The product concept is based on increasing demand for the information construction of the pipeline; increasing data transmission capacity; fibre-optic communication has become the primary means of communication of the pipeline data; the security of the cable as a sensor directly affects the security of communications; and thus the safety of the pipeline's transmission. Therefore, effective management and rapid deployment of the oil and gas pipeline communications cables is important. Problems are solved by the lack of clarity in the route of the cable; the complexity of the route; the complexity of the route; the passage of the farm, the village, the river between the mountains and the river; the changes in the environment and the impact of the construction of some people; the frequent movement of the route; and the fact that some of the circuits are not clear for historical reasons; the lack of clarity in the information; or even the loss of it; the lack of clarity in the route; and the fact that the cable should be managed with great distress. Cable failure is difficult to locate; traditional cable online monitoring systems or OTDR can only measure the length of the cable failure point; it is impossible to locate the location of the failure point; it is maintained; it often requires manual excavation of multiple pits (usually five to eight for a failure point); failure points are performed; not only are they costly; but it is also lengthy. Cable circuits are also referred to as “optic cable failure tracker”; cable circuits are made up of three components: the smart locator-OCR smart management platform; the OCR smart management mainframe; the smart cloud platform; and handheld smart terminals. When used; host connected to fibre-optic cables in machine room (valves); maintenance of the builder ' s hand-held smart terminal; rubber-coated hammering; near the oil and gas pipeline; impact on the ground; host ' s vibrating message around the entire cable via an intelligent cloud platform

Application background; cable search + cable failure positioning (detection) with the implementation of the “broadband China” strategy; fibre-optic communication has become widespread; fibre-optic cables have spread throughout every city of the country. However, cables are mostly laid underground or in the air; the maintenance and management of big cables is a challenge. Especially when ageing, natural destruction or man-made damage causes optical cable failure; would seriously interfere with the effective functioning of the information society; and would affect information security. So rapid routing and location of malfunctions; recovery and repair in the shortest possible time becomes essential. Because of the speciality of cable laying; the length and actual geographical distance of the cable are different; when the cable malfunctions; and the length of the cable can only be measured by OTDR without informing the geographical location of the fault. Even if the fault cable can be found on the market ' s census machine, the location of the fault will take a lot of time and effort. The LFD cable failure locator; also known as the cable failure tracker; in addition to having the function of cable surveyor (otherwise, cable surveyor, cable caller, cable checker); and the function of cable failure locator. The function is to detect the location of external disturbance signals based on the double-reflective effect of fibre-optics; thus, the location and location of cable failure points is to be achieved. Engineers only have to perform undamaged disturbance of the cable; the instrument automatically detects the location of the disturbance point from the failure point; then gradually approaches the failure point and perform the same operation; then, after several tests, the fault location can be quickly located. This will significantly reduce the time required for failure recovery
