Problems solved by technology
[0004] However, since different trains usually use a variety of different marshalling lengths, such as 6 or 8 marshalling, the running lines of the trains need to meet the mixed operation of trains with different marshalling lengths, and the existing CBTC system provides trains with timely For mobile authorization, it is necessary to quickly determine whether there are other vehicles hidden in the safe distance before / after the train formation, so usually only one kind of train operation with a fixed formation length is supported on the same operation line, which has caused great harm to the mixed operation of trains with different formation lengths. restricted

Embodiment Construction
[0052] Explanation of relevant technical terms:
[0053] CBTC: Communication Based Train Control, communication-based train control system: Based on large-capacity, continuous two-way communication of train-ground information and train positioning and control technology, train speed control is realized. The continuous train automatic control system is constructed by using the train active positioning technology that does not rely on the trackside train occupancy detection equipment and the continuous vehicle-ground two-way data communication technology, and through the on-board and ground processors that can perform safety functions.
[0054] Accident: An accident is an unintended, unanticipated event that can result in death, injury, or damage to property. This is a dynamic process that begins with a hazardous activity and runs through a series of events in the system, producing unpredictable events in a certain order.
[0055] Train running ahead: For the direction of train...

This application discloses a control method and a CBTC system for the mixed operation of trains with different formation lengths. Before the train enters the wireless communication-based automatic train control CBTC area, it is judged according to the preset screening area whether there is a train in front of the running direction. Other vehicles; when there are no other vehicles in front of the running direction of the train, determine the formation length of the train according to the screening area; judge whether there are other vehicles behind the running direction of the train according to the formation length of the train and the screening area, and determine whether there are other vehicles in the running direction of the train. Provide movement authorization for the train when there are no other vehicles behind in the direction. This application scheme can judge whether there are other vehicles in front of the train through the screening area set, and determine the formation length of the train through the screening area, and then judge whether there are other vehicles behind the train, which can not only provide movement authorization to the train in time and quickly, but also Support mixed operation of trains with different formation lengths.
Description
technical field [0001] The invention relates to the field of control technology, in particular to a control method for mixed operation of trains with different formation lengths and a CBTC system. Background technique [0002] With the rapid development of communication technology, especially radio technology, the train operation control system based on communication technology has been more and more in-depth research, CBTC system (Communication Based Train Control System, automatic train control system based on wireless communication) came into being pregnancy. The CBTC system is based on the two-way wireless communication technology between the train and the ground and the principle of mobile block control to realize the control system of train safety protection. It is used to replace the track circuit as the medium to realize the operation control of the train, and it is more and more widely used in cities. Train safety operation protection in rail transit. [0003] The...
