Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1: the present invention includes displacement transducer, vibration transducer, data acquisition unit, central processing unit, alarm, LAN server, LAN (Local Area Network) monitoring main frame, wide area network server, remote monitoring main frame and fault diagnosis device, described displacement transducer and described vibration transducer are installed on the both sides of the main shaft of described aerogenerator, the signal output part of described displacement transducer is connected with the displacement signal input end of described data acquisition unit, the signal output part of described vibration transducer is connected with the vibration signal input end of described data acquisition unit, the signal output part of described data acquisition unit is connected with the monitor signal input end of described central processing unit, the alarm signal output ends of described central processing unit is connected with the signal input part of described alarm, described central processing unit is connected with described LAN (Local Area Network) monitor by described LAN server, described central processing unit is connected with described fault diagnosis device with described remote monitoring device respectively by described wide area network server.
The vibration that equipment produces in operational process is all by a series of transmission, finally pass to the surface of equipment, therefore, in the surperficial placement sensor of gear case, carry out signals collecting, the layout of measuring point should make the bang path of signal short as much as possible, to obtain signal more clearly.
Wind turbine is in operational process, engagement between gear and the rotation of axle all can produce vibration, these vibrations are delivered on bearing by rotating shaft, and bearing is because self rotation also can produce vibration, because bearing is directly connected with housing, so vibration signal is finally delivered on the housing of gear case, so, we can install vibration transducer by the bearing portion on gear box casing, gather the vibration signal of gear and rolling bearing.By after data acquisition unit Information Monitoring after central processing unit is processed, be divided into local area network signal and wide area network signal, wide area network signal is realized long-range diagnosis and monitoring.
