Abstract
A pulse signal generator was designed
which was the test section in vibration measurement system for high-speed rotating blades.It could simulate multi-channel pulse signals from on-site optical fiber sensors in real time to test and verify the reliability of software algorithm in system.The mathematical model for rotating blades was built up
and according to the selected parameters of blade vibration
the pulse’s generating time of every sensor could be obtained by calculation.The hardware design based on ARM and FPGA was implemented
in which ARM is used for peripherals control and FPGA is used for calculating results and output pulses.The device could generate accurate pulses in the system
which satisfied the requirement of high-precision and high-speed.Moreover
the device was portable and had enough adjustable range by inputting parameters through keyboard or RS232.
