Train operation control method and system

Abstract

The invention discloses a train operation control method and system. The method comprises steps of building a virtual vehicle-mounted equipment model and a virtual trackside equipment model in groundcontrol equipment; based on the virtual vehicle-mounted equipment model and the virtual trackside equipment model, performing safety logic control on trains within the jurisdiction range of ground control equipment. The method is advantaged in that the virtual vehicle-mounted equipment model and the virtual trackside equipment model are arranged in the ground control equipment, so functions of thevehicle-mounted equipment are simplified, the number of safety equipment of the train operation control system and interfaces between the equipment are greatly reduced, system cost is reduced, and compatibility and safety of the system are improved.

Description

technical field [0001] The invention belongs to the field of rail transit, and in particular relates to a train operation control method and system. Background technique [0002] Existing train operation control methods and systems have the following disadvantages: [0003] 1. The on-board functions of the train in the existing train operation control system are complex. In addition to collecting sensor signals such as speed and position, it is also responsible for speed measurement and distance calculation, train positioning calculation, level mode management and dynamic speed-distance monitoring curve Generation and many other safety application functions. Therefore, the safety level of on-board equipment is high, and it is necessary to adopt a two-out-of-two or three-out-of-two hardware architecture to ensure safety, resulting in large volume and complex structure of the vehicle-mounted equipment, so it is difficult to realize the miniaturization, light weight and minimi...

Problems solved by technology

[0003] 1. The on-board functions of the train in the existing train operation control system are complex. In addition to collecting sensor signals such as speed and position, it is also responsible for speed measurement and distance calculation, train positioning calculation, level mode management and dynamic speed-distance monitoring curve Multiple safety application functions such as generation

Therefore, the safety level of on-board equipment is high, and it is necessary to adopt a two-out-of-two or three-out-of-two hardware architecture to ensure safety, resulting in large volume and complex structure of the vehicle-mounted equipment, so it is difficult to realize the miniaturization, light weight and minimize the safety functions of the vehicle-mounted equipment requirements

[0004] 2. The train control on-board equipment in the existing train operation control system uses an embedded computer to perform safety logic operations, and its computing power is limited. Since the equipment is installed in the mobile body (train), it is subject to various objective conditions such as installation space, vibration, and heat dissipation. , the CPU (Central Processing Unit: central processing unit) used in the train control vehicle equipment has relatively low computing power

In addition, since there is no mandatory unified standard for CBTC, there are also differences in the CBTC of different lines in the same city. If you want to operate cross-lines between these lines, you need to equip multiple sets of CBTC on-board equipment such as CBTC1, CBTC2...CBTCn and so on.

Therefore, in order to achieve cross-standard compatible operation of the existing train operation control system, it is necessary to install multiple sets of on-board equipment
