A method for detecting the integrity of a train

Abstract

The disclosed embodiment of the present invention discloses a train integrity detection method, including obtaining the positioning information of the train head and the positioning information of the train tail respectively; When the matched matching error is within the preset range, the train head positioning information and the train tail positioning information; in response to the matched matching error being within the preset range, determine whether the virtual transponder has captured the train head logic state and the train tail logic State, perform logic operations on the logic state of the train head and the logic state of the train tail, and determine the integrity of the train based on the results of the logic operation. It improves the integrity detection efficiency of trains at areas with higher safety requirements such as section boundary points.

Description

technical field [0001] The invention relates to the technical field of track detection, in particular to a train integrity detection method Background technique [0002] With the rapid development of railways in my country today, the requirements for the reliability and safety of railway systems are also increasing. From the perspective of safe and reliable train operation, the study of train integrity detection technology is of great significance and impact on the development of my country's railway industry. [0003] At present, the detection of the integrity of railway trains in my country mainly includes the following methods: [0004] 1. The method of checking train integrity through track circuit occupancy detection 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 wheel presses over the rail. The state of the relay is changed, and the track occupancy check is real...

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.
