Description

technical field [0001] The invention relates to the technical field of high-speed railways, in particular to a product in the field of risk and failure control based on high-speed railway control technology. Background technique [0002] From the perspective of CTCS-3 train operation safety, when a train is in closed operation, for safety considerations, the information involved in safety can be divided into conventional safety information and change safety information; usually the information involved in safety Information is a mixture of these two types of information; for example, conventional security includes six categories of train speed information, train location information, train basic parameters, line data, and driving environment conditions. These six categories are only information for trains, and In fact, it also includes track safety information, power supply safety information, etc. Changing safety information involves sudden external influences, which are g...

Problems solved by technology

How to collect and analyze mixed safety information, eliminate interference, and extract useful information cannot be solved by traditional methods. The traditional fixed block divides the line into countless track sections, and uses the status of track relays to judge Train occupancy and line vacancy, roughly detect the train position, the positioning error is the length of a block partition

Especially when the train speed reaches 200km / h or more, the emergency braking distance of the train becomes longer. To ensure the safety of the front and rear trains during high-speed tracking operation, it is necessary to continuously, real-time and accurate extract the safety information of the train with as much error as possible. It should be small, so the traditional method of using track circuits to detect train safety information can no longer meet the safety control requirements of high-speed trains, and needs to rely on other technical means to achieve

[0003] Due to the increase of CTCS-3 level equipment, the complexity of the system increases, the transmission path of various information is extended, and the timeliness is affected

At the same time, different data transmissions may collide and cause information errors

In addition, due to the high speed of the train, the system has extremely high requirements on the interface processing capability. Once there is a problem with the interface, it will endanger the driving safety.
