How do you find cracks in railway tracks?
WORKING: Ultrasonic sensor is used to detect the crack on the railway track by not receiving the echo from the track; if the echo sound is received then no crack is detected on the track. The output of the ultrasonic sensor is given to the microcontroller, which is connected to the GPS, GSM and motor driver IC.
What are the three types of railway track?
In the world there are mainly three types of rail tracks, normal rail track, high speed rail track and subway track.
What are the types of railway track maintenance?
Below are the main types of maintenance:
- 1.Rail grinding.
- Rail replacement:
- Tamping.
- Track stabilization.
- Ballast injection (stone blowing)
- Sleeper replacement.
What are the components of railway track?
Typical Railway Track Components Overview – Sleepers, Fishplates, Fasteners and Spikes. Railroad track is known a stable structure that mainly consists of rail sleepers, fishplates and fasteners. It ensures the transportation of trains through providing a dependable surface for their wheels.
What are the types of railway system?
Types of railway/railroad
- Fell mountain railway system.
- Heavy rail.
- Heritage railway.
- Medium-capacity rail system/light rapid transit/light metro/premetro.
- Monorail.
- Mountain railway.
- Plateway.
- Rack railway.
What is meant by track maintenance?
track maintenance in British English (træk ˈmeɪntənəns) railways. the process of maintaining and repairing railway tracks.
Why is track maintenance required?
Track maintenance becomes a necessity due to following reasons. (a) Due to the constant movement of heavy and high-speed trains, the packing under the sleepers becomes loose and track geometry gets disturbed. (c) The track and its components get worn out as a result of the weathering effect of rain, sun, and sand.
How to detect cracks on a railway track?
Ultrasonic technique is the most effective method which detects cracks on a railway track. An android application will be developed to intimate about the rail cracks. As and when a rail crack is detected by the crack detection system, the corresponding loco pilot will be intimated through a pop-up message.
How to detect crack in railroad tracks using ultrasonic sensors?
In the system crack in the tracks is detected by means of sensor and Arduino microcontroller, measuring distance for two railroads. In this project we have used ultrasonic sensors to detect the crack. The below figure 11 shows system for detecting the crack using ultrasonic sensors.
How much of the railway track length is in need of replacement?
A recent study revealed that over 25\% of the track length is in need of replacement due to the development of cracks on it. Manual detection of tracks is cumbersome and not fully effective owing to much time consumption and requirement of skilled technicians.
What happens when a crack is detected by the crack detection system?
As and when a rail crack is detected by the crack detection system, the corresponding loco pilot will be intimated through a pop-up message. This pop- up notification service will be implementing with the help of GPS module.
