Embodiment
The embodiment of the content of the invention is illustrated below in conjunction with the accompanying drawings.
A kind of mine conveyer carrying roller malfunction monitoring positioning as shown in Figure 1 and warning device, formed comprising three parts：
Information acquisition module 1, information analysis processing module 2, real-time monitoring module 3；Information acquisition module 1 is located at the work of mine conveyer
Make in environment, be connected with information analysis processing module 2, information analysis processing module is connected with real-time monitoring module 3；Information gathering
Module 1 includes sensor fibre, driving power, semiconductor laser, coupler, amplifier, optical-electrical converter, data acquisition card；
Sensed using the sensor fibre laid along carrying roller (conveyer belt) both sides, be respectively in by support in capture conveyer belt operation
Vibration information after roller is along time and the Two dimensional Distribution situation in space, by measured obtained fiber-optic vibration curve data temporally
Axle forms the state diagram that oscillation intensity is represented by gray value, when the abscissa of the state diagram is fiber lengths information, ordinate is
Between length information, and send information analysis processing module 2 to；Signal analysis and processing module 2 is to defeated according to the information collected
Send band to operate in state diagram corresponding during fault-free carrying roller and carry out time-domain analysis processing, carried out using the technology of adaptive-filtering
Denoising, to improve system signal noise ratio, obtain the vibration performance frequency of the carrying roller under non-failure conditions.Repeat the above steps, establish
Carrying roller vibration data storehouse, carrying roller characteristic frequency information is stored in carrying roller vibration data storehouse；When in carrying roller vibration data storehouse
This group of data markers are then that observation state is stored in database in default allowed band by the difference of carrying roller vibration performance frequency
In, it is that carrying roller goes wrong if difference is not in default allowed band, is that alarm condition is stored in carrying roller by this group of data markers
Vibration data storehouse, and the information transfer that carrying roller is gone wrong is to real-time monitoring system；Real-time monitoring module 3 is filled by onsite alarming
