This invention discloses a kind of USB interface control board online refresh method which includes the following steps: A. the embedded soft kernel processor receives the refresh command through the USB module and then fetches the refresh data sent by the epistemic machine and storages it in the embedded soft kernel processor's volatile memory; B. erase the original embedded soft kernel processor firmware or the FPGA allocation document in the non-volatile memory; C. program the original embedded soft kernel processor firmware or the FPGA allocation document in the volatile memory to the non- volatile memory. This invention uses the USB interface to refresh the control board if the medicine device and the control board can refresh the embedded soft kernel processor firmware or the FPGA hardware allocation absolutely through the epistemic machine control at the station of no influence to the user's normal use.
