其中,传感器采集信号后,通过ADC模块转化为数字信号,输入MCU控制器进行数据处理,通过MCU控制器发送三路灯驱动信号驱动RGB氛围灯。其中,该氛围灯可以安装于车内多个位置。Among them, after the sensor collects the signal, it is converted into a digital signal through the ADC module, input to the MCU controller for data processing, and the MCU controller sends three-way light driving signals to drive the RGB ambient light. Wherein, the ambient light can be installed in multiple positions in the car.
示例性的,MCU上电后进行硬件初始化,硬件配置成功开始创建起始任务,在起始任务中成功创建五个主要任务后结束,同时五个主要任务开始循环执行:手势识别扫描与解析,温湿度检测与显示,语音识别检测与解析,空气质量检测与有害气体检测并显示,RGB-LED混色控制。Exemplarily, after the MCU is powered on, the hardware is initialized, the hardware configuration is successful, and the initial task is created. After the five main tasks are successfully created in the initial task, the end is completed. At the same time, the five main tasks start to be executed cyclically: gesture recognition scanning and parsing, Temperature and humidity detection and display, voice recognition detection and analysis, air quality detection and harmful gas detection and display, RGB-LED color mixing control.
在RGB-LED混色控制任务中,主要循环判断当前的酒精传感器与PM2.5传感器检测值是否超出阈值,这个阈值是可以自己提前设定的,默认的阈值为35。如果超出则执行红灯闪烁报警;否则继续判断当前模式并执行颜色模式或者温度模式。In the RGB-LED color mixing control task, the main loop judges whether the current detection value of the alcohol sensor and the PM2.5 sensor exceeds the threshold. This threshold can be set in advance by yourself, and the default threshold is 35. If it exceeds, the red light flashes to alarm; otherwise, it continues to judge the current mode and executes the color mode or temperature mode.
通过手势操作可以直接进入颜色模式。在手势控制颜色模式下,手势识别模块可以识别上滑、下滑、左滑、右滑四种手势,其中上滑手势对应氛围灯亮度调高指令,下滑手势对应氛围灯亮度调低指令,设计为1%至100%切换。左滑和右滑手势对应颜色切换,设计为20种颜色切换。You can directly enter the color mode by gesture operation. In the gesture control color mode, the gesture recognition module can recognize four gestures: slide up, slide down, slide left, and slide right. The slide up gesture corresponds to the command to increase the brightness of the ambient light, and the slide gesture corresponds to the command to decrease the brightness of the ambient light. 1% to 100% toggle. The left swipe and right swipe gestures correspond to color switching, which is designed to be 20 color switching.
通过语音唤醒词“氛围灯同学”可以直接进入语音控制颜色模式,本语音系统可识别“亮度调高”、“亮度调低”、“上一个颜色”、“下一个颜色”、“开灯”、“关灯”六种命令,并执行。Through the voice wake-up word "Ambient Light Classmate", you can directly enter the voice control color mode. The voice system can recognize "brightness up", "brightness down", "previous color", "next color", "turn on the light" , "Turn off the lights" six commands and execute them.
在温度模式下,判断从温度模块读取到的当前温度值,并通过换算得到对应的颜色值点亮。25℃时为白色,温度越高颜色越红,温度越低颜色越蓝,温度测量范围为0℃-40℃,其中0℃对应的RGB颜色为(255,1,1),25℃对应的RGB颜色为(255,255,255),40℃对应的颜色RGB信息为(1,1,255)。其余的呈线性分布。In the temperature mode, the current temperature value read from the temperature module is judged, and the corresponding color value is obtained by conversion to light up. It is white at 25°C. The higher the temperature, the redder the color. The lower the temperature, the bluer the color. The temperature measurement range is 0°C-40°C. The RGB color corresponding to 0°C is (255, 1, 1), and the corresponding The RGB color is (255, 255, 255), and the color RGB information corresponding to 40°C is (1, 1, 255). The rest are distributed linearly.
