【正文】 on In electrification railways, in order to extend the life of the pantograph on electric lootives, so that the slider of pantograph wear evenly, the contactline (electrified railway power feed line) in straightline segments is arranged as zigzag route (curve section arranged in the form of polyline). The distance between the contactline of positioning point and the pantograph centerline track is called out staggervalue, which is a key indicator of contactline . Staggervalue can not be ignored, the value too small will affect the slider of pantograph wear evenly and the purpose of extending using life。 本科生外文文獻(xiàn)翻譯 外文題目 ： High–Speed Data Acquisition System Based on ARM amp。 LinearCCD 中文題目 ： 基于 ARM 與線性 CCD 的高速數(shù)據(jù)采集系統(tǒng) 學(xué) 部 信息科學(xué)與工程學(xué)部 學(xué)科門(mén)類(lèi) 工學(xué) 專(zhuān) 業(yè) 電子信息工程 學(xué) 號(hào) 2021480236 姓 名 倪啟蒙 指導(dǎo)教師 王蘭勛 裝 訂 線 河北大學(xué)工商學(xué)院 河北大學(xué) 工商學(xué)院 2021 屆 本科生畢業(yè)外文翻譯 1 High–Speed Data Acquisition System Based on ARM amp。 otherwise, in some cases (such as caught in a stiff winds), cause a large range of lateral movement of the roof (and the higher the speed, the greater pantograph swing around), some parts of contactline will be in excess of the effective work length of pantograph, so that the staggervalue of contactline beyond the standard range, leading to deterioration of the current collection, and even cause incorrect running of the pantograph accident. Pantographcatenary malfunction will result in interruption of train operation, which impact on rail transport seriously. In order to avoid these phenomena, the staggervalue and its changes should be tested , a lootive contactline monitoring system and its mating data acquisition system were developed, which calculate the instant staggervalue quickly. II. System Components System hardware ponents are shown in figure 1. The system consists of the following ponents: (1) using TOSHIBA Company’s highspeed linear array CCD to achieve the digitization of contactline images (CCD output the 河北大學(xué) 工商學(xué)院 2021 屆 本科生畢業(yè)外文翻譯 2 signal of corresponding time sequence of position)。 (3) using PDIUSBD12 USB interface device to plete the data munications between measurement system and the PC. Due to the characteristics of its improved Harvard structure, special instructions and quick to realize a variety of signal processing, ARM processor is widely used in image processing, munications, radar, sonar, precision machinery fields, etc. ARM processor is adopted for its arithmetic speed and
