OpenRVDAS

Overview

The Open Research Vessel Data Acquisition System (OpenRVDAS) is a software framework used for building custom data acquisition systems (DAS). OpenRVDAS target audiences are oceanographic research vessel operators and operators of other science-related platforms that have the need to record streaming data. OpenRVDAS is capable of reading data records from serial ports and network-aware sensors, optionally modifying those data records and streaming either the result to one or more destinations, including logfiles, network ports, databases, etc.

OpenRVDAS is designed to be modular and extensible, relying on simple composition of Readers, Transforms and Writers to achieve the needed datalogging functionality.

Motivation

The primary purpose of an oceanographic research vessel is to gather data from sensors. Oceanographic research vessels carry a combination of oceanographic, meteorological and other specialized sensors. Some of the more complex sensors (i.e. ADCP, Multibeam, imaging systems) include specialized data acquisition systems tailored to the particlular sensor. Many simpler sensors, however, can simply stream data values over a network port or serial connection.

At present there are limited options for operators wishing to store and display data from these simple sensors. This task is commonly referred to as underway data logging. Most research vessel operators rely on closed-source, solutions (i.e. SCS, WinFrog) or on dated datalogging systems (i.e. dsLog, LDS) for underway data logging. Both options provide limited support mechanisms, thus bugs are slow to be resolved and feature requests are slow to be implemented.

OpenRVDAS hopes to provide an alternative underway data logging solution that is defined, developed and maintained by the global oceanographic research community.

OpenRVDAS recognizes that each ship is different, that each ship has a unique set of sensors and that each ship has a unique way of operating. With this understanding, OpenRVDAS does not try provide a turn-key, one- size-fits-all solution but instead provides research vessel operators with a modular and extensible toolset for developing and deploying a custom underway datalogging solution tailored to the vessel's individual needs.

DISCLAIMER: THIS CODE IS EXPERIMENTAL AND STILL UNDER DEVELOPMENT. IT SHOULD UNDER NO CIRCUMSTANCES BE RELIED ON, ESPECIALLY NOT IN ANY APPLICATION WHERE ITS FAILURE COULD RESULT IN INJURY, LOSS OF LIFE, PROPERTY, SANITY OR CREDIBILITY AMONG YOUR PEERS WHO WILL TELL YOU THAT YOU REALLY SHOULD HAVE KNOWN BETTER.

Documentation

Most OpenRVDAS documentation is gathered in the docs/ subdirectory of this project. We recommend beginning with OpenRVDAS Introduction and Overview, Introduction to Loggers and Controlling Loggers to get started.

Installation

OpenRVDAS is written primarily in Python 3.[^1] There are currently installation scripts for CentOS 7, Ubuntu 16 and Ubuntu 18, but it may be manually installed on other systems. Please refer to INSTALL.md for details.

Ship/Organization-Dependent Code

Please see the local/README.md file for conventions on where and how to organize your institution's configuration and definition files.

[^1]: Recommended version of Python is 3.6 or higher, but most listener code has been verified to run on 3.5 and higher. Server code such as logger_runner.py and logger_manager.py may experience problems on 3.5 due to changes in the async module.

You can’t perform that action at this time.
