Description

Technical Field

[0001] The present invention relates to the field of RFID technology, and particularly to a method, a system and a storage medium for centralized charging management of electric bicycle batteries based on RFID. Background Art

[0002] In recent years, there have been an increasing number of spontaneous combustion and fire accidents caused by electric bicycles. Although local laws and regulations have made strict regulations on the problem of electric bicycles going upstairs, there are still problems with difficult management. Therefore, it is necessary to adopt certain technical means to cooperate with laws and regulations to achieve effective management of electric bicycles.

[0003] Data shows that 80% of the spontaneous combustion and fire accidents caused by electric bicycles occur during the charging process. The source of the fire is the battery of the electric bicycle, rather than the body of the electric bicycle. Carrying only the battery into the household for charging will still cause accidents. Therefore, the key to managing electric bicycles lies in controlling the battery and preventing users from carrying the battery into the household for charging. However, the existing methods lack real-time identification and mandatory control solutions for the battery charging environment, and cannot eliminate the potential safety hazards of battery charging into the household from the source. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a method, a system and a storage medium for centralized charging management of electric bicycle batteries based on RFID, so as to achieve safe centralized charging of electric bicycle batteries and prevent the fire risk caused by users' illegal charging into the household.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] The RFID reader communicates with the RFID tag in the battery.

[0009] After successful communication, the battery is activated once every 1 minute. When it is confirmed that the battery is in the activated state, the battery can continue to be charged.

[0010] When the RFID tag does not receive the signal from the RFID reader within the set time period, the battery enters the deactivated state, the charging circuit is disconnected, and the charging stops.

[0011] In the present invention, preferably, the interior of the battery includes a battery cell, a charging circuit, a relay, and a driving circuit.

[0014] In the present invention, preferably, the RFID reader includes a second processor and a second radio frequency transceiver. The second radio frequency transceiver is connected to a second antenna, and data communication with the RFID tag is achieved through the second antenna.

[0015] In the present invention, preferably, after the RFID tag establishes communication with the RFID reader, the RFID reader sends an activation signal to the RFID tag.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0030] Please refer to Figure 1 , a preferred embodiment of the present invention provides a method for centralized charging management of electric bicycle batteries based on RFID, including the steps of:

[0031] Put the battery with an embedded RFID tag into the charging cabinet with an embedded RFID reader;

[0032] The RFID reader communicates with the RFID tag inside the battery;

[0033] When the communication is successful, the battery is activated once every 1 minute. When the battery is confirmed to be in the activated state, the battery can continue to be charged;

[0034] When the RFID tag does not receive any signal from the RFID reader within a set time period, the battery enters a deactivated state, disconnects the charging circuit, and stops charging.

[0035] Specifically, the battery needs to be placed in a matching charging cabinet for use, that is, when the battery needs to be charged, it is placed in a specific charging cabinet. Each charging compartment in the charging cabinet is equipped with an RFID reader, and the battery has a built-in RFID tag. When the RFID reader in the charging cabinet successfully communicates with the RFID tag of the battery placed in it, the RFID reader sends an activation signal to the RFID tag once every 1 minute. After the RFID tag receives the activation signal, its internal charging circuit is connected to charge the battery. When the RFID tag is connected for 5 minutes without receiving the activation signal sent by the RFID reader, it is determined that the battery has been removed from the charging cabinet, the battery enters the deactivated state, the charging circuit is disconnected, and the charging ends. The battery can only be activated for charging if it is placed in a matching charging cabinet. If it is not placed in a charging cabinet, the charging circuit cannot be activated, and charging cannot be performed, thereby ensuring that the battery is charged at the designated location, eliminating the safety hazards of battery charging at home from the source, and is safer and more reliable than other legal management methods.

[0036] In this embodiment, the battery includes a battery cell, a charging circuit, a relay and a drive circuit. The drive circuit is electrically connected to the relay, the relay is connected between the live wire and the charging circuit, and the charging circuit is electrically connected to the battery cell.

[0037] In this embodiment, the normally open end of the relay is connected to the live wire of the input end, the common end is connected to the charging circuit through a controlled live wire, and the charging circuit is also connected to the neutral wire of the charging end. When the RFID tag establishes communication with the RFID reader, the RFID reader sends an activation signal to the RFID tag, and the RFID tag controls the normally open end of the relay to close through the driving circuit after receiving the activation signal, so that the relay is powered on and the battery cell is charged through the charging circuit.

[0038] In this embodiment, the RFID tag includes a first processor, a first radio frequency transceiver, and a first antenna connected together, and the processor is electrically connected to the driving circuit.

[0039] In this embodiment, the RFID reader includes a second processor and a second radio frequency transceiver, the second radio frequency transceiver is connected to a second antenna, and data communication with the RFID tag is achieved through the second antenna. In this application scenario, since each grid of the charging cabinet is made of metal, it naturally has a good shielding effect, which can effectively avoid misreading the RFID tags of batteries in other grids, and the technical implementation is easier.

[0040] See also Figure 2 , an electric bicycle battery centralized charging management system based on RFID technology, including

[0041] A battery, wherein the battery has a built-in RFID tag, a drive circuit, a relay, a charging circuit and a battery cell, and the drive circuit is connected between the RFID tag and the relay;

[0042] The charging cabinet includes multiple charging grids, each of which has an internal RFID reader. The RFID reader includes a processor, a radio frequency transceiver and an antenna for communicating with the RFID tag and sending an activation signal. The charging grid adopts a stainless steel metal cavity with a ferrite absorbing layer on the inner wall. The metal grid forms an electromagnetic shielding space (shielding effectiveness ≥ 20dB) to ensure the isolation of tag signals between adjacent charging grids.

[0043] The power module is connected to the charging cabinet module, adopts a switching power supply architecture, has overvoltage protection, overcurrent protection and temperature compensation functions, and is used to provide power for the charging circuit.

[0044] The RFID tag includes a first processor, a first radio frequency transceiver and a first antenna. The first antenna adopts an inverted F-shaped metal structure and is fixed to the inner side of the battery housing by adhesive. The distance between the first antenna and the metal housing is ≥5mm to avoid signal attenuation. The RFID reader includes a second processor and a second radio frequency transceiver. The second radio frequency transceiver is connected to a second antenna. The antenna is used to collect and send radio frequency signals. The radio frequency transceiver is used to modulate the baseband signal into a radio frequency signal or demodulate the radio frequency signal into a baseband signal and send it to the processor. The processor is used to process the baseband signal to realize information interaction between the RFID reader and the RFID tag.

[0045] The normally open end of the relay is connected to the charging live wire, and the common end is connected to the charging circuit through the controlled live wire. The RFID tag controls a relay through a driving circuit, and the relay is connected in series to the charging live wire through the normally open end and the common end to realize the control of the charging power supply.

[0046] Specifically, after the battery is placed in the charging cabinet, the relay in the battery is in the normally open state, the live wire is disconnected, and the charging cabinet cannot charge the battery. At this time, the RFID reader starts to work and sends an activation command every 1 minute to communicate with the RFID tag. When the RFID tag receives the activation command, it controls the relay through the drive circuit to make the relay in the closed state for 5 minutes. At this time, the relay is powered on and can charge the battery;

[0047] Within 5 minutes, if the RFID tag receives the activation command from the RFID reader again, the charging time can be reset to 5 minutes. As long as the battery remains in the charging cabinet, the charging process will not be affected. After charging is completed, the battery is taken out. When leaving the charging cabinet, the RFID tag in the battery cannot receive the activation command, and the relay will be disconnected, so charging cannot continue.

[0048] In some other preferred embodiments of the present invention, a computer-readable storage medium is provided, storing a computer program, which when executed by a processor, causes the processor to execute the steps of the method as described in the above embodiments.

[0049] If the above functions are implemented in the form of software function units and sold or used as independent products, they can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, or a part of this technical solution, can be embodied in the form of a software product. This computer software product is stored in a storage medium and includes several instructions to cause a computer device (which can be a personal computer, a server, or a network device, etc.) to execute all or part of the steps of the methods described in various embodiments of the present invention. The foregoing storage medium includes: various media such as USB flash drives, mobile hard disks, read-only memories (ROM, Read-Only Memory), random access memories (RAM, Random Access Memory), magnetic disks, or optical discs that can store program codes.

[0050] The above description is a detailed description of the preferred and feasible embodiments of the present invention, but the embodiments are not used to limit the patent application scope of the present invention. Any equivalent changes or modifications made under the technical spirit disclosed by the present invention shall fall within the patent scope covered by the present invention.
