【摘要】：隨著科技和信息技術(shù)的發(fā)展，微型打印機(jī)作為最主要的信息輸出設(shè)備，被廣泛的應(yīng)用在日常生活中的各個(gè)領(lǐng)域，而且新的應(yīng)用場景層出不窮，尤其是對(duì)移動(dòng)便攜打印機(jī)的需求更是與日劇增，比如政府部門的移動(dòng)警務(wù)系統(tǒng)、移動(dòng)執(zhí)法系統(tǒng)等現(xiàn)場打印執(zhí)法文書等，由于這些應(yīng)用直接面對(duì)用戶，而且需要將打印樣條長時(shí)間的保存，因此在這些場景中對(duì)打印機(jī)的功耗、便攜性、可靠性、打印質(zhì)量等性能指標(biāo)有著更高的要求。同時(shí)隨著微電子技術(shù)的飛速發(fā)展，嵌入式芯片逐漸成為各種智能設(shè)備的首選方案，是因?yàn)槠渚哂懈咝阅�、低成本的�?yōu)勢，本系統(tǒng)正是基于以上背景，設(shè)計(jì)了基于ARM Cotex M3內(nèi)核主控芯片的微型針式打印系統(tǒng)。 文中首先介紹了微型打印系統(tǒng)的應(yīng)用背景及其控制系統(tǒng)的主流發(fā)展趨勢，，在分析國內(nèi)外研究現(xiàn)狀的基礎(chǔ)上提出了系統(tǒng)的設(shè)計(jì)目標(biāo)與內(nèi)容，即完成了一個(gè)微型針式打印系統(tǒng)的軟硬件設(shè)計(jì)工作，基于該系統(tǒng)的打印機(jī)有體積小、功耗低、操作簡單、接口豐富等優(yōu)點(diǎn)；然后基于設(shè)計(jì)目標(biāo)對(duì)系統(tǒng)的功能性需求進(jìn)行了分析并且得出了系統(tǒng)的非功能性需求；接下來在系統(tǒng)需求分析的基礎(chǔ)上完成了系統(tǒng)總體設(shè)計(jì)，即對(duì)系統(tǒng)的工作原理以及軟硬件平臺(tái)的選型進(jìn)行了詳細(xì)的介紹，確定了基于ARM Cotex M3內(nèi)核的STM32F103X作為主控芯片的設(shè)計(jì)方案；系統(tǒng)的硬件平臺(tái)在詳細(xì)設(shè)計(jì)過程中遵循層次化、模塊化的設(shè)計(jì)思想，最終完成了打印系統(tǒng)硬件電路的設(shè)計(jì)，主要包括主控芯片及外圍電路、通信接口、系統(tǒng)開關(guān)機(jī)控制、異常狀態(tài)檢測及處理、電池充電、按鍵和顯示以及機(jī)頭驅(qū)動(dòng)等部分；在軟件設(shè)計(jì)過程中，結(jié)合針式打印系統(tǒng)的特點(diǎn)和模塊化設(shè)計(jì)原則，分別對(duì)數(shù)據(jù)接收、數(shù)據(jù)處理、機(jī)頭控制、狀態(tài)檢測及異常處理等各個(gè)模塊進(jìn)行了編程和調(diào)試，最終完成了整個(gè)系統(tǒng)的軟硬件詳細(xì)設(shè)計(jì)工作；最后結(jié)合系統(tǒng)各項(xiàng)需求，對(duì)系統(tǒng)功能和性能方面的測試過程進(jìn)行了介紹。 本文基于完善的設(shè)計(jì)實(shí)例，對(duì)方案論證、需求分析、系統(tǒng)設(shè)計(jì)及實(shí)現(xiàn)、系統(tǒng)測試的整個(gè)過程進(jìn)行了詳細(xì)的闡述，由于在電子系統(tǒng)和嵌入式系統(tǒng)設(shè)計(jì)過程中設(shè)計(jì)思想和方法是基本相似的，因此本文對(duì)同類系統(tǒng)的設(shè)計(jì)具有較好的參考價(jià)值。
[Abstract]:With the development of technology and information technology, micro printer, as the most important information output device, has been widely used in every field of daily life, and new application scenes are emerging in endlessly. In particular, the demand for mobile portable printers has increased dramatically, such as government mobile policing systems, mobile law enforcement systems and other on-site printing of law enforcement documents. Because these applications are directly facing users, Moreover, the printing splines need to be saved for a long time, so there are higher requirements for printer power consumption, portability, reliability, printing quality and other performance indicators in these scenarios. At the same time, with the rapid development of microelectronics technology, embedded chip has gradually become the first choice of various intelligent devices, because it has the advantages of high performance and low cost. This system is based on the above background. A micro needle printing system based on arm Cotex M3 core control chip is designed in this paper. Firstly, the application background of the micro printing system and the mainstream development trend of the control system are introduced. Based on the analysis of the present research situation at home and abroad, the design objectives and contents of the system are put forward, that is, the hardware and software design of a miniature needle printing system is completed. The printer based on the system has the advantages of small volume, low power consumption and simple operation. Then the functional requirements of the system are analyzed based on the design objectives and the non-functional requirements of the system are obtained. Then the overall design of the system is completed on the basis of the analysis of the system requirements. That is, the working principle of the system and the selection of software and hardware platform are introduced in detail, and the design scheme of STM32F103X based on arm Cotex M3 kernel as the main control chip is determined, and the hardware platform of the system follows the hierarchy in the detailed design process. The design idea of modularization finished the design of hardware circuit of printing system, including main control chip and peripheral circuit, communication interface, system switch machine control, abnormal state detection and processing, battery charging, In the process of software design, combining the characteristics of needle printing system and the principle of modular design, the data receiving, data processing, head control, etc. Every module of state detection and exception handling is programmed and debugged, and the software and hardware of the whole system are designed in detail. This paper introduces the testing process of the system function and performance. Based on the perfect design example, this paper expounds the whole process of the scheme demonstration, requirement analysis, system design and implementation, system test in detail. Since the design ideas and methods are basically similar in the design process of electronic system and embedded system, this paper has a good reference value for the design of the same kind of system.
