针对DTU与DSC之间通信数据稳定性差、大时空数据存储时数据库负荷重、维护困难以及DSC和客户端管理软件开发困难等缺点,分析了DTU、DSC之间通信的特点,采用了注册包和心跳包合二为一的方法。利用该方法对通信协议设计了1个闭环,2个开环的工作模式。实践证明,这种设计提高了通信的可靠性,降低了DSC和客户端管理软件的开发难度,减轻了DSC的负荷,节省了流量,达到了设计要求。 |

Abstract: |
The backward technology in DTU protocol exists the problems of poor stability, low data security, heavy loader of database and difficulty to maintain and develop the software of DSC and clients. This paper analyzes the characteristics of communication between DTU and DSC, adopts the method of the registration packet and heartbeat bag together, and designs a closed-loop two-ring-opening operation mode among the communication protocol. The result shows that this design improved the reliability of the communication, reduces the development difficulty of DSC and client management software, and reaches the design requirements. |
