The invention relates to a data and control synchronization method and device of a cascade real-time system and a medium, a cascade real-time system cross-cluster synchronization target node is determined according to a consistency service coordinator, and the method comprises the steps that any station server cluster master node synchronizes real-time data to a central server cluster master node; and a process of synchronous control from the master node of the central server cluster to the master node of the target station server cluster, wherein the master node of the station server cluster synchronizes all data and change data to the master node of the central server cluster, the standby node and the standby node of the station server cluster. And the station server cluster main node receives and processes the control command issued by the central server cluster main node or the control command issued by the station work station, and feeds back a control back correction command to the corresponding work station after processing is completed. Compared with the prior art, the method has the advantages that the consistency of data synchronization and the effectiveness of control command execution can be ensured, and the like.
本发明涉及一种级联式实时系统的数据与控制同步方法、设备及介质,级联式实时系统跨集群同步目标节点根据一致性服务协调器确定,包括任意车站服务器集群主用节点往中心服务器集群主用节点同步实时数据,以及中心服务器集群主用节点往目标车站服务器集群主用节点同步控制的过程,车站服务器集群主用节点往中心服务器集群主用节点、备用节点和车站服务器集群备用节点同步全数据和变化数据;车站服务器集群主用节点接收中心服务器集群主用节点下发的控制命令或车站工作站下发的控制命令并进行处理,处理完成后将控制返校命令反馈到对应工作站。与现有技术相比,本发明具有能够确保数据同步的一致性和控制命令执行的有效性等优点。
