The invention discloses a 6LoWPAN smart home system and a method for achieving the same. The system comprises a USB embedded gateway, a plurality of bottom units communicating with the USB embedded gateway through a 6LoWPAN network and a control terminal communicating with the USB embedded gateway in a wired or wireless way. The USB embedded gateway receives data information from the bottom units and uploads the data information to the remote control terminal and receives control information of the remote control terminal and issues the control information to the corresponding bottom units to perform remote control. The communication protocol among the bottom devices, the USB embedded gateway and the remote control terminal is that the uploaded data frame format is divided into three classes: sensor alarm data frames, energy consumption data frames and control feedback data frames, and the issued data frame format is control data frames. The system is simple in structure, high in compatibility, convenient to use, low in cost and easy to extend.

The invention discloses a multi-state wireless gateway system for a multi-state wireless monitoring network. The system comprises a configuration management module, an initialization module, a controller interface task module, a radio frequency task module and an unvarnished transmission task module, wherein the configuration management module is used for configuration management of an initially used gateway and the gateway under operation; the initialization module is used for initializing corresponding functional modules and tasks; the controller interface task module processes data from data cache of a sensor and from a controller interface and receives commands issued by an external controller; the radio frequency task module processes message data sent from a radio frequency gateway and from the configuration management task module; the unvarnished transmission task module is used for data transmission among the modules. The system provided by the invention can achieve data exchange, control and the like among wireless instruments of data transmission in different protocols, so that the problem that multi-state object linkage monitoring and controlling networks coexist and are mutually linked and operated is solved.
