"Automatic Railway Track Security System Using GSM"

Railway Tracking  Security System

                Railways being the cheapest mode of transportation are preferred over he other means.As we all know many railways occurring at unmanned railway track due to the carelessness in manual operations or lack of workers.This project overcomes this problem using simple electronic components to automate the control of railway track.As a railway track  breaks a message will send to the nearest station by GSM modem.

 Automatic Railway Track Security System Using  GSM

Working:The 12V DC is fed to 7805 regulator to fetch +5V regulated output.This regulated voltage is given to all the components to function properly.However,the modem power supply is +5V.This project is based on GSM modem infrastructure.So, as we send any SMS it goes through the GSM system.This message received by the SIM card used in GSM module.The format for sending this message is (#SMS Part here*). The starting string of the SMS is used as the password .As the password is matched, then the SMS arrival is assumed to be valid by the micro-controller otherwise, it ignores the SMS. On the basis of proper initiator and terminator the controller(AT Mega 168) decodes the SMS( # &* ).The GSM modem can be configured for sending an SMS also by configuring at using proper AT command. this feature of the modem has been used in this project.
This project Works in two modes: one in which the system is active in this mode if someone tries to turn on the vehicle, an alert massage to be sent to the registered user.In second mode, the user can turn on the vehicle without any alert.

SMS arrival Display at LCD screen

The SMS arrival status etc properly displayed on LCD screen.proper LCD display ensured through the programming and the LCD interface design.All the configuration command of GSM modem (AT command), authorized mobile number to received SMS (at remote location) and controlling is done through the controller programming means, controller controls all this process as per the program.the interface between micro-controller and the GSM is through UART communication which is serial communication protocol.

"Interactive Wheel Chair"

                 The main purpose of designing such system is to build a non-complex,non-expensive system that can be added to a normal power wheel chair to augment the navigation ability of the user and ensuring a safe journey.It enables a disable person to move around independently,using a touch panel and a voice recognition application which is interfaced with motors.The prototype of the wheelchair is built using a micro-controller, chosen for it's low cost,in addition to it's versatility and performance.A camera mounted on the chair for real time obstacle avoidance.The system has been designed and implemented in a cost effective way so that if our project is commercialized the needy users in developing countries will benefit from it.

Touch panel:Use of touch panel is very much user friendly and requires very less muscles movement from the user.It uses infra-red touch panel technology which is based upon infra-red light.In this technology it uses an array of photo-diodes with corresponding photo sensors on the opposite edges.These diode pair establish an optical grid across the screen.Any object that touches the screen breaks the optical grid lines that cross the touch point,causing drops in the corresponding photo sensors output signals.these drops indicate the touch point co-ordinates.Rather than simultaneously establishing all grid lines, I-R screen controller typically scan through the array.

Working of touch panel:The touch screen is used as input device so to monitor the vehicle the user should press the proper place of touch panel.After that the data can be send to micro-controller and it process and give instruction to motor to move in different directions.By using this embedded technique they can control the movement of their wheel chair which was previously controlled by a person.Now the patient can control the vehicle by touching on the touch panel.During operation the user introduces visible location destinations using a touch panel that display a real time re-construction of scenario in front of the wheel chair(user interface).The user commands are then converted into intermediate goals for the autonomous navigation technology.                                                              

Wheel Chair mechanism:The wheel chair used in this project is a rare wheel drive system powered by two permanent magnet DC motors.Rare wheel drive is traditional and most popular power wheel chair style.They are generally faster than front wheel models.The wheel chair used in this project is a low-end power model which has a light frame that is suitable for indoor use.

 SMS Based  Canal / Pipeline Water Management System

In this  we have checked out the working of CANAL / PIPELINE BASED WATER MANAGEMENT SYSTEM with the help of GSM infrastructure & other electronic components.  

By using this system one can checked out the water level of canal by sending a single massage, and can turn on/off water flow by sending another massage.    

 The 12 V DC is fed to 7805 regulator to fetch +5v regulated output. This regulated voltage is given to all the components to function properly. However, the modem power supply is +12V.

 The idea behind this project is to use the existing GSM infrastructure.  So, all the operations involve the   GSM system also. As we send any SMS, it goes through the GSM system. Any sent SMS can be received if we use a SIM card and GSM module. To operate any GSM modem, we have to use the AT commands to operate them. For example, if any SMS arrives the GSM modem sends the serial data in ASCII format. We can read these data if we connect the modem with the serial port of the microcontroller at the baud rate of 9600. As the microcontroller comes to know that a SMS has been arrived, it can sent a proper AT command to read the SMS. The reading of SMS returns the mobile no of sender, the time and much more information. We have to select the SMS part of the message. The starting string of the SMS is used as the password. As the password is matched, then the SMS arrival is assumed to be valid by the microcontroller otherwise, it ignores the SMS. Here the starting character is the ‘#’ and terminating character is ‘*’. To control the water supply, here we have user three water pumps. We can turn on/off any pump by sending a proper SMS hence we can always control the water level of canal. Additionally we can read the water level also by sending a proper SMS to the system.

Arduino compiler

specifications of the system:

•  It can be used for Canal  Water Management as well as Irrigation purpose.
•  User can operate motor  and can check the water level in tankers from very larger distance same as you massage your relative  from one place to another place
• Since it is based on GSM infrastructure so it can be operated from larger distance wherever network is available.

• The advantage of this system is that it will send you an acknowledgement massage at the mobile number of user which is  already registered.
• The modem send you the massage regarding to the water level itself when water level move from one level to the next.
• This system is able to operate more than one pump at a time.
