It has been found that the success of the Space Station engineering development, the achievement of initial operational capability (IOC), and the operation of a productive Space Station will depend heavily on the implementation of an effective automation and control approach. For the development of technology needed to implement the required automation and control function, a contract entitled 'Automated Subsystems Control for Life Support Systems' (ASCLSS) was awarded to two American companies. The present paper provides a description of the ASCLSS program. Attention is given to an automation and control architecture study, a generic automation and control approach for hardware demonstration, a standard software approach, application of Air Revitalization Group (ARG) process simulators, and a generic man-machine interface.

The automation system features a hierarchical and distributed real-time control architecture which places maximum controls authority at the lowest or process control level which enhances system autonomy. The ASCLSS demonstration system pioneered many automation and control concepts currently being considered in the space station data management system (DMS). Heavy emphasis is placed on controls hardware and software commonality implemented in accepted standards. The approach demonstrates successfully the application of real-time process and accountability with the subsystem or process developer. The ASCLSS system completely automates a space station subsystem (air revitalization group of the ASCLSS) which moves the crew/operator into a role of supervisory control authority. The ASCLSS program developed over 50 lessons learned which will aide future space station developers in the area of automation and controls..

By using state of the art, commercially available technology, these operations can be automated to reduce costs and improve mission success. In addition, the technology allows remote launch monitoring and personnel reductions at the launch site. Today\u27s industrial work stations, computers, communications hardware, and data bus equipment, in use throughout the process control industry, can be integrated with existing avionics and organized into a modern avionics architecture. Such an architecture could replace the current launch site, push button implemented, command and control and the plethora of strip chart performance monitoring systems. The new avionics architecture defined by Honeywell features a user friendly electronic data base/archiving system coupled to a realtim...

It is argued that present-day industrial work stations, computers, communications hardware, and data bus equipment can be integrated with existing avionics and organized into a modern avionics architecture. A novel avionics architecture features a user-friendly electronic data base/archiving system coupled with a real-time command/control capability. It is designed to automate much of the launch operations and significantly reduce costs. Benefits of commercial off-the-shelf products are discussed.
