基于嵌入式快递包裹实时跟踪系统设计

摘要

The express parcel real⁃time tracking system is mainly composed of parcel sensor module,vehicle⁃mounted em⁃bedded terminal and customer webpage query system. S3C2440 is used as the main controller of the system to inspect the real⁃time state of packages through several sensors. The parcel sensor system communicates with the embedded system through the wireless module. The GPS receiver is used to receive latitude and longitude information. All of the information related to package is sent to a remote server through GPRS. In combination with Google maps,various warning marks of packages can be found by the webpage client,and at the same time,real⁃time display of the express packages’traveling trajectory is realized. The infor⁃mation feedback and real⁃time tracking functions of the express packages in their traveling process were implemented.%快递包裹实时跟踪系统主要由包裹传感器模块、车载嵌入式终端以及客户网页查询系统组成。系统以S3C2440作为主控制器，通过若干传感器检查包裹的实时状态。包裹传感器系统与车载嵌入式系统通过无线模块进行通信，用GPS接收器接收经纬度信息，所有包裹相关信息以GPRS无线传输到远程服务器；网页客户端结合Google地图将包裹发生的各种警报标记在地图上，同时在地图上实现包裹运行轨迹的实时显示；最终解决了传统快递所不具备的包裹实时跟踪轨迹和快递运输过程中信息反馈功能的问题。
