In order to achieve non-invasive and rapid detection of pulse signal, a real-time detection system of photoelectric pulse signal based on C8051f020 Single Chip Micyoco(SCM)is proposed in this paper. This detection system can conduct A/D conversion and data processing on pulse signals. According to pulse signal features, pulse rate can be calculated and displayed in real time. This system has non-invasive, convenient and simple operation advantages, which provides important significance for achieving real-time detection of pulse signals.Pulse signal detection system is used to extract the pulse signal based on reflective photoelectric pulse sensor. It consists of I / V conversion circuits, amplifier circuits, filter circuits and voltage follower circuits.The pulse signal is sent to the Bluetooth module through UART interface after processing of SCM and transmitted in real-time. At the mobile terminal, real-time pulse is transmitted to the phone via bluetooth, on the physiological parameters recorded and analyzed.In C8051F020 MCU, pulse signal acquisition, analog-digital conversion processing, pulse rate display, and the pulse signal wireless transmission are inplemented in programming. While at the mobile terminal, C# is used to program the pulse data display software, analysis function which can be used to tell whether the physiological parameters of the testee are normal is added .C8051F020 microcontroller as the host control BF10-A system composed of the Bluetooth modulecan be used for wireless transmission and detection of pulse signals .Pulse signal detection system uses reflex pulse transducer to collect the pulse signal. After the signal collection, circuit regulation and microcontroller processing, pulse signal can be easily dynamic real-time acquired. Remote medical care system uses wireless communication technology, which can save complex interconnects, facilitate again, save the using space. Pulse signal can be very conveniently sent to mobile phones for receiver through bluetooth module, and the real-time receiving pulse signal be analysed in the physiological parameters. Through the test, this system in medical care system that using bluetooth technology for wireless test control is proved to be feasible, and laid a good foundation for the popularity use of future mobile medical ward field.
