7 DAQ Theory Data acquisition (DAQ) is the process of sampling signals that measure real world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. The components of data acquisition systems include: Sensors that convert physical parameters to electrical signals. Signal conditioning circuitry to convert sensor signals into a form that can be converted to digital values. Analog-to-digital converters, which convert conditioned sensor signals to digital values. In this assignment we will use more advanced and DAQ hardware used in the industry today (Wi-Fi DAQ, ZigBee, crio, cdaq, etc.) not the simple USB-6008 that you are familiar with

12 Types of Wireless DAQ Theory Here are some examples: Cellular Bluetooth ZigBee Wireless USB Wi-Fi Wireless HART 12

13 Theory Wireless DAQ See Tutorial Wireless Data Acquisition in LabVIEW for more details... 13

14 DAQ with Web Services Theory A growing trend is to use a technology built on TCP and HTTP called Web Services. A Web Service is an application programming interface (API) that can be accessed via HTTP requests. When called, Web Services return a human-readable response. Modern Web Services use JSON responses but other response options are XML, HTML, or plain text. 14

15 DAQ with Web Services Theory There are several reasons why engineers and IT departments are choosing Web Services over other communication technologies. First, Web Services are straightforward and simple to access from any programming language, including C++, Objective C, C# and LabVIEW. Second, since Web Services sit on top of common network protocols, the communication is considered IT friendly compared with proprietary network protocols. Third, Web Services can also be easily encrypted via industrystandard technologies like Secure Sockets Layer (SSL) or Transport Layer Security (TLS). 15

23 DAQ System Hans-Petter Halvorsen, M.Sc.

24 Implement your DAQ System, eg.: Sensor incl. Transmitter Pt-100 DAQ Hardware Wi-Fi DAQ ZigBee DAQ crio Ethernet/Wi-Fi/ZigBee Make a proper GUI for Monitoring Data 24

25 Sensors Calibration: A comparison between measurements. One of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible with a second device. The device with the known or assigned correctness is called the standard. The second device is the unit under test, test instrument, or any of several other names for the device being calibrated. Resolution: The smallest change it can detect in the quantity that it is measuring. The following formula may be used (where S is the measurement span, e.g., 0-100deg.C): Theory Accuracy: How close the measured value is the the actual/real value, eg., ±0.1 % In the assignment you need to deal with these parameters. You find information about these parameters in the Data sheet for your device
