Aiming at the demand of intelligent power supply in modern power grid

the ARM STM32 chip is used to design graphical user interface（ GUI） interactive intelligent integrated protector. The basic function design is carried out using the Library Development mode. The interactive is completed by display touch technology

the GUI graphical interface and the STem Win Library Development mode. The micro real-time operating system μC/OS-III is used to carry out the multi-function task planning and task operation management design of the protection system

to realize the real-time and reliable operation of the system. Through the μC/Probe detection program configuring

detecting the CPU usage rate

the rationality of the system task and the design of the application task

the overall running condition of the system

the reliability and real time of the intelligent comprehensive protection software system are verified.
