数据采集

The infrared remote controller is a cheap, small, simple, reliable and effective product. It can effectively resist electromagnetic interference and ensure safe operation of the system. Using remote technology can reduce manipulative difficulty during soil bin testing and realize single operation of the whole system. Practical application many times demonstrated that the infrared remote controller can work reliably and improve work efficiency considerably.Besides control the movement of tester, the soil bin tester driving control system can adjust the tester speed by rule and line, which was impossible to former test equipments. The range can be adjusted from -1.45m/s to 1.45m/s, the positive and minus sign denotes the direction of tester running.

土槽台车动力控制系统的控制参数均通过人机交互界面输入；系统能够实现对台车行驶速度、位移和时间的实时采集、显示和存储功能，并设有对数据库的操作功能，方便试验人员对数据的查询、修改、删除和保存；试验过程中系统为试验人员提供了台车速度曲线，并能实时动态显示，用来监测台车的运行状况；为了确保试验过程中试验设备和人员的安全，系统增加了控制台车行驶位移和时间的功能；系统使用的防脉冲干扰平均值法处理采集的数据，剔除奇异项，减少了干扰在有用信号中的比重，并能直接显示出所采集数据的均值和方差，节省了处理数据所需的大量时间，提高了工作效率。

Nextly, develop a fault diagnosis data collecting system which solved real-time dataacquisition in the power system fault diagnosis, the data message is analysed in detail andextract the data required in fault diagnosis, this system can not only collect data but alsotransmit the data information to attemper and provide a necessary condition for electric powersystem fault diagnosis On-line.

其次，开发电力系统故障诊断数据信息采集系统，该系统解决了电力系统故障诊断过程中故障特征信息很难实时获取的问题，同时对数据报文进行了详细的分析，提取出故障特征信息，该系统不但可以采集数据，而且还可以将数据信息实时传送至调度，为电力系统大规模在线故障诊断提供了必要的条件。

So during the collection of fault sample data and checking data, the paper sets up the mathematics model of control system first. We cause all kinds of fault in the control system, then collects a variety of fault data. After unitarily dealing, the fault data server as the sample data of training neural network. At the same time, according to the collection of checking data, it examines whether the trained neural network have the function of fault diagnosis.

在故障样本数据及检验数据的采集过程中，首先建立了控制系统的数学模型，人为地让控制系统发生各种故障，从而采集到各种故障数据，经过归一化处理后，作为训练神经网络的样本数据；同时，也采集检验数据，用以检验训练出的神经网络是否能够起到故障诊断的作用。

It consists of same three sets of acquisitive circuits,which construct O-shaped structure to sample the signals without drop .And it adopts threshold judging method to determine the valid data in the process of the acquisition,abandons vast of the redundant useless data at the same time,it only sends the useful data to the host computer by the way of DMA,so it is easy to processing the data.The design is concise and reliable.

但这本身也是一对矛盾，因为随着采集速度的提高，单位时间内采集的信号数据也就越多，而一般的采集卡在采集一定数量的数据后，总的需要一定的时间向主机内存传送数据，而在这段时间内是不能采集数据的，作为随机信号，如果在此时间内到来，则会造成信号的丢失。

Taking the communication server as the core,the data transmission layer collects data from other intelligent devices with 103 protocols,Modbus protocols,pro-bus protocols or TCP / Modbus protocols,which are converted as dual Ethernet network data and then transmitted to monitoring system and dispatch center via hub.

重点介绍了通信网络的构成，网络管理层基于TCP/IP的以太网络通信，采用站内103通信规约，数据传输层以通信服务器为核心，向下采集其他智能设备数据，支持任何采用103规约及采用Modbus通信规约、pro-bus通信规约或采用TCP/Modbus协议的智能设备，并将采集到的数据转换成以太网双网数据，通过交换机上传至监控系统及调度中心。

A portable field information acquisition system is designed based on single chip,nonvolatile memory chip, GPS and several kinds of sensors. It can gather and recordthe information of GPS, sensors of field information acquisition and display them byLCD.

该系统可以同时采集和记录GPS、土壤水分、养分、温度等多种传感器的数据，通过液晶显示屏现场即时查看数据、记录数据；用户可将采集记录的数据通过USB总线或者串口发给微机，在微机上形成Excel表格或者文本文件，方便用户进行数据分析。3。

The method can make the students improve the insight and the application in computer, and is worth extending to some other experiments. CCD, Zeeman effect, gray

为此进行了改进，保留了传统实验的精华，增加了图像处理、CCD数据采集及计算机应用等，从最佳参数下实

Related international standard organizations are iso, iec, itu and upu. the rfid system is mainly made up of data acquisition and database network.

相关的国际标准化机构主要有：国际标准化组织、国际电工委员会、国际电信联盟、世界邮联等。rfid系统主要由数据采集和后台数据库网络应用系统两大部分组成。

In this paper, we designed a new Langmuir probe system based on integrate-and-dump network.

本文着重介绍了积分网络，对其工作原理，电路结构，提高探针信噪比做了详尽阐述，并以积分网络为基础设计出一套基于计算机的新型积分Langmuir探针系统，包括探针电源部分和数据采集部分。

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.

交际能力和语法的关系应该是目标与途径的关系。
