System Operational Overview

System Operational 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 data acquisition from the wireless

sensor network: SensorCloud™ and Node Commander

. SensorCloud™ is an optional web-

based data collection, visualization, analysis, and remote management platform based on cloud

computing technology. Node Commander

is used for configuring gateways and nodes, selecting

sampling modes and parameters, initializing data acquisition, and viewing and saving data.

The operational overview describes system hardware and software setup, and the basic

navigation of Node Commander

used to configure the node and begin data acquisition. A brief

overview of porting data to SensorCloud™ is also included. This section is included as a quick start

guide and is not a complete demonstration of all system and software capabilities.
