Data Acquisition

NI Data Acquisition Hardware Families

NI offers a range of individual multifunction DAQ devices in several form factors, but for guaranteed scalability and flexibility, consider one of National Instruments’ modular hardware platforms such as PXI and NI CompactDAQ, which comes in available USB, Ethernet, and Wi-Fi communication buses.

NI’s data acquisition hardware portfolio contains hundreds of devices across a spectrum of price points and functionality.

 

Simple Complete USB Data Acquisition

NI CompactDAQ provides the plug-and-play simplicity of USB to sensor and flexibility of modular instrumentation. The modular design can measure up to 256 channels of electrical, physical, mechanical, or acoustical signals in a single system.NI CompactDAQ can measure dynamic signals such as sound, vibration, and pressure at up to 50 kS/s per channel in addition to static signals such as DC voltage and temperature.

 

Other modules provide single-point and waveform output capability at rates up to 100 kS/s/channel, or digital I/O at rates up to 10 MHz. Some of the more recently released modules add measurements such as 5A current input, ±300 Vrms measurement, and 24-bit precision high-speed analog input.

NI CompactDAQ & NI CompactRIO is an Integrated, Modular Solution

Deploy Anywhere: -40 to 70 deg C operating temperature; 5g vibration, 50 g shock; Class 1, Div II location certified; Ventless

 

Each C Series module option to a specific type of measurement. If you want to measure temperature, use thermocouple modules.  If you want to measure voltage, choose analog input modules. Over 60 NI and 3rd Party C Series Modules.

 Each dedicated module is integrated, meaning that these data acquisition devices combine all of the necessary components (physical connectivity, signal conditioning) into single devices and all you need to do is supply the sensor and signal.

 

Furthermore, most C Series modules can also be used on the RIO platform from National Instruments, in case you need the determinism of a real-time OS or the reconfigurability of an FPGA.

Wireless data acquisition

Wireless data acquisition: NI Wi-Fi DAQ & NI WSN.

Depend of application you need to choose use NI WIFI DAQ or NI WSN. NI WI-FI DAQ-s are meant to stream data continuously back to a host PC or laptop. It use IEEE 802.11b/g technology.  A wireless sensor node (WSN) is typically a low-power, autonomous battery-operated device intended for long-term deployment in applications where measurements are needed only every few minutes, hours, or even days. WSN is done according to IEEE 802.15.4.

Wi-Fi data acquisition devices, on the other hand, behave in much the same way as a USB data acquisition device – a host PC collects data continuously (in real time) as the device acquires it. Both technologies are adopted to use indoors and outdoors.

 

Because the NI CompactDAQ chassis uses the same NI-DAQmx driver software as other NI data acquisition devices, you can develop your applications using NI LabVIEW; LabWindows™/CVI; ANSI C/C++; or Microsoft C#, Visual Basic, or Visual Basic .NET.

NI Wi-Fi Data Acquisition Devices

Wi-Fi data acquisition is an extension of PC-based data acquisition to measurement applications where wiring is difficult or cost-prohibitive. Wi-Fi data acquisition (DAQ) devices combine IEEE 802.11 wireless or Ethernet communication, direct sensor connectivity, and the flexibility of NI-DAQmx software for remote monitoring of electrical, physical, mechanical, and acoustic signals. The NI cDAQ-9191 holds a single C Series module and is capable of streaming continuous waveform data on each channel at more than 50 kS/s with 24 bits of resolution.

The NI cDAQ-9181 and NI cDAQ-9191 support over 50 NI C Series modules with measurements including voltage, current, temperature, force, strain, acceleration and many more. C Series modules offer direct sensor connections, NIST-traceable calibration, and built-in signal conditioning for a variety of measurements, including temperature, high-voltage digital I/O, strain, acceleration, current, and voltage. In addition to the NI cDAQ-9191 wireless chassis, you can use C Series modules interchangeably for measurement and control applications with different chassis, including 4- and 8-slot NI CompactDAQ chassis and CompactRIO, as well as the NI USB-9171 single module chassis and NI cDAQ-9181 Ethernet chassis. Download NI C Series Module Compatibility Chart [PDF].  View all C Series modules .

In addition, built-in NIST-approved 128-bit AES encryption and advanced IEEE 802.1X network authentication offer the highest commercially available network security (WPA2 Enterprise).  Authentication ensures that only authorized devices have network access, and encryption prevents data packets from being intercepted. Lean more in Tutorial.

NI wireless sensor network (WSN)

The NI wireless sensor network (WSN) platform provides a complete remote monitoring solution that consists of NI LabVIEW graphical programming software and new reliable, low-power wireless nodes for remote measurements. The NI WSN platform offers reliable connectivity from a gateway to end nodes at a distance of up to 300 m line of sight. Using mesh networking, routers extend the total distance from a gateway to an end node. Each wireless network can scale from tens to hundreds of nodes and seamlessly integrate with existing wired measurement and control systems.

Based on the IEEE 802.15.4 standard, the NI WSN protocol supports mesh routing, which means a WSN router can relay measurements from end nodes to a central gateway. If a primary router is unavailable and an alternate router exists, the protocol automatically routes measurements through the alternate path. 

The combination of LabVIEW and NI WSN measurements provides a reliable, low-power system for remote monitoring:  Industrial / Machine Condition / Distributed Temperature / Environmental /Energy / Structural Health / Transportation.

WSN Architectures

Combine different types of nodes and gateways to meet the unique needs of your application.

Create a simple, PC-based wireless sensor network (WSN) monitoring system with the NI WSN-9791 Ethernet gateway, or a headless, embedded monitoring system with the NI 9792 programmable gateway, which can run deployed NI LabVIEW Real-Time applications. For applications that require the combination of high-speed I/O (or control) and distributed wireless monitoring, take advantage of the NI 9795 C Series WSN gateway.

NI WSN-9792 Architecture

With the flexibility of Ethernet connectivity, you can add other devices and functionality to your WSN system. This can range from enterprise-level devices such as databases and servers to wired I/O, control systems, or third-party WSN products. LabVIEW Real-Time allows embedded data logging and open communication on the gateway, while the LabVIEW WSN Module allows node customization and local decision making at the node level.The NI  gateway connects through standard Ethernet to Windows PCs or LabVIEW Real-Time controllers.

LabVIEW also provides native Web services for remote data access and visualization over the Internet.  Besides the advanced processing and visualization capabilities that are common in LabVIEW, LabVIEW Web services give you the opportunity to publish your measurement data to a Web server, such as the integrated Web server on the NI 9792, delivering convenient remote access to your WSN from virtually anywhere. With this complete system architecture, you can quickly and easily acquire data using an NI WSN, process and host that data on a server, and then access the data conveniently and remotely from a wireless smart device, such as an iPhone or laptop.

The NI WSN-3202 voltage node offers four 16-bit analog inputs with ±10, ±5, ±2, and ±0.5 V selectable input ranges; four digital I/O lines; and the ability to source up to 20 mA at 12 V for powering external sensors. The NI WSN-3212 thermocouple input node provides four 24-bit thermocouple channels with support for J, K, R, S, T, N, B, and E thermocouple types; four digital I/O lines; and the ability to source up to 0.5 A on digital output channels.

Reconfigurable I/O (RIO)

NI reconfigurable I/O (RIO)

 

 

 

 

 

 

 

 

 

 

 

NI RIO   technology is based on four components: a processor, a reconfigurable field-programmable gate array (FPGA), modular I/O hardware, and graphical design software. Combined, these components give you the ability to rapidly create custom hardware circuitry with high-performance I/O and unprecedented flexibility in system timing control.

RIO technology gives you the ability to define your own custom measurement hardware circuitry using reconfigurable FPGA chips and LabVIEW graphical development tools. The RIO core includes an FPGA chip and surrounding circuitry that enable LabVIEW to perform hardware synthesis.

Using off-the-shelf RIO hardware and the LabVIEW FPGA Module, you can define your own hardware without in-depth knowledge of hardware design tools or hardware description languages. Whether you need analog, digital, or counter I/O or more complex I/O for communication protocols or control signals, you can develop LabVIEW code to connect directly to your signal using RIO technology. When the signal requirements change, you can modify, recompile, and download the LabVIEW code to the FPGA to change the I/O number, mix, or type.Additionally, you can use the built-in LabVIEW functions for signal processing and discrete linear and nonlinear control to build digital control systems for rates up to 20 MHz and analog control systems for rates up to 150 kHz.This flexibility can save you valuable time and money because you can reuse the same hardware and software, which means no extra cost.

 

RIO technology and NI platforms

RIO technology, found throughout the NI platform, includes NI PCI and PXI R Series DAQ devices, the compact vision system, and CompactRIO. Use the R Series DAQ devices for custom data acquisition or real-time I/O applications. Develop custom FPGA logic on the compact vision system to add triggering, pulse-width modulation signals, or custom communications protocols to your machine vision application. For maximum flexibility in embedded measurement and control applications, use the CompactRIO family, which provides the benefit of modular FPGA-timed I/O with built-in signal conditioning and direct signal connectivity.

Here’s the current matrix of NI RIO hardware products for solving embedded, industrial and test applications.
