices are independent, the original system is kept, and the coupling risk and the change risk are low.
In the prior art, the 'multi-network fusion scheme research of a state iron CTCS and an urban rail CBTC train control system' centers on the compatibility requirements of the state iron CTCS-2/3 level train control system and the urban rail CBTC train control system, and provides a scheme that vehicle-mounted equipment is suitable for ground equipment of different systems according to respective characteristics. Meanwhile, the method specifically discusses and analyzes key problems of system selection of ground signal equipment of a newly-built line, switching modes of vehicle-mounted equipment under different systems of cross-line positions, vehicle-ground wireless communication modes and the like, but the method has important guiding significance only for engineering design and construction implementation related to signal systems of intercity railways and urban railway, and has no specific implementation scheme and device. Patent CN110920694A and patent CN 106741013B disclose manual and automatic switching functions related to vehicle-mounted devices, but do not disclose starting conditions and switching conditions checked in the switching process, nor do they disclose two switching modes of manual and automatic switching to realize parking and non-parking. Patent CN110920694A discloses manual and automatic switching functions for vehicle-mounted devices, but the starting conditions and switching manner in the switching process are not described in detail.
At present, how to overlap and switch urban area vehicle-mounted equipment and urban rail vehicle-mounted equipment is a split difficulty, and is a key problem for realizing cross-line operation of urban railways and urban rail transit.
