AI Technical Summary

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.

Embodiment 1

[0037] Example 1: as figure 1 shown:

[0038] The preferred embodiment of the present invention includes an actual operation monitoring unit, a train state receiving unit, a geological data analysis unit, a train approach unit, a natural environment data collection unit, a train information crawling unit, a search strategy unit, and a risk decision unit. Four major parts, each of which performs different functions independently.

[0039] like image 3 as shown, refer to figure 1 and figure 2 , the data must be crawled before the decision in this embodiment, and the error or risk-related data must be identified before the crawling. For example, conventional safety information includes six categories of train speed information, train position information, basic train parameters, line data, and driving environmental conditions. We not only consider these six categories in actual operation, but these six categories are only for trains. In fact, it also includes track safety ...

Embodiment 2

[0050] Example 2: as Figure 4 shown:

[0051] like Figure 4 As shown, in addition to Embodiment 1, in practice, the CTCS-3 train control vehicle real-time information extraction method and device also consider other equipment and the considered data, which includes an actual operation monitoring unit, a train state receiving unit, A geological data analysis unit, a train approach unit, a natural environment data collection unit, a train information crawling unit, a search strategy unit, and a risk decision-making unit; from the perspective of the entire system for the collection and analysis of erroneous data, it is not necessary to These systems are limited, including several industrial cameras (not shown in the figure) and a video capture card (not shown in the figure). In railway construction, high-performance speed sensors are generally used to obtain real-time train running data and convert them into digital signal, which is provided to the onboard computing system. ...

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 fault control based on high-speed railway control technology. Background technique [0002] From the point of view of the safety of CTCS-3 train operation, when a train is in closed operation, the safety-related information can be divided into regular safety information and change safety information; The information is composed of these two kinds of information; for example, conventional security includes six categories of train speed information, train position information, basic train parameters, line data and driving environmental conditions. These six categories are only for train information, while In fact, it also includes track safety information, power supply safety information, etc. Changed safety information involves sudden external influences, which are generally divided into two categories: natural environment and constr...
