And Function

The composition and function of vehicle charging system are analyzed, and basic theory of fault tree analysis method is introduced. The qualitative analysis of its reliability is carried out. Fault tree model of vehicle charging system is built, the minimum cut sets are solved and the key parts are found out. Through quantitative analysis, the occurrence probability of top event and importance of bottom event are solved, which provides theoretical basis for fault diagnoses of vehicle charging system, saves time of fault diagnoses and reduces unnecessary disassembly.

Simulation Results

Wireless communications became one of the most widespread means for transferring information. Speed and reliability in transferring the piece of information are considered one of the most important requirements in communication systems in general. Moreover, Quality and reliability in any system are considered the most important criterion of the efficiency of this system in doing the task it is designed to do and its ability for satisfactory performance for a certain period of time, Therefore, we need fault tree analysis in these systems in order to determine how to detect an error or defect when happening in communication system and what are the possibilities that make this error happens. This research deals with studying TETRA system components, studying the physical layer in theory and practice, as well as studying fault tree analysis in this system, and later benefit from this study in proposing improvements to the structure of the system, which led to improve gain in Link Budget. A simulation and test have been done using MATLAB, where simulation results have shown that the built fault tree is able to detect the system’s work by 82.4%.
