Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computer-aided design of automobile circuit, and in particular to a method and system for generating a logic diagram of an automobile circuit system. BACKGROUND

[0002] In the design and development process of a wiring harness system of a vehicle, mainly involved are interface information of electrical parts of the vehicle, a logic diagram of a circuit system, a circuit wiring diagram, three-dimensional data of a wiring harness, a topology diagram of a wiring harness, and a wiring harness diagram.

[0003] There are a large amount of basic information such as electrical part device information, connector information, hole information, and configuration definition in the interface information of the electrical parts of the vehicle, and there are complex logical connection relationships and function definitions between the related holes. However, in the prior art, the logical connection relationships between the electrical parts are often determined by manual methods or by identification methods such as names and function descriptions, which undoubtedly consumes a large amount of manpower, is low in efficiency, and is difficult to guarantee the correctness of the design.

[0004] The logic diagram of the circuit system is a blueprint for the design and development of an automobile wiring harness, and is an important link and bridge between the electrical interface information of the electrical parts of the vehicle and the design of the wiring harness diagram of the vehicle. The logic diagram of the circuit system mainly describes logical information such as all electrical part devices, connector information, hole information, configuration information, grounding, and logical connection relationships between each other, and does not involve physical information such as the topology structure, position and size of the wiring harness, the specific specifications and wire color information of the wires, the mating connector, and the wiring harness segmentation.

[0005] In addition, in the traditional design method, the logic diagram of the circuit system may be omitted to directly design the wiring harness diagram. This method seemingly saves the development cycle of the wiring harness, but often causes missing process data, inconsistent data transmission, design errors, and greatly increases the cost and difficulty of the maintenance of the wiring harness diagram in the later stage. There is also a design method in the automobile industry in which the logic diagram of the circuit system and the circuit wiring diagram are coupled together. This method causes the coupling of the circuit logic design and the wiring harness product design, requires higher for the wiring harness engineers, is not conducive to the decomposition of the design link, and is not conducive to the standardization, process, and modularization of the design of the logic diagram of the circuit system.

[0006] Therefore, there is an urgent need for a method for generating a logic diagram of an automobile circuit system to solve the technical problems of the manual method or the identification method, the missing logic diagram of the circuit system, and the coupled design in the prior art. SUMMARY

DETAILED DESCRIPTION

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] To address the deficiencies of the prior art, the present invention discloses a method for generating a logic diagram of an automobile circuit system. Figure 1 As shown, the following steps are included: Step S1: defining interface information of all electrical parts of the whole vehicle, and associating each basic information in the interface information by ID mode; Step S2: automatically generating electrical part device objects and their corresponding connector objects and hole position objects in the circuit system logic diagram according to the interface information; Step S3: automatically generating logic connection objects and grounding objects in the circuit system logic diagram according to the interface information, and realizing the logic connection between each object to complete the circuit system logic diagram; Among them, each basic information in the interface information includes: electrical part device information, connector information, hole position information and logic connection relationship information.

[0016] In some specific embodiments, step S1: defining interface information of all electrical parts of the whole vehicle, and associating each basic information in the interface information by ID mode; includes the following contents: (1) Define project-related information.

[0017] Among them, the project-related information includes: configuration feature code and project information.

[0018] The configuration feature code includes: feature code index, feature code name, feature code description, etc.; wherein the feature code index is a non-repeating sequential number.

[0019] The project information includes project ID, project name and project description; wherein the project ID is the unique identifier of the project information in the database (other IDs are the same).

[0020] (2) Define each basic information in the interface information of all electrical parts of the whole vehicle to complete the definition of the interface information. When defining the interface information, a unique device ID is assigned to each electrical part device and associated with the corresponding project ID, a unique connector ID is assigned to each connector and associated with the corresponding device ID, a unique hole ID is assigned to each hole and associated with the corresponding connector ID, and a unique relationship ID is assigned to each logic connection relationship and associated with the corresponding hole ID and project ID. In the process of defining the interface information, the configuration code is used to configure and define each basic information by using the simple combination logic of "and", "or" and "not".

[0021] Among them, each basic information in the interface information includes: electrical part device information, connector information, hole position information and logic connection relationship information. The electrical part device information includes: device ID, project ID, device name, load characteristic, static current, device configuration definition and device note. The connector information includes: connector ID, device ID, connector name, device end connector model, device end connector hole quantity, device end connector waterproof, wire harness end connector ID, configuration definition of the connector, and connector remarks; wherein, when defining the wire harness end connector ID, the wire harness end connector ID is selected and determined from a wire harness end connector database (or list) according to the device end connector hole quantity, device end connector waterproof and other information; The hole information includes: hole ID, connector ID, hole name, hole description, rated current, minimum current, maximum current, function definition, configuration definition of the hole, and hole remarks. The logical connection relationship information includes: relationship ID, hole ID, item ID, wire specification requirement, twisted pair, and configuration definition of the relationship.

[0022] In some specific embodiments, step S2: automatically generating the electrical component device object and its corresponding connector object and hole object in the circuit system logic diagram according to the interface information; specifically includes the following contents: Based on a certain project ID, the association relationship between the project ID and the device ID, the association relationship between the device ID and the connector ID, and the association relationship between the connector ID and the hole ID, the electrical component device information corresponding to a certain project, and the connector information and the hole information corresponding to the electrical component device information are obtained; The electrical component device information corresponding to a certain project, and the connector information and the hole information corresponding to the electrical component device information are imported into the circuit system logic diagram, the electrical component device object corresponding to a certain project and its corresponding connector object and hole object are automatically generated, and these objects are manually or automatically placed in the specified area of the circuit system logic diagram according to user requirements.

[0023] In some specific embodiments, step S3: automatically generating the logical connection object and the grounding object in the circuit system logic diagram according to the interface information, and realizing the logical connection between the objects to complete the circuit system logic diagram; including the following contents: According to the hole information and the logical connection relationship information corresponding to a certain project, the logical connection object and the grounding object are generated in the circuit system logic diagram, and the logical connection relationship between the hole objects and between the hole objects and the grounding object is realized through the logical connection object, to complete the circuit system logic diagram.

[0024] Exemplarily, since an electrical component device object and its corresponding hole position object corresponding to a certain project are generated in step S2, based on the hole position information contained in the hole position object, if the function in the hole position information is defined as GND, a logical connection object and a grounding object corresponding to the hole position object are automatically generated in the circuit system logic diagram, and a logical connection between the hole position object and the grounding object in the circuit system logic diagram is realized through the logical connection object; Then, based on a certain project ID and the association between the project ID and the relationship ID, logical connection relationship information corresponding to a certain project is obtained; according to the hole position object, the logical connection relationship information corresponding to a certain project, and the association between the relationship ID and the hole position ID, a logical connection object corresponding to the certain project is automatically generated in the circuit system logic diagram, and the logical connection between the hole position objects in the circuit system logic diagram is realized through the logical connection object; Finally, in the circuit system logic diagram, the wire specification requirements of the logical connection objects are designed and confirmed based on the hole position information corresponding to a certain project to complete the circuit system logic diagram; specifically, the wire specification requirements of the logical connection objects are designed and confirmed based on the hole position information contained in each hole position object (such as rated current, minimum current, maximum current, etc.).

[0025] Among them, it should be noted that the content contained in each object is the same as the corresponding basic information. For example, the electrical part equipment object contains all the content of the electrical part equipment information; the final valid value of the configuration definition of each basic information is the logical "and" combination of the configuration definitions of multiple objects (equipment objects, connector objects, hole objects and logical connection objects).

[0026] Advantages of the present invention: In the process of defining the interface information of all electrical parts of the entire vehicle, project information, electrical part equipment information, connector information, hole position information and logical connection relationship information are associated through ID association, which solves the problems of low efficiency and difficulty in ensuring the correctness of identification methods such as manual methods, names or function descriptions; through the simple combination logic of "and", "or" and "not" of the configuration feature code, rich and diverse configuration definitions of electrical part equipment information, connector information and hole position information are realized.

[0050] It should be noted that each object and the corresponding basic information contain the same content.

[0051] 4. Automatically generating the logic connection object and the ground object in the circuit system logic diagram according to the interface information, and realizing the logic connection between each object, completing the circuit system logic diagram; specifically comprising: Based on the pin information and the pin object corresponding to the project ID_PROJ1 obtained in step 3, if the function definition in the pin information is GND, the logic connection object and the ground object corresponding to the project ID_PROJ1 are automatically generated in the circuit system logic diagram, and the logic connection between the pin object (obtained in step 3) and the ground object in the circuit system logic diagram is realized through the logic connection object. In this embodiment, when the function definitions of the pin objects with pin IDs ID_PIN7 and ID_PIN8, ID_PIN13, ID_PIN18 are GND, they are respectively logically connected with the ground object GND through the logic connection objects NET5, NET6, NET7. As shown in the figure, Figure 4 Pin IDs ID_PIN7 and ID_PIN8, ID_PIN13, ID_PIN18 correspond to pin names DEVICE12-2, DEVICE12-3, DEVICE2-5, DEVICE3-5.

[0052] According to the project ID_PROJ1 query table 6, the logical connection relationship information between the relevant hole position objects corresponding to the project ID_PROJ1 in the above logical connection relationship information is obtained, the logical connection objects corresponding to the hole position objects are automatically generated in the circuit system logic diagram, and the logical connection between the hole position objects in the circuit system logic diagram is realized through the logical connection objects. In this embodiment, the logical connection relationship between the hole position objects and the attribute information of the logical connection relationship are realized through a table; if the "relationship ID" is the same, it represents that the corresponding hole position objects are logically connected together. For example, the hole position objects with the hole position IDs ID_PIN1, ID_PIN9 and ID_PIN14 are connected together through the logical connection object NET1 (the hole position IDs ID_PIN1, ID_PIN9 and ID_PIN14 correspond to the hole position names DEVICE1-1, DEVICE2-1 and DEVICE3-1); the hole position objects with the hole position IDs ID_PIN2, ID_PIN10 and ID_PIN15 are connected together through the logical connection object NET2 (the hole position IDs ID_PIN2, ID_PIN10 and ID_PIN15 correspond to the hole position names DEVICE1-2, DEVICE2-2 and DEVICE3-2); the hole position objects with the hole position IDs ID_PIN3, ID_PIN11 and ID_PIN16 are connected together through the logical connection object NET3 (the hole position IDs ID_PIN3, ID_PIN11 and ID_PIN16 correspond to the hole position names DEVICE1-3, DEVICE2-3 and DEVICE3-3); and the hole position objects with the hole position IDs ID_PIN4 and ID_PIN17 are connected together through the logical connection object NET4 (the hole position IDs ID_PIN4 and ID_PIN17 correspond to the hole position names DEVICE1-4 and DEVICE3-4).

[0053] In the table, the logical connection objects NET1 and NET2 are twisted pairs; and the final effective value of the configuration definition is the logical "AND" combination of the configuration definitions of the device objects, the connector objects, the hole position objects and the logical connection objects. For example, in this embodiment, the logical connection configuration definition of the hole position object ID_PIN3 is "(M200 or M201) AND EH01", and the logical connection configuration definition of the hole position object ID_PIN4 is "(M200 or M201) AND (BQ03 AND M200)".

[0054] 5.

Figure 4 Specifically, the completed circuit system logic diagram includes: According to the hole information (such as rated current, minimum current, maximum current, etc.) contained in each hole site object, the wire specification requirement of the logical connection object is designed and determined.

[0055] For example, as shown in Figure 4 The hole site objects with hole site names of DEVICE1-1, DEVICE2-1 and DEVICE3-1 are connected together through the logical connection object NET1, and the wire specification requirement of the logical connection object NET1 is (>=0.35); Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
