Abstract
With the accelerating pace of social life, population ageing, cardiovascular disease has become the major diseases which are serious threat to human health and life, and such diseases are often unexpected, if not making detection and treatment timely, it will get very serious Consequences. ECG monitor is an important means of detecting such disease. It is very important in protecting the safety of its patients and reducing the mortality rate. By the characteristics and requirements of ECG monitor and pulse sensors. This paper is about the study and design of gathering device of the pulse signal of human body. It design a simple structure, function properly, low power consumption and low prices detectors，which is based on MSP430.
Sensor is designed to:
It should be Micro-machines and can be protable. It should work long time with the common batteries.
After Collecting data, it can conversion and send the data to the service terminal .
Design is:
System is mainly composed of three components, signal acquisition, signal conditioning, data processing and sending. The piezoelectric film called PVDF is used for collecting the pulse signals. By using the circuit that is based on the Analog Devices AD620 and OP07 amplifier. ECG signal will be amplified. Finally we use the MSP430 microcontroller as a core chip, and do analog-digital conversion with its own A/D converter, then send the date to the designated terminal by wireless data modules.
