From Proprietary Protocols to gRPC: A Major Leap in Tainuo's Heterogeneous Industrial Control Communication Architecture

1. Why We Had to Abandon Our Legacy Proprietary Protocols

For a long time, Tainuo’s industrial control boards communicated with the host computer and print control terminals using self-built proprietary protocols. These protocols were indeed lightweight, flexible, and easy to modify during single-category development. However, as Tainuo gradually moves toward Industry 5.0 standards, our system architecture is evolving into a “universal industrial-grade heterogeneous computing and intelligent control platform.”

Against this backdrop, the legacy proprietary protocols exposed three irreconcilable pain points: prohibitively high multi-language SDK maintenance costs (C#, C++/Rust heterogeneous endpoints required manual parser rewriting), lack of strong type safety boundaries, and difficulty in flexibly extending RPC services across heterogeneous systems.
