It should be noted that, for the electrical modularization of the existing product of the locomotive, the electrical function and component structure information thereof may be limited by the parameters of the existing product when being obtained, such as the type of the component, the code number of the component, etc. are fixed, so that the degree of freedom of the electrical modularization of the existing product finally obtained is relatively small, but the modularization result may still cover all the mechanical and electrical characteristics of the existing product. For the electrical modularization of the new product, the corresponding electrical function and component structure information can be based on the existing product parameters but can not be completely limited by the existing product parameters, for example, for a certain electrical function (preheating), the configurable component type and the like can be selected and set by workers according to the actual situation, so that the range of the corresponding electrical function and component structure information of the new product is wider when the corresponding electrical function and component structure information of the new product is obtained, the degree of freedom of the electrical modularization structure of the finally obtained new product is larger, and the established modularization structure is more flexible.
In an exemplary embodiment of the present disclosure, the determining of the electrical function information of the locomotive in the step S100 includes the steps of:
step S110, collecting the existing electrical function information of the locomotive;
and step S120, determining comprehensive electrical function information of the locomotive according to the existing electrical function information of the locomotive and by combining the user demand and the future demand prediction.

In step S120, the comprehensive electrical function information of the locomotive is determined according to the existing electrical function information of the locomotive, and by combining the user demand and the future demand prediction. For example, according to the user demand and the future market demand prediction, a new electric function or other functions which are possibly required in the future are added on the basis of the existing electric function, and the comprehensive electric function of the locomotive is obtained.
It should be noted that, for the electrical modularization of the existing product of the locomotive, the comprehensive electrical function corresponding to the existing product of the locomotive is determined according to the existing electrical function information, the requirements of the existing user and the future prediction. For the electrical modularization of the new locomotive product, the corresponding comprehensive electrical function of the new locomotive product is determined based on the existing electrical function information and by combining the requirements of new users and future prediction.
And step S200, dividing the electrical equipment into a plurality of sub-equipment modules according to the electrical equipment information of the locomotive.
The electrical equipment of the locomotive refers to hardware equipment required for integrating electrical components and the like in the locomotive, such as a cabinet and a top cover for integrating the electrical components, and wiring for connecting the various cabinets or the top covers. Other hardware devices which are not belonging to the screen cabinet or the top cover but are still required for integrating the electrical components are classified as supplementary devices, such as supplementary boxes for supplementing and adding the electrical components. Wherein, screen cabinet and top cap quantity are a plurality of, and specific number is decided by the locomotive product.
In an exemplary embodiment of the present disclosure, step S200 includes:
step S210, determining the equipment attribute of the electrical equipment of the locomotive; the equipment attributes comprise a screen cabinet attribute, a top cover attribute, a supplementary equipment attribute and a wiring attribute;
step S220, according to the device attributes, the electrical device is divided into electrical device modules including a cabinet module, a top cover module, a supplementary device module, and a wiring module.
In step S210, the electrical device attributes refer to the classification of the electrical devices such as integrated electrical components on the mechanical types of the products, such as the cabinet, the top cover, and the circuit. In this embodiment, the screen cabinet is classified as a screen cabinet module, the top cover is classified as a top cover module, and other supplementary boxes not belonging to the screen cabinet and the top cover are classified as supplementary equipment modules, and the lines for realizing electrical connection are classified as wiring modules. The number of the screen cabinet modules, the number of the top cover modules, the number of the supplementary equipment modules and the number of the wiring modules can be multiple, and the screen cabinet modules, the top cover modules, the supplementary equipment modules and the wiring modules can be divided into multiple stages based on the difference of each product of the locomotive. The screen cabinet module, the top cover module, the supplementary equipment module and the wiring module can be divided into a screen cabinet module 1, a screen cabinet module 2 and a screen cabinet module 3 according to the number, the content is high, and the screen cabinet module N is high; a header module 1, a header module 2, a header module 3, ·.., and a header module N; a wiring module 1, a wiring module 2, a wiring module 3, a wiring module N; a supplemental device module 1, a supplemental device module N, etc. In addition, the screen cabinet module, the top cover module, the supplementary equipment module and the wiring module can be divided into a plurality of stages in other modes, for example, the screen cabinet module, the top cover module, the supplementary equipment module and the wiring module can be divided into two stages according to functions, for example, the screen cabinet module is divided into a high-voltage cabinet module and a direct-current cabinet module. Further, each of the cabinet module, the top cover module, the wiring module or the supplementary equipment module may be provided with an expansion space for adding new electrical components in the following. Of course, new electrical components may also be added by adding new cabinet modules, header modules, wiring modules, or supplemental equipment modules.
And step S300, dividing the comprehensive electrical function into a plurality of sub-function modules according to the comprehensive electrical function information of the locomotive.
The electric function of the locomotive refers to functions possessed by the operation of the locomotive, such as lighting control, auxiliary machine (compressor, fan, air conditioner and the like) control, variable flow control, 6A system control and the like. The comprehensive electrical function is divided into a plurality of sub-functional modules, and the modularization of the electrical function is realized.
In an exemplary embodiment of the present disclosure, step S300 includes:
step S310, acquiring the application range of the comprehensive electrical function, and defining the functional attributes corresponding to the comprehensive electrical function of the locomotive, wherein the functional attributes comprise basic attributes, general attributes and special attributes;
step S320, according to the function attributes, the integrated electrical function is divided into electrical function modules including a basic function module, a general function module, and a dedicated function module.
The electrical functions with basic properties are divided into basic function modules, the electrical functions with general properties are divided into general function modules, and the electrical functions with special properties are divided into special function modules.
In step S310, the application range of the integrated electrical function refers to the application range of the electrical function to different models of locomotives.
In an exemplary embodiment of the present disclosure, step S310 includes:
step S311, if the comprehensive electrical function is the electrical function shared by locomotives of different models, defining the comprehensive electrical function as a basic attribute;
step S312, if the comprehensive electrical function is suitable for locomotives of different models and the configured component structure information has uniqueness, defining the comprehensive electrical function as a general attribute;
and step S313, if the comprehensive electrical function is only suitable for the locomotive with the determined model, defining the comprehensive electrical function as the special attribute.
In step S311, the electrical function common to the different models of locomotives refers to an electrical function required for the different models of locomotives. Such as lighting control and auxiliary machinery control, are electrical functions required for each model of locomotive. In an exemplary embodiment, when the logic control, the component code and the signal definition corresponding to the electrical function have uniqueness, and the specific component model has diversity, the electrical function is defined to have basic properties. The logic control mainly refers to a control circuit which is designed according to requirements according to a certain method and steps by considering the logic relation of the control circuit. The component number refers to a number marked on a basic component or the like in an electrical system or electrical equipment to distinguish different functions, states and characteristics of the electrical equipment and lines, for example, SA denotes a control switch, SB denotes a push button switch, TR denotes a rectifier transformer, and the like. The component model refers to the model corresponding to a specific electrical component. For the locomotive lighting control function, locomotives of different models have the lighting function, and the logic control, the part code number and the signal definition for realizing the lighting function are determined and unique, but the models of lighting lamps adopted by the locomotives of different models can be different.
In step S312, the configuration information of the components that are applicable to different models of locomotives and configured is unique, which means that the electrical function can be used for other models of locomotives without any modification or adjustment. The component structure information refers to that the model number, the code number and the like of the component are all unique. In an exemplary embodiment, when the logic control, the component model number, the component code number and the signal definition corresponding to the electrical function have uniqueness, the electrical function is defined to have a general attribute. For example, the vehicle-mounted safety protection system of the locomotive, 6A system, the logic control, the part model, the part code and the signal definition of the system have uniqueness, the system can be suitable for locomotives of different models without any adjustment, and the attribute of the electrical function is the universal attribute.
In step S313, the fact that the electric function is applicable only to the specific model of the locomotive means that the electric function is applicable only to one specific model of the locomotive. Such as the preheating function of an eight-axle locomotive.
In step S320, the integrated electrical function is divided into electrical function modules including a basic function module, a general function module, and a dedicated function module according to the function attributes.
In the present disclosure, the functional attribute definitions are divided according to an independence principle, a simplification principle, a commonality principle, and an overall optimization principle. The independence means that the coupling degree of information, functions and the like among the modules is as small as possible, and the influence degree among the modules is reduced to the minimum; simplification means that module hierarchies and structures in modules are reduced as much as possible, and functions with high association degree are directly put into the same module; the universality means that functions with general attributes are arranged in one module and are designed into a general function module; the overall optimization principle refers to standing at an overall angle, combining with overall layout and taking other division principles into overall consideration.
In an exemplary embodiment of the present disclosure, step S300 further includes:
step S330, dividing the basic function module into an inherent basic unit and an extended basic unit, determining the inherent basic unit according to the existing electrical function information and the user requirement of the locomotive in the basic function module, and determining the extended basic unit according to the existing electrical function information of the locomotive in the basic function module and by combining the user requirement and the future requirement prediction;
step S340, dividing the universal function module into an inherent universal unit and an extended universal unit, determining the inherent universal unit according to the existing electrical function information and the user requirement of the locomotive in the universal function module, and determining the extended universal unit according to the existing electrical function information of the locomotive in the universal function module and the user requirement and future requirement prediction;
and S350, dividing the special function module into an inherent special unit and an extended special unit, determining the inherent special unit according to the existing electrical function information and the user requirement of the locomotive in the special function module, and determining the extended special unit according to the existing electrical function information of the locomotive in the special function module and the user requirement and future requirement prediction.
In step S330, an intrinsic basic unit is determined according to the locomotive existing electrical function information and the user requirement in the basic function module, and an extended basic unit is determined according to the locomotive existing electrical function information in the basic function module, and the user requirement and the future requirement prediction are combined.
In the above steps, each functional module has an inherent unit and an extended unit, where the basic functional module includes an inherent basic unit and an extended basic unit, the general functional module includes an inherent general unit and an extended general unit, and the specific functional module includes an inherent specific unit and an extended specific unit. The inherent unit is a unit which can be determined at the present stage, and the extended unit is a possible unit which is reserved in consideration of future market demands and development. The extension unit can comprise a function extension and a component extension, for example, the extension base unit can comprise a function extension of an electrical function, for example, in a base function module, the lighting function belongs to an inherent base unit except for an existing lighting function, and a future possible function can be reserved, and the part of the function belongs to the extension base unit. Of course, the extension base unit may also include component extensions of components configured in the existing electrical function, such as extensions of specific components that need to be configured in the lighting function.
In step S400, corresponding component structures are arranged for the plurality of sub-function modules based on the arrangement relationship between the integrated electrical function of the locomotive and the component structures of the locomotive.
In this step, the component structure includes specific component names, codes, models, etc., such as switch-on lights, headlamps, undercarriage lights, road condition cameras, detection sensors, etc., and locomotive components bearing the component, such as a console, a cab roof, a bogie, an undercarriage, etc.
In step S500, a locomotive architecture platform including an electrical equipment module and an electrical function module is established, where the electrical equipment module includes a plurality of sub-equipment modules, and the electrical function module includes a plurality of sub-function modules.
As shown in fig. 2, in an exemplary embodiment of the present disclosure, the locomotive electrical modularization method further comprises:
step S600, an interface protocol module is established according to the connection mode among the plurality of sub-equipment modules.
In this step, the connection between the modules is specifically referred to, and the connection inside the modules is not referred to. In an exemplary embodiment of the present disclosure, step S600 includes:
step S610, dividing the interface protocol module into a mechanical interface module and an electrical interface module;
step S620, determining a mechanical interface module according to a wiring connection mode among a plurality of sub-devices;
step S630, determining an electrical interface module according to the electrical signal connection mode among the multiple pieces of sub-equipment.
The mechanical interface module is a module divided according to line connection, and the electrical interface module is a module divided according to electrical signal connection.
In an exemplary embodiment of the present disclosure, step S620 includes:
step S621, dividing the mechanical interface module into a fixed mechanical interface unit and an extended mechanical interface unit;
step S622, determining a fixed mechanical interface unit according to the existing wiring connection mode among the plurality of sub-equipment modules;
step S623, predicting a future wiring connection manner between the plurality of sub-device modules to determine an extended mechanical interface unit.
In the above steps, the fixed mechanical interface unit has a definite specification of the plug connector, an interface size, an installation mode and the like, and the extended mechanical interface unit is an interface space reserved according to an extended function.
