Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of charging piles, and in particular to an automatic charging method and device based on the combination of charging piles and ETC. BACKGROUND

[0002] With the rapid development of new energy vehicles, the demand for charging piles is also increasing. At present, the payment methods for new energy vehicles at charging piles mainly include code scanning payment and card swiping payment. These traditional payment methods are cumbersome, and the vehicle owner often needs to manually operate the payment application to scan the code or take out a special charging card to swipe the card. From the start of operation to the start of charging, the average time consumption is more than 3 minutes. Moreover, since different charging piles may belong to different operation platforms, each platform has an independent account system, which leads to the need for users to pre-charge in multiple platforms, greatly reducing the convenience of payment.

[0003] In some specific scenarios, the payment problem is more prominent. For example, in a highway service area, due to heavy traffic, geographical location, and other factors, the network signal is usually poor. In such an environment, the use of code scanning payment has a significantly increased payment failure rate. Once the payment fails, the vehicle owner needs to try repeatedly, which not only wastes his own time but also prolongs the occupancy time of the charging pile.

[0004] Electronic Toll Collection (ETC) is an electronic non-stop toll collection system that has been widely used in the field of highway toll collection. It has the characteristics of speed, convenience, and no need for manual intervention. However, the current ETC system is mainly applied to the scene of highway toll collection and has not been combined with the payment scene of charging piles. SUMMARY

[0005] The present application provides an automatic charging method and device based on the combination of charging piles and ETC, which can effectively solve the problems of signal interference, identity misrecognition, and resource conflict when multiple parking spaces are concurrently charged, ensuring the stability and security of ETC non-inductive payment in the multi-parking space scenario, while maintaining the convenience of the user's "plug and charge" experience.

[0006] In a first aspect, the application provides an automatic charging method based on the combination of charging piles and ETC. The method is applied to a charging pile in an automatic charging system, the automatic charging system comprising the charging pile, a vehicle and a cloud management platform.

[0007] In a second aspect, the application provides an automatic charging system, which comprises a charging pile, a vehicle and a cloud management platform. The charging pile comprises a charging pile ETC module and at least two charging plugs, and the vehicle comprises a vehicle-mounted ETC module. The charging pile is used to execute the step instructions in the method of any one of the first aspect.

[0008] In a third aspect, the application provides an automatic charging device based on the combination of charging piles and ETC, which is applied to a charging pile in an automatic charging system. The automatic charging system comprises the charging pile, a vehicle and a cloud management platform. The charging pile comprises a charging pile ETC module, and the vehicle comprises a vehicle-mounted ETC module. The charging pile is used to execute the step instructions in the method of any one of the first aspect. The device comprises: an acquisition unit, which is used to acquire parking space information and activation time corresponding to at least two activation signals after detecting the at least two activation signals within a preset time. The activation signal is used to represent the connection state of the charging plug of the charging pile and the vehicle. A processing unit is used to determine the communication priority order of each parking space according to the parking space information and the activation time, and allocate the communication time slot of each parking space. A communication priority queue is established according to the communication priority order and the communication time slot. The charging pile ETC module and the vehicle-mounted ETC module of each parking space are controlled to execute a verification program according to the communication priority queue. The acquisition unit is also used to receive a verification pass instruction from the cloud management platform, start charging the vehicle, acquire charging data, and send the charging data to the cloud management platform. A sending unit is used to receive a stop charging instruction, send an automatic charge deduction instruction to the cloud management platform, and complete the charge deduction operation.

[0009] In a fourth aspect, the application provides a server comprising a processor and a memory. The memory stores a computer program. When the processor invokes the computer program in the memory, the steps in the method of any one of the first aspect are executed.

[0010] As can be seen, in the embodiments of the application, the charging pile acquires parking space information and activation time corresponding to at least two activation signals after detecting the at least two activation signals within a preset time. The activation signal is used to represent the connection state of the charging plug of the charging pile and the vehicle. The communication priority order of each parking space is determined according to the parking space information and the activation time, and the communication time slot of each parking space is allocated.

[0023] ETC adopts 5.8GHz dedicated short-range communication (DSRC) technology to realize wireless interaction, and when a single charging pile covers multiple parking spaces, the spatial distance of two parking spaces is usually close (such as 2-3 meters), which will cause the DSRC signal coverage of the two parking spaces to be highly overlapped, causing the following key problems:

[0024] 1) Signal cross interference, leading to communication failure: when two parking spaces simultaneously insert a gun to trigger charging, the ETC sensing module of the charging pile will simultaneously send an“inquiry signal” to the vehicles of the two parking spaces, and the two vehicle-mounted ETC modules will also simultaneously return encrypted information. At this time, the overlapped 5.8GHz signals will interfere with each other (such as signal superposition, phase conflict), which may cause the charging pile to be unable to accurately receive the complete information of any vehicle-mounted ETC module, resulting in“communication timeout” or“information frame break”, and the charging start being stuck.

[0025] 2) Identity misidentification, wrong matching of vehicles and accounts: If the vehicles in two parking spaces are too close (e.g., parked tightly in adjacent parking spaces), the ETC module of the charging pile may not accurately distinguish the signal sources of the two vehicle-mounted ETC modules: for example, the vehicle-mounted ETC module information of the A parking space vehicle is misidentified as that of the B parking space, resulting in the problem of wrong deduction of "B parking space charging and deduction of A parking space account fees"; more seriously, it may occur that "two accounts are simultaneously bound to the same charging parking space", causing subsequent billing confusion.

[0026] To solve the above technical problems, the present application provides an automatic charging method and device based on the combination of charging piles and ETC, which fuses a dynamic time slot allocation algorithm to construct an ETC non-inductive charging system with "vehicle-pile-cloud" cooperation, effectively solving the problems of signal interference, identity misidentification, resource conflict, etc. in the case of multi-parking space concurrent charging, ensuring the stability and security of ETC non-inductive payment in the multi-parking space scenario, while maintaining the convenience of user "plug and charge".

[0027] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes may not be described again in some examples. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0028] Please refer to Figure 1 , Figure 1 The structure of an automatic charging system provided by the present application is shown in the schematic block diagram of Figure 1 The automatic charging system includes charging piles, vehicles and a cloud management platform. Each part cooperates with each other to realize the automatic payment process of electric vehicle charging.

[0029] The charging pile is the front-end equipment of the whole system, responsible for charging interaction with the vehicle and data communication with other systems. The charging pile includes at least two charging plugs covering at least two parking spaces, and mainly includes a charging pile ETC module, a charging control module and a billing control unit module. The charging pile ETC module adopts radio frequency identification (RFID) technology, and its working principle is to realize wireless communication with the vehicle-mounted ETC module by using the spatial coupling characteristics of radio frequency signals. The charging pile ETC module has a certain induction distance, generally within 1-3 meters, which can ensure that the ETC account information and vehicle identification information of the vehicle are quickly and accurately obtained when the vehicle approaches the charging pile. In order to reduce the number of invalid identifications of the ETC module (such as the existing technology in which the vehicle passes close by to trigger the ETC module to identify information), in this application, an activation program of the charging pile ETC module is provided, which activates the charging pile ETC module only when the user takes the charging plug off the charging pile or inserts the charging plug into the vehicle, thereby realizing communication interaction with the vehicle-mounted ETC module.

[0030] The charging pile ETC module adopts high-frequency radio frequency signals, commonly 5.8 GHz. At the same time, the module is built-in with signal enhancement and anti-interference circuit, which can effectively resist external electromagnetic interference and ensure the accuracy of information transmission.

[0031] In actual application, the hardware design of the charging pile ETC module needs to consider the problems of heat dissipation and protection. Heat dissipation fins and fans are used for heat dissipation to ensure that the module works normally in high-temperature environment. The shell is designed with waterproof and dustproof, and the protection level reaches IP65 or above to adapt to outdoor harsh environment.

[0032] The charging control module is the core control unit of the charging pile, responsible for controlling the start and stop of the charging process and adjusting the charging parameters. It interacts with the vehicle's battery management system (BMS) in real time to understand the vehicle's charging demand and battery status. During the charging process, the charging control module accurately adjusts the charging current and voltage according to the actual demand of the vehicle and the rated power of the charging pile. For example, when the vehicle battery is low, a larger charging current is used for fast charging; when the battery is close to full, the charging current is gradually reduced to avoid overcharging. The charging control module also has fault diagnosis and protection functions. It monitors the current, voltage, temperature and other parameters in real time, and stops charging immediately and sends an alarm signal once an abnormal condition such as overcurrent, overvoltage, overheating, etc. is found. At the same time, the charging control module can also record fault information to facilitate subsequent maintenance and repair.

[0033] The billing control unit module communicates with the charging control module through CAN on one hand, and obtains the charging related information reported by the vehicle, such as charging power, charging time, current SOC, etc. On the other hand, it communicates with the cloud management platform. In terms of communication mode, the billing control unit module can use Ethernet, GPRS or 4G / 5G, etc. Ethernet is suitable for charging piles with fixed network access, and has the advantages of fast transmission speed and high stability; GPRS and 4G / 5G are suitable for outdoor mobile or remote charging piles, and can realize remote wireless data transmission. In order to ensure the security of data transmission, the billing control unit module uses encryption technology to encrypt the transmitted data. At the same time, in the process of data transmission, retransmission mechanism and verification mechanism are adopted to ensure the integrity and accuracy of data.

[0034] The vehicle includes a vehicle-mounted ETC module installed on the vehicle, which stores the ETC account information and vehicle identification information of the vehicle, and communicates with the charging pile ETC module of the charging pile through wireless communication.

[0035] The vehicle-mounted ETC module is built-in ETC chip and antenna. The ETC chip is the core of the device, responsible for storing and processing the ETC account information and vehicle identification information of the vehicle. The antenna is used for wireless communication with the charging pile ETC module of the charging pile. In order to ensure the stability and reliability of the device, the vehicle-mounted ETC module adopts low-power chip design to prolong the service life of the battery. At the same time, the device shell adopts high-strength plastic material, which has good impact resistance and anti-aging performance. The ETC account information and vehicle identification information stored in the vehicle-mounted ETC module are encrypted using encryption algorithms such as AES encryption algorithm. When communicating with the charging pile ETC module, a secure encryption protocol such as TLS protocol is used to ensure the security of the information during transmission. In actual application, in order to prevent information leakage, the vehicle-mounted ETC module also adopts dynamic key technology. Different encryption keys are generated each time of communication to increase the security of information.

[0036] The cloud management platform includes a charging pile operation platform and an ETC settlement center. The cloud management platform, as the core management platform of the system, is responsible for receiving, processing and storing the data uploaded by the charging pile, calculating the charging fee, and automatically deducting the fee.

[0037] The charging pile operation platform includes a data receiving module, a billing module and a communication module.

[0038] The data receiving module adopts multi-threading technology, which can handle multiple charging piles' data simultaneously. The application of multi-threading technology can improve the efficiency of data reception, ensuring timely and accurate reception and processing of data during peak periods. To ensure the integrity and accuracy of data, the data receiving module adopts data checksum and retransmission mechanism. The received data is checked, and common CRC check is used. If data errors are found, the charging pile is required to resend the data.

[0039] The billing module formulates different billing standards according to different charging periods and charging capacities, realizing flexible billing mode. For example, peak-valley electricity price billing strategy can be adopted to increase the electricity price during peak periods and reduce the electricity price during off-peak periods, guiding users to charge off-peak. The algorithm design of the billing module needs to consider multiple factors, such as charging duration, charging capacity, electricity price policy, etc. In actual application, the billing standards can be flexibly adjusted according to the electricity price policy and market demand of different regions.

[0040] The communication module and the ETC settlement center exchange data through a secure network channel, ensuring the security and reliability of data transmission. The transmitted data is encrypted using SSL / TLS encryption protocol to prevent data from being stolen or tampered during transmission. To ensure the stability of communication, the communication module adopts multi-link backup technology. When the main link fails, it automatically switches to the backup link to ensure the continuity of data transmission.

[0041] The ETC settlement center stores the fund information of ETC accounts, deducts the charging fees from the ETC accounts according to the charging fee information sent by the charging pile operation platform, and feeds back the deduction result. The ETC settlement center stores the fund information of ETC accounts in a distributed database. Distributed database has the characteristics of high scalability and high availability, which can meet the storage and management needs of a large number of ETC account information. In database design, the strategy of partitioning and table is adopted, and the ETC account information is stored in multiple nodes to improve the read-write performance of data. At the same time, data backup and recovery mechanism is adopted to ensure the safety and reliability of data. When deducting the fee, the ETC settlement center adopts double verification mechanism to ensure the accuracy and safety of the deduction. First, the legality of the charging fee information sent by the charging pile operation platform is verified, and the correctness of the fee calculation and the matching of the account information are checked. Then, the real-time query and verification of the fund balance of the ETC account are carried out to ensure that the account has enough funds for deduction. The application of double verification mechanism can effectively prevent the occurrence of mistaken deduction and malicious deduction, and protect the safety of users' funds.

[0042] The system is suitable for various electric vehicle charging scenes, such as highway service areas, urban public charging stations, community parking lots, etc. In particular, in the highway service area, the vehicle flow is large, and the new payment system based on the combination of charging piles and ETC can greatly improve the efficiency of charging payment and reduce the vehicle stay time.

[0043] Referring to Figure 2 , Figure 2 A server structure schematic diagram provided by the embodiment of the application is shown in Figure 2 The server 10 includes a processor 101, a memory 103, a communication interface 102, and a computer program 1031 stored in the memory 103 and configured to be executed by the processor 101. The above program includes an order dynamic allocation method described in each embodiment below.

[0044] Based on the above hardware structure, an automatic charging method based on the combination of charging piles and ETC is provided in the embodiment of the application.

[0045] Referring to Figure 3 , Figure 3 A flowchart of an automatic charging method based on the combination of charging piles and ETC provided by the embodiment of the application is shown in Figure 1 The method is applied to a charging pile in an automatic charging system, and the method includes the following steps S301-S305.

[0046] Step S301: After detecting at least two activation signals within a preset time, the parking space information corresponding to the at least two activation signals and the activation time are obtained.

[0047] The activation signal is used to represent the connection state of the charging plug of the charging pile and the vehicle.

[0048] A single charging pile includes at least two charging plugs and covers at least two parking spaces. In the present application, when the charging plug is inserted into the vehicle or the charging plug is taken out of the charging pile, the charging pile generates an activation signal, which is used to activate the ETC module of the charging pile. When the charging plug is inserted into the vehicle, the vehicle also generates an activation signal, which is used to activate the vehicle-mounted ETC module. In the present embodiment, the ETC modules of the charging pile and the vehicle section need to be triggered to activate, and then communication interaction can be performed. Compared with the existing technology which only senses the distance, the charging recognition accuracy can be improved, the number of false triggers can be effectively reduced, and unnecessary device loss can be reduced.

[0049] The preset time can be an infinitely short time, for example, 0s. If at least two activation signals are detected within the preset time of the charging pile, it indicates that at least two vehicles are charging at the same time in the charging pile. At this time, the communication between the ETC module of the charging pile and the ETC module of at least two vehicles is prone to cross interference due to overlapping signal coverage, resulting in communication failure.

[0050] Therefore, the application establishes a communication priority queue according to the parking space information and the activation time, controls the communication interaction between the ETC module of the charging pile and each vehicle-mounted ETC module according to the order in the communication priority queue and the communication time slot, and solves the communication interference problem in the multi-parking space concurrent charging scene.

[0051] In step S302, the communication priority order of each parking space is determined according to the parking space information and the activation time, and the communication time slot of each parking space is allocated, and a communication priority queue is established according to the communication priority order and the communication time slot.

[0052] The communication time slot allocation needs to combine the communication time length characteristics of the DSRC (Dedicated Short-Range Communication) technology, allocate independent and non-overlapping communication time slots (such as each time slot is 200 milliseconds long, the time slot interval is 50 milliseconds, and a signal dissipation time is reserved) for each parking space, to prevent cross interference of multi-parking space communication signals.

[0053] In step S303, the verification program is executed by the ETC module of the charging pile and the vehicle-mounted ETC module of each parking space according to the communication priority queue.

[0054] In step S304, the verification pass instruction of the cloud management platform is received, the vehicle is started to be charged, the charging data is obtained, and the charging data is sent to the cloud management platform.

[0055] If the verification is passed, the cloud management platform sends a verification pass instruction to the charging pile. The charging control module of the charging pile starts to charge the vehicle. The billing control unit of the charging pile sends the charging information to the charging pile operation platform in real time. The charging data includes but is not limited to the charging power, the consumption amount, etc. If the charging pile operation platform involves peak and valley calculation, the electric power of each time period will also be uploaded.

[0056] The data transmission adopts a combination of periodic and triggered modes. Periodic transmission means sending data to the charging pile operation platform once every certain time (such as 1 minute); event-triggered transmission means sending data to the charging pile operation platform immediately when the charging data changes greatly, such as the charging current suddenly increases or decreases.

[0057] In addition, the charging pile operation platform can also analyze and process the charging information uploaded by the charging pile in real time to monitor the safety and stability of the charging process. If abnormal charging data is found, such as excessive charging current, excessive battery temperature, etc., control instructions are immediately sent to the charging pile to adjust the charging parameters or stop charging.

[0058] Further, the charging pile operation platform can also predict the charging time and remaining power of the vehicle according to the charging data to provide personalized charging services for the vehicle owner.

[0059] Step S305, receiving the stop charging instruction, sending an automatic deduction instruction to the cloud management platform, and completing the deduction operation.

[0060] When the vehicle's power is full or the customer clicks the interface stop charging button, the charging pile stops charging. The charging control module sends the final charging capacity, SOC, charging time, etc. to the charging pile operation platform. The billing module of the charging pile operation platform calculates the charging fee according to the charging capacity and the pre-set billing standard. The charging pile operation platform sends the charging fee information to the ETC settlement center, ready for payment settlement.

[0061] After receiving the charging fee information, the ETC settlement center checks the balance of the ETC account. If the balance is sufficient, the ETC settlement center deducts the fee from the ETC account and feeds back the deduction result to the charging pile operation platform. If the balance is insufficient, the ETC settlement center feeds back the deduction failure information to the charging pile operation platform.

[0062] The charging pile operation platform sends corresponding instructions to the charging pile according to the deduction result. If the deduction is successful, the charging pile operation platform sends a charging settlement completion instruction to the charging pile and sends a charging settlement success notification to the vehicle owner; if the deduction fails, the charging pile operation platform sends a charging settlement failure instruction to the charging pile and sends a charging settlement failure notification to the vehicle owner, prompting the vehicle owner to use other payment methods to pay.

[0063] In some embodiments, receiving the verification failure instruction from the cloud management platform, sending a prompt message to the vehicle-mounted ETC module.

[0064] If the verification failure instruction from the cloud management platform is received, the charging pile sends a prompt message to the user through the vehicle-mounted ETC module (such as displaying through the vehicle central control screen or pushing a short message / notification through the user's mobile phone APP), and the prompt content includes the reason for the verification failure (such as "the vehicle and ETC device binding relationship does not match, please check" etc.).

[0065] It can be seen that in the embodiments of the present application, after the charging pile detects at least two activation signals within a preset time, the charging pile acquires parking space information corresponding to the at least two activation signals and activation times, the activation signals being used to represent a connection state of a charging plug of the charging pile and a vehicle; a communication priority order of each parking space is determined according to the parking space information and the activation times, and a communication time slot of each parking space is allocated, and a communication priority queue is established according to the communication priority order and the communication time slot; the charging pile ETC module and the vehicle-mounted ETC module of each parking space are controlled to perform a verification program according to the communication priority queue; a verification pass instruction from a cloud management platform is received, charging is started, and charging information is recorded; the charging information is sent to the cloud management platform, a fee is calculated; a verification failure instruction from the cloud management platform is received, and prompt information is sent to the vehicle-mounted ETC module. Therefore, by fusing a dynamic time slot allocation algorithm, the present application constructs an ETC non-inductive charging fee collection system in a "vehicle-pile-cloud" cooperative manner, which can effectively solve problems such as signal interference, identity misrecognition, and resource conflict in multi-parking space concurrent charging, ensure the stability and safety of ETC non-inductive payment in a multi-parking space scenario, and at the same time maintain the convenient experience of "plug and charge" of users.

[0066] In some embodiments, the activation time includes a first activation time and a second activation time, the first activation time refers to a time when the charging plug is connected to the vehicle, and the second activation time refers to a time when the charging plug is pulled out of the charging pile; the parking space information includes a parking space number;

[0067] The communication priority order of each parking space is determined according to the parking space information and the activation times, including: judging whether the first activation times of the at least two activation signals are the same; if not, determining the communication priority order of each parking space according to the order of the first activation times; if the same, judging whether the second activation times of the at least two activation signals are the same; if not, determining the communication priority order of each parking space according to the order of the second activation times; if the same, determining the communication priority order of each parking space according to the parking space numbers corresponding to the at least two activation signals.

[0068] For the charging pile, the activation time can be the time when the charging plug is inserted into the vehicle charging port and the physical connection is completed (marking that the vehicle "starts to prepare for charging"), which is accurate to the millisecond level (such as 10:00:00.123), and is recorded as the first activation time. The activation time can also be the time when the charging plug is pulled out of the charging pile socket (marking that the vehicle "enters the state of waiting to be charged"), which is also accurate to the millisecond level (such as 10:00:00.456), and is recorded as the second activation time.

[0069] The parking space information mainly refers to a parking space number, such as a No. 1 parking space and a No. 2 parking space, and each parking space has a unique identifier, which is pre-set by the charging pile.

[0070] In the present application, the communication priority order of multiple parking spaces is determined in a three-level progressive manner to ensure that a unique priority order is generated in any scenario. The specific process is as follows:

[0071] The first level of judgment is based on the first activation time (plug-in time) as the primary basis. When the vehicles of at least two parking spaces are inserted into the charging plug, the first activation time (plug-in time) of the two is compared first. If the first activation time is different, the parking space with the earlier plug-in time has a higher priority (for example, the A parking space is plugged in at 10:00:00.123 and the B parking space is plugged in at 10:00:00.245, so the priority of A is higher than that of B).

[0072] The second level of judgment is based on the second activation time (plug-out time) as the secondary basis. If the first activation time of multiple parking spaces is the same (for example, in an extreme case, two vehicles complete plug-in at the same millisecond, and the time is 10:00:00.123), the second activation time (plug-out time) is further compared. If the second activation time is different, the parking space with the earlier plug-out time has a higher priority (for example, the A parking space is unplugged at 10:00:00.300 and the B parking space is unplugged at 10:00:00.350, so the priority of A is higher than that of B). When the plug-in time is consistent, the behavior of "taking the gun from the charging pile earlier" is used to determine that the vehicle "enters the charging preparation state earlier", and the resources are allocated preferentially.

[0073] The third level of judgment is based on the parking space number as the final basis. If the first activation time and the second activation time of multiple parking spaces are the same in an extreme case (for example, two vehicles plug in at the same time and unplug at the same time), the priority is determined by the inherent order of the parking space number. Usually, it is sorted in the order of "small number to large number" (for example, No. 1 parking space > No. 2 parking space > No. 3 parking space), and the specific rules can be pre-set by the charging pile.

[0074] As can be seen, in the present embodiment, through three-level progressive judgment, a unique priority order can be generated in any multi-parking space concurrent scenario, avoiding communication time slot allocation chaos caused by "priority conflict".

[0075] In some embodiments, the communication time slot includes a time slot length, a time slot interval, and a time slot start time. The time slot length refers to the exclusive communication time of each parking space, for example, fixed at 200 milliseconds (sufficient to complete one ETC signal interaction). The time slot interval refers to the "signal dissipation time" of 50 milliseconds reserved after the end of the time slot of the previous parking space (to avoid interference of residual signals of the previous time slot on the next time slot). The time slot start time is delayed in turn according to the priority order, and the parking space with the highest priority starts communication earliest.

[0076] For example (take 3 parking spaces as an example):

[0077] Parking space No. 1 (priority 1): time slot is 10:00:00.500-10:00:00.700 (start time + 200 milliseconds);

[0078] Parking space No. 3 (priority 2): time slot is 10:00:00.750-10:00:00.950 (start after a 50-millisecond interval from the end of the previous time slot);

[0079] Parking space No. 2 (priority 3): time slot is 10:00:1.000-10:00:1.200 (for the same reason, delayed).

[0080] Further, if strong interference is detected in the time slot of a parking space (such as a signal error rate > 1%), the time slot of the parking space is automatically extended by 50 milliseconds (to ensure complete data reception), and the time slots of subsequent parking spaces are simultaneously shifted backward (such as time slot of parking space No. 2 is delayed to 09:30:01.123-09:30:01.323).

[0081] The three are associated: parking space number, communication priority, and time slot start and end time, to form a structured communication priority queue, which is stored in the local computing unit of the charging pile as the basis for subsequent communication scheduling.

[0082] For example, see Table 1 below, which is an example of a communication priority queue:

[0083]

[0084] As can be seen, in this embodiment, the spatially overlapping signals are separated in the time dimension through "time slicing", which fundamentally solves the problem of cross interference of 5.8 GHz DSRC signals, providing a stable foundation for subsequent verification, charging, and fee deduction processes.

[0085] In some embodiments, the method for obtaining the parking space information includes the following steps: obtaining a first image through a camera corresponding to the charging pile; performing image recognition on the first image to obtain parking space information corresponding to each charging plug of the at least two charging plugs of the charging pile.

[0086] In the scenario of a single charging pile covering multiple parking spaces, each charging plug corresponds to a unique parking space (such as plug No. 1 corresponding to parking space No. 1, and plug No. 2 corresponding to parking space No. 2), but when a vehicle plugs in, the correspondence between the plug and the parking space may be confused (for example, a user takes the gun from plug No. 2 but uses parking space No. 1).

[0087] The parking space information plays an important role in the present application, and specifically, before the vehicle information (such as the vehicle-mounted ETC module information, license plate, VIN code, etc.) is obtained, the parking space number can effectively bind the vehicle and the charging plug, avoiding identity misrecognition, wrong matching of vehicles and accounts, etc. For example, the system obtains the first image of parking space 1 through the camera to identify the number of "parking space 1" (parking space information). Subsequently, when the vehicle-mounted ETC module of parking space 1 sends a response message (containing the license plate and VIN code), the system can directly associate "the vehicle information in the response message" with "parking space 1" to form a complete link of "parking space 1-vehicle A-ETC account A". If there is no parking space information obtained in advance, even if the vehicle information is identified later, it is still impossible to determine "which charging demand of the vehicle corresponds to the parking space", and a serious error may occur, such as "vehicle A charges in parking space 1, but the ETC fee of vehicle B is deducted", which violates the core goal of "accurate fee deduction" of the automatic toll collection system.

[0088] In addition, the parking space information is the key to mapping the "time slot and parking space": the system first determines "which parking space to allocate the time slot to" according to the "communication priority queue" (which has been sorted in combination with the parking space information); then binds the allocated "time slot" with the "parking space number" (such as "priority 1→ parking space 1→ time slot 1", "priority 2→ parking space 2→ time slot 2"); and subsequently, the charging pile ETC module only communicates with the vehicle-mounted ETC module of the parking space within the "corresponding time slot". Without parking space information, the system cannot determine "which parking space the allocated time slot corresponds to", and the time slot allocation will become "blind", and the communication conflict problem cannot be solved.

[0089] Therefore, it is necessary to accurately obtain the parking space information.

[0090] In the present application, the camera deployed at the charging pile collects the on-site image, automatically analyzes the spatial position relationship between the charging plug and the parking space through image recognition technology, accurately matches the corresponding relationship of "charging plug-parking space number", and ensures that the obtained parking space information is real and accurate, providing a reliable basis for subsequent communication scheduling.

[0091] In a specific implementation, a high-definition camera (resolution not less than 1080P) can be installed on the top or side of the charging pile, and the lens viewing angle covers all parking spaces and corresponding charging plugs (e.g., 2-4 parking spaces panoramic), ensuring that the position of the charging plug, the cable direction, and the parking area of the vehicle can be clearly captured. When the charging pile detects that any charging plug is pulled out (triggering the second activation time) or inserted into a vehicle (triggering the first activation time), the camera immediately captures the first image; if multiple activation signals are detected (multiple parking spaces concurrent), 2-3 images are continuously captured within a preset time (e.g., within 1 second), and the one with the highest clarity is taken as the first image. The first image must contain the following key information: the physical location of each charging plug (e.g., plug 1 hanging on the charging pile, plug 2 pulled out), the connection relationship between the plug cable and the parking space (e.g., the cable of plug 2 extends to parking space 3), and the parking area of the vehicle (e.g., the vehicle body is located within the 1st parking line).

[0092] Next, a target detection algorithm based on deep learning (e.g., YOLO, Faster R-CNN) is used to identify key targets from the first image: charging plug: mark the unique identification of each plug (e.g., distinguish plug 1 and plug 2 through the two-dimensional code, color coding, or shape features on the plug surface); parking area: identify the parking lines on the ground and the parking number identification (e.g., "1" and "2" numbers sprayed on the ground); cable and vehicle: identify the direction of the plug cable (e.g., extending from plug 2 to parking space 3) and the relative position of the vehicle body and the parking line (e.g., the vehicle body is completely within the 3rd parking line).

[0093] Through spatial position relationship analysis, the corresponding relationship between "charging plug-parking space" is established: if the plug has been inserted into the vehicle: determine the target parking area where the vehicle body is located (e.g., the vehicle is within the 1st parking line), then the plug corresponds to the target parking space (e.g., the 1st parking space); if the plug has been pulled out but not inserted into the gun: match the corresponding parking number according to the extension direction of the cable (e.g., the plug is dragged to the 2nd parking area); if the plug has not been pulled out (idle state): directly associate it with its default corresponding parking space (e.g., plug 1 corresponds to the 1st parking space).

[0094] Finally, the recognition result is converted into structured parking information, such as "1st charging plug corresponds to 1st parking space" and "2nd charging plug corresponds to 3rd parking space", and stored in the local database of the charging pile as the basis for subsequent priority judgment.

[0095] As can be seen, in this embodiment, compared to the traditional "plug number fixed corresponding parking space" static binding method (which may cause errors due to users using plugs across parking spaces), image recognition through dynamic analysis of spatial relationships can significantly reduce the error rate of parking information and is not affected by user usage habits (such as taking the gun across the parking space, dragging the cable), and can automatically adapt to various non-standard operation scenarios.

[0096] In some embodiments, the verification program includes a vehicle-side verification program and a non-vehicle-side verification program, the vehicle-side verification program is used to screen a target vehicle-mounted ETC module in communication with the charging pile ETC module; the non-vehicle-side verification program is used to verify the binding relationship between the vehicle and the target vehicle-mounted ETC module, and the validity of the ETC account of the vehicle.

[0097] In some embodiments, the vehicle-side verification program includes the following steps:

[0098] sending a first verification message to the vehicle through the charging plug, the first verification message including a first charging pile number corresponding to the vehicle and a first parking space number; in a single communication time slot, sending an inquiry message to each vehicle-mounted ETC module corresponding to the parking space through the charging pile ETC module, the inquiry message including a second charging pile number and a second parking space number, the inquiry message being used to instruct the target vehicle-mounted ETC module to send a response message to the charging pile ETC module, the target vehicle-mounted ETC module being a vehicle-mounted ETC module with the same second charging pile number and first charging pile number and the same second parking space number and first parking space number, the response message including at least one of an account ID, a vehicle VIN code, a license plate, and a vehicle-mounted ETC module device number; and receiving the response message from the target vehicle-mounted ETC module.

[0099] When the charging plug is inserted into the vehicle, the charging pile sends a first verification message to the vehicle through the physical line of the charging plug, the content including: a first charging pile number (such as "Pile-001", uniquely identifying the current charging pile); a first parking space number (such as "No. 1 parking space", identifying the specific parking space where the vehicle is located), so that the vehicle knows which charging pile and which parking space it is connected to, preparing for subsequent response verification.

[0100] Secondly, according to the preset communication priority queue, the charging pile broadcasts an inquiry message to all vehicle-mounted ETC modules in the exclusive communication time slot of the current parking space (such as 10:00:00.500-0.700 for the time slot of No. 1 parking space), the content including:

[0101] a second charging pile number (consistent with the first charging pile number, such as "Pile-001");

[0102] a second parking space number (consistent with the first parking space number, such as "No. 1 parking space").

[0103] Therefore, although the inquiry message is "broadcasted", it contains a clear "charging pile + parking space" identifier, and only the vehicle-mounted ETC module that meets the conditions will respond.

[0104] Thirdly, the vehicle's on-board ETC module receives the inquiry message and automatically compares the information stored therein. If the "second charging pile number" received by the on-board ETC module is consistent with the "first charging pile number" obtained by the vehicle from the charging plug, and the "second parking space number" is consistent with the "first parking space number" (i.e., the "pile-001 + No. 1 parking space" matches), it is determined that the "target on-board ETC module" is the on-board ETC module of the vehicle parked in the No. 1 parking space.

[0105] Finally, the target on-board ETC module sends a response message to the charging pile ETC module, including account ID, vehicle VIN code, license plate, on-board ETC module device number, and other core information.

[0106] As can be seen, in the embodiment, the "number two-way matching" is used to accurately lock the on-board ETC module of the current parking space, and to exclude the interference of other parking space devices (e.g., the on-board ETC module of the No. 2 parking space does not respond due to number mismatch). The charging pile ETC module only receives the response message of the target on-board ETC module in the exclusive time slot, ignores other irrelevant signals, and completes the screening process of the vehicle-end verification.

[0107] In some embodiments, the non-vehicle-end verification procedure includes a pile-end verification procedure and a cloud-end verification procedure, and the non-vehicle-end verification procedure includes the following steps:

[0108] The pile-end verification procedure is performed on the response message, and the pile-end verification procedure is used to check the data integrity of the response message. If the data is complete, a verification request is sent to the cloud-end management platform, and the verification request includes the response message. The verification request is used to instruct the cloud-end management platform to perform the cloud-end verification procedure. If the data is incomplete, a data supplement request is sent to the on-board ETC module.

[0109] The non-vehicle-end verification procedure is a deep verification completed by the charging pile (pile-end) and the cloud-end management platform (cloud-end) after the target on-board ETC module is screened out by the vehicle-end verification. The core goal is to ensure that the response message data sent by the vehicle-end is complete and has not been tampered with (the pile-end verification is responsible for this), and to confirm that the binding relationship between the vehicle and the ETC device is legal and the ETC account status is normal (the cloud-end verification is responsible for this). The two form a progressive relationship of "first local verification and then global audit": the pile-end verification is responsible for the reliability of data transmission, and the cloud-end verification is responsible for the security of the account and the binding relationship, which together avoids the charging risk caused by incomplete data and abnormal accounts.

[0110] For the pile-end verification procedure, when the charging pile receives the response message (including account ID, VIN code, license plate, etc.) of the target on-board ETC module, the pile-end verification procedure is first started, and the core action is data integrity check. The specific way includes:

[0111] Format check: Check if the response message conforms to the preset data format (such as whether the number of fields is complete, the length of each field is compliant, for example, the VIN code must be 17 characters, and the license plate must comply with the "province abbreviation + letter + 5-digit / letter" rule);

[0112] Checksum verification: Compare the checksum in the response message with the checksum calculated locally by the charging pile through CRC (Cyclic Redundancy Check) or hash algorithm (such as MD5) to determine whether the data has been tampered with or lost during transmission;

[0113] Non-empty check of key fields: Ensure that core fields such as account ID and vehicle-mounted ETC module device number are not empty (these fields are necessary conditions for subsequent cloud verification).

[0114] For example, if the "account ID" field is missing in the response message, or the VIN code is only 16 characters (not conforming to the format), the pile-end verification determines that the data is incomplete.

[0115] Among them, after the pile-end verification, two results will be produced, corresponding to different processing procedures:

[0116] (1) Data is complete: Send verification request to cloud

[0117] If the response message passes the integrity check, the charging pile will package the response message as a verification request (with additional metadata such as charging pile number, parking space number, and current timestamp) and send it to the cloud management platform through an encrypted communication link (such as TLS 1.3 protocol) to request the start of the cloud verification program. After the preliminary screening of "data eligibility" is completed by the pile-end, the verification authority is transferred to the cloud, and the global data of the cloud (such as ETC account status, binding relationship library) is used for more in-depth security check.

[0118] (2) Data is incomplete: Send data supplement request to vehicle-mounted ETC module

[0119] If the response message does not pass the integrity check (such as missing fields, format errors, or checksum mismatch), the charging pile does not directly determine that the verification fails, but sends a data supplement request to the target vehicle-mounted ETC module, clearly requesting to supplement the missing or incorrect fields (for example, "please supplement the account ID field" "VIN code format error, please resend").

[0120] Among them, the supplement request only requires the return of abnormal fields (not the complete message), reducing the amount of communication data; if it still does not meet the requirements after 2 consecutive supplements (such as vehicle-mounted ETC module failure causing incorrect sending), the pile-end determines that the verification fails, terminates the process and prompts the user to check the equipment.

[0121] It can be seen that in the present embodiment, the wireless communication between the vehicle end and the pile end may be affected by electromagnetic interference, too far distance, etc., resulting in data loss or tampering. The pile end can verify the problem in time by passing the integrity check, avoid the subsequent audit error caused by the incomplete data transmission into the cloud (such as unable to query the ETC information due to the missing account ID), reduce the invalid cloud verification request, make the cloud resources concentrate on processing effective data, and improve the overall efficiency of the system.

[0122] In some embodiments, the cloud verification procedure comprises the following steps:

[0123] According to the account ID, the vehicle VIN code, and at least one of the license plate, the ETC account information is queried, the ETC account information including at least one of the account state, the bound vehicle-mounted ETC module device number; if the account state is in the active state, and the bound vehicle-mounted ETC module device number is consistent with the vehicle-mounted ETC module device number in the response message, it is determined that the verification result of the verification procedure is verified; if the account state is in the non-active state, or the bound vehicle-mounted ETC module device number is inconsistent with the vehicle-mounted ETC module device number in the response message, it is determined that the verification result is not verified.

[0124] The cloud verification procedure is a deep security check performed by the cloud management platform after the pile end verification passes (data integrity). The core goal is to confirm that the user's ETC account is in a normal and available state (not frozen, not lost), and to verify that the current communication vehicle-mounted ETC module and the account have a legal binding relationship (to prevent device theft).

[0125] First, after the cloud management platform receives the verification request (including the response message) sent by the pile end, it first locates the user's ETC account according to at least one of the account ID, the vehicle VIN code, or the license plate. Through multi-dimensional query, even if some information is missing or incorrect (such as account ID transmission anomaly), the account can still be located through the VIN code or license plate, improving the query fault tolerance. The ETC account information obtained after the query includes at least:

[0126] Account state: including active (normal use) state, non-active (not enabled) state, frozen (restricted due to violation) state, loss (device loss report) state, etc.

[0127] Bound vehicle-mounted ETC module device number: the unique device number (such as "OBU-7890") registered by the account in the ETC system, forming a strong binding relationship of "account-device-vehicle" with the vehicle.

[0128] Secondly, the cloud management platform compares the ETC account information queried with the data in the response message, and performs the following double verification:

[0129] (1) Account state verification: Determine whether the account state is "active state": If it is active state: meet the first verification condition; if it is not active, frozen or lost state: directly determine "verification failed" (for example, the lost account may have the risk of stolen device, the frozen account may have the unsettled fee);

[0130] (2) Device binding relationship verification: Compare "cloud-stored binding device number" with "vehicle-mounted ETC module device number in response message": if they are completely consistent, then meet the second verification condition; if they are not consistent, then determine "verification failed" (may be stolen from others or device tampering).

[0131] Finally, when both conditions of "account state is active" and "device number is consistent" are met, the cloud sends "verification passed + allow charging" instruction to the charging pile, authorizing the start of the charging process. If any one of the conditions is not met (such as account frozen, or device number does not match), the cloud sends "verification failed" instruction to the charging pile, with the failure reason (such as "account has been lost" "device and account do not match"), and the charging pile pushes the corresponding prompt to the user.

[0132] As can be seen, in the embodiment, through the double verification of account state and device binding relationship, the legality and safety of ETC charging are ensured from the global level.

[0133] The present application has the following technical effects:

[0134] 1. Convenience

[0135] The car owner does not need to use cash, bank card or mobile phone scan code payment method, only needs to insert the charging plug into the vehicle, which can automatically complete the charging and payment process, and the operation is simple and convenient.

[0136] 2. Efficiency

[0137] The automatic processing and real-time data transmission function of the system greatly shortens the charging payment time and improves the charging efficiency.

[0138] 3. Safety

[0140] 4. Management

[0141] The charging pile operation platform can remotely manage and monitor the charging equipment, timely find and solve problems, and improve the maintenance efficiency and management level of the equipment.

[0144] In the case of using an integrated unit, please refer to Figure 4 , Figure 4 A functional unit structure block diagram of an automatic charging device based on the combination of a charging pile and ETC is provided for the embodiments of the present application.
