摘要
本文介绍了一种基于嵌入式Linux操作系统和4G通信技术的无线网关。网关实现无线传感器网络通信、串口通信、4G移动通信以及自身与数据采集节点的无线通信,实现无线传感器网络到4G网络的协议转换。硬件上可根据实际需要搭配多种不同频率的无线通信模块、4G模块;软件上采用嵌入式Linux操作系统。测试表明,该网关具有实时传输能力强、丢包率低、硬件模块可变、二次开发方便、通用性强等特点。
This paper describes a wireless gateway which is implemented based Linux OS and the fourth generation mobile communication technology. This Gateway worked by the communication of wireless sensor network,,serial port,4G mobile and itself, the data acquisition node, According to actual requirements,the hardware can adopt wireless communication data accessing module at different frequencies ,4G module;And the software based on Linux OS.Tests show that the gateway is characterized by real-time transmission,low packet losing rate,pluggable hardware module, secondary development and good versatility.
