摘　　要：为实现长期无人值守的震动测量与目标识别,设计了一种超低功耗无线震动传感器。该传感器采用磁电式敏感元件来获取震动信号,通过信号调理、数据采集、数据分析、数据存储和无线通信的软硬件设计,完成目标识别和数据传输。通过免供电传感和双处理器设计实现超低功耗工作,利用无线传感器网络监测模式构建无线、分布式震动监测网络。试验结果表明:该传感器能够完成震动信号测量并识别履带车和行人这两种典型目标,电流仅有30μA,预计可连续工作200天以上。In order to achieve long-term unattended vibration measurement and target recognition,design an ultra low-power consumption wireless vibration sensor. The sensor adopts electromagnetic sensitive element to obtain vibration signal,and completes target recognition and data transmission through software and hardware design of signal conditioning,data acquisition,data analysis,data storage and wireless communication. Realize ultra-low power consumption working through free power supply sensor and dual processor design,and use WSNs monitoring mode to build wireless,distributed vibration monitoring network. Test results show that the sensor can complete vibration signal measurement and target recognition of caterpillar vehicles and pedestrians,its current is only30 μA,expected to work continuously for more than 200 days.
