Research on the High Efficiency Data Communication Repeater Based on STM32F103 / 中国医疗器械杂志

ABSTRACT

<p><b>OBJECTIVE</b>To improve the radio frequency (RF) transmission distance of the wireless terminal of the medical internet of things (LOT), to realize the real-time and efficient data communication, the intelligent relay system based on STM32F103 single chip microcomputer (SCM) is proposed.</p><p><b>METHODS</b>The system used nRF905 chip to achieve the collection, of medical and health information of patients in the 433 MHz band, used SCM to control the serial port to Wi-Fi module to transmit information from 433 MHz to 2.4 GHz wireless Wi-Fi band, and used table look-up algorithm of ready list to improve the efficiency of data communications.</p><p><b>RESULTS</b>The design can realize real-time and efficient data communication.</p><p><b>CONCLUSION</b>The relay which is easy to use with high practical value can extend the distance and mode of data transmission and achieve real-time transmission of data.</p>
