[0021] The present invention is described below based on embodiments, but the invention is not limited to these embodiments. In the detailed description of the invention below, certain specific details are described in detail. Those skilled in the art will fully understand the invention even without these details. To avoid obscuring the essence of the invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0022] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0023] Furthermore, it should be understood that in the following description, "circuit" refers to a conductive loop consisting of at least one element or sub-circuit connected by electrical or electromagnetic connections. When an element or circuit is said to be "connected" to another element or "connected" between two nodes, it can be directly coupled or connected to another element, or there may be intermediate elements. The connection between elements can be physical, logical, or a combination thereof. Conversely, when an element is said to be "directly coupled to" or "directly connected" to another element, it means that there are no intermediate elements between them.

[0024] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application documents should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0025] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0026] Figure 1 This is a schematic diagram of the structure of the charging pile provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the charging pile includes a base 11 and a charging pile body 12. In one embodiment, the base 11 is embedded in the ground, and the charging pile body 12 is mounted on the base 11. Figure 2 This is a schematic diagram of a charging pile module provided in an embodiment of the present invention, combined with... Figure 1-2As shown, the charging pile also includes a central control module 1, a 5G communication module 2, a wireless local area network module 3, and a memory 4 integrated on the charging pile body 12. It is easy to understand that the 5G communication module 2, the wireless local area network module 3, and the memory 4 are respectively connected to the central control module 1.

[0027] Furthermore, Figure 3 This is a schematic diagram of the workflow of a central control module provided in an embodiment of the present invention, such as... Figure 3 As shown, the central control module 1 first receives the unicast request signal sent by the source base station through the 5G communication module 2 (i.e., step S1), then reserves storage space in the memory 4 according to the unicast request signal and sends a ready-to-receive signal to the source base station through the 5G communication module 2 (i.e., step S2). Afterwards, it receives the user's pending information sent by the source base station through the 5G communication module 2 and stores it in the storage space of the memory 4 (i.e., step S3). Finally, it forwards the user's pending information through the 5G communication module 2 or the wireless local area network module 3 (i.e., step S4). Specifically, the user's pending information can be forwarded to other charging piles near the current charging pile or directly to the user terminal through the 5G communication module 2, or it can be forwarded to other charging piles through the wireless local area network module 3. It should be noted that the user's pending information includes information that the source user needs to send to the terminal user. Therefore, the 5G communication module 2 can act as the WAN end of the charging pile to realize the function of a 5G micro base station, and the wireless local area network module 3 can also act as the LAN end of the charging pile to provide high-quality wireless network services to charging pile users or 5G network users. In one implementation, when the network quality of the wireless local area network module 3 is too poor or it is interrupted by interference, the 5G communication module 2 can temporarily take over the wireless network service from the wireless local area network module 3. Thus, the charging station can both provide charging services to users and function as a 5G NR multi-hop relay base station.

[0028] It should be noted that, in one implementation, the 5G communication module 2 is implemented using the 5G NR technology standard. The operating frequency band can be based on the 3.5GHz bands of n77 and n78, supplemented by service frequency bands provided by regional providers, such as n1 (2100MHz), n3 (1800MHz), n28 (700MHz), and n41 (2500MHz). On the other hand, the 5G NR Radio Access Network (RAN) is primarily composed of macrocells, with additional small cells deployed within to form a heterogeneous network. Full frequency reuse is used between small cells, and all base stations have backhaul (BH) capacity. The use of multi-hop relay technology can improve mobile broadband service and save network bandwidth consumption and power consumption of the transmitting base station. Therefore, the central control module 1 can achieve communication connection with the source base station through the 5G communication module 2. In this embodiment, the 5G communication module 2 and the wireless local area network module 3 are independent of each other. When the wireless local area network module 3 fails, the 5G communication module 2 can be used for emergency communication and information transmission. Alternatively, when the 5G communication module 2 is disconnected, the wireless local area network module 3 can connect to other charging piles via wireless local area network to forward the information of the source user to other charging piles.

[0029] It should be further explained that, in one embodiment, the wireless local area network module 3 is a dual-band wireless local area network module (including ISM 2.4GHz and ISM 5GHz), which acts as a wireless access point in the charging pile. In this embodiment, the central control module 1 continuously broadcasts the service set identifier (SSID) through the wireless local area network module 3 at fixed intervals, enabling users to use mobile phones, tablets, and other electronic devices to search for and connect to the wireless local area network service set identifier designated by the charging pile, thereby enjoying the network services provided by the charging pile. As an optional implementation, the wireless local area network module 3 uses three encryption methods—WEP, WPA3, and WPA-PSK / WPA2-PSK—to ensure the confidentiality of the network service for users.

[0030] Figure 4 This is another schematic diagram of the workflow of the central control module provided in this embodiment of the invention, such as... Figure 4As shown, in one embodiment, the central control module 1 is further configured to send an acknowledgment signal to the source base station via the 5G communication module 2 (i.e., step S5) to confirm whether the source base station has finished transmitting the user's pending information. It is readily understood that when the central control module 1 confirms that the user's pending information has been received, it will pause receiving and forward the user's pending information stored in the memory 4 (i.e., step S61), thus ceasing the communication connection with the source base station. Specifically, the user's pending information can be forwarded to other charging piles or directly to the user terminal via the 5G communication module 2, or it can be forwarded to other charging piles via the wireless local area network module 3. Correspondingly, when the central control module 1 confirms that the user's pending information has not been received, it will continue receiving the user's pending information (i.e., step S62), thus maintaining the communication connection with the source base station.

[0031] Figure 5 This is another schematic diagram of the workflow of the central control module provided in this embodiment of the invention, such as... Figure 5 As shown, in one embodiment, the central control module 1 is further configured to determine the connection status of the 5G communication module 2 (i.e., step S7). Specifically, when the connection between the 5G communication module 2 and the source base station, user terminal, or other charging piles near the current charging pile is uninterrupted, the central control module 1 can continue to wirelessly communicate with the source base station, user terminal, or other charging piles through the 5G communication module 2 (i.e., step S81). On the other hand, when the connection between the 5G communication module 2 and other nearby charging piles is interrupted, the central control module 1 can switch to wirelessly communicating with other charging piles through the wireless local area network module 3 (i.e., step S82) to ensure the function of the charging pile as a multi-hop relay base station.

[0032] Combination Figure 1-2 As shown, in one embodiment, the charging pile further includes an environmental parameter sensing module 5, which is connected to the central control module 1. It should be noted that the environmental parameter sensing module 5 in this embodiment includes various sensors capable of sensing environmental parameters, such as temperature sensors, humidity sensors, or air quality sensors, thereby enabling the sensing of temperature, humidity, and air quality (e.g., PM2.5, PM10, CO, ozone, etc.). Furthermore, the central control module 1 can transmit the relevant environmental parameters to a meteorological bureau or an operator's cloud server via a 5G communication module 2. Thus, multiple charging piles facilitate the application of the Internet of Things (IoT) or Artificial Intelligence of Things (AIoT), such as enabling real-time weather forecasting, smart homes, industrial automation, and autonomous driving.

[0033] Combination Figure 1-2As shown, in one embodiment, the charging pile further includes a display module 6, which is connected to the central control module 1. It should be noted that the display module 6 in this embodiment includes an electronic information display board 61, a meter 62, and a touch screen 63. The electronic information display board 61 can be used to display advertisements, news, or information received via the 5G communication module 2, such as the charging pile user's membership information and payment status. Alternatively, it can display real-time collected information such as the license plate information of the user's electric vehicle and other information. The meter 62 can be used to display the user's electric vehicle's charging amount information to provide charging billing reference. The touch screen 63 can be used to display service options for user touch selection, or it can be used to display detailed metering and billing information, membership information and payment status, wireless area network service information, environmental sensing parameter information, 5G micro base station service information, and AIoT execution project information. As an optional implementation, the charging pile can display all information through only one display screen.

[0034] Combination Figure 1-2 As shown, in one embodiment, the charging pile further includes an image monitoring module 7, which is connected to the central control module 1. It should be noted that the image monitoring module 7 in this embodiment can be used for license plate or user recognition, or it can monitor brightness and activate infrared LEDs to ensure image monitoring when the brightness is insufficient. Furthermore, the image monitoring module 7 includes a static image acquisition device or a dynamic video acquisition device, thereby acquiring image or video information to monitor the surrounding environment of the charging pile and display it through the display module 6.

[0035] Combination Figure 1-2 As shown, in one embodiment, the charging pile further includes a power supply module 8, which is connected to the central control module 1. It should be noted that the power supply module 8 in this embodiment can provide charging services to charging pile users and can also convert mains power (or power converted from other energy sources such as solar energy) into DC power to supply power to various modules in the charging pile, such as the central control module 1, the 5G communication module 2, and the wireless local area network module 3.

[0036] Combination Figure 1-2As shown, in one embodiment, the power supply module 8 includes a DC charging module 81 and an AC charging module 82. It should be noted that the DC charging module 81 and the AC charging module 82 in this embodiment each include a charging gun and a charging cable. Furthermore, the DC charging module 81 can charge the on-board battery of an electric vehicle by outputting adjustable DC power, thereby providing fast charging services, or it can charge the batteries or independent batteries of other mechanical devices. On the other hand, the AC charging module 82 can output AC power to the on-board charger of the electric vehicle. After the on-board charger performs DC voltage regulation work such as rectification, filtering, and voltage stabilization of the AC power, it provides the regulated DC power to the electric vehicle, thereby providing slow charging services.

[0037] Combination Figure 1-2 As shown, in one embodiment, the charging pile further includes a payment module 9, which is connected to the central control module 1. It should be noted that the payment module 9 in this embodiment includes a card reader, allowing charging pile users to pay by swiping their cards based on the charging billing information displayed on the display module 6. As an optional implementation, the payment module 9 can provide payment functionality to charging pile users through other methods such as QR code payment.

[0038] Combination Figure 1-2 As shown, in one embodiment, the charging station further includes an emergency contact module 10, which is connected to the central control module 1. It should be noted that the emergency contact module 10 in this embodiment includes a call module 101 and an emergency button 102. The call module 101 can be used to contact staff, make emergency calls, or broadcast emergency messages. On the other hand, the emergency button 102 allows users to promptly notify staff in case of emergencies or accidents. Therefore, the charging station improves safety by incorporating the emergency contact module 10.

[0039] This invention provides a charging pile, which includes a central control module and a 5G communication module, a wireless local area network module, and a memory connected to the central control module. The central control module receives unicast request signals from a source base station via the 5G communication module, reserves storage space in the memory based on the unicast request signals, and sends a ready-to-receive signal to the source base station via the 5G communication module. It also receives user information to be transmitted from the source base station via the 5G communication module and stores it in the memory space. Furthermore, it forwards the user information to a user terminal or other charging piles via the 5G communication module, or forwards it to other charging piles via the wireless local area network module. Therefore, the charging pile can be used as a 5G NR multi-hop relay base station on top of existing charging functions, while saving network bandwidth consumption and power consumption of the transmitting base station.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can be modified and varied in various ways.
