REAL TIME HEALTH MONITORINGSYSTEM OF REMOTE

PATIENT USING ARM7


2/22

INTRODUCTION

Care of critically ill patient, requires spontaneous & accurate

decisions so that life-protecting & lifesaving therapy can be properlyapplied

Statistics reveal that every minute a human is losing his/her life

across the globe

In India, everyday many lives are affected by heart attacks and

more importantly because the patients did not get timely and proper

help

PROBLEM STATEMENT

This system is wired everywhere

Even after connecting these systems to a particular patient, a paramedical

assistant need to continuously monitor and note down all the vital parameters of a

given patient by keeping track of all of his/her records manually

Adopting such a method is error prone and may lead to disaster in the case of a

human error.

Regular monitoring of patient is not possible once he/she is discharged from

hospitalsThese systems are not capable of transmitting data continuously also range

limitations of different wireless technologies used in the systems.


4/22

Project is based on

Monitoring of remote patients, after he is discharged from

hospital

This energy efficient remote patient monitoring system is

Able to send parameters of patient in real time

It enables the doctors to monitor patients parameters(temp, heartbeat, ECG) in real time

Parameters of patient are measured continuously (temp,

heartbeat, ECG) and wirelessly transmitted

PROPOSED SYSTEM


6/22

To improve the accuracy and to increase the efficiency of the above

processes a real time patient monitoring system based on Wireless

Sensor Networks and a centralized ARM Server integrated with GSM

module is designed.

The system not only help in monitoring the patient when he is in the

bed but also when he is not on bed i.e. when he is mobile

Such a system would constantly monitor important body parameterslike temperature, heartbeat, ECG and would compare it against a

predetermined value set

In the current proposed system the patient health is continuously

monitored by the Mobile Multi Patient Monitoring System and the

acquired data is transmitted to a centralized ARM server using

Wireless Sensor Networks.


7/22

If a particular patients health parameter falls below the

threshold value, a buzzer alert is triggered by the ARM server

Along with a buzzer an automated SMS is posted to thepreconfigured Doctors mobile number using a standard GSM

module interfaced to the ARM server

The Doctor is continuously connected to the ARM server using

GSM Module and he/she can get a record of a particular patientsinformation by just posting a SMS message to the centralized ARM

server.

In such case the patient will get a very quick medicalhelp, saves time and energy of his relatives


8/22

This will reduce treatment time, cost and power consumption to a

greater extent. At the same time, the efficiency of examining ward will

be improved by making the system more real-time and robust

If a particular patients information is required by the doctor, then

he/she can send a SMS to the ARM server mentioning the record

number of a particular patient

The ARM server will first check for a valid doctorsmobile number

which is provided to the GSM module during system boot up time.

If the mobile number requested by the doctor matches with the one

present in the ARM server then a SMS response will be sent back to

the doctor based on the request.


9/22

The hardware design of Wireless Sensor Network Gateway is

based on ARM microprocessor

Through, expanding ZigBee and GSM modules, the platform,can realize the function of wireless sensor network

nodal data collection and transmission. In this the zigbee

modules (using IEEE 802.15a) are considered as zigbee

transceivers. Zigbee modules can communicate and send the information

from one place to another.

Zigbee is connected to center core ARM processor in which

the application runs. This ARM processor acts as the gateway to zigbee and GSM

module.

ARM is connected to GSM module through which text

messages like SMS alerts are sent to the doctors mobilenumber which is configurable


10/22

This project builds an independent system that automatically logs

vital parameters of patients for easy access.

The data is accessible to doctors through mobile device forconvenience

Data of all patients is stored in a common database

Mobility of the equipment is improved by making the equipment

more portable

In the current proposed system the patient health is continuously

monitored by the Mobile Multi Patient Monitoring System and theacquired data is transmitted to a centralized ARM server using

Wireless Sensor Networks


11/22

Temperature, ECG and Heart Beat pulse signals are measured

from the temperature, ECG and heart beat sensors and are

processed by a built-in ARM processor

The processed data are then transmitted by Zigbee

Wirelessly that consumes very low power and is extremely

small in size

Finally the received data is sent to the PC

The graphical user interface programs on the PC are

coded using Visual Basic language


12/22

In the PC a coding is written using Visual basic for transmitting

the information of any abnormal health conditions to the specified

mobile number (of the doctor in charge) in the program through aGSM modem

Embedded C is used for programming the ARM processor

Using GSM modem message is transmitted to the programmedmobile number to the doctor in charge when the measured

temperature exceeds the allowable value or if the pulse measured

is abnormal.

DESIGNING

The designing part includes basically two sections as

Follows:

Hardware designSoftware design

HARDWARE DESIGN

It includes

Power supply design5 v- for temperature sensor circuit, heartbeat

circuit, RS 232 connector circuit

+/- 9 v-for ECG sensor circuit

TemperatureSensor

Heart beat sensor

ECG sensor

ARM Processor and Zigbee connector circuit


14/22

Upon system boot up, the mobile patient monitor system will

continuously monitor the patients vital parameters like Heart

Beat, body temperature etc and will periodically send those

parameters to a centralized server using ZigBee node

configured as co-coordinator.

If a particular patients health parameter falls below the

threshold value, a buzzer alert is triggered by the ARM server.

Along with a buzzer an automated SMS is posted to the

preconfigured Doctors mobile number using a standard GSM

module interfaced to the ARM server.

The Doctor is continuously connected to the ARM server using

GSM Module and he/she can get a record of a particular

patients information by just posting a SMS message to the

centralized ARM server.

to a greater extent. At the same time, the efficiency ofexamining ward will be improved by making the system more

real-time and robust.

ARM 7 PROCESSOR

The ARM7TDMI-S is a general purpose 32-bit

microprocessor

It offers high performance and very low power consumption

ARM architecture is based on RISC principles, instruction set and

related decode mechanism are simpler than CISC Pipeline

Techniques employed ARM Processor supports both32-bit and 16-bit instructions via the ARM and Thumb instruction

set


18/22

The 3 parameters to be monitored are sensed using

respective sensor and data is feed to ARM7

Embedded devices include two types of processors:

a Microcontroller& a DSP to process signals

In ARM processors, these can be replaced by one single

processorThis unit is the heart of the complete system

It is actually responsible for all the process being executed

It will monitor & control all the peripheral devices or

components connected in the system


19/22

Complete intelligence of the project resides in the software

code embedded in the ARM 7

The code will be written in Embedded C and will be burned

or programmed into the code memory using a programmer


20/22

ZIGBEE

ZigBee is Wireless Networking Technology and is an established

set of specifications for wireless personal area networking (WPAN),i.e., digital radio connections between computers and related

devices

This kind of network eliminates use of physical databuses like USB and Ethernet cables

ZNet 2.5 (Series 2) modules are used

The XBee ZNet 2.5 modules from Digi are more advanced than thepopular XBee Series 1modules, but they require a little additional

work to set up


21/22

SOFTWARE DESIGN

This includes the coding of ARM 7 processor and

coding for downloading of data and for GUI

(Graphical User Interface) on server side

For ARM 7: Embedded c using Keil software

For GUI : VB.Net

For Zigbee: XCTU software for configuring Zigbee

For graphical user interface: Visual studio 2008
