This paper discusses smart sensors which are a critical element to monitoring, control, and evaluation processes as needed to support ground based testing for rocket engine test. Sensor applications involve tens to thousands of sensors; their reliable performance is critical to achieve overall system goals. These system engineering trade-offs include the familiar constraints of power, signal conditioning,...
We demonstrated an actual Implementation of smart sensor technology based on IEEE 1451.1 and 1451.4 standards. The device is embedded with a MCU, FLASH memory, SRAM, eight analog-to-digital channels, and a 2.4 GHz wireless module. The implementation successfully demonstrated the sensor's plug- and-play capability through the use of a transducer electronic data sheet (TEDS). First, the TEDS is resided...
IEEE 1451 is an emerging standard that facilitates the communication between smart sensors with network communications for an interoperable sensor network. Moreover, it provides plug-and-play capability through standardization of the transducer interfaces. This paper is on the creation of a test suite that specifies tests such as conformance and functionality. Test cases have been developed to check...
Smaller, faster, and cheaper sensors resulted from continuing advances in sensor, semiconductor, and communication systems technology makes it possible to have real sensor intensive networks of fixed and mobile devices for use in many in-door and out-door applications. Several sensor network testbeds have been developed, but none of them consider how to incorporate smart sensor capability in the system...
Design and implementation of a testbed for testing and verifying IEEE 1451-compatible sensor systems with network performance monitoring is of significant importance. The performance parameters measurement as well as decision support systems implementation will enhance the understanding of sensor systems with plug-and-play capabilities. The paper will present the design aspects for such a testbed...
