| 针对目前的滑动轴承状态监测系统传感器在现场安装位置受限，离信号源头较远，不容易获得可靠的状态信息，
文章提出一种新型的智能轴承结构，在滑动轴承上嵌入温度、转速、振动等传感器，并在DSP上实时处理轴承的工作状
态信息。嵌入式的智能传感器安装在轴承外圈，更接近于信号的源头，因此智能轴承的传感器能获得比滑动轴承更准确
的状态信息，因DSP信号处理部件与传感器紧密配合，在实时处理信号方面更有优势。经实验验证，智能轴承比传统的
轴承状态检测系统更能有效地提取状态信息和故障诊断信息。 |
| 英文摘要: |
| Due to the limit of installation site. the sensors are far away from the signal source and the state information
can't be acquired validly. To solve this problem. a kind of embedded intelligent bearing was studied. Temperature,
speed and vibration sensors were embedded in the sliding bearings. The state information of the bearing was processed in
real time by DSP equipment. A novel structure of bearing was developed. The embedded intelligent sensors were
installed on the out ring of the bearing and approached to the signal source. So the sensors can get the signal more
validly. The DSP chip was configured just for the intelligent bearing so the signal can be processed rapidly. The result of
the experiment and simulation show that the intelligent bearing can extract the state information and diagnosis information
more valid than the tradition bearing monitor system. |
