Detection device and method used for full-width discrimination of negotiable securities

The invention provides a detection device and method used for full-width discrimination of negotiable securities. In the detection device, two detection stations are arranged on a delivery channel, each detection station is provided with a set of hold-down belts, in the two detection stations, the positions where the negotiable securities are held down by the hold-down belts are different, and thus the positions where acquisition signals of the negotiable securities are shielded by the hold-down belts of the two stations are different; by comprehensively analyzing the transmission characteristics acquired by the two detection stations respectively, the full-width non-blind-area detection results of the negotiable securities are obtained. Through the dual-station detection method, the negotiable securities are held down on at least one side on the detection stations, the paper delivery stability is guaranteed, meanwhile, full-width non-blind-area detection of the negotiable securities is ...

Offshore wind plant sea wave monitoring method and monitoring equipment thereof

The invention provides a sea wave monitoring method for an offshore wind plant, which comprises the following steps of: 1, acquiring the impact force of sea level sea waves on a unit tower through a first monitoring mechanism to obtain first sea wave impact force data; step 2, collecting the impact force between the splashed sea waves and the seawater undercurrent through a second monitoring mechanism to obtain second sea wave impact force data; and 3, receiving the first sea wave impact force data and the second sea wave impact force data through the controller, and comparing the first sea wave impact force data and the second sea wave impact force data with set values through the controller.
