Description

Technical Field

[0001] This invention relates to the fields of new energy vehicle charging and advertising, specifically to an advertising display method based on an aerial mobile charging robot. Background Technology

[0002] With the fierce competition in the charging pile market, the current problems facing the new energy electric vehicle charging industry mainly include: (1) The payback period for charging operators is long, especially when the industry is in a state of infighting and price wars, the charging profit is even thinner, and there is no other way to make a profit except for the difference in charging service fees. Therefore, the payback period for charging operators is significantly extended, which damages the sustainable development of the industry. (2) Parking spaces suitable for building commercial charging piles are generally located in good locations, and the site costs are high, resulting in high overall costs for station-type commercial charging piles. (3) The construction of a large number of charging piles will result in high construction costs and low utilization rates, which wastes resources and increases the distribution pressure on the power grid. (4) The problem of charging pile parking spaces being occupied by fuel vehicles cannot be solved, resulting in either wasting parking space resources or wasting charging pile resources. Therefore, it is necessary to develop an intensive electric vehicle charging solution. This charging solution does not require the construction of charging piles for each parking space, and car owners do not need to specifically look for charging points. As long as the car is parked in the service coverage area where this intensive electric vehicle charging solution is deployed, convenient and fast charging can be achieved. In addition, if charging facilities can create new revenue streams for charging operators, it can enhance their profitability and promote the sustainable development of the industry.

[0003] In their previously filed Chinese patent applications, "A Suspended Mobile Charging Pile System with Four-Wheel Independent Drive and Steering" (application number: 2023201748902) and "A Suspended Track Four-Wheel Independent Steering and Traveling System" (application number: 2023214703187), the inventors proposed a variable-track aerial track-based mobile charging solution. This solution provides on-demand charging services for electric vehicles in any parking space below intersecting tracks, decoupling the relationship between parking spaces and charging piles, transforming the process from "cars looking for piles" to "pile looking for cars," completely solving the problem of gasoline vehicles occupying charging spaces, and improving the efficiency of charging resource utilization and the user charging experience. Based on track-based mobile charging technology, this invention proposes an advertising display method based on an aerial mobile charging robot. A large screen is installed on the charging robot, which can display advertisements both when stationary and while moving. This allows charging operators to obtain considerable advertising revenue in addition to charging revenue, thus greatly improving the profitability of charging operators, accelerating their return on investment, and promoting the rapid and healthy development of the entire charging industry. Summary of the Invention

[0004] The purpose of this invention is to provide an advertising display method based on an aerial mobile charging robot. The charging robot can move along an aerial track and provide mobile charging services to electric vehicles parked in parking spaces below the track. In addition, a screen for displaying advertisements is provided on the surface of the charging robot. The charging robot can display advertisements both when stationary and while moving. The advertising screen while moving is more attractive to people, and therefore has a higher advertising value. This allows charging operators to obtain considerable advertising revenue in addition to charging revenue, thus greatly improving the profitability of charging operators and accelerating their return on investment.

[0005] To achieve the above-mentioned objectives, the corresponding technical solution is as follows: An advertising display method based on an aerial mobile charging robot, wherein the aerial mobile charging robot can move along an aerial track, and the power for its movement along the aerial track is provided by a walking module installed on the charging robot. The aerial mobile charging robot is equipped with a screen for displaying advertisements, the advertisements to be displayed being referred to as candidate advertisements. The advertising display method includes: Set up an advertising display program that includes playback logic, wherein the playback logic includes which candidate advertisement or which group of candidate advertisements to play when the air-mobile charging robot is in which state; Get the current status of the aerial mobile charging robot; The advertising display program displays candidate advertisements on the screen based on the current state of the aerial mobile charging robot and the playback logic.

[0006] Preferably, the aerial mobile charging robot's state includes an idle state with no charging task, and the candidate advertisements include an idle advertisement group containing multiple advertisements to be displayed when the aerial mobile charging robot is in an idle state. The advertisement display method includes: setting an automatic movement program; when the current state of the aerial mobile charging robot is idle with no charging task, the automatic movement program causes the aerial mobile charging robot to move along the aerial track according to the movement mode set by the automatic movement program; and the advertisement display program displays the advertisements in the idle advertisement group through the screen during the movement. The charging robot moves autonomously and displays advertisements when it is idle with no charging task, which can fully utilize the robot's movement to attract attention, thereby achieving higher advertising value and effectiveness.

[0007] Preferably, the aerial track is a one-way track, and the automatic movement program is set to move back and forth along the one-way track. During the back and forth movement, the advertising display program displays advertisements from the idle advertising group on the screen.

[0008] Preferably, the aerial track is an intersecting track, and the aerial mobile charging robot includes a traveling and turning unit, which is the walking module mentioned above. The traveling and turning unit enables the aerial mobile charging robot to travel along the intersecting track and turn at the intersection of the intersecting track. The automatic movement program is set to move cyclically along the intersecting track according to a set path. During the cyclic movement, the advertising display program displays advertisements from the idle advertising group through the screen.

[0009] Preferably, the state of the aerial mobile charging robot includes a state of responding to a charging call. The candidate advertisements include charging guidance advertisements and a group of advertisements in response. The charging guidance advertisements contain tutorials guiding users on how to correctly use the aerial mobile charging robot. The group of advertisements in response contains multiple advertisements that need to be displayed while the charging robot is responding to a charging call request. The advertisement display method includes: when the current state of the aerial mobile charging robot is responding to a charging call, the advertisement display program first displays the charging guidance advertisement on the screen, and then displays the advertisements in the group of advertisements in response. Displaying the charging guidance advertisement can better guide users on how to correctly use the charging robot to charge their cars. While providing convenience to users, it can also reduce maintenance problems caused by improper use and lower the equipment failure rate. Displaying the charging guidance advertisement first, followed by the commercial advertisement, results in a higher value for the commercial advertisement displayed. This is because while users are waiting for the charging robot to move after scanning the code, their attention will be focused on the charging robot. Therefore, the advertisement displayed at this time will leave a deeper impression on the user. Thus, the commercial advertisement displayed at this time can be set as a VIP priority advertisement.

[0010] Preferably, the state of the aerial mobile charging robot includes a charging state, the candidate advertisements include a charging advertisement group, the charging advertisement group contains multiple advertisements that need to be displayed when the aerial mobile charging robot is in a charging state, and the advertisement display method includes: when the current state of the aerial mobile charging robot is a charging state, the advertisement display program displays the advertisements in the charging advertisement group through the screen.

[0011] Preferably, the states of the aerial mobile charging robot include a "charging complete, charging gun not unplugged" state, and the candidate advertisements include a "unplug prompt" advertisement containing a prompt message that charging is complete and the charging gun should be unplugged. The advertisement display method includes: when the current state of the aerial mobile charging robot is "charging complete, charging gun not unplugged," the advertisement display program displays the "unplug prompt" advertisement on the screen. Displaying the "unplug prompt" advertisement helps solve the problem of users not being able to unplug the charging gun in time after it is fully charged, which can greatly improve the utilization rate of the charging robot and the utilization rate of charging resources.

[0012] Preferably, the aerial mobile charging robot is also equipped with a voice playback module, which is used to play the audio corresponding to the advertisement displayed on the screen.

[0014] Preferably, the advertising file for display is pushed to the aerial mobile charging robot via remote network push, and the advertising display program can read the advertising file and display it on the screen.

[0015] The beneficial effects of this invention are: (1) In addition to realizing mobile charging in the air, the present invention also has good advertising display capabilities. The charging robot can display advertisements when stationary or when moving. This allows charging operators to obtain considerable advertising revenue in addition to charging revenue, thus greatly improving the profitability of charging operators and accelerating the return on investment for charging operators. (2) Mobile advertising screens are more likely to attract people's attention, and therefore have a higher advertising value; (3) When the charging robot is in different states, different advertisements can be displayed in a customized manner, which enriches the function and practicality of the screen and also improves the value of the advertisement display. (4) Displaying charging guidance advertisements can better guide users on how to properly use the charging robot to charge their cars. While providing convenience to users, it can also reduce maintenance problems caused by improper use and lower the failure rate of the equipment. (5) During the process of the charging robot responding to the charging call request, the charging guidance advertisement is displayed first, and then the commercial advertisement is displayed. The commercial advertisement displayed at this time has a higher value because the user's attention will be focused on the charging robot while waiting for the charging robot to move over after scanning the code. Therefore, the advertisement displayed at this time will leave a deeper impression on the user. So the commercial advertisement displayed at this time can be set as a VIP key advertisement. (6) The charging robot can move and display advertisements on its own when it is idle and has no charging task. It can make full use of the movement of the charging robot to attract people's attention, thereby achieving higher advertising value and advertising effect. (7) The charging robot plays a gun-unplugging prompt advertisement on the screen after charging is completed, which helps to solve the problem of users not being able to unplug the gun in time after the battery is fully charged. This can greatly improve the utilization rate of the charging robot and the utilization rate of charging resources.

[0035] Preferably, the advertising file for display is pushed to the aerial mobile charging robot via remote network push, and the advertising display program can read the advertising file and display it on the screen.

[0036] The implementation of this invention is based on an aerial mobile charging robot. The following description and explanation of the aerial mobile charging robot and its related system implementation scheme are presented in conjunction with the accompanying drawings.

[0037] Figure 1-6 The diagram illustrates the operation of the aerial mobile charging robot. Preferably, in addition to the charging robot itself, the operation of the aerial mobile charging robot also requires an aerial track, a communication unit, a robot positioning system, a call response system, and a power supply unit. The charging robot includes a control unit, a charging function module, a walking module, and a screen. Several charging robots are deployed suspended on the aerial track. Their actions and functional logic are controlled by the control unit. The charging function module enables the charging robot to charge electric vehicles. The walking module drives the charging robot to move along the aerial track. The screen displays advertising content. The control unit also includes an advertising display control module, which controls the advertising content and display logic on the screen. The communication unit provides communication capabilities to the system. The robot positioning system determines the position of the charging robot on the aerial track. The call response system responds to users' charging requests. The power supply unit supplies power to the system.

[0038] Preferred, such as Figure 1-4As shown, this is a first preferred embodiment of the operation of the charging robot. In this embodiment, the aerial track is a single-track track 4, the charging robot is a single-track charging robot 2, and the walking module is a forward and reverse walking module. The forward and reverse walking module can walk forward or backward along the single-track track 4. Preferably, the forward and reverse walking module includes a walking support frame 203, a walking wheel set 204, and a single-track walking motor. The walking wheel set 204 is driven to rotate by the single-track walking motor. Preferably, the monorail charging robot 2 further includes an RFID positioning module. The RFID positioning module is a component of the robot positioning system described above. The RFID positioning module is installed on the upper surface of the monorail charging robot 2, with its reading direction vertically upward. Positioning RFID electronic tags are set at important positioning points, such as stopping points, on the lower surface of the single-track track 4. Each stopping point is bound to the positioning RFID electronic tag set there. When the monorail charging robot 2 moves to the corresponding position, the RFID positioning module can read the position information through the positioning RFID electronic tag, thereby performing corresponding actions, such as stopping at a certain stopping point and putting down the charging gun cable.

[0039] Preferably, the first preferred power supply method for the monorail charging robot 2 is sliding contact line power supply. A sliding contact power-taking device is provided on the monorail charging robot 2, and a sliding contact line is provided in the single-track 4. When the monorail charging robot 2 moves along the single-track 4, the sliding contact power-taking device maintains power-taking contact with the sliding contact line, thereby supplying power to the monorail charging robot 2.

[0040] Preferably, the second preferred power supply method for the monorail charging robot 2 is cable chain power supply. The internal space of the single-track 4 is divided into two parts, including a walking groove 401 and a cable chain groove 402. The monorail charging robot 2 is connected to an external input power source through a cable chain 5. The moving space of the cable chain 5 is the cable chain groove 402, and the moving space of the forward and reverse moving module is the walking groove 401.

[0041] Preferably, the monorail charging robot 2 further includes a monorail screen 201, and the charging cable includes a monorail charging gun 202 and a monorail charging cable 205. The monorail charging cable 205 is wound and unwound by the cable winding module. Preferably, the cable winding module includes a monorail winding motor and a monorail winding reel. The monorail charging cable 205 is wound on the monorail winding reel, and the cable winding module winds and unwounds the monorail charging cable 205 by a winding method, the power for which comes from the monorail winding motor.

[0042] Preferred, such as Figure 5-6The diagram shows a second preferred embodiment of the charging robot's operation. In this embodiment, the aerial track is a cross track, its path including several straight sections, several intersections, and at least zero turning sections. The charging robot is a track-changing version of the charging robot 1, and the walking module is a four-wheel independent steering drive unit, i.e., the aforementioned travel and steering unit. The four-wheel independent steering drive unit can drive the track-changing charging robot 1 to move along the track path of the cross track, and to turn at the intersections of the cross track according to the needs of the travel route. Preferably, the cross track adopts a combination of main roads and branch roads, such as... Figure 5 As shown, the cross track includes a main road 8, a branch road 6, and a cross passage 7. The track-changing charging robot 1 is located in the branch road when idle and when charging electric vehicles. It will only temporarily enter the main road when moving from one branch road to another, thus ensuring the smooth flow of the main road.

[0043] Preferably, the track-changing charging robot 1 further includes a power-collecting module and a battery, and a power-collecting circuit is arranged along the intersecting tracks. The power-collecting module, battery, and power-collecting circuit are components of the power supply unit described above. When the track-changing charging robot 1 moves to a location requiring power, the power-collecting module draws power from the power-collecting circuit, thereby connecting to an external power source. During the movement of the track-changing charging robot 1, the electrical energy required for its movement is provided by the battery. Specific implementations of the power-collecting device and power-collecting circuit have been disclosed in the patent documents mentioned in the background section of this invention, and will not be repeated here.

[0044] Preferably, the track-changing charging robot 1 includes a track-changing screen 101, a track-changing shell 102, a four-wheel independent steering drive unit, a power supply module, a positioning module, a track-changing charging gun 103, and a track-changing charging cable. Preferably, the four-wheel independent steering drive unit includes a track-changing support plate 105, a steering power motor set 106, and a walking power wheel set 107. Specific implementations of the four-wheel independent steering drive unit have been disclosed in the patent documents mentioned in the background section of this invention, and will not be repeated here. Preferably, the positioning module is a QR code reading positioning module 104. Preferably, the QR code reading positioning module 104 is installed on the upper surface of the track-changing charging robot 1, with its reading direction vertically upward. Positioning QR codes are affixed to important positioning points on the lower surface of the intersecting tracks, such as intersections and power-taking points. Each positioning point is bound to its corresponding positioning QR code. When the track-changing charging robot 1 moves to the corresponding position, the QR code reading positioning module 104 can read the accurate position information through the positioning QR code, thereby performing the corresponding action. For example, at the intersection of the intersecting tracks, it needs to stop and perform a track-changing turning action; at the power-taking point of the branch road, it needs to stop and perform a power-taking action. Preferably, the QR code reading positioning module 104 can be a commonly used QR code positioning reader in the AGV industry. Since this type of reader, which requires high-speed reading and positioning, differs from ordinary QR code readers, an optional model is provided here for ease of implementation of the technical solution of this patent, such as the Dahua R3138MG010 reader.

[0045] The call response system is used to respond to users' charging needs. Preferably, the call response system also includes a charging QR code system and a scheduling system. Preferably, the scheduling system is deployed in the cloud. The charging QR code system contains several charging QR codes, each bound to a specific parking space location. When a user scans a charging QR code using a mobile terminal, such as a mobile phone, a charging call request is initiated. This charging call request is sent to the scheduling system via the mobile communication network. The scheduling system then dispatches a nearby available charging robot to the parking space bound to the charging QR code and lowers the charging cable, thus realizing the charging robot's call response. Preferably, the scheduling system also includes a path map. The path map records the binding relationship between the charging QR code and the parking space, the binding relationship between the location point and the track path of the aerial rail, and the relative positional relationship between the parking space and the track path of the aerial rail. When scheduling the charging robot, the scheduling system performs path planning and scheduling based on the path map.

[0046] Preferably, the control unit should have at least the capability of data analysis, processing, and control. It can be a general-purpose chip, such as a central processing unit (CPU) or a microprocessor (MCU), or a dedicated processing and control chip, or a circuit board module with the aforementioned chips as the main control chip. The control unit typically carries programs or software that implement the corresponding functions. The control unit can be a single integrated control processor or it can be composed of multiple control processors.

[0047] The communication unit provides the system with the ability for communication between devices. This communication can include communication between the charging robot and the call response system, communication between the user terminal device and the call response system, and communication between different charging robots. Each of these communication objects typically requires corresponding communication hardware and software modules. Preferably, the communication unit uses common wireless communication methods, such as Wi-Fi or mobile communication networks. Preferably, the communication unit also includes a robot-side communication module, which is deployed on the charging robot and connected to the control unit.

[0048] Preferably, the control unit further includes a charging robot status monitoring unit, and the advertising display control module includes an advertising display program with set advertising display content and display logic. The charging robot's status includes an idle state with no charging task, a state responding to a charging call, a state in progress, and a state where charging is complete but the charging gun is not disconnected. Specifically, the idle state with no charging task refers to a state where the charging robot is neither charging an electric vehicle nor responding to a charging call, and the charging gun is fully retracted; the responding state refers to a state where the charging robot has received a charging task but has not yet fully moved into position and disconnected the charging gun; the charging state refers to a state where the charging robot is charging an electric vehicle; and the state where charging is complete but the charging gun is not disconnected refers to a state where the charging process of the electric vehicle has ended, but the charging robot's charging gun is still plugged into the electric vehicle's charging port. The charging robot status monitoring unit can monitor which of the above states the charging robot is in. The advertising display control module can obtain the charging robot's status through the control unit and thus display corresponding advertisements according to the advertising display content and display logic set in the advertising display program when the charging robot is in different states. The advantage of this setup is that different advertisements can be customized to be displayed depending on the charging robot's state. For example, when a user scans a code, the charging robot is responding to a charging call. It can first display a tutorial advertisement guiding the user on how to correctly use the system, followed by a commercial advertisement. Moreover, the commercial advertisement displayed at this time has higher value because the user's attention will be focused on the charging robot while waiting for it to move. Therefore, the advertisement displayed at this time will leave a more lasting impression. Thus, the commercial advertisement displayed at this time can be set as a VIP priority advertisement. As another example, when the charging robot is idle and not performing a charging task, it can continuously display commercial advertisements or introductory advertisements about the system. Furthermore, the charging robot can move back and forth along the aerial track during the advertisement display process. This back-and-forth movement also aims to make the displayed advertisement content more attention-grabbing, increasing the advertising value.

[0049] Preferably, the charging robot further includes an audio module for playing audio corresponding to the advertising content displayed on the screen. With the addition of the audio module, the screen can play video advertisements with sound in addition to image advertisements.

[0050] Preferably, the charging function module includes a charging controller, a charging gun cable, and a cable retraction module. The charging controller controls the charging process when the charging robot charges the electric vehicle, and the cable retraction module is used to retract and extend the charging gun cable. In specific implementations, except for the cable retraction module, the system architecture, component composition, and related functions of the charging function module are basically the same as those of traditional fixed charging piles. Therefore, the relevant technical solutions and modules of fixed charging piles can be directly adopted. These technical solutions are already very mature and will not be elaborated here. Preferably, when the charging function module is a DC fast charging module, it usually also includes a power module. The power module is used to convert the input voltage of the external input terminal into an output voltage that can directly charge the car battery. The power module is a mature technology in the charging pile industry, and its technical details will not be elaborated here. Preferably, the charging controller can be a charging control board commonly used in the charging pile industry, such as a common AC charging control board or DC charging control board. Since the application of related technologies is already very widespread, their technical details will not be elaborated here. The take-up and unwinding module can be a commonly used winding take-up and unwinding module. The winding take-up and unwinding module usually uses a winding reel or winding roller to achieve the winding and unwinding of the charging gun cable. The rotation power of the winding reel or winding roller can be provided by a motor. The related technology of winding take-up and unwinding is also a very mature technology in the industry, and its technical details will not be elaborated here.

[0051] Preferred, such as Figure 1 , Figure 5As shown, the aerial track is deployed above the parking spaces in the parking lot. The screen is oriented such that the normal of the plane containing the screen is parallel to the long side 1201 of the parking space frame 12 below the charging robot. It should be noted that this parallelism does not require strict alignment; approximate parallelism is sufficient. The advantage of this arrangement is that, typically when parking spaces are arranged in rows, the aisle direction is parallel to the short side 1202 of the parking space frame 12. In this case, the screen orientation is perpendicular to the aisle direction, allowing pedestrians in the aisle to see the screen from a better angle, thus achieving optimal display effects. Preferably, when the parking spaces below the area where the aerial track is located are back-to-back, the number of screens on the charging robot is set to two, with the normals of the two screens parallel to each other but facing opposite directions. In a back-to-back parking space layout, pedestrians in both aisles can see the advertisements displayed on the screens, achieving a very good advertising display effect. Furthermore, in the screen industry, a screen with a high percentage of its surface area relative to the total area of ​​its plane is typically referred to as a full-screen display. Preferably, on the side of the charging robot where the screen is located, the ratio of the screen's surface area to the total area of ​​that side is greater than or equal to 80%, indicating a full-screen design. The advantage of a full-screen design is that, given the limited size of the charging robot's casing, and the fact that it is suspended on an overhead track with a distance typically greater than 3 meters from pedestrians, a screen as large as possible needs to be placed within the limited casing space. Otherwise, the advertising display effect will be very limited. Therefore, the screen on the charging robot should adopt a narrow-bezel full-screen design, thus achieving a larger screen display area within the limited casing space. Additionally, the full-screen design is more stylish and aesthetically pleasing.
