[Product/Solution] Distributed Fiber Optic Sensor

1. Brief introduction of the results

In view of the many problems existing in the safety monitoring scenarios of large infrastructure such as oil and gas pipelines, power facilities, bridges and tunnels, such as long measurement distance, great influence of environmental factors, low resolution, and poor real-time performance, this team has designed a high-performance distributed optical fiber safety monitoring system, which uses ordinary communication optical fiber as a sensor and signal transmission medium, and has the advantages of real-time measurement of multiple parameters such as temperature, strain, vibration, etc. at millions of points in a row.

The high-performance distributed optical fiber safety monitoring system uses ordinary communication optical fiber as a sensor and signal transmission medium, with the advantages of the world's longest 130km, millions of points in a row, the world's leading 2cm positioning accuracy, and real-time measurement of multiple parameters such as temperature, strain, vibration, etc. The product uses the communication optical cable accompanying the oil pipeline overflow and the built-in communication optical cable of the high-voltage transmission line as a sensor, which has the advantages of high efficiency, economy and ease of use.

2. Application fields

It can be widely used in the field of safety and health monitoring of large infrastructure: leakage safety monitoring of long-distance oil and gas pipelines, ice coverage monitoring of overhead high-voltage cables on land, submarine cable status monitoring, perimeter security intrusion monitoring in key areas, structural health monitoring of large buildings such as bridges, dams and tunnels, flight status monitoring of aircraft and spacecraft, and many other fields.
