【摘要】：隨著時(shí)代變遷和社會發(fā)展,以方便、快捷和自助式服務(wù)為特點(diǎn)的自動售貨機(jī)得到迅猛發(fā)展,而嵌入式技術(shù)的不斷進(jìn)步,又推動了自動售貨機(jī)逐步發(fā)展成為具有智能、自助的電子商務(wù)系統(tǒng),其實(shí)現(xiàn)基礎(chǔ)則是互聯(lián)網(wǎng)通信技術(shù)及其聯(lián)網(wǎng)管理技術(shù)。 本文首先簡要介紹自動售貨機(jī)的研究現(xiàn)狀和發(fā)展趨勢,結(jié)合客戶需求和當(dāng)前無線城市的發(fā)展特點(diǎn),針對現(xiàn)有的自動售貨機(jī)多數(shù)采用GSM或GPRS為無線通信方式,其后期維護(hù)管理成本較高的特點(diǎn),將WiFi技術(shù)首次引入自動售貨機(jī)不僅使得其具有較好的移動性,并可充分利用客戶自身網(wǎng)絡(luò)進(jìn)行個(gè)性化管理。 系統(tǒng)硬件采用主從式結(jié)構(gòu)設(shè)計(jì),使用具有多主機(jī)功能的CAN-bus總線連接主控制板和驅(qū)動控制板,并以此為基礎(chǔ)實(shí)現(xiàn)了銷售集群的概念,其中主控制板使用32位的ARM控制器,并集成MDB通信模塊和USB Host等模塊,在實(shí)現(xiàn)了基本的銷售功能基礎(chǔ)上,提供了基于U-disk或者WiFi銷售數(shù)據(jù)管理功能。 由于網(wǎng)絡(luò)通信的復(fù)雜性和自動售貨機(jī)具有模塊多、實(shí)時(shí)性要求高等特點(diǎn),采用了實(shí)時(shí)性好、驅(qū)動程序豐富的開源嵌入式可配置操作系統(tǒng)eCos,并在其驅(qū)動框架下編寫以太網(wǎng)、Flash、USB Host等相關(guān)模塊驅(qū)動程序。通過分析IEEE802.11等通信技術(shù),實(shí)現(xiàn)了有線通信和基于WiFi無線網(wǎng)卡的無線通信方式,并為中小型客戶提供采用GoAhead嵌入式WEB服務(wù)器而實(shí)現(xiàn)的遠(yuǎn)程設(shè)置、訪問能力,較使用專有軟件更加便利。終端控制系統(tǒng)的軟件設(shè)計(jì)開發(fā)均采用開源軟件,符合當(dāng)前的發(fā)展趨勢。 最后,對產(chǎn)品進(jìn)行了功能性測試和總結(jié),結(jié)果表明本設(shè)計(jì)不僅增加了產(chǎn)品網(wǎng)絡(luò)管理的便利性,而且有效提高了產(chǎn)品的經(jīng)濟(jì)效益,有助于自動售貨機(jī)的進(jìn)一步推廣。
[Abstract]:With the change of times and the development of society, vending machines characterized by convenient, fast and self-service have been developed rapidly, and the continuous progress of embedded technology has promoted the development of vending machines with intelligence. Self-help e-commerce system is based on internet communication technology and its network management technology. Firstly, this paper briefly introduces the research status and development trend of vending machines, combined with customer demand and the development characteristics of wireless cities, most of existing vending machines adopt GSM or GPRS as wireless communication mode. WiFi technology is introduced into vending machine for the first time because of its high cost of later maintenance and management. It not only has good mobility, but also can make full use of the customer's own network for personalized management. The hardware of the system is designed with master-slave structure, and the CAN-bus with multi-host function is used to connect the main control board and the drive control board. Based on this, the concept of sales cluster is realized, in which the main control board uses 32-bit arm controller. With the integration of MDB communication module and USB Host module, on the basis of the basic sales function, the function of selling data management based on U-disk or WiFi is provided. Because of the complexity of network communication and the characteristics of vending machine with many modules and high real-time requirements, the vending machine has good real-time performance. The driver is rich in open source embedded configurable operating system eCos. and under its driver framework, the driver of Ethernet Flash USB Host and other related modules is written. Through the analysis of IEEE 802.11 and other communication technologies, the wireless communication mode based on WiFi wireless card and wired communication is realized, and the remote setting and access ability of small and medium-sized customers using GoAhead embedded Web server is provided. It is more convenient than using proprietary software. The software design and development of terminal control system are based on open source software, which is in line with the current development trend. Finally, the functional test and summary of the product are carried out. The results show that the design not only increases the convenience of product network management, but also effectively improves the economic benefit of the product, which is helpful to the further promotion of vending machine.
