| Abstract: | The system configuration and realization of diesel engine speed measurement is presented during the locomotive waterresistance test. The target accuracy of the signal detection circuit and measuring system are analyzed in details. It is discussed how thereal-time speed is calculated by the singlechip by measuring the frequency. The software realization flow chart is given based on AT89C2051singlechip as well as the further extended scheme of the system. Practical operations indicate the feasibility of the method. Its realizationsystem features simple operation, stable performance and high accuracy, and conforms to production requirement. |
