摘　　要：针对快递业务中的运输安全问题,设计一种贵重包裹运输状态智能监测装置,给出装置的整体设计方案及系统软硬件详细设计方法。在硬件设计上,装置以STM32F103为主控制器,采用低功耗三轴加速度传感器ADXL345检测包裹的跌落强度,采用GPRS模块定位包裹跌落时的位置信息并发送到手机终端,采用Flash存储器存储跌落信息。在软件设计上,通过STM32嵌入式软件采集三轴加速度传感器信息,计算跌落强度,存储并发送跌落信息,并可在手机端进行查询。整个系统体积小、功耗低,实际应用效果良好。Aiming at the safety problem in express delivery business,an intelligent monitoring device for precious parcel transportation status is designed,and the overall design scheme of the device and the detailed design method of system hardware and software are given.The STM32F103 is used as the main controller,low-power 3-axis acceleration sensor ADXL345 is used to detect the dropping strength of the package,the GPRS module is used to locate the position information of the package when it falls and sends it to the mobile terminal,and the FLASH memory is used to store the drop information.The STM32 embedded software is used to collect the information of the 3-axis acceleration sensor,calculate the dropping strength,store and send the dropping information.Finally,the mobile terminal software displays the dropping information in the form of text and visualization.The whole system has small size,low power consumption and good practical application effect.
