[0050] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0051] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0052] The main solution of the embodiment of the present application is: in response to a received arrival signal, identifying the position information of the vehicle charging port cover by a multi-axis robot, wherein the arrival signal is generated when the vehicle arrives at the test station; according to the position information of the charging port cover, controlling the multi-axis robot to open the charging port cover and insert the plug of the discharge gun into the charging port; when it is detected that the plug of the discharge gun is successfully connected to the charging port, performing a discharge function test by the discharge gun to obtain discharge parameters; and determining the discharge function test result according to the discharge parameters.

[0053] As new energy vehicles become more and more popular, their functions are becoming more and more diverse and intelligent. The discharge function of the vehicle is one of the highlights. At present, most OEMs use the discharge gun's built-in socket and the attached bulb to light up and the load to determine whether the vehicle's discharge function is normal when checking its function. This method requires manual insertion of the discharge gun into the vehicle's discharge port, and the result is manually identified and judged. It is impossible to accurately detect the relevant parameters of the discharge. There are not only certain limitations in operation, but also certain safety risks. It can be seen that the current discharge function test efficiency and accuracy are poor, and there are safety risks. Therefore, how to effectively improve the efficiency and accuracy of vehicle discharge function detection is a problem that needs to be solved urgently.

[0054] The present application generates an arrival signal when the vehicle arrives at the test station, automatically triggers the multi-axis robot to identify the position information of the vehicle charging port cover, and controls the multi-axis robot to insert the plug of the discharge gun into the charging port for a discharge function test, and quickly and accurately determines the discharge function test result based on the discharge parameters obtained from the test, thereby overcoming the technical defects of the current discharge function test, such as poor efficiency and accuracy, and the presence of safety risks, and can effectively improve the efficiency and accuracy of vehicle discharge function testing.

[0055] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vehicle discharge function detection device, etc. The following takes the vehicle discharge function detection device as an example to illustrate this embodiment and the following embodiments.

[0056] Based on this, the embodiment of the present application provides a vehicle discharge function detection method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle discharge function detection method of the present application.

[0057] In this embodiment, the vehicle discharge function detection method includes steps S10 to S40:

[0058] Step S10, in response to the received arrival signal, identifying the position information of the vehicle charging port cover by a multi-axis robot, wherein the arrival signal is generated when the vehicle arrives at the test station.

[0059] It should be noted that the arrival signal can be generated by a sensor, a photoelectric switch, a ground sensor coil, etc. when the vehicle arrives at the test station. The arrival signal is transmitted to the host computer, and the host computer sends a command to the multi-axis robot to identify the vehicle charging port cover.

[0060] It is understood that the multi-axis robot is a highly flexible and precise automated device that can perform complex tasks such as identifying the position information of the vehicle charging port cover and performing discharge function detection. In this embodiment, the multi-axis robot is equipped with a high-definition camera, a discharge gun plug, a finger-like rubber contact, a robot moving guide rail, and a robot moving bottom.

[0061] In the specific implementation, after the vehicle arrives at the inspection station, the initial position of the vehicle is located through the V-shaped rolling groove on the ground. The ground-mounted reflective switches installed on both sides of the front and rear wheels of the vehicle are used to determine that the vehicle is in place, generate arrival information, and transmit the arrival signal to the host computer.

[0062] In this embodiment, the vehicle discharge function detection equipment is arranged with a host computer control and detection system and a discharge function test system. The host computer control and detection system includes a control cabinet, an industrial computer, a PLC, digital input and output ports, analog signal input and output ports, programmable device software, a safety relay, a limit switch, etc., which can realize the mechanical motion control and position monitoring of the discharge function test system to determine whether the mechanical execution is in place, and compare / store the test results. If an interface is opened with other production management systems, the test results can also be uploaded to the production management system, etc. The discharge function test system includes a control circuit (including a controller circuit and a safety circuit), an actuator, a position and state monitoring mechanism and a test circuit, wherein the controller circuit and the safety circuit are used to execute actions of the action controller relay, the safety relay, the circuit breaker and the like according to the PLC and other instructions issued by the host computer, so as to realize the motion control of the mechanical structure; the actuator is a multi-axis robot, which is composed of a robot base, a servo motor, a high-definition camera, a quasi-finger rubber contact, a discharge gun and other components, and can realize various displacement, rotation and other actions to realize automatic positioning and stepping and other actions; the position and state monitoring mechanism is composed of various position sensors, height sensors, pressure sensors, beam switches, magnetic switches and the like, which realizes the position monitoring and state monitoring of the actuator to ensure the normal operation of the system; the test circuit is composed of various voltmeters, ammeters, electric energy meters, adjustable rheostats, discharge resistors and the like, which realizes the measurement of discharge voltage, discharge current, discharge frequency and discharge power.

[0063] like Figure 2 As shown, Figure 2 The figure is a communication relationship diagram of a vehicle discharge function detection device, wherein the vehicle discharge function detection device includes a host computer control and detection system and a discharge function test system, the host computer control and detection system and the discharge function test system are communicatively connected, the discharge function test system includes a control circuit (including a controller circuit and a safety circuit), an actuator, a position and state monitoring mechanism and a test circuit, the host computer control and detection system, the control circuit, the actuator, the test circuit and the vehicle to be tested are communicatively connected in sequence, and the control circuit, the actuator and the test circuit are all communicatively connected with the position and state monitoring mechanism.

[0064] like Figure 3 As shown, Figure 3 It is a structural diagram of a vehicle discharge function detection device, which includes a host computer control and detection system 1 and a discharge function test system. The discharge function test system includes a multi-axis robot 2, wherein the multi-axis robot 2 includes a high-definition camera 3, a discharge gun plug 4, a simulated rubber contact 5, a robot moving guide rail 6 and a robot moving base 7. The multi-axis robot 2 is used to perform a discharge function test on a vehicle to be tested 8.

[0065] In a feasible implementation, step S10 may include: in response to a received arrival signal, controlling the multi-axis robot to move to the target position of the vehicle; when detecting that the multi-axis robot reaches the target position of the vehicle, controlling the robotic arm of the multi-axis robot to identify and locate the vehicle charging port cover to obtain the position information of the vehicle charging port cover.

[0066] It should be noted that the target position of the vehicle refers to the location of the vehicle charging port cover. After the multi-axis robot moves to the target position, the robot scans the vehicle charging port cover through the visual recognition system (i.e., high-definition camera) at the end of the robot arm, takes an image of the charging port cover, and uses image processing technology to identify and locate it, thereby obtaining accurate position information.

[0067] It is understandable that the multi-axis robot's mechanical arm is highly flexible and accurate, and can adapt to the position of the charging port cover of various models. During the recognition and positioning process, the image captured by the high-definition camera is transmitted to the industrial computer in the control cabinet. The industrial computer analyzes the image through the image processing algorithm, identifies the characteristic points of the charging port cover, and calculates its precise position. The industrial computer converts this position information into motion instructions for the multi-axis robot's mechanical arm, thereby achieving precise positioning of the charging port cover.

[0068] In a feasible embodiment, in response to the received in-position signal, controlling the multi-axis robot to move to the target position of the vehicle includes: identifying the frame number information of the vehicle in response to the received in-position signal; determining the vehicle model according to the frame number information; determining the target position of the vehicle according to the vehicle model, and controlling the multi-axis robot to move to the target position of the vehicle.

[0069] It should be noted that the frame number information is the unique identifier of the vehicle. By identifying the frame number information, detailed information of the vehicle can be obtained, including model, production year, configuration, etc. This information is crucial to determine the target location of the vehicle, because the location of the charging port cover may be different for different models.

[0070] In the specific implementation, the multi-axis robot first scans the vehicle through its visual recognition system to obtain the frame number information. The frame number information is transmitted to the host computer control and detection system. The host computer queries the location of the vehicle charging port cover of the corresponding model through the built-in database, and sends control instructions to the robot through the PLC. The robot automatically moves to the corresponding position of the vehicle charging port cover according to the preset program. The database stores detailed parameters of various models, including the specific location information of the charging port cover. In this way, the multi-axis robot can automatically adjust its movement path and posture according to different models to ensure that it reaches the corresponding position of the vehicle charging port cover accurately.

[0071] Step S20, controlling the multi-axis robot to open the charging port cover and inserting the plug of the discharge gun into the charging port according to the position information of the charging port cover.

[0072] It should be noted that the host computer control and detection system generates corresponding action instructions based on the position information of the charging port cover, and controls the multi-axis robot's mechanical arm to open the charging port cover through control instructions. The end of the mechanical arm is equipped with quasi-finger rubber contacts, which have a certain elasticity and friction, and can stably grasp and open the charging port cover. After the charging port cover is successfully opened, the multi-axis robot aligns the discharge gun plug with the charging port, and uses its high-precision positioning system to ensure that the plug is accurately inserted into the charging port. The entire process is monitored in real time by the industrial computer to ensure the safety and accuracy of the operation.

[0073] In a feasible implementation, step S20 may include: controlling the robotic arm of the multi-axis robot to move to the location of the charging port cover according to the position information of the charging port cover and controlling the simulated rubber contact at the end of the robotic arm to press the charging port cover to open the charging port cover; when the charging port cover is opened, controlling the multi-axis robot to insert the plug of the discharge gun into the charging port.

[0074] It should be noted that the simulated rubber contact at the end of the robotic arm has good adaptability and stability, and can cope with the differences in material and shape of the charging port covers of different models. When pressing the charging port cover, the contact will automatically adjust the force according to the actual contact situation to avoid damage to the charging port cover. At the same time, the control system of the robotic arm will monitor the contact force between the contact and the charging port cover in real time to ensure that it does not exceed the set safety range during the opening process.

[0075] It is understandable that if the vehicle has an electric charging port cover, there is no need for the robot to press it open, and the charging port cover is opened by the vehicle end.

[0076] It is worth mentioning that after the charging port cover is opened, the multi-axis robot will quickly adjust the position of its robotic arm to align the plug of the discharge gun with the charging port. To ensure that the plug can be inserted smoothly, the end of the robotic arm is equipped with a high-precision visual recognition system, which can capture the image of the charging port in real time and analyze the shape, size and position of the charging port through image processing algorithms. Based on this data, the robotic arm can automatically adjust its posture and direction to ensure that the discharge gun plug is perfectly connected to the charging port.

[0077] It is worth mentioning that in order to further improve the accuracy and safety of the operation, the multi-axis robot is also equipped with a force sensor to monitor the contact force between the end of the robot arm and the charging port in real time. During the plug insertion process, the force sensor can ensure that the plug is inserted into the charging port with appropriate force to avoid the plug being unable to be firmly connected to the charging port due to excessive or insufficient force.

[0078] Step S30, when it is detected that the plug of the discharge gun is successfully connected to the charging port, a discharge function test is performed by the discharge gun to obtain a discharge parameter.

[0079] It should be noted that after the charging port cover is opened and the discharge gun plug is inserted, the multi-axis robot will use sensors to detect whether the plug is firmly connected to the charging port. If the connection is unstable or unsuccessful, the robot will automatically adjust the position of the plug until the connection is correct. The entire process is monitored in real time by the industrial computer, and the operation data is recorded for subsequent analysis and optimization.

[0080] It is understood that the discharge function test refers to discharging the battery through a discharge gun to verify the performance and health of the battery. The discharge parameters include key indicators such as discharge current and voltage, which are not specifically limited in this embodiment. These parameters can reflect whether the battery works normally during the discharge process.

[0081] In a feasible implementation, step S30 may include: when it is detected that the plug of the discharge gun is successfully connected to the charging port, controlling the discharge gun to perform simulated discharge; collecting the discharge current, discharge voltage, discharge power and discharge frequency during the simulated discharge process; and obtaining discharge parameters according to the discharge current, the discharge voltage, the discharge power and the discharge frequency.

[0082] It should be noted that during the simulated discharge process, the discharge gun will gradually increase the discharge current according to the preset discharge program, while monitoring the voltage changes of the battery in real time. In this way, the performance of the battery in different discharge stages can be ensured. If the battery is abnormal during the discharge process, such as the voltage drops too fast or the current is unstable, the system will immediately stop discharging and issue an alarm to prompt maintenance personnel to check.

[0083] It is understandable that in this embodiment, the discharge parameters include discharge current, discharge voltage, discharge power and discharge frequency. The magnitude of the discharge current directly affects the discharge time and discharge efficiency of the battery. For example, a discharge current that is too large may cause the battery to overheat and affect the battery life; while a discharge current that is too small may cause the battery to fail to meet actual usage requirements. The discharge voltage reflects the voltage stability of the battery during the discharge process. During the discharge process, the voltage of the battery will gradually decrease, but ideally it should be kept within a relatively stable range. If the discharge voltage drops too fast or fluctuates abnormally, it may indicate that the battery has internal short circuits or aging problems. Discharge power refers to the energy released by the battery per unit time. It is closely related to the discharge current and discharge voltage. The magnitude of the discharge power directly affects the discharge efficiency and application range of the battery. The discharge frequency refers to the frequency of the number of times the battery is discharged per unit time, which reflects the discharge rate of the battery.

[0084] In a specific implementation, after completing the discharge function test, the multi-axis robot will automatically disconnect the discharge gun from the charging port and move the discharge gun to a standby position.

[0085] Step S40: determining a discharge function detection result according to the discharge parameter.

[0086] It should be noted that the discharge function test results include normal discharge function and abnormal discharge function. Normal discharge function means that all parameters of the battery are within the predetermined range during the discharge process, the battery performance is good, and there is no obvious abnormality. Abnormal discharge function indicates that the battery has unexpected performance during the discharge process, such as too fast voltage drop, unstable current, abnormal discharge power or abnormal discharge frequency, which may indicate potential problems with the battery and require further inspection and repair.

[0087] It is understandable that the industrial control machine will conduct a comprehensive analysis based on the discharge parameters, and automatically determine the discharge function test results by comparing them with the preset normal parameter range.

[0088] In the specific implementation, the upper computer compares the discharge parameters with the preset values ​​to determine whether the discharge function is qualified. If qualified, the green light will light up and a test result report will be printed. If unqualified, the red light will light up and a failure report will be printed.

[0089] The present embodiment provides a vehicle discharge function detection method. The present embodiment first responds to a received in-position signal and identifies the position information of the vehicle charging port cover by a multi-axis robot, wherein the in-position signal is generated when the vehicle arrives at a test station; according to the position information of the charging port cover, the multi-axis robot is controlled to open the charging port cover and insert the plug of the discharge gun into the charging port; when it is detected that the plug of the discharge gun is successfully connected to the charging port, a discharge function detection is performed by the discharge gun to obtain a discharge parameter; and a discharge function detection result is determined according to the discharge parameter, which can effectively improve the efficiency and accuracy of the vehicle discharge function detection.

[0090] In summary, this embodiment generates an arrival signal when the vehicle arrives at the test station, automatically triggers the multi-axis robot to identify the position information of the vehicle charging port cover, and controls the multi-axis robot to insert the plug of the discharge gun into the charging port for discharge function detection, and quickly and accurately determines the discharge function test result according to the discharge parameters obtained by the test, thereby overcoming the technical defects of the current discharge function test, such as poor efficiency and accuracy, and the existence of safety risks, and can effectively improve the efficiency and accuracy of vehicle discharge function detection.

[0091] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 4, the step S40 further includes steps S401-S402:

[0092] Step S401 : comparing the discharge current, discharge voltage, discharge power and discharge frequency in the discharge parameters with corresponding parameter thresholds respectively to obtain a comparison result.

[0093] It should be noted that the parameter thresholds corresponding to the discharge current, discharge voltage, discharge power and discharge frequency are respectively the preset current threshold, the preset voltage threshold, the preset power threshold and the preset frequency threshold. These thresholds are set according to the normal working range of the vehicle discharge function to ensure the accuracy of the detection results.

[0094] It is understandable that comparing the discharge parameters with the parameter thresholds can effectively determine whether the vehicle discharge function is normal. If all parameters are within the preset threshold range, it can be determined that the discharge function is normal; conversely, if any parameter exceeds the threshold range, it indicates that there is a problem with the discharge function.

[0095] Step S402: determining a discharge function detection result according to the comparison result.

[0096] It should be noted that when determining the discharge function test result, the comparison results of various parameters will be comprehensively considered. If all parameters are within the preset threshold range, the system will output the test result of "normal discharge function"; if any parameter exceeds the threshold range, the system will output the test result of "abnormal discharge function".

[0097] It is understandable that in order to further improve the accuracy and reliability of detection, a tolerance range can be set. For example, if a parameter exceeds the threshold range but only by a small margin, the system can regard it as a fluctuation within the normal range, thereby avoiding misjudgment. However, if the margin exceeds by a large margin, the system will immediately determine it as abnormal to ensure the safety of the vehicle.

[0098] In a feasible implementation, step S402 may include: when the comparison result is that the discharge current, the discharge voltage, the discharge power and the discharge frequency all reach the corresponding parameter thresholds, determining that the discharge function detection result is a normal discharge function; when the comparison result is that at least one of the discharge current, the discharge voltage, the discharge power and the discharge frequency does not reach the corresponding parameter threshold, determining that the discharge function detection result is an abnormal discharge function.

[0099] It should be noted that if the discharge current, discharge voltage, discharge power and discharge frequency are all within the corresponding parameter threshold range, the discharge function is determined to be normal; conversely, if any parameter exceeds its corresponding threshold range, the discharge function is determined to be abnormal.

[0100] It is understandable that the discharge function detection can also make a comprehensive judgment based on the real-time operating status of the vehicle and environmental factors. For example, in high or low temperature environments, the performance of the battery may be affected, causing fluctuations in the discharge parameters. In this case, the system can adjust the parameter threshold to adapt to different environmental conditions, thereby avoiding misjudgment due to environmental factors.

[0101] In this embodiment, by comparing the discharge parameters with the corresponding parameter thresholds respectively, the discharge function detection result is quickly and accurately determined according to the comparison result, thereby achieving rapid and accurate detection of the vehicle discharge function.

[0102] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the vehicle discharge function detection method of the present application. More simple transformations based on this technical concept are all within the protection scope of the present application.

[0103] This application also provides a vehicle discharge function detection device, please refer to Figure 5 , the vehicle discharge function detection device comprises:

[0104] The identification module 10 is used to identify the position information of the vehicle charging port cover through a multi-axis robot in response to a received arrival signal, wherein the arrival signal is generated when the vehicle arrives at the test station.

[0105] The control module 20 is used to control the multi-axis robot to open the charging port cover and insert the plug of the discharge gun into the charging port according to the position information of the charging port cover.

[0106] The detection module 30 is used to perform a discharge function test through the discharge gun to obtain discharge parameters when it is detected that the plug of the discharge gun is successfully connected to the charging port.
