The high speed multispectral temperature measuring system scheme is proposed to solve the technical problem that
Abstract
the turbine blade cannot be monitored which is in high rotating speed and high temperature that are not easy to measure in China. In
this paper the software and hardware test scheme based on high speedmultispectral temperature measurement technology is put for-
，
ward the explore probe the light-splitting system the spectral photoelectric sensor system and the software system are designed
， ， ， ，
which is applied in practice. By monitoring the actual health status of gas turbine blades in real time the thermal barrier coating of
，
turbine blades is removed and the cooling channel is blocked and the other damages are effectively warned so as to prevent further
， ，
expansion of faults and reduce economic losses.
