RFID BASED PATIENT INFORMATION SYSTEM

ABSTRACT:

RFID is an acronym for Radio Frequency Identification. This project is a standalone for detecting the missing tags in RFID system using AT89S52 microcontroller. This project is useful in all applications where more than two tags are there. RFID is increasingly used with biometric technologies for security. Primarily, the two main components involved in a Radio Frequency Identification system are the Transponder (tags that are attached to the object) and the Interrogator (RFID reader). Communication between the RFID reader and tags occurs wirelessly and generally doesn’t require a line of sight between the devices.

RFID tags are categorized as either active or passive. This project uses passive tags. Read-only tags are typically passive and are programmed with a unique set of data (usually 32 to 128 bits) that cannot be modified. The reader has three main functions: energizing, demodulating and decoding. The antenna emits radio signals to activate the tag and to read and write data to it.

This Project helps the hospitals to maintain exact patient data and it can be easily recognized when ever the patient revisits the hospital. Here we are using AT89S52 controller as a control unit and 16x2 LCD is used to display the status. EEPROM is used to store the data.

This project uses regulated 5v, 750mA power supply. 7805, a three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12v step down transformer. The RFID module requires a separate +5v power supply.

RFID Based Library Automation System

RFID Library automation is a very innovative and interesting project that can play avital role in library automation. In this project, each student and each book are assigned with an RFID card. If a student wants to daw a book from the library, he has to swipe his Id card and then Book Id card. The system records the book transaction into the specified student account. Whenever he wants to return the book, he has to follow the same procedure. If the student reaches the maximum number of drawls of the books, the system alerts with a message on the LCD.

RFID is an acronym for Radio Frequency Identification. RFID is one member in the family of Automatic Identification and Data Capture (AIDC) technologies and is a fast and reliable means of identifying just about any material object. This project can be used for security purpose where it gives information about the authorized persons and unauthorized persons. This can be applied in real time systems as such in recording the attendance, in the companies, airports for accessing the passports and in industries to know who are authorized. RFID is increasingly used with biometric technologies for security. Primarily, the two main components involved in a Radio Frequency Identification system are the Transponder (tags that are attached to the object) and the Interrogator (RFID reader). Communication between the RFID reader and tags occurs wirelessly and generally doesn’t require a line of sight between the devices. RFID tags are categorized as either active or passive.

Active RFID tags are powered by an internal battery and are typically read /write, i.e., tag data can be rewritten and/or modified. An active tags memory size varies according to application requirements; some systems operate with up to 1MB of memory. Passive RFID tags operate without a separate external power source and obtain

operating power generated from the reader. This project uses passive tags. Read-only tags are typically passive and are programmed with a unique set of data (usually 32 to128 bits) that cannot be modified. The reader has three main functions: energizing, demodulating and decoding. The antenna emits radio signals to activate the tag and to read and write data to it.

The significant advantage of all types of RFID systems is the non contact, non-line-of-sight nature of the technology. Tags can be read through a variety of substances such as snow, fog, ice, paint, crusted grime, and other visually and environmentally challenging conditions, where barcodes or other optically read technologies would be useless. This project can provide security for the industries, companies, etc.

This project uses regulated 5v, 500mA power supply. 7805, a three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12v step down transformer. The RFID module requires a separate +5v power supply.

RFID Based Toll Tax System

ABSTRACT:

RFID is an acronym for Radio Frequency Identification. This project is a standalone Automatic two door interlock control system for toll tax using AT89S52 microcontroller. This project is useful in all applications where two door interlocking is needed. RFID is increasingly used with biometric technologies for security. Primarily, the two main components involved in a Radio Frequency Identification system are the Transponder (tags that are attached to the object) and the Interrogator (RFID reader). Communication between the RFID reader and tags occurs wirelessly and generally doesn’t require a line of sight between the devices.

In this project, the RFID module reader typically contains a module (transmitter and receiver), a control unit and a coupling element (antenna). This module is interfaced with the micro controller and when the card is brought near to the RFID module it reads the data in the card and displays on the LCD.

The aim of this project is to atomize the toll tax collection on highways. RFID reader, tags are used in this project to identify the entry or exit of the vehicle. The RFID reader is placed at the toll tax collecting area and each and every vehicle is provided with a RFID card. Each and every time when we place the RFID card on the reader the current value (in Rs) in the card has to be stored in the EEPROM. Once we pay the tax through RFID card the value of the card get decremented which can shown on 16X2 LCD.

Initially the gate is closed. Whenever any vehicle comes in front of the entry gate, the reader detects the RFID card owned by the vehicle owner and certain value of amount is detected automatically which will be displayed on 16X2 LCD. By using serial communication the data will be processed by the microcontroller and opens the entry gate by rotating the DC motor. After some delay, the gate will be closed.

The user places the RFID card in the RFID reader for collecting the tax, then. Then the exit gate opens for the vehicle to leave. The microcontroller closes the gate only after the vehicle exits out .If certain amount is not there in the card then he/she can renewal the RFID card. Once the amount is successfully deducted from RFID card only the gate opens. And again the RFID reader will be waiting for the next vehicle to enter.

MOST ADVANCE ACTIVE SUSPENSION SYSTEM IN VEHICLES

INTRODUCTION

Traditionally automotive suspension designs have been compromise between the three conflicting criteria’s namely road handling, load carrying, and passenger comfort. The suspension system must support the vehicle, provide directional control using handling maneuvers and provide effective isolation of passengers and load disturbance. Good ride comfort requires a soft suspension, where as insensitivity to apply loads require stiff suspension. Good handling requires a suspension setting somewhere between it. Due to these conflicting demands, suspension design has to be something that can compromise of these two problems.

Active suspension system has the ability to response to the vertical changes in the road input. The damper or spring is interceding by the force actuator. This force actuator has it own task which is to add or dissipate energy from the system. The force actuator is control by various types of controller determine by the designer. The correct control strategy will give better compromise between comfort and vehicle stability. Therefore active suspension system offer better riding comfort and vehicle handling to the passengers. Figure 1.3 shows simple block diagram to explain how the active suspension can achieve better performance. Figure

describe basic component of active suspension. In this type of suspension the controller can modify the system dynamics by activating the actuators.

All these three types of suspension systems have it own advantages and disadvantages. However researchers are focus on the active car suspension and it is because the performance obtained is better than the other two types of suspension systems as mentioned before. For example the passive suspension system the design is fix depend on the goal of the suspension. The passive suspension is an open loop control system. It doesn’t have any feedback signal to correct the error. It means that the suspension system will not give optimal ride comfort. In other side which is active suspension, it has that ability to give ride comfort. This is happen by having force actuator control by the controller. The active suspension system is a close loop control system. It will correct the error and gave the output to the desired level. In this project observation will be made at the vertical acceleration of the vehicle body called sprung mass and tire deflection. By using the right control strategy the ride quality and handling performance can be optimize. Therefore, in this project there

will be modeling for active and passive suspension only.

ØCOMPONENTS

1. A Computer or an electronic control unit (ECU)

Short for Electronic Control Unit, the ECU is a name given to a device that controls one or more electrical systems in a vehicle. It operates much like the BIOS does in a computer. The ECU provides instructions for various electrical systems, instructing them on what to do and how to operate. Below are two pictures of what an ECU might look like, depending on the vehicle.

There are a number of different types of ECUs, including an Engine Control Module (ECM), Powertrain Control Module (PCM), Brake Control Module (BCM), General Electric Module (GEM) and others. Newer vehicles can have as many as 80 ECUs and due to their increasing complexity, the programming involved in developing the ECUs is becoming more challenging to maintain.

2. SENSORS

Linear acceleration sensors, also called G-force sensors, are devices that measure Acceleration caused by movement, vibration, collision, etc. All acceleration sensors operate based on a simple principle in which Newtons second law of motion is applied to a spring-mass system. A mass is connected to the base of the acceleration sensor through an equivalent spring. Since the force between the mass and base is proportional to the acceleration of the mass and the relative distance between them has a linear relationship with the force due to the spring, the acceleration can be calculated from a measurement of the relative position of the mass or force on the spring as it varies with time. Generally, the most common types of acceleration sensors include: piezoelectric, piezoresistive, variable capacitance and variable reluctance.

Automotive Applications of Acceleration Sensors:

Collision detection and airbag deployment: To measure intensity of collision and signal to initiate airbag deployment.
Electronics stability programs and control: Measures acceleration along various axes, (e.g. forward, braking and cornering accelerations, to compute relative movements and regulate them).
Antilock braking systems.
Active suspension systems: Measures longitudinal and lateral accelerations as well as vehicle roll characteristics to change damper characteristics accordingly.
Hill descent/hold control: Measures vehicle inclination and speed to regulate system.
Monitoring Noise,Vibration and Harshness.
Vehicle navigation systems to determining vehicle location, speed, etc.

3. ACTUATOR OR SERVO

A servomechanism, sometimes shortened to servo, is an automatic device that uses error-sensing negative feedback to correct the performance of a mechanism and is defined by its function. It usually includes a built-in encoder. A servomechanism is sometimes called a heterostat since it controls a systems behavior by means of heterostasis. The term correctly applies only to systems where the feedback or error-correction signals help control mechanical position, speed or other parameters. For example, an automotive power window control is not a servomechanism, as there is no automatic feedback that controls position—the operator does this by observation. By contrast a cars cruise control uses closed loop feedback, which classifies it as a servomechanism.

Uses

Position control

A common type of servo provides position control. Servos are commonly electrical or partially electronic in nature, using an electric motor as the primary means of creating mechanical force. Other types of servos use hydraulics, pneumatics, or magnetic principles. Servos operate on the principle of negative feedback, where the control input is compared to the actual position of the mechanical system as measured by some sort oftransducer at the output. Any difference between the actual and wanted values (an "error signal") is amplified (and converted) and used to drive the system in the direction necessary to reduce or eliminate the error. This procedure is one widely used application of control theory.

Speed control

Speed control via a governor is another type of servomechanism. The steam engine uses mechanical governors; another early application was to govern the speed of water wheels. Prior to World War II the constant speed propeller was developed to control engine speed for maneuvering aircraft. Fuel controls for gas turbine engines employ either hydromechanical or electronic governing.

Other

Positioning servomechanisms were first used in military fire-control and marine navigation equipment. Today servomechanisms are used in automatic machine tools, satellite-tracking antennas, remote control airplanes, automatic navigation systems on boats and planes, and antiaircraft-gun control systems. Other examples are fly-by-wire systems inaircraft which use servos to actuate the aircrafts control surfaces, and radio-controlled models which use RC servos for the same purpose. Many autofocus cameras also use a servomechanism to accurately move the lens, and thus adjust the focus. A modern hard disk drive has a magnetic servo system with sub-micrometre positioning accuracy. In industrial machines, servos are used to perform complex motion, in many applications.

4. ADJUSTABLE SHOCKS AND SPRINGS

A shock absorber (in reality, a shock "damper") is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energyof the shock into another form of energy (typically heat) which is then dissipated. A shock absorber is a type of dashpot.

Description

Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below).^[1]

One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in air cylinders, the hot air is usually exhausted to the atmosphere. In other types of shock absorbers, such as electromagnetic types, the dissipated energy can be stored and used later. In general terms, shock absorbers help cushion vehicles on uneven roads.

WIND SPEED MEASUREMENT AND ALERT SYSTEM FOR TUNNEL FIRE SAFETY

ABSTRACT:

This application describes a system for wind speed measurement and alert.This application is implemented with the help of two sections one is transmitter section which is responsible for monitoring the environment temperature using temperature sensor and depending upon the variation in temperature the speed of the wind changes automatically and whatever the temperature is changed in the transmitter section is displayed on the 16x2 LCD and parallely is is transmitted to the receiver section and displayed on the PC using Zigbee communication.In the transmitter section the temperature sensor is connected to the LPC2148 controller and this controller is responsible for manipulating the entire application.

The LPC2148 are based on a 16/32 bit ARM7TDMI-S™ CPU with real-time emulation and embedded trace support, together with 128/512 kilobytes of embedded high speed flash memory. A 128-bit wide memory interface and unique accelerator architecture enable 32-bit code execution at maximum clock rate. For critical code size applications, the alternative 16-bit Thumb Mode reduces code by more than 30% with minimal performance penalty. With their compact 64 pin package, low power consumption, various 32-bit timers, 4- channel 10-bit ADC, USB PORT,PWM channels and 46 GPIO lines with up to 9 external interrupt pins these microcontrollers are particularly suitable for industrial control, medical systems, access control and point-of-sale. With a wide range of serial communications interfaces, they are also very well suited for communication gateways, protocol converters and embedded soft modems as well as many other general-purpose applications.

This project uses two power supplies, one is regulated 5V for modules and other one is 3.3V for LPC2148. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.

RFID BASED ATTENDANCE SYSTEM

ABSTRACT

RFID is an acronym for Radio Frequency Identification. RFID is one member in the family of Automatic Identification and Data Capture (AIDC) technologies and is a fast and reliable means of identifying just about any material object. This project can be applied in real time applications such as for recording the attendance. This system can be used in big companies, industries, colleges, schools, etc where there are many numbers of candidates available. This system helps us in recording the attendance of a person easily within fraction of seconds. RFID is increasingly used with biometric technologies for security. Primarily, the two main components involved in a Radio Frequency Identification system are the Transponder (tags that are attached to the object) and the Interrogator (RFID reader). Communication between the RFID reader and tags occurs wirelessly and generally doesn’t require a line of sight between the devices.

RFID tags are categorized as either active or passive. Active RFID tags are powered by an internal battery and are typically read/write, i.e., tag data can be rewritten and/or modified. An active tags memory size varies according to application requirements; some systems operate with up to 1MB of memory. Passive RFID tags operate without a separate external power source and obtain operating power generated from the reader. This project uses passive tags. Read-only tags are typically passive and are programmed with a unique set of data (usually 32 to 128 bits) that cannot be modified. The reader has three main functions: energizing, demodulating and decoding. The antenna emits radio signals to activate the tag and to read and write data to it.

If the data in the card is matched with the data in the program memory then it compares with that ID code and displays as “ID FOUND” along with his/her name on the LCD. After it displays it records the time at which the person has entered into the premises using real time clock (RTC) DS-1307. If the data is not matched then it simply displays as “ID NOT FOUND”.

In this project as we are using an RTC, to set the current time there are two switches provided one for entering and the other for incrementing. Then next one more switch is provided for checking the list of the candidates present. For the data not matched it alerts a person through a buzzer. The RFID module indicates a buzzer whenever it reads the data from the RFID card.

The significant advantage of all types of RFID systems is the non contact, non-line-of-sight nature of the technology. Tags can be read through a variety of substances such as snow, fog, ice, paint, crusted grime, and other visually and environmentally challenging conditions, where barcodes or other optically read technologies would be useless. Hence this project can be very much useful and can be implemented in real time applications for recording the attendance and calculate late comers in the School and Collages.

Smart parking reservation system using short message services SMS

ABSTRACT

The Project Smart parking System using 89S52 Microcontroller is an interesting project which uses 89S52 microcontroller as its brain. The project Smart Parking system is designed to solve the problem of unnecessary time consuming in finding the parking spot in commercial car parking areas. This system is designed in such a way that the users book their parking spots with a short SMS.

In this project the user can send a message to book the parking spot in advance, a GSM Modem placed at the parking end will receive the message get processed by the controller to get display on 16X2 LCD. The system is interfaced with RTC DS1307 to set the timings for preprogrammed time delays such as whether the user wants to park their vehicle. The user has to message the exact time and duration he/she wants to park the vehicle in parking spot.

Control switches are provided for entering the required timings. LCD display is provided to display the alarm times and current time. DS1307 is interfaced to the microcontroller for real timing performance. A 3V battery can be connected to DS1307 to avoid time disturbances caused by power failures.

DS1307 has inbuilt flash EEPROM. Data stored remains in the memory even after power failure, as the memory ensures reading of the latest saved settings by the micro controller. It can retain data for more than ten years.

The SIM placed in the GSM modem will return a feedback message to the user whether the place is vacant or not .Once the user get confirmation message directly user can park the car at the given zone, and this is valid up to a certain grace period only after that the priority will be

given to next user. This type of smart parking system is very advanced and the user can save their valuable time in waiting for the space for the vehicle to get parked.

A prototype of a car park system has been designed to demonstrate the capability of the proposed work. The demonstration has proven the capability of the system to reserve the parking, gain entry to the parking area and hence eliminates the hassle of searching empty parking lots.

This project uses regulated 5V, 750mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.
