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'.
