Abstract

In this paper, the indoor positioning based on acoustic wave is designed. A wearable sensor physiological data analysis detector based on the combination of infrared and ultrasonic is designed; the angle control circuit of the terminal camera is designed; the acoustic node is designed; the self-organizing wireless network communication protocol based on ZigBee is designed. The corresponding power supply circuit is designed. The acoustic node is distributed and controlled by multi-point, the infrared ultrasonic detection module is used to analyze and locate the physiological data of wearable sensor, and the main control terminal is used to analyze and process the data. A high precision surveillance system with large range and high precision is realized by using step motor control camera rotation angle control.

The intelligent driver of indoor acoustic positioning and monitoring system and the monitoring node based on acoustic wave are designed, and the indoor intelligent wearable sensor physiological data analysis, positioning and monitoring system is realized.The scheme of indoor acoustic positioning and monitoring system based on ZigBee acoustic wave and infrared ultrasonic positioning is feasible.
