A positional orientation device for distributed fiber sensing system

The utility model relates to an optical fiber sensing technical field specifically is a positional orientation device for distributed fiber sensing system, including a plurality of transverse orientation optic fibre and longitudinal register optic fibre, a plurality of transverse orientation optic fibre are frame shape with longitudinal register optic fibre, and cruciate fixation just of each other installs signal receiver at cross section between them, signal receiver receives the output signal who comes from transverse orientation optic fibre and longitudinal register optic fibre, and carrytransmitting signal to the controller, the controller still includes ranging module and data analysis module, the signal is carried behind ranging module's calculating and data analysis module's dataanalysis to data and is derived the module. The utility model discloses a simple optical fiber array stay knot constructs, and the scene of going on that can be very convenient is installed, is dismantled, is removed, and it c
