摘要:
提出了一种利用信号平均值的动态特性来判断噪声和信号的方法,该方法可较准确地判断出前后一段时间信号特性的一致性和突发信号的特性.利用这种方法设计了能够自适应环境噪声的声光控制LED照明灯,实验表明,该灯具有高触发灵敏度、低功耗、工作稳定、成本低、电路简单等优点,可适用于工作在环境噪声较大的场合,如装有排风扇的卫生间、走廊等场所.
Abstract:
Put forward a judgment method of noise and signal which based on the dynamic characteristics of signal average. This method can accurately judge the characteristics of the burst signal and the consensus of the characteristics of the signal in two consecutive periods of time. A sound-and-light controlled LED lamp which based on adaptive ambient noise is designed by this method. Experiments show that the LED lamp has the advantages of high trigger sensitivity, high operation stability, low cost, simple circuit structure and micro-power consumption, which can be widely used in the environment of high ambient noise such as corridors, public toilets and so on.
