资料介绍

针对车辆间传统灯语交流方式沟通不便、不安全的现状,设计了一种基于可见光通信(VLC)技术的车辆安全预警系统。该系统以DSP处理器为核心,利用可见光进行通信,以LED作为信号的发射源,用强度不同表征信号,并将其加载到LED发光器件上,通过LED灯的明暗闪烁来传递所需要的信息;App音频输入后经DSP处理器处理将音频信号转换为电信号,并将其加载到LED灯上实现信号发送;指定方向的车辆在收到光信号后,经过处理器处理后最终以音频信号的形式表达,发送方车辆所要传达的信息。试验证明,该装置操作简单方便,信息传送快速、高效,能达到预期的安全预警目的,在现有汽车和未来无人驾驶汽车的安全领域有较高的市场推广价值。

Aiming at the inconvenience of traditional lamp language communication between vehicles,a vehicle safety early warning system based on visible light communication(VLC) technology is designed. The system takes the DSP processor as the core,uses visible light to communicate,uses LED as the signal source,uses different intensity to characterize the signal,and loads it onto the LED light-emitting device,and transmits the required information through the light and dark flashing of the LED light. After the App audio is input,the DSP processor processes the audio signal into an electrical signal and loads it onto the LED lamp to realize the signal transmission. After receiving the optical signal,the vehicle in the specified direction is processed by the processor and finally in the form of an audio signal. Express the information to be conveyed by the sender's vehicle. The test proves that the device is simple and convenient to operate,the information transmission is fast and efficient,and can achieve the expected safety warning purpose. It has high market value in the safety field of existing cars and future driverless cars.
