一、物联网平台设计
1.物联网平台设计
IoT 平台总体设计:
- 物联网平台（IoT）部署在云上，物联网设备通过边缘计算节点接入物联网平台
- 物联网平台采用云原生设计，应用容器化部署，在云端实现容器的调度编排
- 物理网平台实现云边协同，云作为控制平面，边作为计算平台
- 云端物联网平台选择开源物联网平台 ThingsBoard 社区版
- 边缘计算节点选择 ThingsBoard Edge 接入物联网设备
IoT 云边协同设计:
- Kubernetes 在云端部署 ThingsBoard 平台
- KubeEdge 在边缘节点部署 ThingsBoard Edge
- IoT 设备通过 MQTT 协议接入边缘计算节点
- 通过 Kubernetes 、KubeEdge 实现云边协同
2.物联网平台实现
物联网平台（IoT）具体实现：
- 部署 Kubernetes 集群
- 部署 KubeEdge
- 部署 ThingsBoard 集群
- 部署 ThingsBoard Edge 边缘节点
- IoT 设备通过 MQTT 链接 ThingsBoard Edge
- MQTTX 工具模拟物联网设备
