Description

1. Project introduction

   The transportation industry has developed rapidly in recent years. Railways have become the most important mode of transportation and transportation today. High-speed rails and intercity trains are getting faster and faster. However, with greater speed comes greater danger.

    After the railway is laid, due to long-term use, some soft sections may experience subsidence of the roadbed as time goes by. Moreover, the rail use environment is complex and changeable, and is often affected by wind, snow, earthquakes, mudslides, and landslides. The influence of various factors such as foreign objects in tunnels and geological mutations can easily cause the rails to deform and be covered by foreign objects, seriously threatening the safety of trains. Routine maintenance and regular inspection of railway tracks are particularly important.

2. Principle of the plan

     Railways have become the most important mode of transportation and transportation today, and it is crucial to ensure safe and smooth railway operations. One of the basic tasks is to detect the flatness of the rails. Usually, the inclination sensor can be used to measure the rails, and problem sections can be found and dealt with in time to ensure the safety of train driving. The inclination sensor is a tool that can measure the inclination angle of the relevant system. Its working principle is mainly to measure the component of gravity in the direction perpendicular to the tilted surface when the measuring element inside the sensor is balanced inside the sensor. , since the relationship between this component and gravity is a trigonometric function, the angle value can finally be obtained by using the inverse trigonometric function.

3. WITMOTION plan

    WITMOTION Inclination Sensor Rail Flatness Detection When testing the rail flatness, fix the sensor on the railway plane and use the zero button to achieve the zeroing function before measurement. The data read by the sensor after that is the relative inclination angle relative to the plane. Internal filtering can be used to achieve the goal of measuring inclination in vibration situations. Through the cooperation of two axes, the inclination sensor can measure the subgrade settlement degree at a 360-degree inclination angle and monitor the condition of the subgrade in real time.

   In addition to angle measurement by the inclination sensor, measurement data can also be converted and stored. Usually the entire measurement system is installed on a movable platform. When the platform moves along the rails, the inclination sensor can measure the horizontal inclination angle of the platform. The measurement data is recorded by the relevant storage device movement to facilitate the measurement after the measurement is completed. The slope of the railway track section is assessed to facilitate the determination of whether rectification is needed to ensure safe operation.

    After the railway is laid, due to long-term use, some soft sections may subside over time. In order to ensure the safety of railway traffic, a remote automatic monitoring system for subgrade settlement based on technologies such as sensors and wireless networks is developed. Used to monitor railway subgrade settlement conditions. The monitoring system includes four subsystems: laser automatic measurement of surface settlement, simultaneous automatic measurement of subgrade layered settlement and lateral displacement, automatic measurement of subgrade lateral section settlement, and data acquisition and wireless transmission.
