1. 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.

•Another event has occurred, e.g. low battery warning.

•Manual communication is performed by the operator.

•At scheduled communication.

1.2. INFRA Point Vibration System

The INFRA Point unit is a data logger with one vibration sensor attached

by cable. The sensor can either be a single-axis type measuring in vertical

direction, or a triaxial type. The triaxial sensor is measuring in three

directions: vertical, longitudinal and transverse. The cable lengths can be

2, 5 or 15 meters (see section 8 Accessories). The data logger is polling

the sensor at initial startup and each measuring start to check for any

possible node loss.

The INFRA Point sensors contain the vibration sensor elements. The data

logger consists of analog measuring electronics, analog-digital converters,

an embedded microcontroller/DSP for digital signal processing etcetera, a

small color display, six-button keypad, memory card, cellular modem,

antennas and batteries. See section 3.1 for more details.

The INFRA Point unit requires INFRA Net for full remote-control

capability, data presentation, alarms/alerts configuration and setup, and

instrumentation settings. However, most instrument settings can be

handled directly at the unit using the keypad/display.

1.3. INFRA Point Enclosure

1.3.1. Data logger

INFRA Point data logger is built in a Peli™ case, which is extremely

robust and tough, and has a Gore-Tex membrane, pressure-equalizing vent

to keep the inside dry. This vent is waterproof even if the case is

completely submerged. When the case is opened, the front panel is also

waterproofed using O-rings and IPx6 specified keyboard buttons etc.

Data logger is further described in section 2.1.

1.3.2. Sensor

The enclosure is made of aluminum and includes:

•A horizontal hole for wall-mounting (M6 or ¼” bolt).

•A vertical hole for floor-mounting (M6 or ¼” bolt).

•Contains a digital id chip for calibration and traceability data.

The sensor is all molded, giving the following advantages:

•Reduced risk of sensor element (geophone) getting loose. Sensor

will be more robust.

•Built-in damping in the molding compound gives protection from

shock and high-frequency vibrations.

•Total volume and weight are reduced.

•Better sealing gives better moisture protection.

Sensor is further described in section 2.2.

Note! INFRA Point instruments are not intended to be submerged in

water.

1.4. Unpacking and Parts Identification

The INFRA Point system has been shipped in protective packaging.

Please keep this and use it when transporting your equipment.

5. ERRORS and WARNINGS

See chapter 5 for more information about this.

2.1.3. Batteries

The power supply of the INFRA Point data logger has two Li-Ion batteries

and uses the battery with the highest voltage. The switch-over between the

batteries is automatic.

If the unit is firmly mounted, the batteries can be replaced one at the time

during normal operation without interrupting the measurement See the

safety section at the beginning of this manual for how to replace the

batteries. Voltage, current, temperature and a digital identity of both

batteries are monitored to ensure safe use and charging.

Note! Make sure that both batteries are inserted.

2.1.4. Antenna

INFRA Point normally uses a ½ wave antenna attached to its TNC

connector. The antenna connector is placed on the upper side of the data

logger, see

Figure 1.

2.1.5. External Power Connector

Input for a 12V power supply is supported. When the battery level is low,

the external power will charge the batteries

. For a complete charge, the

batteries must be removed from the instrument and charged separately.

The external power connector is located to the left on the bottom side of

the data logger, see

Figure 1.

Note! Use the plastic cap to protect the external power connector

when not in use.

Only charge up to 60% to extend battery life.

2.1.6. USB Connector (Mini-B Type)

The data logger has a Mini-USB connector, mainly used for maintenance.

INFRA Point is never powered through the USB interface. Do never

monitor vibrations with the USB connected.

The Mini-USB connector is located at the center on the bottom side of the

data logger, see

Figure 1.

When set through the graphical user interface, the memory card can be

accessible as a Windows drive via the USB interface. See section 5.8.5.

Firmware upgrade is normally performed remotely via INFRA Net but

may also be done via the USB interface. See section 5.8.6.

Note! Use the plastic cap to protect the USB connector when not in

use.

Figure 2 Position of memory card, SIM card and backup battery.

2.1.7. SIM Cards

If activated when ordering, the embedded SIM card is used. This is pre-

configured for the customer.

If the customer needs to use their own SIM card, a mini-SIM card can be

inserted. The mini-SIM card must have an active “data plan”. The inserted

mini-SIM card will then be used instead of the embedded SIM card.

Figure 2 on page 15 shows where the SIM card is positioned.

Note! The PIN-code lock of the removable mini-SIM card must be

deactivated before use in INFRA Point. Contact your network provider

for pin-code lock deactivation.

When inserted, make sure that the SIM card is correctly positioned. Push

the card gently until it is fixed in place.

To loosen the card, push it slightly and it will pop out a bit. Then grasp it

with your fingers, a pair of tweezers or similar.

For activation or deactivation of the embedded SIM card, please contact

Sigicom support.

Note! The SIM card needs normally not be accessed manually.

2.1.8. Memory Card

The INFRA Point data logger uses a microSD memory card. It is used to

store recorded data, system logs and various status files to be

communicated to INFRA Net. No configuration data is saved on the

memory card. Figure 2 on page 15 shows where the memory card is

positioned.

File formats on the memory card are only compatible with the INFRA Net

server and are not described in this manual.

The memory card can be accessible as a removable drive via the USB

connector, see section 5.8.5.

If the memory card is unintentionally missing (or corrupt), an error

message will be displayed at start-up, see Appendix E.

When inserted, make sure that the memory card is correctly positioned.

Push the card gently until it is fixed in place.

To loosen the card, push it slightly and it will pop out a bit. Then grasp it

with your fingers, a pair of tweezers or similar.

Please contact Sigicom support for guidance regarding memory card

formatting or other memory card issues.

Note! Only use a memory card approved by Sigicom.

2.2. Sensors

The INFRA Point system can either be equipped with a vertical or a

triaxial sensor. The triaxial sensor is measuring in three directions:

vertical, longitudinal and transverse.

Figure 5 Triaxial sensor Figure 6 Vertical sensor

The sensors have no batteries inside. Only calibration parameters are

stored in the sensors’ memory. All other settings are stored in the data

logger.

Note! Only INFRA Point sensors may be used.

2.3. Cables

INFRA Point sensors may be attached with INFRA Point cables of

lengths 2, 5 or 15 meters, see section 8 Accessories. Several cables can be

joined to a maximum length of 30 meters.

Note! Only use specified INFRA Point cables.

3. Measuring Parts

3.1. Measuring Hardware

3.1.1. Vibration Sensors

The INFRA Point sensors uses geophones with a low frequency response

down to 4.5 Hz. The low frequency resonance of the geophones is

electrically dampened, and their characteristics are measured during

calibration and saved in the sensor’s calibration memory. This data is later

used as input for the digital frequency compensation used in some

measurement standards.

The analog geophone signal is then passed to the data logger through the

INFRA Point cable.

3.1.2. Data logger

Analog Electronics

An adjustable amplifier enhances the geophone signal according to the

selected measurement standard. The signal is then low pass filtered with

an analog filter to avoid aliasing. Then the signal passes through an

analog-digital converter and all subsequent signal processing is digital.

Analog-Digital Conversion

All sampling is performed at 4096 Hz. The analog-digital converter has a

16 bits resolution which, at measurements up to 250 mm/s (10 in/s) in the

largest range, provides a minimum resolution of 0.01 mm/s (0.0004 in/s).

In the display, the resolution of interval values is set to 0.05 mm/s (0.002

in/s) in this range.

Digital Signal Processing

The main processor of the INFRA Point data logger is a combined general

processor and a digital signal processor (DSP). The DSP part of the

processor filters, compensates and detects the signals according to the

selected measurement standard

Note! Some calibration parameters are stored in dedicated data logger

memory.

3.2. Measuring Logic

3.2.1. Measurement Standards

INFRA Point contains several pre-configured measurement standards,

used in different countries and for different types of measurements. More

standards may be added in future FW versions. Selection of appropriate

standard is done through INFRA Net or the graphical user interface.

Note! Remember to review all measurement settings after a change of

standard.

A more thorough description of the available measurement standards is

given in Appendix F.

3.2.2. Interval Measurements

INFRA Point processes the vibration signal through the filters and

detectors of the selected measurement standard. The interval value is the

maximum value of the processed signal within a selected interval time.

When the interval end time is reached, the maximum value is saved, and a

new interval is started. The timestamp of the interval is set to the interval

end time.

The interval time can be set to a value between 5 seconds and 20 minutes.

It is set through INFRA Net or the graphical user interface.
