基于睡眠算法的卫星终端低功耗设计

Low power design of satellite terminal based on sleep algorithm

从待机低功耗考虑,分析终端的主要耗电模块,结合GMR-13G卫星通信协议,研究终端的空闲模式特性及其工作模式。利用非连续接收的思想,提出针对终端在空闲模式下信道数据接收的睡眠算法,通过睡眠算法,实现终端功能模块在具体帧号的打开或关闭。将低功耗模式划分为浅睡模式及深睡模式,基于睡眠算法对这两种模式分别进行设计。通过对功耗数据进行测试,验证了低功耗设计方案能够有效降低终端空闲状态下的待机功耗。

Considering the low power consumption in standby mode,the main power consumption modules of the terminal were analyzed,and the GMR-13G satellite communication protocol was combined,the idle mode characteristics and working mode of the terminal were studied.Based on the idea of discontinuous reception,a sleep algorithm for the channel data reception of the terminal in idle mode was proposed.Through the sleep algorithm,the function module of terminal was turned on or off at speci-fic frame number.The low-power mode was divided into light sleep mode and deep sleep mode,and these two modes were designed separately based on the sleep algorithm.By testing the power consumption data,it is verified that the low-power design scheme can effectively reduce the standby power consumption of the terminal in idle mode.
