Abstract
In order to facilitate the disposition of multiple noise measuring points in a distributed manner, this underwater noise monitoring device is provide with: a processing unit in which, by using data which was acquired using optical fibers installed underwater or on a bottom of water and which indicates noise or vibration at the position of each of the optical fibers, a statistical value of the amount of noise or vibration is derived at the time and the place when/where the data was acquired; and an output unit that outputs the statistical value.
Claims16
An underwater noise monitoring device comprising:
- a processor configured to derive, by using data representing noise or vibration at each position of an optical fiber included in an optical cable installed underwater or on a bottom of water, the data being acquired by the optical fiber, a statistical value of an amount of the noise or vibration at a time and the position when and where the data are acquired;
- and
- an output circuit configured to output the statistical value,
- wherein the processor is further configured to perform processing of, based on information of the optical cable at each place, the information being input separately and related to a type of the optical cable or an installation method of the optical cable, reducing, from the amount, an influence on sensitivity due to a difference in the type of the optical cable or the installation method of the optical cable.
An underwater noise processing method comprising:
- deriving, by using data representing noise or vibration at each position of an optical fiber included in an optical cable installed underwater or on a bottom of water, the data being acquired by the optical fiber, a statistical value of an amount of the noise or vibration at a time and the position when and where the data are acquired;
- and
- outputting the statistical value,
- wherein the underwater noise processing method further comprises processing of, based on information of the optical cable at each place, the information being input separately and related to a type of the optical cable or an installation method of the optical cable, reducing, from the amount, an influence on sensitivity due to a difference in the type of the optical cable or the installation method of the optical cable.
A tangible and non-transitory recording medium recording an underwater noise processing program causing a computer to execute:
- processing of deriving, by using data representing noise or vibration at each position of an optical fiber included in an optical cable installed underwater or on a bottom of water, the data being acquired by the optical fiber, a statistical value of an amount of the noise or vibration at a time and the position when and where the data are acquired;
- and
- processing of outputting the statistical value,
- wherein the underwater noise processing program is further configured to cause the computer to execute processing of, based on information of the optical cable at each place, the information being input separately and related to a type of the optical cable or an installation method of the optical cable, reducing, from the amount, an influence on sensitivity due to a difference in the type of the optical cable or the installation method of the optical cable.
