Abstract
This paper introduces a network remote firmware update system based on IAP technology, which aims to solve the problems of low efficiency and high cost in the traditional upgraded medical device firmware (lower computer program) mode, and to improve the portability of the lower computer program upgrade maintenance. In order to better cope with market changes, customer needs, and solve software failures in medical devices, it is necessary to update and upgrade medical device software in a timely manner. Through the IAP technology and Internet communication technology of STM32 platform, this solution can complete the update of all instrument firmware in a short time, which not only saves a lot of travel expenses, mailing costs and labor costs, but also greatly shortens the update time.
