【摘要】：储物柜被广泛应用于公共场所。传统的储物柜在安全性、便利性以及方便管理方面都有很多值得改进的地方。随着电子技术的发展,电子储物柜开始进入人们的视野。最常用于大型超市等场所的电子储物柜一般采用条形码作为开锁的钥匙。这在安全性上存在缺陷,同时也不环保。此外系统中并没有记录数据来保证物品不会被冒领。安全性更高的指纹识别型储物柜成本太高,可预见的未来很难大规模推广。新型储物柜的革新始于物流领域,为了降低最后一公里的运输成本,国内外许多公司投资研发更安全方便的储物柜。 互联网技术的发展以及物联网概念的提出为我们设计新型储物柜提供了思路。传统储物柜安全隐患主要在于开锁的钥匙容易被复制,并且存包的记录也没有存入系统,事后无法查证。而借助于物联网,可以将储物柜接入网络,管理员对每个柜子的状态将了如指掌,不仅方便管理还提高了安全性。 对于不同应用场景,新型储物柜设计所要考虑的因素不同,方案会千差万别。对于物流公司使用的置于室外的储物柜要侧重考虑柜子的坚固性等。本文是以学校图书馆为应用场景。图书馆是学校重要的学习场所,人流量大,学生有存包的需求。使用传统的储物柜经常会发生失窃事件,此外图书馆安装的储物柜有限,资源有限。 为响应国家关于高校信息化建设的号召,本文结合物联网技术、RFID技术以及嵌入式技术设计了一套安全、便捷的适用于校园的储物柜系统。目前这一系统已在山东大学各图书馆投入使用。本系统最大的特点在于安全、使用便捷以及方便管理。由于校园一卡通已经在学校中广泛使用,使用一卡通作为钥匙是最自然的选择。因此储物柜配备了射频卡读写器。为了增加安全性,系统加入了密码验证模块。每张卡片都设有密码,用户输入密码,服务器验证通过后方能开锁。这样,即使在卡片丢失后也无须担心物品被盗。本系统在每个柜子中安装了红外传感器用来检测是否存放物品,每个柜子的状态都实时传到服务器中。用户可以通过管理网站来预约储物柜,管理员可以远程控制每个柜子。储物柜的状态被实时感知,这也提高了柜子的利用率。 本文主要从硬件和软件两个方面对物联网储物柜系统的设计进行详细介绍。硬件部分主要包括终端的储物柜控制器模块、RFID读写器模块以及嵌入式网关模块。控制器模块负责执行服务器端的命令并检测储物柜的状态。RFID读写器模块负责读取校园一卡通。嵌入式网关负责上层与下层通信协议的转换。软件部分主要包括控制器模块程序、嵌入式网关程序以及上层管理网站程序。
[Abstract]:Lockers are widely used in public places. There are many things worth improving in traditional lockers in terms of safety, convenience and convenient management. With the development of electronic technology, electronic lockers began to enter people's field of vision. The electronic lockers most commonly used in large supermarkets and other places usually use bar code as the key to unlock. This is flawed in safety and is not environmentally friendly. In addition, no data are recorded in the system to ensure that items are not falsely obtained. The cost of fingerprint recognition lockers with higher security is too high, so it is difficult to popularize them on a large scale in the foreseeable future. The innovation of the new lockers begins in the field of logistics. In order to reduce the transportation cost of the last kilometer, many companies at home and abroad invest in the development of safer and more convenient lockers. The development of Internet technology and the concept of Internet of things provide us with ideas for the design of new lockers. The security hidden danger of traditional lockers is that the key to unlock is easy to be copied, and the records of storing bags are not stored in the system, which can not be verified afterwards. With the help of the Internet of things, the lockers can be connected to the network, and the administrator will know the state of each cabinet like the palm of his hand, which not only facilitates the management but also improves the security. For different application scenarios, the factors to be considered in the design of the new lockers will be very different. For logistics companies to use outdoor lockers to focus on the firmness of cabinets and so on. This paper takes the school library as the application scene. The library is an important learning place in the school, with a large flow of people and the need for students to keep bags. Theft often occurs when traditional lockers are used. In addition, the lockers installed in the library are limited and the resources are limited. In order to respond to the national call on the information construction of colleges and universities, this paper designs a set of safe and convenient lockers system suitable for campus by means of network technology, RFID technology and embedded technology. At present, this system has been put into use in the libraries of Shandong University. The biggest characteristic of this system is security, convenient use and convenient management. Because campus card has been widely used in school, the use of one card as the key is the most natural choice. Therefore, the lockers are equipped with RF card readers. In order to increase security, the system adds password verification module. Each card has a password, the user enters the password, and the server can unlock it only after it has passed. In this way, even after the card is lost, there is no need to worry about the theft of items. In this system, infrared sensors are installed in each cabinet to detect whether or not to store items, and the status of each cabinet is transmitted to the server in real time. Users can book lockers by managing websites, and administrators can remotely control each cabinet. The state of lockers is perceived in real time, which also improves the utilization rate of lockers. In this paper, the design of Internet of things lockers system is introduced in detail from two aspects of hardware and software. The hardware part mainly includes the terminal lockers controller module, RFID reader module and embedded gateway module. The controller module is responsible for executing server-side commands and detecting the status of lockers. RFID reader module is responsible for reading campus card. The embedded gateway is responsible for the conversion of communication protocols between the upper layer and the lower layer. The software part mainly includes controller module program, embedded gateway program and upper management website program.
