coremicro® Reconfigurable Embedded-Smart Sensor Node (CRE-SSN)
The CRE-SSN is a smart sensor node with advanced embedded processing, flexible communication modules, and low power consumption. Accompanying PC Graphical User Interface (GUI) software provides a fast way to set up networks of CRE-SSNs, and an Application Programming Interface (API) allows custom software design. At its core, the CRE-SSN serves as a data acquisition hub where sensor suites are customizable for connecting up to five different types of sensors per module. The CRE-SSN can be deployed as a wireless sensor node by RF ZigBee, and networks of CRE-SSNs can be deployed and coordinated by the PC GUI software. Systems can be deployed in a modular way (rail mounting) by stacking several modules along with a power module (that serves several nodes). For distributed configurations, each CRE-SSN requires a complementary power module for standalone operation. The CRE-SSN support customization with flexibility to configure the module with diverse sensor suites (accommodating both analog and digital output sensors)

This ultra low power, miniaturized (1.7"x1.7"x1.1"), and multi-functional smart sensor provides high performance functions with (i) robust data acquisition, (ii) IEEE 1451 software stack with a standard communication protocol, fault detection awareness, and Transducer Electronic Data Sheets management; (iii) flexible on-board communications (I2C, UART, IrDA, SPI, and RS232); and (iv) wireless communications (ZigBee). Building on the baseline features, the CRE-SSN can be customized (optional) for hosting embedded intelligent functions such as: (a) Health monitoring by processing signals from the attached transducers (single unit or suites) and feeding internal pattern recognition software; (b) valid data generation by sensor self-diagnostics; (c) sensor calibration; and (d) sensor self-identification. Systems can be implemented by deploying CRE-SSNs with either legacy or new transducers. Available options accomodate both vibration and general purpose transducers.

Structural Health Monitoring Vibration Transducer Options:
coremicro® Reconfigurable Embedded - Smart Sensor Node for Vibration Measurement (CRE-SSN-VM). For sampling vibration measurements and providing Structural Health Monitoring capability, this version is available which contains accelerometers for monitoring machinery (such as motors and pumps) and tracking vibration levels signatures associated with specific events during operational conditions.
General Purpose Transducer Options:
To provide tracking capability of physical parameters in a monitoring system (such as Condition Based Maintenance and Health Monitoring type systems) general purpose transducers are available to obtain data (by configuration of sensor suites). Available options include the following, where these options can even be combined based on a user's requirements (e.g. both flow and pressure readings):
-
coremicro® Reconfigurable Embedded - Smart Sensor Node for Flow Measurement (CRE-SSN-FM). This version comes with Hall Effect Sensors that can be inserted in-line into a pipeline that enable measuring rate flows for a low cost and ultra-low power solution.
-
coremicro® Reconfigurable Embedded - Smart Sensor Node for Temperature Measurement (CRE-SSN-TM). This version comes with analog temperature sensors that have NPT threads for inserting into a pipeline. Combined with embedded calibration functions and TEDS, the CRE-SSN-TM can be used with advanced Condition Based Maintenance. Customizable for other operational ranges and requirements.
-
coremicro® Reconfigurable Embedded - Smart Sensor Node for Pressure Measurement (CRE-SSN-PM). This version comes with analog pressure sensors in the ranges of either100 or 500 psig with output signals between 0.5 to 4.5V and that have NPT threads for inserting into a pipeline. These sensors require a supply current with a maximum value of 15 mA. The sensor is designed for a pressure overload of two times the normal range (minimum) with an output load of 1 MO. Customizable for other operational ranges and requirements.

Systems Health-Monitoring Design Services
Network of CRE-SSNs enable distributed hardware platforms where processing can be distributed at the edge. This platform can be complemented with AGNC's software toolsets for a fully intelligent system suitable within high performance health monitoring applications. Advanced analysis tools include: Optimized Neuro Genetic Fast Estimator (ONGFE) for designing Artificial Neural Networks; Real-Time Kernels for feature extraction (time and frequency domain as well as wavelet analysis); and custom GUIs for complete system visualization and analysis. This full set of capabilities has been demonstrated successfully in NASA and DoD applications.
