- 3. CONTENTS INTRODUCTION BLOCK DIAGRAM HARDWARE COMPONENTS SOFTWARE REQUIREMENTS FLOWCHART WORK PROGRESS
- 4. INTRODUCTION o Wireless monitoring devices can make the biomedical system more convenient. o Wireless technology can be implemented inside biomedical areas where there are several electrical devices that are connected through long cables. o So this project is an implementation of Electrocardiograph (ECG) data acquisition and plotting wirelessly manner
- 6. HARDWARE COMPONENTS ELECTRODES INSTRUMENTATION AMPLIFIER FILTERS MICROCONTROLLER ZIGBEE
- 7. ELECTRODES • The ECG is converted into electrical voltage by electrodes. • The disposable electrodes are attached to the patients skin and can be easily removed.
- 8. INSTRUMENTATION AMPLIFIER The AD620 is a low cost, high accuracy instrumentation amplifier that requires only one external resistor to set gain (Rg). The AD620’s low power, low supply voltage instrumentation amplifier. It is available as 8-lead mini-DIP and SOIC package.
- 9. FEATURES Gain : 10 Power supply : +/- 2.3V to +/- 18V Current : 1.3mA CMRR : 93dB – 110dB Bandwidth : 1.2 kHz
- 10. FILTERS The circuit consist of following filters 1.Band pass filter: It is the combination of HPF and LPF. It is designed to allow the frequency from 0.5Hz to 102Hz. 2.Notch filter: It is used to eliminate the power line interference which occurs at 50Hz.
- 11. BAND PASS FILTER: It allows the frequency from 0.5hz to 102hz.
- 12. NOTCH FILTER Used to eliminate power line interference which occurs at 50hz. This filter rejects one particular frequency while passing all other frequencies.
- 13. MICROCONTROLLER Features: Supply voltage : 2.7 to 3.6v Flash memory : 8KB RAM : 768bytes Timers : 4 (16bits) I/0 Ports : 2 (8bits)
- 14. ZIGBEE Zigbee specification which suits for high level communication protocol used to create personal area network. Zigbee is based on IEEE 802.15.4 standard. Zigbee devices can transmit the data over longer distances by passing the data through a mesh network. XBEE - PRO ZB embedded RF modules provides cost effective wireless connectivity to the devices in zigbee mesh network.
- 15. SPECIFICATIONS Data rate : 250Kbps Serial data rate : 1200bps – 1Mbps Frequency band : 2.4GHz Supply voltage : 2.7 – 3.6VDC Range : 100m
- 16. ECG: 1.The ECG signal represents the electrical activity of the heart. 2.The impulses are originated at SINO ATRIAL NODE that is passed on to the ATRIO VENTRICULAR NODE.
- 17. PROGRAMMING LANGUAGE Embedded C SIMULATION SOFTWARE Proteus INSTALLED AT THE REMOTE NODE 1.XCTU software 2.Oscilloscope GUI 3.Eltima software SOFTWARE
- 18. Flow chart start ec sss Acquiring ECG signals using electrodes Amplification and filtering Ecg signals are transmitted through the zigbee wirelessly zigbee rx get data? Displaying the waveform on PC stop Yes No
- 19. WORK PROGRESS WORK COMPLETED: 1. ECG acquisition is done and it is displayed on CRO. 2. Testing of ZIGBEE is done. 3. The hardware portion is completed. WORK TO BE DONE: 1. coding of the ZIGBEE is to be done. 2. ECG signal has to be transmitted wirelessly. 3. Extraction of BP from ECG is to be done.
