Problems solved by technology

[0004] However, there are still some defects in the existing microcomputer protection measurement and control devices.
On the one hand, most of the central processors of existing microcomputer protection measurement and control devices use single-chip microcomputers. Due to the limited computing power of single-chip microcomputers, the computing and processing capabilities of the entire microcomputer protection measurement and control devices are poor and the sampling fre
