Hydropower plant communication manager based on IEC60870- 5-104 protocol

A design of hydropower plant communication manager based on WinCE and IEC60870 - 5 - 104 protocol is introduced. The WinCE based serial programming technique,Ethernet programming technique and multi-thread programming technique are used to realize the communication between the communication manager,MOXA UC7410CE embedded industrial computer,with different devices via various protocols,such as DL / T645,CDT,Modbus,etc.. IEC60870 - 5 - 104 protocol is used to communicate with the monitoring computer. The frame structure of IEC60870 - 5 - 104 and its implementation in WinCE system are analyzed,and the flowcharts of sending and receiving procedures are presented. A method to manage multiple TCP client connections is also presented,enabling several host computers connecting to the communication manager and sharing data. The high reliability of the embedded industrial computer guarantees a long-term stable operation.
