中文摘要: |
在太阳能一地源热泵耦合系统中,为了实现RS485设备与上位机间的通信,并在WinCC中实时读取超声波能量
表的各参数,利用USB-485转换器实现PC机与能量表间的数据传输,并利用OPC服务器Kepware使数据通过WinCC中
的OPC通道在上位机中实时显示。文中详细介绍了能量表与上位机间的通信原理、通信过程及调试结果,结果显示系
统所需要的参数均能在上位机中实时读取。经过实际测试,设计稳定可靠,能够实现超声波能量表与上位机间的通信。 |

ln the coupling system of solar energy-ground source heat pump,in order to achieve the communication
between RS485 equipment and upper computer.read the parameters of sharky in real-time in WinCC, exploitd the USB-
485 converter to realize data transmission between the PC and sharky,and data were displayed in the upper computer in
real-time through the OPC channel in Win-CC by OPC server Kepware. This paper introduced the communication
principle, process and the result of debugging between sharky and upper computer in detail. The result shows that all
needed parameters can be readed in the upper computer. Through the actual test. the design stable and reliable. can
realize the communication between sharky and upper computer. |
