| Abstract: | The paper presents an on- line condition monitoring and diagnosis system based on embedded system, which can improve the efficiency and reliability of hydraulic system for engineering machinery. The system is low in cost and high in reliability due to PC104 embedded computer. By means of taking the signals from machinery, it combines the expert system and neural network to complete the alarming and fault diagnosis of hydraulic system. It also expounds the hardware and software configuration and working process of the system. |
