摘　　要：微机械传感器即MEMS传感器的体积非常小,同区域环境中干扰较多,且传感节点多跳传输路径是堆积的,导致传感节点能耗的控制存在较大难度。为保障微机械传感系统的运行稳定性,研究了一种新的微机械传感节点能耗控制方法。构建多跳传输方式下的微机械传感节点能耗影响因素分析模型。采用加权分簇法完成传感节点分簇、分组、深度控制和优化循环等。以能耗总和测试、生命周期运行轮数为指标,仿真分析研究方法的性能。仿真分析结果表明,随着仿真迭代次数的增加,采用所提方法的传感节点能耗总和上升速度较慢,同时总能耗也为最低,所提方法下传感节点生命周期运行轮数最高可达4600轮,以上仿真分析结果验证了所提方法的可靠性较强。Micromechanical sensors,namely MEMS sensors,have very small volumes,there are more interferences in the same area environment,and the multi-hop transmission paths of sensor nodes are stacked,resulting in great difficulty in energy consumption control of sensor nodes.In order to ensure the stability of micromechanical sensor system,a new energy consumption control method of micromechanical sensor node is studied.An analysis model of energy consumption influencing factors of micro-mechanical sensor nodes in multi-hop transmission mode is established.The weighted clustering method is used to accomplish the clustering,grouping,depth control and optimization cycle of sensor nodes.The performance of the method is simulated and analyzed with the total energy consumption test and the number of life cycle running rounds as indicators.The simulation analysis results show that with the increase of the sensor nodes with the number of simulation iterations,the total energy consumption of the sensor nodes with the proposed method increases slowly,and the total energy consumption is also the lowest.The maximum number of life cycle running rounds of the proposed method can reach 4600 rounds.The simulation analysis results above verify the reliability of the proposed method.
