Abstract
The paper describes the technology of representing informative dynamic parameters in interactive systems for monitoring and managing complex scientific and technical objects. It allows to give the most complete and adequate view of the state of the managed system, and at the same time provide the human-operator with the ability to perceive the information presented in terms of making sound and effective operational solutions.
It is proposed to construct a class of images similar to the known dynamic spectrograms, but with a wider representation capabilities. These composite images are formed in two stages. At the first stage, the signal segments are described as functions of one variable (diagrams). Here, the expansion of the presentation capabilities is achieved by applying various descriptions (spectrogram, histogram). Diagrams are represented as a vertical segment. Amplitude is encoded by the brightness of the screen point. At the second stage, compilation of images from the column-descriptions of a certain type is performed, that is, a consecutive arrangement of columns on the screen. Here, the extension of presentation capabilities is also based on the introduction of diversity - the use of different types of compilation. For example, the abscissa value (that is, the column number) corresponds to the value of the determining parameter of the signal source (the degree of wear of the cutting tool, the magnitude of the load, the output power). Examples of the representation of various parameters are given. The proposed class of composite images allows you to compactly represent large data sets.
The human-machine interface can be designed to represent a wide variety of signals. Therefore, providing not only compactness, but also the efficiency of presentation requires a wide variety of descriptions and types of compilation. They should be selected depending on the parameters and signals analyzed. With a successful choice, visual analysis is greatly facilitated, and it becomes more productive.
Keywords: scientific visualization, dynamic parameters, composite images, color coding, interactive mode.
