Abstract:
Disclosed are an attraction device (100) and a connector, the attraction device comprising a control electromagnetic core (1) and an attraction component (2), wherein a cavity (3) is provided between the control electromagnetic core and the attraction component, and the attraction component slides up and down in the cavity by means of variation in the magnetic property of the control electromagnetic core.
Abstract:
The present disclosure provides a data acquisition method in network resource estimation, including: when querying data, a network resource estimation system reads a configured rule file, sets a query command according to a query rule of to-be-queried data set in the rule file, and transmits the query command to a network manager; and the network manager queries the data through an interface of the network manager itself corresponding to the query command according to the received query command, and returns a query result to the network resource estimation system. The present disclosure also provides a data acquisition system in network resource estimation. The method and the system can efficiently acquire the data required in network resource estimation, reduce the influence on network operation and management in the process of acquiring the data, and reduce the difficulty in developing the network resource estimation system.
