摘　　要：母线槽信号包含大量平稳信号和部分突发情况信号,完整准确地采集其信号能够保证母线槽的稳定运行。保持高上传率可准确地采集到信号,但功耗过大,降低设备使用寿命。文章提出一种适用母线槽信号的无线传感器节点近似采样策略(approximate sampling method,ASM),通过分析所采数据的相对变化程度及变化趋势捕捉完整突发情况信号,水塘抽样算法剔除部分无效平稳数据,完整准确地上传母线槽状态趋势信号。通过Matlab仿真表明ASM采样策略相比于SOD(send-on-delta)、无线传感器节点动态采样策略(dynamic sampling internal,DSI),无效采样率、变化偏移量更小,降低了能耗且保证了采样信号完整。The parent line slot signal contains a large number of stable signals and some burst signals,and collects its signal to ensure the operation stable.Maintain the signal accurately,but the power consumption is too large,reducing the service life of the equipment.This article proposes a wireless sensor node that is applicable to the parent line slot signal.Node is approximately sampling strategy ASM.By analyzing the relative changes and changes of the data adopted to capture the complete emergencies signal,the pond sampling algorithm eliminates partial invalid and stable data,and uploads a complete and accurate upload.Buttaic groove state trend signal.Through the Matlab simulation,the AMS sampling strategy compared to SOD(send-on-delta)and DSI(dynamic sampling internal)sampling strategies,the invalid sampling rate and change have smaller offset,reducing energy consumption and ensuring the complete sampling signal.
