<P>PROBLEM TO BE SOLVED: To provide a system having the advantages of low energy consumption, long working time of a rotating shaft module, less time for changing batteries, simple structure and reliable communication. <P>SOLUTION: A fixed module Mf is arranged on a fixed device. The fixed module Mf is wirelessly connected with a rotating shaft module Mm through optical signal transmission and reception. The method includes the following steps: the data collected by a sensor 7 are subjected to A/D conversion firstly for converting analog signals into digital signals, and buffered by an MCU to drive an optical signal emitter 6 to emit optical signals; an optical signal receiver 4 receives the emitted optical signals, and converts the emitted optical signals from the optical signal receiver 4 into electrical signals which are buffered by the MCU and converted into standard serial port signals; and the standard serial port signals are uploaded to a computer for monitoring. <P>COPYRIGHT: (C)2010,JPO&INPIT |
