新能源汽车低电量运行下的无线测距及智能语音交互系统

自从2008年新能源汽车进入中国市场以来,新能源汽车低电量运行下的续航里程短,无法及时找到充电桩等问题层出不穷,导致汽车追尾、抛锚至路边等情况时有发生,轻则浪费车主时间,带来不好的行车体验,重则危及人身、财产安全。本设计采用语音识别模块对用户发出的关键词指令进行识别,辅以语音播报模块给出相应问题的完善解决方案,若识别到开机指令,系统开始语音播报并提醒车主做好预防措施;若识别到测距指令,则通过LORA模块的飞行时间测距法测量新能源汽车到无线网络节点间的距离,并在显示屏上显示;若识别到汽车电量不足的指令,语音播报模块则会给出相应的汽车低电量运行下的意外状况处理方案。该项目产品可以投入中国新能源汽车的市场,其完善的意外状况预防及处理体系为新能源汽车用户提供了更加优质的服务。

Since the new energy vehicles entered the Chinese market in 2008,new energy vehicles have a short driving range under low power consumption,and can not find the charging pile in time.As a result,the vehicles rear end and anchor to the side of the road from time to time,which may waste the owner's time,bring bad driving experience,and even endanger personal and property safety.In this design,the voice recognition module is used to identify the keyword commands issued by users,and the voice broadcast module is used to provide a perfect solution to the corresponding problems.If the start-up command is recognized,the system will start voice broadcast and remind the car owners to take preventive measures;if the ranging command is recognized,the distance between the new energy vehicle and the wireless network node is measured by the time-of-flight ranging method of LORA module,and displayed on the display screen;if the command of insufficient vehicle power is recognized,the voice broadcast module will give the corresponding accident handling scheme under the low power operation of the vehicle.The products of the project can be put into the market of new energy vehicles in China,and its perfect accident prevention and treatment system can provide better service for the users of new energy vehicles.
