Readings are logged at a rate specified by the user.SD Card Information•Insert an SD card (from 1G size up to 16G) into the SD card slot at the bottom of the meter. The card must be inserted with the front of the card (label side) facing toward the rear of the meter.•If the SD card is being used for the first time it is recommended that the card be formatted and the logger’s clock set to allow for accurate date/time stamping during datalogging sessions.Refer to the Setup Mode section for SD card formatting and time/date setting instructions.•European and USA numerical formats differ. The data on the SD card can be formatted for either format. The meter defaults to USA mode where a decimal point is used to separate units from tenths, i.e. 20.00. The European format uses a comma, i.e. 20,00. To change this setting, refer to the Setup Mode section.Manual DataloggingIn the manual mode the user presses the LOG button to manually log a reading onto the SD card.1. Set the sampling rate to ‘0’ seconds as described in the Setup Mode section.2. Press and hold the LOG button for at least 1.5 seconds and the DATALOGGER icon will appearon the LCD; the lower portion of the display will show p-n (n = memory position number 1-99).Note that if PSI is set as the unit of measure it appears as P51 (where a ‘5’ is used as an ‘S’) in the same area of the LCD where memory locations are shown. This can be disorienting at first.3. Momentarily press the LOG button to store a reading. The DATALOGGER icon will flash eachtime a data point is stored.4. Use the ▲ and ▼ buttons to select one of the 99 data memory positions in which to record.5. To exit the manual datalogging mode, press and hold the LOG button for at least 1.5 seconds.The DATALOGGER icon will switch off.Automatic DataloggingIn automatic datalogging mode the meter takes and stores a reading at a user-specified sampling rate onto an SD memory card. The meter defaults to a sampling rate of two seconds. To change the sampling rate, refer to the Setup Mode section (the sampling rate cannot be ‘0’ for automatic datalogging):1. Select the sampling rate in the Setup Mode to a value other than zero.2. Press and hold the LOG button for at least 1.5 seconds. The meter will flash the DATALOGGERicon at the selected sampling rate indicating that readings are now being automatically recorded to the SD card.3. If a card is not inserted or if the card is defective, the meter will display SCAN SD indefinitely. Inthis case, switch the meter OFF and try again with a valid SD card.4. Pause the datalogger by pressing the LOG button momentarily. The DATALOGGER icon willstop flashing and the sample rate will display for a short time. To resume logging simply press the LOG button again momentarily.5. To terminate the datalogging session press and hold the LOG button for at least 1.5 seconds.6. When an SD card is used for the first time a folder is created on the card and named VBD01.Up to 99 spreadsheet documents (each with 30,000 readings) can be stored in this folder.7. When datalogging begins a new spreadsheet document named VBD01001.xls is created on theSD card in the VBD01 folder. The data recorded will be placed in the VBD01001.xls document until 30,000 readings are reached.8. If the measurement session exceeds 30,000 readings, a new document will be created(VBD01002.xls) where another 30,000 readings can be stored. This method continues for up to99 documents, after which another folder is created (VBD02) where another 99 spreadsheetdocuments can be stored. This process continues in this same fashion with folders VBD03through VBD10 (last allowable folder).SD Data Card to PC Data Transfer1. Complete a datalogging session as detailed in above in the previous sections. Hint: For thefirst few tests, simply record a small amount of test data. This is to ensure that the datalogging process is well understood before committing to critical, large scale datalogging.2. With the meter switched OFF, remove the SD Card.3. Plug the SD Card directly into a PC SD card reader. If the PC does not have an SD card slot,use an SD card adaptor (available at most outlets where computer accessories are sold).4. Power the PC and run a spreadsheet software program. Open the saved documents in thespreadsheet software program (see example spreadsheet data screen below).Spreadsheet data exampleRS-232/USB PC InterfaceThe optional 407001A software kit (software and cable) allows streaming of data to a PC viathe RS232 Output jack.AC Power AdaptorThis meter is normally powered by six (6) 1.5V ‘AA’ batteries. An optional 9V power adaptor is available. When the adaptor is used, the meter is permanently powered and the power button will be disabled.Battery Replacement and DisposalWhen the low battery icon appears on the LCD, the batteries must be replaced. Several hours of accurate readings are still possible in this condition; however batteries should be replaced as soon as possible:•Remove the two (2) Phillips screws from the rear of the meter (directly above the top of the tilt stand).•Remove and safely place the battery compartment and screws where they will not be damaged or lost.•Replace the six (6) 1.5V ‘AA’ batteries observing polarity.•Replace the battery compartment cover with the two (2) Phillips screws.All EU users are legally bound by the battery ordinance to return all used batteries tocollection points in your community or wherever batteries / accumulators are sold!Disposal in the household garbage is prohibited!SpecificationsDisplay Backlit LCD; LCD size: 52 x 38mm (2 x 1.5”)Status indicators Over-range audible beep and low battery display iconFrequency Range 10Hz to 1kHzDatalogger Sampling Rate AUTO LOGGING: From 1 to 3600 seconds.MANUAL LOGGING: Set the sampling rate to ‘0’ seconds Memory Card SD memory card; 1G to 16GB sizeData Hold Freeze the displayed readingMemory Recall Record and Recall the Maximum and Minimum readingsDisplay update rate Approx. 1 secondData Output RS-232 / USB PC computer interfaceOperating Temperature 0 to 50°C (32 to 122°F)Operating Humidity 85% R.H. max.Auto Power OFF A fter 10 minutes of inactivity (can be disabled)Power Supply Six (6) 1.5 VDC batteries (optional 9V AC adaptor)Power Consumption Normal operation (backlight and datalogger OFF): approx. 5mAdcWith backlight OFF and datalogging ON: approx. 25mAdcWith backlight ON add approx. 12mAdcWeight 343g (0.75 lbs.) w/ batteries; 241g (0.53 lbs.) w/o batteriesDimensions Meter: 182 x 73 x 47.5mm (7.1 x 2.9 x 1.9”)Vibration sensor: round 16mm (0.63”) diameter, 37mm (1.46”)lengthElectrical SpecificationsFunction Unit Range Accuracym/s20.5 to 199.9 m/s2g 0.05 to 20.39 G ft/s2 2 to 656 ft/s2± ( 5%rdg + 2 d ) @ 80 and 160HzAccelerationCalibration Point: 50 m/S^2 ( 160 Hz )mm/s 0.5 to 199.9 mm/scm/s 0.05 to 19.99 cm/s inch/s 0.02 to 7.87 inch/s ± ( 5%rdg + 2 d ) @ 80 and 160HzVelocityCalibration Point: 50 mm/s ( 160 Hz )mm 1.999mm inch 0.078inch ± ( 5%rdg + 2 d ) @ 80 and 160HzDisplacementCalibration Point: 0.141 mm ( 160 Hz )Above specification tests under the environment RF Field Strength less than 3 V/M & frequency less than 30 MHz only and 23±0.5ԨCopyright © 2011 Extech Instruments Corporation (a FLIR company)All rights reserved including the right of reproduction in whole or in part in any form。

电力RTU基础知识

电力RTU基础知识

电力远程终端控制系统RTU基础知识知识点1.RTU英文全称 Remote Terminal Unit,中文全称为远程终端控制系统。

RTU(Remote Terminal Unit)是一种远端测控单元装置,负责对现场信号、工业设备的监测和控制。

与常用的可编程控制器PLC相比,RTU通常要具有优良的通讯能力和更大的存储容量,适用于更恶劣的温度和湿度环境,提供更多的计算功能。

正是由于RTU完善的功能,使得RTU产品在SCADA系统中得到了大量的应用。

RTU具有的特点是:1、通讯距离较长2、用于各种环境恶劣的工业现场3、模块结构化设计,便于扩展4、在具有遥信、遥测、遥控领域的水利,电力调度,市政调度等行业广泛使用。

远程终端设备(RTU)是安装在远程现场的电子设备,用来监视和测量安装在远程现场的传感器和设备.RTU将测得的状态或信号转换成可在通信媒体上发送的数据格式。

它还将从中央计算机发送来得数据转换成命令,实现对设备的功能控制.监视控制和数据采集是一个含义较广的术语,应用于可对安装在远距离场地的设备进行中央控制和监视的系统。

SCADA系统可以设计满足各种应用(水、电、气、报警、通信、保安等等),并满足顾客要求的设计指标和操作概念。

SCADA系统可以简单到只需通过一对导线连在远端的一个开关,也可复杂到一个计算机网络,它由许多无线远程终端设备(RTU)组成并与安装在中控室的功能强大的微机通信。

SCADA系统的远程终端设备可以用各种不同的硬件和软件来实现。

这取决于被控现场的性质、系统的复杂性、对数据通信的要求、实时报警报告、模拟信号测量精度、状态监控、设备的调节控制和开关控制.变电站是电力系统的一个重要组成部分,它的安全可靠运行是电网安全经济运行的根本保证。

当前变电站正以分项自动化向着综合自动化方向发展,综合自动化的近期目标是把变电站的保护、测量、监控、远动等融为一体,取得数据共享,资源共享,大幅度提高自动化的功效。
