【摘要】：物联网(IOT)技术已大量应用于诸如交通、物流、工业控制等现代化社会的众多领域。得益于其广大的应用前景,物联网技术发展迅猛。与此同时,被公认为物联网核心技术之首的射频识别技术(RFID)技术,随着物联网的快速发展,也迅速发展成为一项世界各国最为关注的信息技术。现阶段,从国内来看,低频与高频频段FRID技术发展相对成熟,并且以其广泛的应用场景逐渐占据了RFID的主流市场。超高频频段RFID与前两者相比具有多方面的优势,如更远的读写距离、更快的读写速度、更优的标签防碰撞性能等,这为其创造了更广阔的发展空间,目前已逐渐在智能交通、智慧医疗、供应链管理等众多领域展开了应用。但总体上讲,超高频频段RFID技术的研究与应用目前还相对滞后,到形成一条完整的产业链还有很长一段路要走。目前市面上已经出现了一些具有超高频RFID识别功能的物联网终端产品,但大多功能单一还不能完全满足当前的市场应用需求。在此背景下,设计一款具备超高频RFID、条码识别和温湿度传感器信息采集等功能的手持式物联网终端,具有实际的科研与经济意义。首先,本文首先对物联网的基本概念及其系统架构进行了简要的介绍,分析物联网技术发展现状与前景,对手持式物联网终端的具体应用模式进行了描述,并分析了本课题选题意义以及本文所涉及的工作与内容组织。其次,完成本文课题项目技术指标分析,在此基础上对手持式物联网终端进行了系统架构的设计,涉及系统硬件、软件架构以及终端平台操作系统选型等。再次,详细介绍了Windows CE操作系统的移植与开发,包括系统启动代码的移植开发以及与系统BSP密切相关的功能开发等。然后,介绍了条码识别单元、传感器单元、UHF RFID单元的驱动和上层应用程序设计与实现。根据实际应用求,实现了三大功能融合为一体的综合应用程序及PC上位机数据处理程序。最后,建立系统测试平台对各软硬件功能部分进行测试,总结已完成工作展望未来。
[Abstract]:IOT (Internet of things) technology has been widely used in many fields of modern society, such as transportation, logistics, industrial control and so on. With the rapid development of the Internet of things, RFID (Radio Frequency Identification) technology, which is recognized as the first of the core technologies of the Internet of things, has also rapidly developed into an information technology most concerned by all countries in the world. At this stage, from the domestic point of view, The FRID technology of low frequency and high frequency band is relatively mature, and it has gradually occupied the mainstream market of RFID with its extensive application scene. Compared with the former two, UHF band RFID has many advantages, such as far distance between reading and writing. Faster reading and writing speed, better label anti-collision performance and so on, which have created a wider space for its development, and have been gradually applied in many fields, such as intelligent transportation, smart medical treatment, supply chain management, etc. But generally speaking, it has been used in many fields, such as intelligent transportation, intelligent medical treatment, supply chain management and so on. The research and application of UHF RFID technology is still lagging behind, and there is still a long way to go to form a complete industrial chain. At present, there are some Internet of things terminal products with UHF RFID recognition function on the market. However, most of the single functions can not fully meet the needs of current market applications. Under this background, a hand-held Internet of things terminal with the functions of ultra-high frequency RFID, bar code recognition and temperature and humidity sensor information collection is designed. It has practical scientific research and economic significance. First of all, this paper briefly introduces the basic concept and system structure of the Internet of things, and analyzes the present situation and prospect of the development of the Internet of things technology. This paper describes the specific application mode of the hand-held Internet of things terminal, and analyzes the significance of the topic and the work and content organization involved in this paper. Secondly, the technical index analysis of the project is completed. On this basis, the system architecture of hand-held Internet of things terminal is designed, including system hardware, software architecture and terminal platform operating system selection. Thirdly, the transplantation and development of Windows CE operating system are introduced in detail. It includes the transplant development of the system startup code and the function development closely related to the system BSP. Then, the paper introduces the design and realization of the bar code identification unit, the driver of the sensor unit and the upper layer application program, according to the actual application, the design and implementation of the bar code identification unit, the sensor unit and the UHF RFID unit are introduced. The integrated application program and PC data processing program are realized. Finally, the system test platform is established to test the functions of software and hardware, and the finished work is summarized in the future.
