Real-time pushing processing method of product design document data on the basis of brain-computer interaction

Abstract

The invention discloses a real-time pushing processing method of product design document data on the basis of brain-computer interaction. A product design process is decomposed into different design nodes, a product design document is searched and associated according to the node characteristic information of different design nodes to form a product design database, and the electroencephalogram signal of a designer is monitored and analyzed in real time to judge whether the designer is under the requirement state of the product design document or not so as to push the product design document; according to the browsing behavior of the designer, requirement domain data and domain characteristic documents are obtained and are added into a database; then, when a certain design node is met and the requirement state is detected, all domain characteristic documents in the demand domain data corresponding to the design node are pushed according to an order of priority; and domain unfolding pushing or domain characteristic document replacement is carried out. The real-time pushing processing method can identify the requirements of the product design document, realizes the intelligent pushing of the data of the product design document, saves the time and the vigor of manual work and improves efficiency.

Description

technical field [0001] The invention belongs to the technical field of computer-aided design, brain-computer interface and human-computer interaction, and in particular relates to a real-time push processing method of product design document data based on brain-computer interaction. Background technique [0002] In the field of complex mechanical product design, due to the characteristics of intensive knowledge, designers need to frequently search for product design documents. Research shows that in the product design process, 60% of the time is used to search for product-related design documents, which seriously restricts Improvement in design efficiency. With the informatization of the manufacturing industry deepening, the number of product design documents is growing explosively. How to make designers quickly obtain the product design documents they need has become one of the research hotspots in the field of computer-aided design. [0003] In view of the above problems,...

Problems solved by technology

However, the current push technology still requires the designer to actively provide information when obtaining user needs, or only infers through design tasks. The former still requires the designer to operate passively, while the latter has vague demand judgments and low intelligence because no direct information is obtained. , the push effect is poor
