Problems solved by technology

[0004] If the axle load is too large, the load-carrying requirements of infrastructure such as bridges, culverts, and roadbeds are high, and a large amount of investment is required for reinforcement, and the renovation period is long, which will affect normal transportation operations; Expansion and reconstruction will increase the land area; the marshalling and unmarshalling of heavy-duty combined trains will occupy station resources for a long time, and small stations will also occupy the throat area or even the interval, seriously affecting on-site transportation operations
The length and weight of the train increase, which makes it difficult to solve the problem of longitudinal force in the operation of the train, which is likely to cause off-line accidents; the overweight of the vehicle accelerates the fatigue of the rails and increases the probability of rail breakage; It is very difficult to rescue when a problem occurs; the driver of the combined train has a high workload and requires a high level of control consistency
There is no system and control method for controlling group trains in the prior art

Embodiment Construction

[0069] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0070] The train group control system in the embodiment of the present invention controls the trains according to the train groups, coordinates the trains as a whole, and then obtains the optimization of the group. Therefore, under the premise of not increasing the axle load and the length of the train, only through the change...

Abstract

The present invention proposes a control method and system based on train groups. The train adopts a group control method to further shorten the running interval and improve the driving density. The present invention proposes to adjust the phase based on relative real-time speed, continuous spatial distance and group adaptive adjustment. The integrated MB-VG control method builds the absolute time-relative velocity-dynamic position model to realize the train group control system. The system controls the trains according to the train group, and coordinates the trains as a whole, so as to obtain the optimization of the group. Therefore, on the premise of not increasing the axle load or increasing the length of the train, only through the change of the train control system, the traffic density can be greatly improved and the maximum capacity can be obtained. The time and space of the train group control method of the present invention are more subdivided, the tracking interval can be shortened better, and the tracking density can be improved; at the same time, the group control is considered, and the cooperative control can bring out the collective benefit.

Description

technical field [0001] The invention belongs to the field of train control, in particular to a control method and system based on train groups. Background technique [0002] The existing railway train operation control method is a one-dimensional control method based on space units and with the concept of blockage as the core, which lasts for more than one hundred years. It performs independent space control on a single train. The national railway train control system CTCS-2 (Chinese Train Control System, China Train Operation Control System) and CTCS-3, subway train control system CBTC (Communication Based Train Control System, communication-based automatic train control system), and foreign railway train control systems such as ETCS (European Train Control System, European train control system), etc., the train operation control system is constructed with a single train as the control object. Under this framework, the existing railway transport capacity is close to the th...
