【摘要】：随着零售业的发展,传统的商品管理方法日渐漏出弊端。采用传统纸质价签标示价格的方式,不仅让变更价格的工作变得繁重复杂,而且独立更换价签的工作流程,使得系统内价格不同步,给门店造成“价格欺诈”等不良影响。基于此背景,本文设计了一种基于无线网络的电子标价系统。本系统主要由无线通信模块、手持终端、上位机管理平台三部分组成。无线通信模块采用ZigBee无线通信技术,实现节点大范围自由布局,完成系统内数据传输,显示节点采用电子纸显示器实现低功耗运行;手持终端实现商品与显示节点绑定,完成信息上报、记录查询等操作;上位机管理平台实现商品管理、节点管理以及批量更改价格等功能。系统设计主要包括硬件设计和软件设计两部分。硬件设计包括三部分,其一是ZigBee无线通信模块的电路设计,其二为显示模块接口电路以及电源电路的设计,其三是手持终端硬件电路的设计,包括核心板、底板以及条码扫描模块。软件设计主要包括ZigBee无线网络设计、手持终端嵌入式软件设计、上位机管理平台三部分。ZigBee无线网络设计包括网络的建立、显示驱动程序的设计和通信协议的制定;手持终端嵌入式软件设计主要包括搭建Linux操作系统,设计开发手持终端应用程序;上位机管理平台的设计包括搭建商品管理系统数据库,应用Qt开发平台设计应用软件界面实现商品统一管理。本文最后对系统进行了测试,结果表明ZigBee网络通信以及显示节点功耗均满足系统需求,手持终端联合上位机管理平台实现了对商品的有效管理。
[Abstract]:With the development of retail industry, the traditional method of commodity management gradually leaks out the drawbacks. Using the traditional paper price tag to mark the price, not only makes the change of the price work more complicated, but also changes the work flow of the price tag independently, making the price in the system unsynchronized and causing the "price fraud" to the store. In this paper, an electronic pricing system based on wireless network is designed. This system is composed of three parts: wireless communication module, handheld terminal, and upper computer management platform. The wireless communication module uses ZigBee wireless communication technology to realize the free layout of the nodes in a large range, complete the data transmission in the system, and the display node adopts electronic paper display. The implementation of low power operation; the handheld terminal to bind the goods to the display nodes, complete the information report, record the query and other operations; the upper computer management platform implements the functions of commodity management, node management and batch change of price. The system design mainly includes two parts of hardware design and software design. The hardware design includes three parts, one is ZigBee The circuit design of the wireless communication module, the second is the display module interface circuit and the design of the power circuit, and the third is the design of the hardware circuit of the handheld terminal, including the core board, the bottom plate and the bar code scanning module. The software design mainly includes the ZigBee wireless network design, the handheld terminal embedded software design, and the upper computer management platform three parts. The design of ZigBee wireless network includes the establishment of network, the design of display driver and the formulation of communication protocol; the design of embedded software for handheld terminal mainly includes building the Linux operating system, designing and developing the handheld terminal application; the design of the management platform of the upper computer includes building the database of the commodity management system and applying the Qt development platform. The system is tested at the end of this paper. The results show that the ZigBee network communication and the power consumption of the display nodes meet the requirements of the system, and the handheld terminal combined with the upper computer management platform has realized the effective management of the goods.
