An Automated Real-Time Instrumentation System for Biological Research (BIONESS, LHPR-20)

A network of instruments and computers has been created for the evaluation of physical and biological parameters in real-time or autonomously. It provides command, control, communications and intelligence functions tallored to the needs of biological sampling. The system evolved to its present operational status through a process of close colaboration between engineers and biological research scientists. A suite of instruments for the measurement of pressure, temperature, conductivity, flow, chlorphyll, fluorescence, and vehicle attitude are discussed in the context of remote monitoring. The activity control of the sampling mechanism and cameras by the undersea computer is outlined. An important component of the system is the high reliability communications data path from ship to vehicle; the physical data link as well as the communications protocol will be presented. A detailed outline of the system design, particularly the computer architecture, will show the use made of such features as: a multi-mode system kernal, a computer network with closely and loosely coupled components, and multi-leveled interprocessor communications. Finally, the process by which the scientist interacts with the engineer to produce a system of this complexity will be examined. The design of creative scientific tools necessitates a unique collaborative effort; we will present our views in the light of this particular experience.
