【阿里云IoT+YF3300】11.物联网多设备快速通信级联

我们见到的很多物联网设备，大都是“一跳”上网，所谓的“一跳”就是设备直接上网，内嵌物联网模块或者通过DTU直接上网。对于略微复杂的物联网现场，网关通常级联多个物联网设备从而形成一个整体系统（如下图），系统中的各物联网设备分布距离相对较远，不同的设备连接的传感器数量多寡不一，如何快速合理的连接这些设备，并对相应数据进行云端实时传输，如果采用旧有模式进行部署，其结果可想而知，施工难度增加的同时也....

关于物联网平台，网关与则设备的通信问题。

我物联网平台创建了一个网关和10台设备，对用我手中的一个网关和10台设备，我想让这10台设备通过网关与服务器上的设备实现通信，我的网关采用EC20来与服务器通信，但是EC20同意时间只能和一台设备建立连接，比如1号设备通过网关与服务器上的1号设备建立了连接，可以进行数据通信，此时其他设备是处于离线状态，无法进行通信。我想要实现，网关上线后，此网关下挂载的所有子设备上线，并能通过订阅和发布相关主题....
