National Instruments has released a new wireless gateway and three new measurement nodes that extend the capabilities of the NI wireless sensor network (WSN) platform and illustrate the company's commitment to wireless measurement technology. Through the NI LabVIEW graphical development environment, engineers are believed to use the new WSN gateway to easily integrate wired and wireless measurement and control systems and program WSN nodes to perform local control, data analysis and event-based alarming or notification. The new devices offer increased performance and expanded connectivity to thousands of sensors and instruments.
Engineers can insert the NI 9795 C Series gateway into any available slot in a CompactRIO chassis to complement existing measurement and control systems with wireless I/O. The new NI WSN-3214 strain/bridge completion node brings waveform acquisition capabilities to the WSN product line and delivers the ideal product for wireless structural health monitoring of bridges, buildings and equipment. The new programmable NI WSN-3230 (one-port RS232) and NI WSN-3231 (one-port RS485) serial nodes can wirelessly control and interface with serial-based instruments, sensors and control boards.
Professor Sharon L. Wood, University of Texas at Austin, Department of Civil, Architectural and Environmental Engineering said, "With NI wireless sensor networks, we can easily monitor critical structures without running excessive lengths of cables. We use the LabVIEW-programmable WSN nodes to perform onboard analysis of strain data to achieve an in-depth understanding of the structural response."
The ability to augment existing wired systems with wireless measurements is increasingly important as the adoption of wireless measurement technology continues. With these new devices, engineers can use a single software environment to create complete wired and wireless measurement and control systems, which are supposed to be ideal for applications such as environmental monitoring, industrial measurements and control, energy monitoring and structural health monitoring.
