A NOVEL APPROACH RAILWAY TRACK DAMAGE

DETECTION ROBOT USING GPRS TECHNOLOGY

ABSTRACT:

The Transportation of train always depends on railway tracks (rails) only. If there is a crack in these rails, it creates a major problem. Most of the accidents in the train are caused due to cracks in the railway tracks, which cannot be easily identified. Also it takes more time to rectify this problem. In order to avoid this problem, we are using the crack detector robot, which detects the crack in the rails and gives SMS alert about crack location on track.

In India, most of the commercial transport is being carried out by the railway network and therefore, any problems in the same has the capacity to induce major damage to the economy-notwithstanding the societal impact of loss of life or limb. This paper proposes a cost effective yet robust solution to the problem of railway crack detection utilizing a method that is unique in the sense that while it is simple, the idea is completely novel and hitherto untested. The paper discusses the technical and design aspects in detail and also provides the proposed robust crack detection algorithm. The paper also presents the details of the implementation results of the RRCDS utilizing Simple components inclusive of a GPS module based GSM Modem based crack detector assembly. The proposed scheme has been modeled for robust implementation in the Indian scenario.

The core of the proposed crack detection scheme consists of a Infrared Diode (IR)-IR received assembly that functions as the rail crack detector. The principle involved in crack detection is the concept of IR. In the proposed design, the IR LED will be attached to one side of the rails and the IR receiver to the opposite side. During normal operation, when there are no cracks, the LED light does not fall on the Receiver and hence the output at receiver is high. Subsequently, when the LED light falls on the Receiver, the output at receiver is low. This change in output indicates the presence of a crack or some other similar structural defect in the rails. In order to detect the current location of the device in case of detection of a crack, a GPS receiver whose function is to receive the current latitude and longitude data is used. To communicate the received information, a GSM modem has been utilized. The function of the GSM module being used is to send the current latitude and longitude data to the relevant authority as an SMS. The aforementioned functionality has been achieved by interfacing the GSM module, GPS module and IR arrangement with a microcontroller. The robot is driven by DC motors.

In this project we are using GPS module to find the latitude and longitude of present location, the output format of GPS module is UART with baud rate is 9600 bps. For SMS service we are using SIM300 GSM module and the output format of GSM module is UART with baud rate is 9600 bps. Micro controller plays vital role in this project to communicate with all the modules and takes the necessity action.
