从Redis 里面取值

 if (KeyValueOperator.CreateInstance().Exist<RealTimeDataModel>(nJTerminal.SerialNum))
                {
                    RealTimeDataModel rtModel = KeyValueOperator.CreateInstance().Get<RealTimeDataModel>(nJTerminal.SerialNum);
                    model.OperationDepth = rtModel.OptRtDepth; //作业深度 
                }
                else
                {
                    model.OperationDepth = 0;
                }
