A fiber grating sensor insert, implanting system and method of an intelligent plastic pipe. A fiber grating sensors' strip-shaped insert is accurately implanted in an oblique guiding manner in the pipe's outer surface during the continuous extrusion molding process of the plastic pipe, so that temperature and strain sensors implanted beforehand in strip-shaped insert are buried in the pipe, and the sensors' survival in a bad pipe manufacturing and working environment is ensured, real-time online monitoring on parameters of the pipe such as temperature, strain, pressure and the like is achieved, the conventional continuous extrusion process technology of plastic pipes is combined with optical fiber communication technology, and the manufactured intelligent plastic pipe can achieve real-time online monitoring of temperature, strain, pressure and other parameters, and then can realize the safety early warning, fault diagnosis and automatic control of urban pipe networks, thereby effectively promoting the construction of 'smart cities'.

A composite material packaged fiber grating sensor and a manufacturing method thereof. The sensor includes a fiber grating sensor component, a composite material coverage layer, a resin package layer and a composite material substrate layer. In the sensor, a temperature fiber grating and a strain fiber grating are packaged in a composite material structure, so that the structure is light and simple, its computability with the composite material is good, the measurement accuracy is high, and the survival rate and the service life of the installed sensor can be greatly improved, the sensor component can be externally pasted on to or inter-implanted in a composite material structural part, and can be applied to the distributed online health monitoring on the structural part. The manufacturing method of the composite material packaged fiber grating sensor is simple, efficient and stable, and is suitable for rapid mass production by enterprises.
