Abstract

Background. Digital code – time interval converters are used in remotecontrolled Autonomous information and control systems for counting the time of remote action, deceleration, and self-elimination. The rapid change in the environment in which the system operates requires a reduction in the time it takes to enter task data, in particular, the time of remote action. Reducing data entry time by increasing the data transfer rate is limited by the bandwidth of the communication line. This raises the challenge of finding new ways to reduce data entry time.
Materials and methods. Continuous and discrete models of nonlinear transformation with the possibility of their implementation by computing means of Autonomous information and control systems are considered.
Results. It is proposed to reduce the time and length of the code to introduce data with a discreteness, the value of which is a constant relative to the set time of action. It is shown that a constant value of the relative discreteness of data input is provided by nonlinear code – time interval pre-formation. For a continuous transformation model, this is an exponential function; for a discrete model, it is an exponential function. The possibility of simplifying the implementation of a nonlinear transformation by replacing exponential and exponential functions with their representations of the Taylor series with a limited number of elements, as well as interpolating or approximating polynomials of different orders, is analyzed. Ensuring high conversion accuracy is achieved by using piecewise linear or piecewise quadratic conversion.
Conclusions. Using non-linear conversion of the digital code to the time interval allows you to reduce the length of the binary digital code and reduce the time for entering the task data. In the example above, the length of the digital code was reduced from 16 to 12 bits when using a non-linear transformation.
