Abstract
Over the past several years, DRDC Atlantic has embarked on a program for the evaluation of existing technologies as well as the development of new technologies for application in platform specific health monitoring systems. It has been envisioned that dedicated sensor, hardware, and software suites may be employed to provide engineering officers with real time monitoring with respect to the performance of critical ships systems. The current study is focused primarily on the evaluation of conductive polymers with respect to their potential application as a general strain-sensing element for monitoring structural loading. A prototype wireless hardware/software suite has been developed for the acquisition of resistive element potential data from conductive polymer sensors. The hardware and software algorithms have been configured to support data acquisition from multiple, concurrently active remote sensor stations. The acquisition hardware is comprised of a general-purpose multifunction board coupled to a 433 MHz RF transceiver. Transmitted data from the remote sensor stations is received by a RF base station and bussed to a PC data logger for storage and post processing. Two software programs have been developed to control the functionality of the system. The first program includes the algorithms to acquire the data from the strain sensors attached to an autonomous, remotely located RF station, and transmits the data to the RF base station. The remote sensor station program has
