数据采集

The control software connects with PCI driver to send order to the measurement system, in order to initialize the system and start collection. It will access the time domain data in RAM and frequence domaim data in DSP through PCI bus, finish data transfer automaticly, display the data in many ways such as graphicness and table, and store the data into harddisk at the same time.

SDRAM is used as image storage, which can store many frames image data to provide the foundation for the correlation operation between frames. FIFO is a data buffer for real-time image. All of these make the image processing system simple design, decreasing the write-read time and solving the question of transmission and delay, and allowing the data processing and the data grabbing at the same time. The processed results can be output in 20ms, so the bandwidth of the C6000-based image processing system is improved.

系统采用SDRAM作为图像存储器，可以存储多帧图像数据，为实现帧相关运算奠定了基础，实时图像数据采用FIFO作为缓存，使系统设计简单，读取速度快，解决了数据传输的瓶径问题，同时也减少了传输延时，实现了对图像数据边采集边处理，减少了系统的滞后时间，当场给出电视脱靶量，提高了图像处理系统的带宽。

The implementation steps are that the seismic data is collected; the Fourier transform is made for the seismic data at a certain time window; a low pass filter operator of the time domain with an interception frequency of FE and a sampling rate of DT is calculated, which is taken as the equivalent N point smooth operator; FE and DT satisfy the equation that FE*DT is equal to X*DF*1.024; the estimate value of the amplitude spectrum of the seismic wavelet and the reverse wavelet are obtained, which are convoluted with the original seismic data; and the deconvolution seismic data of the time window is obtained.

实施步骤是采集地震数据，对某一时窗的地震数据做傅立叶变换，计算截止频率为FE和采样率为DT的时间域低通滤波算子作为等效N点平滑算子，FE与DT满足FE*DT＝X*DF*1.024，进而得到地震子波振幅谱估计值和反子波，再与原始地震数据褶积，得到该时窗的反褶积后地震数据。

So concentrator can sample data from acquisition unit and transmit command to acquisition unit.

采集器用于实时采集电力参数且自带RS—485通信接口，集中器可随时对其进行数据的采集和命令的发布。

After gathering GPS data from Beijing Sanjidian station, the paper made a research on transformation and rotation of coordinates. GPS data is displayed on computer appropriately and that verifies the design at the same time.

采用北京三家店车站现场采集的GPS数据，研究了实测数据与屏幕坐标数据的坐标变换，采用坐标旋转实现了地图数据的合理显示，还结合实际数据，对数字轨道地图的实现进行了实验验证。

An image acquisition system snapping three instantaneous images at the same time with a color image board has been designed, it can obtain homochromy laser spot images at difference orientation in ICF experiment.

设计和开发了利用单块彩色图象采集板实现三通道并行瞬态图象采集系统，利用它可同时测量ICF实验不同方位的激光焦斑单色图象，并将采集图象实时传送到数据处理中心。

Data collected in site can be eventually be converted to knowledged data which is required in practical application i.e information only after they have been processed organized and maintained.

惠煜 ，刘世英，马秦晋现场采集的数据只有在经过了数据整理、数据组织、数据处理、数据维护等过程后，才能最终转换成实际应用所需要的知识化数据，即信息。

Because there are relative obturating among technologies of different GIS and different requests on Geo-data from different specialties, the spatial data produced by different departments with individual method is stored in different medium .

以上数据的生产过程和质量，常常只是对数据的生产者来说是透明的，而对数据的使用者却不透明，这样必然导致数据生产过程中大量的重复采集数据的工作。

This article uses HK-2000C integration numeral pulse sensor developed by HuaKe Electronic Technology Research Institute. It is used to collect pulse signal of subjects into computer and store them in data file. Designed the pulse signal collection system,time domain analysis system and frequency domain analysis system using LabVIEW software. 134 objects are taken, including 73 healthy person, 61 coronary disease and hypertension patients. Analysed the signal using time domain and frequency domain system, then compared each analysis method.

本文采用肥华科电子技术研究所研制的HK-2000C集成化数字脉搏传感器，将测试者的脉搏信号采集到计算机中，并且以数据文件格式存储应用labVIEW软件设计了脉搏信号的采集系统时域分析系统频域分析系统取检测对象134例，其中健康人73例，冠心病高血压患者61例将采集的信号进行时域频域分析，并对各种分析方法进行比较

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
