GPS-GSM based Rail Signaling and Tracking System

GPS-GSM based Rail Signaling and Tracking System Abstract: In this paper, we propose a system for monitoring, tracking, and automating the trains. In contrast to the existing methods, we employ a global position system (GPS) and Global System for Mobile communication (GSM). The messages are sent and each train is individually tracked. We utilize signaling techniques like GPS and GSM, which provide information to the loco pilot proactively. The proposed system has advantages in terms of communication range and accuracy with respect to wi-fi based rail tracking method. The work has potential applications in bad weather and emergency situations like collision. Keywords: Train Tracking, Collision Detection, Collision Avoidance, GPS, GSM, Railway Signaling. I. INTRODUCTION Railway tracking in the countries like United States, Russia, China, and India assumes significant attention. The railways traverse the length and breadth of the country and carry over billions of passengers and million tons of freight daily. In recent years, a hectic problem around the world is regarding traffic densities. This is not uncommon in railway sectors either. We often hear about the word train collision and its huge impact on precious human life and time. With great passion for this issue, the paper proposes the solution for this grave problem. Especially if we consider the case of Indian railway, most of the train tracking is based on manual entry from stations. The railway is always looking for the specific tracking methodologies, which will provide prior state of the train before arriving to the station. The GPS-GSM tracking system overcomes many problems like multiple aspect color light signaling, relay interlocking, and various kinds of block working, point operation and train tracking. The proposed system is applicable for reducing the damages to a greater extent and it is helpful to both railway system and loco pilot. Uvaraja et al. presents advanced pre-warning system (Railways). The proposed system is an upgrade of the existing train protection warning system (TPWS) and Anti-collision device (ACD) systems. The system makes use of radio frequency identification (RFID), FLIR cameras and other embedded systems [3]. Immanuel et al. proposes real time wireless based train tracking, track identification and collision avoidance system for railway sectors [4]. Shaik et al. presents rail tracking system (RTS). For transmission and receiving of the information, GPS is utilized. A message exchange link is given between rail tracking system and control room based on the GPS. The location of the train is tracked using GSM technology herein [7, 8]. K. Vidyasagar et al. proposes signaling based system that utilizes radio frequency and infrared technology for train tracking. This paper utilizes a switching logic methodology, technique to meet the issues of the train tracking method. This work also focuses to map the train on the display screen [6]. The above systems have constraints in real time; most of these constraints can be overcome in the proposed GPS-GSM based technique. The objective of this paper is to monitor, track and automate trains based on GPS-GSM techniques. The subsequent section of this paper is organized as follows: In Section II, we describe the GPS-GSM modules used for tracking purposes. Section III discusses the performance evaluation of the GPS-GSM module for tracking of the train. Section IV concludes the paper and discusses the potential future work. II. GPS-GSM MODULES FOR TRACKING AND SIGNALING The proposed system consists of two parts, tracking and signaling. Both tracking and signaling are carried out with the help of GPS and GSM modules. A. RAILWAY TRACKING USING GPS-GSM TECHNIQUE Our proposed method for tracking and signaling relies greatly on the wireless communication. It uses GPS and GSM for the communication between trains and operation centres. When each train gets their own module, it connects using GPS to obtain their position. The module which is mounted on the train sends the position and train details using GSM technology proactively. This data is received by a central sever, which in turn sends this data to the trains on that track and operation centers. Hence, within the required distance, if any train is traversing in a same track can read this data and can calculate the distance the two trains. Therefore, based on the distance between two trains, the various alarm levels are raised, when the distance is less than predefined threshold. Then, the proposed system (Train mounted Module) starts warning the driver to avoid the collision occurrence. The proposed system responds quickly and avoids the train collisions. The Figure 1 illustrates the flow chart of the GSM-GPS based rail tracking system. The distance between the trains can be calculated using latitude and longitude provided by the GPS module. Haversine formula can be used for this calculation and given in terms of inverse tangent formula to obtain the great circle distance between two locations. The formula for calculation of distance using GPS coordinate s is . Where  signaling terminologies: red signifies stop instantly before entering the next track section occupied by an ahead train; yellow shows move ahead with reasonable speed (45 km/h) as far as the signal. Green signal illustrates that the subsequent track is not occupied and the train may enter that particular section at the maximum possible speed. In heavily rush tracks; two other signal terminologies are also utilized. Two yellow lights show the restricted speed, and one yellow and one green light show the reduced speed. The working of our system is illustrated with an example of two trains A and B. Suppose there are two trains A and B on the same track, As the GPS co-ordinates of the signal post are fixed, we directly encode those positions in the module so that when the train A which is ahead of the train B crosses the signal position and signal is changed to red, the signal which is changed is directly fed into the train B using GSM module and we can show the current signal of the signal post on a screen in the locomotive. In this way it is helpful for loco pilots to observe the signal during bad weather and low visibility conditions. III. PERFORMANCE EVALUATION In this section, experimental setup, hardware details, results and their analysis are provided. A. Experimental Setup Main module used in this work is SIM 908 Module, which has GPS, GSM and GPRS combined and Arduino UNO board. Arduino UNO is a microcontroller board based on ATmega328 as shown in Figure 3. It has 14 digital input, output pins and 16 Analog pins. It can be communicated to the computer via USB cable. All sensors and communicating devices are connected using microcontroller. SIM908 is integrated with a GSM-GPRS technique that is of high performance and a GPS engine as shown in Figure 4. The GSM-GPRS technique is a quad-band module that works on different frequencies like EGSM 900MHz, PCS 1900MHz, DCS 1800MHz, and GSM 850MHz. SIM908 utilizes GPRS multi-slot class 10 and class 8 and CS-1 to CS-4 coding schemes are employed herein. The experimental setup is shown in Figure 5. Figure  trains are subsequently calculated using GPS coordinates and warning system as shown in Figure 6, 7 and 8. Signaling of the train is also achieved successfully. Real time results of GPS coordinates on the map are shown in Figure 9 which shows the effectiveness of the proposed system. IV. CONCLUSION AND FUTURE WORK The proposed system provides the promising and reliable output. The tracking system using GPS and GSM modules may enable the rail department to safeguard the human life from accidents. The position and the current status of the signal in the signal post are directly transmitted to the train and can be displayed on the screen. In future this work may be extended for automation and driver-less train using GPS, GSM and GPRS techniques. Real time data of moving trains like speed and current location may be tracked and monitored at the control station. Such real-time information can be utilized for system upgrade so as to avert accidents due to natural calamities such as landslide and cyclone. An additional geographic sensor and interface with geographic information system may be required for the same. Furthermore the analysis of such data is bound to provide us with much deeper insight as to why such accidents take place. Learning from such an analysis can be applied to the system, further improving it over time as their data is collected and studied. REFERENCES [1]. N. V. Chawale, P. J. Kadam, S. N. Khodke, P. L.

Conflict Analysis Essay

Conflict is a difference, a disagreement or clash between ideas, principles or people. In conflict management there are issues that center on interpersonal conflict. This type of conflict is a disagreement between individuals that are connected and explains how what one person does has an impact or effect of the other. 1A PERSONS INVOLVED Sheila (my assistant for 14 years) Valerie (hired as Customer Community Relations Representative) The relationship between these two individuals was great; for 2 years they commonly worked on events together and wouldn’t perceive them as interfering on each other’s turf. Sometimes their workloads would overlap but they were able to work together and get them completed. These two individuals would both work in the same space while engaging in small talk. They often spoke about things each had in common with the other such as their faith, volunteer work, school functions and goals. They acted as though they had never worked together. !B CONFLICT SCENE On Feb. 10th I had the opportunity to facilitate a group session of 11 managers at our main office from 3-5pm to discuss people issues. Sheila attended as usually to work the power Point. At the end of the session most of the people who attended wanted copies of the power Point, however if we just printed the power point it would be in black and white. Therefore, Sheila said quote† Simone I need to use the front desk computer to print in color is that O.K.?† I responded â€Å"Yes†. During the time Sheila used the computer the people that attended the centralized people meeting  was sitting down waiting for their rides. I’m in the conference room packing up while Sheila is getting color printed copies for everyone. This wasn’t something that was planned because it was a holiday. Sheila and I were supposed to be the only two staff in the office at that time. Ms. Valerie dropped by to pick up some papers from the conference room and says to me Quote† I could have done that presentation for you†. I responded† Really, I didn’t think of that because I’ve always used Sheila assist me. Ms. Valerie then left the room. In my opinion this was an informal act and Ms. Valerie’s interaction with Sheila stem from more personal than official relationship. She was focused on Sheila not on how they work together to get things done. Although most of the people had left there were still a few around and it didn’t look good to observe two leaders of our company having a misunderstanding. 1CWHAT TRANSPIRED? Through the glass doors of the conference room I could see something wasn’t right near the front door. I noticed that all the others were gone except Sheila and Ms. Valerie. I could barely hear but, I could see negative gestures coming from Ms. Valerie. Her body language told me she was angry because she was leaning forward with her hand on her hip. Sheila on the other hand, facial expression was of, oh my god what did I do. She looked uncertain and I could tell didn’t want to argue, she looked as though she wanted to avoid the conflict. I saw her twirl around and walk away. Soon after we left the office but I didn’t speak about. Until the next day, I received an email from the office manager about the usage of the computers. The words used in the email had a huge impact on the message that I received, I wanted to just bring my keys to the office and never be there alone again. The choice of words was powerful enough to provoke my trust. So powerful I didn’t even respond to the email. I was totally surprised, this has never happened before. I called Sheila and later that day she explained to me the issue between her and Ms. Valerie, that as Ms. Valerie was leaving she made a statement† You know you shouldn’t be on that computer, there could be legal things you shouldn’t be looking at†. 1D SURFACE PROBLEM In my opinion the surface problem was my choice of words† I always use Sheila to assist me†. The words I used probably made her feel worthless, like she wasn’t good enough. I could have said â€Å"Thanks for letting me know I will let you know next time I facilitate a session†. I would also say the problem could stem from Ms. Valerie needing fulfillment, being part of the sessions would give her recognition because she is passionate about her role. 1EUNDERLYING PROBEM The real problem is that Ms. Valerie is new; she is also the Owners sister and her roles and responsibilities are still unclear and when a person doesn’t have defined responsibilities they tend to want to get into anything to keep busy. Therefore, the Owner needs to make sure that she has a clear cut defined tasks and authority boundaries . In my opinion it wasn’t her place to tell the office manager(Owners Wife) before she actually spoke to myself if she felt that there was some kind of ethic violation. 1F WHICH CONFLICT STRATEGIES WERE EMPLOYED BY EACH PARTICIPANT? a. Cognitive assessment of the situation b. Personality and communication competence No, the next day we both received a text from Ms. Valerie that stated† I TOLD SO WHAT OF IT†. That statement alone confirmed she thought about her own needs and she had dealt with the situation because of who she was related to not her title. 1GOUTCOME The outcome was negative. The next day there was gossip within the organization and the spread of misinformation. This caused Sheila to call the office and ask who said things about her. Then Ms. Valerie contacted her again and told her she did. There was no winner or loser because the situation tainted both relationships and when they finally appeared in the same room it caused an uncomfortable atmosphere. 1H VARIABLES In my opinion arguing is normal, but we have to be careful when arguing because sometimes an argument can hide a much bigger problem. The style and the way we argue can speak volumes towards the way we actually feel. The most important aspect of WIN/WIN is how we handle the argument. Therefore, I think that LISTENING, FACE ENHANCING rather than face attacking and UNDERSTANDING the what/why the other person is saying is a major issue. 2A-2B LEARNINGS of CONFLICT For everything that is still going on wrong with relationships, how we act and think, I am still learning slowly about how to do things better. I am more aware there is some level of differences when the conflict involves two or more people. However, the true disagreement versus what is perceived maybe different from the other person because of our senses. As a matter of fact, this class has taught me that conflict is mostly accompanied by misunderstandings and if we can just understand the truth of the disagreement it will help us solve the right problem and manage the needs of both individuals. This course objectives, lectures and textbook â€Å"The essentials of Human Communication† by Joseph DeVito has taught me that perception doesn’t act alone. It is peoples behaviors, feelings and body language that enhances the threats when there is an disagreement. We must continue to learn how to work on the issues and develop strategies or solutions to manage the disagreement and at the same time manage the conflict. I learned that although this conflict was between two people I was surprisingly a party to it. I just wasn’t included in the disagreement. This conflict was interpersonal. Interpersonal conflict will occasionally happen in the workplace due to natural differences in personalities, beliefs and work ethics. It mostly happens in the workplace and is sometimes more complex because it involves needs, interests, threats and concerns. They also involve ongoing relationships and emotions. This analysis is about an ethical situation that caused an interpersonal conflict which in my opinion was due to jealousy, competition and vicious gossip. REFERENCES DeVito, J.(2014).

The World s Advancement Of The Beauty Industry - 2455 Words

In specifically America, the desire to be considered beautiful has taken over the lives of many individuals. The aspiration to be perfect comes from the immense pressure put on women by society. Individuals are trying to avoid the aging process by getting multiple plastic surgeries done in order to stay  ¨beautiful ¨ and  ¨young ¨. But does being beautiful mean that one has to alter the natural way they appear into something one is not? In our society today, this may perhaps prove to be valid. Everyday an ordinary person sees beautiful faces placed on billboards, magazine covers, television and the media. Even though in most cases photoshop is involved to alter one s physical looks, women, young or old, feel discouraged and form a drive to†¦show more content†¦Due to this fact, many women in Connecticut are seeking alternatives. Instead of paying a lot of money for professional surgery, they are getting the procedures done in hotel rooms and traveling out of the coun try. (Walker). However, this is very dangerous in numerous ways since it can cause major health problems. Doctors may not follow safety precautions such as reusing needles which could spread HIV, Hepatitis and other diseases. Although surgery alters one’s appearance, it can be very helpful for those who would like to transition from their original gender to the one they feel like they identify with. Samantha, who was originally a man but now a woman, shares her story of how plastic surgery helped her transition. When she was just 18 years old, she traveled from Connecticut to Colombia to get breast implants and a nose job. Afterwards, she went to Mexico where she got injections to plump her bottom. These instances where Samantha got cosmetic procedures were not safe since they were done in a different country and in unsafe places, such as hotels.(Walker). Samantha put her life into the hands of individuals whose credentials she had not verified. If by chance something took a wrong turn during the procedure, the clinic did not have any equipment to properly help her. However, the only reason Samantha chose this path instead of going to a safe hospital was because she could not afford it. Samantha states, â€Å"It’s always about saving money† but

A Moratorium On Federal Funding - 861 Words

The Department of Health and Human Services maintained a moratorium on federal funding for research on embryos and fetuses, as well as in vitro fertilization, until President Clinton issued an executive order lifting it in 1993 (Scott p.153). However, Congress banned federal funding for human embryo research by adding legislation known as the Dickey-Wicker Amendment to every appropriations bill for the National Institutes of Health since 1995, making it impossible for the President to overturn the ban without also cutting the cash flow to the NIH (Scott p.154). This restriction remains in place today. On August 9, 2001, President Bush â€Å"clarifies which human embryonic stem cells can be used under federal funding rules† by stating that any lines derived from excess IVF blastocysts before his announcement are eligible for grants (Hopkins 2005). Then in 2009, President Obama lifted the made-before restriction for stem cell lines but maintained the ban on creation and destru ction of embryos for research purposes (Madison.com 2009). With all these restrictions and complications, many scientists started to consider moving their research to countries with more liberal stem cell policies, such as Australia, Japan, and the United Kingdom. To combat this potential brain drain and create jobs within their own borders, states began to enact laws promoting stem cell research.
