A Novel Visual SISO and MIMO Computer Interface for Process Production System

Computer based automation systems have found a wide range of applications in manufacturing and processing industries. To interface computer and control system, various standard industrial interfaces were used. Because of its complexity and high cost in some places, a custom model was built by a person having broad knowledge of computer and control system. Later on visual patterns based computer interfacing was introduced. This used less hardware when compared to the standard model. To further reduce its hardware complexity, in this paper, a modified vision based computer interfacing is introduced for single input single output (SISO) systems. This technique is further extended for multiple inputs and multiple output systems (MIMO). The working of the proposed interface modules were tested with the help of computer control based SISO conical liquid tank system and MIMO heat exchanger system.
