DESIGN AND
IMPLEMENTATION OF COMPUTER MICRO CONTROLLER BASED HEART BEAT MONITOR
ABSTRACT
The use of microcontroller is in
every field even we can use it in the design and fabrication of biomedical
equipments. A little example is here. The microcontroller at89s51 (8051) is
here used to develop a heart beat monitoring system. By placing your finger in
between a LED and photo resistance, we can detect the pulses of heart, the
analog voltages are further processed with an operational amplifier LM 358,
this chip has two built in OPAMPs. The TTL pulses or digital pulse are then
feed to the external interrupt of microcontroller 8051. By using a software
counter in the code, we can count the pulses, and the result the process is
displayed on an LCD (2 line 16 characters). The schematic circuit diagram of
heart beat monitor is shown below and the code ( c program) in c language using
keil C51 uv3 is also shown. This is only test project and any one can copy from
it.

CHAPTER
ONE
INTRODUCTION
1.1
Background
One of the most difficult tasks
in generating signals is the decoding. It is only when signals are
decoded that it can be used for any essential purpose. Frequency happens
to be one of such signals that require a careful decoding technique. One
important source of signal is the human body, where different types of signals
are generated. Biomedical signal such as the heart beat is very essential
to the medical expert to be able to ascertain the kind of medical issue with a
patient.
This project, Microcontroller
based heart beat monitor is a project that is geared toward the development of
simple tool to assist the medical experts to check the human heart rate before
further diagnosis can be recommended.
1.2
Objectives
The main objective of this project
is to design and Implement Microcontroller based heart beat monitor. It
is also intended to use this means to contribute to the academic research work.
1.3
Justification
If this prototype is fully
developed will be very useful in many areas such as:
a.
Laboratory
experiments for measuring frequency.
b.
Apply
functions to signals being generated.
c.
Applicable
in the hospitals
d.
Educational
purpose especially in reversed engineering.
1.4
Scope of
the Project
This project makes use of a
keypad as the only major input channel. AT89C51 Microcontroller is the
main control device. Multi-channel Frequency generators circuits will be
realized. Simple interface of output/decoded frequency via LCD will also
be built. Programming power of Bascom Basic compiler will be exploited.
1.5
Constraints
One the major constraint of this
work was finance. Another like it was in availability of the required
information.
1.6 Project Report
Organization
This report is organized into
six chapters. The first chapter takes care of introduction. Chapter
two surveys the literature review of this work. In chapter three, the
project analysis was done. The input, processing and output modules are
critically analyzed.
In chapter four, system
implementation was carefully done. Chapter five takes care of Testing and
Implementation. Finally chapter six closes up with summary and
conclusions.
