Problems solved by technology

Since the actual operation of the train is very complicated, tracking a single speed value will cause a large deviation between the actual operation and the simulation calculation, and may even fail to reach the prese

Embodiment 1

[0041] figure 1 A schematic diagram of the working principle of a train automatic control system provided by an embodiment of the present invention. During train operation, the ATP system continuously reads line data (slope, curvature, parking position, line speed limit) and detects the distance between the train and the train ahead. The distance between them is used to calculate the braking curve and send it to the ATO system, requiring ATO to control the speed of the train not to exceed the braking curve. In addition, ATO also receives the actual speed of the train and the distance traveled by the train from the ATP, and receives information such as the operation chart data (current time, target time, jump stop operation, detaining the train) and the train operation level from the ATS. ATO sends control and signal instructions to the vehicle according to the received information and the vehicle parameters sent by the vehicle (train load, maneuverability, braking capacity, hi...

Embodiment 2

[0086] Assuming that train A will depart for the next stop, train A will receive the operation data from the travel control center. The operation control center determines the running time of the train between stations A according to the punctuality of the timetable and the traffic volume of the system. The pre-planned inter-station operation levels 2, 3, 4 and their corresponding recommended speed curves are stored in the on-board equipment. Among them, when the operation level two is selected, the train runs completely according to the timetable, which cannot meet the requirements of the control target. Levels 3 and 4 are the operating levels that meet the control objectives, but the operating time is longer. The higher the operation level, the higher the satisfaction of the control objectives and the longer the corresponding operation time. If the train departs earlier than the scheduled time in the timetable, the running time of the train in the interval of arriving at t...

Abstract

The invention provides a method for controlling train operation on the basis of train operation grades. The method includes determining a plurality of operation grades by the aid of ATS (automatic train control) systems according to train operation plans and control targets when trains are operated between stations, generating recommended speed curves by the aid of ATO (automatic train operation) systems and storing the recommended speed curves in vehicular equipment; automatically selecting corresponding inter-station operation grades and the corresponding recommended speed curves by the aid of the ATO systems according to actual early departure time conditions of the trains, controlling train operation by the aid of the curves, determining train tracking recommended curve control strategies, transmitting control instructions to the trains according to train operation real-time information and operating train tracking recommended speed curves. The method has the advantages that the train operation grades, the corresponding recommended speed curves and the train tracking recommended curve control strategies can be automatically selected to transmit control commands to vehicles according to real-time conditions, real-time information feedback of the vehicles can be received, and accordingly the target control requirements can be met on the premise that the train operation punctuality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of train operation control, in particular to a train operation control method based on train operation levels. Background technique [0002] Urban rail transit is an important part of the urban public transportation system. Due to its advantages of large capacity, high speed, high safety and reliability, it has developed rapidly all over the world. The Automatic Train Control System (ATC) is the core equipment for urban rail transit train operation. Its function is to ensure the safety of the train, reduce the interval between trains, improve the operating efficiency, and increase the comfort and reliability of the train operation. The ATC system consists of three subsystems: Automatic Train Supervision (ATS) system, Automatic Train Operation (ATO) system, and Automatic Train Protection (ATP) system. The ATP system is a safety system, which must comply with the fail-safe principle, and mainly realizes funct...
