The tilting pad bearing monitoring system collects many types of data and has super-multiple acquisition channels.It is difficult to realize arbitrary selection of channels.To solve this problem,a method based on polling enumeration was proposed,in which circular index and enumerated condition structure were combined.LabVIEW platform was used to implement the algorithm.Through experimental verification,this method can be used to realize arbitrary selection of acquisition channels,and the corresponding data storage is also very convenient,which is convenient for data acquisition and analysis of a single bearing block.
