Automatic glutinous rice airing device

Номер: CN116222167A
Автор: SU ZHENCAN, LI ZHUCHUN
Принадлежит:

The invention relates to the technical field of automatic airing, and discloses an automatic glutinous rice airing device which is characterized in that rotating rollers are rotationally connected to the two ends of the interior of a first shell through bearings, and a second shell is fixedly mounted on one side of the first shell; one end of the rotating roller located in the first shell on the left side penetrates into the second shell and is fixedly connected with a first bevel gear in a sleeving mode, and a second bevel gear is meshed with the surface of the first bevel gear. When the automatic glutinous rice airing device is used, the airing rod on the topmost portion is moved to the bottom of the first shell through forward rotation of the rotating motor and cooperation of a through groove; the glutinous rice bundled in advance is inserted into the insertion rods, after the topmost airing rod is fixed and filled with the glutinous rice, the rotating motor is operated to rotate reversely ...

The invention relates to the technical field of code recognition, in particular to a novel coupled oscillator model for code recognition and a code recognition method. The method comprises the steps of obtaining a standard mode group and a defect mode; grouping the plurality of standard modes; for each group, a coupled oscillator model corresponding to the group is established, and the model comprises an uncoupled item; identifying a defect mode by using the coupled oscillator model by selecting an appropriate value of the strength of the uncoupled item so as to output a standard mode closest to the defect mode in the group; and summarizing the standard modes output in all groups, taking the standard modes as a new standard mode group, and finally obtaining a standard mode closest to the defect mode by repeating grouping and identification processes. According to the scheme, the calculation amount in the recognition process can be reduced, and the code recognition speed is increased.

The invention discloses a critical clearing time method for power system disturbance based on a frequency synchronization theory of a second-order inhomogeneous Kuramoto model, relates to a critical clearing time method for a power system after disturbance, and aims at solving the problems that an existing method cannot well correspond to a power system model, and an attraction domain degree of a system balance point is not researched in the existing method and cannot be applied to transient stability analysis. The method comprises the following steps: 1 building a second-order inhomogeneous Kuramoto model corresponding to the power system model; 2 modifying parameters of the second-order inhomogeneous Kuramoto model; 3 solving a state variable of the system at the disturbance clearance moment, and solving parameters C (delta0, omega0 and alpha) in a criterion according to the state variable; 4 judging whether the system can be kept in synchronism stability after certain disturbance according ...
