Description

Technical Field

[0001] This invention relates to the field of charging pile allocation technology, and in particular to a method for information exchange among charging pile groups. Background Technology

[0002] With the development of the Internet of Things (IoT), an important branch of mobile communication, low-cost device sensing and communication access have become possible. Developing IoT smart charging piles, endowing charging pile clusters with control capabilities, and keeping pace with the development trends of the energy revolution and digital revolution, will enable the smart charging pile infrastructure, network integration, and business innovation that integrates wattage and data flow. One of the key technologies that this project aims to solve is to develop smarter and more efficient charging piles through technological integration.

[0003] The varying locations of different charging piles within existing charging stations result in significant differences in charging power within the same timeframe. Furthermore, the diverse designs and technologies of new energy vehicles lead to underutilization of charging station power. Specific examples include: 1. Some high-power charging piles are being used by batteries charging with lower power, forcing electric vehicles capable of high-power charging to use lower-power piles, resulting in resource waste; 2. Some high-power charging piles are occupied by unused piles. While electric vehicle users could park in nearby spaces and run the charging cable, the charging locations vary by model, and users cannot know in advance where charging is available.

[0036] To fully understand this invention, a detailed structure will be presented in the following description to illustrate the technical solution proposed by this invention. Optional embodiments of the invention are described in detail below; however, in addition to these detailed descriptions, the invention may have other embodiments.

[0037] See Figure 1 The first aspect of this invention discloses a method for information interaction among charging pile groups, the method comprising the following steps:

[0038] S1. Obtain basic information about the charging pile and establish an initial scene model based on the basic information about the charging pile. The basic information about the charging pile includes the charging pile number, the location of the charging pile, the parking space number corresponding to the charging pile, and the length of the charging cable.

[0039] S2. Obtain basic vehicle information, including license plate number, charging method, maximum charging power and vehicle model information;

[0040] S3. Obtain the theoretical charging power of each available charging pile, compare it with the vehicle's maximum charging power, and determine the preferred charging pile number.

[0041] S4. Obtain point cloud data uploaded by visual sensors installed between charging pile groups and parking space sensors on parking spaces, update the scene with the point cloud data and the initial scene model to obtain the Nth intermediate scene model.

[0042] S5. Randomly select an available parking space number and vehicle basic information and input them into the Nth intermediate scenario model. If the available parking space number meets the requirements, send the available parking space number and the corresponding charging pile number to the user. If the available parking space number does not meet the requirements, select a new available parking space number and vehicle basic information and input them into the Nth intermediate scenario model for repeated judgment.

[0043] Specifically, this invention first acquires information about vehicles entering the station. Based on vehicle model information, it downloads the maximum supported charging power and charging location of the vehicle from the database. A power detection module detects the output power of the charging pile group and the charging power of each charging pile in the station, calculating the optimal charging pile for the vehicle model and outputting several optimal charging pile numbers. A scene model is established to simulate the environment of each charging pile group. Sensors acquire the locations of occupied charging piles. The vehicle model's charging location is then fused into the scene model to obtain the optimal parking space number. This optimal parking space number and the corresponding charging pile number are sent to the mobile terminal. The user connects to the corresponding charging pile on the mobile terminal based on the parking space number they reach. Although the parking space number and charging pile number sent to the mobile terminal may differ, it ensures that the user's vehicle model can connect to the optimal parking space number and charging pile. The charging pile power meets the user's maximum power requirements, and the charging pile group can reserve high-power charging piles for high-power charging vehicle models, maximizing the total charging time for all vehicle models and ensuring maximum utilization of charging pile resources.

[0044] Specifically, in step S1, basic vehicle information is obtained, including:

[0045] Before entering the charging station, users use their mobile devices to scan the QR code in front of the charging station to log in to the station server and input basic vehicle information into the station server. The basic vehicle information input by the user includes license plate number, charging method, maximum charging power and vehicle model information.

[0046] Obtain the vehicle's basic information from the site server.

[0047] Specifically, the theoretical charging power of each available charging station is obtained and compared with the vehicle's maximum charging power to determine the preferred charging station number. This includes:

[0048] Upload vehicle model data to the database, and download the theoretical charging method and theoretical maximum charging power corresponding to the vehicle data and configuration data from the database.

[0049] Based on the theoretical charging power of the charging pile, the optimal charging pile number and location are obtained by comparing it with the vehicle's theoretical charging method and theoretical maximum charging power.

[0050] Specifically, a spare parking space number and basic vehicle information are randomly selected and input into the Nth intermediate scene model. This includes determining the parking space location in the Nth intermediate scene model based on the spare parking space number, and generating a simulated vehicle at the parking space location in the Nth intermediate scene model based on the basic vehicle information.

[0051] Specifically, the required conditions include: taking the location of the vacant parking space as the center, and judging whether the preferred charging pile can reach the location of the vacant parking space based on the length of the preferred charging pile's charging cable.

[0052] Specifically, the method is applied to an information exchange system among charging pile groups. This system establishes data exchange channels with a site server, a mobile terminal, and a transportation system. The system includes an acquisition module, a scene creation module, a fusion module, a judgment module, a power detection module, a database module, and a communication module.

[0053] The acquisition module is used to acquire vehicle information from the site server. The vehicle information includes license plate number, charging method, maximum charging power and vehicle model information.

[0054] The scene establishment module is used to establish a preset scene model based on the charging station parking space, charging pile location, and charging cable length, and transmit the data to the fusion module for scene fusion.

[0055] The fusion module is used to perform simulated scene fusion on the original scene model and vehicle data, identify it as an intermediate scene model, add parking space numbers, and then perform scene fusion again.

[0056] The judgment module is used to match and judge the intermediate scene model and the parking space number, and output the preferred parking space number;

[0057] The power detection module is used to detect the charging power of each charging pile in the power station and calculate the maximum theoretical power of the charging pile to be used.

[0058] The database module is used to store vehicle model data and the corresponding charging type, maximum charging power, charging location, and charging entry / exit method.

[0059] The communication module is used for signal transmission between the site server, the transportation system, and the mobile terminal.

[0060] The invention first acquires information about vehicles entering the station. After receiving the vehicle's license plate information, the station server retrieves the vehicle model and configuration data corresponding to that license plate from the traffic system. Based on the vehicle model information, it downloads the maximum supported charging power and charging location of the vehicle from the database. A power detection module detects the output power of the charging pile group and the charging power of each charging pile in the station, calculating the optimal charging pile for that vehicle model and outputting several optimal charging pile numbers. Through scene model establishment, a preset scene model is pre-built based on the charging station parking spaces, charging pile locations, and charging cable lengths. Point cloud data uploaded by visual sensors installed between the charging pile group and parking space sensors are fused with the preset scene model to obtain the Nth original scene model. When acquiring the Nth vehicle data under the Nth original scene model, scene fusion is performed on the Nth original scene model based on the vehicle model, charging location, and charging entry / exit method in the vehicle data to obtain the Nth intermediate scene model. The parking space number M is then fused into the Nth intermediate scene model; the parking space number M is then obtained. The simulated location information of the charging position of vehicle N at parking space M is used to output parking space M and its corresponding charging pile number S when the following conditions are met: A. There is no vehicle parking data in parking space M within the Nth original scene model; B. The preferred charging pile number S can radiate to the location centered on the simulated location information of vehicle N. If the above conditions are not met, parking space M is incremented by 1, and the above judgment process continues until all preferred parking space numbers are obtained. The preferred parking space numbers and their corresponding charging pile numbers are then sent to the mobile terminal. That is, the user connects to the corresponding charging pile on the mobile terminal based on the parking space number reached by the mobile terminal. Although the parking space number and charging pile number sent to the mobile terminal are inconsistent, it can be guaranteed that the user's vehicle model can connect to the preferred parking space number and charging pile. The power of the charging pile meets the user's maximum power requirement, and the charging pile group can reserve high-power charging piles for high-power charging vehicle models, maximizing the total charging time of all vehicle models to the minimum, that is, maximizing the utilization of charging pile resources.

[0061] The present invention also discloses a computer device, including a memory and a processor, wherein the memory is used to store a computer program, and the processor runs the computer program to enable the computer device to perform the information interaction method between charging pile groups.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
