Multi-tasking operating system and speedy solid state media
The Seanet SCU is a multi-tasking control unit running under Microsoft Windows™ Embedded, which is installed on an internal solid-state disk. The Seanet SCU allows for complete control of the software using a Remote Access Terminal (RAT). This is an ergonomically designed device which either neatly clips onto the front of the unit or is used as a remote via a cable. The built in minijoystick on the RAT provides a useful tool for carrying out range and bearing measurements on sonar data.
To ensure the Seanet SCU provides a reliable, rugged and easy to install unit it has been designed as a robust 19″ 3U rack mount unit with ruggedly mounted sub assemblies for maximum reliability.
A high speed 156kbit·s-1 communication system is used within the Seanet SCU, allowing a full suite of Tritech sensors to be operated over a single twisted pair or, by using the Tritech MultiComm Junction Box, over an RS232 or fibre optic interface.
Each device connected to the Seanet SCU runs, in real time, in its own on screen window. The monitor display may be varied to show single or multiple windows and this can be altered at any time during normal operations. This multiple sensor capability provides obvious cost benefits as well as reducing the space requirement for consoles in the control room.
Using the multi-device capable Tritech Seanet Pro software (which is pre-loaded onto the SCU) it is possible to integrate systems with both Gemini and SeaKing devices, offering a single point of control for all the sensors on the ROV.
