Problems solved by technology

[0005] However, the main goal of the existing automatic train adjustment technology is to adjust the deviation between the actual operation of the train and the timetable, so as to reduce the time of the morning and evening of the train, so that the actual operation of the train is consistent with the planned operation; that is, automatic In the adjustment calculation process, it is only based on the punctual target, and lacks the consideration of the train energy-saving curve

Embodiment 2

[0036] In order to facilitate understanding of the present invention, below in conjunction with Figure 2-3 Further introduction to punctual and energy-saving adjustment strategies.

[0037] (1) The purpose of the punctual adjustment strategy is to make the train operation that deviates from the timetable return to the state consistent with the timetable as quickly as possible through the adjustment of the train; it specifically includes two steps: 1) Calculating the train stop time ; 2) Predict whether the train is late based on the train stop time, and make a preliminary selection of the operating curve.

[0038] The following adjusts the strategy according to time and combines figure 2 , to give a detailed description of the calculation process of the train stop time.

[0039] like figure 2 As shown, it represents a time-distance map of a train from station A to station C via station B, the abscissa is time, and the ordinate is the station. figure 2 Among them, T1 in...

Embodiment 3

[0073] Figure 4 It is a schematic diagram of a punctual and energy-saving train automatic adjustment system provided by Embodiment 3 of the present invention. like Figure 4 As shown, the system mainly includes:

[0074] Train stop time and section operation level calculation module 41, used to judge whether the number of online trains in the current train section exceeds the threshold value; if it exceeds the threshold value, then calculate the train stop time and section operation level according to the punctual adjustment strategy ; If the threshold value is not exceeded, calculate the train stop time and section operation level according to the energy-saving adjustment strategy.

[0075] The system also includes:

[0076] The online train number acquisition module 42 is used to obtain the online train number in the current train section; specifically: according to the received light band information sent by the interlocking system and the train position information sen...

Abstract

The invention discloses an on-time and energy-saving train automatic adjusting method and an on-time and energy-saving train automatic adjusting system. The method comprises the following steps of judging whether the number of on-line trains in a current railway section exceeds a threshold value or not; if the number exceeds the threshold value, performing calculation according to an on-time adjusting strategy so as to obtain a train stop time and a region running level; if the number does not exceed the threshold value, performing the calculation according to an energy-saving adjusting strategy so as to obtain the train stop time and the region running level. By using the method and system disclosed by the invention, the punctuality and energy-saving ability of running of the train are ensured, and the working amount of dispatchers is reduced.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a punctual and energy-saving train automatic adjustment method and system. Background technique [0002] Automatic train adjustment is an important function in the urban rail transit ATS (Automatic Train Supervision, automatic train monitoring system) system. It calculates the stop of the train at the station by comparing the actual time of the train entering and leaving the station with the original planned time. time, and the operating time or class of the train in the section. The ATS system outputs the adjustment results to the departure indicator on the platform and the on-board control equipment, so as to achieve the purpose of controlling the train operation behavior and order and reducing the workload of the dispatcher. [0003] With the development of train and on-board control technology, urban rail transit trains and related control systems that cooperate w...
