【摘要】：所謂流動式數(shù)字電影流動放映一體機指的是能夠播放電影、具備音頻功率放大器及投影功能的機器,通過控制面板控制,其主要應用于農(nóng)村流動放映及戶外流動影院。它主要的設計組成為架構(gòu)、功能以及數(shù)據(jù)庫,三者相輔相成,缺一不可。隨著科技的不斷進步,信息網(wǎng)絡不斷地融入到廣大人民的生活之中,數(shù)字電影也開始結(jié)合網(wǎng)絡技術不斷的發(fā)展。電影放映機是典型的嵌入式設備,對其進行改良時需要結(jié)合信息網(wǎng)絡科技以及設備自身的特點,綜合考慮設備各方面的系統(tǒng)狀態(tài)。改良后的數(shù)字電影流動放映機相比于傳統(tǒng)的放映機具有很多的優(yōu)勢,并且解決了很多設備上出現(xiàn)的問題,優(yōu)化了很多使用流程措施。此設備還有操控不方便,通信及控制方式單一等眾多的問題需要研發(fā)人員不斷探索和研究,以此來解決實際問題。論文針對數(shù)字電影流動放映機進行改良設計,此次改良主要從兩個方面進行,即外觀的改良設計和功能改良設計。本文拓展改良設計的概念,強調(diào)將企業(yè)的發(fā)展也作為設計時考慮的一項重要因素,兼顧產(chǎn)品設計、制造、消費或使用等多方面的因素,從而嘗試實現(xiàn)真正的可持續(xù)性,并以其為指導進行了數(shù)字放映機的外觀改良設計;同時結(jié)合WIFI通信技術,對放映機進行功能改良,使得放映機的監(jiān)控模塊功能更加豐富,控制和資源傳輸更加方便,論文主要介紹了課題所涉及的改良設計概念、方法及嵌入式領域的相關技術包括Linux系統(tǒng)相關技術、嵌入式技術、ARM相關技術、WiFi通信技術及其Concurrent模式下的工作模型,最后對WIFI模塊進行了整體測試,較好地實現(xiàn)了項目需求。
[Abstract]:The so-called mobile digital film flow projection machine refers to a machine capable of playing movies, with audio power amplifier and projection function, controlled by control panel, which is mainly used in rural mobile projection and outdoor mobile cinema. Its main design groups are architecture, functionality and database, which complement each other and are indispensable. With the development of science and technology, the information network has been integrated into the lives of the vast numbers of people, and the digital film has also begun to develop in combination with the network technology. Film projector is a typical embedded device. It is necessary to consider the system status of all aspects of the equipment in combination with the information network technology and the characteristics of the equipment itself. The improved digital film flow projector has many advantages compared with the traditional projector, and solves the problems in many equipments and optimizes many measures of using the flow chart. There are many problems, such as inconvenient operation, single communication and control mode, which need to be explored and studied to solve practical problems. The improved design of digital film flow projector is mainly carried out from two aspects, that is, the improved design of appearance and the improved design of function. This paper expands the concept of improved design and emphasizes that the development of the enterprise is also an important factor in the design, taking into account the factors of product design, manufacture, consumption or use, so as to try to achieve true sustainability. At the same time, with the help of WIFI communication technology, the function of projector is improved, which makes the function of monitor module of projector more abundant, and the control and resource transmission more convenient. This paper mainly introduces the concept of improved design, methods and related technologies in embedded field, including Linux system related technology, embedded technology, ARM related technology, WiFi communication technology and its work model under Concurrent mode. Finally, the WIFI module is tested as a whole and the project requirements are well realized.
