适合有 OpenHarmony 系统移植或嵌入式软件开发经验，并能使用 Node.js、Node-RED 搭建流程应用的开发者或团队。还需要能够接入 BACnet、Modbus、OPC UA、MQTT 等工业协议，完成数据采集、存储和上报场景。
If the items below still feel unfamiliar, you usually get a better result by preparing first instead of rushing in.
OpenHarmony 应用移植
Node.js 运行时移植
Node-RED 节点开发
工业通信协议（BACnet、Modbus、OPC UA）
MQTT 数据上报
SQLite 本地存储
The real friction is usually not library usage. It is validation, time allocation, and task framing.
核心难点是让 Node.js 和 Node-RED 在 OpenHarmony 上完成移植并稳定运行，同时实际打通多种工业协议，尤其包括 BACnet MS/TP、Modbus RTU/TCP 与 OPC UA。作品还需提供测试用例和报告、可执行软件包、源码、演示视频，并在现场答辩中接受评审。
