目的 设计一种能实时监测物品贮运过程中的温度、湿度、加速度等3个参数并进行数据采集存储，同时能记录时间的具有高可靠性的贮运环境监测系统。方法 通过有限元分析软件Ansys对壳体及电路板分别进行有限元抗冲击仿真。结果 由壳体在冲击作用下的最大变形为0.03 mm及25.5 MPa的Von Miss等效应力证明壳体具有抗冲击可靠性，对电路板进行模态分析的结果证明，电路在环境冲击作用下能够可靠工作。结论 设计的贮运环境监测系统具有良好的可靠性。

This work aims to design an environmental monitoring system with high reliability that can monitor real-time temperature, humidity, acceleration in the storage and transportation process, collect data and record time. Finite element impact simulation was conducted on the circuit and shell by finite element analysis software Ansys. The maximum deformation of the shell was 0.03 mm and the Von Miss equivalent stress was 25.5 MPa under the impact effect. That proved the shell had shock resistance reliability. The results of PCB modal analysis proved that the circuit board could reliably work under the environmental impact. In conclusion, the designed environment monitoring system in storage and transportation has good reliability.
