Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
Model: Multi-core Cable System Offshore Structure Measuring Device

Dynamic measurement of the behaviour of marine structures
This is a measurement system for field demonstration tests of caissons built at sea.
We will introduce the three methods of maritime observation unmanned acquisition method, submarine multi-core cable method, and optical power combined submarine cable system.

Feature

【Unmanned Acquisition Method for Maritime Observation】
● Data acquisition is possible unmanned and fully automatic
● Observation can be divided into two measurement systems, dynamic and static
● Observation can be started at a preset wave height level, and interval measurement is also possible
● Observation waveform can  be monitored
● The measured data is stored on a digital storage medium. Dynamic observation data can be stored and retrieved in a non-volatile storage device for about one month. Static observation is stored in flash memory for each observation
● The power supply of the system control device that requires constant power and the power supply of the observation device are configured in separate systems, and the charging of each uninterruptible power supply is supplied by a generator as necessary
● There is a check function related to the system and power supply, and an alarm can be output to the outside in the event of an abnormality [Optical power combined submarine cable system]
● Optical power composite submarine cable is adopted, and the power supply is supplied to the monitoring station by this, so that cable laying work costs can be kept low and at the same time free observation can be observed regardless of power supply capacity
● Automatic observation and manual observation selection commands can be given from the land monitoring station, In addition, it is possible to automatically start measurement when a high wave above the preset wave crest value arrives [Submarine multi-core cable method]
● The bridge power application method adopts a constant current method, so accurate measurement is possible
● The observation mode is wave height observation, constant time interval, and hourly observation, Equipped with an arbitrary observation mode, etc.
● Static test is a small digital measuring instrument, dynamic test uses
signal conditioner and digital data recorder
● Sliding test always stores 1 hours of sliding data on a hard disk so that no sliding data is missed. In addition, important data can be backed up to a digital data recorder
● Data transmission via telephone line allows important data to be monitored and printed at the management office, making it possible to respond quickly to observations.
