  • Publication number: 20230014095
    Abstract: A method and system for recognizing environmental protection equipment based on a deep hierarchical fuzzy algorithm. The method includes the following steps: (1) acquiring harmonic signal data of the environmental protection equipment by harmonic detectors, and acquiring type information of corresponding environmental protection equipment on site for constructing a training sample database; (2) extracting a feature vector of the data in the training sample database by a local mean decomposition method, and training, by using the training sample database, a deep hierarchical fuzzy system constructed on the basis of a least square method, so as to construct a recognition model; and (3) evaluating the inputted harmonic signal data by using the recognition model to determine whether inspected equipment is the corresponding environmental protection equipment.

  • Patent number: 10974354
    Abstract: A blank assembly for a housing, a housing, a manufacturing method for a housing and a terminal are provided. The blank assembly includes: a first blank, a second blank and a filler. The first blank defines a slit along a thickness direction of the first blank, the second blank partially extends into the slit, an outer surface of the second blank located in the slit is spaced apart from an inner wall of the slit, and the filler is filled in the slit. In the blank assembly according to the present disclosure, the second blank partially extends into the slit and a filler is used to fill the slit to connect the second blank located in the slit with the first blank, the second blank may be partially arranged in the slit in an embedding manner.

  • Patent number: 10536480
    Abstract: The present disclosure provides a method and a device for simulating and detecting DDoS Attacks in software defined networking. The method comprises: adding zombie hosts in a preset linear increasing mode and an incremental mode, and launching stealthy DDoS Attacks on a data plane to a preset target switch in a software defined networking through all zombie hosts; synchronously updating a pre-built attack flow monitoring table on a controller of the networking according to updating of flow tables on all switches; periodically detecting the monitoring table to determine whether the monitoring table includes a monitoring table entry having existence duration over a preset duration threshold; and determining that a network flow corresponding to the monitoring table entry is a stealthy attack flow on the data plane of the networking when the monitoring table includes the monitoring table entry having the existence duration over the preset duration threshold.
