A multi-parameter signal monitoring system based on Cortex-M3

In order to achieve the simultaneous monitoring of multiple physiological signals and finish the real-time storage and transmission of data, this paper presents a multi-parameter physiological signal monitoring system based on Cortex-M3. The system uses high-capacity SD card for data storage and USB for data transmission, which achieves synchronous storage and display. In addition, it reduces the operating frequency to achieve the goal of low power consumption .The experimental results show that the system is characterized by high-capacity, low-power and high accuracy, which meets the user´s requirements for physiological signal monitoring.
