Independently developed the industrial-grade Modbus data acquisition gateway ThingGateway, enabling data collection, processing, and transmission at industrial sites. Responsible for requirements analysis, hardware selection, architecture design, software development, deployment, and release throughout the process. Adopts a modular microservices architecture, utilizing C/C++, Python, JavaScript, and other languages for cross-language development. Innovatively enables Excel point table configuration and asynchronous multithreaded communication, significantly improving efficiency. The project has successfully been implemented and trialed, and a cross-platform Modbus downstream simulator has been developed.
