为实时获取智能电动车的状态信息,将液晶显示器及语音芯片应用于智能电动车系统。智能电动车由两个模块组成:电动车模块和无线控制模块。无线控制模块向电动车发送命令,电动车依据接收到的命令动作。无线控制模块在发送命令的同时,将命令信息实时显示在液晶显示器上,并通过语音芯片发出语音提示。语音提示部分同时具有现场重录功能。在概要介绍系统组成的基础上,着重分析了液晶显示及语音提示的设计,最后给出了无线控制模块实物图。实际系统运行结果表明,液晶显示和语音播放与无线发射命令同步,语音模块现场重录功能便于实现。

In order to get the information of the motor car in real time,the LCD and voice chip are used in the intelligent motor car system. The intelligent motor car system includes two modules,which are motor car and wireless control. The motor car operation is controlled by the instruction received from the wireless control system. When the instruction is sent out,the instruction would be displayed on the LCD and the voice chip would also send out responsive sound. The voice module could be recorded in the field. Based on the general introduction to the system,the LCD and voice module are analysed. The picture of wireless control module is given at last. The result of the actual system shows that LCD display and voice module are synchronous to the instruction sending,and the recording function of the voice module is convenient to realize.
