Description

technical field [0001] The invention relates to the technical field of measurement and testing, in particular to a measurement system and method based on machine intelligence prediction multi-parameter optical fiber sensor. Background technique [0002] At present, optical fiber sensing technology can accurately sense physical quantities at a single point or a single parameter, and realize digital output of the detected physical quantities through analog-to-digital conversion. However, such parameters are to respond when the optical fiber sensor detects an error and may lead to serious consequences. At present, there is no accurate definition and model for abnormal state prediction, and abnormal detection technology is still lacking. It is urgent to integrate sensing information and knowledge Combined to improve the intelligence of the machine; at the same time, it is very difficult to sense the multi-dimensional state, such as environmental measurement, whose characteristic...
