摘 要

本文在分析比較了國(guó)內(nèi)外的相關(guān)數(shù)據(jù)采集記錄儀的優(yōu)缺點(diǎn)后，重新提出了一款改進(jìn)了的新型數(shù)據(jù)采集記錄儀。和傳統(tǒng)的數(shù)據(jù)采集記錄儀相比，它采用了SamSung公司基于ARM公司生產(chǎn)的ARM920T處理器核為核心的S3C2410x處理器，使用了64M內(nèi)存芯片的同時(shí)還增加了NAND FLASH K9F6408U0C、FLASH MEMORY AM29F040B,大大的增加了數(shù)據(jù)采集記錄儀的數(shù)據(jù)存儲(chǔ)處理能力；在操作控制方面，簡(jiǎn)化了操作按鍵，添加了一個(gè)觸摸屏操作界面，使得操作控制變得更為簡(jiǎn)單；同時(shí)還擴(kuò)展了IIC接口、SPI接口、IIS接口、JTAG接口、USB接口等，使得數(shù)據(jù)采集記錄儀器擴(kuò)展能力大大增強(qiáng)，以滿足各種情況下的不同要求！

ABSTRACT
Based on the analysis of the advantages and disadvantages, which is about the domestic data acquisition recorder and internationals’, this article re-proposes a new type of improved data acquisition recorder.Compare to the traditional data acquisition recorder, it uses the S3C2410x processors beening made by the SsmSung company which is based on the ARM company’s ARM920T processor core, the the 64 M memory chip and increas- sing the NAND FLASH K9F6408U0C and FLASH MEMORY AM29F040B. All of these, greatly increase the recorder’s storage capacity. In operational control process, the adding of the touch screen interface and the reducing of the operation buttons, make the operational control easier. At the same time, the expanding of the IIC interface, SPI Interface , IIS interface, JTAG interface and the USB interface, making the recorder greatly enhance ability to expand, so that it can meet the various requirements of the different circumstances!

Keywords：Data acquisition, ARM9, S3C2410, Linux, the embedded systems
