Abstract：The bearing vibration monitoring of induced draft fan is more complex,and in most cases,staff are required to pa-trol the site constantly to ensure its normal work.In order to solve this problem,an online monitoring system of induced draft fan bearing based on DSP is designed,which not only includes the horizontal and vertical vibration of the driving end and the non-driv-ing end of the induced draft fan,but also includes the temperature of the bearing.Through the real-time acquisition of on-site vibra-tion and temperature signals,after the processing of signal processing circuit,it is transmitted to the DSP,through the DSP using RS-485 communication bus real-time transmission to the top bit,to provide staff with a simple and easy to understand the field sig-nal.The test results show that it can reflect the working condition of the induced draft fan bearing in real time,quickly and accurate-ly.
