【摘要】：随着我国经济的飞速发展,商场中的价签得到大家的广泛关注。在日常生活中,价签随处可见,它为消费者提供商品的名称、产地和价格等信息,更加方便消费者购买。但是传统的纸质价签在生产和使用的过程中容易受到生产条件和外界环境等因素的影响,由于价签所显示信息与商品实际信息不匹配而带来的问题,不仅为消费者带来麻烦,甚至会造成商家与消费者之间的纠纷。针对这个问题,提出了基于物联网的电子价签管理系统,保证价签信息实时准确,实现对价签显示信息和工作状态的全面管理。作为国家863项目“基于物联网的工业管控一体化项目”的一部分,本系统通过分析电子价签的国内外发展现状,结合物联网的相关技术,设计并实现一套完整的电子价签管理系统。本系统的主要工作如下：(1)针对传统价签存在的易丢失、更新慢等问题,不再采用传统纸制品和液晶屏作为显示设备,而是采用电子纸显示器,此显示器具有易阅读、低功耗和无需持续刷新等优点；(2)价签的显示终端定时向汇聚节点发送心跳包,汇聚节点将心跳包信息存放在数据库中,管理系统通过对心跳包信息的检查,来实现对价签显示终端的工作状态进行实时的管理；(3)利用B/S模式搭建电子价签的管理系统,能够对所有价签进行创建、查找、删除等操作,同时能够实现价签信息的导出和打印；(4)对数据库中的信息、操作界面显示的信息和显示设备上的信息保证同步更新；(5)通过Socket异步通信技术,完成价签显示终端和管理系统的实时通信,使得指令的发送和反馈信息的接收能够同时进行,保证整个系统的通信正常,以实现对电子价签实时的、全面的管理。本系统结合了物联网中的无线传输、Socket通信等技术,选用低能耗、高性能的硬件设备。经测试表明,本系统运行状态稳定,节点之间可以进行一定距离的信息传输,价签显示终端可以与管理系统进行及时的信息交互。同时,系统具有功耗低、成本低、体积小、设备安装使用方便、可扩展,抗干扰能力强,应用范围广等特点,实现对电子价签的有效管理。
[Abstract]:With the rapid development of economy in our country, the price tag in shopping malls has been paid more and more attention. In daily life, the price tag can be seen everywhere, it provides consumers with information about the name, origin and price of the goods, which is more convenient for consumers to buy. However, the traditional paper price tag is easy to be affected by the production conditions and the external environment in the process of production and use. The problems caused by the mismatch between the information displayed by the price tag and the actual information of the commodity not only bring trouble to the consumers. It can even cause disputes between merchants and consumers. To solve this problem, an electronic price tag management system based on the Internet of things is proposed to ensure the real-time accuracy of the price tag information and to realize the overall management of the price tag display information and the working state. As part of the national 863 project "Industrial Management and Control Integration Project based on the Internet of things", this system combines the relevant technologies of the Internet of things by analyzing the domestic and foreign development status of electronic price tag. Design and implement a complete set of electronic price tag management system. The main work of this system is as follows: (1) aiming at the problems of loss and slow updating of traditional price tags, traditional paper products and LCD screens are no longer used as display devices, but electronic paper displays, which are easy to read. A display terminal with low power consumption and no need for continuous refresh sends a heartbeat packet to a sink node on a regular basis. The sink node stores the heartbeat packet information in a database, and the management system checks the heartbeat packet information. To realize the real-time management of the working state of the price tag display terminal.) to build an electronic price tag management system using the B / S model, and to create, find, delete and other operations on all the price tags. At the same time, it can realize the export and printing of the price tag information, and the information in the database, the information displayed in the operation interface and the information on the display equipment can be updated synchronously by means of socket asynchronous communication technology. The real-time communication between the price sign display terminal and the management system is completed, so that the sending of instructions and the receiving of feedback information can be carried out simultaneously, ensuring the communication of the whole system is normal, so as to realize the real-time and comprehensive management of the electronic price tag. This system combines the wireless transmission socket communication technology in the Internet of things, chooses the low energy consumption, the high performance hardware equipment. The test results show that the system is running stably, the nodes can transmit information in a certain distance, and the price tag display terminal can interact with the management system in time. At the same time, the system has the characteristics of low power consumption, low cost, small volume, convenient installation and use of equipment, extensible, strong anti-interference ability, wide application range and so on, so it can realize the effective management of electronic price tag.
