摘要
针对常规RTU在无GPRS网络覆盖区域无法使用的问题,设计了RTU接口控制器,该接口控制器通过对RS 232接口扩展,使RTU能够获取和处理基于光通信技术、ZigBee无线通信技术和其他工业总线技术网络的数据,从而延伸了RTU的测控距离和扩展了RTU的测控范围。
A RTU interface controller is designed since the traditional RTU can＇t be used in some sections of no public GPRS network coverage.Based on the RS 232 interface expansion,RTU can process and acquire the data through optical communication technology,ZigBee wireless communication technology and other industrial bus technology,so as to extend the monitoring range and scope of RTU.
