Data Acquisition System & Data Logger Data Acquisition System & Data Logger Presentation Transcript

  • DATA ACQUISITION SYSTEM AND DATA LOGGER TRIVEDI JAY A. 09 EC 27
  • DATA ACQUISITION SYSTEM
  • OBJECTIVE What is DAQ?? Short history Block diagram Working of DAQ Component of DAQ Why we use DAQ Types of DAQ Application of DAQ sources
  • WHAT IS DAQ??• Data Acquisition is the sampling of real world data• It is the national instrument which measure the physical data and convert that data in digital form.• That digital form is calculated by transducers/other sensors.• Process, analyze, store, and display the acquired data with the help of software
  • SHORT HISTORY• First in 1963 it invented its call by IBM 7700 Data Acquisition System• IBM 1800 Data Acquisition and Control System.• In 1974 S-100• In 1981 IBM Personal Computer and Scientific Solutions it was the first pc data acquisition system
  • DAQ BLOCK DIAGRAM
  • COMPONENTS OF DAQ • Each data acquisition system has unique functionality to serve application- specific requirements, all systems share common components that include,• Signals & sensors• signal conditioning• DAQ hardware• computer with software.8/24/11
  • 8/24/11
  • SIGNAL PROCESSING• Electrical signals are conditioned so they can be used by an analog input board. The following features may be available: Amplification Isolation Filtering Linearization
  • WHY WE USE OF DAQ ??• Collecting data from in any physical component is very time consuming process• But by the use of DAQ system it allows the automatic data collection and made it easy.
  • Types of Data Acquisition Systems 8/24/11
  • APPLICATION OF DAQ• THE VARIOUS APPLICATIONS ARE AS UNDER• Data Acquisition• Integrated Systems• Advance control• Software techniques• DSP technology• Case study

  • DATA LOGGER
  • OBJECTIVE What is data logger?? Short history Types of data logger Application of data logger Working specification sources
  • WHAT IS DATA LOGGER??• Data logger is an electronic device that records data over time .• It is located either with a built in instrument or sensor via external instruments and sensors.• digital processor• They generally are small, battery powered, portable, and equipped with a microprocessor
  • SHORT HISTORY First data logger was a CR7. It was basically invented 28 years before today. Then made improvement
  •  Data logger is a device which is used for measuring the data like; if we want to measure the temperature of railway rail the data logger is attached at various distance and by the computer device we can see and compare the whole temputere.
  • TYPES OF DATA LOGGER Mechanical data logger Electronic data logger Wireless data loggers Temperature , Humidity data logger
  • APPLICATION OF DATA LOGGER Electric Utility Applications Meteorological Applications Process Industry Applications Mobile / Vehicle Test Applications Environmental Studies Applications Mining Industry Applications Water/Wastewater Utility Applications Water Resource Applications
  • WORKING SPECIFICATION Dimensions: 6.05"H x 3"W x 2.05"D (153.7mMH X 76.2mm W x 52mm D) Software compatible with Windows 98, NT SP6, Windows 2000, and Windows XP Requires 70MB of hard drive space Temperature: –5oF to 150oF + 1oF (-20oC to 65oC + 0.5oC) Humidity: Operating 0 to 100% (calibrated accuracy 15 - 85% + 5% RH)
