plc based railway accident avoiding system
Abstract
Presently in the real time world, commuters are using different types of transport facilities such as flights, trains, buses, cars etc. But majority of the public in our country prefer traveling in trains. The reason may be the comforts available for long journeys and relatively lesser travelling charges. Though the railways has implemented many safety standards for the safe journey, still one can witness some rail accidents and leading to the loss of many precious lives and loss of property. Some of the major reasons for rail accidents are due to the faults on the rail. At present our railways are using manual methods of fault Detection through human inspectors. This work is an attempt to develop an advanced automatic PLC based fault detection technology in railway network to overcome the above problems. The proposed automatic control system makes use of vibration monitoring sensor and ultrasonic sensors to detect the faults occur in the railway track. The hardware components such as PIC16F877A microcontroller, Programmable logic controller (PLC) and GSM are used as advanced controlling and communication elements of automatic fault
detection system
