| dc.description | Automotive industry has undergone a tremendous transformation from mechanical system to electronic operation and control systems. Planes, trains, buses and automobiles which are facilitated by infotainment, intelligent cruise system, internet, vehicle to vehicle networking, advanced security and safety systems, intelligent self-diagnostic and control systems require high bandwidth in the same infrastructure. Consequently, various types of cable are installed in the vehicle to accommodate data transmission and multiplexed system invented to overcome bandwidth shortage. Gradually, the versatility of data to be transmitted with different protocols and standards, complexity of network design to reach maximum bandwidth and the additional types of cable has become the most critical issue. Glass Optical Fibers (GOS) has been introduced to the automotive industry but due to the high cost of implementation, complication at installation and maintenance, the designers continue to look for a better solution. The new solution needs to overcome GOF limitations and presents some superiority. Plastic Optical Fibers (POF) came to the centre of in-vehicle networking designers’ attentions due to its cheaper price, easy to implement, better flexibility and safer to handle. Wavelength Division Multiplexing over POF which considerably increases the bandwidth has become a topic of interest in this field. Because of its increasing popularity, WDM over POF is the main highlight in this research. The objectives of study are: to justify POF as a suitable solution for instrumental data transmission in the vehicle networking, to fabricate transmitter and receiver modules for applying current in-vehicle networking and to design a practical WDM over POF model for integrating transmission of three different wavelengths simultaneously on single fiber. The main is purpose reducing wire harness, implementation cost, space occupation and increasing backbone speed. This study investigate the application of WDM over POF in transferring video, audio and instrumental (here engine) data. In order to meet the research aims, a laboratory system of digital multiplexer, de-multiplexer and optical transmission system Developed. The Laboratory model is based on the real engine signals, Labview programming, and using Multifunctional data acquisition card. The RS-232 was used as a digital communication link between engine sensors module and optical convertor. After that, transmitter and receiver modules were fabricated using microcontrollers and placed in a real car engine network for experimental work. These prototypes was then used to replace the laboratory system and tested for the same functionality. Finally, a network was developed using the fabricated devices to transmit one dedicated wavelength out of the three predefined wavelengths. Different aspect of the presented WDM model was examined and investigated. The designed model can carry at least eight sensor signals on 660nm wavelength, audio signal on 470nm wavelength, and video signal on 520nm wavelength. Transmission speed on RS-232 set to the 115200 baud rate. The WDM was arranged in bidirectional model to achieve better results. The whole model is considerably inexpensive than the preceding solutions. Since the optical attenuation in MUX and DMUX parts are high and the interferences between the three wavelengths affect the precise filtering of a certain wavelengths, the presented system can send audio and video signals up to 3 meters with the received power in between -32.7 to -39 dBm, and up to 9 meters with -38.2 dBm (without repeater).,Master / Sarjana | |
