The Disabled Patients Using Embedded Systems Information Technology Essay

The Disabled Patients Using Embedded Systems Information engineering science Essay impediments argon those frightful things you see when you take your eyes attain the goal. This quote was rendered by a famous philosopher Hannah Moore in order to do the Disabled. Of the disenable people those who argon physically challenged, the blind, old people and those injury from diseases such as Osteoporosis and rheumatics face problems in their routine life in the master(prenominal) because of LOCOMOTION.ASTHRA is an machine-driven, dynamic retention mapped robotic fomite ( rhythm chairperson) which enables the disabled to carry on their change of location with ease and confidence. The fomite mainly consists of four basic components including a infix WEB SERVER, DC re wink (WIPER TYPE) with driver circle, an ULTRASONIC transmitter and recipient role to watch over obstacles, a Radio Frequency remote (transmitter receiveR) and Programmable and fudge memory whole. The entire com ponent stooge be viewed as a robotic-fomite fitted with 2 High advocate and high torque travels. These labors atomic number 18 placed at the hub of the fomites tyre and their chief aim is to drive or render fit power to pull the pack of the patient of to move approximately. The twain motors are fixed on the hub of the roves and they are placed in such a manner that they render suitable locomotion ground on the zest of the drug drug user. The most important feature of ASTHRA is the introduce web SERVERS. The use of the embedded web servers is to transfer informations regarding the patients temperature, pulse, ECG and other important incumbent features that postulate to be transmitted during times of emergency. The use of the embedded systems is an added advantage for our system. In our case, a RF remote is provided as an interface between the user and the fomite. The motors are provided with a DRIVING enlistment which is connected to a video MICROCONTROLLER BOARD . The Microcontroller board enables self-propelled reposition MAPPING by utilizing the TRAIN AND set method. Utilizing the ULTRASONIC OBSTACLE DETECTION circuit, the Microcontroller building block programs itself as per the dimensions of a event house/place. The ULTRASONIC TRANSMITTER/RECEIVER driven by the COMPARATOR CIRCUIT enable enhanced Obstacle sensing. Thus ASTHRA combines upon various features which render potent locomotion to the disabled.INTRODUCTION TO THE PROJECTSURVIVAL OF THE FITTEST This is what the world is all about today. Every individual is expected to excel irrespective of his/her disability. ASTHRA is a junto of the automatise fomite and the embedded systems. ASTHRA similarly provides a platform for the automated locomotion fro the disabled. A Disabled person is one who faces upon the challenge of be not able to perform a particular or a basic draw which is rendered upon by a normal individual. Disabled persons are those who are visually impaired, Deaf, Dumb, physically challenged etc. Human life is rudimentary without locomotion.The main aim of ASTHRA is to provide an interface between the patients and their locomotion to the coveted place especially in the hospitals. The added concept of the embedded web servers as well makes effective communication between the hospital record system containing the expatiate of the patients records regarding their modes of treatments Utilizing a suitable decision fashioning thingmabob such as a MICROCONTROLLER, we render effective and AUTOMATED locomotion.A MICROCONTROLLER can be regarded as a COMPUTER-ON a CHIP. Such a microcontroller can be utilized for DYNAMIC remembrance MAPPING, wherein the microcontroller unit programs itself utilizing the TRAIN AND EXECUTE mode. thereof by utilizing this Dynamic memory single-valued function technique we can appreciate of building up fomites which can be AUTOMATED as well(p) as ADJUSTABLE to a particular scenario/environment. This idea of building automated fomites combined with embedded systems for the disabled would revolutionize the existing scenario of manual wheel chair movement which makes a patient to be DEPENDENT on nighone to enable him carry out his locomotion.EXISTING SCENARIOSManual wheel chairs and stretchers are provided today for the in-patients and physically handicapped. These chairs are the special mechanical entities fitted upon with post wheels along with several holders which enable movement from one place to another. The chief(a) disadvantage in this mechanics is the NEED TO BE DEPENDENT on others for locomotion. alike this system is MANUAL, ie it operates completely by humane operation.To conglomeration up the tramp the servers and the entire locomotive unit provides transportation as well as transfer of requirement information. It should be noted that the mechanism of transferring the information regarding the status of the patient while taking him/her from the ward to the intensive c are unit or the Operation theatre automatically is extremely appreciable. The disadvantage of the traditional medical transportation facilities areIt isnt DYNAMIC.There is no mechanism to detect OBSTACLES. The patient involves to be highly alert regarding the obstaclesThe wheel chair cannot reach onto the patient every time.No kind of information could be passed from the existing system.The disadvantages proposed here are successfully overcome in our PROPOSED system.PROPOSED organizationARCHITECTURE OF ASTHRAThe above diagram is a brief limn of the entire system. The specifications are as follows.DCM These are high power DC Motors which are utilized to render necessary power to carry on / throw the patients weight. These are fitted on the hub of the robotic vehicles wheels and they enable to control the motion of the Vehicle. The movement of the vehicle based on the motor is enunciated belowSTATE OF THE RIGHT MOTORSTATE OF THE LEFT MOTORDIRECTION OF MOTIONON tallyMOVES RIGHTOFFO NMOVES LEFTONONMOVES trueOFFOFFSTOPSTable1 Vehicle Movement tableMDC This stands for the Motor Driving Circuit. It is connected to the memory MANAGEMENT UNIT. Based on the control rendered by the Memory management unit, the MDC drives the motor which controls the movement of the vehicles wheels.RF mental faculty This stands for the Radio Frequency Receiver Module which is used to rise the vehicle to a particular place. The patient is provided with an RF remote by which he can summon the chair to whatsoever placeOBST DRV This stands for the Obstacle detection drivers which detect obstacles on the way. Ultrasonic Receivers and Transmitters are fitted upon the Obstacle detection ruse which detects Obstacles on the way. A Buzzer is in whatsoever case fitted to this circuit which beeps when an obstacle is encountered. This Obstacle Driving circuit is run by a COMPARATOR circuit which responds to obstacles.MMU The spunk of the system is the Memory management Unit, which cons ists of a PIC MICROCONTROLLER. It enables DYNAMIC reminiscence MAPPING which enables the vehicle to be AUTOMATED. The MMU controls the other circuits connected. It can be regarded as the centralized system of the Vehicle.EWS (Embedded web server) -The central function unit to string access on an embedded system via sack up browser is the electronic network server. This is used to send the information through the inter-network it maintains for future use.DYNAMIC MEMORY MAPPINGMemory Mapping is nothing but PROGRAMMING your Microcontroller unit to perform the necessary tasks. DYNAMIC MEMORY MAPPING enables a microcontroller unit to program itself according to the present scenario. It uses a technique namely, TRAIN AND EXECUTE. This enables the device to program itself based on the situation. This is utilized to determine the end points of the way of life. ponder the vehicle reaches to the wall of the room and is unable to move forward, if u looker upon the TRAIN circuit the dev ice automatically adjusts its path and traces to the door. Now it stores the acquire co-ordinate values onto its memory and traces the path correctly. This is called as DYNAMIC MEMORY MAPPING TECHNIQUE.There is another schema called as STATIC MEMORY MAPPING. In this schema the microcontroller unit is programmed beforehand. The exact positions of the door, co-ordinates of the house are fixed. The vehicle automatically moves based on the patients wish. But if the place is changed we need to REPROGRAM the microcontroller. So in order to overcome this difficulty we normally prefer DYNAMIC MEMORY MAPPING.SWITCHING CIRCUITThe Switching Circuit consists of a serial of Switches which enable the Vehicle to move based on the patients opinion. These are this instant coupled to the MMU which in turn drives the motor and the entire Vehicle. When the patient enters in a particular choice, the appropriateaction is performed.Thus when the appropriate assemble is pressed upon the adequate moveme nt to the corresponding section is enunciated. excessively the main purpose of ASTHRA is the ability of transferring of information such asBlood pulse rateHeart beat countBlood pressure bole temperatureThe entire above are captured exploitation robotic medical tools which contain suitable detectors detecting any change from the pre-stored values and sends them to the system which controls it. The main aptitude of this robotic vehicle is moving from room to the room with just the control of the rf remote. The embedded web server is utilized for the sole purpose of transeunt message to the internet which is maintained by itself and can be analyse for future references. Also the development of softwares and the implementation of hi-fi robots will verify that automatic causality treatment may be habituated to the patients without the wait on of trained professionals.RF LINKThe RF attach mainly consists of two components.The RF TransmitterThe RF ReceiverThe RF Transmitter is do onto a Remote Control and rendered to the patient. This can be utilized to summon the vehicle to any inclined place.The RF Receiver present at the Vehicle responds to the RF Transmitter remote and follows the Radio Frequency Link path to reach onto the Remote(RF Transmitter)The emblem given from the RF remote instructs the robotic vehicle to arrive at the suitable place needed. This might be a disadvantage as he range of this remote will be lesser, even though the vehicle will attain station points in each room.DIAGRAMThe overall block diagram of the automated vehicle is shown.The remote control is in the hand of the patient and he can summon the vehicle. This remote transmits a RF signal which is received by the RF receiver in the automated Vehicle. Based on the signal received the PIC is programmed to move the wheel chair to the user. The movement of the Vehicle to the person is based on the program embedded in it. The vehicle consist of the ULTRASONIC sensor circuit which is driven by the comparator circuit ( COMP CKT ) as shown in the figure. This detects the obstacle and stops the wheel chair from acquire hit. It produces a sound when there is an obstacle. Depending on the memory map in the PIC the driver H bridge IC drives the DC motor circuit. This DC motor is connected to the hub of the wheel. Using the SWITCHING CIRCUIT the MMU moves the Vehicle in the appropriate direction. The EMBEDDED WEB SERVER circuitry enables to transfer informations onto a centaralized meshing page/Web server.The above diagram shows the brief outline of the movement of the vehicle.Embedded web serversThe most important feature of this take in is the Embedded Web Servers. The need for use Web Servers is to transfer necessary information about the patients even during the process of transferring the patient from one room to other. The embedded Internet integration for remote maintenance and diagnostic as well as the so-called M2M communication is growth with a goodish speed rate. Just the remote maintenance and diagnostic of components and systems by Web browsers via the Internet, or a local Intranet has a very high weight for many development projects. Innumerous development departments people work on completely Web based configurations and services for embedded systems. The remaining eld of the classic user interface made by a runty LC-display with front panel and a a couple of(prenominal) function keys are over. through and through future evolutions in the field of the mobile Internet, Bluetooth-based PANs (Personal Area Networks) and the rapidly growing M2M communication (M2M=Machine-to-Machine) a further innovating advance is to be expected. The central function unit to get access on an embedded system via Web browser is the Web server.For example consider a patient being transferred from the normal ward to the ICU or the OP the ward boy or the patients relatives can press the RF remote. The robotic vehicle would come to that place. If th e normal tenderness beat rate is 72 beats per min and if ASTHRA detects it to be some 45 beats per min (all these happening in the due program of motion) it may be seen that ASTHRA would inform or send information using the embedded web servers. The doctors would adapt to the situation suitably and be on the watch before the patient reaches the destination.key advantages OF THE PROJECTThe key advantages of the project acknowledgeDYNAMIC MEMORY MAPPING TECHNIQUE which enables the vehicle to adjust to any locationThe ability to SUMMON the vehicle to any given place.The patient can be INDEPENDENT without being DEPENDENT on others for his movement. economical Obstacle detection performance due to the presence of ULTRASONIC transmitter/receiver.Efficient communication between the web servers and theHigh power haul up ability is established due to the presence of two High power motors.Easy circuitry wherein the MMU acts as the Central Control unit of the vehicle.FUTURE ENHANCEMENTSTh e pursuit are the future enhancements which we have planned,In the present project, the origin of the vehicle, ie the place from which it has to start is predetermined. In our next venture, we would like to include upon ancestry FINDING ALGORITHMS which would dynamically fix upon its origin. So each day the vehicle can start from different unique locations. Rapid construction of the human activity observation system at low cost is necessary with respect to research into human activities and commercialization. The use of the omni directional ultrasonic sensors is also optimum. The reason for the above is as follows, the omni directional ultrasonic location sensor is useful because the number of sensors to be attached can be reduced.We have also planned to introduced GPS to make our system far amore efficientAlso we have planned to increase the efficiency of the system by using VLSI and other mechanisms in our future endeavors.CONCLUSIONThe automated vehicle is aimed towards the so cial welfare of the disabled. Even though various technologies have been introduces off late, a few alone are aimed towards locomotion. ASTHRA being a venture which is fully based on locomotion fulfills this requirement by rendering an efficient mechanism of locomotion for the disabled. Locomotion which is the essential function for any individual is also made available to the Disabled by the use of ASTHRA. ASTHRA goes on to the despotic level of fulfilling the dreams of the disabled thereby bring them close to the common man. Also ASTHRA eradicates the necessity for the disabled to be dependent on others, thereby making them INDEPENDENT. The complete automated feature of ASTHRA makes it possible to handle it upon any given place under any given circumstances. The dynamic memory mapping feature portrays upon its Self sufficiency and the ability to adjust itself to any given environment. The EMBEDDED WEB SERVERS concept further acts as a square in the crown of ASTHRA. This concept enables the doctors to get fast access regarding the patients. In todays fast and ever-changing world, the quality of services rendered is becoming highly important. ASTHRA caters to this need in a highly effective manner. Also it is 100% user friendly which can be rendered from the fact that it can be summoned to any given place. To help others is to help God himself is a well know saying. Hence by developing ASTHRA we feel that we can help a couple of disabled people thereby rendering a crushed piece of contribution to both the Society and the Country.Being Students of Technology we potently feel that ASTHRA would be a landmark of both Technological as well as Social excellence .If our project could help the disabled and render a peaceful life to them, then the success of our project would have been achieved.
