Smart home wireless sensor network based on ZigBee

The invention discloses a smart home wireless sensor network based on the ZigBee. The smart home wireless sensor network comprises an embedded gateway, a mobile terminal device, a ZigBee personal area network and a bus switching module. The embedded gateway is connected to the Internet through a wireless hotspot and is mainly in charge of communication of the ZigBee personal area network and an external wide area network. The ZigBee personal area network mainly comprises ZigBee nodes, an interface switching module, a sensor and a home device. The ZigBee nodes comprise coordinators, route nodes and terminal nodes, and the nodes are in wireless network communication through the ZigBee2007/PRO protocol. Coordinator nodes are in charge of establishing the personal area network, maintaining network information and collecting sensor data collected by the terminal nodes or transmitted home device control instructions coming from the gateway. The smart home wireless sensor network based on the ZigBee can be widely applied to the fields of home security monitoring, home energy saving and home device smart control and the like.
