應用於健康照顧監控之無線網路感測系統
Wireless Sensor Network for Healthcare Monitoring Applications
摘要
本論文主要目標為設計一個無線感測器網絡之醫療監控系統。網絡中 包含三個感測器節點、五個路由器和一個網狀拓撲，使用nRF24L01 2.4GHz 的收發器。每個感測節點可直接傳輸或者透由路由器傳輸數據，並可共享 或共用相同路由器於同一時間進行傳輸數據。此網路目前可處理三種感測 數據：酸鹼值、心電圖及溫度。透過監測酸鹼值及溫度改變，可應用在水 質監測(飲用水、游泳池、水族館…)。並且可用於輔助醫療診斷應用，如 心臟病(心電圖)、胃食道逆流(酸鹼值)、發炎性腸症(酸鹼值)且無須當面 診療，醫生仍可遠端了解病患健康狀況。感測節點使用MEGAWIN MPC82G516A 八位元微控制器，可使用組合語言或C 語言搭配Keil C 規劃程式於其上。 此外並使用Labview 8.5 透過RS232 串列傳輸連結本系統與個人電腦設計 人機介面，顯示酸鹼值、溫度及心電圖，結果會自動解碼並分離成三種類 型分別顯示準確的數據。使用者也可於本系統上透過圖形化128x64 顯示器 即時觀察到心電、酸鹼值及溫度變化。

The main objective of this thesis is to design a wireless sensor network for healthcare monitoring system. This network has 3 sensor nodes, 5 routers and 1 coordinator in mesh topology which are using nRF24L01 2.4 GHz transceiver . Each sensor node can transmit directly data to coordinator or through the routers. Each node can also share or use the same router to transmit data at the same time. This network can process 3 types of sensor: pH, ECG and temperature. It means that this network can be used to monitor the quality of water (drinking, swimming pool, aquarium...) by monitor pH and temperature. It also can help doctor to observe for many types of diseases: cardiopathy (from ECG), gastro-esophageal reflux disease (GERD) (from pH), inflammatory bowel diseases (IBDs) (from pH) …without seeing the patients; or it helps patients who can’t go to the hospital but the doctor still can know their health situation. The MEGAWIN MPC82G516A 8 bit microcontroller will be used as MCU for each sensor node. Assembly & C language in Keil C will be used to program for MCU. In addition, Labview 8.5 will be used to design interface and series port RS232 communication to display the data of pH, temperature and ECG. It will automatically decode to separate 3 types of data to display exactly results. The users can also observe the ECG signal from sensor node with graphic LCD128x64, pH and temperature with LCD 16x2.
