HEALTH MONITORING SYSTEM
[attachment=56023]
ABSTRACT
As technology is developing, man becomes more and more technology dependent. We are introducing a project which monitors the vital signs of a human being. This project is useful especially for patients who need continuous monitoring. With the help of this integrated system , one can check human blood pressure, temperature and monitor heart beat.
There will be various sensors such as LM35 temperature sensor, heart beat sensor and pressure sensor.
The system is always ON and is integrated with MATLAB software in a personal computer via serial communication(RS232).
INTRODUCTION
The project titled “HEALTH MONITORING SYSTEM” describes the design of a simple, low-cost microcontroller based embedded system, which can be used to monitor various vital signs in a human body.
An embedded system is a system which is going to do a predefined specified task and is even defined as combination of both software and hardware.
A general-purpose definition of embedded systems is that they are devices used to control, monitor or assist the operation of equipment, machinery or plant. "Embedded" reflects the fact that they are an integral part of the system. In many cases their embeddedness may be such that their presence is far from obvious to the casual observer and even the more technically skilled might need to examine the operation of a piece of equipment for some time before being able to conclude that an embedded control system was involved in its functioning. At the other extreme a general-purpose computer may be used to control the operation of a large complex processing plant, and its presence will be obvious.
All embedded systems include microcontrollers or microprocessors. These systems are however often very simple systems as compared with a personal computer.
The very simplest embedded systems are capable of performing only a single function or set of functions to meet a single predetermined purpose. In more complex systems an application program that enables the embedded system to be used for a particular purpose in a specific application determines the functioning of the embedded system. The ability to have programs means that the same embedded system can be used for a variety of different purposes. In some cases a microprocessor may be designed in such a way that application software for a particular purpose can be added to the basic software in a second process, after which it is not possible to make further changes. The applications software on such processors is sometimes referred to as firmware.
Introduction to applications of embedded system:
Embedded controllers may be found in many different kinds of system and are used for many different applications. The list, which follows, is indicative rather than exhaustive. An item in the list may be relevant to a particular company because either (a) it is or involves a core process or product, (b) it is or involves an ancillary function or service performed by the company or © it refers to a product or service provided by a contractor under some form of agreement and the vulnerability of the supplier may need to be considered.
Embedded systems compared with commercial systems:
The Year 2000 problem in embedded systems differs from the problem in commercial / database / transaction processing systems (often referred to as IT systems) in a number of ways. Firstly the user's problem may much lie much deeper than packages or applications software. It may lie in and be inseparable from systems and operating software and from hardware, i.e. in the platform on which the application software is based. When users of IT systems have hardware or operating software problems they can and should be made the concern of the computer supplier: typically, this is not the case with microprocessors and devices based on them.
Secondly in embedded systems the concern is often with intervals rather than with specific dates: the need may be for an event to occur at 100-day intervals rather than on the 5th day of each month. This has the implication that Year 2000 problems may reveal themselves both before and for some time after 1 January 2000 and not at all on the date itself.
The lifetime of embedded systems tends to be greater than that of commercial data processing systems: they remain in use for longer without alteration to their software. Because their software may therefore be older they are rendered more liable to Year 2000 problems.
SENSORS :
Basically, this project requires three sensors, viz., a temperature sensor(LM35) to measure the heat generated by a human body, a pressure sensor to measure the pressure generated in the Blood Pressure(BP) apparatus, and a heart beat sensor to monitor the electrical signals generated by a human heart.
Since all these sensors output analog signals, an ADC(Analog to Digital Converter) is required to make the microcontroller comprehend them. An ADC such as ADC0808 can be used to convert the analog signals from the sensors to digital signals which can be easily processed by the μC.
LM7805 Voltage Regulator:
The MC78XX/LM78XX/MC78XXA series of three terminal positive regulators are available in the TO-220/D-PAK package and with several fixed output voltages, making them useful in a wide range of applications. Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.
Heart Rate Detection
Cardiovascular Physiology Concept
In order to get better understanding of the algorithm, it is necessary to get familiar with some essential cardiovascular physiology concepts first. The algorithm is specifically developed to detect the heart rate out of arterial and aortic pressure change signal. People should be not strange to this signal because it is the same one which people use every day to measure their pulse pressure by measuring the amplitude. The only difference for this time is that we use it to detect the heart rate information by measuring the period for the signal.The signal is shown as below.
