Design of a Wireless Medical Monitoring System
Abstract
The main aim of this project is used Monitoring Terminal and
it can detect the patient's real-time body temperature, heart rate and other
physiological informations, and transmit them to the control center.
PURPOSE
Now days the fast development and popularization of
information processing and wireless data transmission technology, the research
of wireless Medical Monitoring System has became a hot topic with the help of
biomedical sensors. By utilizing the wireless technique to transmit information
between medical sensor and monitoring control center, the free space of
patients is enlarged, and the efficiency of the modern management of hospitals
is improved
DESCRIPTION
Now a day with the increase of biomedical sensor we are
going into this process of detecting the patient's real-time body temperature,
heart rate and other physiological information's .Coming to the main core of
wireless medical monitoring system is the design of wireless monitoring
terminal, and the development of system software. The monitoring terminal
generally consists of three modules: the sensor module, the control module, and
the wireless communication module.
The sensor module is used for acquiring
medical information from the outside, and then converts them to digital
signals. The control module is often compared to the brain of monitoring
terminal, which is in charge of coordinating the task of different modules,
controlling the sensors, processing data, and executing communication protocols.
The wireless communication module mainly deals with the
wireless transmission of information. Nowadays, there are various kinds of
wireless communication protocols. But since the main task of a monitoring
terminal is to realize the transmission of signals such as heart rate, body
temperature, and calling signals the data traffic is not heavy. Moreover,
because the monitoring terminal is worn on patients, which needs to be supplied
by battery, it puts a high demand on the reducing of power dissipation of wireless
transmission module.
Having taken these comprehensive factors into
consideration, this paper chooses the ZigBee technology as the wireless
communication protocol. ZigBee technology is a shortrange, low-rate, low-power
wireless communication technology
TECHNOLOGY:
Zigbee is new wireless technology guided by IEEE 802.15.4
Personal Area Network standard. It is primarily designed for the wide range
controlling applications and to replace the existing non-standard technologies.
It currently operates in 868 MHz band at a data rate of 20Kbps in Europe,
914MHz band at 40kbps in USA, and the 2.4GHz ISM bands Worldwide at a maximum
data-rate of 250kbps. It is used to verify whether user's truncation is
possible or not.
One of the main advantages of this ZIGBEE communication is
that it provides a noise free communication, the amount of noise added in this
type of communication is very less compared to the other wireless
communications
Hence, by implementing this project the monitoring terminal
can precisely check the heart rate and body temperature of patients, and send
them to coordinator and then surveillance center through wireless network.
