【摘要】：近年來(lái),隨著嵌入式技術(shù)優(yōu)點(diǎn)的不斷釋放,嵌入式系統(tǒng)在社會(huì)各大領(lǐng)域得到了廣泛的運(yùn)用并有著較高的關(guān)注度。嵌入式倉(cāng)庫(kù)監(jiān)控系統(tǒng)就是其中較為熱門的應(yīng)用點(diǎn)之一。倉(cāng)庫(kù)作為存儲(chǔ)民生物資的地點(diǎn),在生產(chǎn)環(huán)節(jié)中有著較為重要的地位。為了保證物資的安全以及存儲(chǔ)環(huán)境的要求,這就需要對(duì)倉(cāng)庫(kù)進(jìn)行視頻監(jiān)控以及溫濕度采集。傳統(tǒng)的監(jiān)控系統(tǒng)一般都是將視頻監(jiān)控系統(tǒng)和溫濕度采集系統(tǒng)進(jìn)行分離,分別進(jìn)行實(shí)現(xiàn)。隨著相關(guān)技術(shù)的發(fā)展,前端一體化、報(bào)警智能化以及報(bào)警聯(lián)動(dòng)性等特點(diǎn)將會(huì)大面積普及,以往的模式將存在著一定的局限性。 本文以嵌入式技術(shù)、視頻技術(shù)和網(wǎng)絡(luò)技術(shù)為基礎(chǔ),設(shè)計(jì)并實(shí)現(xiàn)了一款基于嵌入式Linux的倉(cāng)庫(kù)監(jiān)控系統(tǒng)。其前端以嵌入式S3C2440為控制核心、STC89c51單片機(jī)作為采集模塊處理器進(jìn)行搭建,在對(duì)硬件和軟件進(jìn)行了總體設(shè)計(jì)之后,重點(diǎn)研究并實(shí)現(xiàn)了TCP/IP協(xié)議網(wǎng)絡(luò)下的嵌入式前端TCP方式的溫濕度及控制信號(hào)傳輸和UDP方式的視頻傳輸；實(shí)現(xiàn)了基于Video4Linux(V4L)技術(shù)對(duì)視頻圖像信息的采集；最后在QT Creator下對(duì)界面進(jìn)行了設(shè)計(jì)以及完成了相互之間信號(hào)與槽的關(guān)聯(lián)。 該嵌入式倉(cāng)庫(kù)監(jiān)控系統(tǒng)采用ARM+51單片機(jī)的設(shè)計(jì)方案,使得系統(tǒng)前端集成度較高、可靠性好、功耗低、成本低廉,有著一定的經(jīng)濟(jì)實(shí)用性。
[Abstract]:In recent years, with the continuous release of the advantages of embedded technology, embedded system has been widely used in various fields of society and has a high degree of concern. Embedded warehouse monitoring system is one of the most popular applications. Warehouse, as a place where people's livelihood goods are stored, plays an important role in production. In order to ensure the security of materials and the requirements of storage environment, it is necessary to carry out video surveillance and temperature and humidity acquisition. The traditional monitoring system usually separates the video surveillance system from the temperature and humidity acquisition system and implements them separately. With the development of related technology, the features of front end integration, alarm intelligence and alarm linkage will be popularized in a large area, and the previous models will have some limitations. Based on embedded technology, video technology and network technology, a warehouse monitoring system based on embedded Linux is designed and implemented in this paper. The front-end is built with embedded S3C2440 as the control core, and the STC89c51 microcontroller is used as the processor of the acquisition module. After the overall design of the hardware and software, The temperature and humidity of the embedded front-end TCP and the transmission of the control signal and the video transmission of the UDP mode are studied and realized in the TCP/IP protocol network. The acquisition of video image information based on Video4Linux (V4L) technology is realized. Finally, the interface is designed under QT Creator and the correlation between signals and slots is completed. The embedded warehouse monitoring system adopts the design scheme of ARM 51 single chip microcomputer, which makes the front end of the system have high integration, good reliability, low power consumption, low cost, and has certain economic practicability.
