This thesis studies the feasibility of developing a smart shipboard sensor network. The objective of the thesis is to prove that sensors can be made smart by keeping calibration constants and other relevant data such as network information stored on the sensor and a server computer. Study will focus on the design and implementation of an Ipsil IP(micro)8930 microcontroller, which is then connected, by the standard TCP/IP implementation, to a network where the sensor information can be seen using a web page. The information to make the sensor "smart" will be stored on the Ipsil chip and server computer and can by accessed by a HTML based program. By taking pre-computed calibration constants that minimize the measurement errors and writing them through the web page stored in the Ipsil chip's EEPROM, the calibrated sensor reading can be calculated. The expected contribution from the research effort would be a reduction in manpower, increased efficiency, and a greater awareness of plant and equipment operation among naval vessels, specifically the DDX. Hardware is relatively inexpensive, reliable, and COTS (Commercial Off the Shelf) available. If implemented, a Smart Shipboard Sensor Network would allow the watch standers, CHENG, OOD, and CO, to all see the same information about the ship.s engineering plant and equipment. A prototype sensor test bed was constructed in the laboratory, which consists of an Ipsil IP(micro)8930 microcontroller, a Linksys LAN router, and a Dell Inspiron 9300 laptop. The newly developed smart sensor was successfully demonstrated.
