Description

technical field [0001] The embodiments of the present invention relate to a line optical cable monitoring technology, and in particular, to an on-line monitoring system and method for a circuit optical cable. Background technique [0002] Due to the wide distribution of transmission lines in my country, the area covered by power grid construction is complex and changeable, and the transmission lines have the characteristics of large dispersion, long distance, and changeable weather conditions. Therefore, the inspection and maintenance of transmission lines in many areas of my country has become a major problem to ensure the operation of the power grid in this area. In order to effectively reduce the maintenance cost of IOPPC optical cable line and realize 24-hour real-time monitoring of IOPPC optical cable line, remote monitoring of IOPPC optical cable line body, surrounding environment and meteorological parameters has become a key issue to be solved urgently.

Problems solved by technology

[0003] However, the existing IOPPC optical cable line online monitoring method has the following problems: 1. The anti-interference performance of the sensor is poor. Due to the influence of the measurement environment, the sensor is easily disturbed by the magnetic field, resulting in unreliable measured data.

2. The compensation performance of the sensor is poor

3. In the harsh environment, manual monitoring is required, which consumes a lot of manpower and material resources, and it is difficult to meet the real-time requirements
