[Abstract]:In order to meet the new requirements of modern medicine, a wireless ECG transmission system based on embedded processor LPC2290 is developed, which is suitable for remote first aid or home remote monitoring. The system adopts embedded MCU LPC2290, to collect ECG signal through preamplifier circuit; expandable FLASH data memory and liquid crystal display to save and display ECG data; convenient to carry according to Bluetooth technology, flexible in application. It is suitable for short-range wireless communication technology. Bluetooth interface is used for data communication with PC. The main contents of this paper include the design of ECG preacquisition circuit, LCD debugging, Bluetooth communication design, ECG adaptive filtering and feature recognition. Firstly, the overall structure of software and hardware of the system is analyzed and designed from the point of view of performance index, and the idea of sub-module design is adopted. Secondly, the realization of each function of hardware and software of the system is studied. Finally, the adaptive filtering of ECG is studied. Feature recognition, Bluetooth communication, these three parts are the focus of this paper. The ECG adaptive filtering process uses LMS algorithm and FIR filter to filter out the 50Hz power frequency and baseline drift, and the ECG signal after filtering interference is recognized by QRS wave group. On the basis of spread spectrum communication, the architecture of frequency hopping system and protocol of Bluetooth is analyzed, and Bluetooth HCI communication flow is designed on HCI UART transport layer with ROK101008. Finally, the hardware and software of the system are comprehensively debugged, and the display of Chinese character of RT12864M module and the waveform of VC 6.0 center signal of host computer are given. The research of this paper has achieved the expected results.
