| Popis: | The aim of the work is to create a simulation model of the transceiver path of the electronic module using various application programs and conduct a comparative analysis of the results. Simulated electronic modules (EM) form the basis of the local navigation radio engineering system used for autonomous navigation of moving objects, including automatic traffic control systems. As you know, the development process of such systems is largely determined by the choice of the carrier radio frequency and the type of used radio signals. To optimize system engineering and circuit solutions, it is advisable to apply the method of simulation modeling. Currently available computer-aided design systems allow you to use the interactive design mode and simulate electronic systems in conditions close to the real working conditions. The simulation model of the transceiver path was created using two graphic programming languages - Simulink and LabVIEW, as well as using circuitry and system modeling programs. In addition, modules for collecting and processing data can be used in the model, which allows to compare the results of modeling and the results of physical research of the object in one environment. Thus, the user gets the opportunity to visualize all the conversion processes that take place in the simulated system, as well as measure the parameters of the system units and determine the signal requirements and evaluate the influence of various factors on the behavior of the system. The construction of the model involves its use, at the level of macro models component, and at the level of circuit analysis. Separately, the possibility of combining data from the results of experimental research and the results of modeling a prototype is considered, in addition, it is possible at the software level to use powerful and flexible devices (for example, USRP-2945 and USRP-2955) for collecting and analyzing radio signals. The user has a tool to improve the quality and reduce the duration of the project work. The result of the work is a closed-loop model of EM functioning in terms of determining the signal delay proportional to the distance from the interrogator to the transponder. |
