Problems solved by technology

[0010] 2.1. Lack of effective 24-hour dynamic monitoring means
The existing technology cannot truly reflect the dynamic impact of the train on the railway track and the railway subgrade when the train passes, especially when the heavy-duty train enters a curve at high speed, its inertial impact force has an extremely strong influence on the railway track and the railway subgrade. Huge, it is likely to cause damage to the railway track and railway embankment, and it is very easy to cause traffic accidents
However, in the existing technology, it is impossible to perform 24-hour dynamic tracking measurement on the entire railway track under the high-speed running state of the train.
Therefore, prior art obviously can not satisfy the technical requirement of high-speed train safe running
[0012] 2.2. Lack of effective 24-hour static monitoring means
Therefore, prior art obviously can not satisfy the technical requirement of train normal running

Embodiment Construction

[0026] The specific implementation manner of the present invention is further described below through the following examples.

[0027] 1. Establish a measurement benchmark

[0028] For the displacement measurement of any object, a measurement reference is needed to measure the relative displacement information data between the object and the measurement reference. To measure the settlement and tilt displacement of the railway track on the railway, a relatively stable and reliable measurement datum is also required. The easiest way is: on the railway embankment, lay down the measuring datum pile vertically. In this way, the measurement basis for the displacement of the railway track is the measurement basis pile. The measurement reference pile can be made of various materials such as steel and cement, and the structure and driving depth of the measurement reference pile are determined according to different environmental and geological conditions. The basic technical require...

Abstract

The invention relates to a high speed railway automatic measuring monitoring technology. It installs measuring reference stake on railway roadbed, and installs displacement transducer on measuring reference stake. It uses relative displacement between railway and measuring reference stake to gain the railway static and dynamic movement information data. The data would be sent to terminal for displaying. It is the scientific basis of design, constructing, operating, and maintaining for railway conveying. The application of the invention is the basic technology ensure of railway conveying safety.

Description

1. Technical field [0001] The invention relates to a railway traffic safety technology, which is an automatic measurement and monitoring technology for high-speed railway track safety. 2. Background technology [0002] The railway traffic in the world has entered the era of high-speed railway. The maximum speed of the train has reached 515km / h, and the operating speed has generally reached 300km / h. As the speed of the train increases, the huge impact of the high-speed train on the railway track and the railway subgrade is likely to cause damage to the railway track and the railway subgrade, which is very likely to cause traffic accidents. Therefore, with the increase of train speed, the technical requirements for railway track and railway subgrade have also been correspondingly improved. The automatic measurement and monitoring technology of dynamic displacement and static displacement of railway tracks has become one of the key technologies to ensure the high-speed and sa...
