【摘要】：隨著電子技術(shù)和網(wǎng)絡(luò)技術(shù)的不斷發(fā)展,嵌入式系統(tǒng)在工業(yè)控制領(lǐng)域有了廣泛的應(yīng)用,并且隨著數(shù)據(jù)采集和發(fā)布系統(tǒng)的自動化程度提高,我們在一些特殊環(huán)境下使用數(shù)據(jù)采集和發(fā)布系統(tǒng),對提高生產(chǎn)效率和保護(hù)工作人員有著重要的意義。本文利用嵌入式Linux和網(wǎng)絡(luò)技術(shù)結(jié)合,實現(xiàn)采集遠(yuǎn)程的設(shè)備數(shù)據(jù),通過互聯(lián)網(wǎng)達(dá)到遠(yuǎn)程監(jiān)控設(shè)備的目的。 首先,基于嵌入式Linux數(shù)據(jù)采集與發(fā)布系統(tǒng)的分析,設(shè)計了系統(tǒng)的總體框圖,包括系統(tǒng)運(yùn)行的硬件平臺和軟件平臺,數(shù)據(jù)采集模塊,Web服務(wù)器Boa模塊,嵌入式數(shù)據(jù)庫模塊。 其次,完成了數(shù)據(jù)采集系統(tǒng)的硬件設(shè)計和軟件設(shè)計。在硬件設(shè)計方面,其核心是基于三星公司的ARM920T內(nèi)核的S3C2440A芯片,選用了256M的NAND FALSH、2M的NOR FLASH以及64M的SDRAM等作為存儲器件,并擴(kuò)展了晶振、復(fù)位、電源管理等外圍電路和USB2.0、RS232串口等通用接口,擴(kuò)展了10M/100M以太網(wǎng)接口。在軟件方面,移植了源代碼開發(fā)的Linux操作系統(tǒng)作為系統(tǒng)的軟件平臺,并制作了可讀寫的yaffs2根文件系統(tǒng)；程序方面主要是對數(shù)據(jù)采集應(yīng)用程序的算法和實現(xiàn)進(jìn)行了分析介紹,完成了數(shù)據(jù)采集應(yīng)用程序的編寫。 最后,在嵌入式系統(tǒng)下完成了對Boa服務(wù)器和SQLite數(shù)據(jù)庫的移植工作,在因特網(wǎng)上的用戶通過目標(biāo)板的IP地址就可以查詢遠(yuǎn)程設(shè)備的相關(guān)數(shù)據(jù)。
[Abstract]:With the continuous development of electronic technology and network technology, embedded system has been widely used in the field of industrial control, and with the degree of automation of the data collection and release system, we use the data collection and release system in some special environment, have important significance to improve production efficiency and protecting staff. According to the use of embedded Linux and network technology, realize remote data acquisition equipment, to achieve the purpose of remote monitoring via the Internet.
First, based on the analysis of embedded Linux data acquisition and distribution system, we designed the overall block diagram of the system, including the hardware platform and software platform, data acquisition module, Web server Boa module, and embedded database module.
Secondly, the hardware design and software design of data acquisition system. In the aspect of hardware design, the S3C2440A is the core chip of the Samsung Corp based on the ARM920T kernel, the 256M NAND FALSH, 2M NOR FLASH and 64M SDRAM as the storage device, and extends the oscillator, reset, power management circuit and USB2.0, RS232 serial interfaces, extended 10M/100M Ethernet interface. In software, transplantation of the Linux operating system source code development as software platform of the system, and made a read-write yaffs2 root file system; the procedure is mainly realized and analyzes data acquisition application algorithm, complete the data acquisition application program.
Finally, the migration of Boa server and SQLite database is completed under the embedded system. Users on the Internet can query related data of remote devices through the IP address of the target board.
