Problems solved by technology

However, this flexible combination structure also has potential safety hazards.
In the past, in the process of railway transportation, it often happened that several carriages of a train were decoupled, commonly known as "car throwing", resulting in the loss of goods and safety accidents caused by out-of-control carriages.

Embodiment Construction

[0031] In this embodiment, the detection method for the train throwing car can be one or more combinations of the following detection methods:

[0032] a. Measure the position parameters of the train head and the train tail in real time, and directly judge the relationship between the distance between the train head and the train tail and the actual train length; b. Compare the speed values ​​of the train head and the train tail; c. Compare the acceleration values ​​of the train head and the train tail; d. Compare the running directions of the front and rear of the train.

[0033] The above four methods can be applied independently, and in order to ensure the accuracy and real-time performance of the detection results, multiple methods can also be applied in combination. For example, when the train is going downhill, only detecting the speed of the head and the tail of the train will have poor real-time performance, and other methods should be used for detection; if the number...

Abstract

A detecting method and warning device for the accident separation of the tail carriage(s) of a running train is disclosed. Said method is chosen from real-time measuring of the position parameters for locomotive and tail carriage to directly judge the relation between the distance from locamotive to tail and the actual train length, comparing the speed of locomotive and the speed of tail carriage, comparing their accelerations, and comparing their running directions.

Description

Technical field: [0001] The invention relates to a control method and device for train safety operation. More specifically, the invention relates to a detection method and an alarm device for a train throwing off in operation. Background technique: [0002] In recent years, with the frequent speed increase of railway trains, the problem that has plagued the Ministry of Railways for many years is: how to ensure the operation and transportation safety of trains. As we all know: a train is formed by connecting several carriages with each other through hooks, which can be loaded and unloaded according to needs, and can be combined flexibly. However, this flexible combination structure also has potential safety hazards. In the past, in the process of railway transportation, it often happened that several carriages of a train were decoupled, commonly known as "car throwing", resulting in the loss of goods and safety accidents caused by out-of-control carriages. Invention conte...
