KABLOSUZ IEEE 802.11B TCP/IP AĞLARINDA MİKRODENETLEYİCİ VE TÜMLEŞİK WEB SUNUCU KULLANILAN BİR BİOTELEMETRİ SİSTEMİ

Bu çalışmada IEEE 802.11b kablosuz yerel alan ağ teknolojisi, bir WebNet ve bir WebRJS-PIC arabirim kartı kullanılarak bir biotelemetri sistemi geliştirilmiştir. Bu çok kanallı sistem bir hastadan ölçülen oksijen saturasyonu, kan basıncı, vücut sıcaklığı ve nabız sayısı bilgilerini herhangi bir alıcıya gönderebilmektedir. Sistemin geleneksel biyotelemetri sistemlerine göre iki önemli avantajı bulunmaktadır. Bunlardan ilki, sistemde IEEE 802.11b kablosuz yerel alan ağ teknolojisinin kullanımı ile geleneksel sistemlerden çok daha hızlı veri iletişim hızı sağlanmasıdır. Geleneksel biotelemetri sistemlerinde özel alıcılar gerektiren vericiler kullanılırken, geliştirilen sistemde alıcı olarak herhangi bir TCP/IP destekli cihazın kullanılabilmesi sistemin ikinci önemli avantajıdır. Verici ünitesinin hafif ve küçük boyutlu oluşu hastalara çok az rahatsızlık vermektedir. Sistem düşük maliyetli, kullanışlı ve geliştirilebilirdir.

A BIOTELEMETRY SYSTEM WITH MICROCONTROLLER AND INTEGRATED WEB SERVER IN WIRELESS IEEE 802.11B TCP/IP NETWORK

In this study, we have developed a biotelemetry system using IEEE 802.11b WLAN technology, a WebNet and a WebRJS-PIC adapter card. This multichannel system is able to transmits measured oxygen saturation, blood pressure, body temperature and heart rate values of a patient to any recipient. Our system has two major advantages different from traditional systems. The first advantage is that by considering traditional systems, faster data rate is provided in our system using IEEE 802.11b WLAN technology. While special transmitters which require special receivers are used in traditional systems, any TCP/IP supported device can be used in our system as system receiver. This is the second major advantage. Because of small dimensions and low weight of the transmitter unit, this unit gives only a little disturbance to patients. This system is low cost, useful and improvable.
