The intelligent terminal is used to clarify the apartment decoration screening target according to the apartment type and customer needs, establish a structured data model for the apartment decoration wishes selected by the customer, capture the design scheme related to the apartment decoration conditions selected by the customer in the data sharing and exchange platform, and associate it with the customer willingness collection module, load the screened design scheme into the design drawing pre-selection module page, and the intelligent terminal sends the screened design scheme data to the terminal design drawing encryption module to decrypt the screened design scheme; The terminal design drawing encryption module includes a final draft design drawing encryption module and a design drawing decryption module. The design drawing decryption module is used to decrypt the design drawings stored in the data sharing and exchange platform to achieve security management and control of the design drawing data. According to the preset program, the identity authentication and key verification are performed on the customer. The identity authentication includes identity card verification and face recognition. Face recognition includes collecting the horizontal and vertical positioning points of the eyes and the nose tip, establishing a three-dimensional coordinate model, taking the lips as the center, setting the horizontal positioning point of the eye to (X1, Y1), and setting the vertical positioning point of the nose tip to (Y2, Z1). When Y1>5cm and Z1>3cm are satisfied, it is determined to be a normal face. When the above formula is not satisfied, it is determined to be an abnormal face. The key verification is used to input through the specified key, so that monitoring is performed when the key is input, and a trace is left during the access. After the data sharing and exchange platform verifies the access key, the design drawings related to the apartment decoration conditions selected by the customer are sent to the design drawing pre-selection module; The rendering scheme presentation module has a VR imaging module inside. The designer imports the design drawings selected by the customer, modifies them according to the customer's design requirements, adds or deletes the design drawings, and sends the modified design drawings to the customer for confirmation. The confirmation categories include design drawings and decoration material quotations. The decoration material quotations include decoration material categories and material selling prices. The material selling price is set to K, the material inventory quantity of the factory is set to C1, the historical purchase price is set to R1, the sales price of the latest batch of decoration materials is set to R2, and the purchase quantity is set to C2. The formula for calculating the sales price of the current decoration material is: K=(R2*C2+R1*C1) / (C1+C2) According to the calculated material selling price K, the decoration material quotation is (1+10%) K, and the decoration material quotation is sent to the user for confirmation. When the design drawings and decoration material quotation are all confirmed, the design drawings are entered into the VR imaging module. The VR imaging module is used to perform VR imaging on the design drawings, so that customers can view the design drawings in a more detailed and three-dimensional manner; The data sharing and exchange platform includes a database and a data security determination module. The database is used to store design drawings, and each design drawing is numbered, and each design drawing corresponds to only one number. The data security determination module performs security determination on newly stored design drawings.
