System Operation Overview

The gateway is the interface between LORD MicroStrain

®

sensor nodes and the data acquisition

computer.  The gateway co-ordinates the configuration and sampling of the nodes and can handle

many nodes simultaneously. Communication between the nodes and gateway is wireless and

uses the LORD MicroStrain

®

LXRS

®

data communications protocol. LXRS

®

nodes, and many

legacy nodes, will communicate with any LXRS

®

gateway.

LORD MicroStrain

®

has two software programs available for the Wireless Sensor Network: the

Node Commander

®

Software Suite and SensorCloud™. Users can also write their own programs

by utilizing the LORD MicroStrain

®

Wireless Sensor Networks Data Communications Protocol.

The

Node Commander

®

Software Suite

is included with all data gateways and is also

available on the LORD MicroStrain

®

website for download. It includes the following

programs:

l

Node Commander

®

is used for configuring nodes and acquiring, viewing, and

saving data. 

l

Live Connect

is a TCP/IP-to-serial conversion tool that translates the

communications between Node Commander

®

and an Ethernet gateway. This

program is only used with the WSDA

®

-1500 - LXRS

®

or other Ethernet gateways.

l

WSDA

®

Data Downloader

is used to download acquired data from the flash

memory card embedded in an applicable gateway to a host computer. This program

is only used with the WSDA

®

-1500 - LXRS

®

or other Ethernet gateways.

SensorCloud™

is an optional data collection, visualization, analysis, and remote

management tool. It is based on cloud computing technology and is accessed directly from a

web connection.

Automatic, real time data collection is available through Ethernet

gateways, such as the WSDA

®

-1500 - LXRS

®

 and any already collected data can be easily

uploaded for visualization and analysis. Because it is web-based, SensorCloud™ requires

no installation. For more information

see Data Processing on page 22

.

This operational overview describes system hardware and software setup, including gateway and

node communication, and an overview of the Node Commander

®

software menus required to

configure a sensor connected to the node and begin data acquisition.  A brief overview of porting

data to SensorCloud™ is also included. This section is intended as a quick start guide and is not a

complete demonstration of all system and software capabilities.
