本实用新型的优点及积极效果为：Advantage and positive effect of the utility model are:
本实用新型模块化设计的硬件模块：整个硬件平台得每个功能模块独立设计，区别于市场上的全部整个在一块PCB板上面，可让学生清晰的明白每个模块的功能，且便于学生循序渐进的学习。The modular design of the hardware module of the utility model: the whole hardware platform has each functional module independently designed, which is different from the whole on one PCB board in the market, so that students can clearly understand the function of each module, and it is convenient for students to develop step by step study.
丰富的硬件处理器：平台中的传感网终端节点使用的MCU是8051内核，网关使用Arm公司的Cortex m3架构，嵌入式开发板使用的CPU是Cortex A8的架构。这样的硬件选型设计使得学生能从大学最基础的单片机80C51入手，然后到当下流行的实时处理器，再到熟悉的应用在智能手机中的ARM内核的CPU。配套相应的实验能够让学生逐步的从书本到实际理解计算机组成原来的知识。Rich hardware processors: The MCU used by the sensor network terminal node in the platform is the 8051 core, the gateway uses the Cortex m3 architecture of Arm Company, and the CPU used by the embedded development board is the Cortex A8 architecture. This kind of hardware selection design enables students to start from the most basic single-chip microcomputer 80C51 in the university, then to the popular real-time processor, and then to the familiar ARM core CPU used in smart phones. Supporting corresponding experiments can enable students to gradually understand the original knowledge of computer composition from books to practice.
丰富的操作系统：在物联网行业，大的控制设备，小的“微尘”设备，都需要通过操作系统来支撑，操作系统掌握的好坏决定了一个项目成功与否。因此该平台从传感网、网关、嵌入式开发板，根据不同的用途，选取了当下最流行、最易开发的操作系统；并且为不同平台所使用的操作系统移植的所有源代码全部开源，方便学生学习参考。主要包括Z-stack、contiki、linux、RT-thread。Rich operating system: In the Internet of Things industry, large control equipment and small "dust" equipment need to be supported by the operating system. The quality of the operating system determines the success of a project. Therefore, the platform selects the most popular and easiest-to-develop operating system from sensor networks, gateways, and embedded development boards according to different purposes; and all source codes transplanted for operating systems used by different platforms are all open source. It is convenient for students to study and refer to. Mainly including Z-stack, contiki, linux, RT-thread.
支持多种无线传感网传输协议：该平台使用TI公司的CC2530芯片作为传感网终端节点，因此也使用Z-stack协议栈，此协议栈标准是ZigBee，其编译平台为IAR，且在windows下操作，使用上较为简单，可作为学生初步学习传感网基础教学。同时该平台考虑到未来物联网快速的发展节奏，无线传感网设备会越多越多，引进了国外基于6lowpan的开源操作系统contiki。该操作系统实现了6lowpan，即低功耗的IPV6通讯。Z-stack是在windows环境下使用IAR开发，上手容易，能够初步的感受传感网的概念。而contiki是在linux下开发，有了Z-stack的基础，学习contiki只是强化linux下操作，对未来学习嵌入式开发板打下深厚基础。通过这种多系统的学习比较模式能够达到“授之与渔”的目的，引导学生“学会学习”，这才该平台真正目的。Support a variety of wireless sensor network transmission protocols: The platform uses TI's CC2530 chip as the sensor network terminal node, so it also uses the Z-stack protocol stack.

Through this multi-system learning comparison mode, the purpose of "teaching and fishing" can be achieved, and students can be guided to "learn to learn", which is the real purpose of the platform.
引入低功耗IPV6：在未来物联网“微尘”会越来越多，节点会无限制的往上涨，这个时候IPV6就能体现出其本身的IP自动配置、128位的宽范围IP地址的优势。Introduce low-power IPV6: In the future, there will be more and more "dust" in the Internet of Things, and the number of nodes will increase without limit. At this time, IPV6 can reflect its own IP automatic configuration and 128-bit wide-range IP address. Advantage.

RFID部分RFID part
表2 RFID应用介绍Table 2 RFID application introduction
RFID是物联网一个核心部件，该平台支持三种不同的标准，主要从高频和超高频的识别距离、标准特性来讲解。在现在的公交卡、食堂卡、热水卡等IC卡中，都是用的高频卡，大部分属于14443的标准；而在车辆管理、资产管理、仓储管理、货物流通管理中大都使用超高频，超高频具有识别距离远、能够多标签识别的优势。RFID标签与一维码、二维码最大的区别就是其能够多次的擦除和写入。在实验中能够通过验证性的实验验证各个RFID的特性，让学生直观的了解到RFID的标准特性。以下通过18000-6C为例介绍RFID部分。RFID is a core component of the Internet of Things. The platform supports three different standards, mainly explained from the recognition distance and standard characteristics of high frequency and ultra high frequency. In the current IC cards such as bus cards, cafeteria cards, and hot water cards, high-frequency cards are used, and most of them belong to the 14443 standard; most of them use ultra-high-frequency cards in vehicle management, asset management, warehouse management, and cargo circulation management. High frequency, UHF has the advantages of long recognition distance and multi-tag recognition. The biggest difference between RFID tags and one-dimensional codes and two-dimensional codes is that they can be erased and written multiple times. In the experiment, the characteristics of each RFID can be verified through confirmatory experiments, so that students can intuitively understand the standard characteristics of RFID. The following uses 18000-6C as an example to introduce the RFID part.
本系统内配套的超高频读写模块，其符合ISO18000-6C标准。可通过USB链接与电脑相连接，或者使用蓝牙与手机进行链接。The supporting UHF read-write module in this system complies with the ISO18000-6C standard. It can be connected to a computer via a USB link, or to a mobile phone using Bluetooth.
通过USB链接电脑后，可在PC端进行功率、频率、灵敏度等参数进行设置。并可在线扫卡，扫描到的标签信息能够实时的显示在客户端；并且能通过界面对标签进行数据读取、写入、擦除、锁死、杀死等RFID标准操作。After connecting to the computer via USB, parameters such as power, frequency, and sensitivity can be set on the PC. And it can scan the card online, and the scanned tag information can be displayed on the client in real time; and can perform data reading, writing, erasing, locking, killing and other RFID standard operations on the tag through the interface.
APP程序中，该程序可通过蓝牙与RFID读写器相连读取读写器采集的数据。学生能够通过阅读API调用说明编写更多应用软件，比如人员考勤管理、车辆门禁管理、资产管理等软件，这样使学生能够实际的掌握RFID标签的实际操作步骤和使用原理。In the APP program, the program can be connected to the RFID reader through Bluetooth to read the data collected by the reader. Students can write more application software by reading API call instructions, such as personnel attendance management, vehicle access control management, asset management and other software, so that students can actually master the actual operation steps and usage principles of RFID tags.
在现在的资产管理中，都会使用到手持终端，因此我们在读写器内部添加了蓝牙模块，智能手机可通过蓝牙模块与读写器进行通信。因此学生可开发相应的App来实现PC端的功能。In the current asset management, handheld terminals are used, so we add a Bluetooth module inside the reader, and the smart phone can communicate with the reader through the Bluetooth module. Therefore, students can develop corresponding apps to realize the functions of the PC side.
使用蓝牙链接此RFID读写器的资产管理App，学生能够通过这个App的演示学习怎么将读写器和智能应用相互关联，激发学生了解RFID在实际生活中的应用场景。Using Bluetooth to link the asset management app of this RFID reader, students can learn how to connect the reader and smart applications through the demonstration of this app, and inspire students to understand the application scenarios of RFID in real life.
