The AISTS is a
comprehensive smart sensor that was built to access, upload, and
download data from areas that are not traditionally accessible due to
metal enclosures or barriers.
This technology utilizes advanced sensing schemes that are
customizable for applications that have a need to monitor, analyze, or
maintain assets with such constraints. The non-intrusive AISTS has
through-metal data and energy transferal capability by ultrasound, but
it can also be easily setup with conventional powering and
communication electronics. The device can last between charges for 1
month (active) up to 1 year (sleep) with a miniature 450 mAh
rechargeable battery.
Optimized Size, Weight, and Power (SWaP)
with Intelligent Processing
This ultra low power, self-sufficient, and
advanced smart sensor, designed with optimized SWaP and embedded
intelligent algorithms, builds upon an advanced rad-hard
microcontroller to accurately measure, detect, log, and report
events related to the health, status, or environment of monitored
systems. Low power operation (3.3v, 487.94 μA in active mode, 57.02
μA in sleep mode) enables event registration and logging data for
extended periods of time to later be downloaded by a host system or
mobile device.
Standardized & Advanced Embedded Features
A
custom subset of embedded functions from the IEEE 1451 Standard
provides a
communication protocol, fault detection awareness by fast
notifications, and Transducer Electronic Data Sheet (TEDS) management.
Specifications of each unit as well as a unique identification are
provided within TEDS. Intelligent health monitoring features such as
diagnostics, calibration support, sensor self-diagnosis, among others
are all provided within a common software structure.
Customizable
and Flexible Smart Sensor
AISTS' modular design is based on a
Main-Board, a small
Satellite-Board with customizable transducers, expansion bus (I2C,
UART, IrDA,
SPI,
GPIO, and
ADC
channels), and a rechargeable battery. The Satellite Board's
state-of-the-art vibration sensing suite has a high performance analog
3-axis accelerometer and digital 3-axis accelerometer with features
such as impact detection (requires just 144
μW)
and activity monitoring. Even if in sleep mode,
monitoring is possible since the Main Board's
ultra-low power, stand-alone temperature sensor identifies temperature
events, while the digital
accelerometer monitors impact or shock.
Operation as a Non-Intrusive and Standalone Smart Sensor with Debriefing
Capability
A Hand
Held Reader with a standardized communication protocol allows sending
commands to and downloading health data logs from the AISTS. RS-232,
SPI,
and ZigBee are communication interfaces between the Reader and the
AISTS. However, for applications that require through wall
energy
and data transfer, an ultrasound system is used. Communication modules
can be customized to many devices such as the ruggedized Trimble Nomad®.
