This paper introduced a design scheme of the distributed fiber-optical temperature measurement mainframe which may be applied in the environment with slow temperature change. This scheme was based on the Raman scattering principle and used wavelength division multiplex ( WDM) , time division multiplex ( TDM) and space division multiplex ( SDM) for design, and it was suitable for the environment with slow temperature change. The test results showed that this distributed fiber-optical temperature measurement mainframe can accurately monitor the temperature and rapidly give early-warning.
