The name maglev is derived from magnetic a tank and using all of it for sanitization and cleaning of levitation. Magnetic levitation is a highly advanced trains. In this project we are using sensors to detect the technology [1]. It has various uses. The common point in all water clogs and triggering the pumps relevant to it to applications is the lack of contact and thus no wear and suck all the clogs and hear by preventing train delay. friction [6]. This increases efficiency, reduces maintenance 3) As we all know railway station is an extensive platform costs, and increases the useful life of the system.

This electricity can technology in the various industries. There are already many be source to those entire gadget using solar panels which countries that are attracted to maglev systems. Many systems can be placed effectively over the platforms roof to have been proposed in different parts of the worlds. This generate sufficient electricity. Hence making India a paper tries to study the most important uses of magnetic better place and eco-friendly. levitation technology. The results clearly reflect that the maglev can be conveniently considered as a solution for the II. BASIC METHODOLOGY future engineering needs of the world. So in this paper we’re Scope discussing about magnetic levitation and the uses in transportation. The use of natural resources in our day today life is increasing Key words: Maglev, Levitation, Wear, Friction, this leads to shortage of these resources in the upcoming Transportation Generation, mainly in transportation we are wasting a lot of crude oils and other resources which leads to global earthling. I. INTRODUCTION A train which is capable of floating in mid-Air without any support rather than magnetic field [7]. The scope Magnetic Levitation is the latest in transportation technology of magnetic levitation system is most important in and has been the interest of many countries around the world. transportation system. A train which is capable of floating in mid-Air without any 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. 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 [3]. 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. Fig. 1. Block diagram Talking about smart platforms, we came up with solution for High Speed Maglev trains are achieved by the three major issues they are as follows combinations of magnetic field. This can be achieved by 1) Wheelchair handicaps to board into the train. Levitation and Propulsion magnets which are embedded in 2) Water clogging on railway tracks. tracks [5]. The levitation magnets help to levitate the train in 3) Green Energy midair without any support rater then magnetic fields whereas 1) Government of India has already taken a great initiative the propulsion magnets are responsible for the Too & Fro to add a handicap boogie in a train but one thing they movement of the trains.

In 1976, S.Yamamura proposed a Magnetic Levitation of 5) Thermal Sensor Tracked Vehicles present status and prospects. There are Two thermal sensors conduct electricity based upon the more than five types of magnetically levitated tracked humidity of the surrounding air. One sensor is encased in dry vehicles. All these types of magnetically levitated tracked nitrogen while the other measures ambient air. The difference vehicles provide the contactless support and guidance to between the two measures the humidity. In our project we are vehicles. In this paper, he proposed such system named as using humidity sensor to detect the humidity and moisture in Magnetic Levitation System. This system has two types one soil in order to trigger the pump to avoid water clogging. is electrodynamics levitation (EDL) and another is 6) RFID electromagnetic levitation (EML). Electrodynamics RFID systems consist of three components: an RFID tag or levitation uses the repulsive force between magnet on vehicle smart label, an RFID reader, and an antenna. RFID tags and induced current in secondary circuit on ground. The contain an integrated circuit and an antenna, which is used to repulsive force is produced when the superconductive transmit data to the RFID reader (also called an interrogator). magnets are moving, and so the train is not levitated at low The reader then converts the radio waves to a more usable speed. Because of this repulsive force in EDL it gives the form of data. Information collected from the tags is then stability problem. In this paper he proposed the EML system transferred through a communications interface to a host which uses the attracting force between the electromagnets computer system, where the data can be stored in a database on vehicles and rails on ground. Because of the attracting and analyzed at a later time. In our project we are using RFID force it gives the inherently unstable levitation system. The technology for handicaps to create an artificial platform for a stability problem is solved by using EML system. To solve wheel chair handicaps to board into the train. When a this problem it needs closed loop control of the magnet handicap swipes the RFID card at station after the trains current in order to obtain stability.
