Design of Smart Home System Based on Zigbee

Constructing efficient, convenient and cozy home environment has become the current hot spot by using Zigbee wireless communication technology. This paper simply introduces ZigBee technology including the architecture and network topology of Zigbee2007/Pro protocol stack firstly, and then proposes a design plan of a remote supervisory control system based on Zigbee2007/Pro protocol stack for smart home applications and shows the hardware and software design of the system. This system uses ZigBee Wireless Technology to build home internal network, and connect a variety of sensors and home appliance controller to Zigbee network node. Various signals collected by a few end-nodes may be delivered by this system to the main control module, which will analyze and process them. Then the main control module transfers this information to internet or cellphone through the Ethernet and GSM/GPRS network to remotely and locally monitor and control family inner environment and household appliances. Furthermore, the working condition of the system can be traced into the SD card.

A suboptimal multimedia remote supervisory control of a robotic cell

This paper deals with the problem of developing a low cost remote supervisory control system with multimedia features of distributed robotic cells. The distributed robotic cells are locally controlled by different vendor systems. In the automated factories, a low cost and not isochronous backbone network is usually installed to transfer process data from the production level to the other ones. The proposed architectural prototype makes possible on different remote platforms a supervisory control with full process database access and field audio/video signal. The case of field vocal messages and animated plant synoptic using the low cost factory backbone network has been considered. On the remote station it is possible to use commercial supervisory control applications. A first case study, the remote supervision of a robotic cell, installed in the University of Naples, has given satisfying results. In addition, this application has shown the possibility of using the prototype for educational and research purposes, making available remote access to laboratories.
