【摘要】：随着电子领域的迅速发展,电子收款机越来越广泛的应用于我们的生活中,与人们生产生活密切相关。电子收款机属于消费类电子产品,主要功能是帮助销售人员进行销售、管理人员进行管理。可以为营业减少差错,提供高质量的服务改善经营环境。电子收款机广泛应用在超市、饭店、宾馆、加油站、等消费类行业,可以精确的记载收银人员每笔业务,记录的同时统计收款员的营业业绩,杜绝恶意作弊弄虚作假现象,保护经营者的经济权益。本文对嵌入式电子收款机的功能、硬件系统以及软件系统进行深入的分析与论证,首先论述了收款机实用价值以及研究意义;其次是根据生活中的观察,设计出理想的电子收款机的功能。最后根据LPC2214芯片组进行设计、分析论证,进行硬件设计。硬件设计包括原理图的设计、硬件电路的PCB设计、元器件的库文件设计、硬件模块打印机的通信设计、硬件模块显示电路的调试、存储电路的调试、硬件电路电源系统的设计、硬件电路电磁兼容的分析;软件设计包括软件系统的总体设计、操作系统的任务分配,软件系统的任务设计、软件系统的模块设计,各个模块之间的通信流程;软件系统和硬件系统的调试过程;软件系统控制硬件系统的过程等等。电子收款机可以按时统计出商品的总销售量、营业额、客流量、单类商品的销售量、单类商品的销售额以至商品库存量等营业数据,方便经营者时时监控商品销售情况。项目开发设计最终结果表明,嵌入式电子收款机可以完成复杂的销售任务,提供可靠安全的销售活动。实现对人、财、物等业务工作的综合管理。本文在第一章讨论电子收款机的设计价值、设计理念、在消费类电子产业中的地位;第二章根据实际需要分析并讨论电子收款机的设计功能,提出一个设计的理念;第三章讨论电子收款机的硬件电路部分,根据硬件电路进行设计收款机第四章讨论电子收款机的软件系统部分,根据收款机的功能设计软件系统;第五章进行电子收款机总结,对收款机在软件系统和硬件系统在设计过程中的不足和改进加以讨论。经最后的测试电子收款机,表明收款机各项指标均达到要求。
[Abstract]:With the rapid development of electronic field, electronic cash registers are more and more widely used in our life, closely related to people's production and life. Electronic cash registers are consumer electronic products, the main function is to help sales personnel. Management personnel. Can reduce business errors, provide high-quality services to improve the business environment. Electronic cash registers are widely used in supermarkets, restaurants, guesthouses, gas stations, and other consumer industries, It can accurately record every business of the cashier, record the business performance of the cashier at the same time, put an end to the phenomenon of malicious cheating and fraud, protect the economic rights and interests of the operator. The hardware system and software system are deeply analyzed and demonstrated. Firstly, the practical value and research significance of cash register are discussed; secondly, according to the observation in life, Finally, according to LPC2214 chipset design, analysis and demonstration, hardware design. Hardware design includes schematic design, hardware circuit PCB design, components library file design. Hardware module printer communication design, hardware module display circuit debugging, storage circuit debugging, hardware circuit power supply system design, hardware circuit electromagnetic compatibility analysis. Task assignment of operating system, task design of software system, module design of software system, communication flow between each module, debugging process of software system and hardware system; The software system controls the process of the hardware system and so on. The electronic cash register can calculate on time the total sales volume, turnover, passenger flow, sales volume of single goods, sales volume of single goods, and the stock of goods, etc. The final results of the project development and design show that embedded electronic cash registers can complete complex sales tasks and provide reliable and secure sales activities. The first chapter discusses the design value of electronic cash register, the design concept, the position in the consumer electronics industry, the second chapter analyzes and discusses the design function of electronic cash register according to the actual needs. The third chapter discusses the hardware circuit of the electronic cash register, the fourth chapter discusses the software system of the electronic cash register according to the hardware circuit, and the software system is designed according to the function of the cash register. Chapter five summarizes the electronic cash register and discusses the deficiency and improvement of the cash register in the design process of the software system and the hardware system. After testing the electronic cash register at last, it shows that each index of the cash register meets the requirements.
