A Low Power Consumption Gateway Design for Private Government Network

随着节能意识的提高,不仅要求网络设备性能而且要求节能。针对这种需求,设计出一种低功耗政务专网网关。硬件上使用支持1.4/1.8 GHz和700 MHz频段专网接入的政务专网模块,使用第五代Wi-Fi模块;软件上提出一种基于状态转移图的能量管理算法,算法可以在没有终端接入Wi-Fi时关闭专网通信模块。测试结果表明:网关的性能接近4G设计极限,提出的算法最高可以节省20.75%的能量;之后构建了设备综合工况,由计算结果可知上行传输越多,算法节能效率越高。

With the improvement of energy-saving awareness, network equipment is required both performance and energy-saving. To meet this need, a low power consumption private network gateway is designed. The hardware uses a private network module supporting 1.4/1.8 GHz and 700 MHz band access, and a fifth generation Wi-Fi module. An energy management algorithm based on the state transition graph is presented in the software, which can turn off the private network communication module when no terminal is connected to Wi-Fi. The test results indicate that the performance of the gateway is close to the limit of 4 G design, and the proposed algorithm can save up to 20.75% energy. Then the comprehensive working condition of the device is built. The calculation results show that the more uplink transmission, the higher the energy-saving efficiency of the algorithm.
