Remote configuration and monitoring

*Over-the-Air Configuration

OTAC*

The BeanScape® application allows the user to view all the data trans-

mitted by the BeanDevice® AX-3D

With the OTAC (Over-the-Air configuration) feature, the user can remo-

tely configure the BeanDevice® AX-3D.

Several data acquisition modes are available on the BeanDevi-

ce® AX-3D :

Low Duty Cycle Data Acquisition mode (LDCDA): the data acquisi-

tion is immediately transmitted by radio. The transmission fre-

quency can be configured from 1s to 24h.

Alarm Mode : the measured value is transmitted by radio when-

ever an alarm threshold (fixed by the user) is detected (4 alarm

threshold levels High/Low).

Survey Mode : operates like the Alarm mode but the device

sends frequently a beacon frame informing its current status.

Streaming Packet Mode: all measured values are transmit-

ted by packet within a continuous flow at 5000 samples per sec-

ond maximum

Streaming Mode: all measured values are transmitted in real-time

within a continuous flow at 100 samples per second maximum

Math Mode : Values such as the mean value, minimum value,

maximum value and standard deviation are calculated on sample

time series and transmitted by radio .

The BeanScape® Premium+ integrates an OPC DA server (Data Access).

OPC DA is particularly well suited for real time measurement and data

sharing. Each data/measurement can be associated to a tag or its attrib-

utes and shared with one or many OPC clients.

AX-3D

Antenna Diversity

While the vast majority of wireless sensors shows their

limits in harsh industrial environment, the

BeanDevice® AX-3D integrates an innovative antenna

diversity design, allowing to optimize the radio link quality

in environments subject to random and diverse

disturbance. Antenna diversity improves both the quality

and reliability of a wireless link by 30%.

Rethinking Sensing Technology

Embedded Data Logger up to

1,000,000 data acquisition records

The BeanDevice® AX-3D integrates an embedded Datalogger, which can be used to log data when a

Wireless Sensor network can not be easily deployed on your site. All the data acquisition are stored on the

embedded flash and then transmitted to the BeanGateway® when a Wireless Sensor Network is established.

The Datalogger feature is compatible with all the data acquisition mode available on your

BeanDevice® AX-3D :

LowDutyCycle Data Acquisition

Alarm

Math

Streaming & Streaming packet ( maximum data rate : 1 Ksamples per second for each axis)

Example: Vibration Analysis on

windmills blades

The BeanDevice® AX-3D is

configured with its Datalogger

feature. A standalone installation

of the BeanDevice® AX-3D will be

done on the windmills blades,

without the necessity to be

connected to the BeanGateway®.

Once the blades starts rotating,

each data is recorded on the

embedded flash.

When the windmill is for mainte-

nance, a technician working on

the site can send a request for a

log transmission. Then the

BeanDevice® AX-3D starts sen-

ding all its logs . If all the logs are

sucessfully transmitted to the

BeanGateway®, the flash memory

is erased and new logs will be

recorded.
