Description

Technical Field

[0001] The present invention relates to the technical field of automobile wiring harnesses, and provides a method for quickly detecting the connection integrity of wiring harness conductors, a computer-readable storage medium, and electronic equipment. Background Art

[0002] Wiring harness systems play a vital and irreplaceable role in the realization of electrical functions in vehicles such as automobiles and aircraft. As electrical devices become more and more numerous and their electrical functions become more and more diverse, wiring harness systems have become larger and more complex, and the number of wires has also increased.

[0003] In wiring harness design, for a given logical connection, multiple wires and multiple wire contacts may be required to connect the terminals of the connector together to achieve the corresponding physical connection. Wire connection integrity means that multiple wires corresponding to the same logical connection are connected end-to-end through wire contacts to ensure that all corresponding terminals are fully connected. There should be no unconnected terminals, isolated, or redundant wires. Wire connection integrity is the fundamental prerequisite for achieving electrical functionality and is the most basic requirement for wiring harness design.

[0004] Complex wiring harness systems have numerous logical connections, corresponding to 1,000 or more wires. Manually checking the integrity of each wire connection individually is labor-intensive, inefficient, and difficult to guarantee accuracy. Summary of the Invention

[0005] The present invention provides a method for quickly detecting the integrity of a wiring harness wire connection, aiming to realize automatic detection of the completeness of the wiring harness wire connection.

[0006] The present invention is implemented as follows: a method for quickly detecting the integrity of wiring harness wire connections, the method specifically comprising the following steps:

[0007] S1. Define the wire contacts and terminals in the wiring harness diagram as target objects, and build a target object list for each target object;

[0008] Target objects are classified into terminal and non-terminal types. For terminal type targets, if the number of connections is greater than 0, the target object is considered to have completed the connection. For non-terminal type targets, if the number of connections is greater than 1, the target object is considered to have completed the connection; otherwise, the target object is considered to have not completed the connection.

[0009] S2. Before each connection operation, perform a redundancy check on the current connection wire. If the current connection wire is not a redundant connection, perform a connection operation on the two target objects at both ends of the wire.

[0010] S3. After all wires are connected, check the integrity of the wire connections in the wiring harness diagram.

[0011] Furthermore, the current redundancy detection method of the connecting wires is specifically as follows:

[0012] Check whether the two target objects of the current connecting wire are in the same target object list. If the detection result is no, the current connecting wire is not a redundant connection. If the detection result is yes, the current connecting wire is a redundant connection.

[0013] Furthermore, the connection operation process of the two target objects at both ends of the wire is as follows:

[0014] The target object lists of the two target objects of the current wire to be connected are merged, thus completing the connection of the current wire.

[0015] Furthermore, the method for merging the target object list is as follows:

[0016] Merge the target object list with fewer target objects into the two target object lists with more target objects.

[0017] Furthermore, when both target objects are terminals or wire contacts, the target object list with fewer target objects is merged into the target object list with more target objects. When the two target objects are a terminal and a wire contact, the target object list of the terminal is merged into the target object list of the wire contact.

[0018] Furthermore, the integrity detection method of the wire connection in the wiring harness diagram is as follows:

[0019] Check whether the number of target objects in the list is 1 and all target objects have been connected. If the test result is yes, the wire connections in the wiring harness diagram are complete. If the test result is no, the wire connections in the wiring harness diagram are incomplete.

[0020] Furthermore, after the target object lists of the two target objects of the current connection wire are merged, the method further includes:

[0021] Update the number of connections i of the two merged target objects, set i = i + 1. After all wire connections are completed, the terminals with a connection number of zero and the wire contacts with a connection number of less than 2 are incompletely connected terminals and wire contacts.

[0022] The present invention is implemented as follows: a computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, it implements any of the above-mentioned methods.

[0023] The present invention is implemented as follows: an electronic device includes a processor and a memory;

[0024] The memory is used to store computer programs;

[0025] The processor is configured to implement any of the above methods when executing the program stored in the memory.

[0026] Add terminals and wire contacts as target objects to the Target Object Manager. Then, through the "Connect" operation of the Target Object Manager, the integrity of wire connections and redundant wire connections are automatically detected. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The specific implementation of the present invention will be further explained in detail below by describing the best embodiment with reference to the accompanying drawings.

[0032] Figure 1 A flowchart of a method for quickly detecting the integrity of wiring harness wire connections provided by an embodiment of the present invention, the method specifically includes the following steps:

[0033] S1. Define the wire contacts and terminals in the wiring harness diagram as target objects, and construct a target object list for each target object, where the target object type corresponding to the wire contacts is a non-terminal type, and the target object type corresponding to the terminals is a terminal type;

[0034] Obtain the wiring harness diagram corresponding to the current logical connection relationship, determine the wire identifier of each wire in the wiring harness diagram and the wire contacts and terminals connected at both ends. The two ends of the wire can be connected to two wire contacts, two terminals, or one wire contact and one terminal. The two ends of the wire contact are connected to the wire contacts or terminals through wires, and the terminals are the endpoints of the main line or branch line in the wiring harness diagram.

[0035] S2. Before each connection operation, perform a redundancy check on the current connection wire. If the current connection wire is not a redundant connection, perform a connection operation on the two target objects at both ends of the wire.

[0036] In an embodiment of the present invention, the current redundancy detection method for connecting wires specifically includes the following steps:

[0037] Check whether the two target objects of the current connecting wire are in the same target object list. If the detection result is no, the current connecting wire is not a redundant connection. If the detection result is yes, the current connecting wire is a redundant connection, then mark the current connecting wire or exit the current program.

[0038] If the current connecting wire is not a redundant connection, the connection operation of the two target objects at both ends of the wire is performed. The connection operation is as follows:

[0039] The target object lists of the two target objects of the current wire to be connected are merged, thus completing the connection of the current wire.

[0040] In an embodiment of the present invention, a method for merging two target objects at both ends of a wire is specifically as follows:

[0041] Merge the target object list with fewer target objects into the target object lists with more target objects. That is, when both target objects are terminals or wire contacts, merge the target object list with fewer target objects into the target object lists with more target objects. When the two target objects are a terminal and a wire contact, merge the target object list for the terminal into the target object list for the wire contact.

[0042] S3. After all wires are connected, check the integrity of the wire connections in the wiring harness diagram.

[0043] In an embodiment of the present invention, the method for detecting the integrity of a wire connection specifically includes the following steps:

[0044] Check whether the number of target objects in the list is 1 and whether all target objects have been connected. If the test result is yes, the wire connections in the wiring harness diagram are complete. If the test result is no, the wire connections in the wiring harness diagram are incomplete.

[0045] In an embodiment of the present invention, in order to quickly determine the incompletely connected wire contacts and terminals, after merging the target object lists of the two target objects at both ends of the current connecting wire, the following steps are further performed:

[0046] Update the number of connections i of the two merged target objects, that is, i = i + 1. After all wire connections are completed, the terminals with a connection number of zero and the wire contacts with a connection number of less than 2 are incompletely connected terminals and wire contacts.

[0047] An embodiment of the present application provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program. When the computer program is executed by a processor, the method for quickly detecting the integrity of any of the wiring harness wire connections is implemented.

[0048] An embodiment of the present application provides an electronic device, including a processor and a memory;

[0049] The aforementioned memory is used to store computer programs;

[0050] The processor is used to implement any of the above-mentioned methods for quickly detecting the integrity of the connection of the wire harness when executing the program stored in the memory.

[0051] The above-mentioned processor can be a general-purpose processor, including a CPU (Central Processing Unit), an NP (Network Processor), etc.; it can also be a DSP (Digital Signal Processing), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array) or other programmable logic devices, discrete gate or transistor logic devices, and discrete hardware components.

[0052] In the above embodiments, it can be implemented in whole or in part by software, hardware, firmware or any combination thereof. When implemented using software, it can be implemented in whole or in part in the form of a computer program product. The computer program product includes one or more computer instructions. When the computer program instructions are loaded and executed on a computer, the process or function described in the embodiment of the present application is generated in whole or in part.

For example, the computer instructions can be transmitted from one website, computer, server or data center to another website, computer, server or data center via a wired (e.g., coaxial cable, optical fiber, digital subscriber line) or wireless (e.g., infrared, wireless, microwave, etc.) method. The computer-readable storage medium can be any available medium that a computer can access or a data storage device such as a server or data center that includes one or more available media integrated. The available medium can be a magnetic medium (e.g., a floppy disk, a hard disk, a tape), an optical medium (e.g., a DVD), or a semiconductor medium (e.g., a solid-state drive SolidState Disk (SSD)).

[0053] Figure 3 A simplified schematic diagram of a wiring harness diagram provided in an embodiment of the present invention, wherein each section is a trunk or branch of a wiring harness, A, B, C, D, E, F and G are all terminals corresponding to a certain logical connection relationship, and S1, S2 and S3 are wire contacts corresponding to the logical connection relationship; the wire schematic diagram corresponding to the logical connection relationship is shown in FIG. Figure 4 As shown, WIRE1, WIRE2, WIRE3, WIRE4, WIRE5, WIRE6, WIRE7, WIRE8 and WIRE9 are all wires corresponding to the logical connection relationship;

[0054] The two ends of WIRE1 are connected to terminal A and wire contact S1; the two ends of WIRE2 are connected to terminal B and wire contact S1; the two ends of WIRE3 are connected to terminal C and wire contact S1; the two ends of WIRE4 are connected to terminal D and wire contact S2; the two ends of WIRE5 are connected to terminal E and wire contact S2; the two ends of WIRE6 are connected to wire contacts S1 and S2; the two ends of WIRE7 are connected to terminal F and wire contact S3; the two ends of WIRE8 are connected to terminal G and wire contact S3; the two ends of WIRE9 are connected to wire contact S1, wire contact and S3.

[0055] This embodiment uses the logic relationship to connect the terminals together through the wires and wire contacts to calculate the wire connection integrity as an example.

[0056] (1) Defined as target object.

[0057] Define all corresponding terminals and wire contacts as target objects: target object A, target object B, target object C, target object D, target object E, target object F, target object G, target object S1, target object S2, and target object S3. Target objects A, B, C, D, E, F, and G are terminal types, while target objects S1, S2, and S3 are non-terminal types. The default connection count for all target objects is 0.

[0058] (2) Initialization of the target object manager.

[0059] Add all the above target objects to the target object manager (i.e., the processor in the electronic device). When adding target object A, the target object manager will create an empty target object list 1, add target object A to the newly created target object list 1, and then add the newly created target object list 1 to the target object manager. This process is repeated in this way until the target object manager is initialized. The result is as follows:

[0060] Target object list 1: target object A (connected times 0); target object list 2: target object B (connected times 0); target object list 3: target object C (connected times 0); target object list 4: target object D (connected times 0); target object list 5: target object E (connected times 0); target object list 6: target object F (connected times 0); target object list 7: target object G (connected times 0); target object list 8: target object S1 (connected times 0); target object list 9: target object S2 (connected times 0), target object list 10: target object S3 (connected times 0).

[0061] (3) The target object manager performs a "connect" operation.

[0062] Get all wires WIRE1 to WIRE9 corresponding to the logical connection relationship, loop one by one, and according to the information at both ends of the wire, perform a "connection" operation on the two target objects at both ends of the wire ID for the target object manager.

[0063] The "connect" operation sub-flowchart of the target object manager, such as Figure 2As shown, if the connection between the two ends of a wire is incomplete, the loop exits and outputs the result: "Connection incomplete." If the two target object lists are the same during a wire "Connect" operation, the loop exits and outputs the result: "Connection redundant." If the two target object lists are different, the "Connect" operation is completed for the two target objects with the corresponding IDs in the target object manager.

[0064] The connection operations are as follows:

[0065] 3.1. Based on the information at both ends of wire WIRE1, perform a "connect" operation on the target objects A and S1 corresponding to the target object manager. Increase the number of connections of target objects A and S1 by 1, and then merge target object list 1 into target object list 8. After completing the "connect" operation, the target object manager is as follows:

[0066] Target object list 2: Target object B (connected times 0).

[0067] Target object list 3: Target object C (connected times 0).

[0068] Target object list 4: Target object D (connected times 0).

[0069] Target object list 5: Target object E (connected times 0).

[0070] Target object list 6: Target object F (connected times 0).

[0071] Target object list 7: Target object G (connected times 0).

[0072] Target object list 8: Target object S1 (connected times 1), target object A (connected times 1).

[0073] Target object list 9: Target object S2 (connected times 0).

[0074] Target object list 10: Target object S3 (connected times 0).

[0075] 3.2. Based on the information at both ends of wire WIRE2, perform a "Connect" operation on the target objects B and S1 corresponding to the target object manager. Increase the number of connections of target objects B and S1 by 1, and then merge target object list 2 into target object list 8. (To improve efficiency, the target object list with fewer target objects is merged into the target object list with more target objects, and the same applies below. Therefore, the target object list at the end is generally merged into the target object list of the wire contact. If both target objects are terminals or wire contacts, the target object list with fewer target objects is merged into the target object list with more target objects.) After completing the "Connect" operation, the target object manager is updated as follows:

[0076] Target object list 3: Target object C (connected times 0).

[0077] Target object list 4: Target object D (connected times 0).

[0078] Target object list 5: Target object E (connected times 0).

[0079] Target object list 6: Target object F (connected times 0).

[0080] Target object list 7: Target object G (connected times 0).

[0081] Target object list 8: target object S1 (connected times 2), target object A (connected times 1), target object B (connected times 1).

[0082] Target object list 9: Target object S2 (connected times 0).

[0083] Target object list 10: Target object S3 (connected times 0).

[0084] 3.3. Based on the information at both ends of wire WIRE3, perform a "connect" operation on the target objects C and S1 corresponding to the target object manager. Increase the number of connections of target objects C and S1 by 1, and then merge target object list 3 into target object list 8. After completing the "connect" operation, the target object manager is updated as follows:

[0085] Target object list 4: Target object D (connected times 0).

[0086] Target object list 5: Target object E (connected times 0).

[0087] Target object list 6: Target object F (connected times 0).

[0088] Target object list 7: Target object G (connected times 0).

[0089] Target object list 8: target object S1 (connected 3 times), target object A (connected 1 time), target object B (connected 1 time), target object C (connected 1 time).

[0090] Target object list 9: Target object S2 (connected times 0).

[0091] Target object list 10: Target object S3 (connected times 0).

[0092] 3.4. Based on the information at both ends of wire WIRE4, perform a "connect" operation on the target objects D and S2 corresponding to the target object manager. Increase the number of connections of target objects D and S2 by 1, and then merge target object list 4 into target object list 9. After completing the "connect" operation, the target object manager is updated as follows:

[0093] Target object list 5: Target object E (connected times 0).

[0094] Target object list 6: Target object F (connected times 0).

[0097] Target object list 9: target object S2 (connected times 1), target object D (connected times 1).

[0098] Target object list 10: Target object S3 (connected times 0).

[0099] 3.5. Based on the information at both ends of wire WIRE5, perform a "connect" operation on the target objects E and S2 corresponding to the target object manager. Increase the number of connections of target objects E and S2 by 1, and then merge target object list 5 into target object list 9. After completing the "connect" operation, the target object manager is updated as follows:

[0100] Target object list 6: Target object F (connected times 0).

[0101] Target object list 7: Target object G (connected times 0).

[0102] Target object list 8: target object S1 (connected 3 times), target object A (connected 1 time), target object B (connected 1 time), target object C (connected 1 time).

[0103] Target object list 9: target object S2 (connected times 2), target object D (connected times 1), target object E (connected times 1).

[0104] Target object list 10: Target object S3 (connected times 0).

[0105] 3.6. Based on the information at both ends of wire WIRE6, perform a "connect" operation on the target objects S1 and S2 corresponding to the target object manager. Increase the number of connections of target objects S1 and S2 by 1, and then merge target object list 9 into target object list 8. After completing the "connect" operation, the target object manager is updated as follows:

[0106] Target object list 6: Target object F (connected times 0).

[0107] Target object list 7: Target object G (connected times 0).

[0108] Target object list 8: target object S1 (connected 4 times), target object A (connected 1 time), target object B (connected 1 time), target object C (connected 1 time), target object S2 (connected 3 times), target object D (connected 1 time), target object E (connected 1 time).

[0109] Target object list 10: Target object S3 (connected times 0).

[0110] 3.7. Based on the information at both ends of wire WIRE7, perform a "connect" operation on the target objects F and S3 corresponding to the target object manager. Increase the number of connections of target objects F and S3 by 1, and then merge target object list 6 into target object list 10. After completing the "connect" operation, the target object manager is updated as follows:

[0111] Target object list 7: Target object G (connected times 0).

[0112] Target object list 8: target object S1 (connected 4 times), target object A (connected 1 time), target object B (connected 1 time), target object C (connected 1 time), target object S2 (connected 3 times), target object D (connected 1 time), target object E (connected 1 time).

[0113] Target object list 10: target object S3 (connected times 1), target object F (connected times 1).

[0114] 3.8. Based on the information at both ends of wire WIRE8, perform a "connect" operation on the target objects G and S3 corresponding to the target object manager. Increase the number of connections of target objects G and S3 by 1, and then merge target object list 7 into target object list 10. After completing the "connect" operation, the target object manager is updated as follows:

[0115] Target object list 8: target object S1 (connected 4 times), target object A (connected 1 time), target object B (connected 1 time), target object C (connected 1 time), target object S2 (connected 3 times), target object D (connected 1 time), target object E (connected 1 time).

[0116] Target object list 10: target object S3 (connected times 2), target object F (connected times 1), target object G (connected times 1).

[0117] 3.9. Based on the information at both ends of wire WIRE9, perform a "connect" operation on the target objects S1 and S3 corresponding to the target object manager. Increase the number of connections of target objects S1 and S3 by 1, and then merge target object list 10 into target object list 8. After completing the "connect" operation, the target object manager is updated as follows:

[0118] Target object list 8: target object S1 (connected 5 times), target object A (connected 1 time), target object B (connected 1 time), target object C (connected 1 time), target object S2 (connected 3 times), target object D (connected 1 time), target object E (connected 1 time), target object S3 (connected 3 times), target object F (connected 1 time), target object G (connected 1 time).

[0119] 3.10. Assume that the information of both ends of wire WIRE10 still exists. The two ends of wire WIRE10 are connected as terminal A and wire contact S2. Since target object A and target object S2 already appear in target object list 8 at the same time, it can be determined that wire WIRE10 is a redundant wire.

[0120] The detection algorithm provided by this invention uses the information at both ends of a wire to perform "connection" operations on the target object manager without any order requirements. Changing the order of wire "connection" may result in different sequence numbers in the target object list, but the actual content remains the same, meaning the target object manager's results are exactly the same.

[0121] 4. Detect the wire connection integrity corresponding to the logical connection relationship.

[0122] If all wires have completed the "Connect" operation, the target object manager determines whether the connection is complete. The judgment is based on whether the target object list contains only one target object and whether the target object list has been connected. If the target object manager has completed the connection, the output result is: Connection Complete; otherwise, the output result is: Connection Incomplete.

[0123] The result of judging whether the target object manager and its target object list are connected is as follows:

[0124] Target object list 8: Target object S1 (connected 5 times, connection completed), target object A (connected 1 time, terminal type, connection completed), target object B (connected 1 time, terminal type, connection completed), target object C (connected 1 time, terminal type, connection completed), target object S2 (connected 3 times, connection completed), target object D (connected 1 time, terminal type, connection completed), target object E (connected 1 time, terminal type, connection completed), target object S3 (connected 3 times, connection completed), target object F (connected 1 time, terminal type, connection completed), target object G (connected 1 time, terminal type, connection completed).

[0125] The target object manager has only one target object list, and all of its target objects have been connected. The wire connection integrity judgment result corresponding to this logical connection relationship is: connection complete.

[0126] By using the method of the present invention, only nine cycles of calculation are required to detect the wire connection integrity corresponding to the logical connection relationship. There is no need to repeatedly calculate the wires, thereby achieving rapid calculation of the wire connection integrity of the wiring harness.

[0127] The method for quickly calculating the integrity of a wiring harness provided by the present invention has the following beneficial effects: 1) terminals and wire contacts are added as target objects to a target object manager, and then the integrity of the wire connection is detected through the "connect" operation of the target object manager; 2) based on the information at both ends of the wire, there is no order requirement for the "connect" operation of the target object manager, and the calculation method is simple; 3) the time complexity of the calculation method is O(n), with obvious convergence, and can achieve fast calculation, where n is the number of all wires corresponding to a certain logical connection relationship.

[0128] The present invention has been described exemplarily. Obviously, the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
