| Abstract: | Aiming at the speed measurement problem of the contra-rotating propeller of the underwater ve- hicle, the paper analyses the requirement of function and performance. C8051 F020 single-chip micropro- cessor, two Hall sensor probes, double color digital tube, phase discriminator and buzzer are used to build hardware circuit. The interface of RS-485 and Joint Test Action Group （JTAG） are reserved. To improve the precision of the measurement, the alterable M/T method is adopted. The main software and interrupt service routine flow are given. The functions of speed meter, contra-rotating discriminating, display and a- larm are fully realized. The experiment test proves that the speed meter we designed can accomplish all functions the overall design required. |
