Train onboard control system and train

Abstract

The invention discloses a train and an onboard control system thereof. The system comprises an onboard controller, the onboard controller comprises a logic operation unit, a first IO interface unit and a second IO interface unit, the logic operation unit and the first IO interface unit are both disposed at one end of the train, the second IO interface unit is disposed at the other end of the train, and the logic operation unit is connected with the first IO interface unit and the second IO interface unit through an industrial field bus respectively; the logic operation unit is used for controlling the train to execute controlling commands corresponding to control signals according to the control signals at least including key activation signals of the train collected by the first IO interface unit or the second IO interface unit, and the logic operation unit is used for determining the running direction of the train based on the key activation signals. The system can achieve a bidirectional automatic driving function, reduces a set of logic operation units in configuration, and has low cost and high competitiveness.

Description

technical field [0001] The invention relates to the technical field of train control, in particular to a train vehicle control system and a train. Background technique [0002] As the core system of train safety control, VOBC (Vehicle Onboard Controller) conducts wireless communication between trains and ground through high-speed wireless networks, realizes continuous monitoring of trains, and obtains the best driving interval; through independent positioning of trains, based on The speed-distance curve provides overspeed protection for the train, effectively shortens the tracking distance on the premise of ensuring the safety of the train; realizes the ATO (Automatic Train Operation, automatic train control) function, and automatically controls the start, cruise, precise parking of the train and the connection between the car door and the screen door Linkage to meet the operation requirements of high efficiency, energy saving and comfort. At present, the VOBC of mainstream...

Problems solved by technology

[0004] In the above technology, one set of vehicle-mounted VOBC control systems is placed at the front and rear of the train. When the train is running, only one set is in working state and the other set is in dormant state. The utilization rate is low, and all devices are redundantly configured, and the system cost high
