摘　　要：针对水库大坝野外无人值守环境中的低成本表面变形监测场景,该文基于微机电系统(MEMS)惯性传感器建立了从传感到云端的监测系统,面向应用场景中的实际需求,基于星形自组网网络拓扑设计了高可靠冗余通信链路。针对长时无人值守的表面变形监测需求,从传感、供能和通信等方面进行了工程设计。面向应用场景中的恶劣环境(如雨、雪、暴晒、高温、高寒等),设计了防水等级达IP68的外壳防护结构。环境试验和现场测试表明,该文设计的基于MEMS惯性传感器的变形监测系统具有稳定、精确的表面变形监测指标,以及可靠、高频的数据通信能力。Aiming at the low-cost surface deformation monitoring scenario in the field unattended environment of reservoir dams,this paper establishes a monitoring system from sensing to cloud based on MEMS inertial sensors.Facing the actual needs of the application scenario,we design a highly reliable and redundant communication link based on the star ad hoc network topology.Aiming at the long-term unattended surface deformation monitoring requirements,engineering design was carried out from three aspects:sensing,energy supply and communication.Facing the harsh environment such as rain,snow,exposure,high temperature and cold in the application scenario,the shell protection structure with a waterproof level of IP68 is designed.Environmental tests and field tests show that the deformation monitoring system based on MEMS inertial sensor designed in this system has stable and accurate surface deformation monitoring indicators,reliable and high-frequency data communication capabilities.
