Description

Technical Field

[0001] This application relates to the field of charging piles, and in particular to an intelligent scheduling method and device for charging piles based on the Internet of Things. Background Technology

[0002] With the rise of the new energy industry, electric vehicles are becoming increasingly popular. This raises two issues: first, the demand for charging stations is increasing; second, the demand for parking spaces is also increasing. These issues can be addressed by increasing the number of charging stations and parking spaces, respectively, but this approach significantly increases costs and is not the optimal solution.

[0003] In one preferred solution, to address the parking space requirement, a multi-level parking system can be constructed. This involves building a structure that allows vehicles to be parked in non-contact, layered spaces instead of traditional flat parking spaces, thereby improving space utilization.

[0004] While this preferred solution addresses the second problem, it fails to address the first problem of increased demand for charging stations. Therefore, existing technologies lack suitable solutions to meet the demand for charging stations at a lower cost. Summary of the Invention

[0005] This application proposes an intelligent scheduling method for charging piles based on the Internet of Things. The charging piles are located in a multi-level parking space, and include multiple fixed charging piles and multiple mobile charging piles with different heights. The multi-level parking space includes multiple suspended platforms for parking electric vehicles and transportation equipment for transporting electric vehicles. Multiple fixed charging piles are located in the center of the multi-level parking space, and each fixed charging pile corresponds to a suspended platform. The height of the highest fixed charging pile is less than that of the highest suspended platform. Each suspended platform is equipped with a sensor to detect whether an electric vehicle is parked there.

[0006] The intelligent scheduling method for charging piles includes:

[0007] S1: Obtain parking requests sent by multiple electric vehicle terminals through the Internet of Things; each parking request includes the expected driving trajectory, parking time, and current battery level of each electric vehicle terminal.

[0008] S2: Based on the preset charging necessity judgment method, and taking into account the expected driving trajectory, parking time and current battery level, determine whether the electric vehicles corresponding to multiple electric vehicle terminals need to be charged.

[0009] S3: Sort electric vehicles that need charging to the bottom and electric vehicles that do not need charging to the top, thereby generating an electric vehicle sorting table.

[0010] S4: Receive sensor signals from sensors installed on each suspended platform via the Internet of Things, and generate a list of vacant suspended platforms based on the sensor signals.

[0011] S5: Based on the electric vehicle sorting list and the list of vacant suspended platforms, use the pre-set transport equipment to transport multiple electric vehicles to the suspended platforms of the multi-level parking space; among them, vehicles ranked lower in the electric vehicle sorting list are transported to vacant suspended platforms with a lower height.

[0012] S6: Obtain the specified height value of the highest fixed charging pile, generate a list of mobile charging vehicles based on the specified height value, and determine whether the list of mobile charging vehicles is empty; among them, the electric vehicles in the list of mobile charging vehicles have a common feature: the height value of the suspended platform on which they are parked is greater than the specified height value.

[0013] S7: If empty, generate a fixed charging instruction to instruct that electric vehicles that need charging should only be charged via fixed charging stations;

[0014] S8: If not empty, generate a comprehensive charging instruction to instruct fixed charging of electric vehicles that need charging through fixed charging piles, and simultaneously dispatch multiple mobile charging piles to provide mobile charging for electric vehicles in the mobile charging vehicle list.

[0015] Further, step S2, which determines whether the electric vehicles corresponding to multiple electric vehicle terminals have a charging necessity based on the expected driving trajectory, parking time, and current battery level according to a preset charging necessity judgment method, includes:

[0016] S201: Extract the corresponding expected driving trajectory, parking time, and current battery level from the designated parking application corresponding to the designated electric vehicle terminal;

[0017] S202: Determine whether the parking time exceeds the preset duration and whether the current battery level exceeds the preset battery threshold;

[0018] S203: If the parking time is longer than the preset duration and the current battery level is not greater than the preset battery level threshold, the estimated driving mileage will be calculated based on the expected driving trajectory.

[0019] S204: Determine whether the current battery level is sufficient to support the estimated driving range;

[0020] S205: If the current battery level is insufficient to support the estimated driving range, the estimated parking location and parking time are extracted from the estimated driving trajectory, and the density of the first available charging piles corresponding to the estimated parking location is extracted from the preset electronic map; wherein, the location and status of the charging piles are marked on the electronic map.

[0021] S206: Obtain the density of the second available charging piles corresponding to the three-dimensional parking space, and determine whether the density of the first available charging piles is greater than the density of the second available charging piles;

[0022] S207: If it is not greater than, then it is determined that the electric vehicle corresponding to the specified electric vehicle terminal needs to be charged.

[0023] Furthermore, the multiple fixed charging piles include at least some wireless charging piles, and one wireless charging pile can charge at least two electric vehicles located on adjacent suspended platforms; the step S5, which involves transporting multiple electric vehicles to the suspended platforms of the multi-level parking space using a preset transport device according to the electric vehicle sorting table and the list of vacant suspended platforms, includes:

[0024] S501: Based on the standard of whether wireless charging is possible, electric vehicles that need to be charged in the electric vehicle ranking list are clustered to generate a first cluster and a second cluster; wherein, the first cluster includes electric vehicles that can be wirelessly charged, and the second cluster includes electric vehicles that cannot be wirelessly charged.

[0025] S502: Based on the electric vehicle sorting list and the list of vacant suspended platforms, using a preset transport device, the electric vehicle ranked first in the electric vehicle sorting list is transported to the highest vacant suspended platform, then the electric vehicle ranked second first in the electric vehicle sorting list is transported to the second highest vacant suspended platform, and so on, until all electric vehicles in the electric vehicle sorting list that do not require charging are transported to the vacant suspended platforms.

[0026] S503: Based on the electric vehicle sorting table and the list of vacant suspended platforms, use the preset transport equipment to transport electric vehicles belonging to the first cluster to the suspended platform equipped with wireless charging piles; transport electric vehicles belonging to the second cluster to the suspended platform equipped with other fixed charging piles.

[0027] Furthermore, the minimum movable height of multiple mobile charging piles is greater than the height of the highest fixed charging pile.

[0028] Furthermore, multiple mobile charging stations are configured to be dispatchable throughout the entire multi-level parking space; after step S7, which generates a fixed charging instruction to instruct electric vehicles requiring charging to be fixedly charged only through fixed charging stations if the current location is empty, the process includes:

[0029] S71: Receives fault signals sent by designated fixed charging piles via the Internet of Things;

[0030] S72: Dispatch an idle mobile charging station to descend to the designated fixed charging station and replace the designated fixed charging station to charge the corresponding electric vehicle.

[0031] This invention provides an IoT-based intelligent scheduling device for charging piles. The charging piles are located within a multi-level parking space, and include multiple fixed charging piles and multiple mobile charging piles of varying heights. The multi-level parking space includes multiple suspended platforms for parking electric vehicles and transport equipment for transporting electric vehicles. Multiple fixed charging piles are located in the center of the multi-level parking space, and each fixed charging pile corresponds to a suspended platform. The height of the highest fixed charging pile is less than that of the highest suspended platform. Each suspended platform is equipped with a sensor to detect whether an electric vehicle is parked there.

[0032] The intelligent scheduling device for charging piles includes:

[0033] The parking application acquisition module is used to acquire parking applications sent by multiple electric vehicle terminals via the Internet of Things. Each parking application includes the expected driving trajectory, parking time, and current battery level of each electric vehicle terminal.

[0034] The first judgment module is used to determine whether the electric vehicles corresponding to multiple electric vehicle terminals need to be charged based on the expected driving trajectory, parking time and current battery level, according to the preset charging necessity judgment method.

[0035] The electric vehicle sorting table generation module is used to sort electric vehicles that need charging later and electric vehicles that do not need charging earlier, thereby generating an electric vehicle sorting table.

[0036] The platform list generation module is used to receive sensing signals from sensors set on various suspended platforms via the Internet of Things, and generate a list of vacant suspended platforms based on the sensing signals.

[0037] The transport module is used to transport multiple electric vehicles to the suspended platforms of the multi-level parking space using preset transport equipment, based on the electric vehicle sorting list and the list of vacant suspended platforms; among them, vehicles ranked later in the electric vehicle sorting list are transported to vacant suspended platforms with a lower height.

[0038] The second judgment module is used to obtain the specified height value of the highest fixed charging pile, generate a list of mobile charging vehicles based on the specified height value, and determine whether the list of mobile charging vehicles is empty; among them, the electric vehicles in the list of mobile charging vehicles have a common feature: the height value of the suspended platform on which they are parked is greater than the specified height value.

[0039] A fixed charging module, if empty, generates a fixed charging instruction to instruct that electric vehicles that need charging should only be charged via fixed charging stations.

[0040] The integrated charging module, if not empty, generates an integrated charging instruction to instruct fixed charging of electric vehicles that need charging through fixed charging piles, and simultaneously dispatches multiple mobile charging piles to provide mobile charging for electric vehicles in the mobile charging vehicle list.

[0041] Furthermore, the step of determining whether the electric vehicles corresponding to multiple electric vehicle terminals need charging based on a preset charging necessity judgment method, using the expected driving trajectory, parking time, and current battery level as criteria, includes:

[0042] Extract the corresponding estimated driving trajectory, parking time, and current battery level from the designated parking application corresponding to the designated electric vehicle terminal;

[0043] Determine whether the parking time exceeds the preset duration and whether the current battery level exceeds the preset battery threshold;

[0044] If the parking time exceeds the preset duration and the current battery level is not greater than the preset battery level threshold, the estimated driving mileage will be calculated based on the expected driving trajectory.

[0045] Determine if the current battery level is sufficient to support the estimated driving range;

[0046] If the current battery level is insufficient to support the estimated driving range, the estimated parking location and parking time are extracted from the estimated driving trajectory, and the density of the first available charging piles corresponding to the estimated parking location is extracted from the preset electronic map; the location and status of the charging piles are marked on the electronic map.

[0047] Obtain the density of the second available charging piles corresponding to the three-dimensional parking space, and determine whether the density of the first available charging piles is greater than the density of the second available charging piles;

[0048] If the value is not greater than the specified value, then the electric vehicle corresponding to the specified electric vehicle terminal is determined to have a need for charging.

[0049] Furthermore, the multiple fixed charging piles include at least some wireless charging piles, and one wireless charging pile can charge at least two electric vehicles located on adjacent suspended platforms; the step of transporting multiple electric vehicles to the suspended platforms of the multi-level parking space using a preset transport device according to the electric vehicle sorting table and the list of vacant suspended platforms includes:

[0050] Based on the criteria of whether wireless charging is possible, electric vehicles that require charging are clustered in the electric vehicle ranking list to generate a first cluster and a second cluster; wherein, the first cluster includes electric vehicles that can be wirelessly charged, and the second cluster includes electric vehicles that cannot be wirelessly charged.

[0051] Based on the electric vehicle ranking list and the list of vacant suspended platforms, a pre-set transport device is used to transport the electric vehicle ranked first in the electric vehicle ranking list to the highest vacant suspended platform, then the electric vehicle ranked second first in the electric vehicle ranking list to the second highest vacant suspended platform, and so on, until all electric vehicles in the electric vehicle ranking list that do not require charging are transported to the vacant suspended platforms.

[0052] Based on the electric vehicle sorting table and the list of vacant suspended platforms, electric vehicles belonging to the first cluster are transported to suspended platforms equipped with wireless charging piles using pre-set transport equipment; electric vehicles belonging to the second cluster are transported to suspended platforms equipped with other fixed charging piles.

[0053] Furthermore, the minimum movable height of multiple mobile charging piles is greater than the height of the highest fixed charging pile.

[0054] Furthermore, multiple mobile charging stations are configured to be dispatchable throughout the entire multi-level parking space; if empty, a fixed charging instruction is generated to instruct that electric vehicles requiring charging be charged only via fixed charging stations, including:

[0055] Receive fault signals sent by designated fixed charging piles via the Internet of Things;

[0056] The idle mobile charging pile is dispatched to descend to the designated fixed charging pile and replaces the designated fixed charging pile to charge the corresponding electric vehicle.

[0057] This application discloses an IoT-based intelligent scheduling method and apparatus for charging piles. It acquires parking requests from multiple electric vehicle terminals; determines whether the electric vehicles corresponding to these terminals require charging; generates an electric vehicle sorting table; generates a list of vacant suspended platforms; transports the multiple electric vehicles to the suspended platforms of a multi-level parking space; generates a list of mobile charging vehicles; and generates fixed charging instructions or comprehensive charging instructions. Thus, in a multi-level parking space, and by utilizing multiple fixed charging piles of varying heights and multiple mobile charging piles, it is possible to meet the charging needs of electric vehicles with a relatively small number of charging piles deployed.

[0069] Reference Figure 1 and Figure 4This application provides an intelligent scheduling method for charging piles based on the Internet of Things. The charging piles are located in a multi-level parking space and include multiple fixed charging piles 1 and multiple mobile charging piles 3 of different heights. Figure 4 Only one is shown in the diagram, but there are actually multiple ones. Since the location of the mobile charging station is not fixed, it can appear at any desired location in the multi-level parking space and can move horizontally or vertically. The multi-level parking space includes multiple suspended platforms 2 for parking electric vehicles and transport equipment for transporting electric vehicles (not shown, and its location may also be variable). Multiple fixed charging stations 1 are located in the center of the multi-level parking space, each fixed charging station 1 corresponding to a suspended platform 2. The height of the highest fixed charging station 1 is less than the height of the highest suspended platform 2 (e.g., ...). Figure 4 This indicates that not all suspended platforms 2 are equipped with fixed charging piles 1, and suspended platforms 2 without fixed charging piles 1 are located in the upper space; each suspended platform 2 is equipped with a sensor (not shown) to sense whether an electric vehicle is parked there.

[0070] The intelligent scheduling method for charging piles includes:

[0071] S1: Obtain parking requests sent by multiple electric vehicle terminals through the Internet of Things; each parking request includes the expected driving trajectory, parking time, and current battery level of each electric vehicle terminal.

[0072] S2: Based on the preset charging necessity judgment method, and taking into account the expected driving trajectory, parking time and current battery level, determine whether the electric vehicles corresponding to multiple electric vehicle terminals need to be charged.

[0073] S3: Sort electric vehicles that need charging to the bottom and electric vehicles that do not need charging to the top, thereby generating an electric vehicle sorting table.

[0074] S4: Receive sensor signals from sensors installed on each suspended platform via the Internet of Things, and generate a list of vacant suspended platforms based on the sensor signals.

[0075] S5: Based on the electric vehicle sorting list and the list of vacant suspended platforms, use the pre-set transport equipment to transport multiple electric vehicles to the suspended platforms of the multi-level parking space; among them, vehicles ranked lower in the electric vehicle sorting list are transported to vacant suspended platforms with a lower height.

[0076] S6: Obtain the specified height value of the highest fixed charging pile, generate a list of mobile charging vehicles based on the specified height value, and determine whether the list of mobile charging vehicles is empty; among them, the electric vehicles in the list of mobile charging vehicles have a common feature: the height value of the suspended platform on which they are parked is greater than the specified height value.

[0077] S7: If empty, generate a fixed charging instruction to instruct that electric vehicles that need charging should only be charged via fixed charging stations;

[0078] S8: If not empty, generate a comprehensive charging instruction to instruct fixed charging of electric vehicles that need charging through fixed charging piles, and simultaneously dispatch multiple mobile charging piles to provide mobile charging for electric vehicles in the mobile charging vehicle list.

[0079] This invention employs a combination of fixed and mobile charging stations because the number of electric vehicles requiring charging fluctuates, and their parking locations are not fixed. This may lead to the following results:

[0080] After electric vehicle A is fully charged, the owner is still shopping or traveling and therefore still needs to park. In this case, electric vehicle A will remain parked on the suspended platform matched with the fixed charging station on the lower level. This may cause electric vehicle B, which arrives later and needs to be charged, to have to park on the suspended platform on the upper level that is not matched with a fixed charging station, and thus electric vehicle B will not be able to charge.

[0081] Deploying excessive fixed charging stations at this time can easily lead to additional costs due to the unpredictable number required. Therefore, this invention uses mobile charging stations to compensate for the fluctuating charging needs of electric vehicles.

[0082] This invention is implemented in a multi-level parking space, specifically employing a dual-movement method to reduce the number of charging stations. The first movement refers to the movement of electric vehicles: those requiring long-term charging are moved to lower levels to match fixed charging stations, while those not needing charging are moved to higher levels. The second movement refers to the movement of mobile charging stations, which are moved to charge the smaller number of electric vehicles that require charging. This dual-movement method is used because the number of electric vehicles needing charging fluctuates. A certain number of fixed charging stations can be set up (e.g., the number of electric vehicles corresponding to any point between peaks and troughs can be used as the number of fixed charging stations), and a certain number of mobile charging stations can be set up (e.g., the number of electric vehicles corresponding to the peaks minus the number of fixed charging stations can be used as the number of mobile charging stations). If the number of electric vehicles needing charging is at a trough, the fixed charging stations can meet the charging needs of all electric vehicles; if the number of electric vehicles needing charging is at a peak, the mobile charging stations can meet the charging needs of the remaining electric vehicles.

[0083] Therefore, in a preferred embodiment, parking requests sent by multiple electric vehicle terminals are acquired via the Internet of Things; wherein, before step S1, in which each parking request includes the expected driving trajectory, parking time, and current battery level of each electric vehicle terminal, the following steps are included:

[0084] Obtain the historical curve of the number of electric vehicles that need charging corresponding to the multi-level parking space;

[0085] Determine the highest and lowest points of the historical curve of the number of electric vehicles requiring charging.

[0086] The number of fixed charging piles can be calculated using the formula: Number of fixed charging piles = (Highest value - Lowest value / 2) + Lowest value.

[0087] The number of mobile charging stations can be calculated using the formula: Number of mobile charging stations = Maximum value point - Number of fixed charging stations.

[0088] The Internet of Things (IoT) connects at least the sensors installed on the implementing entity of this invention, the charging piles, the electric vehicle terminals, and each suspended platform. The implementing entity of this application is, for example, a server. Charging piles are divided into two categories: fixed charging piles and mobile charging piles. Fixed charging piles are located on the lower level of the multi-level parking space, and because the multi-level parking space is planar, fixed charging piles also have multiple layers to accommodate suspended platforms of different heights. Mobile charging piles are mainly located on the upper level of the multi-level parking space. Furthermore, the height of the highest fixed charging pile is less than that of the highest suspended platform, meaning that at least some suspended platforms are not equipped with fixed charging piles. These suspended platforms can either use mobile charging piles for mobile charging or be used to park electric vehicles that do not require charging.

[0089] Transportation equipment, such as elevator systems, can be used to move vehicles vertically and horizontally to different parking spaces. Users drive their electric vehicles into the elevator, which is located in the center of the multi-level parking space. A server, according to the present invention, determines the suspended platform where the electric vehicle should be parked and transports it to that platform.

[0090] Alternatively, mechanical platforms can be used as transport equipment. A mechanical platform is a specially designed device that can move vehicles up and down between different suspended platforms. They typically consist of one or more platforms that can rise and fall vertically to transport electric vehicles from the ground to the suspended platforms.

[0091] Mobile charging stations can be set up in the same way as transport equipment. However, since they do not need to transport much heavier electric vehicles, they are smaller and more flexible, making them easier to move in multi-level parking spaces. As they have the same features as transport equipment, they will not be described in detail here.

[0092] The sensors installed on each suspended platform can be any feasible sensors, such as pressure sensors or light signal sensors. In a preferred embodiment, the multi-level parking space is in a dark environment; the sensors are visible light sensors, and each suspended platform is equipped with a mark made of a light conversion material; the light conversion material can convert ultraviolet light into visible light; each suspended platform is equipped with an ultraviolet light generator; when an electric vehicle is parked on the suspended platform, the mark is blocked by the electric vehicle; when no electric vehicle is parked on the suspended platform, the mark is located within the sensing window of the visible light sensor; the step S4 of receiving the sensing signals sent by the sensors installed on each suspended platform through the Internet of Things and generating a list of vacant suspended platforms based on the sensing signals includes:

[0093] S401: The ultraviolet light generator emits ultraviolet light towards the corresponding mark;

[0094] S402: The visible light sensor performs sensing processing to obtain the sensing signal;

[0095] S403: The ultraviolet light generator stops emitting ultraviolet light, and the visible light sensor stops sensing and processing at the same time;

[0096] S404: Receives sensing signals from sensors installed on various suspended platforms via the Internet of Things and uses preset image recognition technology to determine whether the sensing signals contain markers.

[0097] S405: Store the suspended platform corresponding to the marked sensing signal into a pre-generated list of vacant suspended platforms.

[0098] This allows the three-dimensional parking space to operate in a dark environment. Furthermore, the invention employs non-real-time signal transmission, reducing network load and eliminating the need for continuous sensor operation, thus extending sensor lifespan. The light conversion material can be any feasible material, such as those based on semiconductor band structure theory. The principle is that the band structure of a semiconductor material can be divided into a valence band and a conduction band, where electrons in the valence band are bound and those in the conduction band are free. When ultraviolet light shines on these materials, electrons absorb the ultraviolet light, exciting their energy level from the ground level to a higher energy level. This higher energy level is unstable and will transition downwards. When the energy difference between these two levels matches the wavelength of visible light, macroscopically, this results in the absorption of ultraviolet light and the emission of visible light. To achieve the conversion of ultraviolet light to visible light, the band structure of the semiconductor material can generally be controlled, typically through appropriate material selection and doping.

[0099] As described in steps S1-S3 above, parking requests sent by multiple electric vehicle terminals are obtained through the Internet of Things. Each parking request includes the expected driving trajectory, parking time, and current battery level of each electric vehicle terminal. Based on a preset charging necessity judgment method, and using the expected driving trajectory, parking time, and current battery level as criteria, it is determined whether the electric vehicles corresponding to the multiple terminals require charging. Electric vehicles requiring charging are ranked last, and those not requiring charging are ranked first, thus generating an electric vehicle ranking table. This achieves intelligent charging, which is particularly suitable for large-scale applications in multi-level parking spaces. Users only need to plan their trips without worrying about the battery level of their electric vehicles, eliminating the hassle of charging – a significant advantage of this invention. Furthermore, users should grant charging permissions when parking to achieve intelligent charging.

[0100] As described in steps S4-S5 above, the system receives sensor signals from sensors installed on each suspended platform via the Internet of Things (IoT) and generates a list of vacant suspended platforms based on these signals. According to the electric vehicle ranking list and the list of vacant suspended platforms, a pre-set transport device is used to transport multiple electric vehicles to the suspended platforms of the multi-level parking space. Vehicles ranked lower in the electric vehicle ranking list are transported to lower vacant suspended platforms. The list of vacant suspended platforms records all available platforms. New electric vehicles should be parked on these platforms, but the placement is based on a rule: vehicles ranked lower in the electric vehicle ranking list are transported to lower vacant suspended platforms. This ensures that electric vehicles requiring charging are parked on lower platforms, facilitating charging with fixed charging stations, while electric vehicles not requiring charging are parked on higher platforms, where some have shorter parking times, allowing for quicker retrieval.

[0101] As described in step S6 above, the specified height value of the highest fixed charging pile is obtained, and a list of mobile charging vehicles is generated based on the specified height value. It is then determined whether the mobile charging vehicle list is empty. The electric vehicles in the mobile charging vehicle list share a common characteristic: the height of the suspended platform where they are parked is greater than the specified height value. The mobile charging vehicle list refers to the list of electric vehicles that require mobile charging. These electric vehicles should be parked at a height higher than the specified height value; otherwise, they can be charged using fixed charging piles.

[0102] As described in steps S7-S8 above, if the condition is empty, a fixed charging instruction is generated to instruct that electric vehicles requiring charging be charged only through fixed charging stations; if the condition is not empty, a comprehensive charging instruction is generated to instruct that electric vehicles requiring charging be charged through fixed charging stations, while simultaneously scheduling multiple mobile charging stations to charge electric vehicles in the mobile charging vehicle list. Charging can be divided into two types: basic fixed charging and mobile charging when the number of electric vehicles requiring charging exceeds the number of fixed charging stations.

[0103] In one embodiment, step S2, which determines whether the electric vehicles corresponding to multiple electric vehicle terminals have a charging necessity based on the expected driving trajectory, parking time, and current battery level according to a preset charging necessity determination method, includes:

[0104] S201: Extract the corresponding expected driving trajectory, parking time, and current battery level from the designated parking application corresponding to the designated electric vehicle terminal;

[0105] S202: Determine whether the parking time exceeds the preset duration and whether the current battery level exceeds the preset battery threshold;

[0106] S203: If the parking time is longer than the preset duration and the current battery level is not greater than the preset battery level threshold, the estimated driving mileage will be calculated based on the expected driving trajectory.

[0107] S204: Determine whether the current battery level is sufficient to support the estimated driving range;

[0108] S205: If the current battery level is insufficient to support the estimated driving range, the estimated parking location and parking time are extracted from the estimated driving trajectory, and the density of the first available charging piles corresponding to the estimated parking location is extracted from the preset electronic map; wherein, the location and status of the charging piles are marked on the electronic map.

[0109] S206: Obtain the density of the second available charging piles corresponding to the three-dimensional parking space, and determine whether the density of the first available charging piles is greater than the density of the second available charging piles;

[0110] S207: If it is not greater than, then it is determined that the electric vehicle corresponding to the specified electric vehicle terminal needs to be charged.

[0111] The predicted driving trajectory and parking time are set by the vehicle owner. Therefore, this invention can also be applied to electric vehicles using autonomous driving technology. The owner does not need to worry about the current battery level. This invention can intelligently identify whether the electric vehicle should be charged based on the predicted driving trajectory, parking time, and current battery level. Specifically, the density of available charging stations corresponding to the predicted parking location is used. If the density of available charging stations at that parking location remains relatively constant, the density at the current time is used; if the density fluctuates, the density at the time the electric vehicle arrives at that parking location is used. By comparing densities, macroscopic-level charging optimization can be achieved.

[0112] In one embodiment, the plurality of fixed charging piles includes at least a portion of wireless charging piles, and one wireless charging pile is capable of charging at least two electric vehicles located on adjacent suspended platforms; step S5, which involves transporting the plurality of electric vehicles to the suspended platforms of the multi-level parking space using a preset transport device based on an electric vehicle sorting table and a list of vacant suspended platforms, includes:

[0113] S501: Based on the standard of whether wireless charging is possible, electric vehicles that need to be charged in the electric vehicle ranking list are clustered to generate a first cluster and a second cluster; wherein, the first cluster includes electric vehicles that can be wirelessly charged, and the second cluster includes electric vehicles that cannot be wirelessly charged.

[0114] S502: Based on the electric vehicle sorting list and the list of vacant suspended platforms, using a preset transport device, the electric vehicle ranked first in the electric vehicle sorting list is transported to the highest vacant suspended platform, then the electric vehicle ranked second first in the electric vehicle sorting list is transported to the second highest vacant suspended platform, and so on, until all electric vehicles in the electric vehicle sorting list that do not require charging are transported to the vacant suspended platforms.

[0115] S503: Based on the electric vehicle sorting table and the list of vacant suspended platforms, use the preset transport equipment to transport electric vehicles belonging to the first cluster to the suspended platform equipped with wireless charging piles; transport electric vehicles belonging to the second cluster to the suspended platform equipped with other fixed charging piles.

[0116] This, combined with wireless charging technology, further optimizes the number of charging stations and reduces costs. This is possible because it's implemented in a multi-level parking space; one wireless charging station can charge multiple adjacent suspended platforms, resulting in more charging stations compared to a surface parking lot, thus requiring fewer fixed charging stations. Furthermore, transporting multiple electric vehicles to the suspended platforms of the multi-level parking space can be done by parking vehicles needing charging sequentially from lower to higher levels, and vehicles not needing charging sequentially from higher to lower levels.

[0117] In one embodiment, the minimum movable height of the multiple mobile charging piles is greater than the height of the highest fixed charging pile. Therefore, the movement of the multiple mobile charging piles only occurs in the upper space, which is beneficial for rapid deployment and fast charging. Of course, the fact that the minimum movable height of the multiple mobile charging piles is greater than the height of the highest fixed charging pile is only a preferred embodiment of the present invention. In some special scenarios, the multiple mobile charging piles can also be moved to the lower space.

[0118] In one embodiment, multiple mobile charging stations are configured to be dispatchable throughout the entire multi-level parking space; after step S7, which generates a fixed charging instruction to instruct electric vehicles requiring charging to be fixedly charged only through fixed charging stations, the following steps are included:

[0119] S71: Receives fault signals sent by designated fixed charging piles via the Internet of Things;

[0120] S72: Dispatch an idle mobile charging station to descend to the designated fixed charging station and replace the designated fixed charging station to charge the corresponding electric vehicle.

[0121] In this embodiment, mobile charging stations can also be used for supplementary charging. Fixed charging stations may malfunction. When a fixed charging station malfunctions, an idle mobile charging station can be dispatched to lower itself to a designated fixed charging station and replace the designated fixed charging station to charge the corresponding electric vehicle. This method achieves supplementary charging without changing the overall parking standards and layout of electric vehicles.

[0122] This application presents an IoT-based intelligent scheduling method for charging piles. The method acquires parking requests from multiple electric vehicle terminals; determines whether the electric vehicles corresponding to these terminals require charging; generates an electric vehicle sorting table; generates a list of vacant suspended platforms; transports the multiple electric vehicles to the suspended platforms of a multi-level parking space; generates a list of mobile charging vehicles; and generates fixed charging instructions or comprehensive charging instructions. Thus, in a multi-level parking space, and with the assistance of multiple fixed charging piles of varying heights and multiple mobile charging piles, the method can meet the charging needs of electric vehicles with a relatively small number of charging piles deployed.

[0123] Reference Figure 2This application provides an IoT-based intelligent scheduling device for charging piles. The charging piles are located within a multi-level parking space, and include multiple fixed charging piles and multiple mobile charging piles of varying heights. The multi-level parking space includes multiple suspended platforms for parking electric vehicles and transport equipment for transporting electric vehicles. Multiple fixed charging piles are located in the center of the multi-level parking space, and each fixed charging pile corresponds to a suspended platform. The height of the highest fixed charging pile is less than that of the highest suspended platform.

[0129] The transport module 50 is used to transport multiple electric vehicles to the suspended platforms of the multi-level parking space using preset transport equipment, based on the electric vehicle sorting list and the list of vacant suspended platforms; among them, vehicles that are ranked later in the electric vehicle sorting list are transported to vacant suspended platforms with a lower height.

[0130] The second judgment module 60 is used to obtain the specified height value of the highest fixed charging pile, generate a list of mobile charging vehicles based on the specified height value, and determine whether the list of mobile charging vehicles is empty; wherein, the electric vehicles in the list of mobile charging vehicles have a common feature: the height value of the suspended platform on which they are parked is greater than the specified height value.

[0131] The fixed charging module 70 is used to generate a fixed charging instruction if it is empty, to instruct that electric vehicles that need charging should only be charged via fixed charging piles.

[0132] The integrated charging module 80 is used to generate an integrated charging instruction if it is not empty, to instruct the electric vehicles that need charging to be charged through fixed charging piles, and at the same time to dispatch multiple mobile charging piles to charge the electric vehicles in the mobile charging vehicle list.

[0133] In one embodiment, the step of determining whether electric vehicles corresponding to multiple electric vehicle terminals need charging based on a preset charging necessity judgment method, using the expected driving trajectory, parking time, and current battery level as criteria, includes:

[0134] Extract the corresponding estimated driving trajectory, parking time, and current battery level from the designated parking application corresponding to the designated electric vehicle terminal;

[0135] Determine whether the parking time exceeds the preset duration and whether the current battery level exceeds the preset battery threshold;

[0136] If the parking time exceeds the preset duration and the current battery level is not greater than the preset battery level threshold, the estimated driving mileage will be calculated based on the expected driving trajectory.

[0137] Determine if the current battery level is sufficient to support the estimated driving range;

[0138] If the current battery level is insufficient to support the estimated driving range, the estimated parking location and parking time are extracted from the estimated driving trajectory, and the density of the first available charging piles corresponding to the estimated parking location is extracted from the preset electronic map; the location and status of the charging piles are marked on the electronic map.

[0139] Obtain the density of the second available charging piles corresponding to the three-dimensional parking space, and determine whether the density of the first available charging piles is greater than the density of the second available charging piles;

[0140] If the value is not greater than the specified value, then the electric vehicle corresponding to the specified electric vehicle terminal is determined to have a need for charging.

[0143] Based on the electric vehicle ranking list and the list of vacant suspended platforms, a pre-set transport device is used to transport the electric vehicle ranked first in the electric vehicle ranking list to the highest vacant suspended platform, then the electric vehicle ranked second first in the electric vehicle ranking list to the second highest vacant suspended platform, and so on, until all electric vehicles in the electric vehicle ranking list that do not require charging are transported to the vacant suspended platforms.

[0144] Based on the electric vehicle sorting table and the list of vacant suspended platforms, electric vehicles belonging to the first cluster are transported to suspended platforms equipped with wireless charging piles using pre-set transport equipment; electric vehicles belonging to the second cluster are transported to suspended platforms equipped with other fixed charging piles.

[0145] In one implementation, the minimum movable height of the plurality of mobile charging piles is greater than the height of the highest fixed charging pile.
