In view of the real-time and intelligent requirements of power supply protector

the integrated power supply protector is designed based on the μC/OS-Ⅲ real-time operating system and the graphical interactive interface emWin

using STM32 processor.According to the functional requirements of the power supply protector

the software and hardware of the system are designed

which are divided into data acquisition and processing

protection action

human-computer interaction and other application tasks with different priorities.Based on the μC/OS-Ⅲ real-time operating system to manage the functions and tasks of the protector

the development of emWin library makes the protector have a beautiful graphical interface and ensure the real-time requirements

at the same time.Use μC/Probe software to detect the system performance parameters.It is verified that the protection system based on μC/OS-Ⅲ and emWin can operate reliably and stably

has high real-time performance

and the design of each subprogram is relatively independent

which is conducive to the later optimization.
