    • A control system for a super-lifting device of a crane comprises a pressure-detecting element (21) for detecting the pressure of a variable amplitude oil cylinder and obtaining a measured pressure value, and a control element (22) for comparing the measured pressure value with the predetermined pressure value. When the measured pressure value is larger than or equal to the predetermined pressure value, the tensioning oil cylinder (23) is shortened, therefore increasing the tensioning pressure of the tensioning oil cylinder (23), reinforcing the tension of the super-lifting cable wire in the super-lifting device, and increasing the super-lifting moment applied to the main arm by the super-lifting device, which can effectively balance the pressure of the variable amplitude oil cylinder. A control method and a super-lifting device with the above control system are disclosed.

    • A method and a device of service migration in an automatically switched optical network are disclosed in the present invention, and the method includes: when receiving a migration indication message, a migration node sending an cross information checking request to a transmission plane (S101); when receiving a cross information checking success message, the migration node performing a slot resource migration (S102); and the migration node determining whether it is the destination node of the present service migration, if it is determined to be yes, an cross connection migration is performed directly, otherwise, the cross connection migration is performed after the indication signaling, which is sent by a downstream node and carries a cross connection migration scene, is received (S103). The present invention improves the reliability of the migration from PC to SPC, and further ensures the reliability of the migration by a strict state control and state refresh mechanism.
    • 本发明公开了一种自动交换光网络中业务迁移的方法和装置,该方法包括:接收迁移指示消息时,向发送平面发送交叉信息检查请求的移动节点(S101); 当接收到交叉信息检查成功消息时,迁移节点执行时隙资源迁移(S102); 并且迁移节点确定当前服务迁移的目的地节点是否被确定为是,直接执行交叉连接迁移,否则,在指示信令之后执行交叉连接迁移,该指示信令由 接收下游节点并携带交叉连接迁移场景(S103)。 本发明提高了从PC到SPC的迁移的可靠性,并通过严格的状态控制和状态刷新机制进一步保证了迁移的可靠性。
