Design And Implementation Of Vehicle Bluetooth Voice Control System

With the increasing number of modern cars, performance continues to improve, in order to improve driving safety, entertainment and comfort, there are many new problems about the operation of the equipment on the vehicle. At high speeds, the use of eyes and hands to operate the vehicle equipment (such as: vehicle navigation, vehicle DVD players and radios, etc.), will distract the attention of the driver, and will affect the safety of driving, will reduce the portability and maneuverability of the vehicles as well. Therefore, the current marketplaces need to develop new control system to solve the evils of the traditional vehicle operation: the use of voice-wireless-controlled solution came into being. Abroad famous automobile manufacturers have introduced the concept vehicle with voice control, and in part of the B-class cars with a specific voice control devices (such as: turn on the radio and the election for CD discs, etc.). This is also the future development trend. With the rapid development of the automobile, the function components gradually increased. Thus require the new approaches and methods to control them. The technology of voice-wireless-control can liberate the hands, eyes, and the drivers can focus more attention on the road, and they also can control entertainment, auxiliary and power system.Based on the background of the selected topic and the needs of the market requirements, this paper proposed the design of the Vehicle Bluetooth Voice Control System. The works have been made around the design and research of the Vehicle Bluetooth Voice Control System. From a practical point of view, the author studied the current status of the market and the technology backgrounds, learning the relevant knowledge of the Bluetooth system and the voice control system; investigating the specific needs of the market for Bluetooth Voice Control System; designing the hardware platform of the Bluetooth Voice Control System; achieving the software function based on the hardware platform of the Bluetooth Voice Control System. Thus, the article completed the following work:First, according to the market demand, the author have conducted a detail investigation and research to the existing technology of Bluetooth Voice Control System, and made a careful reading and learning to the architecture of Bluetooth system and the relevant knowledge of the voice control system. The paper made a careful analyzed to the needs of the market user and the future development trends.Second, according to the above learning activities, the author have made a careful studied and compared to some of the popular project on the market at the moment of the Bluetooth Voice Control System. Then according to the needs and the target, a careful hardware anglicizing and designing to the Bluetooth Voice Control System have been made. There is a detailed presentation to the overall hardware circuit and the every part of the circuit. Completed the hardware design of all units, and according to the some basic principles of PCB manufacture designed entire system's PCB.Third, it made a detailed discussion to software design of the system according to the function of the system. At this moment, I have made a systemic software requirements analysis to the Bluetooth Voice Control System, and the thesis have made a detailed use cases to the system as the method of the software engineering. A flow chart and the implementation of function to every part of the system have been given according to the detailed analysis.Fourth, in the above design completed, a serious experiment and debug to the Bluetooth Voice Control System have been made. Summarizing some typical problems in the system design and system debug, and put forward solutions. In this section, first, the thesis have made adequate preparations before the system debug, checked the PCB of the system hardware platform. Then, it made a systematic debug to the every parts of the system, and meticulously recorded to the debugging process and issues of the every part of the system, and giving a serious treatment.Fifth, a careful summary to the design of the Vehicle Bluetooth Voice Control System have been proposed until the above issues to be resolved. Summing up the author's all the work of the design of the Vehicle Bluetooth Voice Control System, and looking into the distance the future trends of the system.The experiments show that the system to meet the market demand, but also to achieve the goals of the design expectations. Compare with the existing products, this system has increased in all aspects.
