Research on ZigBee Wireless Sensors Network Based on ModBus Protocol

摘要

The information transmission is transparent for the user in the ZigBee wireless sensors network, which are lack of interactivity and self-constrain. The information in the ZigBee wireless sensors network can not be viewed in a real time by a friendly interface. Modbus protocol is embedded into ZigBee stack, in this way, we can implement interaction well and the information can be viewed in a friendly interface. The paper present the measures to embed the Modbus protocol into the ZigBee stack provided by Chipcon company, which contains address bound mechanism, information centralized storage, and flexible monitoring, by which we can monitor the real time information from the ZigBee wireless network and use some instructions to control the remote device in a friendly interface, which can be used well in the middle and small ZigBee monitoring wireless sensors network. We implement it in the plant physiological ecology monitoring system.
