The invention discloses a packaging material detection method and device, and the method comprises the steps: obtaining at least one packaging material image of a packaging material on a transmission device, carrying out the detection of a material identification code image of the at least one packaging material image based on the detection sizes of a plurality of preset material identification codes, and obtaining a detection result of the at least one packaging material image; determining a material identification code image of the packaging material; and the material identification code image is detected, and the material type of the packaging material is determined. On one hand, the material type of the packaging material can be automatically detected by obtaining the packaging material image, monitoring and management of the packaging material can be achieved, human intervention is reduced, on the other hand, through setting of the m shooting devices and the material identification code on the packaging material, the m shooting devices can certainly shoot the material identification code image, and the material identification code can be accurately detected. Therefore, the situation that the material identification code cannot be automatically detected is avoided, and the detection precision of packaging material detection is improved.

The invention discloses a casement window structure in a unit curtain wall. The structure comprises a curtain wall body, curtain wall glass and side window body component, wherein the side window body component is arranged on a side wall hole between the end part of the curtain wall glass and the curtain wall body. The casement window structure in the unit curtain wall is combined with the characteristics of factory processing, quality controllability and strong integrity of the unit type curtain wall, and uses the curtain wall shaping characteristics for designing the casement structure in the side wall hole of the curtain wall; the casement uses a mold opening profile for replacing a traditional structure of double frames and embedded glass, so that the used material types are largely reduced, and the processing procedures are reduced; and the dead weight of the glass is about 4-5 times of the weight of the aluminum frame, so that the dead weight of the window body is largely reduced, the load on hardware is reduced, the service life of opening hardware is prolonged, and the user opening and closing operations are easy and free.

The invention relates to a supply chain platform code management method. A first segment code and a tail segment code are generated based on a supplier code and a demand side code of a material; generating a suffix code based on the material type, and generating a second first segment code based on the delivery time of the material; generating a plurality of intermediate codes based on the transfer stations through which the materials flow; generating a secondary tail section code based on the receiving time of the material; data chaining is completed on the codes formed in the above process based on the block chain technology, after a supply chain is finished, material codes composed of the first segment code, the second first segment code, the intermediate code, the second end segment code, the end segment code and the suffix code are generated, coding can be effectively achieved, and material tracking is achieved based on the codes.
