摘要
针对移动通信系统和无线传感网络异构壁垒,提出了基于4G移动网络与ZigBee网关设计的技术思想,该技术是两种异构网络融合关键技术;网关硬件采用MCF52233为主控芯片,通过其一对串口分别实现连接4G芯片EM376。以及ZigBee芯片MC13213;软件是通过在主控芯片中植入两种异构网络融合的程序代码,从而实现网络数据帧的转换功能;经过应用测试,该网关平均时延7.36ms,丢包率为0.5‰,远低于CCSA规定标准。
According to heterogeneous barriers between the mobile communication systems and the Wireless Sensor Networds, 4G mobile networks and design technical thought of ZigBee gateway is proposed, which is the key technology of the heterogeneous network convergence of the two networks. MCF52233 is used as the main chip of the Gateway hardware, by which 4G chip EM3760 and ZigBee chip MC13213 was connected though a couple of serial connection. Software is the main chip program that is implanted into convergence program code in two kinds of heterogeneous networks, enabling network data frame conversion. Experiment shows, the gateway is provided with high speed, short delay, low packet loss rate and so on.
