In recent years , some new challenging problems have come forth in automation systems with the fast development of electric power industry . firstly , to build transformer substation with no - operator , which often causes abnormal or even wrong data . secondly , alarming module should be well strengthened in no - operator dispatching 近年来,电力工业快速发展对自动化系统带来了一些新问题:特别是通过变电站无人值班建设,误发信息出现频繁,给正常运行监控带来很大麻烦;无人值守电网的调度,需要强大的告警功能;无人值守变电站新的管理模式,也对调度自动化scada系统功能提出了新的要求。
I put forward a new way that uses the combination of the " flow " method and the " sequence number " method , which aiming at solving the problem that one host is connected by several front transaction hosts and one front transaction host is connected by several member servers . the new way can ensure the unique receiving of data transmission , error checking and re - transmitting of the wrong data packages , especially focuses on the interpretation of the principal of " flow " method and its implementation way 针对一台交易主机挂接多台交易前置机、一台交易前置机挂接多台会员端服务器的体系结构以及双向实时数据传输的特点,提出了“流( flow )机制”和“序列号机制”相结合的思想来实现协议数据传输的唯一性处理、数据包丢失检测和错误重传;着重说明了“流机制”的基本工作原理和实现思路。
