摘要
在蓄电池充电时,需要实时监控蓄电池的电压、电流等参数。为解决这一问题,设计了一种Zigbee无线传输网络,各个节点将数据传送到主节点,然后主节点通过串口传给上位机。上位机通过WinCC组态软件编程读取串口接收的数据,并在界面通过表格和曲线的形式显示。使用情况表明,其工作可靠,操作方便,有较强的可扩展性。
The voltage and current should be monitored during the process of storage battery charging.So a Zigbee wireless network is designed to solve this problem.The subnode send the data to the mainnode,and then send it to the PC through serial bus. Then,WinCC is used to read the data from the serial bus￡-and display it in the form of curves and forms.
