A new era in rugged, distributed data acquisition
13 December 2017
Acquiring accurate data during testing is fundamental, so NI has announced the rugged, distributed and synchronised FieldDAQ devices.
The growing sophistication of complex electromechanical systems, such as vehicles, aircraft and industrial equipment, means that validation test must become more rigorous to keep pace with innovation. The automotive industry in particular faces strict requirements from evolving government standards and rising customer expectations for new features such as advanced driver assistance. To help ensure the safety, reliability and quality of these systems, acquiring accurate data during testing is fundamental.
To meet these needs, test engineers are moving away from centralised measurement systems that can be susceptible to noise, and toward distributed measurement nodes, in which the digitisation and signal conditioning occurs as close to the sensors as possible. Yet more distributed measurement topologies create new challenges. Not only must DAQ devices withstand harsh test environments, they must also acquire synchronised data over an entire system and scale and integrate seamlessly.
NI’s new FieldDAQ devices are the most rugged NI DAQ devices ever created; they can acquire accurate, reliable measurements in the most severe test cell and outdoor environments, including rain, sleet, snow or mud. FieldDAQ devices have an ingress protection rating up to IP67 (dust and water resistant), can operate in -40 to 85°C environments and can sustain 100g shock and 10g vibration.
These rugged DAQ devices are built on the flexible and configurable hardware and software platforms that NI is known for, which sets them apart. With open and expandable FieldDAQ solutions, test engineers can keep pace with product design cycles and help reduce the overall cost of test, as opposed to the limitations of existing devices with functionality defined by closed, proprietary software.
“Due to rapid production cycles, no one test is the same,” said Mark Yeager, engineer/lead programmer at Integrated Test and Measurement. “Design engineers tweak the size, performance and efficiency of each component, so our test setups must evolve to meet these requirements. To reduce cost, we must be able to maximize hardware and software reuse, while still adapting to changing requirements.”
FieldDAQ also incorporates Time Sensitive Networking (TSN), the next evolution of the IEEE 802.1 Ethernet standard, providing extremely tight synchronisation over a distributed network of DAQ nodes without additional cabling or complex programming. FieldDAQ expands the NI TSN product offering, joining Industrial Controllers, CompactDAQ and CompactRIO. Additionally, because it incorporates TSN, FieldDAQ is capable of being used with third-party TSN solutions from major industrial I/O and control vendors like Bosch Rexroth, B&R Automation and Schneider Electric.
