title: [Research on the High Efficiency Data Communication Repeater Based on STM32F103].
abstract: OBJECTIVE
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  The design can realize real-time and efficient data communication.
  
  
  CONCLUSIONS
  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.
