Description

Technical Field

[0001] This invention relates to a detection device and method, and more particularly to a general-purpose automotive module circuit fault setting and detection device and method, belonging to the technical field of automotive teaching and training equipment. Background Technology

[0002] With the widespread application of electronic technology in the automotive field, the number of modules used in automobiles is increasing day by day.

[0003] In the teaching process of automotive majors in colleges and universities, especially vocational colleges, practical teaching is needed with the help of teaching and training equipment in order to enable students to better master the skills of fault diagnosis and repair of automotive modules.

[0004] Currently, traditional training equipment is usually based on real vehicles as the platform, with fault setting boxes and connection adapters configured for each module. However, when there are many vehicle modules and many module pins, the entire fault setting and detection system becomes very complex and the cost is high. This not only increases the teaching cost of schools, but may also cause difficulties for students during operation due to the complexity of the equipment, thus affecting the teaching effect.

[0005] Therefore, it is urgent to improve the fault settings of general automotive module circuits in order to solve the above-mentioned technical problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a universal automotive module circuit fault setting and detection device and method, which only requires a detection board, a detection guide board with the same number of modules, and a universal fault setting box to realize the structure of the fault setting and detection system.

[0007] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: A universal automotive module circuit fault setting and detection device, comprising: The detection board adopts a dual-core heterogeneous architecture of FPGA and ARM, supports microsecond-level signal synchronization and multi-protocol real-time communication, and is equipped with multiple metal detection terminals. A detection guide plate with the same number of modules as the vehicle, wherein the position, size, and shape of the holes in the detection guide plate are consistent with those in the detection plate; and A fault setting box having a sufficient number of switches, the front end of which is used to connect the lead wire of the module wiring harness connector, and the rear end of which is used to connect the lead wire of the empty shell of the pin module and the metal detection terminal of the detection board. The fault setting box is electrically connected to multiple wire harness connectors via wires, and each wire harness connector has a module shell with pins.

[0008] Furthermore, the metal detection terminals on the detection board are arranged neatly, and each terminal corresponds to a specific pin position, which facilitates accurate connection and detection. The number of metal detection terminals on the detection board is determined according to the maximum number of pins that may be encountered in the actual module. When processing a module with 90 pins, the detection board is equipped with 90 metal detection terminals.

[0009] Furthermore, the lead wire of the module wiring harness connector is connected to the front end of the switch in the fault setting box, and the lead wire of the empty shell of the pin module is connected to the rear end of the switch in the fault setting box. The number of switches in the fault setting box is determined based on the maximum number of pins that may actually be encountered. For a vehicle with 90 pin modules, a universal fault setting box with 90 switches is set up.

[0010] Furthermore, when performing fault detection on a specific module, the detection guide board is used in conjunction with the detection board. During fault detection, the corresponding detection guide board covers the detection board to form a detection loop, ensuring the accuracy and convenience of the detection operation.

[0011] Furthermore, the switch of the fault setting box is an electronic switch or a mechanical switch, which can reliably and stably realize the opening and closing operations to accurately simulate different fault conditions.

[0012] Furthermore, the pins of the hollow shell of the pin module are specially treated to ensure good conductivity and a stable connection, thereby ensuring the quality of signal transmission during fault setting and detection.

[0013] Furthermore, the module harness connector has a standardized interface, enabling quick and accurate connection with different types of standard-compliant module pins.

[0014] This invention also provides a method for detecting fault settings in a universal automotive module circuit, which includes the following steps: S1. Accurately connect the corresponding module harness connector to the pins of the original module to ensure a secure connection and normal signal transmission; S2. Connect the empty module shell with pins to the wire harness connector of the original module to form a complete analog module circuit structure. S3. Based on teaching or testing needs, selectively disconnect one or more switches in the fault setting box to simulate the required module circuit fault state. S4. Accurately cover the test board with the corresponding test guide plate, and conduct a comprehensive and detailed test using the metal test terminals on the test board and related test equipment to determine the cause of the fault.

[0015] Furthermore, when connecting the module harness connector and the pinned module housing, use professional connection tools to ensure the stability and reliability of the connection and avoid problems such as poor contact.

[0016] Furthermore, the relevant testing equipment includes at least one of a multimeter and an oscilloscope. When setting up faults, the switches to be disconnected are selected in a targeted manner according to the functional characteristics of different modules and common fault types, so as to simulate fault conditions that are closer to real-world scenarios and improve teaching effectiveness and the practicality of testing.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Compared with the traditional method of configuring a separate fault setting box and connection adapter for each module, this device only requires a detection board and a detection guide board with the same number of modules, as well as a universal fault setting box, which greatly simplifies the structure of the fault setting and detection system and significantly reduces teaching costs.

[0018] 2. From connecting the module wiring harness connector to setting faults and then performing tests, the steps are clear and concise, with strong operability. Operators can follow these steps to complete the fault setting and testing work, improving the standardization and efficiency of the work. This method can be used for fault setting and testing for different vehicle models and different numbers of modules. Regardless of the number of pins of the module, only the number of switches on the test board and fault setting box needs to be set according to the maximum number of pins. Other modules with fewer pins can use only some pins and switches, which has strong adaptability and versatility. Attached Figure Description

This can be deduced by analogy.

Detailed Implementation

[0020] The technical solution of the present invention will be further described in a non-limiting manner below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-4 As shown, the universal automotive module circuit fault setting and detection device and method provided in this embodiment includes: The detection board adopts a dual-core heterogeneous architecture of FPGA and ARM, supports microsecond-level signal synchronization and multi-protocol real-time communication, and has multiple metal detection terminals, which greatly improves the performance and processing capabilities of the detection board. The number of test guide plates is the same as that of the automotive modules. The position, size, and shape of the holes on the test guide plates are consistent with those on the test plates, ensuring precise adaptation between the two. This allows for accurate guidance during the testing process, avoiding testing errors caused by adaptation issues. When performing fault testing on a specific module, the test guide plates are used in conjunction with the test plates. During fault testing, the corresponding test guide plate covers the test plate, forming a test loop. This ensures the accuracy and convenience of the testing operation, allowing operators to clearly follow the steps and improving the standardization and efficiency of the testing work. Furthermore: The fault setting box has a sufficient number of switches. The front end of the switches is used to connect the lead wires of the module wiring harness connector, and the rear end of the switches is used to connect the lead wires of the module shell with pins and the metal detection terminals of the detection board. This clearly constructs the circuit connection framework for the entire fault setting and detection. Multiple wiring harness connectors are electrically connected to the fault setting box via wires. The wiring harness connectors are equipped with module shells with pins. This design facilitates the connection between the module and the fault setting box and improves the overall integrity and operability of the device.

[0022] Compared to traditional methods that require a separate fault setting box and connection adapter for each module, this device reduces equipment complexity. It only requires a detection board, a detection guide board with the same number of modules, and a universal fault setting box, which greatly simplifies the structure of the fault setting and detection system.

[0023] In a further technical solution of this embodiment, such as Figure 1 As shown, the metal detection terminals on the detection board are neatly arranged, and each terminal corresponds to a specific pin position, facilitating accurate connection and testing. The number of metal detection terminals on the detection board is determined based on the maximum number of pins that may be encountered in the actual module. When processing a module with 90 pins, the detection board is equipped with 90 metal detection terminals. The neat arrangement of the metal detection terminals and the fact that each terminal corresponds to a specific pin position makes it easy for operators to quickly and accurately find the corresponding terminals during connection and testing, reducing operational errors and improving testing efficiency. Taking the setting of 90 metal detection terminals when processing a 90-pin module as an example, the setting of the number of terminals has a clear basis and standard, which not only meets the actual testing needs but also avoids the waste of resources.

[0024] The lead wires of the module wiring harness connector are connected to the front end of the switch in the fault setting box, and the lead wires of the empty shell of the pin module are connected to the rear end of the switch in the fault setting box. The number of switches in the fault setting box is determined according to the maximum number of pin modules that may actually be encountered. For the case of 90 pin modules in the whole vehicle, a universal fault setting box with 90 switches is set up. The number of switches in the fault setting box is determined according to the maximum number of pin modules that may actually be encountered. This provides a clear standard for setting the number of switches in the fault setting box, which helps to unify the specifications of the device and reduce costs. In addition, the fault setting box uses either electronic or mechanical switches, which can reliably and stably perform open and close operations to accurately simulate different fault conditions. Both types of switches are common and reliable, providing multiple options for fault setting and enhancing the applicability and flexibility of the device.

[0025] In a further technical solution of this embodiment, such as Figure 1 As shown, the pins of the empty shell of the pin-mounted module are specially treated to ensure good conductivity and a stable connection, ensuring signal transmission quality during fault setting and detection. The module harness connector has a standardized interface, enabling quick and accurate connection with different types of standard-compliant module pins.

[0026] like Figure 4 As shown, the detection method for general automotive module circuit fault settings provided in this embodiment includes the following steps: S1. Accurately connect the corresponding module harness connector to the pins of the original module to ensure a secure connection and normal signal transmission; S2. Connect the empty module shell with pins to the wire harness connector of the original module to form a complete analog module circuit structure. S3. Based on teaching or testing needs, selectively disconnect one or more switches in the fault setting box to simulate the required module circuit fault state. S4. Accurately cover the test board with the corresponding test guide plate, and conduct a comprehensive and detailed test through the metal test terminals on the test board and related test equipment to determine the cause of the fault. From connecting the module harness connector to setting the fault and then to conducting the test, the steps are clear and specific, and have strong operability. Operators can follow these steps to complete the fault setting and test work, which improves the standardization and efficiency of the work. This method can set and detect faults for different vehicle models and different numbers of modules. Regardless of the number of pins in a module, the number of switches on the detection board and fault setting box only needs to be set according to the maximum number of pins. Other modules with fewer pins can use only some pins and switches, which has strong adaptability and versatility.

[0027] In this embodiment, when connecting the module harness connector and the module shell with pins, professional connection tools are used to ensure the stability and reliability of the connection and avoid problems such as poor contact. The relevant testing equipment includes at least one of a multimeter and an oscilloscope. When setting faults, the switches to be disconnected are selected in a targeted manner according to the functional characteristics of different modules and common fault types to simulate fault conditions that are closer to real-world scenarios, thereby improving the teaching effect and the practicality of testing. This requirement makes the fault settings more in line with the actual situation and helps to better cultivate the operators' practical skills and problem-solving abilities.

[0028] like Figure 2 As shown, the principle of the universal automotive module circuit fault setting and detection device and method provided in this embodiment is as follows: The working principle of this device is explained using three modules (Module A, Module B, and Module C) as an example; the same principle applies to more modules.

[0030] Module B Fault Setting and Detection: The module B wiring harness connector only requires the wiring corresponding to pins 1-8; Connect the module B harness connector to the pins of the original module B; Connect the pinned module B shell to the original module B wiring harness connector. Only pins 1-8 are needed for the pinned module B shell. In the fault setting box, disconnect one or more switches from 1 to 8 as needed to set the fault; Cover the test board with the module B test guide board and perform the relevant tests.

[0031] Module C Fault Setting and Detection: The module C wiring harness connector only requires the wiring corresponding to pins 1-6; Connect the module C harness connector to the pins of the original module C; Connect the pinned module C shell to the original module C wiring harness connector. Only pins 1-6 are needed for the pinned module C shell.
