Special Issue Information

Dear Colleagues

In recent years, there has been an explosion in the development of electronic systems installed in different types of vehicles, and diagnostic systems, in particular, have been at the centre of several important developments in both civil and defence applications. New technologies, such as multisensory data fusion, big data processing or deep learning, are changing the quality of application areas, improving the sensors and systems used.

Technological progress, as well as the rich functionality of electronic systems used in equal types of means of transport (cars, trains planes and ships) means that we are dealing with many types of devices made with different technologies. Maintaining electronic equipment and systems in a state of serviceability is therefore a major challenge to railway infrastructure managers and must be supported by technical diagnosis. The need for diagnostics of infrastructure and systems being at the equipment of means of transport results from the process of their destruction, which is related to the time of equipment existence, the intensity of its use, the quality of maintenance or the level of operational quality. Information about changes in the technical condition of the equipment obtained as a result of diagnostics enables the effective restoration of the condition of their fitness obtained as a result of renewal. Therefore, scientific research is conducted and actions are taken to implement new diagnostic methods in the field of electronic, electrotechnical and IT systems.

In this Special Issue dedicated to the diagnostics of systems in cars, trains, planes and ships, we collect articles on many aspects of vehicle and infrastructure diagnostics, such as multi-sensor fusion, big data processing, sensors related to science/research, algorithms/technical development, analytical tools, synergy with sensors in electronic systems, data fusion and artificial intelligence methods for transport asset diagnostics.

Topics of interest include, but are not limited to:

Diagnostics of car electronic systems

Diagnostics of electronic systems of trains

Diagnostics on aircraft electronic systems

Diagnostics on electronic systems of ships

Diagnostics of electronic systems of infrastructure

Sensor data processing, data reduction, feature extraction and image understanding

Automatic target and obstacle detection and classification

Algorithms and methods for target tracking and collision avoidance

Artificial intelligence for navigation and sensor data processing

Big data processing for in-vehicle electronic systems

Path planning methods for autonomous vehicle navigation

The printed circuit board (PCB) is the core control unit of electromechanical equipment. In order to determine the influence of the coupling vibration caused by vehicle–road interaction on the PCB reliability of roadside electromechanical equipment, first, the dynamic load of the vehicle tire is solved by establishing the dynamic model of a vehicle road. Then, the acceleration response data generated by road vibration are obtained by solving the road finite element model. Finally, the power density spectrum of the acceleration response is taken as input excitation, and the deformation response of the PCB under vehicle–road coupling vibration is analyzed. The experimental results show that when the vehicle is driving close to the roadside, the vibration caused by vehicle–road coupling will lead to a large deformation of the PCB, and the deformation value reaches 0.170 mm, which can cause structural damage to the PCB. This shows that the vehicle–road coupling vibration can affect the reliability of the roadside electromechanical equipment; thus, the optimal design of the PCB layout is created. After optimization, the first-order modal frequency of the PCB is increase by 5.4%, which reduces the risk of the components breaking away from the PCB substrate. Full article

Rail interlocking systems follow the progress of technology and train speeds. Nowadays, new systems are designed based on microcontrollers and reliable software, requiring many hours of testing to ensure their proper functionality and bug-free coding. However, in many countries, there are still older relay solutions implemented that are not envisaged to be upgraded in the near future partially due to costs but mainly due to the fact they function very well, being based on a highly reliable element: the relay. However, specialized maintenance personnel are becoming more difficult to find, so automation systems that check the proper relay functionality are a key element to ensure a longer lifetime of existing systems. In this article, the authors present a monitoring solution based on magnetic sensors that proved capable of provide reliable information about the relays, hence revealing the first step in a relay automated control system.

Among a variety of problems with communication lines, the faults of surge protection modules in railway applications have a significant impact on the transmission line availability, especially if the devices are located in lightning-prone areas or other high-energy exposure areas, such as voltages or current changes. An advanced optimization of the surge protection module is proposed together with its verification, based on simulated waveforms for components and their limitations (e.g., power, peak power, maximum voltages, maximum currents, etc.). It allows for gathering information about the safety margin for each parameter of the components. This can be used to manage the probability of damage to the protection module. The authors have shown the power distribution during exposure that should be considered while developing new devices for railway transportation industry. Full article

The article compares the results of experimental and modelling research of switched reluctance motor at two different operational states: one proper and one with mechanical fault, i.e., with dynamic eccentricity of the rotor. The experiments were carried out on a test bench and then the results were compared with mathematical modelling of quasi-static and dynamic analysis of 2D geometry model. Finally, it was examined how the operation with dynamic eccentricity fault of the motor affected its main physical parameter—the phase current. The analysis was presented in the frequency domain using the Fast Fourier Transform (FFT); however, individual current waveforms in the time domain are also shown for comparison. Applying results of the research could increase reliability of the maintenance of SRM and enhance its application in vehicles for special purposes as well as its military and industrial applications.
