Method for improving control accuracy of hot rolling width

The invention discloses a method for improving the control accuracy of hot rolling width, which is a width control method for combined rolling of hot rolling rough rolling vertical roll-horizontal roll in a rough rolling area in a hot rolling device. The method comprises the following steps: establishing the control model relation among the width control quantity, accumulated rolling length and the width of a rolling material by introducing the roll surface roughness into rough rolling width control, then determining the thickness reduction of each pass of each roll housing according to the total thickness reduction of a rolled piece, and then predicting the spread of each pass according to the control model and determining the width of a target outlet of each pass according to a width reduction distribution principle so as to determine the roll gap of a vertical roll of each pass; and realizing the width control on the outlet of each pass by controlling the roll gap of the vertical roll, and finally realizing the control on the target width of the rolled piece in the rough rolling area in the hot rolling device. The method solves the problem of width fluctuation when a rough rolling horizontal working roll is replaced every time in the prior art, reduces the intervention of operators, and can reduce the failure rate of rolling width and production cost.

Spectrum reconstruction method and system based on multichannel imaging system

The invention discloses a spectrum reconstruction method and system based on a multichannel imaging system, which are used for performing spectrum reconstruction according to the camera response values of a training sample to-be-selected set and a to-be-reconstructed sample set acquired by the multichannel imaging system. The method comprises the following steps: selecting training samples with most similar camera response values from the training sample to-be-selected set for each to-be-reconstructed sample in the to-be-reconstructed sample set respectively to obtain an initially-selected sample set; removing identical samples, and constructing a matrix by the spectral reflectivity information of all samples to perform PCA (Principal Component Analysis) analysis; computing the accumulating contribution rate of a characteristic value; screening the samples to obtain a training sample sub-set, performing spectrum reconstruction according to each training sample sub-set for each to-be-reconstructed sample, and selecting one reconstruction result according to a reconstruction error minimum principle for serving as the final spectral reflectivity value of each to-be-reconstructed sample. By adopting the spectrum reconstruction method and system, the chromaticity accuracy and spectrum accuracy of each reconstructed sample can be remarkably increased, and high-fidelity color reproduction can be performed. Meanwhile, the method and the system are easy and convenient to implement, and are suitable for popularization and application.

Elliptic curve cryptosystem based on identity

The invention relates to an elliptic curve cryptosystem based on an identity. The system comprises a pseudo public key, a pseudo digital certificate, an ECC key generation system, a pseudo digital certificate issuing system, a pseudo digital certificate issuing client-side, a crypto module and a crypto application program. According to the cryptosystem, the pseudo public key corresponding to one identity corresponds to an ECC public key set and an ECC private key set corresponding to the same identity in the crypto module, and therefore the crypto operation of the pseudo public key is automatically transformed into the operation of using a corresponding public key in the corresponding ECC public key set. The crypto operation of using a private key corresponding to the pseudo public key is automatically transformed into the operation of using a corresponding private key in the corresponding ECC private key set. When no corresponding ECC public key or private key exists, the corresponding ECC public key or private key is automatically acquired through the crypto module. The cryptosystem has part of advantages of an IBC, the crypto operation is easier than that of the IBC, the support of client-side crypto hardware is easily obtained, and the intervention of a user in the key updating process can be reduced.
