语音播报GPS信息功能的电路系统

语音播报GPS信息功能的电路系统 随着全球定位系统GPS(IGlobal Position System)应用技术的日趋完善，GPS在各行业中的应用正在迅速发展和扩大。尤其是在汽车运营系统中，GPS的应用已经十分广泛。用于车载的GPS接 收系统可以全天候、高精度给出车辆位置的经纬度信息。结合电子地图，可以极大地方便驾驶员寻找正确道路。如果应用在出租车中，又可以实现运行监控，既便于 公司对车辆的统一调度，又在一定程度上保障了驾驶员的安全。 但是，目前市场上使用的大部分GPS导航系统都是通过液晶屏显示的方式给出导航信息。在一些场合(如车辆驾驶过程)中，路面情况复杂多变，驾驶员的注意力高度集中，单靠眼睛查看GPS信息有所不便。 本文设计的具有语音播报GPS信息功能的电路系统，采用单片机读取GPS接收模块的定位信息，在进行分析处理后自动转换为控制代码，通过语音组合形成定位信息的语音播报。由于驾驶员开车过程中可以直接听到有关导航信息，减轻了靠眼睛观察的负担，从而提高了行车的安全性。 1 系统电路设计 本系统主控芯片采用ATMEL公司的89C2051单片机(该芯片的最大特点是使用方便，价格低廉。GPS模块选用Position公司的GPS-05型GPS接收模块，语音播报则采用北京中青公司推出的PM50语音处理芯片。 1.1 GPS-05型GPS接受模块介绍 Position公司产的GPS-05型GPS模块有体积小(25×25mm2)、精度高、易安装、控制简单(串口控制)、功能强大等特点，可以给出经度、纬度、高度、速度、运动方向等多种信息，具体参数如1所示。 advantages, facing the Yangtze River Delta, Pearl River Delta, Shandong peninsula, Beijing-Tianjin-Tangshan area, targeted investment promotion several times.
