Abstract :
In this paper, a kind of blood pressure monitoring system based on double filter is designed and presented. This device provides a useful system for people to measure their daily blood pressure and achieve early diagnosis of hypertension. The pressure signal is collected by the pressure sensor and processed by filter circuit. Pulse wave of body contains a lot of healthy information, so the quality of the pulse wave determines the authenticity of the results. In the process of the actual measurement, pulse wave will be interfered by lots of unwanted signals. Common interference signals include 50Hz power frequency signal, noisy signal from muscles jitter and baseline drift. Therefore, we design a suitable double filter system and get a better signal after filtering. In addition, this design includes a ZigBee wireless transmission module, in order to send Blood Pressure (BP) data to the information system in real time.
