Description

Technical Field

[0001] The present invention relates to the technical field of automobile charging, and in particular to a control method, system and terminal of a megawatt-class ultra-fast charging system. Background Art

[0002] The megawatt-class ultra-fast charging system is an advanced charging technology with the characteristics of high power, high voltage, and large current.

[0003] The traditional charging method has low power and cannot meet the fast charging needs of these vehicles, so the megawatt-class ultra-fast charging system came into being. The megawatt-class ultra-fast charging system can provide higher power than the existing charging standards, allowing vehicles to obtain a large amount of electricity in a shorter time. The megawatt-class ultra-fast charging system includes a megawatt-class ultra-fast charging pile and a control system that stores megawatt-class ultra-fast charging technology, thereby increasing the range of electric vehicles while reducing users' concerns about the range of electric vehicles. The megawatt-class ultra-fast charging pile includes a charging pile body, a charging connector, a cable device for connecting the charging connector to the charging pile body, and a gripping part integrated with the charging connector. When the user's vehicle needs to be charged, the user needs to drive to the location of the megawatt-class ultra-fast charging pile and manually drive the gripping part to insert the charging connector into the vehicle's interface for charging.

[0004] When a megawatt-class ultra-fast charging pile is only equipped with a single charging connector, the single charging connector can only be used to charge some models of vehicles. Vehicles of other models can only find a charging pile corresponding to a connector that matches the vehicle interface. As a result, megawatt-class ultra-fast charging piles equipped with a single charging connector are not convenient for widespread use and need to be improved. Summary of the invention

[0005] In order to facilitate the widespread use of a megawatt-class ultra-fast charging system, the present invention provides a control method, system and terminal for a megawatt-class ultra-fast charging system.

[0026] According to the vibration power and the abnormal position, the vibration device preset in the cleaning device is controlled to vibrate to clean the dust.

[0027] By adopting the above technical solution, the color of the connector is understood to obtain the connector color parameters, and the color deviation parameters are compared with the reference deviation parameters. Based on the comparison result, the user is prompted to insert the charging connector into the cleaning device, and then the vibration device is controlled by the vibration power and abnormal position to clean the dust on the charging connector, so that it is not easy for the megawatt ultra-fast charging pile to have charging abnormalities.

[0028] Optionally, the method of controlling a vibration device preset in the cleaning device to vibrate to clean dust includes:

[0029] After the vibration device vibrates, the preset clamping device is controlled to clamp the charging device to a preset reset position, and determine whether there is a color deviation parameter in the connector image information;

[0030] If there is no color deviation parameter in the joint image information, the preset prompt information continues to be output;

[0031] If there is a color deviation parameter in the connector image information, obtain the humidity detection value on the charging connector;

[0032] When the humidity detection value is greater than a preset reference humidity value, the humidity distribution position is determined according to the humidity detection value and the joint image information;

[0036] By adopting the above technical solution, the erasing path is obtained by understanding the water droplets and dust on the charging connector, and a new erasing path is obtained through the moisture adsorption position and the abnormal position. Then, the erasing device is controlled to operate with the new erasing path, so that the erasing device adsorbed with moisture can erase the dust, further improving the efficiency of dust erasing.

[0037] Optionally, the method further includes clamping the charging device to a preset reset position:

[0041] Determine whether the surrounding wind direction information is consistent with the preset reference wind direction information;

[0042] If the surrounding wind direction information is inconsistent with the reference wind direction information, continue to obtain the surrounding environment detection information;

The shielding position is obtained according to the comparison result, and the shielding device is controlled to shield at the shielding position, so that it is not easy for rainwater to drip onto the charging connector to cause charging abnormalities.

[0052] Match the connector blowing power from the preset blowing database according to the dust coverage of the interface;

[0053] Obtain actual image information on the charging connector;

[0054] When complete interface features appear in the actual image information, the actual distance value between the charging connector and the vehicle is obtained;

[0055] When the actual distance value is less than the preset reference distance value, the blowing device preset on the charging device is controlled to blow air based on the connector blowing power until the charging connector outputs the preset charging trigger information.

[0056] By adopting the above technical solution, the interface on the vehicle is understood to know the interface color parameters and the reference interface color parameters, and the interface color deviation parameters are obtained through the interface color information and the interface reference color. Then, the connector blowing power is obtained through the interface color deviation parameters and the operation of the blowing device is controlled, so that the dust in the vehicle interface can be cleaned, and it is not easy for the megawatt ultra-fast charging pile to have charging abnormalities.

[0057] Optionally, the method further includes controlling the blowing device to blow air:

[0058] When the charging connector outputs a preset charging trigger information, the blowing device is stopped and a temperature detection value in the charging connector is obtained;

[0059] Determine whether the temperature detection value is greater than a preset reference temperature value;

[0060] If the temperature detection value is not greater than the reference temperature value, continue to obtain the temperature detection value;

[0066] If the ambient temperature is greater than the preset reference temperature, the actual blowing power will continue to be output;

[0067] If the ambient temperature value is not greater than the preset reference ambient temperature value, the startup number corresponding to the preset windward device is determined according to the ambient wind direction information, and the corresponding windward device is controlled to start based on the startup number;

[0068] Retrieving the surrounding wind speed based on the surrounding environment detection information;

[0069] The actual blowing power is updated according to the surrounding wind speed, and the operation of the blowing device is controlled based on the updated actual blowing power.

[0070] By adopting the above technical scheme, the temperature detection value is compared with the reference temperature value, and the ambient temperature value is compared with the reference ambient temperature value. The start number and the new actual blowing power are obtained based on the comparison result and the surrounding wind direction information, and the blowing device is controlled to operate with the new actual blowing power, so that the charging connector can be cooled with the help of natural wind to reduce energy consumption.

[0071] Optionally, the method for obtaining the actual image information on the charging connector is also included:

[0072] Based on the image detection information, an image corresponding to a preset character feature is selected by framing the selected image, and the selected image is used as character image information;

[0075] Matching a reference lifting height from a preset lifting database based on the person's height information;

[0076] Determine the interface height between the interface and the ground according to the vehicle interface model;

[0077] When the actual vertical height is less than the interface height value, the auxiliary blowing power is determined according to the corresponding relationship between the interface height value and the reference lifting height;

[0078] Based on the auxiliary blowing power control, the auxiliary blowing device preset on the holding part is operated until the charging connector outputs the preset charging trigger information.

[0079] By adopting the above technical solution, the actual vertical height is compared with the interface height value, the auxiliary blowing power is obtained based on the comparison result and the benchmark lifting height, and the auxiliary blowing device is controlled to operate with the auxiliary blowing power, so that the user can conveniently take the charging connector and insert it into the interface on the vehicle to charge the vehicle.

[0080] Optionally, the method further includes controlling the auxiliary blowing device preset on the holding part to operate:

[0081] When the actual vertical height is consistent with the interface height value, a shape corresponding to the interface feature is selected based on the actual image information, and the selected shape is used as the actual interface shape;

[0103] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0104] A control method for a megawatt-class ultrafast charging system, which obtains a connector of a corresponding model by understanding an interface on a vehicle and prompts a user to take it to charge the vehicle, and further adjusts the charging connector according to the color of the charging connector, parameters of the surrounding environment, the temperature of the charging connector, and the height between the gripping part and the ground, thereby facilitating the widespread use of the megawatt-class ultrafast charging system and preventing abnormal charging from occurring.

[0105] Reference Figure 1 The present application embodiment discloses a control method for a megawatt-class ultra-fast charging system, comprising the following steps:

[0106] Step S100: Obtain image detection information of a megawatt-class ultra-fast charging pile within a preset charging range.

[0107] The charging range refers to the range within which a megawatt-class ultra-fast charging pile charges a vehicle. The charging range is set in advance by those skilled in the art and will not be described in detail here. The image detection information refers to the image corresponding to the charging range. The image corresponding to the charging range is captured by a camera preset on the megawatt-class ultra-fast charging pile as the image detection information. The image detection information includes the charging connector on the megawatt-class ultra-fast charging pile, the gripping part, and the vehicle within the charging range.

[0108] Step S101: When a preset vehicle feature appears in the image detection information, an image corresponding to the preset interface feature is framed based on the image detection information, and the framed image is used as the interface image information.

[0109] Vehicle features refer to the shape and license plate of the vehicle, and interface features refer to the shape and other features of the interface on the vehicle for plugging into the charging interface and charging. Vehicle features and interface features are set in advance by those skilled in the art and will not be described in detail here. Interface image information refers to the image corresponding to the interface on the vehicle. When vehicle features appear in the image detection information, it means that a vehicle needs to be charged, so the image corresponding to the interface features is selected from the image detection information as the interface image information.

[0110] Step S102: Determine the vehicle interface model according to the interface image information.

[0111] The vehicle interface model refers to the model of the corresponding interface on the vehicle. The matching vehicle interface model is queried from the preset interface database through the interface image information. The interface database stores vehicle interface models corresponding to different interface image information. The interface database is a manually set database and will not be elaborated here.

[0112] Step S103: Matching the connector type from a preset interface database based on the vehicle interface model.

[0113] The connector type refers to the type of connector that can be used with the vehicle interface model. The matching connector type is queried from the interface database through the vehicle interface model. The interface database stores the connector types corresponding to different vehicle interface models, which will not be described here. The connector type includes information such as the shape, charging protocol, and charging power corresponding to the connector.

[0114] Step S104: Determine different reference charging information according to the connector type.

[0115] The reference charging information refers to the reference information such as the charging protocol and charging power corresponding to the connector type, and is formed by combining different charging protocols and charging power reference information from the connector type. In this embodiment, one type of connector contains multiple reference charging information.

[0116] Step S105: Determine vehicle charging information based on the image detection information.

[0117] Vehicle charging information refers to the charging protocol and charging power corresponding to the vehicle that needs to be charged. The shape and license plate and other information corresponding to the vehicle features are identified from the image detection information, and the vehicle charging information is matched from a preset vehicle database through the identified information. The vehicle database stores the vehicle charging information of the vehicles corresponding to the shapes and license plates and other information corresponding to each vehicle. The vehicle database is a manually set database and will not be elaborated here.

[0118] Step S106: Based on the vehicle charging information, a connector type corresponding to the reference charging information is selected from different connector types, and the selected connector type is defined as an actual connector model.

[0119] The actual connector model refers to the connector model actually required to charge the vehicle, by selecting the connector type corresponding to the consistency between the reference charging information and the vehicle charging information from different connector types, and using the selected connector type as the actual connector model.

[0120] Step S107: controlling the preset connector device to be installed according to the actual connector model, and outputting a preset prompt message to prompt the user to charge the vehicle.

[0121] The connector device refers to a device that is equipped with different connectors and stores the reference charging information corresponding to each connector. When the actual connector model is output, the connector device installs the connector of the corresponding model on the charging connector to realize charging of the current vehicle. Prompt information refers to information used to prompt the user to unplug and use the charging connector to charge the vehicle. The prompt information is set in advance by technical personnel in this field and will not be repeated here. By outputting prompt information to prompt the user to charge the vehicle, it is convenient for the user to use the same megawatt-class ultra-fast charging pile to charge different models, so as to facilitate the widespread use of megawatt-class ultra-fast charging systems.

[0122] Reference Figure 2 , and also includes a method for prompting the user to charge the vehicle:

[0123] Step S200: When the user inserts the charging connector into the interface, determine whether the megawatt-class ultra-fast charging pile has a charging abnormality.

[0124] When the user inserts the charging connector into the interface, it indicates that the megawatt-class ultra-fast charging pile is delivering electricity to the vehicle, so it is determined whether the megawatt-class ultra-fast charging pile has an abnormality that prevents charging, and thus whether there are abnormalities such as foreign matter in the charging connector.

[0125] Step S201: If the megawatt-class ultra-fast charging pile has no charging abnormality, continue to output vehicle charging information to continue charging the vehicle.

[0126] When there is no charging abnormality at the megawatt-class ultra-fast charging pile, it means that there is no foreign object on the charging connector, so the vehicle charging information continues to be output to continue charging the vehicle.

[0127] Step S202: If a charging abnormality occurs in the megawatt-class ultra-fast charging pile, a preset abnormality message is output to prompt the user to insert the charging connector into a preset cleaning device.

[0128] Abnormal information refers to information used to prompt the user that an abnormality has occurred on the charging connector and that the charging connector needs to be inserted into a preset cleaning device. The abnormal information is set in advance by those skilled in the art and will not be described in detail here. The cleaning device refers to a device corresponding to cleaning foreign matter on the charging connector, and the cleaning device is provided with a socket for inserting the charging connector. When a charging abnormality occurs on a megawatt-class ultra-fast charging pile, it indicates that the megawatt-class ultra-fast charging pile is damaged or there are foreign matter on the charging connector, so the abnormal information is output to prompt the user to insert the charging connector into the cleaning device to clean the charging connector.

[0129] Step S203: Obtaining the connector image information and abnormal position before the charging connector is inserted into the cleaning device.

[0130] The connector image information refers to the image corresponding to the charging connector. Before the charging connector is inserted into the cleaning device, the camera preset on the cleaning device identifies the features corresponding to the charging connector and takes a photo, and the taken image is used as the connector image information. The abnormal position refers to the position where foreign matter adheres to the charging connector. The position where the charging connector outputs abnormality is retrieved from the system as the abnormal position.

[0131] Step S204: Retrieving the joint color information corresponding to the abnormal position based on the joint image information.

[0132] The connector color information refers to the color information corresponding to the connector installed on the charging connector, and the color of the connector corresponding to the abnormal position is retrieved from the connector image information as the connector color information.

[0133] Step S205: matching the connector color parameters from a preset color database based on the connector color information.

[0134] The connector color parameter refers to the color concentration corresponding to the connector color information. The connector color parameter is matched from a preset color database through the connector color information. The color database stores the concentrations corresponding to different colors. The color database is a database set by humans and will not be described in detail here.

[0135] Step S206: Calculate a color deviation parameter according to the joint color parameter and a preset reference color parameter.

[0136] The reference color parameter refers to the reference concentration corresponding to the connector installed on the charging connector. The reference color parameter is set in advance by a person skilled in the art and will not be described in detail here. The difference between the connector color parameter and the reference color parameter is calculated and the difference is used as the color deviation parameter.

[0137] Step S207: When the color deviation parameter is greater than the preset reference deviation parameter, matching the vibration power from the preset vibration database based on the color deviation parameter.

[0138] The reference deviation parameter refers to the maximum deviation concentration of the connector installed on the charging connector that affects charging. The reference deviation parameter is set in advance by a person skilled in the art and will not be described in detail here. The vibration power refers to the power of the vibration device. When the color deviation parameter is greater than the reference deviation parameter, it means that the dust on the charging connector affects the charging of the vehicle. The vibration power is matched from a preset vibration database through the color deviation parameter. The vibration database stores the vibration powers corresponding to different color deviation parameters. The vibration database is a manually set database and will not be described in detail here. The vibration device refers to a device corresponding to cleaning dust on the charging connector. The vibration device is a micro-oscillator that is arranged in the cleaning device and installed around the socket on the cleaning device.

[0139] Step S208: Controlling the vibration device preset in the cleaning device to vibrate according to the vibration power and the abnormal position to clean the dust.

[0140] The vibration device is controlled to vibrate through vibration power and abnormal position to clean the dust on the charging connector, thereby cleaning the dust on the charging connector, and it is not easy to cause abnormal charging in the megawatt-level ultra-fast charging pile.

[0141] Reference Figure 3 , the method after controlling the vibration device preset in the cleaning device to vibrate to clean the dust includes:

[0142] Step S300: After the vibration device vibrates, the preset clamping device is controlled to clamp the charging device to a preset reset position, and it is determined whether there is a color deviation parameter in the connector image information.

[0143] The clamping device refers to a manipulator for clamping the charging connector, and the reset position refers to a position for placing the charging connector and checking whether the charging connector has been cleaned. The reset position is set in advance by a person skilled in the art and will not be described in detail here. After the vibration device vibrates, the clamping device is controlled to clamp the charging device to the reset position, and it is determined whether there is a color deviation parameter in the connector image information, thereby determining whether the charging connector has been cleaned.

[0144] Step S301: If there is no color deviation parameter in the joint image information, the preset prompt information continues to be output.

[0145] When there is no color deviation parameter in the connector image information, it means that the charging connector has been cleaned, so the prompt information continues to be output to prompt the user to continue charging the vehicle.

[0146] Step S302: If there is a color deviation parameter in the connector image information, a humidity detection value on the charging connector is obtained.

[0147] The humidity detection value refers to the humidity value on the charging connector. When there is a color deviation parameter in the connector image information, it means that the charging connector has not been cleaned. Therefore, the humidity sensor is used to detect the parameter on the charging connector as the humidity detection value.

[0148] Step S303: when the humidity detection value is greater than a preset reference humidity value, the humidity distribution position is determined according to the humidity detection value and the joint image information.

[0149] The reference humidity value refers to the minimum humidity value corresponding to dust adhering to the charging connector. The reference humidity value is set in advance by a technician in this field and will not be described here. The humidity distribution position refers to the position of the humidity detection value on the charging connector. When the humidity detection value is not greater than the reference humidity value, it means that the dust is adhering to the charging connector and is not easy to clean, and there are no water droplets on the charging connector to affect the charging of the vehicle. Therefore, the preset erasing device is directly controlled to erase the abnormal position. The erasing device refers to a mechanical arm corresponding to a sponge or rag that is clamped to erase foreign matter such as water droplets and dust on the charging connector. When the humidity detection value is greater than the reference humidity value, it means that the dust is adhering to the charging connector and is not easy to clean, and there are water droplets on the charging connector to affect the charging of the vehicle. Therefore, the position corresponding to the parameter detected by the humidity sensor on the charging connector is combined with the connector image information to obtain the humidity distribution position.

[0150] Step S304: When the humidity distribution position does not coincide with the abnormal position, an erasing path is determined according to the humidity distribution position and a preset joint specification.

[0151] The connector specification refers to the shape and size specifications corresponding to the connector on the charging connector. The connector specifications are set in advance by technicians in this field and will not be described here. The erasing path refers to the path taken by the erasing device to erase foreign matter such as water droplets and dust on the charging connector. When the humidity distribution position coincides with the abnormal position, it means that the dust adheres to the charging connector through water droplets, so the erasing device is directly controlled to erase the abnormal position. When the humidity distribution position does not coincide with the abnormal position, it means that the dust does not adhere to the charging connector through water droplets, so the connector shape is formed by the connector specifications, and the humidity distribution position is combined with the shape of the connector to obtain the erasing path.

[0152] Step S305: controlling a preset erasing device to perform erasing based on the erasing path, and determining the moisture adsorption position according to the humidity distribution position and the erasing specification of the preset erasing device.

[0153] The erasing specification refers to the size specification corresponding to the erasing device. The erasing specification is set in advance by a person skilled in the art and will not be described in detail here. The moisture adsorption position refers to the position where the erasing device adsorbs moisture. When the erasing path controls the erasing device to perform erasing, the size that fits the charging connector is retrieved from the erasing specification to form an erased shape range, and the erased shape range is combined with the humidity distribution position to obtain the position on the erasing device where moisture is adsorbed as the moisture adsorption position.

[0154] Step S306: updating the erasing path according to the moisture adsorption position and the abnormal position, and controlling the preset erasing device to erase the dust based on the updated erasing path.

[0155] The parameters of the erasing device corresponding to the overlap of the moisture adsorption position with the abnormal position are obtained, and the offset parameters are combined with the erasing path to obtain a new erasing path. The erasing device is controlled to erase dust through the updated erasing path, so that the erasing device that adsorbs moisture can erase the dust, further improving the efficiency of dust erasing.

[0157] Step S400: Obtaining the surrounding environment detection information of the megawatt-class ultra-fast charging pile.

[0158] The surrounding environment detection information refers to the temperature, humidity, wind direction and speed and other information of the environment surrounding the megawatt-class ultra-fast charging pile. The parameters of the surrounding environment are detected by sensors such as temperature sensors, humidity sensors and wind direction sensors preset on the megawatt-class ultra-fast charging pile, and the various parameters are combined to obtain the surrounding environment detection information.

[0159] Step S401: Retrieve the ambient humidity value based on the ambient environment detection information.

[0160] The ambient humidity value refers to the humidity value of the environment surrounding the megawatt-class ultra-fast charging pile, and the ambient humidity value is retrieved from the surrounding environment detection information.

[0161] Step S402: When the ambient humidity value is greater than a preset reference ambient humidity value, obtain ambient wind direction information based on ambient environment detection information.

[0162] The reference environmental humidity value refers to the maximum humidity value of the surrounding environment when it is about to rain. The reference environmental humidity value is set in advance by those skilled in the art and will not be described in detail here. The surrounding wind direction information refers to the natural wind direction of the surrounding environment of the megawatt-class ultra-fast charging pile. When the surrounding humidity value is not greater than the reference environmental humidity value, it means that the surrounding environment has not rained yet, so continue to obtain the surrounding environment detection information. When the surrounding humidity value is greater than the reference environmental humidity value, it means that the surrounding environment has already rained, so the surrounding wind direction information is retrieved from the surrounding environment detection information.

[0163] Step S403: Determine whether the surrounding wind direction information is consistent with the preset reference wind direction information.

[0164] The reference wind direction information refers to the direction in which the natural wind in the surrounding environment of the megawatt-class ultra-fast charging pile blows toward the charging connector. The reference wind direction information is set in advance by those skilled in the art and will not be described in detail here. By determining whether the surrounding wind direction information is consistent with the reference wind direction information, it is determined whether the natural wind in the surrounding environment blows rainwater toward the charging connector.

[0165] Step S404: If the surrounding wind direction information is inconsistent with the reference wind direction information, continue to obtain surrounding environment detection information.

[0166] When the surrounding wind direction information is inconsistent with the reference wind direction information, it means that the natural wind in the surrounding environment has not blown the rain to the charging connector, so the surrounding environment detection information continues to be obtained.

[0167] Step S405: If the surrounding wind direction information is consistent with the reference wind direction information, the shielding position is determined according to the surrounding wind direction information and a preset reset position.

[0168] The shielding position refers to the position of the shielding device used to shield rainwater. When the surrounding wind direction information is consistent with the reference wind direction information, it means that the natural wind in the surrounding environment blows rainwater to the charging connector. Therefore, the shielding position is matched from the preset shielding database through the surrounding wind direction information and the reset position. The shielding database stores shielding positions corresponding to different surrounding wind direction information and reset positions. The shielding database is a database set by humans and will not be described in detail here. The shielding device refers to a mechanical arm used to shield the charging connector and equipped with a baffle.

[0169] Step S406: controlling a preset shielding device according to the shielding position to shield the charging connector.

[0170] By controlling the shielding device to operate in the shielding position, it is not easy for rainwater to drip onto the charging connector to cause abnormal charging.

[0172] Step S500: Retrieve interface color information based on the interface image information.

[0173] The interface color information refers to the color information corresponding to the interface on the vehicle, and the interface color information is retrieved from the interface image information.

[0174] Step S501: Determine the interface reference color according to the vehicle interface model.

[0175] The interface reference color refers to the reference color corresponding to the interface on the vehicle, and the interface reference color is matched from a preset vehicle database according to the vehicle interface model. The vehicle database stores the interface reference colors corresponding to different vehicle interface models, which will not be described in detail here.

[0176] Step S502: matching interface color parameters from a preset color database based on the interface color information, and matching reference interface color parameters from a preset color database based on the interface reference color.

[0177] The interface color parameter refers to the color concentration corresponding to the interface color information, and the interface color parameter is matched from the color database through the interface color information. The reference interface color parameter refers to the color concentration corresponding to the interface reference color, and the reference interface color parameter is matched from the color database through the reference interface color parameter. The color database also stores the corresponding relationship between the interface color information, the interface reference color, the interface color parameter, and the reference interface color parameter, which will not be described in detail here.

[0178] Step S503: Calculate the interface color deviation parameter according to the interface color parameter and the reference interface color parameter.

[0179] The interface color deviation parameter refers to the deviation value between the interface color parameter and the reference interface color parameter. The difference between the interface color parameter and the reference interface color parameter is calculated and the difference is used as the interface color deviation parameter.

[0180] Step S504: Determine the dust coverage of the interface according to the interface color deviation parameter.

[0181] The interface dust coverage refers to the degree of dust coverage corresponding to the interface on the vehicle. The interface dust coverage is matched from a preset dust database through the interface color deviation parameter. The dust database stores the interface dust coverage corresponding to different interface color deviation parameters. The dust database is a manually set database and will not be described in detail here.

[0182] Step S505: matching the connector blowing power from a preset blowing database according to the dust coverage of the interface.

[0183] The connector blowing power refers to the power of the blowing device on the charging connector to blow air to the interface. The connector blowing power is matched from the preset blowing database according to the dust coverage degree of the interface. The blowing database stores the connector blowing powers corresponding to different degrees of interface dust coverage. The blowing database is a manually set database and will not be described here. The blowing device refers to a device installed on the charging connector and used to blow air to the interface. The blowing device also includes a number of air outlets evenly opened on the outer side wall of the charging connector. The air outlets are used to discharge the wind generated by the blowing device to achieve wind circulation, thereby further improving the cooling efficiency of the blowing device.

[0184] Step S506: Acquire actual image information on the charging connector.

[0185] The actual image information refers to the image of the interface on the vehicle captured by the charging connector, and the image of the insertion direction of the charging connector captured by a miniature camera preset on the charging connector is used as the actual image information.

[0186] Step S507: When a complete interface feature appears in the actual image information, the actual distance value between the charging connector and the vehicle is obtained.

[0187] The actual distance value refers to the actual distance value between the charging connector and the vehicle. When the complete interface features do not appear in the actual image information, it means that the charging connector is not aligned with the interface on the vehicle, so the actual image information is continued to be acquired. When the complete interface features appear in the actual image information, it means that the charging connector is aligned with the interface on the vehicle, so the distance parameter of the insertion direction detected by the infrared sensor preset on the charging connector is used as the actual distance value.

[0188] Step S508: When the actual distance value is less than the preset reference distance value, based on the connector blowing power, the blowing device preset on the charging device is controlled to blow air until the charging connector outputs the preset charging trigger information.

[0189] The reference distance value refers to the maximum distance value for the blowing device to blow air. The reference distance value is set in advance by those skilled in the art and will not be described in detail here. The charging trigger information refers to the information that the charging connector is inserted into the interface on the vehicle to charge the vehicle. The charging trigger information is set in advance by those skilled in the art and will not be described in detail here. When the actual distance value is not less than the reference distance value, it means that the charging connector is not inserted into the interface on the vehicle, so the blowing device is not started. When the actual distance value is less than the reference distance value, it means that the charging connector is inserted into the interface on the vehicle, so the blowing device is controlled to blow air at the connector blowing power until the charging connector outputs the charging trigger information.

[0190] Also included is a method for controlling the blowing device to blow air:

[0191] Step S600: When the charging connector outputs a preset charging trigger message, the blowing device is stopped and a temperature detection value in the charging connector is obtained.

[0192] The temperature detection value refers to the temperature value inside the charging connector. When the charging connector outputs the preset charging trigger information, it means that the megawatt-level ultra-fast charging pile is charging the vehicle, so the blowing device is stopped and the parameter obtained by detecting the temperature sensor preset in the charging connector is used as the temperature detection value.

[0193] Step S601: Determine whether the temperature detection value is greater than a preset reference temperature value.

[0194] The reference temperature value refers to the minimum temperature value corresponding to the impact of the megawatt-class ultra-fast charging pile on the charging efficiency of the vehicle. The reference temperature value is set in advance by those skilled in the art and will not be described in detail here. By determining whether the temperature detection value is greater than the reference temperature value, it is determined whether the temperature generated by the charging connector when the megawatt-class ultra-fast charging pile rebuilds the vehicle affects the charging efficiency of the vehicle.

[0195] Step S602: If the temperature detection value is not greater than the reference temperature value, continue to obtain the temperature detection value.

[0196] When the temperature detection value is not greater than the reference temperature value, it indicates that the temperature generated by the charging connector has no effect on the charging efficiency of the vehicle, so the temperature detection value continues to be obtained.

[0197] Step S603: if the temperature detection value is greater than the reference temperature value, the actual blowing power is matched from a preset blowing database based on the temperature detection value.

[0198] The actual blowing power refers to the actual power of the blowing device on the charging connector. When the temperature detection value is greater than the reference temperature value, it means that the temperature generated by the charging connector affects the charging efficiency of the vehicle. Therefore, the actual blowing power is matched from a preset blowing database through the temperature detection value. The blowing database stores the actual blowing power corresponding to different temperature detection values. The blowing database is a manually set database and will not be elaborated here.

[0199] Step S604: Determine the connector insertion position according to the interface image information and the image detection information.

[0200] The connector insertion position refers to the position corresponding to the interface on the vehicle where the charging connector is inserted, and the position of the interface image information on the image detection information is used as the connector insertion position.

[0201] Step S605: Determine auxiliary cooling wind direction information according to the connector insertion position and the reference wind direction information.

[0202] The auxiliary cooling wind direction information refers to the natural wind direction used to assist in cooling the charging connector. The wind directions on both sides of the connector insertion position are retrieved from the reference wind direction information as the auxiliary cooling wind direction information.

[0203] Step S606: When the ambient wind direction information is consistent with the auxiliary cooling wind direction information, the ambient temperature value is retrieved based on the ambient environment detection information.

[0204] The ambient temperature value refers to the temperature value of the environment around the megawatt-class ultra-fast charging pile. When the ambient wind direction information is inconsistent with the auxiliary cooling wind direction information, it means that the natural wind cannot assist in cooling the charging connector, so the actual blowing power continues to be output. When the ambient wind direction information is consistent with the auxiliary cooling wind direction information, it means that the natural wind can assist in cooling the charging connector, so the ambient temperature value is retrieved from the ambient environment detection information.

[0205] Step S607: Determine whether the ambient temperature value is greater than a preset reference ambient temperature value.

[0206] The reference ambient temperature value refers to the reference temperature value at which natural wind can cool the charging connector. The reference ambient temperature value is set in advance by a person skilled in the art and will not be described in detail herein. By determining whether the ambient temperature value is greater than the reference ambient temperature value, it is determined whether natural wind can cool the charging connector.

[0207] Step S608: If the ambient temperature is greater than the preset reference ambient temperature, the actual blowing power continues to be output.

[0208] When the ambient temperature is greater than the reference ambient temperature, it means that the natural wind cannot cool the charging connector, so the actual blowing power continues to be output.

[0209] Step S609: If the ambient temperature value is not greater than the preset reference ambient temperature value, the startup number corresponding to the preset windward device is determined according to the ambient wind direction information, and the corresponding windward device is controlled to start based on the startup number.

[0210] The windward device refers to a hole opened on the charging connector and used to receive natural wind to cool the charging connector and can be opened and closed. The start-up number refers to the start-up number of the windward device. When the ambient temperature value is not greater than the reference ambient temperature value, it means that the natural wind can cool the charging connector. Therefore, the number of the windward device corresponding to the ambient wind direction information is used as the start-up number, and the start-up number is used to control the start-up of the corresponding windward device, so that the natural wind can be received to assist in cooling the charging connector.

[0211] Step S610: Retrieve the surrounding environment wind speed based on the surrounding environment detection information.

[0212] The ambient wind speed refers to the wind speed in the surrounding environment of the megawatt-class ultra-fast charging pile, which is obtained by retrieving the ambient wind speed from the surrounding environment detection information.

[0213] Step S611: updating the actual blowing power according to the ambient wind speed, and controlling the operation of the blowing device based on the updated actual blowing power.

[0214] The new actual blowing power is matched from the preset blowing database according to the ambient wind speed. The actual blowing power corresponding to different ambient wind speeds is stored in the blowing database, which will not be described in detail here. By controlling the blowing device to operate with the updated actual blowing power, the charging connector can be cooled with the assistance of natural wind while reducing energy consumption.

[0215] It also includes the method for obtaining the actual image information on the charging connector:

[0216] Step S700: based on the image detection information, an image corresponding to a preset character feature is selected by framing, and the selected image is used as character image information.

[0217] Character features refer to the shape, color and other features corresponding to a character. Character features are set in advance by a person skilled in the art and will not be described in detail here. Character image information refers to the image corresponding to a character within the charging range. The image corresponding to the character features is selected from the image detection information as the character image information.

[0218] Step S701: determining the person's height information according to the person's image information and a preset reference ratio.

[0219] The reference ratio refers to the ratio used to calculate the actual size of the image objects and characters. The reference ratio is set in advance by those skilled in the art and will not be described in detail here. The character height information refers to the actual height of the characters within the charging range. The character height information is calculated by the size parameters of the image corresponding to the character image information and the reference ratio.

[0220] Step S702: Acquire the actual vertical height between the gripping part and the ground.

[0221] The actual vertical height refers to the actual height between the gripping part and the ground, and the distance parameter corresponding to the vertical distance to the ground is detected by the infrared sensor preset on the gripping part as the actual vertical height.

[0222] Step S703: matching a reference lifting height from a preset lifting database based on the person's height information.

[0223] The reference lifting height refers to the height value with the least effort corresponding to the height information of the person, and the reference lifting height is matched from the preset lifting database through the height information of the person. The lifting database stores the estimated lifting heights corresponding to different height information of the person. The lifting database is a database set by humans and will not be described in detail here. In this embodiment, the reference lifting height can be the height above the waist corresponding to the person.

[0224] Step S704: Determine the interface height value between the interface and the ground according to the vehicle interface model.

[0225] The interface height value refers to the height value between the interface on the vehicle and the ground. The interface height value is matched from a preset vehicle database according to the vehicle interface model. The vehicle database stores interface height values ​​corresponding to different vehicle interface models.

[0226] Step S705: When the actual vertical height is less than the interface height value, the auxiliary blowing power is determined according to the corresponding relationship between the interface height value and the reference lifting height.

[0227] The auxiliary blowing power refers to the power of the auxiliary blowing device. When the actual vertical height is not less than the interface height value, it means that the auxiliary blowing device is not needed for blowing, so the actual vertical height continues to be obtained. When the actual vertical height is less than the interface height value, it means that the auxiliary blowing device is needed for blowing, so the auxiliary blowing power is matched from the preset auxiliary blowing database through the interface height value and the reference lifting height. The auxiliary blowing database stores the auxiliary blowing powers corresponding to different interface height values ​​and reference lifting heights. The auxiliary blowing database is a manually set database and will not be described here.

[0228] The auxiliary blowing device refers to a blowing device that is arranged at the holding position and blows toward the ground to assist the user in picking up the charging connector.

[0229] Step S706: Based on the auxiliary blowing power, the auxiliary blowing device preset on the holding part is controlled to operate until the charging connector outputs the preset charging trigger information.

[0230] By controlling the auxiliary blowing device to operate at the auxiliary blowing power until the charging connector outputs a preset charging trigger information, it is convenient for the user to take the charging connector and insert it into the interface on the vehicle to charge the vehicle.

[0231] Also included is a method for controlling the operation of an auxiliary blowing device preset on the gripping part:

[0232] Step S800: When the actual vertical height is consistent with the interface height value, a shape corresponding to the interface feature is selected based on the actual image information, and the selected shape is used as the actual interface shape.

[0233] The actual interface shape refers to the shape of the vehicle interface that appears in the actual image information. When the actual vertical height is consistent with the interface height value, it means that the charging connector is about to be inserted into the interface on the vehicle. Therefore, the shape corresponding to the interface feature is selected from the actual image information as the actual interface shape.

[0234] Step S801: Retrieve a reference interface shape based on the vehicle interface model.

[0235] The reference interface shape refers to the reference shape corresponding to the interface on the vehicle, and the reference interface shape is retrieved from the vehicle interface model.

[0236] Step S802: determining a vector offset angle according to the actual interface shape and the reference interface shape.

[0237] The vector offset angle refers to the angle of rotational offset between the actual interface shape and the reference interface shape. The actual interface shape is compared with the reference interface shape, and the deviation angle between the corresponding lines in the actual interface shape and the reference interface shape is used as the vector offset angle.

[0238] Step S803: updating the auxiliary blowing power according to the vector offset angle.

[0239] The new auxiliary blowing power is matched from the preset auxiliary blowing database through the vector offset angle, so that the force of the auxiliary blowing device blowing toward the ground can be kept unchanged when the blowing angle of the auxiliary blowing device is changed.

[0240] Step S804: controlling the auxiliary blowing device to operate according to the vector offset angle and the updated auxiliary blowing power until the charging connector outputs a preset charging trigger information.

[0241] By controlling the auxiliary blowing device to operate with a vector offset angle and an updated auxiliary blowing power until the charging connector outputs a preset charging trigger information, the user can be guided to adjust the charging connector to normal to facilitate the insertion of the charging connector into the interface on the vehicle.
