为了提高家庭监控系统的可靠性，本文设计并实现了一个基于嵌入式系统的多超声波传感器模块的家庭监控系统。每个超声波传感器模块包括发射器和接收器，并且模块沿线方向放置。由于超声波传输会以波束角传播，因此我们使用多个超声波接收器来接收超声波传输。如果任何入侵者通过超声波感应区，超声波的传播将被人体阻挡。由于接收器不会接收到超声波发射器的任何传输，因此系统将在有人通过监视区域时进行感应。我们使用多数表决机制（MVM）的一组传感器。如果传感器组中超过一半的传感器检测到信号阻塞，则多数表决程序启动网络摄像机。数学方程和传感实验表明，我们提高了系统的可靠性（1）。
In this paper we design and implement a home surveillance system based on an embedded system with multiple ultrasonic sensor modules to enhance the system's reliability. Each ultrasonic sensor module includes a transmitter and a receiver, and the modules are placed in a line direction. Because the ultrasonic transmission will spread at a beam angle, we use multiple ultrasonic receivers to receive the ultrasonic transmission. If any intruder passes through the ultrasonic sensing area, the ultrasonic transmission will be blocked by the human body. As the receivers will not receive any transmission from the ultrasonic transmitter, the system will sense when someone is passing through the surveillance area. We use a Majority Voting Mechanism (MVM) for a group of sensors. If over half the sensors in a sensor group sense a signal blocking, the majority voting program starts the Web camera. The mathematical equation and the sensing experiment show that we improve the system's reliabilities(1).
