对EPA控制网络接入ZigBee节点的设计

在EPA网络接入设备中,针对无线局域网、蓝牙等通信技术在工业测控中的传输、功耗、性能和安全性等方面所存在的缺点,在分析了EPA标准和ZigBee技术的基础上,给出了ZigBee节点接入EPA测控网络的实现方案。在AT91R40008的嵌入式系统控制下,对ZigBee到EPA控制网络的网关接入节点进行了软硬件设计,实现了符合标准规范的ZigBee终端EPA网络接入点,并构建了集成EPA和ZigBee的测控网络验证和试验系统。试验验证了该方案的可行性。

Design of ZigBee Node Accessing to EPA Control Network

Aiming at the disadvantages existing in transmission,power consumption,performance and security of communication technologies such as wireless LAN,Bluetooth,etc.,for EPA network access equipment,and on the basis of analyzing EPA standard and ZigBee technology,the implementation scheme of ZigBee node accessing to EPA measurement and control network is given.Under the control of AT91R40008 embedded system,the software and hardware of gateway accessing node for ZigBee accessing to EPA control network are designed,and EPA network accessing point for ZigBee terminal that conforms standard specifications is implemented,and the validation and test system of the measurement and control network integrating EPA and ZigBee is established.The feasibility of this scheme is verified by experiments.
