Akamina's Data Acquisition System


The Akamina Data Acquisition System is a high speed data acquisition system designed for use in hydrodynamic model studies. The system consists of the ADQ-1000, a networked server that acquires data and WaveGen-Studio, a user interface client. The ADQ-1000 includes acquisition hardware, power supply and interface connectors in a rack-mountable chassis. A fully loaded system supports 32 analogue input channels and two CAN Bus interfaces, each of which can support up to 30 AWP-300 wave height gauges. The analogue input channels are configured for differential input with 16-bit analogue-to-digital converters for optimal measurements. The system samples all input channels at 1000 samples per second



WaveGen-Studio provides the user with a graphical interface to the ADQ-1000. It is designed to run on Windows compatible PCs. The client allows the user to select channels for acquisition, start and stop acquisition, calibrate sensors and export acquired data in convenient csv format. Advanced features such as a strip chart recording allow the user to view raw data in real time.









Akamina Wave Height Gauge





Akamina supplied a system of 15 waterproof wave height gauges to the Port and Airport Research Institute (PARI) in Tokyo, Japan. The system is used for directional wave measurement on their Hiratsuka Tower (close-up view ).


WaveGen-Studio and the ADQ-1000 provide a complete solution for your data acquisition needs. Akamina's system uses a network of connected servers for control capabilities and the acquisition of data which is controlled by WaveGen-Studio.

Akamina has the exclusive license to GEDAP - Generalized Experiment control and Data Acquisition Package - developed by the National Research Council Canada. GEDAP is a well-proven, complete software solution for physical modelling in hydrodynamic laboratories. GEDAP brings wave synthesis and wave data analysis with sophisticated plotting capabilities to the Akamina data acquisition and control offering.



Akamina completed the design, fabrication, installation and commissioning of the new portable wave generator in the Large Area Basin at the National Research Council Canada . This system features a portable, modular design consisting of 9 modules with 8 piston-mode segments per module. The drive system includes a regenerative power supply with an inverter to drive a transmission system that includes a synchronous motor, lead screw and rotating ball-nut. The controller and the servo drives for the 8 segments in a module are connected on a SERCOS III loop. The control system was featured in the "Sercos Makes Waves" article on the Sercos.org website.

The wave generator control system provides support for active wave absorption (reflection compensation) for both unidirectional and multidirectional waves. Other enhancements include improvements in sidewall reflection techniques and second-order wave generation.

In 2016 Akamina completed the design, fabrication, installation and commissioning of a 48-segment facility for the Offshore Technology Research Corporation at Texas A&M in College Station, Texas, USA. This was an upgrade project in which the mechanical and hydraulic drive subsystems were already in place. The upgrade included the design and fabrication of custom control hardware and software as well as data acquisition hardware and software. Installation, integration, commissioning and training were carried out on-site in College Station. Akamina's WaveGen-Studio with GEDAP software were supplied for wave generation and data analysis.


Akamina completes the design and the successful installation of 56-segment wave generator control system upgrade. The upgrade included custom control hardware and software as well as data acquisition hardware and software. This work was done for EDF - Laboratoire National d'Hydraulique et Environnement (EDF-LNHE) in Chatou, France.
