This invention provides a method, device, electronic device, and storage medium for identifying road debris, belonging to the field of signal processing technology. The method includes: acquiring the original vibration signals corresponding to multiple grating measuring points in a grating array vibration sensing optical cable deployed on the road; determining a first energy for each grating measuring point within a first time window based on the original vibration signal; determining the occurrence time of a debris event within the first time window based on the first energy of each grating measuring point; determining a second energy for each grating measuring point within a second time window, wherein the occurrence time falls within the second time window; and determining the location of the debris on the road based on the second energy. Because the location of the debris is determined based on the energy distribution of multiple grating measuring points within a precise time window, the possibility of false alarms and missed alarms is reduced, improving the accuracy and efficiency of debris identification.

This invention discloses a method for preparing finasteride tablets, relating to the field of pharmaceutical preparation technology. The method includes: preparing a surfactant into an aqueous solution, adding a first-prescription amount of binder to form a binder suspension; premixing finasteride, a filler, a first-prescription amount of disintegrant, and a second-prescription amount of binder to obtain a premixed material; adding the binder suspension to the premixed material for wet granulation to obtain wet granules; drying and sizing the wet granules, then mixing them with a second-prescription amount of disintegrant and lubricant, and compressing the mixture into tablets. This invention, while ensuring rapid tablet release, achieves the production of tablets with suitable hardness and stable properties at a relatively low compression pressure. Furthermore, this invention utilizes non-organic solvents for granulation, significantly improving the stability, safety, and industrial production efficiency of the final product without the addition of non-standard excipients.
