| Abstract: | This paper introduces a frequency measurement system based on an AT89C2051 micro controller for hydroelectric generator unit. The technique of photoelectric isolation to the input/output parts and the method of alternate count to the two halves of the periodicity signals are used in the system. Therefore, the system is characterized by high reliability sensitivity of signal reaction, simple structure and wide utility, etc. Also, the system can be widely used in F V convertor, rotating speed relay and electro hydranlic governor. |
