Ultra-weak fiber bragg grating inclinometry terminal and networking method
The invention discloses an ultra-weak fiber bragg grating inclinometry terminal and a networking method, and the inclinometry terminal comprises an ultra-weak fiber bragg grating sensing module, a control circuit module, an edge calculation module and a housing. And the ultra-weak fiber grating sensing module is connected with the multi-core ultra-weak fiber grating optical cable. The control circuit module performs control and network communication, and the edge calculation module is responsible for data acquisition, storage, processing and deformation calculation. The inclinometry terminal can directly collect the wavelength change of the ultra-weak fiber bragg grating on the multi-core optical cable, obtains the corresponding strain distribution of each optical fiber in the space through edge calculation, further inverts the deformation of different positions on the optical cable relative to a reference point, and returns the deformation to the cloud platform. The terminal is low in transmission rate, small in size, low in power consumption, easy to arrange on site, capable of supporting wireless network return and solar panel power supply, and good in economical efficiency and field adaptability.
