DESIGN OF A ZIGBEE BASED WIRELESS MEDICAL MONITORING
SYSTEM
AIM:
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 information’s, and transmit
them to the control center and give voice acknowledgements.
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
and give voice acknowledgements in up normal conditions, 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:
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.
