摘　　要：针对高值高危特殊产品运输监控需求,基于破损边界理论,对冲击量与冲击时间进行监测,开发了一型可定制数字式冲量检测仪。检测仪采用经测试筛选的高精度MEMS运动传感器,内置冲量曲线滤波算法,通过实验对比优于机械式冲击指示器。系统还具备低功耗、数据记录、GPS、蓝牙、4G网络功能,实现货运全程监测记录。In this paper, a customizable digital impulse Indicator is developed to monitor the impact volume and impact time based on the damage boundary theory for high-value and high-risk special cargo transportation monitoring needs. The indicator adopts tested and screened high-precision MEMS motion sensor with built-in impulse curve filtering algorithm, which is better than mechanical impact indicator by experimental comparison. The system also has low power consumption, data logging, GPS, Bluetooth and 4G network functions to realize the whole process of freight monitoring and recording.
