Description

Engineering machinery electronic and electric architecture design method, device and system Technical Field The invention relates to a method, a device and a system for designing an engineering mechanical electronic and electric architecture, and belongs to the technical field of engineering. Background Along with the development of engineering machinery intellectualization and dynamization, the electronic and electric architecture of the invention is increasingly complex. For example, the excavator is taken as an example, tens of types of machine types suitable for different working conditions of mines, municipal administration, forestry and the like are needed to be derived from the same basic platform, and a large number of configuration variants exist in the aspects of power systems (diesel oil, pure electricity, mixed power), intelligent grades (auxiliary excavation, one-key land leveling, unmanned), working devices (bucket, breaking hammer, hydraulic shear) and the like. The current mainstream design method of the electronic and electric architecture in the engineering machinery industry has obvious pain points: Document-based variant management, in which an Excel table management function is relied on to manage configuration and an ECU list, and architectural design (logic, network and physical) is separated from the configuration list. Any configuration change needs engineers to manually modify a large number of documents such as system requirement specifications, network communication matrixes, schematic diagrams and the like one by one, has low efficiency, is extremely easy to make mistakes, and is difficult to ensure consistency among the documents. Post screening based on redundancy model as disclosed in patent CN202110846250.7, a "150%" or "super" architecture model containing all possible functions is created in PREEvision etc. tools, and then the required parts are screened out for each specific model by means of "mark-activate". This approach results in a model that is bulky and heavy, and when the underlying platform is upgraded, all preset variants need to be manually adjusted, with high maintenance costs, essentially for the post-management of the "design effort" rather than for the optimization of the "design process". Design reusability is poor and knowledge is lost, and excellent subsystem designs (such as intelligent thermal management systems) are strongly coupled with specific model configurations, so that the design is difficult to multiplex as independent assets to a new platform. Design knowledge is dispersed in documents and models of different engineers and cannot be effectively deposited and reused. Therefore, there is a strong need in the art for a flexible design approach that enables decoupling from the design source, supporting automatic derivation of a specific model architecture through configuration drivers. Disclosure of Invention The invention aims to provide a design method, a device and a system for an engineering mechanical electronic and electric architecture, which realize automatic generation from an abstract template to a specific example through a derivation engine by uniformly abstracting, packaging and managing all variability in the electronic and electric architecture, so as to solve the problems of difficult design change, rough modification management, poor consistency, low reusability and the like in the traditional method and realize the fundamental conversion of a design paradigm from 'later screening' to 'earlier derivation'. In order to achieve the above purpose/solve the above technical problems, the present invention is realized by adopting the following technical scheme. In one aspect, the present invention provides a method for designing an engineering mechanical electronic and electrical architecture, including: identifying and defining all the variable points in the electronic and electric architecture, abstracting each variable point into a configuration element in a unified form, and constructing a configuration element library; creating a parameterized seed model of the electronic and electric architecture, and establishing an association mapping relation between model elements in the parameterized seed model and configuration elements in the configuration element library; Selecting required configuration elements from the configuration element library according to the specification requirements of the target machine type, assigning values for parameters of the configuration elements, and generating a configuration list of the target machine type after automatic verification of dependence and constraint rules among the configuration elements; Reading a configuration list of the target model by a deduction engine, accessing all affected model elements in the parameterized seed model according to the association mapping relation, dynamically calculating and determining the final state and attribute of each affected model element according to
