Modular gateway and submodule connection bus and implementation method thereof

The invention relates to a modular gateway and sub-module connection bus and an implementation method thereof, the connection bus is respectively connected between a main module and a concentrator module and between the concentrator module and the sub-module, and is used for realizing self enumeration, hot plugging and sub-module cascading of gateway sub-modules through control messages, data messages and synchronous messages. Compared with the prior art, the method has the advantages of reducing the cost of using the gateway by the user and the like. 本发明涉及一种模块化网关与子模块连接总线及其实现方法，所述连接总线分别接在主模块和集线器模块之间以及集线器模块和子模块之间，用于通过控制报文、数据报文、同步报文实现网关子模块的自枚举、热拔插和子模块级联。与现有技术相比，本发明具有降低用户使用网关的成本等优点。
