摘要
研究了一种基于ZigBee通信的水表无线校验装置。其采用星形网络拓扑结构,终端节点使用点播通信方式定时把数据传输给协调器。终端节点采用对数比例等分时间间隔的数据发送算法,在数据采集后根据对数比例等分时间定时发送数据,有效、快速地避免无线通信的同质干扰和数据拥堵。
A water meter wireless calibration device based on ZigBee communication is reported,which adopts star networks topology and its terminal node uses the point-to-point communication method to periodically transmit data to the coordinator. The terminal node adopts data transmission algorithm with equal time interval by logarithmic scale,it periodically transmits initial data after data acquisition according to the logarithmic scale equal-time. This method can effectively and quickly avoid homogenous interference and data congestion of wireless communication.
