基于QXN的车机蓝牙无线监控系统

摘 要: 车载终端与便携设备的互连技术推动了整个车控系统的飞速发展。随着Telematics技术的不断应用和创新，单靠车辆内部监测和控制系统已很难满足现代用户的苛刻要求。为此，提出基于QNX的车机蓝牙无线监控系统方案，以手机端和车载端的蓝牙SPP协议为基础，设计CAN-USB模块作为车机通讯枢纽，对两端蓝牙无线指令数据进行对等收发和处理；采用CAN总线实时采集和配置车辆ECU的各项性能参数。实验表明：该方案不仅能用手机对车辆运行状态进行实时监测和控制，而且有效提升车辆操控的互联性和智能性。

Vehicle and Phone Wireless Monitoring System of Bluetooth Technology Based on QNX

The entire vehicle control system develops rapidly by the promoting of the vehicle terminal and portable devices. With the continuous application and innovation of telematics technology , vehicle interior monitoring and control system becomes very difficult to meet the demanding requirements of modern users. This paper presents vehicle and phone wireless monitoring system of bluetooth technology. With the mobile terminal and car-side Bluetooth SPP protocol, CAN-USB module was designed as a communications hub for both terminals, which is used to peer transceivers. Otherwise, using CAN line acquisition and configuration of the vehicle ECU performance parameters. Experiments show that: The program can not only monitor and control the running state of the vehicle by the phone, but also can effectively enhance the vehicle interconnectivity and intelligent.
