摘要
设计了一种基于ZigBee技术的气介式超声波水位节点装置。节点以CC2430为核心,实现了带有温度补偿的自发自收超声测距系统及削浪滤波算法。该系统具有组网灵活、精度高、成本低、功耗低、可靠性高等特点,可以解决大尺度河工模型试验中现有仪器在断面多、参数多、试验运行时间长、测点同步性和实时性要求高等条件下的量测难问题。
An air-coupled ultrasonic water gauge node based on ZigBee technology was designed.The self-transmitting-self-receiving ultrasonic ranging system with temperature compensation and wave-elimination filtering algorithm was realized by taking CC2430 as the core.The system was characterized by flexible networking,high precision,low cost,low power consumption and high reliability.It could be employed to solve problems in large-scale river model experiments such as multiple sections,multiple parameters,long running time,high requirements for synchronous and real-time measuring,which are difficult for the existing instruments.
