摘　　要：目前5G节能业界常见的做法是加装节能控制单元,通过物联网手段远程控制AAU/RRU的开关,达到节电目的。研究利用基站自身提供的输出干接点信号,通过简单的电路改造,控制干接点状态翻转,实现对AAU/RRU以及机房空调开关的通断控制,达到节电目的。这种节能方式无需加装外购设备,对于控制信号的传输完全是内部通道,规避了控制信号通过空口传递存在的安全隐患。同时,配合准实时的节能策略,使得节能操作对于用户的感知的影响降到了最低。In the 5G power-saving domain,the prevalent approach involves installing energy control units to remotely manage AAU/RRU switches via Io T,aiming to conserve power.This study capitalizes on the dry contact signal output provided by the base stations themselves.With straightforward circuitry modifications,the dry contact state is manipulated to govern the connectivity of both the AAU/RRU and data center air conditioning systems,thus achieving the goal of power conservation.This power-saving method obviates the need for externally purchased equipment,relying solely on internal channels for control signal transmission,thereby circumventing the security vulnerability of over-the-air signal transmissions.Concurrently,when integrated with near real-time power-saving policies,the perceptible impact on users due to power-saving actions is substantially reduced.
