| Abstract: | The measure device of engine instantaneous rotate speed based on VxD is composed of magneto- electricity sensor, signal adjusting circuit, fast data acquisition card, PC and data processing module. Pulse signal of gear wheel rotating generated by magnetoelectricity sensor was adjusted into rectangular pulse by adjusting circuit. The data acquisition card controlled by VxD gathered rectangular pulse, and gathered data sent to PC. Sampling point number of every pulse cycle, instantaneous pulse frequency and period was gained with program operation. |
