Introduction:
The project aims in designing a system which alerts the railway authorities when any fire accidents occurs in the train and this system also provides an immediate effect which controls fire using controlling system. The project mainly helps to avoid accidents which usually occurs when trains crosses the signal although when it is indicating RED color to stop it.
The train signaling lights need to be manually operated through control buttons. Control buttons are used to control the operation of application of project. If the signal is red the Zigbee module continuously transmits the information in its region of operation. When the train comes into the signal point region then the Zigbee module in the train receives it and automatically stops the train. When the signal is green the driver should start the train manually.
The module in the train has a temperature sensor which continuously monitors the temperature. The temperature is read by the ADC (Analog to Digital Converter) module of the microcontroller Unit. This ADC data is processed and converted into the actual temperature reading by the microcontroller in the train. If the temperature exceeds threshold level (Fire accidents) then the Zigbee module in the train transmits this information as an alert to the railway station authorities. Also, starts the fire extinguishing system automatically. The Microcontroller which is the controlling device of the whole system is programmed using Embedded C language.
Project Overview:
An embedded system is a combination of software and hardware to perform a dedicated task. Some of the main devices used in embedded products are Microprocessors and Microcontrollers.
Microprocessors are commonly referred to as general purpose processors as they simply accept the inputs, process it and give the output. In contrast, a microcontroller not only accepts the data as inputs but also manipulates it, interfaces the data with various devices, controls the data and thus finally gives the result.
The “ADVANCED RAILWAY SECURITY SYSTEM” using PIC16F877A microcontroller is an exclusive project which is used for auto controlling of train depending on the signal indication from signal point alerts through voice announcements using voice module and also alerts at the railway station when any fire accident occurs to the train.
The project “ADVANCED RAILWAY SECURITY SYSTEM” was designed such that the train can be auto controlled from the signal point using RF wireless communication. The system also alerts when there was any fire accident occurred to the train at near by railway station automatically using wireless RF communication system. The system also alerts through both visual and audible using voice module and LCD display unit when the train reaches the particular station.
