Abstract

To detect distributed deformation angles in real-time for large measuring and weapon devices mounted on large ships

as well as to improve the ability of controlling and real-time monitoring to each measurement point

a measuring system for the distributed deformation was realized based on an embedded system.The hardware design

the realization of software and corresponding algorithm were explored. Firstly

comparing to the previous measurement method with distributed sampling

central obtaining data and calculating data

a new model of distributed measurement was proposed. And Simple Network Manegement Protocol(SNMP) was selected to realize the remote control of all devices. Then the structure of the protocol and its composition were introduced. A hardware platform was designed for the distributed deformation devices of each measurement point based on ARM+DSP+FPGA structure. After that

the software was developed on the WinCE operation system and the flow process was discussed. Finally

the experiment of system was executed both on deformation measurement and SNMP control. Experimental result shows that the device can obtain the precision within 5" without network congestion problems caused by image acquisition as the previous devices. And the capability of extending and administrating has been enhanced.
