【摘要】：电子商务促进了物流仓储、运输等相关产业的发展。基于线上-线下平台的外卖点餐、衣物送洗等服务也需要物流配送的支撑。由于客户与配送员时间和空间难以匹配,也就是物流运输的交货的"最后一公里"问题,使得末端配送的效率一直得不到提升。本论文旨在设计一款低功耗的网络控制收发系统,将低效的、需要商定时间窗口与等待地点的传统人对人物流投递、接收变为简洁高效的人与机器间的互动,提高配送效率,减少不必要的配送等待时间,从而解决配送人员与收件人员时空匹配度差的问题,让社会资源配置达到最大化。系统设计过程中的主要研究内容包括:1.深入分析网络控制收发系统的需求,设计了系统工作流程和软硬件方案。2.根据系统方案完成元器件选型,选择MSP430为箱体控制核心,Si4432为箱体与网关通信的射频芯片,完成低功耗电路设计。3.移植并改进了嵌入式操作系统μC/OS-II,降低了操作系统运行功耗,压缩了射频Soc模块的唤醒时间,借鉴DPM的思想设计了系统低功耗工作方式。4.采用SSI框架搭建系统服务端,与网关通过WebSocket技术实时通信,完成系统性能测试与功耗实验。经过实验测试,系统能够保证必要的性能同时保持极低的功耗,采用三节干电池供电,可工作800天左右。
[Abstract]:E-commerce promotes the development of logistics warehousing, transportation and other related industries. On-line-off-line platform-based take-out, laundry and other services also need logistics support. Due to the difficulty of matching time and space between customer and distributor, that is, the "last kilometer" of delivery of logistics transportation, the efficiency of terminal distribution has not been improved. The purpose of this paper is to design a low-power network control transceiver system, which can deliver the traditional man-to-human logistics system with low efficiency and need to agree on the time window and waiting place, and the reception becomes a simple and efficient interaction between human and machine, which can improve the efficiency of distribution. To reduce the unnecessary waiting time of distribution, so as to solve the problem of poor space-time matching between the distribution personnel and the recipient, and to maximize the allocation of social resources. The main research contents in the system design process include: 1. The requirement of the network control transceiver system is analyzed deeply, and the system workflow and the software and hardware scheme are designed. According to the system scheme, MSP430 is selected as the core of box control, Si4432 is used as RF chip for communication between box and gateway, and low power consumption circuit is designed. 3. The embedded operating system 渭 C / OS-IIwas transplanted and improved, which reduced the operating power consumption, compressed the wake-up time of the RF Soc module, and designed the low power working mode of the system by using the idea of DPM. The SSI framework is used to build the system server and communicate with the gateway through WebSocket technology. The system performance test and power consumption experiment are completed. The experimental results show that the system can ensure the necessary performance while maintaining extremely low power consumption. The system can work for about 800 days with three dry batteries.
