Problems solved by technology

However, at present, my country's railway system is mainly based on the CTCS-2 train control system, and the vehicle-ground communication mainly relies on ground transponders and ground electronic units, which cannot realize real-time wireless communication, so it cannot be applied to CTCS-2 train control systems. in the system

Embodiment

[0075] Such as figure 1 , A train operation speed planning and control system, including ground equipment 110 near the train, and on-board equipment 120 installed on the train. The ground equipment 120 is used to provide the vehicle-mounted equipment 110 with line information including at least the slope of the line, the speed limit information of the front line, and the train occupancy of the front line; the vehicle-mounted equipment 120 is used to receive the line information provided by the ground equipment, and Plan and control the train speed.

[0076] The on-board equipment 120 further includes: a speedometer 121, a human-machine interface 122, a ground equipment response unit, an automatic train protection unit (ATP) 125, a speed control unit 126, and a traction / brake unit 127, of which:

[0077] The speedometer 121 is used to detect the actual running speed of the train and transmit it to the speed control unit 126 through the automatic train protection unit 125.

[0078] T...

Abstract

The invention discloses a system for planning and controlling train travelling speed. The system comprises ground equipment which is approached during travelling of a train, and vehicle-carried equipment arranged on the train. The vehicle-carried equipment comprises a speed meter, a human-computer interface, a ground equipment answering unit, a train automatic protecting unit, a speed control unit and a traction / brake unit, wherein the train automatic protecting unit is respectively connected with the speed meter, the human-computer interface, the ground equipment answering unit and the speed control unit; the ground equipment answering unit is respectively connected with the ground equipment and the train automatic protecting unit; and the speed control unit is respectively connected with the train automatic protecting unit and the traction / brake unit. The system receives information including railway condition, line limit speed, travelling authority and the like, through a ground answerer; the comfort of passengers, the time accuracy and the energy conservation of train travelling are considered at the same time to plan the optimal distance-speed-based target speed running curve; and real-time tracking on the target speed is realized by outputting a proper traction / brake instruction.

Description

Technical field [0001] The invention relates to the technical field of automatic operation of rail transit, in particular to a method and system for planning and controlling train operation speed. Background technique [0002] The national "medium and long-term railway planning" has brought intercity railways into a new development period and a new round of construction climax, and major cities are carrying out rail transit construction. With the development of high-speed railways in our country, the speed of trains and the density of transportation continue to increase, and the operating range continues to increase. Traditional manual driving methods can no longer meet the driving requirements. [0003] In this context, the development of efficient train automatic driving systems is particularly important. The automatic train driving system uses advanced computer technology to perform simulation calculations and predictive simulations of the running process, so as to obtain a rea...
