Abstract Railways are providing Eco-Friendly transport system for the mankind. Train accidents can happen very often due to safety violations which results from human errors or limitations in the operation of the existing system and also due to equipment failures’. Our project is fully concentrating on avoiding train collisions and ensures passengers safety through android system integrated with ultrasonic and MEMS sensor based control system inbuilt in the train. Emergency alerts can be sent through traditional tele-communication systems such as Walkie-Talkies or other communication devices. However, Collision avoidance systems using IR sensor and anti collision device are being used by the Railway sector is still facing some problems due to the consideration of some factors such as cost-effectiveness, despite it is increasing the amount spent on implementation of the devices. Currently, to some extent the Konkan Railways has put efforts to provide train safety through Zigbee and Infrared based sensor concepts. Even though it has the disadvantages such as limited range of signal covered and difficulty in their implementation in the real world it is still being used. Hence these drawbacks can be overcome in our project by using android based electronic component for the fast communication with latest technology (ARM-7 LPC 2148) to avoid collision and it gets operated through the GPS /GSM concepts. Here RTOS is ported with ARM7 which deal with much more complicated tasks. Our work will be accepted worldwide because of its effectiveness and its robust communication features.

With the accrued demand for railway services, the overall railway infrastructure has been apace developing within the past 20 years, together with its communication systems Walkie-Talkies or different communication devices. Collision dodging systems on same track exploitation Infrared Sensors (IR) and opposed Collision Device (ACD) by Konkan Railway. The ACD system was statically mounted. Therefore it's found to be ineffective and later it had been intuitive. After geographical sensors have also been used, this makes use of satellites for communication. But the system is more costly and complicated too. The major goal of this project is to avoid the communication delays and provide an efficient way to avoid the collision among the trains. The key feature of this system based on Android, Linux based operating system is to overcome the short range communication. Android was developed by Google and members of Open phone Alliance. Due to Android’s open supply nature, straightforward and powerful fast application development tool for developing native mechanical man applications while not long. Its Performance is comparable to applications written with Java, Object bound programming language. The humanoid Open supply Project is an initiative created to guide development of the humanoid mobile platform. The humanoid platform consists of the OS (OS), middleware and integral mobile applications among GPS communication for establish the location of the train so as to avoid the collision and alert the motive force through mobile communication. 2. LITERATURE SURVEY
In this paper [1], Zigbee based automation also provides only a shorter range of communication. It performs the communication based on gate level signals. If the signals are not get transmitted correctly, then it unable to sense the trains

in the same track. In paper [2], automatic train protection that
helps to forestall collisions with speed restriction and applying
brakes. Safety analysis and analysis of automatic train
protection with simulation is required to boost the system
usability within the business space and offers a style of
automatic train protection machine for radio-based train
system. In paper [3], Inferno package that could be a radically
simplified and revolutionary approach can create a trial to
create the essential PDA applications in Inferno setting ported
on ARM processor. In paper [4], Banica et.al introduced the
ARM success attributable to its outstanding performance,
power (MIPS/Watt) rating and this can seemingly still be its
most important benchmark for future applications and
architecture’s high performance and low power operation. In
paper [5], IR sensors have limitations due to the geographic
nature of the tracks and also used along with Light Emitting
Diode-Laser Dependent Resistor. The Anti Collision Device
system (ACD) by Konkan Railway also lacks in
communication capability between the trains and the control
centers or stations, hence it has been later decommissioned.
These methods of identification of problems have taken more
time to identify the problems.
3. EXISTING APPROACH
In the existing system Konkan railways have planned
associate and enforced an opposed Collision System. The
system failed to take any active inputs from existing Railway
signal system, and additionally lacked in 2 ways of
communication capability between the trains and also the
management centers or stations, thence was later
decommissioned.
Fig -1: Existing System
The ACD system is also found to be ineffective because it
does not considering any active inputs from existing Railway
sign system, and additionally lacks 2 ways in which
communication capability between the trains and also the
management centers or stations, thence has been later
decommissioned.
Fig -2: Existing Technology (Static Device)
Later geographical sensors have additionally been used that
makes use of satellites for communication. However the
system is very complex to implement. In current system,
human error or carelessness might result in severe disasters as
noticed within the past. Short vary of communication, severe
harm to the trains and plenty of individuals were harmed and
died. Manual work additionally concerned to avoid collision
isn't effective.
4. PROPOSED WORK
The ARM7 LPC2148 is getting connected with GSM which is
operate under the power supply of 3volt because it have the
boosting variable capacitors for regulate the current as it
needs. When the objects in the track are monitored by the
ultrasonic sensor which uses the sound waves travel to sense
the object. The waves send by the emitter to bounce off an
object and come back to the receiver.
Fig -3: Proposed System Architecture
Then the RF Module is used to transmit and receive signals
from one section to another. If any objects on the track is
detects by an ultrasonic sensor, RF receive signal from train
section interface with μc.GSM is used to send SMS to
authorized persons as guard, controller station and driver. In
this prototype based system, the ARM7 LPC2148
microcontroller along with the sensor which is used to sense
the object in the track before 2feet.When the sensor detects

that object, it having the sensational threshold of manageable and unmanageable objects.
Fig -4: Proposed Block Diagram If the object is a manageable object then it will not pass the information to anywhere else. Otherwise if it is an unmanageable object, while it gets detected it will send the information through alert system and also forward the message to the mobile in order to indicate the driver, guard, controller station and also to the driver to know the particular status of the track. 5. PROJECT DESCRIPTION This Object Collision Avoidance for Train System consists of ultrasonic sensor, algorithm for sensing the collision, GSM module. 5.1 Ultrasonic Sensor Module The module mechanically sends the wave and mechanically sight whether or not receives the returning pulse signal. If the signals returning, through outputting high level and therefore the time of high level continued is that the time of that from the unbearable transmission to receiving. 5.2 The Algorithm for Sensing the Collision When the collision is detect by using ultrasonic sensor which having the capacity to emit the waves immediately for transmitting and receiving in order to detect the obstacles in the track. The arm controller gets connect with the sensing module to sense the objects in the track. 5.3 GSM Module When the collision is detected through the collision algorithm, the GSM module sends the message to the driver in order to prevent the collisions in the track. 5.4 GPS Module
The sensing information can be transmitted via GPS interfaced with the ARM microcontroller to identify the particular location of the obstacle where it is located can be previously identified and the warning can be given to the driver by means of alarm in order to stop the train.
5.5 MEMS Sensor
Mems is a technology, which is used to detect the tilt of the movable train and it makes a alarm to the driver. They can able to take precautionary measures to save the passenger’s lives. The acceleration of a moving object can be determined by using the following formula: A=dv / dt = d2r / dt2 wherever, dv is that the amendment of the velocity/speed over time dt that is capable the distinction between the initial speed and therefore the final speed of the thing, the dv can be defined as shown below: dV=v1-v0 where v0 is the initial velocity/speed while v1 is the final velocity/speed of the moving object. 6. REALIZING When a train reaches a lane, the obstacle present in the track is observed by the sensor. The function of the microcontroller in this application is to act as an interpreter between the hand gesture and the end application. According to the mobility of the Obstacle it can be classified into manageable and unmanageable category. If it’s a manageable object (leaf, paper…) then it can be detected alone, but if it’s a unmanageable object then the alert data is sent to the Driver, guard and control room .Here we use LPC 2148 which consume very low power for its operation purpose. The regulator will take 3V power supply for its operation, through GSM Module the detected information is sent to the Android Hand held devices. In case of emergency purpose through GPS module the control room persons can easily point out the geographical location of the train and rescue operation can be carried out in robust and effective manner. Abnormal train running can be identified by use of the MEMS technology with this micro kit and if this situation occurs then Buzzer get activated so that the abnormal driving can be overcome. The train can be activated in the traditional system itself While the passenger safety can be attained through the train obstacle collision warning system is implemented in a Micro kit oriented Android System and basically to check whether the vehicle is being driven to the destination in real time through the route deviation examination. The warning sign for abnormal running will be a buzzer sound. 7. EXPERIMENTAL RESULT The scenarios of accident in Train are due to object collision. Our device detects the manageable and unmanageable objects in train track and sent the message to mobiles. The following figure:4 shows the implementation of our proposed work.
