In rainy season we are much familiar with water clogging wasting a lot of crude oils and other resources which leads to on railway tracks and train delays hence we came up with global earthling. The name maglev is derived from magnetic an amazing invention of storing all the clogged water and levitation. Magnetic levitation is a highly advanced rain water by rain water harvesting and clogged water in a technology. It has various uses. The common point in all tank and using all of it for sanitization and cleaning of applications is the lack of contact and thus no wear and trains. In this project we are using sensors to detect the friction. This increases efficiency, reduces maintenance costs, water clogs and triggering the pumps relevant to it to suck and increases the useful life of the system. The magnetic all the clogs and hear by preventing train delay. levitation technology can be used as an efficient technology 3. As we all know railway station is an extensive platform in the various industries. There are already many countries which consists of fans, upcoming train indicator, Lights, that are attracted to maglev systems. Many systems have been etc. which of course uses electricity. This electricity can be proposed in different parts of the worlds. This paper tries to source to those entire gadget using solar panels which can study the most important uses of magnetic levitation be placed effectively over the platforms roof to generate technology. The results clearly reflect that the maglev can be sufficient electricity. Hence making India a better place and conveniently considered as a solution for the future eco-friendly. engineering needs of the world. So in this paper we’re discussing about magnetic levitation and the uses in II. BASIC METHODOLOGY transportation. Scope Key words: Maglev, Levitation, Wear, Friction, The use of natural resources in our day today life is increasing Transportation This leads to shortage of these resources in the upcoming Generation, mainly in transportation we are wasting a lot of I. INTRODUCTION crude oils and other resources which leads to global earthling. Magnetic Levitation is the latest in transportation technology A train which is capable of floating in mid-Air without any and has been the interest of many countries around the world. support rather than magnetic field [7]. The scope of magnetic A train which is capable of floating in mid-Air without any levitation system is most important in transportation system. support rather than magnetic field. This train doesn't have a motorized engine neither a diesel nor a charcoal engine but uses a theory of a linear motor for its propulsion[5]. Its maintenance cost is very low in terms of traditional engines as there is no contact between train and tracks. Since this train undergoes no friction hence this train is capable of exceeding the speed of 580km/h, thus this train is considered as flying of ground. These types of train are purely for long distance travel and a futuristic invention to reduce on travel time. If a maglev train is implemented in India then Delhi is just 3& 1/2hr away from Mumbai. Talking about smart platforms, we came up with solution for three major issues they are as follows- 1) Wheelchair handicaps to board into the train. 2) Water clogging on railway tracks. 3) GREEN ENERGY Fig.1.Block diagram. 1. Government of India has already taken a great initiative to High Speed Maglev trains are achieved by the add a handicap boogie in a train but one thing they missed combinations of magnetic field. This can be achieved by out is the platform for the wheelchair handicaps. It’s a very Levitation and Propulsion magnets which are embedded in tedious job for those handicaps to board. Hence we came tracks [5]. The levitation magnets help to levitate the train in up with an outstanding invention which wills midair without any support rater then magnetic fields whereas revolutionaries the history. We are handing each and every the propulsion magnets are responsible for the Too & Fro wheelchair handicaps a RFID card which if they swipe in movement of the trains. Guide ways are used to keep the the train or on a platform, an artificial sloping platform is trains on track. RFID technology is used to create artificial platforms for wheelchair handicaps.

This eliminates the need for a separate clog. low-speed suspension system, and can simplify track layout. On the downside, the dynamic instability demands fine track A. What is maglev train and how it works? tolerances, which can offset this advantage. Eric Maglev is a system in which the vehicle runs levitated from Lewthwaite was concerned that to meet required tolerances, the guide way (corresponding to the rail tracks of the gap between magnets and rail would have to be increased conventional railways) by using electromagnetic forces to the point where the magnets would be unreasonably between superconducting magnets on board the vehicle and large. In practice, this problem was addressed through coils on the ground. The following is a general explanation of improved feedback systems, which support the required the principle of Maglev. Magnets interact when opposite tolerances. polarity and repels at same polarity, this repulsive and attractive forces cause of levitation. Magnetic Levitation is described by FARADAY’S and LENZ’S LAW, negative of rate of change of flux with respect to time is equal to electromotive force induced in close circuit. In the public imagination, "maglev" often evokes the concept of an elevated monorail track with a linear motor. Fig.2.EMS model Maglev systems may be monorail or dual rail and not all At balance position both forces are equal that mean monorail trains are maglevs. Some railway transport systems electromagnetic attractive force is equal to gravitational force incorporate linear motors but use electromagnetism only towards downward. for propulsion, without levitating the vehicle. Such trains Net force = Gravitational force (downward) – have wheels and are not maglevs. Maglev tracks, monorail or electromagnetic force (upward) not, can also be constructed at grade (i.e. not elevated). = mg –(퐼/퐻)2 Conversely, non-maglev tracks, monorail or not, can be G-gravitational constant. elevated too. Some maglev trains do incorporate wheels and Kt-magnetic force constant. function like linear motor-propelled wheeled vehicles at b) Electrodynamics suspension(EDS): slower speeds but "take off" and levitate at higher speeds. Electrodynamics suspension system is mainly based on The two notable types of maglev technology are: electromagnetic repulsion and this repulsive force overcome 1. Electromagnetic suspension (EMS), electronically by the gravitational force and allows it to levitate. EDS controlled electromagnets in the train attract it to a system in maglev train frequently used by Japanese magnetically conductive (usually steel) track. engineers. In some configurations, the train can be levitated 2. Electrodynamic suspension (EDS) uses superconducting only by repulsive force. In the early stages of maglev electromagnets or strong permanent magnets that create development at the Miyazaki test track, a purely repulsive a magnetic field, which induces currents in nearby system was used instead of the later repulsive and attractive metallic conductors when there is relative movement, EDS system. The magnetic field is produced either by which pushes and pulls the train towards the designed superconducting magnets (as in JR–Maglev) or by an array of levitation position on the guide way. permanent magnets. The repulsive and attractive force in the a) Electromagnetic suspension(EMS): track is created by in wires or other conducting strips in the This system is also called trans rapid based on EMS track. A major advantage of EDS maglev systems is that they technology. EMS technology introduced by the German are dynamically stable – changes in distance between the scientist in its levitation is obtain electromagnetic attraction. track and the magnets creates strong forces to return the The attractive force between the magnet balances the system to its original position. In addition, the attractive force gravitational force and allow the train to levitate. varies in the opposite manner, providing the same adjustment In electromagnetic suspension (EMS) systems, the effects. No active feedback control is needed. train levitates above a steel rail while electromagnets, attached to the train, are oriented toward the rail from below. The system is typically arranged on a series of C-shaped arms, with the upper portion of the arm attached to the vehicle, and the lower inside edge containing the magnets. The rail is situated inside the C, between the upper and lower edges. Magnetic attraction varies inversely with the cube of distance, so minor changes in distance between the magnets and the rail produce greatly varying forces.
