| 摘 要： | 随着SCADA系统负荷的不断增大，传统的通信模式已逐渐无法满足系统发展的需要。在SCADA系统中采用组播的通信方式，可以有效地提高数据传送效率，改善网络性能，但由于组播不保证数据报文的可靠传输，因此，根据应用环境特点，在组播中加入差错控制机制，有效提高了组播通信的可靠性，以适应SCADA系统通信需求。

| Abstract: | With load of SCADA system development, the traditional communication mode has not met the system developing demand. Using the group broadcasting mode in SCADA system, it can increase the data transmitting efficiency and improve network performance. But the group broadcasting can not guarantee trustiness transmission. Wherefore, based on application condition, the error control mechanism is joined into group broadcasting; it improves reliability of group broadcasting, and suits communication demand of SCADA system. |
