The input terminal and optical receiver module of the output end connection photo-coupler of separator, the optical receiver module connect NBIoT transparent transmissions
Module, the optical transmitter module connect the input terminal of photo-coupler, and the output end of the photo-coupler connects optical cable.
By light separator by detect Signal separator come out, be decoded by optical receiver module, then with light emitting mould
The detection signal of block is matched, and there is no problem for optical cable if consistent, if it is inconsistent, it is disconnected to determine that the preceding paragraph optical cable exists
Situation is split, there will be the information of fracture to be sent to remote server by NBIoT transparent transmissions module.Design can go out in optical cable in this way
Send fracture defect warning message from trend remote service end when existing crack conditions, staff can according to the warning message,
The place that locating optical cable breaks down greatly shortens failure to must only be overhauled to the circuit of the faulty section
Discovery time and investigation the time.
Preferably, the output end of the light separator includes TCP data segment and detection signal section, the number
It is connect with photo-coupler according to transmission section, the detection signal section is connect with optical receiver module.
Preferably, the carrier wavelength of the optical transmitter module and the carrier wavelength of TCP data segment are inconsistent.Due to
The carrier wavelength of optical transmitter module is different with the carrier wavelength of cable interior TCP data segment, so will not be made to data transmission
At influence.
Preferably, further including microcontroller in the terminal box, the microcontroller connects with optical transmitter module, light respectively
It receives module, NBIoT transparent transmissions module, photo-coupler to connect with light separator, the number for being internally provided with terminal box of the microcontroller,
The NBIoT transparent transmissions module is connect by NB networks with remote server.Pass through the design of number so that staff can
Quickly positioning opposite position, to substantially increase treatment effeciency.
The utility model has the beneficial effects that：When crack conditions occurs in optical cable fracture event is sent from trend remote service end
Hinder warning message, greatly shortens discovery time and the investigation time of failure, data transmission will not be impacted.
