摘要
介绍了一种基于TMS320F2812 DSP信号处理器的汽车安全提示装置的设计与实现,该装置能通过TMS320F2812 DSP信号处理器实时接收所驾驶汽车的车速,当车速达到20km/h时,它会控制执行机构反锁车门,防止车速过高导致意外发生,另外当驾驶员或是乘客在下车开启车门时,该装置还能控制语音芯片进行安全报警提示,防止由于没有按照正确下车的方法下车而发生交通事故。该装置工作相对稳定可靠,能快速准确进行安全提示,使驾驶员,特别是新手能安全驾驶车辆,减少交通事故的发生。
This paper introduced a design and implementation of vehicle security warning tone device based on TMS320F2812 DSP high speed digital image processing chip,this device can receive oneself car＇s the real time speed according to the TMS320F2812 DSP, When the speed reaches 20kin/h, it will control actuator locked door, prevent excessive speed lead to accidents, and when the driver or passengers in the car open the door, the device can also control a voice chip security alarm, prevent traffic accident because of no according to the correct method of taking offthe car .This device Works very stable and reliable,and can quick and exact to work, let driver, especial the new driver can driving on safe,decline the traffic accident.
