Description

Technical Field

[0001] The present invention relates to the technical field of power banks, and specifically, to a shared charging cabinet for Bluetooth identification and control of a power bank and a method for using the same. Background Art

[0002] Currently, the mainstream communication method for shared charging cabinets to operate power banks is IIC. Because of the characteristics of IIC, it has been favored by the shared charging industry. However, with the diversification of the placement scenarios of shared charging cabinets, the hardware carriers for implementing IIC communication will experience IIC communication failures in specific scenarios due to their own property characteristics.

[0003] In response to such situations, there have also been some solutions in the industry, such as NFC identification, infrared identification, and other technologies. However, the following problems still exist:

[0004] 1. Reading and operating a power bank with IIC has the disadvantage that IIC communication may be poor due to factors such as dirty or rusty IIC pin points. Since the pin points are exposed, they are easily soiled or rusted.

[0005] 2. Identifying and operating a power bank with NFC has the disadvantages of short identification distance and poor later expandability due to communication distance limitations.

[0006] 3. Infrared identification has the disadvantage of relatively high hardware costs.

[0007] The existing Chinese patent with the publication number CN113963491B discloses a method for preventing the loss of rented power banks, including: a power bank, which is built-in with a Bluetooth positioning function module, sends positioning and power information externally based on the internal battery voltage and the working state of the power bank, and outputs corresponding sound effects for anti-loss alarm according to the working state of the power bank; a charging cabinet, which records the numbers of the power banks placed in or lent out of the charging cabinet, and the charging cabinet is built-in with a Bluetooth query function module for collecting the positioning and power information sent by the surrounding power banks, and sends the information to the management platform for processing according to the sound effects for anti-loss alarm output by the working state of the power bank; a mobile phone APP, which records the numbers of the power banks in use or the used power banks, records the corresponding usage time information, and collects the positioning and power information sent by the surrounding power banks through the built-in Bluetooth, and sends the collected information to the management platform for processing through the communication module of the mobile phone data network.

[0008] In the prior art, there is an operation of embedding a Bluetooth chip inside a power bank, but the application is limited to positioning and cannot perform functional operations on the power bank.

[0009] Therefore, it is necessary to provide a shared charging cabinet that can identify and control power banks via Bluetooth, which can work safely and efficiently when the communication between the cabinet and the power bank is poor, when the power bank works independently of the cabinet, and when the cellular network fails. Summary of the Invention

[0010] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a shared charging cabinet for identifying and controlling power banks via Bluetooth and its usage method.

[0011] According to a shared charging cabinet for identifying and controlling power banks via Bluetooth provided by the present invention, it includes: a cabinet and a power bank. The cabinet includes: a power supply, an MCU central control, and a bin module connected in sequence. The bin module is connected to a first Bluetooth MCU.

The first Bluetooth MCU is connected to the second Bluetooth MCU.

[0012] Preferably, the second Bluetooth MCU is programmed with a unique Bluetooth signal ID.

[0013] Preferably, the bin opening is provided with a Bluetooth trigger device. When the power bank completely enters the bin opening, the power bank switches to the broadcast mode through the Bluetooth trigger device and broadcasts Bluetooth information externally.

[0014] Preferably, a cellular communication module or a Wi-Fi module is further provided inside the cabinet.

[0015] Preferably, the power bank is further provided with an IIC module.

[0016] According to a usage method of a shared charging cabinet for identifying and controlling power banks via Bluetooth provided by the present invention, it includes the following steps:

[0017] Step S1, the user inserts a power bank into an empty bin opening of the cabinet and triggers the power bank system;

[0018] Step S2, the first Bluetooth MCU inside the cabinet scans the Bluetooth broadcast signal of the power bank in the bin opening, recognizes the appearance of a new Bluetooth broadcast signal, and initiates a connection request;

[0019] Step S3, the first Bluetooth MCU and the second Bluetooth MCU of the newly inserted power bank perform interactive authentication. If the authentication is successful, the connection is established successfully; otherwise, it is recognized and added to the blacklist;

[0020] Step S4, the cabinet sends messages, and the power bank reports information after receiving the operation control;

[0021] Step S5, the cabinet reports the read information to the cloud platform, and the cloud platform uses the data for business processing.

[0022] Preferably, in step S3, after the Bluetooth signal matching between the first Bluetooth MCU and the second Bluetooth MCU of the newly inserted power bank is completed, mutual authentication is performed through a key.

[0023] Preferably, in step S3, if the connection is successful, the hatch of the cabinet fixes the power bank through a locking device; if the connection is unsuccessful, the hatch of the cabinet ejects the power bank through an ejection device.

[0030] Figure 1 It is a communication schematic diagram of a shared charging cabinet that mainly embodies Bluetooth identification and control of a power bank according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0031] The present invention will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several changes and improvements can still be made. These all fall within the protection scope of the present invention.

[0032] Embodiment 1

[0033] As Figure 1 shown, a shared charging cabinet for Bluetooth identification and control of a power bank according to the present invention includes: a cabinet and a power bank. The cabinet includes: a power supply, an MCU central control, and a bin module connected in sequence. The bin module is connected to a first Bluetooth MCU, or the MCU central control can directly have Bluetooth-related capabilities. A plurality of bin openings for placing power banks are provided in the bin module, and a second Bluetooth MCU is provided inside any power bank. The first Bluetooth MCU is connected to the second Bluetooth MCU.

[0034] The second Bluetooth MCU is burned with a unique Bluetooth signal ID.

[0035] A Bluetooth trigger device is provided at the bin opening. When the power bank completely enters the bin opening, the power bank switches to the broadcast mode through the Bluetooth trigger device and broadcasts Bluetooth information externally.

[0036] A cellular communication module or a Wi-Fi module is also provided inside the cabinet. The cabinet can transmit information through Bluetooth or through cellular or Wi-Fi.

[0037] The power bank is also provided with an IIC module. The structure of the power bank includes a structural member, a battery cell, and a main board. The main board central control supports Bluetooth-related functions, and the power bank supports IIC and Bluetooth for information transmission.

[0038] The cabinet and the power bank can be the master and slave terminals respectively for Bluetooth connection communication. After establishing a stable Bluetooth communication channel, data exchange can be performed according to a custom Bluetooth service protocol, so as to realize the ability to control the power bank through Bluetooth operation.

[0039] The Bluetooth communication link between the cabinet and the power bank is as follows: The cabinet Bluetooth switches to the scanning mode to scan the nearby Bluetooth signals. The power bank is burned with a unique Bluetooth signal ID inside, and the power bank switches to the broadcast mode to broadcast Bluetooth information externally. When the scanning and broadcast signals match, the custom key information is mutually exchanged to complete the key authentication of the communication process. After the authentication is completed, the connection is established. The communication process between the cabinet and the power bank is a custom encryption algorithm for transmitting symmetric encrypted information. At the same time, it has a reconnection strategy. When the connection is disconnected, the reconnection strategy will be started, and the number of reconnection times can be adjusted at an idempotent interval. If the message is illegal during the transmission process, the connection will be actively disconnected and there is a blacklist mechanism.

[0040] By adopting a cabinet machine and a power bank that support Bluetooth communication, this application solves the problem that when other communication methods are poor, the shared cabinet machine and the power bank cannot read and operate the power bank.

[0041] The power bank of this application supports Bluetooth communication, which solves the problem that when the power bank works independently of the cabinet machine, information cannot be read and operations cannot be performed.

[0042] The cabinet machine of this application supports Bluetooth communication, which solves the problem that when the cellular network fails, the cabinet machine cannot be operated.

[0043] The cabinet machine of this application supports Bluetooth communication, which solves the problem that the cabinet machine cannot scan the Bluetooth information of surrounding devices and connect to them.

[0044] By adopting a shared charging cabinet machine and a power bank that support Bluetooth functions, this application can complete operations on the cabinet machine, charging operations, mutual control between the cabinet machine and the charger, and mutual control between Bluetooth devices and the cabinet machine and the charger through the Bluetooth channel. While ensuring high security, various functional operations can be achieved with low-cost and low-power hardware. Moreover, Bluetooth communication has strong anti-interference ability, can maintain high stability and reliability in complex environments, reduce signal interruption and data loss, and can also achieve fast data transmission.

[0045] Embodiment 2

[0046] Based on Embodiment 1, a method for using a shared charging cabinet machine for Bluetooth identification and control of a power bank provided by the present invention, specifically an operation method for returning the power bank, includes the following steps:

[0047] Step S1, the user inserts a power bank into an empty compartment of the cabinet machine and triggers the hook system to fix the power bank;

[0048] Step S2, the first Bluetooth MCU in the cabinet machine scans the Bluetooth broadcast signal of the power bank in the compartment, recognizes the appearance of a new Bluetooth broadcast signal, and initiates a connection request;

[0049] Step S3, the first Bluetooth MCU and the second Bluetooth MCU of the newly inserted power bank perform interactive authentication. If the authentication is successful, the connection is established successfully; otherwise, it is recognized and added to the blacklist;

[0050] Step S4, the cabinet machine sends a message, and the power bank reports information after receiving the operation control;

[0051] Step S5, the cabinet machine reports the read information to the cloud platform, and the cloud platform can flexibly use the data for business processing.

[0052] More specifically, in step S3, after the Bluetooth signal matching between the first Bluetooth MCU and the second Bluetooth MCU of the newly inserted power bank is completed, mutual authentication is performed through custom key information.

[0053] In step S3, if the connection is successful, the bin opening of the cabinet fixes the power bank through the locking device; if the connection is unsuccessful, the bin opening of the cabinet ejects the power bank through the ejection device.

[0054] In step S4, the cabinet issues messages after encrypting them through a symmetric encryption algorithm using custom instructions. After receiving the operation control, the power bank can report information such as status and power, and can also perform functional operations such as charging and discharging. Generally, the commonly used symmetric encryption algorithm is the AES algorithm, which has high efficiency and security. The different key lengths determine the number of rounds in the encryption process. The more rounds, the higher the security. It has been widely used in various scenarios, including network communication, file encryption, database protection, etc. Due to its inherent strength, it is extremely difficult to crack AES encryption unless there are serious implementation errors or improper use.

[0055] The cabinet has a reconnection strategy. When the connection is disconnected, the reconnection strategy will be started. The number of reconnection attempts can be adjusted at an idempotent interval. If an illegal message is detected during the transmission process, the connection will be actively disconnected and the device will be added to the blacklist.

[0056] Furthermore, the shared charging cabinet for Bluetooth identification and control of the power bank in this application can also complete operations on the cabinet, charging operations, mutual control between the cabinet and the charger, and mutual control between Bluetooth devices and the cabinet and the charger through the Bluetooth channel.

[0057] In the description of this application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to this application.

[0058] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which does not affect the essence of the present invention.
