Detailed implementation manners

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0036] Intelligent Internet of Things refers to a technical field that realizes the interconnection and interoperability between items through Internet of Things technology, enabling items to automatically sense, automatically identify, automatically interact, and automatically control. This field involves multiple disciplines such as computer science, communication engineering, and electronic engineering, aiming to achieve the intelligence and automation between items through technical means. The electric bicycle shared battery swapping cabinet with all-net-communication technology is an application in the field of intelligent Internet of Things. It uses all-net-communication technology to realize the remote monitoring and management of equipment, improving the use efficiency and safety of the electric bicycle shared battery swapping cabinet. In colleges and universities, the electric bicycle shared battery swapping cabinet also belongs to the field of smart campus construction. Therefore, the shared battery swapping cabinet can well solve the charging safety problem of the public when using electric bicycles for travel in the current fast-paced life, and improve the use experience and user satisfaction of the shared battery swapping cabinet.

[0037] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0038] In an exemplary embodiment, as Figure 1 shown, there is provided an all-net-communication-based smart campus electric bicycle shared battery swapping cabinet, including: cabinet body 1, power supply 2, emergency isolation device 3, communication module 4, control module 5, and multiple battery compartments 9. Among them, the control module 5 is an embedded computer.

[0039] As Figure 2As shown, the cabinet body 1 is used to support the battery compartment 9. The battery compartment 9 is used to accommodate the power battery of the electric bicycle. A battery compartment door 8 is provided on the battery compartment 9. The power supply 2 is used to supply power to the power battery in the battery compartment 9. The communication module 4 is used to communicate with a user terminal (such as a mobile phone) by means of full-netcom cellular communication. The control module 5 is used to detect the state of the power battery in the battery compartment 9 in real time, and when the power battery is in a critical dangerous state, control the emergency isolation device 3 to isolate the corresponding battery compartment 9.

[0040] In a specific application example, the battery compartment 9 is a separable compartment, which is composed of a cuboid compartment with a single-sided opening. An explosion-proof bag made of Kevlar fiber is pasted on the inner wall of the cuboid compartment section.

[0041] In a specific application example, the power supply 2 is an uninterruptible power supply. The power supply 2 includes an external AC power supply and a storage battery. The control module 5 is further used to detect the connection state of the external AC power supply in real time. When the external AC power supply is powered on, control the external AC power supply to supply power to the power battery and the storage battery. After the external AC power supply is powered off, control the storage battery to supply power to the power battery.

[0042] Currently, the power supply of the current battery swapping cabinet usually uses the power supply of a local community or company unit close to the location of the battery swapping cabinet. Such power supplies are usually not well managed and there is a risk of accidental power outage. And once such battery swapping cabinets with a power outage risk form user dependence, it will greatly affect the user experience.

[0043] Therefore, this application uses an uninterruptible power supply technology with a storage battery as the core. The uninterruptible power supply technology uses a power battery with high energy storage and high discharge rate as the energy storage basis. Such storage batteries can be sourced from discarded automotive power battery packs and other industry-discarded energy storage battery packs. When the external AC power supply is powered off, the storage battery can supply auxiliary power to the battery swapping cabinet. After the external AC power supply resumes power supply, the storage battery switches to the charging state. After the storage battery is fully charged, it can be in the standby state or supply power to the battery swapping cabinet during peak electricity consumption periods, thereby reducing the operating cost for the battery swapping cabinet operator.

[0044] When deploying a battery swapping cabinet in an area where the commercial electricity price is high during the day and low at night, the storage battery can be configured to supply power to the battery swapping cabinet during the day and be powered by the external AC power supply at night and be charged, so as to effectively control the energy consumption cost.

[0045] The embedded computer is connected to the control interface of Power Supply 2 through a Universal Asynchronous Receiver / Transmitter (UART) interface, and can control and switch the working state of Power Supply 2. At the same time, Power Supply 2 also sends its working state to the embedded computer through the UART interface. Specifically, as Figure 3 shown. First, the uninterruptible power supply is initialized. Then, the embedded computer detects the power state of the energy storage battery. When the energy storage battery is not fully charged, the charging mode is started. When the energy storage battery is fully charged, it waits to receive control instructions. The embedded computer can send control commands to the uninterruptible power supply. The control commands include "uninterruptible power supply standby mode", "direct power supply mode of the energy storage battery", and "charging mode". Among them, the "uninterruptible power supply standby mode" means that when the battery replacement cabinet uses an external AC power supply, the energy storage battery is in a standby state and can be immediately connected to the power supply when the external AC power supply is cut off, so as to ensure the continuous operation of the battery replacement cabinet; the "direct power supply mode of the energy storage battery" is to directly use the electric energy in the energy storage battery to supply power to the battery replacement cabinet, while the external AC power supply will be cut off; the "charging mode" is that the battery replacement cabinet uses an external AC power supply and at the same time uses the external AC power supply to charge the energy storage battery.

[0046] In a specific application example, the emergency isolation device 3 includes: a slide rail, a grasping structure, and an explosion-proof barrel 10. The slide rail is arranged outside the cabinet body 1 and is located between adjacent battery compartments 9. The grasping structure is used to take out the corresponding battery compartment 9 under the control of the control module 5 and place it into the explosion-proof barrel 10 through the slide rail. As Figure 4 shown, the explosion-proof barrel 10 is adjacent to the cabinet body back panel 11.

[0047] Specifically, as Figures 5 to 7 shown, the emergency isolation device 3 is located on the back 12 of the battery compartment. The slide rail includes a horizontal slide rail 13 and a vertical slide rail 15. A horizontal slider 14 is arranged on the horizontal slide rail 13, and a vertical slider 16 is arranged on the vertical slide rail 15. The grasping structure includes a conveyor belt 17 and a driving motor. The driving motor is located on the conveyor belt roller 18. The conveyor belt 17 roller is located on the horizontal slide rail bearing platform 19. The conveyor belt 17 is provided with grasping barbs 20. The bottom of the battery compartment 9 is provided with barb grasping grooves 21. The driving motor is used to drive the conveyor belt 17 to move on the horizontal slide rail 13 and the vertical slide rail 15 under the control of the control module 5, so as to place the corresponding battery compartment 9 into the explosion-proof barrel 10 through the grasping barbs 20 and the barb grasping grooves 21.

[0048] The present application provides a track composed of a vertical slide rail 15 at the rear of all battery compartments 9, and a transverse slide rail 13 is installed on the vertical slider 16, and a flexible slide is provided on the transverse slider 14, and the flexible slide is installed on the transverse slider 14 through a bracket, and the slide entrance faces the battery compartment 9, and the slide entrance is square, and the four sides are parallel to the battery compartment 9, and two rubber wheels driven by a driving motor and a synchronous belt are respectively provided on the four sides of the entrance, and the rubber wheels can be positioned at the rear of each battery compartment 9 under the positioning of the transverse slide rail 13 and the vertical slide rail 15. At this time, the driving motor is started, and under the transmission of the synchronous belt, the rubber wheel can suck out the battery compartment 9, and then the battery compartment 9 slides into the explosion-proof barrel 10 along the flexible slide.

[0049] The explosion-proof barrel 10 is located at the rear of the cabinet 1, and the entrance of the explosion-proof barrel 10 is located below the back plate of the cabinet 1 shell. The battery compartment 9 loaded with dangerous critical state batteries will slide into the explosion-proof barrel 10 from the hole. The hole is designed for one-way passage. When the dangerous critical battery deflagrates or explodes, this one-way hole can prevent high-temperature gas or solid matter from passing through, thereby protecting the safety of the battery in the battery swap cabinet and avoiding the harm of the dangerous critical state battery to the surrounding environment and others.

[0050] Conventional battery swap cabinets usually use a simple iron box, a controllable door and a charging system distributed in each box. The charging systems in each box can be integrated or independent of each other. Traditional electric motorcycle batteries are charged and discharged in a single cycle, such as Figure 8 As shown, the power battery is discharged during the riding of the motorcycle, and the battery is charged when the power battery is insufficient. After the charging is completed, the battery is undercharged or overcharged. There is no safety monitoring system for lithium-ion power batteries with higher energy density, and it is impossible to monitor the uncontrollable and unsafe factors of the power battery during the charging process. If the conventional motorcycle battery swap cabinet is charging the motorcycle battery at full load, once the lithium-ion power battery is in a dangerous critical state, the conventional battery swap cabinet cannot identify it and physically isolate it in the first time. The dangerous critical state is the possible explosion state of the lithium-ion power battery with volume expansion, gas leakage, smoke and sudden volume change. Therefore, once a lithium-ion power battery explodes in a conventional motorcycle battery swap cabinet, it can be foreseen that the explosive battery will burn through the iron sheet of the box with its high temperature, and then trigger a series of lithium-ion battery explosions, and even ignite surrounding combustibles, and cause burns to people around.

[0051] When the embedded computer detects that a power battery in a battery compartment 9 is smoking, hot, and the battery packaging structure is deformed, the power battery is determined to be in a critical state. The power battery in a critical state will be taken out from the rear of the cabinet 1 together with the battery compartment by the grasping structure and placed in the explosion-proof barrel 10 located at the rear of the cabinet 1, thereby eliminating the dangerous factors and ensuring the safety of other power batteries.

[0052] In a specific application example, the communication module 4 includes a full-net 5G communication module and a WiFi communication module. Among them, the full-net 5G communication module includes multiple eSIM chips, and each eSIM chip is correspondingly connected to a cellular network.

[0053] The intelligent campus electric bicycle sharing battery swapping cabinet provided by this application is equipped with a full-net 5G communication module based on the eSIM cellular network and a WiFi6 communication module. The communication module 4 is used to connect the cellular networks of multiple operators, providing network access of multiple operators for the battery swapping cabinet, so as to ensure the smooth network of the battery swapping cabinet.

[0054] At present, most of the existing battery swapping cabinets rely on the network supply of a single location, such as relying on the Internet of Things network of local surrounding communities or the network of surrounding companies; the network used by the electric bicycle battery swapping cabinet based on such network supply may be unstable or congested during a certain period, which is likely to cause the battery swapping cabinet to be unable to connect to the remote server normally and unable to provide battery swapping services for surrounding users normally. In addition, due to the unstable cellular network signal at some locations, there is still a phenomenon that the battery swapping cabinet equipped with the traditional cellular Internet of Things cannot connect to the network normally.

[0055] Therefore, this application uses a full-net 5G communication module and a WiFi6 communication module that simultaneously carry three eSIM chips. The full-net cellular communication method simultaneously adopts the 5G cellular networks and technologies of China Mobile, China Unicom, and China Telecom, and uses the over-the-air card writing technology of eSIM chips to write the operator card opening information into the eSIM chips at any time. When the battery swapping cabinet is deployed at any location, it can access the network according to the local cellular network coverage. During use, if any less than 2 cellular networks cannot cover a node of any battery swapping cabinet, or the network rate is low or the network is congested, the available cellular network of the operator can be automatically replaced at any time. That is, the networks of different operators corresponding to the three eSIM chips are mutually backed up, which can greatly improve the reliability of the network.

[0056] When the battery swapping cabinet is deployed between buildings or at a bridge location with many obstacles, due to physical obstruction, the eSIM cellular network signal is poor or even does not have the network connection ability, the WiFi6 communication module can connect to the WiFi network provided by the nearby operator.

[0057] The embedded computer is connected to the communication module 4 through the Peripheral Component Interconnect Express (PCIe) bus. The embedded computer can send control instructions to the communication module 4 through the PCIe bus, and the communication module 4 will send its working status to the embedded computer, while completing the reception and transmission of network data. The embedded computer can perform timely switching according to the local cellular network coverage and the network switching algorithm to ensure smooth network connection.

[0058] As Figure 9 shown, first, initialize the network, and then perform the network connection status detection of three eSIM chips and the WiFi6 communication module in parallel (including judging whether to connect to the network, performing network speed measurement, and judging whether the network speed meets the requirements). When the network speed of the eSIM chip meets the requirements, perform the cellular network status detection. If any two of the three cellular networks have normal status, perform network connection and prepare for data reception and transmission. When the network speed of the WiFi6 communication module meets the requirements, prepare for network connection and use it as a backup network, perform network connection and prepare for data reception and transmission.

[0059] In another exemplary embodiment, the intelligent campus electric bicycle sharing battery swapping cabinet based on the all-netcom also includes a touch display screen 6. The touch display screen 6 is located on the surface of the cabinet body 1, and the touch display screen 6 is used for human-computer interaction with users.

[0060] The embedded computer is connected to the touch display screen 6 through the Mobile Industry Processor Interface (MIPI) and the Display Serial Interface (DSI). The touch display screen 6 is connected to the embedded computer through the I2C bus. The embedded computer sends the graphical interface to be displayed to the touch display screen 6 through the MIPI DSI interface, and receives the human-computer operation instructions from the user through the touch display screen 6.

[0061] During the working process, the touch display screen 6 displays the user operation interface, receives the display content sent by the embedded computer, and performs display. The touch display screen 6 can receive the interactive instructions selected or input by the user to assist the user in completing operations such as verification login and opening the box.

[0062] In another exemplary embodiment, the all-netcom-based intelligent campus electric bicycle sharing battery swapping cabinet further includes a Beidou satellite positioning module 7. The Beidou satellite positioning module 7 is used to obtain the positioning data and timing data of the cabinet body 1 in real time. The Beidou satellite positioning module 7 is a Beidou satellite navigation receiving antenna. The Beidou satellite positioning module 7 is integrated on an embedded computer, which is mainly used to connect to the Beidou satellite network, so as to obtain accurate positioning data and timing data, and then assist users to quickly find the battery swapping cabinet.

[0063] The embedded computer is connected to the Beidou satellite navigation receiving antenna through the UART interface to receive the positioning data and timing data from the Beidou satellite.

[0064] As Figure 10 shown, after the all-netcom-based intelligent campus electric bicycle sharing battery swapping cabinet provided by this application is started, the embedded computer is first started, and the embedded computer initializes the touch display screen 6, so as to complete the display of the graphical interface and prepare for touch operations; then start to initialize each functional module, including the Beidou satellite positioning antenna, the communication module 4, the emergency isolation device 3 and the power supply 2. When it is confirmed that each functional module is working properly, first call the Beidou satellite positioning antenna to obtain positioning data and timing data through the Beidou satellite, and then enter the Figure 9 shown cellular network switching process and Figure 3 shown power supply 2 status switching process to connect to the cellular network and control the power supply 2. After the above operations are completed, the shared battery swapping cabinet is started to the operating state and waits for users to use. The process for users to swap batteries is as follows: Users operate the power battery of the electric bicycle for lending through the mobile application or the touch display screen 6 of the shared battery swapping cabinet. The shared battery swapping cabinet manages the power battery that is being used for lending. After the user finishes using, through mobile phone operation, the power battery is returned to the shared battery swapping cabinet. The shared battery swapping cabinet will open an empty battery compartment 9, and the user places the power battery into the battery compartment 9 of the shared battery swapping cabinet. The battery compartment 9 will automatically connect to the charging interface of the power battery to charge and manage it. At the same time, the power battery being charged is detected. If the power battery is in a dangerous critical state, the grasping structure is called to place the power battery into the explosion-proof barrel 10. After the power battery is fully charged, the shared battery swapping cabinet sets its status to available and waits for other users to use.

[0065] The intelligent campus electric bicycle shared battery swapping cabinet based on full-network communication provided by this application includes a full-network communication 5G communication module and a WiFi communication module, which can simultaneously connect to the cellular networks of multiple operators to improve the stability of the battery swapping cabinet. Moreover, it is equipped with an emergency isolation device 3, which can take out the power battery in a dangerous critical state through a mechanical grasping mechanism, thus avoiding uncontrollable battery combustion and explosion. It is equipped with an uninterruptible power supply, which can provide uninterrupted power supply for the battery swapping cabinet, and can also supply power to the battery swapping cabinet during periods of high electricity prices and charge during periods of low electricity prices, thereby reducing the operating cost of the battery swapping cabinet.

[0066] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0067] Specific examples are used in this article to elaborate on the principle and implementation manner of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application; at the same time, for those of ordinary skill in the art, according to the idea of this application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to this application.
