Problems solved by technology

[0006] In urban rail transit, there are the following problems in calculating the starting time of the train: if the train starts too late, the train cannot complete the self-inspection and departure process in time, and it will not be able to achieve the task of departure on time at the departure station, causing delays; if the train starts too early Trains, trains can only leave the depot after the main line is idle. If the equipment is idle for too long, it will increase the loss and energy consumption
[0009] 2. The determination of the final value is greatly influenced by human factors, and it is prone to problems of insufficient time or premature start, which requires later adjustment and improvement

Embodiment

[0048] Calculation of the automatic wake-up time of the train of the fully automatic driverless system. figure 2 A schematic diagram of calculating the automatic wake-up time of trains on fully automatic unmanned lines is given. In a fully automatic driving system, the train is usually in a dormant state before it starts. The staff of the control center starts the train located in the garage by remote control. Therefore, the start train is also called the wake-up train. The difference between waking up the train and starting the train on the manned line is that the train-ground communication module is always on and does not need to be started.

[0049] Step 101: Determine the train departure time T based on the timetable 1 and stop time D at the departure station 1 ;

[0050] Train departure time T 1 From the timetable, the departure time of the train and the stop time of the train at the departure station are determined according to the needs of the operation.

Abstract

The invention discloses a train starting time computing method in the field of urban rail transit. The technical scheme is that the method comprises determining train departing time and starting station dwell time, judging the position of a train, setting parameters of a line between the train parking position and a starting station, simultaneously providing a speed-distance curve for train running between the parking position and the starting station, and setting and calculating train parameters related to running; and determining train starting time. The train starting time computing method has a wide application range, can be used for calculation of train automatic-waking time of a full-automatic driving line, and can also be used for calculation of train starting time of an existing urban rail transit line. Based on analysis of the process of train starting to the starting station, interference of human factors is reduced, and estimation precision is improved. Line data and the train parameters can be modified. The train starting time can be calculated according to different lines and trains of different models.

Description

technical field [0001] The invention belongs to the field of urban rail transit, and in particular relates to a method for calculating the starting time of a train. Background technique [0002] In urban rail transit, the trains parked in the depot garage are started every day after a period of time to complete the inspection of the on-board equipment. After confirming that there is no fault, they leave the garage and arrive at the departure station via the switching rail (the demarcation line between the depot and the main line). Operations will then begin as specified in the timetable. This process can be divided into two stages: "on-board equipment power-on self-inspection" and "train departure". [0003] The power-on self-inspection of on-board equipment starts from the driver starting the train in the power-off state, and the train equipment performs self-inspection in a certain order. During the self-test process, some devices or functions can be self-tested at the s...
