论文摘要
现在，越来越多的家用电器已连接到Internet，从而实现了各种智能家居应用程序。但是，可能会阻碍智能家居进一步发展的一个关键问题被忽略了：小型电器是大多数家用电器的占用，但是它们很少受到关注，其中大多数人与互联网被切断。为了填补这一空白，我们提出了摩托车，这是一种声音通信方法，将小型设备与智能扬声器联系起来。我们的关键思想是利用直接电流（DC）电动机（是小型设备的常见组成部分）来传输声音消息。我们设计了一种名为“变量脉冲宽度调制”（V-PWM）的新型方案，以驱动直流电动机。摩托车实现以下3C目标：（1）舒适地听到，（2）与多个电动机模式兼容，以及（3）并发传输。我们使用商业设备实施摩托车，并在三个小型电器和十个直流电动机上评估其性能。结果表明，通信范围可以高达10 m
More and more home appliances are now connected to the Internet, thus enabling various smart home applications. However, a critical problem that may impede the further development of smart home is overlooked: Small appliances account for the majority of home appliances, but they receive little attention and most of them are cut off from the Internet. To fill this gap, we propose MotorBeat, an acoustic communication approach that connects small appliances to a smart speaker. Our key idea is to exploit direct current (DC) motors, which are common components of small appliances, to transmit acoustic messages. We design a novel scheme named Variable Pulse Width Modulation (V-PWM) to drive DC motors. MotorBeat achieves the following 3C goals: (1) Comfortable to hear, (2) Compatible with multiple motor modes, and (3) Concurrent transmission. We implement MotorBeat with commercial devices and evaluate its performance on three small appliances and ten DC motors. The results show that the communication range can be up to 10 m
