Embodiment Construction
[0061] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.
[0062] Axiom design divides the entire product design process into four domains: Customer Domain, Functional Domain, Physical Domain and Process Domain. The whole product design process is the process of mutual mapping of parameters between two adjacent domains, such as figure 1 shown. The product design process is actually a "Z"-shaped mapping process between the four domains, a process that gradually unfolds from the high-level design abstract concept to the low-level detailed design.
[0063] Hierarchical relationships between functional domains and structural domains, such as figure 2 shown. Designers must analyze product design requirements, determine the total functional requirements of the product and map out the total design parameters, and then decompose them into various sub-functional requirements and corresponding design paramet...

The invention relates to a method for quickly determining a low-voltage motor protection device, which comprises the following steps: on the basis of axiomatization theory, dividing function models of the low-voltage motor protection device to obtain a coupling-free or decoupling relationship matrix meeting design requirements; on the basis of a fuzzy cluster analysis method, mapping user requirements to the function models to obtain a relationship characteristic matrix; on the basis of module examples, reasoning the configuration of the low-voltage motor protection device, and setting up a product example search library; by applying a parameterization technology and utilizing dimension constraint and product device key identifiers, parameterizing a universal circuit model of the low-voltage motor protection device; calculating a low-voltage motor inverse time limit protection time parameter and timely carrying out protection actions; and searching the product example search library according to the user requirements to obtain corresponding information models for the low-voltage motor protection device or modifying product example search. The method meets the various user requirements, and simultaneously uses the designed existing process in the product design process so as to reduce the design expense and the production cycle.
