Abstract
A control system, to regulate CO2 in a plant growth chamber, based on distributed processing and a multi-tasking operating system is described.
CO2 controls are based on a model of plant photosynthetic light response.
Parameters in the model that change through time are automatically evaluated and updated on a "daily" basis.
The system demonstrates how separation of the processing tasks facilitates sophisticated programming.
Results in terms of the quality of controls achieved are favorable.
CO2 controls are based on a model of plant photosynthetic light response.
Parameters in the model that change through time are automatically evaluated and updated on a "daily" basis.
The system demonstrates how separation of the processing tasks facilitates sophisticated programming.
Results in terms of the quality of controls achieved are favorable.
The importance of distributed processing and multi-tasking to the application of data analysis, simulation models, and expert systems in "real-time" environmental controls is discussed.
Low cost hardware and supporting software is quickly becoming available and the challenge will become practical implementation of straight forward ideas.
The general conclusion is that practical application of such systems can be expected in the near term.
