Data Acquistion

DAQ or DAC - abbreviations for Data Acquisition.

DAQ is a means of inputting and outputing electronic signals to and from the real world, this is why it is also called I/O - Input and Output.

Systems that use DAQ data are automated or programmed devices like PCs, PLCs, PACs, Tablets, Embedded Micros, Industrial Computers, even Win 8, Android & Apple Smart Phones and iPods now.

Instrumentation like DVM, DMM, Scopes, Generators etc are special types of DAQ devices, either converting real world signals or generating real world electronic signals. See Instruments

Many of these instruments can be interfaced directly to programmable devices like Computers, Smart Phones, Tablets etc using various interfacing methods - RS-232/485, Canbus, GPIB, USB, Ethernet & Wifi and Bluetooth Wireless.

Some examples of real world signals (data) :-

Analog in and out - 0-10VDC, +/-10VDC, 230VAC, +/-10 Amps DC or AC and 4-20mA

Digital out - DC Levels such as TTL/CMOS, Higher voltage DC using Open Collector or FET, AC or DC voltages using Relay, SSR etc

Digital in - TTL/CMOS, Isolated volts or current DC or AC, Dry contacts

Digital timing I/O, on/off, pulse stream, PWM

Digital timing I/O, on/off, counting, period or frequency

Digital quadrature for encoders giving distance and direction.

Analog Conditioning for transducers and sensors like strain gauges, RTDs, TCs, Thermistors etc

How Data Acquistion Works

DAQ systems take Input signals and convert them into bits (numbers) and store them into memory inside the programmable device.
or

Take digital data inside a programmable device and generate Output signals represented by the data.

Interface Methods

Various interfacing means are used to connect DAQ devices to PCs, PLCs, PACs, Micros, Industrial Computing etc.

The most common methods to connect DAQ devices or boards are:-

Sockets - ISA, PCI, PCIe, PXI, cPCI, VXI, PCMCIA, Cardbus

Embedded Sockets - PC-104, PC-104+, ITX, and many more

UART Ports - RS-232, 422, 485, CanBUS, ModBus

HDR - High Data Rate Ports - USB, Ethernet

T&M Instruments - IEEE-488 - GPIB

Local Wireless - WiFi, Bluetooth, Zigbee.

Remote Wireless DAQ - GSM and 3/4G

Types of DAQ converters

There are four main types of converters for DAQ.

SAR =Successive Approximation, used for general purpose applications, can be accurate and fast.

Flash - Used for ultra high speed measurement

Integration - Used in high accuracy devices -DMMs.

Sigma Delta as used in PC sound systems and almost all audio equipment. Very accurate, low noise.

Trends in DAQ

It was very common a few years back to have one converter and a MUX or multiplexer feeding that one converter to make multichannel systems.

Now that the cost is low for ADC or DAC converters, many DAQ units have converter s on each channel, allowing for simultaneous channel sampling, and it removes a layer of in accuracy the MUX added.

DAQ Used in Climatic Wind Tunnel for Vehicle Testing

A new model automobile must be thoroughly tested in climate extremes before it is put into production. Will the heater keep the passengers warm in a blizzard? Will the cabin be cool enough in the desert summer? Can the engine cope with temperature extremes? Auto manufacturers now answer all of these questions by placing a new prototype automobile in a climatic wind tunnel. Read More
