基于Modbus协议的腐蚀在线监测仪的通信设计

Design of Communication of Corrosion On-line Monitor Based on Modbus Protocol

  • 摘要: 介绍了利用Modbus协议实现腐蚀在线监测仪与组态王、WinCC等上位机组态软件的通信以及利用公共电话网(PSTN)进行腐蚀在线监测仪远程数据传输的方法。该通信方法已成功运用于工业循环水腐蚀参数的监测,数据传输可靠性高、实时性强,有一定推广应用价值。

     

    Abstract: The paper introduced methods of using Modbus protocol to implement communication between corrosion on-line monitor and configuration softwares such as King View and WinCC,and using PSTN to transmit remote data of the corrosion on-line monitor.The communication method has applied in monitoring of corrosion parameters of industrial circulating water,which has high reliability of data transmission,strong real-time,and certain popularization and application value.
