Train integrity detection method

Abstract

The embodiment of the invention discloses a train integrity detection method. The method comprises: respectively obtaining train head positioning information and train tail positioning information; matching the train head positioning information and the train tail positioning information with the map track information, and determining the train head positioning information and the train tail positioning information when the matched matching error is within a preset range; and determining whether the virtual transponder captures the train head logic state and the train tail logic state or not in response to the matched matching error being within a preset range, performing logic operation on the train head logic state and the train tail logic state, and determining the train integrity basedon a logic operation result. The integrity detection efficiency of the train at higher safety requirements such as interval demarcation points and the like is improved.

Description

technical field [0001] The invention relates to the technical field of track detection, in particular to a method for detecting the integrity of a train Background technique [0002] Today, with the rapid development of my country's railways, the requirements for the reliability and safety of railway systems are also increasing. From the point of view of safe and reliable train operation, the study of train integrity detection technology is of great significance and influence to the development of my country's railway industry. [0003] At present, there are mainly the following ways to detect the integrity of railway trains in my country: [0004] 1. The method of checking the integrity of the train through the track circuit occupancy detection method is mainly used in CTCS-2 and CTCS-3 train operation control systems. The track circuit mainly affects the current and voltage on the track when the train wheels pass over the rail. As a result, the state of the relay changes...

Problems solved by technology

However, there are still shortcomings such as insufficient query frequency, unable to guarantee real-time requirements, and blind spots in wireless communication, which are easily affected by the environment

[0009] For the above-mentioned method 3, on the one hand, although the method is simple, there are problems such as inaccurate accuracy, susceptible to interference and environmental factors, etc.

[0010] At present, wireless positioning technology based on GNSS satellite navigation, inertial navigation and other multi-sensor fusion has been widely used in our country, and its positioning accuracy is also increasing day by day. There are also higher requirements for the detection of train integrity during train operation. With the rapid development of my country's railway industry, the traditional train integrity detection technology can no longer meet the development needs. Except for the current positioning technology, there is no more accurate and reliable train integrity detection system.
