The Research Of On-Line Moni-toring On Chief Axis Of Single-Roller Crusher At Sinter Machine

This thesis comes from a practical industry task named "The system of on-line monitoring on the chief axis of single-roller crusher in the NO.2 workshop of sinter factory,WuHan Iron and Steel Group Corporation." On the base of analyzed the actual on site problem of the single-roller crusher in sinter factory at present, and combining the development of toque sensor, a kind of non-contact toque sensor has been turned out, which responded the production process and represented modern technology level. According to the recent progress of Computer Aided Test (CAT), the Virtual Instrument (VI) technology has been applied when designed the measure system. First, this paper expatiated the main principle of torque measure and Computer Aided Test technology, which provided theoretical basis for the torque sensor design and the system of no-line monitoring design. The next in order, this thesis studied and manufactured the hardware support kit for the task of on-line torque measure. On the one hand, according the design principle of torque sensor, this paper researched the non-contact torque sensor, which base on the theory of electric resistance strain and the rotation transformer and could satisfied the request of our project as well as the condition of the producing process .On the other hand, the modulation method of torque signal has been solved before the signal was input to the industry computer, therefore, solved the problem of signal transfers. The key for the VI technology is the software, so, in succession, the paper lucubrated the software foundation of VI. In this section, established a software for on-line measure with graphical programming environment --LabVIEW which oriented instrument and measuring-controlling process. This software consisting the module of data acquisition and the module of data manage. At last, the paper introduced the necessary assistant work for on-line measure, which includes torque sensor calibration, installation and adjustment of measure system, etc.In this research, the VI technology was applied in the on-line measure of sinter equipment for the first time. It will give some reference for the further research aftertime.
