Abstract


With modern living standards improve, the family car gradually increased, traffic accidents are increasing with increasing vehicle. Especially the driver using a mobile phone in the car due to the number of traffic accidents straight up. Many countries even decree prohibited the use of mobile phones during driving. But if the car handsfree installed, the driver can be used in the process of driving handsfree. Therefore, the domestic and foreign markets also cater to various user requirements speakerphone. Speakerphone in the process of driving the driver can not contact mobile phone to make and receive calls, and even voice control the phone, listen to mobile music. As part of the automotive electronics, car handsfree can be selected for the high-end models of the bus device or bus system independent car electronic devices. The system uses CAN bus technology designed with the bus speakerphone. Read from the bus-vehicle data set, read the relevant parameters and the use of hands-free device control connected to the handsfree phone. The system uses high-end cars Low-speed CAN bus, car hands-free system the true sense of the integration of the car. The application of CAN bus not only improve the technological content of products but also improve the stability of the products work. The car handsfree wireless connectivity solutions for Bluetooth wireless communication protocol. Bluetooth technology is a short-range wireless communications products solutions, widely used in the field of wireless data transmission, voice communication. Vehicle system with the user's mobile phone to be achieved within a narrow range in the car, car hands-free system with mobile phone wireless Internet, Bluetooth technology, globalization, openness and high-end mobile phone Bluetooth function of popularity as the preferred. The contents of this paper is a design based on CAN bus Bluetooth hands-free system, use the key value read on the steering wheel inside the car CAN bus, car hands-free system processing key operation, to control Bluetooth module and cell phone communications. The hands-free system using Bluetooth technology and Bluetooth mobile phone mating connector, and wireless control of their mobile phones. Firstly a brief introduction to the origin and development prospects of the automotive CAN bus technology, and then analyze the application of this topic related to the Bluetooth communication protocol system and hands-free application framework. Based on this set based on CAN bus Bluetooth hands-free system solution for the requirements of the subject, from both hardware and software aspects of the design of the system were described in detail. Program to Taiwan 9 Asahi the production BMA39 Bluetooth module for Bluetooth communication module and Bluetooth phone communications, and communication through the UART and PCM interfaces with the microprocessor and DSP connection. Body CAN bus system hardware use Microchio company dsPIC30F4011 microcontroller as the core microprocessor, the microcontroller comes with a CAN controller. CAN bus driver the TJA1041 chip as the interface between the CAN controller and the physical bus. Microprocessor dsPIC30F4011 with the vehicle CAN bus communication, processing CAN bus data to coordinate the operation of the entire system. Microcontroller serial teeth and monitoring module communication system uses state-of-the-art DSP technology as echo cancellation noise suppression unit, along with text-to-speech module, can achieve real-time information on voice prompts and read aloud text messaging capabilities. Finally, the prototype of the indicators of the system through real-time road test carried out to test and debug its performance to meet the design requirements, completed the the Bluetooth hands prototype system based on CAN bus.
