Multi sensor railway track geometry surveying system
- 1. MULTI-SENSOR RAILWAY TRACK GEOMETRY SURVEYING SYSTEM Abstract: Depending on recent developments in railway systems, high-speed trains are being extensively used, and rail transportation is being increased. Reasons for this increase are high speed, economical, environment friendly, safety, and modern characteristics of railway systems. These characteristics can be continued by periodical maintenance and control measurements. Depending on different factors, deformations may occur on the superstructure of railways. Determining these deformations on time and taking precautions is very important for the safety of railway systems. Existing system: In the existing system, Classical geodetic measurement methods and instruments are used to determine railway deformations. The measurement process with these methods and instruments usually takes a long time. Determining these deformations on time and taking precautions is very important for the safety of railway systems Proposed system: In the proposed system, a railway track inspection system based on Accelerometer and Crack Detection Sensor is framed. The system uses GSM Communication for communicating with the railway station. The accelerometer and crack detection sensor are connected with the PIC Microcontroller. The Accelerometer is used to inspect any deformation in the railway track and the crack detection sensor is used to find cracks on the railway track. Once if any of the two abnormalities is encountered, the system sends an alert message to the control center, where it is stored and retrieved later.
