[0032] Example 1: Refer to Figure 1 - Figure 7 As shown in the figure: The adapter for the vehicle bus includes a body 1, a dynamic adaptive regulation component 7 is installed on the inner side of the body 1, and a general interface communication end 2 is installed on the surface of the side shell of the body 1;

[0033] The dynamic adaptive regulation component 7 includes a communication circuit board 71, a high-speed oscilloscope chip 72, an intelligent decision-making microcontroller 78, and a spectrum analyzer chip 76. A quantum signal amplifier and a coordination filter 77 are installed on the surface of the communication circuit board 71. The high-speed oscilloscope chip 72 and the spectrum analyzer chip 76 are respectively installed on the side edges of the surface of the communication circuit board 71. A load analysis processor 74 is connected to the side ends of the high-speed oscilloscope chip 72 and the spectrum analyzer chip 76 through line signals. A communication protocol conversion module 73 is installed at the side end of the high-speed oscilloscope chip 72. An analog electromagnetic interference environment unit 75 is installed at the side end of the load analysis processor 74. A fault prediction and diagnosis module 79 is installed at the side end of the surface of the communication circuit board 71. An adaptive communication buffer 791 is connected to the side of the fault prediction and diagnosis module 79 through line signals. The dynamic adaptive regulation component 7 is used to ensure the stable and efficient operation of the in-vehicle bus adapter in a complex and changeable in-vehicle network environment.

[0034] A real-time clock synchronization module 792 is connected to the side end of the adaptive communication buffer 791 through line signals. A data feature automatic focusing unit 793 is signal-connected to the side of the adaptive communication buffer 791. A distributed edge computing node 794 is installed on the side of the communication circuit board 71. The distributed edge computing nodes 794 are distributed at the key nodes of the communication circuit board 71 and the in-vehicle network, and are connected to the intelligent decision-making microcontroller 78, the fault prediction and diagnosis module 79, and the load analysis processor 74 through high-speed communication links. A multi-modal fusion perception module 795 is connected to the side end of the load analysis processor 74 through a high-speed data bus.

[0035] A communication conversion unit is installed on the side of the high-speed oscilloscope chip 72. A grating detector 790 is installed on the side of the communication circuit board 71. A semiconductor heat dissipation structure 796 is installed at the central end of the communication circuit board 71. The side end of the quantum signal amplifier is respectively connected to an intelligent flexible power management module 4 and a standby output control battery 8 through power lines.

[0036] An in-vehicle bus interface end 6 and a jack interface 5 are respectively installed on the bottom surface of the device body 1. A general-purpose port converter 3 is installed at the top end inside the device body 1. A signal equalization module 9 is installed at the bottom of the general-purpose port converter 3.

[0037] An environment adaptive heat dissipation fin array is installed outside the housing of the device body 1. The environment adaptive heat dissipation fin array and the semiconductor heat dissipation structure 796 are connected through heat conducting columns. An adaptive anti-interference antenna array 10 is installed on the surface of the device body 1. The adaptive anti-interference antenna array 10 and the analog electromagnetic interference environment unit 75 form a closed switching connection link through data transmission lines and control lines.

[0038] In a specific solution, when the adapter is connected to the in-vehicle bus system, it first establishes a physical connection with external devices through the in-vehicle bus interface terminal 6 and the jack interface 5. The general port converter 3 starts to work, converting and adapting different types of interface signals to ensure that the adapter can communicate normally with various devices. At the same time, each module in the dynamic adaptive regulation component 7 conducts self-checks. For example, the high-speed oscilloscope chip 72, the spectrum analyzer chip 76, etc. check whether their own working states are normal. The intelligent flexible power management module 4 provides stable power for each component and detects whether the power output is normal. During data transmission, the communication protocol conversion module 73 converts the received different protocol data into a protocol format adapted to the in-vehicle bus and transmits it through the general interface communication terminal 2. The high-speed oscilloscope chip 72 real-time collects communication signals at a high sampling rate, precisely monitors the waveform of the signals, and records parameters such as the rising edge, falling edge, and pulse width of the signals. At the same time, the spectrum analyzer chip 76 conducts spectrum analysis on the signals, calculating spectrum characteristics such as the center frequency, bandwidth, and harmonic content of the signals. These monitoring data will be transmitted to the load analysis processor 74 in the form of a high-speed data stream in real time. After the load analysis processor 74 receives data from the high-speed oscilloscope chip 72 and the spectrum analyzer chip 76, it conducts comprehensive analysis in combination with the environmental information collected by the multi-modal fusion perception module 795. The electromagnetic sensor in the multi-modal fusion perception module 795 real-time monitors the intensity and frequency of surrounding electromagnetic interference, and the temperature sensor measures the working temperature of the adapter. The load analysis processor 74 uses this information to evaluate the load situation of the in-vehicle network, judge whether the current data transmission volume exceeds the network bearing capacity, and whether the adapter is in a normal working state. Once the load analysis processor 74 detects that the in-vehicle network load is too high, such as the data transmission delay exceeding the set threshold, or the signal appears abnormal, such as the amplitude being lower than the normal range, excessive noise, frequency offset, etc., it will immediately transmit this information to the intelligent decision microcontroller 78 through the high-speed communication link, enabling the intelligent decision microcontroller 78 to quickly make decisions and command each module to conduct dynamic regulation according to the preset strategies and algorithms. When it detects that the signal amplitude is too low, it will send an instruction to the quantum signal amplifier to adjust the amplification factor and enhance the signal strength. When the signal noise is too large, the coordination filter 77 will adjust the filtering parameters according to the instruction to filter out the noise and optimize the signal quality. And when the in-vehicle network load is too high, the intelligent decision microcontroller 78 will instruct the communication protocol conversion module 73 to switch to a more efficient data compression and transmission protocol to reduce the data transmission volume and improve the transmission efficiency. The fault prediction and diagnosis module 79 uses big data and artificial intelligence algorithms to conduct in-depth analysis on a large amount of historical data and real-time monitoring data collected, and establishes a fault prediction model to be able to predict potential faults in advance. When it detects that a possible fault may occur, the adaptive communication buffer 791 is quickly started to temporarily store the data to be transmitted to prevent data loss.Meanwhile, the real-time clock synchronization module 792 ensures the time synchronization of data during caching and resuming transmission, guaranteeing the order and accuracy of the data. For example, when there is a brief interruption in the communication link, the adaptive communication buffer 791 stores the data that has not been fully transmitted before the interruption. After the link is restored, the data is re-transmitted orderly according to the time reference of the real-time clock synchronization module 792. Then, when the built-in temperature sensor in the multi-modal fusion perception module 795 detects an increase in the adapter temperature, the intelligent decision-making microcontroller 78 controls the environment-adaptive heat dissipation fin array to adjust the fin angle and spacing, increasing the air convection area and enhancing the air convection heat dissipation effect. At the same time, the semiconductor heat dissipation structure 796 is activated for active heat dissipation to ensure that the adapter operates within a suitable temperature range, avoiding performance degradation or failures caused by overheating. When the analog electromagnetic interference environment unit 75 detects electromagnetic interference, it transmits the interference information to the adaptive anti-interference antenna array 10 through the data transmission line. The adaptive anti-interference antenna array 10 adjusts the direction, gain, and polarization mode of the antenna according to information such as the direction and intensity of the interference source, avoiding the interference source and enhancing the anti-interference ability of the signal, ensuring the stability of communication. This enables intelligent decision-making based on perception data and load conditions, realizing dynamic regulation, improving the adaptability and stability of the adapter in complex environments, enabling it to switch to a more suitable communication protocol mode under the command of the intelligent decision-making microcontroller according to the in-vehicle network load conditions, such as using an efficient data compression and transmission protocol under high load, improving the data transmission efficiency and system adaptability. Furthermore, when the signal fluctuates greatly, the signal multiple and filtering parameters are intelligently adjusted to realize real-time optimization of the signal quality, ensuring the stability and accuracy of the communication signal and guaranteeing the communication stability in complex electromagnetic environments. At the same time, the overall integrated design enables intelligent decision-making and dynamic regulation based on perception data and load conditions, enabling the adapter to quickly adapt to various complex working conditions and changes.

[0039] Embodiment 2: According to Figure 4 - Figure 7 As shown, a detection device for an adapter used in an in-vehicle bus includes an automatic positioning component 11, a detection and regulation component 12, and an adapter adjustment component 13;

[0040] The automatic positioning component 11 is installed at the right end of the adapter adjustment component 13 and is used to drive the adapter to be detected on the surface of the external conveying table for positioning and placement;

[0041] The detection and regulation component 12 is installed at the left end of the adapter adjustment component 13 and is used to comprehensively detect and regulate various performance indicators of the adapter to be detected;

[0042] The adapter adjustment component 13 is installed at the bottom of the detection and regulation component 12 and is used to drive the adapter to be detected to automatically and adaptively fine-tune the detection position.

[0043] The automatic positioning component 11 includes a horizontal linear guide rail 110. A positioning connecting plate 117 is slidably connected to the side end of the horizontal linear guide rail 110. A vertical sliding groove track 118 is installed on the surface of the positioning connecting plate 117. A pneumatic distance adjustment cylinder 112 is installed on the top of the positioning connecting plate 117. A detection integration board 111 is slidably connected to the outside of the vertical sliding groove track 118. A flipping cylinder 114 is installed at the bottom of the positioning connecting plate 117. An adsorption disc 115 is connected to the side end of the flipping cylinder 114 through an electric telescopic rod. A quantum detection and positioning structure 113 is installed at the bottom of the pneumatic distance adjustment cylinder 112. A laser angle detection and guiding device 116 is installed on the side of the horizontal linear guide rail 110.

[0044] In a specific solution, during the detection process, when the external conveyor table transports the adapter to be detected to a specified area near the automated positioning component 11, the horizontal linear guide 110 starts to work. The horizontal linear guide 110 is powered on and started, and the motor inside it drives the lead screw to rotate, thereby driving the positioning connection plate 117 threadedly connected to it to move horizontally along the direction of the guide rail. The positioning connection plate 117 moves to a position close to the adapter on the conveyor table, preparing to grasp the adapter. After the positioning connection plate 117 moves into place, the flipping cylinder 114 operates. The flipping cylinder 114 drives the piston to move through the internal air pressure, driving the rotating shaft connected to the piston to rotate, causing the side end of the flipping cylinder 114 to flip. The electric telescopic rod connected to the side end of the flipping cylinder 114 starts to extend. The motor inside the electric telescopic rod drives the lead screw to extend the telescopic rod, driving the suction cup 115 close to the adapter to be detected. The suction cup 115 uses the principle of vacuum adsorption to firmly adsorb the adapter. Subsequently, the flipping cylinder 114 operates again to flip the adapter to a horizontal state for subsequent precise adjustment and positioning. After the adapter is flipped to the horizontal state, the laser angle detection and guidance device 116 starts to work. The laser angle detection and guidance device 116 emits a laser beam, which irradiates on the surface of the adapter and reflects back. By detecting information such as the angle and time difference of the reflected light, the current angle and position information of the adapter are accurately obtained. These information are transmitted to the external PLC controller in real time. The external PLC controller calculates the parameters that the adapter needs to be adjusted according to the preset standard position parameters. At this time, the pneumatic distance adjustment cylinder 112 starts to work. The pneumatic distance adjustment cylinder 112 adjusts the position of the piston by adjusting the internal air pressure according to the instructions sent by the control system, thereby adjusting the extended length of the cylinder, causing the quantum detection and positioning structure 113 installed at the bottom of the pneumatic distance adjustment cylinder 112 to move up and down. This facilitates the quantum detection and positioning structure 113 to interact with the specific microscopic structure on the surface of the adapter using the principle of quantum entanglement, further accurately determining the position of the adapter and forming coordination with the detection results in the subsequent detection and regulation component 12. In this way, the position of the adapter is finely adjusted to achieve high-precision positioning. At the same time, the detection integration board 111 can slide vertically on the vertical sliding groove 118 to adapt to the detection requirements of adapters of different heights. The detection integration board 111 integrates some sensors and circuits for preliminary detection. During the positioning process of the adapter, preliminary electrical connection and parameter detection of the adapter can be carried out, preparing for subsequent comprehensive detection. This ensures that the adapter is always in the best position during the detection process, greatly improving the accuracy and reliability of the detection results, reducing detection misjudgments caused by positioning errors, and being able to adapt to different detection environments and detection requirements, improving the versatility and adaptability of the detection device, ensuring accurate detection of the adapter under various complex conditions, improving the overall production efficiency, and meeting the requirements for rapid detection of adapters on large-scale production lines.

[0045] Example 3: According to Figure 4 , Figure 5 and Figure 7 As shown, the detection and regulation component 12 includes an installation and bearing frame 121. An image recognition and calibration device 122 is installed on the top of the installation and bearing frame 121. An electrical detection probe 123 is installed in a groove on the surface of the installation and bearing frame 121. An adjustment sliding cylinder 129 is installed at the back end of the electrical detection probe 123. A lifting cylinder 1290 is installed at the bottom of the adjustment sliding cylinder 129. A short-distance sliding guide rail 124 is installed on the surface of the installation and bearing frame 121. A smart spectrum detection module 125 is slidably connected to the top of the short-distance sliding guide rail 124.

[0046] A rod frame 127 is slidably connected inside a vertical groove on the surface of the installation and bearing frame 121. An integrated sensor contact detection point 128 is installed at the side end of the rod frame 127. A lifting cylinder is installed on the back surface of the installation and bearing frame 121. The bottom of the lifting cylinder and the top of the rod frame 127 are firmly connected. Rotating detection robotic arm mounting seats 126 are symmetrically installed on the surface of the installation and bearing frame 121. A force detection robotic arm and a torque detection robotic arm are respectively installed on the surfaces of the rotating detection robotic arm mounting seats 126.

[0047] In a specific solution, after the in-vehicle bus adapter to be detected is accurately placed at the detection position by the automatic positioning component 11, the detection and regulation component 12 starts to enter the preparation stage, enabling the installation and bearing frame 121 to serve as the basic support structure of the entire component, ensuring the stable installation and coordinated operation of each detection component. At this time, the image recognition calibrator 122 is started to quickly scan and identify the appearance, position, and posture of the adapter, facilitating the comparison of the collected image information with the preset standard image to determine whether the adapter is in the correct detection position and posture. When it is found that the adapter has a position deviation or incorrect posture, the image recognition calibrator 122 will feed back the relevant information to the external PLC controller, and the external PLC controller will coordinate the automatic positioning component 11 to further adjust the adapter to ensure that the adapter is in the best detection state. After the position and posture of the adapter are calibrated, the electrical detection probe 123 starts to work, causing the adjustment sliding cylinder 129 to operate. According to the specific position of the adapter and the detection requirements, the electrical detection probe 123 is slid horizontally to the appropriate detection position. Then, the lifting cylinder 1290 is started to move the electrical detection probe 123 downward to make it in close contact with the electrical interface of the adapter. The electrical detection probe 123 detects and collects the basic electrical parameters such as voltage, current, and resistance of the adapter through electrical connection with the adapter, and the detection data is transmitted to the external PLC controller in real time. The external PLC controller compares and analyzes these data with the preset standard electrical parameter range to determine whether the electrical performance of the adapter meets the requirements. During or after the electrical performance detection, the intelligent spectrum detection module 125 starts to work. The intelligent spectrum detection module 125 slides along the short-distance sliding guide rail 124 to an appropriate detection position near the adapter, and uses the built-in spectrum analysis sensor to perform spectrum analysis on the electromagnetic signals generated by the adapter during operation, detecting the spectrum characteristics such as the frequency distribution, bandwidth, and harmonic content of the signals, for evaluating the communication quality and electromagnetic compatibility of the adapter. Then, the intelligent spectrum detection module 125 transmits the detected spectrum data to the external PLC controller, and the external PLC controller determines whether there are problems such as signal interference and frequency offset in the adapter based on these data. Then, the lifting cylinder on the back side of the installation and bearing frame 121 is started to drive the rod frame 127 to move downward along the vertical slot on the surface, so that the integrated sensor contact detection point 128 at the side end of the rod frame 127 contacts the specific detection part of the adapter. The integrated sensor contact detection point 128 integrates various types of sensors, such as temperature sensors, humidity sensors, pressure sensors, etc., and can simultaneously detect multiple physical parameters of the adapter. These parameters reflect the state and performance of the adapter in the actual working environment, and at the same time, the detected data is also transmitted to the external PLC controller, enabling the external PLC controller to comprehensively analyze these data and evaluate the working stability and reliability of the adapter under different physical conditions.After that, the force detection robotic arm and the torque detection robotic arm installed on the rotating detection robotic arm mounting base 126 start to work. The force detection robotic arm detects the magnitude and direction of the force borne by the adapter during installation and use by contacting the mechanical connection part with the adapter. At the same time, the torque detection robotic arm detects the torque of the connection parts such as bolts and nuts of the adapter to ensure that the fastening degree of these connection parts meets the requirements. Then, the force detection robotic arm and the torque detection robotic arm transmit the detected force and torque data to the external PLC controller. The external PLC controller judges whether the mechanical structure of the adapter is firm and whether there is a risk of loosening or damage based on these data, comprehensively understanding the performance and state of the adapter, timely discovering potential problems, greatly improving the accuracy and reliability of the detection, providing a more powerful guarantee for the stable operation of the in-vehicle bus system, comprehensively understanding the performance and state of the adapter, timely discovering potential problems, greatly improving the accuracy and reliability of the detection, providing a more powerful guarantee for the stable operation of the in-vehicle bus system, better adapting to the characteristics and detection requirements of different adapters, improving the detection efficiency and accuracy, reducing manual intervention, and reducing the detection cost.

[0048] Embodiment 4: According to Figure 4 and Figure 7 As shown, the adapter adjustment assembly 13 includes a positioning placement seat 131. The bottom of the positioning placement seat 131 is installed with an adjustment control cylinder 132. The top output end of the adjustment control cylinder 132 is connected with a driving rod 133. The top of the driving rod 133 is fixedly connected with an abutting flexible plate 134. The abutting flexible plate 134 is slidably connected to the sliding groove formed on the surface of the positioning placement seat 131. The top of the positioning placement seat 131 is installed with an impact abutting cylinder 135.

[0049] In a specific solution, when the suction cup 115 in the automatic positioning component 11 transports the in-vehicle bus adapter to be detected to the positioning placement seat 131 in the adapter adjustment component 13, at this time, the entire adapter adjustment component 13 is in the initial state, the adjustment control cylinder 132 and the impact contact cylinder 135 are not actuated, and the contact flexible plate 134 is located at the initial position of the sliding groove on the surface of the positioning placement seat 131. After the detection and regulation component 12 conducts a preliminary detection on the adapter, when it is found that the position of the adapter has a certain deviation and cannot meet the accuracy requirements of some detection items, at this time, the adapter adjustment component 13 will start to perform a preliminary position fine-tuning. The adjustment control cylinder 132 starts to act after receiving an instruction issued by an external PLC controller. The top output end of it pushes the driving rod 133 to move. Since the top of the driving rod 133 is fixedly connected to the contact flexible plate 134, the contact flexible plate 134 will slide along the sliding groove on the surface of the positioning placement seat 131. During the sliding process, the contact flexible plate 134 will contact the side surface of the adapter and push the adapter to move slightly in the horizontal direction in a flexible manner, thereby realizing the position fine-tuning of the adapter on the positioning placement seat 131 and making it closer to the ideal detection position. After the preliminary position fine-tuning is completed, in order to ensure the stability of the adapter during the subsequent detection process, the impact contact cylinder 135 starts to work. The piston rod of the impact contact cylinder 135 extends, applying a certain impact force to the adapter to further fix the adapter on the positioning placement seat 131.
