Problems solved by technology

The biting of mice and other animals is one of the important hazards to the safety of optical cables and cables. Especially for optical cables and cables in pipelines, animals such as mice often bite the outer protective sheath, or even bite the cable core, causing the communication of the optical cable to be interrupted or Cable insulation failure will also cause some accidents or major economic losses
[0003] In the existing technical solutions, there is an armored layer used to prevent mice from biting, but the outer protective cover will still be bitten, causing the armored layer to be exposed, gradually rusted and destroyed; there is also capsaicin applied on the outer protective cover Or add capsaicin to the outer protective cover to stimulate mice and play a role in repelling mice, but it will affect the health of construction workers during installation, and the effect of repelling mice will gradually decrease as time changes; some also use infrared detection However, if the pipeline has a turn or there are objects such as cables that block the mice, there is a problem that the mice cannot be found; therefore, it is necessary to invent a long-term effective and no blind spot. The unique method of repelling rats can effectively prevent the optical cables and cables in the pipeline from being damaged

Embodiment 2

[0039] refer to figure 2This embodiment differs from the above embodiments in that the ultrasonic rat repelling unit 200 for expelling rats further includes an optical fiber vibration detector 202 for detecting vibrations of the cables 102 and 103, and data processing for analyzing the detected vibrations. Module 203, a central system 204 that transmits control signals to the rat repelling assembly 201, an electromagnetic coil 201a that takes electricity from a cable inductively, a battery 201b that provides power to the rat repelling assembly 201, and a control module that controls the state of the speaker 201d 201c, a speaker 201d that emits sound to expel mice, a signal receiver 201e that receives control signals sent by the central system 204, and a casing that protects the expelling assembly 201.

[0040] Further, the vibration of the cable 102 and the optical cable 103 is detected by the optical fiber vibration detector 202 in the ultrasonic mouse repelling unit 200, th...

Embodiment 3

[0045] like image 3 The shown method for repelling rodents in pipelines based on underground optical cables and cables is used for a rodent repelling system in pipelines based on underground optical cables and cables in Embodiment 1 and Example 2, and specifically envelops the following steps:

[0046] S1: A core optical fiber in the optical cable 103 is connected to the optical fiber vibration detector 202 to monitor abnormal vibration signals in the pipeline 101;

[0047] S2: The optical fiber vibration detector 202 collects abnormal vibration signals in the pipeline 101, and organizes the measured vibration data into a two-dimensional array X according to time-space, and its element X(i, j) refers to the spatial point i at time j. Vibration signal strength;

[0048] S3: The reasons for the occurrence of vibration signals obtained in the daily data operation and maintenance process. According to the occurrence time, stop time and spatial scope of the event, the vibration e...
