Substation data communication gateway device based on domestic chip

Abstract

The invention relates to a transformer substation data communication gateway device based on a domestic chip, which comprises the following steps of: firstly, analyzing two architectures of an existing data communication gateway machine hardware platform, quickly replacing the domestic chip under the condition of not modifying a product hardware architecture design, and analyzing the performance of the data communication gateway hardware platform under different domestic chip combination schemes; the method comprises the following steps: firstly, constructing a universal platform architecture suitable for a transformer substation software and hardware decoupling data communication gateway machine, secondly, analyzing a driving technology suitable for a high-integration-level chip, proposing a hardware module self-identification technology and a flexible bus design technology, proposing an underlying platform rapid deployment scheme supporting multiple chip schemes, and proposing an underlying platform rapid deployment scheme supporting multiple chip schemes; and finally, aiming at a domestic hardware architecture of a domestic chip scheme, developing a transplantation adaptation scheme of operating system and application system software based on a software definition mode, rapidly migrating gateway machine data from a non-domestic gateway machine to a gateway machine based on a domestic chip for operation, and completing stable transition in a domestic substation data communication development period.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a substation data communication gateway device based on a domestic chip. Background technique [0002] Substation automation is the basis for the measurement and control of the power grid. It brings together a large number of modern information, communication and control technology achievements to realize comprehensive automation functions such as automatic monitoring, measurement, control, and communication with dispatching of primary and secondary equipment in substations. Since the localization process started in the 1980s, substation automation technology has developed rapidly. In less than 30 years, it has successively spanned from centralized to distributed, function-oriented design to interval and object-oriented design, and the development process of substation integrated automation, digital substations and smart substations, realizing the transformation from "f...

AI Technical Summary

Problems solved by technology

More than 95% of substation automation data communication gateway products rely on imported chips, and the demand is huge. Once the supply chain is broken, it will cause huge losses to the entire power industry, and a major accident will occur in the data communication of substations.
