[0039] Embodiment one:

[0040] Reference Figure 1 An intelligent battery replacement cabinet based on RFID battery replacement mode, comprising a cabinet body 1, a plurality of battery storage compartments 2, an RFID card reading device 3, a control unit and a power supply system.

[0041] The cabinet body 1 is a hollow protective shell, which adopts a protective shell made of metal material, such as cold-rolled steel plate. The surface of the cabinet body 1 is treated for rust prevention (such as plastic spraying). The inside of the cabinet body 1 can also be provided with heat dissipation holes, such as a honeycomb-shaped heat dissipation opening on the back of the cabinet body 1.

[0042] A plurality of battery storage compartments 2 are fixedly installed inside the cabinet body 1. The battery storage compartments 2 are arranged in the cabinet according to a 4x4 matrix. The size of each storage compartment is suitable for standard batteries (such as 20cm long x 15cm wide x 30cm high). The inner wall of the battery storage compartment 2 is provided with an insulating layer (such as a PVC plate) to prevent short circuit of the battery 4. Each battery storage compartment 2 is provided with an openable and closable cabinet door. The cabinet door is electrically connected to the control unit through a cabinet door driving mechanism.

[0043] The RFID card reading device 3 is installed at the lower position of the front side panel of the cabinet body 1, such as 1.2 meters from the ground, which is convenient for the user to hold the battery close; wherein the RFID card reading device 3 is built-in MFRC522 chip, and the card reading antenna is a ring-shaped copper coil, which is tuned with the chip through a 100pF matching capacitor, and can emit a 13.56MHz radio frequency signal, forming a hemispherical RFID card reading area (the opening faces the user operation surface) with the antenna installation position as the center and a radius of 0.5 meters in front of the cabinet body 1. When the RFID card strip 5 installed on the side of the battery 4 enters the hemispherical area, the RFID card strip 5 obtains energy (the rectified induced voltage supplies power to the card strip chip) from the radio frequency signal through electromagnetic induction principle and activates, and transmits the stored user ID, battery ID and other information back to the card reading device through load modulation (changing the impedance of the card strip antenna), and then the MFRC522 chip demodulates and transmits to the control unit through the SPI interface, realizing wireless reading of the battery information.

[0044] The control unit is electrically connected with the RFID card reading device 3, and the control unit is built-in STM32 microcontroller and local storage module (such as EEPROM chip), the local storage module pre-stores user information database, including user ID, account status and battery information database, including battery ID, power threshold; the control unit performs user identity verification and battery matching in the local database based on the information of the read RFID card strip 5, and if the verification is passed and there is an available battery 4, the cabinet door opening of the corresponding battery storage compartment 2 is controlled through the cabinet door driving mechanism.

[0045] The power supply system provides power support for each component of the intelligent battery replacement cabinet, wherein the power supply system connects the mains through an AC220V to DC12V power adapter (60W), outputs 12V direct current to power the cabinet door driving mechanism, and after voltage stabilization, powers the control unit, card reading device and other low-voltage components; matched with 12V / 2Ah backup lithium battery, automatically switches power supply when power failure, supports the continuous operation of the battery replacement cabinet for 30 minutes, and guarantees the stable power consumption of each component.

[0046] Reference Figure 2 On the side surface of the outer periphery except the top and bottom of the battery 4, the RFID card strip 5 is fixedly connected, and the RFID card strip 5 stores the user ID identification and the ID identification of the battery 4. Among them, the RFID card strip 5 and the battery 4 are fixedly connected in a gluing or embedding manner, such as being glued by 3MVHB (temperature resistance-40℃~150℃), or the battery 4 is embedded with a card strip by setting a groove (1mm deep, 5cm long, 2cm wide) on the side surface. The surface of the RFID card strip 5 is covered with a PET protective film (0.1mm thick), which is waterproof and scratch-resistant.

[0047] The local storage module is arranged in the control unit, and is used for pre-storing a user information database and a battery information database, so as to realize identity authentication and battery 4 matching in a network environment, expand the applicable scenarios of the battery swap cabinet, ensure the battery swap process is not interrupted in a poor network signal area or a remote area, temporarily store the battery swap record (such as time, user ID and battery ID) in the local storage, and upload the battery swap record after the network is restored, and guarantee the data integrity. The local storage module adopts an AT24C02 EEPROM chip (storage capacity: 256 bytes) or a W25Q64 Flash chip (storage capacity: 8 MB), and supports 100,000 times of erasing and writing. The user information database includes identification information associated with the user identity, such as a user ID, an account state (normal / frozen), an account balance and the like. The battery information database includes basic information of the battery, such as a model, a power, a use state, a production batch and the like. In addition, a USB interface reserved in the cabinet 1 is used for connecting a computer, and the local database is manually updated. A data encryption chip can be further added to encrypt the data stored in the local storage.

[0048] The cabinet 1 is provided with a prompt module including indicator lights 6 and a loudspeaker 7. The prompt module adopts shielded twisted pair wires, one end of which is welded to the terminal of the indicator lights 6 and the loudspeaker 7, and the other end is plugged into the mainboard of the control unit through an RJ45 interface, and is electrically connected with the control unit. The cabinet door opening position and the operation state are prompted by light or voice. The indicator lights 6 are RGB three-color LEDs embedded in the front surface of the cabinet 1, and different colors are used to prompt different states of the user, such as green constant light indicating that the cabinet door is opened, red flickering indicating that the authentication fails, and yellow slow flickering indicating that the data is uploading. The loudspeaker 7 is fixed in the reserved mounting hole at the top of the cabinet 1 by a bolt, and a rubber gasket is arranged between the bolt and the mounting hole to reduce vibration and noise. The loudspeaker 7 cooperates with the voice module to synthesize voice prompts in real time according to system instructions, for example, a SYN6288 voice module (supporting text-to-speech (TTS) function). In the scenario where the identity authentication is passed, when the RFID card reading area detects a legal battery and the system authentication is passed, the loudspeaker 7 will broadcast the voice “authentication success, please take out the Xth battery” (X is the battery position number).

[0049] Reference Figure 4 The trigger process of the prompt module is as follows: when the user places the battery 4 in the RFID card reading area, if the identity authentication is passed, the control unit sends a pulse signal to the indicator lights 6 through the signal line, drives the indicator lights 6 to flash green light at a frequency of 2 Hz, and at the same time, the loudspeaker 7 plays the voice “please take out the Xth battery”. If the identity authentication fails, the control unit drives all the indicator lights 6 to be always on red, and the loudspeaker 7 plays the voice “authentication failure, please place the battery again”. When the user closes the cabinet door, the indicator lights 6 are extinguished, and the loudspeaker 7 plays “operation completed”.

[0050] The cabinet door driving mechanism is integrated in the intelligent battery replacement cabinet cabinet body 1, and is flexibly deployed according to the structural difference of the battery storage compartment 2. For example, the driving mechanism of the side-opening door type storage compartment is usually installed on the side of the cabinet door and cooperates with the hinge, guide rail and other components; the driving mechanism of the drawer type storage compartment is arranged at the bottom or side of the corresponding drawer of the cabinet body 1 to realize stable push-pull control.

[0051] The cabinet door driving mechanism generally consists of a power component and a transmission component. The power component adopts a DC motor, a stepping motor or the like to provide a power source for the operation of the mechanism. The transmission component includes gear, belt, screw and other components for transmitting and converting power. Taking gear transmission as an example, the rotation of the motor is transmitted to the cabinet door connecting component through gear meshing; the screw transmission converts the rotation of the motor into linear motion to accurately drive the cabinet door to move. In addition, the driving mechanism is also provided with a damper and other buffer devices to slow down the closing speed of the cabinet door, reduce the impact force, effectively protect the cabinet door and the cabinet body 1, and reduce noise.

[0052] The working process of the cabinet door driving mechanism is as follows: first, instruction receiving. The control unit as the core of the system is connected with the cabinet door driving mechanism through a signal line. When the RFID card reading device 3 completes information collection, and the control unit verifies the user identity and matches the battery successfully, the cabinet door opening instruction is sent to the driving mechanism; then driving execution. After receiving the instruction, the control circuit of the driving mechanism starts the power component (motor) and drives the cabinet door to open through the transmission component. If an electromagnetic lock is used as a locking component, the control unit controls its on-off state (power-on locking, power-off unlocking) to cooperate with the transmission component to realize the opening and closing operation of the cabinet door; finally, state feedback and closed-loop control. When the user completes the battery replacement and closes the cabinet door, the limit switch installed on the cabinet door or the cabinet body 1 is triggered to feed back the cabinet door closing signal to the control unit, and the control unit sends an instruction accordingly. The driving mechanism executes automatic reset or locking action to ensure the stable closing of the cabinet door.

[0053] It also includes a communication module, such as a 4G / Wi-Fi module. The communication module is arranged in the cabinet body 1 and electrically connected with the control unit. When there is no network, the battery replacement record is temporarily stored in the local storage module. When the network is restored, the temporarily stored data (such as battery replacement time, user ID, and battery ID) is automatically uploaded to the server to realize cloud synchronization of the battery replacement data, support the remote monitoring of the battery replacement cabinet state (such as the remaining number of batteries and fault alarm) by the operator, facilitate scheduling and maintenance, and avoid local storage overflow by regularly uploading old data.

[0054] Referring to Figure 1 and Figure 3 , the specific installation and use steps of the intelligent battery replacement cabinet based on the RFID battery replacement mode are as follows:

[0055] First, the installation and initialization of the intelligent battery replacement cabinet. Fix the cabinet 1 in the battery replacement scene (such as an electric vehicle charging station), ensure that the center height of the card reading area is 1.2 meters, which meets the ergonomics; connect the power supply system, convert AC 220V power adapter to DC 12V / 5V, power supply for control unit, RFID card reading device 3, cabinet door driving mechanism, etc., and the standby battery (12V / 2Ah) supports 30 minutes operation after power failure; initialize the control unit, import user information database and battery information database through USB interface, complete signal calibration of RFID card reading device 3, and ensure stable reading within a radius of 0.5 meters.

[0056] Then the user replaces the battery. The specific process includes the following steps:

[0057] Step 1: Information reading of battery 4

[0058] The user removes the old battery 4 from the electric bicycle, and places the RFID card strip 5 on the side of the battery close to the card reading area on the front side of the cabinet 1. The RFID card reading device 3 emits a 13.56MHz radio frequency signal through the antenna, activates the card strip and reads the user ID and battery ID.

[0059] Step 2: Identity verification and battery 4 matching

[0060] The control unit receives the information transmitted by the card reading device, matches the user ID in the local user information database, and if the account is normal, further queries the battery 4 information database to filter out the available battery 4 with battery capacity ≥80% (such as battery No. B003 stored in No. 2 compartment).

[0061] Step 3: Cabinet door opening and prompting

[0062] The control unit sends an unlock instruction to the cabinet door driving mechanism of a certain battery storage compartment 2, the electromagnetic lock is powered off, and at the same time the indicator light 6 is green and the loudspeaker 7 plays "No. 2 cabinet door has been opened, please take out the new battery".

[0063] Step 4: Replacement of new and old batteries 4

[0064] After the user takes out the new battery 4, the old battery is placed in the designated old battery storage compartment 2, and then the cabinet door is closed; the inside limit switch of the cabinet door feeds the "closed" signal to the control unit, triggering the old battery information writing (such as updating the remaining battery capacity to 15%), and at the same time the control unit sends an instruction to the prompt module, the indicator light 6 is turned off, and the loudspeaker 7 plays a "operation completed" prompt sound.

[0065] Step 5: Data processing and storage

[0066] If there is a network connection, the communication module will upload the battery replacement record (time, user ID, new and old battery ID) to the server through the MQTT protocol; if there is no network, the record is temporarily stored in the local storage module, and will be automatically uploaded after the network is restored.

[0067] Finally, maintenance and abnormal processing, including regular maintenance, checking the lubrication state of the cabinet door driving mechanism through the back access of the cabinet 1, cleaning the surface dust of the RFID card reading antenna, and ensuring the signal strength of the card reading area; fault processing, if the indicator light 6 shows yellow flashing and is accompanied by the "cabinet door failure" voice prompt, the control unit records the fault code (such as E01: cabinet door not completely closed), the operation and maintenance personnel remotely locate and on-site troubleshoot through the server.

[0068] The implementation principle of the utility model is: through the non-contact information acquisition of RFID card strip 5 and RFID card reading device 3, local data processing of control unit, automation cabinet door control and the cooperation of multimodal prompt, the intelligent battery replacement mode of "without APP / two-dimensional code / NFC card, just rely on reading, offline use" is realized; break through the dependence of traditional scheme on terminal equipment and network, through hardware integration and logic design, the battery replacement process is simplified to "close to card reading, automatic cabinet opening, battery replacement 4" three steps, which significantly improves the convenience, reliability and full-scene applicability.

[0069] The embodiments of the specific embodiment are the preferred embodiments of the utility model, and do not limit the protection scope of the utility model, so: equivalent changes made according to the structure, shape and principle of the utility model should be covered in the protection scope of the utility model.
