Embodiment Construction

[0117] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred examples and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0118] Such as figure 1 As shown, a schematic diagram of the Yizhuang Line of the Beijing Subway is provided. The subway line includes 14 stations, wherein Songjiazhuang Station to Ciqu Station is the upward direction, and Ciqu Station to Songjiazhuang Station is the downward direction. This embodiment considers Songjiazhuang to Ciqu Station. For the uplink direction of Yizhuang Railway Station, the time in this embodiment is the morning peak period from 7:30 to 9:00 in the morning, and an initial stage (7:30am) is set. For ...

Abstract

The invention belongs to the technical field of urban rail transit control, and relates to an event-triggered automatic train adjustment control method. The method obtains train information online in real time, and aims at the situation that the train is disturbed and deviates from the established running schedule or the number of passengers When the deviation is too large, when it is detected that the state deviation of the system satisfies certain conditions, the automatic train adjustment control method described in the present invention is triggered to start, and combined with the existing automatic train driving system, it is guaranteed that the train can run normally under delay, ensuring Efficiency, punctuality and ride comfort of rail transit systems. Compared with the existing train adjustment method based on dynamic programming and MPC method, the present invention can reduce the calculation times of control quantity by about 50%, and save the bandwidth of state information transmission.

Description

technical field [0001] The invention relates to the field of urban rail traffic control. More specifically, it relates to an event-triggered method for automatic train adjustment control. Background technique [0002] Urban rail transit is an important part of the urban public transportation system. It has the characteristics of large transport volume, fast speed, high punctuality rate, small land occupation, and low pollution. The concept of sustainable development. However, with the continuous acceleration of the urbanization process in our country, the number of urban rail transit lines continues to increase, and the number of passengers increases sharply. Especially during the peak passenger flow period, the real-time operation of the train is easily affected by external disturbances and deviates from the expected operation time, resulting in passenger congestion, greatly reducing the operating efficiency of the train, and seriously affecting the comfort and punctualit...
