NI Expands Wireless Sensor Network (WSN) Platform

NI Expands Wireless Sensor Network (WSN) Platform New WSN Gateways and Measurement Nodes Expand Wireless Communication and Measurement Functions

Press Release-September 2010-NI recently released NI 9792 and NI WSN-3226, which expands the wireless communication and measurement capabilities of the NI Wireless Sensor Network (WSN) platform. The new NI 9792 is a programmable WSN gateway that can communicate with NI WSN measurement nodes and other hardware through a variety of open communication standards. The gateway integrates the NI LabVIEW real-time controller and the built-in WSN wireless transceiver, which can help implement LabVIEW real-time applications running locally on the gateway and collect data from NI WSN devices. NI 9792 is ideal for embedded wireless data logging applications . The new NI WSN-3226 voltage / resistance temperature detector (RTD) multifunction node can support resistance-based measurements such as RTDs and potentiometers, and can be combined with voltage and temperature measurements on one NI WSN device to expand Test function of NI WSN platform.

Users can use the LabVIEW Real-Time Module to program the NI 9792 gateway for independent operation. The gateway contains a high-performance 533 MHz processor and 2 GB of onboard storage for embedded data logging applications; it also has built-in Web (HTTP) and file (FTP) servers to help users use smartphones, mobile computers, etc. Thin client devices remotely access measurement data. NI 9792 includes RS232 serial port and Ethernet dual port, which can provide flexible connection with equipment such as enterprise network or wired I / O system. This flexibility helps engineers and scientists create complete wired / wireless measurement solutions that meet the requirements of various applications.

The new WSN-3226 measurement node adds resistance-based measurement to the NI WSN platform. It has four analog input channels, and each channel can be individually configured for ± 10 V voltage measurement or resistance measurement. With the new measurement node, engineers and scientists can flexibly select high-speed and high-resolution analog input modes on the device, weighing the relationship between the sampling performance required by the application and the device energy consumption. WSN-3226 also has two bidirectional digital channels, each channel can be configured as input, drain output or source output. In addition, the measurement node can be powered by four AA batteries to obtain up to 3 years of continuous working time, or you can choose to be powered by an external power supply of 5 to 30 V to improve the execution efficiency of large power applications.

Using LabVIEW WSN Module Pioneer, engineers and scientists can add more customized WSN-3226 node operations to achieve more intelligent functions, such as extended battery life, improved analog and digital input performance, local control, analysis, data reduction, and Connect with custom sensors, etc. In addition, NI WSN has launched the latest version of the driver software-NI WSN 1.2, which can support WSN-3226. Under the latest software, WSN's firmware update is faster, the time stamp is more accurate, and I / O variables can be automatically deployed. The software also supports the configuration of the NI 9792 gateway based on the Web, without the need to install any application software to configure and install the WSN system.

NI WSN products are ideal for long-term data recording and remote monitoring, and can be used in the following applications:
-Environmental monitoring
-Energy consumption monitoring
-Building monitoring
-Structural health testing
-Distributed temperature monitoring
-traffic
-Industrial monitoring
