specific Embodiment approach

[0032] Specific implementation, combined with Figure 1 to Figure 3 Describe this embodiment, the method for predicting the insulation resistance of an optical cable protective sheath to ground, the method is implemented by the following steps:

[0033] Step 1, using an ohmmeter and a temperature sensor to respectively collect the insulation resistance of the optical cable protective sheath to the ground and the temperature of the optical cable protective sheath, and obtain the data of the insulation resistance of the optical cable protective sheath to ground and the temperature data of the optical cable protective sheath;

[0034] Step 2: Use the Kalman filter algorithm to denoise the data of the cable protective sheath-to-ground insulation resistance and the temperature data of the optical cable protective sheath obtained in step 1, and obtain the denoised optical cable protective sheath-to-ground insulation resistance data and the optical cable protective sheath temperature...

Abstract

The invention relates to an optical cable fault prediction method based on temperature and resistance, and relates to the technical field of optical cable communication state prediction, solving the problems that the current method only can process the occurred faults in the optical cable line and cannot analyze the grounding insulation resistance value of an optical cable protection sleeve. The optical cable fault prediction method based on temperature and resistance can predict the grounding insulation resistance of the optical cable protection sleeve through an improved Gauss Wolf Pack Algorithm-Extreme Learning Machine (GWPA-ELM) prediction algorithm, can predict the temperature of the optical cable protection sleeve through a difference autoregression moving average model (ARIMA) algorithm, and can evaluate the state of the optical cable protection sleeve through the predicted resistance value and temperature. The optical cable fault prediction method based on temperature and resistance can predict the possibly occurred fault of the optical cable in the future, and can make maintenance strategy in advance.

Description

technical field [0001] The invention relates to the technical field of optical cable communication state prediction, in particular to a method for predicting the insulation resistance value of an optical cable protective sheath to ground. Background technique [0002] At present, the optical cable is composed of a cable core and a sheath, and is mainly divided into two types: oil-filled and air-filled. At present, most of the optical cables laid in our country are oil-filled. The so-called oil-filled optical cable is filled with special ointment in the cable sheath to prevent the intrusion of water or water vapor, thereby protecting the optical cable and preventing the transmission characteristics and mechanical strength of the optical cable from deteriorating or being damaged. The optical cable sheath is an important barrier to directly prevent water or water vapor from entering the optical cable, so as to protect the ointment and fiber core performance from water or water...
