Fast, efficient and reliable data transmission and processing are one of the key technologies for implementing intelligent digital protection devices. Combined with the basic technical requirements of digital protection devices and related equipment for data transmission processing, a high-speed multi-channel synchronization for data sharing among multiple boards in a digital protection device based on a multi-field programmable gate array (FPGA) system is proposed Serial data hard real-time exchange technology. The design and implementation of this technology in digital protection devices are discussed in detail, and the concrete measures of hardware reliability design are pointed out. Digital protection equipment using this technology has been applied in engineering, and this technology can be extended to other digital equipment applications.
