On cable, the end connection optical fiber grating sensing demodulator of optical fiber, optical fiber grating sensing demodulator passes through FPDP and computer
It is connected.Using optical fiber grating sensing demodulator, while monitoring multiple fiber-optic grating sensors, various types of signal is demodulated, then
Demodulated signal is effectively analyzed using computer, while demodulated signal is compared with preset value, if beyond pre-
First setting value, then send early warning signal.
The utility model has the advantage of:The monitoring system solve over will manually with unmanned plane patrol transmission cable
Inconvenience, and electrical sensor easily disturbed by electromagnetic field, it is impossible to the drawbacks of being used in this kind of occasion of transmission cable.Use
