The Design and Implementation of Home Automation Universal Terminal Node Based on ZigBee
ZigBee home automation networks is a future trend of intelligent home system. This paper analyses the types and characteristics of home automation terminal node. Based on the chip of CC2530 and Z-Stack protocol stack from Texas Instruments, the home automation universal terminal node is designed. The hardware design adopts modular form with CC2530 as its core, including CC2530 module, sensor module, output driving module and power supply module. For software design, Z-Stack protocol stack is transplanted. Based on the analysis of Z-Stack protocol stack, this paper presents the process of establishing a new ZCL application. Depending on the different types of terminal node, the program flow diagrams are provided. Practice indicates that the design proposal is universal and suitable for terminal node of home automation.
