Design of Mmulti-channel Temperature Measurement System for Large Motors Based on C8051F020

The real time monitoring system that functions to visualize and intellectualize the process of temperature rising in the critical parts is studied and finally put into practice with the aid of digital process- ing device C8051F020. It is of great help while inaccurate and inconvenient temperature rising monitoring or something happens to the critical parts of giant motor. The design of this system provides specific information, in the aspects of temperature sampling circuits, passage-optional circuits, V/F switching circuits, communication circuits and the designing process of system software. It is testified after experiments that this system performs well in accurate measuring, simple operating and convinient usage, and it fully meets the need of practical monitoring. As is mentioned above, it can provide a guarantee for the reliable operation of the large motor in the longrun.
