Introduction 

1.1.

 

INFRA System 

The INFRA field measurement system consists of rugged sensors which 
sends data and status to INFRA Net, where it is processed, stored and 
presented through a web interface. There are sensors which monitor 
several important quantities at construction sites and infrastructure 
projects, such as vibration, noise and dust etcetera. 

All data is sent to INFRA Net, using the built-in cellular modem, at 
various occasions: 

•

 

Monitoring is started or stopped. 

•

 

A trigger event has occurred. 

•

 

An error event has occurred. 

•

 

Manual communication is performed by the operator. 

•

 

At scheduled communication.

INFRA C20 Vibration Monitor 

The C20 instrument is a complete wireless vibration monitor measuring in 
vertical direction. It consists of vibration sensor elements, analog 
measuring electronics, analog-digital converters, an embedded 
microcontroller/DSP for digital signal processing etc., a small color 
display, a six-button keypad, a memory card, a cellular modem, antennas 
and batteries. 

The C20 instrument requires INFRA Net for full remote control 
capability, data presentation, alarms/alerts configuration and setup, and 
instrumentation settings. However, most instrument settings can be done 
directly at the unit using the keypad/display.
