Publication number: 20230353390Abstract: A method for upgrading a certificate of a POS terminal, a server, a POS terminal and a terminal device are provided, this method includes: performing a mutual authentication with the POS terminal when receiving a certificate upgrading request sent from the POS terminal; and encapsulating the certificate to be upgraded in a preset proprietary protocol format to obtain update data, using a session key to encrypt the update data to obtain a ciphertext and sending the ciphertext to the POS terminal, after the mutual authentication is passed. According to the present application, a problem that it is inconvenient to use the existing certificate update methods, much time needs to be consumed, and transportation cost is increased may be solved.Type: ApplicationFiled: November 7, 2019Publication date: November 2, 2023Inventors: Chuanxi WANG, Dong ZHOU, Zhenwei SUN, Saifeng DENG

Publication number: 20230021275Abstract: The disclosure discloses application of nanosulfur in tomato fusarium wilt control, belonging to the technical field of novel pesticides. The application of the disclosure includes the following steps: preparing a nanosulfur solution from nanosulfur; and then soaking seeds in the nanosulfur solution or applying the nanosulfur solution onto tomato foliage, and continuing cultivation to obtain tomato plants. The nanosulfur has a particle size of 20-150 nm. The nanosulfur solution uses water as a solvent and has a concentration of 30-200 mg/L. According to the disclosure, after the tomato plants are treated with the nanosulfur by foliar spraying, the fresh weight of the above-ground part is 1.05 times or more that of the disease group, and the fresh weight of the underground part is 1.05 times or more that of the disease group, so that the incidence of tomato fusarium wilt is reduced by 8% or more.Type: ApplicationFiled: September 21, 2022Publication date: January 19, 2023Inventors: Zhenyu WANG, Xuesong CAO, Chuanxi WANG, Le YUE

Patent number: 11445728Abstract: The present disclosure discloses an application method of silicon quantum dots (Si QDs) for controlling corn armyworm, belonging to the technical field of nano-agricultural technology for crop pest control. The method for controlling corn armyworm by using Si QDs of the present disclosure includes the following steps of: preparing the Si QDs into an aqueous solution of the Si QDs, and then applying the aqueous solution on the roots or leaves of plants as plant fertilizer; where the concentration of the aqueous solution of the Si QDs is 10-150 mg/L; the size of the Si QDs is 3-8 nm. The method of the present disclosure not only improves the effect of the conventional silicon fertilizer on the stress resistance of plants, but also directly improves the direct insecticidal effect of the nano-silicon and improves the chemical defense capability of plants; the optimal spraying amount of Si QDs is determined by spraying different concentrations of Si QDs in the growth and development experiment of armyworm.Type: GrantFiled: December 14, 2021Date of Patent: September 20, 2022Assignee: JIANGNAN UNIVERSITYInventors: Zhenyu Wang, Zhenggao Xiao, Chuanxi Wang, Le Yue

Patent number: 11401913Abstract: The disclosure proposes a yaw calibration method and system for a wind turbine. The calibration method includes: establishing a cylindrical coordinate graph of wind resource distribution based on historical wind farm operation data, to determine a wind direction interval of main inflow wind conditions of a wind farm; calculating an effective value of active power of each wind speed sub-interval, and obtaining a fitted power curve of each refined interval through curve fitting; and setting an angle between a central axis of a refined interval for a fitted power curve corresponding to a calibration curve in each wind speed range and a central axis of the to-be-calibrated wind direction interval as a yaw error calibration value in the wind speed range, to establish a wind speed-yaw error calibration value lookup table; and determining a yaw error calibration value under a current wind direction and a current wind.Type: GrantFiled: November 11, 2020Date of Patent: August 2, 2022Assignees: North China Electric Power University, Guodian New Energy Technology Research Institute Co., Ltd.Inventors: Zhongwei Lin, Chenzhi Qu, Chuanxi Wang, Zhenyu Chen, Xiangyu Han, Zhen Xie, Qingru Cui, Gengda Li, Xiongwei Li
