Description

Technical Field

[0001] The present invention relates to the field of interaction technologies, and in particular, to an interaction method, a first device, a second device, a server, a third device, an interaction system, a vehicle, and a computer-readable storage medium. Background Art

[0002] In related technologies, electronic interaction devices based on sound waves rely on independent sound wave emission devices. Such electronic interaction devices are separated from the existing devices of application devices and require additional devices such as ultrasonic generators and speakers. This separated architecture results in low device integration. It not only requires additional deployment of multiple hardware modules in application devices but also brings greater system design complexity due to factors such as space, power supply, and environmental interference. At the same time, since these devices are often exposed on the surface of application devices, they are extremely vulnerable to the influence of harsh external environments such as dust, water vapor, and vibration, resulting in a decline in device performance or even damage, further affecting the stability and interaction reliability of the overall system. In addition, the reuse rate of these devices is low, and they are only used for sound wave communication, failing to effectively utilize the existing actuator resources of application devices, increasing costs and maintenance complexity. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. For this reason, one objective of the present invention is to propose an interaction method, which can achieve the function of directly using a motor for sound wave interaction, no longer relying on additional sound wave emission devices, reducing the need for additional hardware devices, lowering device costs, and at the same time avoiding the damage risk of additional hardware devices, thereby improving the reliability of interaction.

[0043] According to the interaction method of the embodiments of the present invention, the server can receive and process interaction information to obtain interaction feedback information. Among them, the interaction information is obtained according to a first sound wave signal emitted by a first motor of a first device. Specifically, after the first controller obtains an interaction request, the first controller controls the first motor to operate, causing itself to vibrate, and then emits a first sound wave signal with a specific frequency and specific loudness. This signal carries the interaction information, thereby enabling the acoustic transmission of information. Since this method directly reuses the existing first motor of the first device itself as the source of the sound wave signal, without the need to additionally configure a dedicated sound wave transmitter (such as a speaker or an ultrasonic module), it can effectively reduce the dependence on external hardware devices, reduce the overall hardware complexity and cost of the system.

Since this method directly reuses the first motor already existing in the first device itself as the source for emitting the acoustic wave signal, without the need to additionally configure a dedicated acoustic wave transmitter (such as a speaker or an ultrasonic module), it can effectively reduce the dependence on external hardware devices and lower the overall hardware complexity and cost of the system.

Detailed implementation manners

[0081] Embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention will be described in detail below.

[0082] With the rapid development of the Internet, electronic payment has become an important way of modern financial transactions. The key to this payment method lies in how to accurately verify personal identity. The basic methods of personal identity verification can be divided into three types: First, identity authentication based on private information. This authentication method relies on information mastered by the consumer himself, such as ID number, name, password, etc. Its advantage is easy to implement, but the disadvantage is that the information is easily stolen, posing a security risk.

[0083] Second, identity authentication based on items held by the user, such as bank cards, loan vouchers, credit cards, USB tokens, etc. The advantage of this method is relatively high reliability, but there is a risk of loss or theft of the items.

[0084] Third, identity authentication based on biometrics, which verifies identity by detecting unique biometric features of the user (such as palm prints, faces, irises, voiceprints, etc.). The advantage of this method is strong anti-counterfeiting performance, not easily stolen or copied, and high security.

[0085] Among them, the voiceprint feature is a voice spectrum realized through specific coding rules. Therefore, the voiceprint trait can carry identity information. Compared with traditional information such as passwords and ID numbers, voiceprint authentication has the advantages of quickness, stability, anti-counterfeiting performance, and easy portability.

[0086] Electronic payment includes mobile payment, which can refer to the operation of sending transaction instructions to banks or financial institutions via the Internet using intelligent devices such as mobile phones, smart watches, and AR glasses to complete fund transfer. The advantage of this method is to avoid the risk of counterfeit currency and the trouble of manual change. Currently, the mainstream mobile payment methods can be divided into near-field payment technologies according to the information transmission method, including: infrared payment, Bluetooth payment, sound wave payment, NFC payment, and QR code payment. Among them, infrared payment has high requirements for device thresholds and requires special infrared emission and receiving devices to conduct; Bluetooth payment can perform near-field data exchange through Bluetooth devices, but requires the device to support the Bluetooth protocol, and the transmission stability of Bluetooth payment is affected by device compatibility, presenting certain security risks; Sound wave payment relies on sound frequencies to encode and transmit payment information and can complete the transmission of payment instructions within a short distance. Sound wave payment does not rely on cellular network data, has low latency, does not require waiting during payment, does not require contact, and has a fast payment speed, being applicable to scenarios such as charging pile payment, parking payment, toll station payment, and vehicle maintenance; NFC payment uses an NFC chip to achieve short-distance payment interaction. This payment method is limited by the compatibility of payment terminal devices, and the transaction distance is usually short (generally within 10 cm); QR code payment completes payment by scanning QR codes, such as mainstream payment methods like WeChat Pay and Alipay. This payment method relies on the mobile phone camera, and in the case of damaged or soiled QR codes, the payment may fail.

[0087] Figure 1 It is a functional block diagram of an existing QR code sound wave payment device and its payment system, as Figure 1 shown. This payment system realizes the processing of transaction applications between embedded devices such as mobile phones, watches, and glasses by scanning QR codes. When a transaction occurs, the user opens the payment QR code on the terminal device, and the QR code sound wave payment device encodes the QR code information into a specific sound wave signal and emits the sound wave signal through the speaker. The payment system settlement platform receives the sound wave signal through the microphone and parses the QR code information therein, then verifies the transaction information and completes the payment deduction process. After the payment is completed, the QR code sound wave payment device returns the transaction result to the user terminal and uploads the transaction data to the settlement platform of the payment system to complete the entire transaction process.

[0088] As Figure 1 shown, the QR code sound wave payment device includes a power supply module, a microphone, a speaker, a power amplifier module, a processor module, a QR code module, and a human body monitoring module.

[0089] However, the two-dimensional code sound wave payment device in the prior art has obvious deficiencies when applied to the electric vehicle scenario. This payment device is relatively independent of the electric vehicle system, with low integration. It requires additional deployment of multiple hardware modules, significantly increasing the equipment complexity and cost of the whole vehicle. At the same time, due to the external device being easily exposed to environmental factors such as dust, water vapor, and vibration, there is also a risk of being damaged easily, resulting in an increase in maintenance costs. Moreover, this method relies on a dedicated App (Application) and the two-dimensional code generation mechanism, cannot complete the payment process independently of the two-dimensional code, and requires an Internet connection to be maintained. It is difficult to complete payment transactions in areas with poor signal or no cellular network coverage. Also, this method requires an additional mobile device (such as a mobile phone or a POS (Point of Sale terminal) machine) to participate in the transaction process and cannot achieve autonomous execution of the entire transaction process. In addition, the authentication method for transaction targets in this delivery method is too single, presenting a security hazard.

[0090] Generally speaking, in the related art, the electronic interaction device based on sound waves relies on an independent sound wave emitting device. Such an electronic interaction device is separated from the existing devices of the electric vehicle and requires additional devices such as an ultrasonic generator and a speaker. This separated architecture results in low device integration. It not only requires additional deployment of multiple hardware modules on the vehicle body but also brings greater system design complexity due to factors such as space, power supply, and environmental interference. At the same time, since these devices are often exposed on the vehicle surface, they are extremely vulnerable to the influence of harsh external environments such as dust, water vapor, and vibration, resulting in a decline in device performance or even damage, further affecting the stability and interaction reliability of the overall system. In addition, the reuse degree of these devices is relatively low. They are only used for sound wave communication and do not effectively utilize the existing actuator resources of the electric vehicle, increasing the cost and maintenance complexity of the whole vehicle.

[0091] In view of the above problems, an embodiment of the present invention proposes an interaction method. This interaction method can be used for a first device, where the first device can be a device having a first controller and a first motor, such as a vehicle. This interaction method can realize the function of directly using the motor for sound wave interaction, no longer relying on an additional sound wave emitting device, reducing the need for additional hardware devices, lowering the device cost, and at the same time avoiding the risk of damage to the additional hardware devices, thereby improving the reliability of the interaction.

[0092] The following refers to Figures 2 - 9 Describe the interaction method according to the embodiment of the present invention.

[0093] Figure 2 is a flowchart of the interaction method according to an embodiment of the present invention. As Figure 2 shown, the interaction method of the embodiment of the present invention includes at least steps S1 - S2.

[0094] S1. The first controller obtains an interaction request.

[0095] In some embodiments, the interaction request can be triggered either by the internal logic of the first device locally or by a signal sent by an external system. Specifically, the interaction request can be initiated by the first device itself. For example, when the vehicle detects that the charging gun is inserted and successfully locked by the charging pile, the local sensor of the first device detects the state change, and then transmits the interaction request to the first controller through the in-vehicle bus or other internal communication buses. It can also be initiated by an external device or system. For example, during the transaction initiation phase, a third-party payment platform sends the interaction request to the first device by calling an API interface, and the interaction request is transmitted to the first controller through a wireless communication module (such as Wi-Fi, cellular communication, Bluetooth, etc.) for processing. In addition, the interaction request can also originate from user operations. For example, after the user clicks the payment button or confirms the interaction instruction in the in-vehicle system, the in-vehicle system generates an interaction request and transmits it to the first controller. After receiving the interaction request, the first controller immediately enters the subsequent acoustic signal sending process.

[0096] S2. The first controller controls the first motor to emit a first acoustic signal, and the first acoustic signal contains interaction information, which is obtained based on the interaction request.

[0097] In some embodiments, the first controller can be a motor controller. By controlling the first motor to rotate at a high speed or vibrate in a specific manner, the first motor itself emits a first acoustic signal with a specified frequency and specified loudness, and the interaction information is carried in this acoustic signal, thus realizing the function of transmitting information through sound waves.

[0098] In some embodiments, after obtaining the interaction request, the first device can obtain the interaction information required for the transaction activity, including but not limited to: necessary data related to the transaction process such as payment amount, product number, serial number, buyer token, timestamp, etc.

[0099] In some embodiments, the interaction method of the embodiments of the present invention uses the power system that electric vehicles are necessarily equipped with, and realizes emitting acoustic waves with a specified frequency / amplitude by reusing the motor. Since no additional hardware is required, it can be widely deployed through OTA (Over-The-Air, wireless). That is, software updates or function upgrades are remotely pushed through a wireless network without manually replacing the hardware on the vehicle, and the implementation method is easy.

[0100] In some embodiments, the interaction method of the embodiments of the present invention does not rely on two-dimensional codes and does not rely on the assistance of additional mobile devices. It can be independent of third-party devices and can perform short-distance communication without relying on cellular networks, Bluetooth, Wi-Fi, etc. It can be applied to electric vehicle charging stations to achieve charging protocol matching, charging request sending, unattended charging, automatic settlement, and can also be used for automatic payment in parking lots.

[0101] In some embodiments, since the loudness and frequency of the acoustic wave signal generated by the motor are adjustable, it has the effect of secure transmission in the physical sense, and the transmitted content is not easily eavesdropped or stolen.

[0102] According to the interaction method of the embodiments of the present invention, after the first controller obtains an interaction request, the first controller controls the first motor to operate, causing itself to vibrate, and then emitting a first acoustic wave signal with a specific frequency and specific loudness. This signal carries the interaction information, thereby enabling the acoustic wave transmission of information. Since this method directly reuses the existing first motor of the first device itself as the source for emitting the acoustic wave signal without the need to additionally configure a dedicated acoustic wave transmitter (such as a speaker or ultrasonic module), it can effectively reduce the dependence on external hardware devices, reduce the overall hardware complexity and cost of the system. In addition, since the first motor itself is the original standard configuration of the first device, its stability and reliability have been fully verified. Its position is relatively fixed, its environmental adaptability is strong, and it is not easily damaged by external environmental influences, avoiding the risk of damage to the independent acoustic wave emission device in the external environment in the prior art, thereby improving the reliability of the interaction.

[0103] In some embodiments, the first controller controls the operation of the first motor by sending a control signal to the first motor, and the control signal includes transaction information. Among them, the transaction information includes, but is not limited to: necessary data related to the transaction process such as payment amount, product number, serial number, buyer token, timestamp, etc.

[0104] In some embodiments, the control signal is a signal encoded according to a preset encoding rule.

[0105] Among them, the preset encoding rules may include, but are not limited to: Frequency Shift Keying (FSK), Amplitude Shift Keying (ASK), Phase Shift Keying (PSK), etc. In addition, the encoding style of the encoder may adopt character sets such as American Standard Code for Information Interchange (ASCII) or Chinese Internal Code Extension (GBK). The encoder can assemble the interaction information to be transmitted into a preset format message that meets the requirements of the communication protocol. The message may include: a 1-byte flag bit, a 2-byte length bit, a 1-byte parity check bit, and several bytes of data bits to ensure the integrity and accuracy of the information parsing process.

[0106] Specifically, the first controller can encode according to the interaction information using the above preset encoding rules to obtain a sound wave signal in which the sound wave characteristics correspond to and match the interaction information. Then, the first controller further generates an inverter control signal based on the generated sound wave signal. Among them, the inverter control signal can be a PWM (Pulse Width Modulation) signal, which is used to control the first motor to emit a corresponding sound wave signal. The first controller sends the PWM signal to the inverter, and the inverter controls the current amplitude and frequency in the stator coil of the first motor according to the duty cycle of the PWM signal, so that the first motor generates mechanical vibrations with a specific frequency and loudness. Thus, the first motor can emit a first sound wave signal containing the interaction information, achieving the purpose of transmitting the interaction information through sound waves.

[0107] In some embodiments, before the first controller controls the first motor to emit the first sound wave signal, the interaction method further includes: the first controller obtains a confirmation instruction from the user for the interaction information.

[0108] In some embodiments, after receiving the interaction request, the first device does not immediately perform the sound wave emission action, but requires the user to first perform an active confirmation operation, thereby enhancing the control authority and transaction security during the interaction process.

[0109] Specifically, the first controller can display interaction information (such as payment method, payment amount, product name, transaction serial number, payment channel, payment status, etc.) to the user. After the user confirms that the above interaction information is correct, a confirmation instruction is generated and sent. After receiving the user's confirmation instruction, the first controller can merge and encode the interaction information and the confirmation instruction, modulate the merged data according to a preset encoding rule, and generate a corresponding sound wave signal. Subsequently, the first controller generates a PWM signal based on the sound wave signal, controls the inverter to work, and drives the first motor to operate, so that the first motor emits a first sound wave signal containing the interaction information and the confirmation instruction, realizing the secure transmission of information.

[0110] In some embodiments, the generation methods of the user confirmation instruction may include, but are not limited to: physical button confirmation, touch screen click confirmation, voice control instruction confirmation, biometric confirmation (such as fingerprint recognition, face recognition), etc. Different confirmation methods can be flexibly selected according to specific application scenarios to meet the requirements of different security levels and interaction convenience.

[0111] In some embodiments, the interaction method further includes: the first controller presents the confirmation information containing the interaction information to the user through the terminal device for the user to confirm.

[0112] Among them, the terminal device may include, but is not limited to, an in-vehicle central control screen, an intelligent instrument panel, a head-up display device (HUD, Heads Up Display), etc. When the user checks that the displayed transaction details are correct, the user can click the "Confirm" button on the interface of the terminal device. In response to the confirmation instruction issued by the user, the first controller merges and encodes the user confirmation instruction and the target interaction information, and modulates them into a first sound wave signal. If the user clicks the "Cancel" button on the terminal device interface, the generation of the first sound wave signal is stopped, and a "Transaction Cancelled" or similar prompt message is popped up on the terminal device to prompt the user that the current operation has been aborted, ensuring the security and controllability of the transaction process.

[0113] In some embodiments, the terminal device is the terminal device of the first device or a mobile terminal connected to the first controller. Among them, the terminal device of the first device may refer to the display and interaction device integrated in the first device (such as a vehicle), for example: an in-vehicle central control screen, an intelligent instrument panel, a head-up display device (HUD), etc. In this case, the first controller inside the first device can directly call the built-in terminal interface of this device to display the interaction information to the user for confirmation.

[0114] In some embodiments, the mobile terminal connected to the first controller may refer to an external device connected to the first controller by wireless or wired means, such as: mobile phones, tablets, smart watches, in-vehicle passenger entertainment tablets externally connected to vehicles, etc. In this case, the first controller may send the interaction information to the mobile terminal by means such as Bluetooth, Wi-Fi, NFC (Near Field Communication), wired interfaces (such as USB, Universal Serial Bus), etc., and the mobile terminal displays it to the user and receives the confirmation instruction from the user.

[0115] In some embodiments, the interaction request may be that the first device actively detects an acoustic wave interaction request or receives an acoustic wave interaction request through an application programming interface.

[0116] Among them, the first device actively detecting an acoustic wave interaction request may mean that the first device actively listens for triggering conditions such as external physical states, network connection conditions, user operation behaviors, etc. periodically or continuously through its built-in control logic to determine whether there is a scenario that requires performing an acoustic wave interaction. For example, when it detects that a charging gun is inserted into a vehicle, the first device can automatically generate an acoustic wave interaction request related to the charging fee. And receiving an acoustic wave interaction request through an application programming interface may mean that the first device receives a target interaction request sent by a third-party application in a way of API (Application Programming Interface) call, and the first device executes the subsequent acoustic wave interaction process after receiving the request.

[0117] In some embodiments, the interaction information includes transaction information. Specifically, when the interaction information includes transaction information, the first device transmits this transaction information to the second device through the first acoustic wave signal. This provides basic data for subsequent payment verification, authentication, settlement, etc. Since transaction information usually contains sensitive data (such as accounts, amounts, etc.), encryption or other means may be required to ensure the security of the information during transmission. An authentication mechanism can be combined to ensure the security and legality of the information transmission process.

[0118] In some embodiments, the transaction information includes at least one of the following: payment method, payment amount, commodity name, transaction serial number, payment channel, payment status. In acoustic wave interaction, the transmission of transaction information helps to automate transactions, ensure that all transaction details can be accurately transmitted to the receiving device, and can be verified and processed during transaction settlement.

[0119] In some embodiments, the first device further includes a first acoustic wave receiving module, and the interaction method further includes: the first acoustic wave receiving module receives a second acoustic wave signal containing first feedback information, and the first feedback information includes a transaction result.

[0120] Among them, receiving the second acoustic wave signal containing the first feedback information can be implemented by a first acoustic wave receiving device in the first device, such as a built-in microphone, an external microphone, or an acoustic wave sensing device with a specific frequency, etc. This acoustic wave receiving device can collect the second acoustic wave signal containing the first feedback information and convert the collected analog acoustic wave signal into a digital signal for subsequent processing.

[0121] In some embodiments, a decoding module built into the first device can demodulate and restore the received second acoustic wave signal based on a preset modulation and demodulation protocol, so as to extract the valid first feedback information therein.

[0122] In some embodiments, the transaction result is used to indicate whether the corresponding service interaction is successfully completed, such as indicating whether the payment is completed, whether the order is generated, or whether the recharge is successful, etc.

[0123] In some embodiments, the first device can present the transaction result information to the user in a graphical manner through its terminal device (such as an in-vehicle central control screen, an instrument panel, or a head-up display device, etc.) to improve the interaction transparency and user experience. For example, a text prompt such as "Payment successful" or "Payment failed" can be popped up on the display screen, or real-time feedback can be provided in the form of voice broadcast, etc.

[0124] In some embodiments, the interaction method further includes: the first controller controls the first motor to emit a third acoustic wave signal, and the third acoustic wave signal contains the device information of the first device. Among them, the device information of the first device may include, but is not limited to: device ID (Identity), device model, manufacturer information, device configuration, etc.

[0125] In some embodiments, if the first device is a vehicle, the device information may include, but is not limited to: vehicle identification number, motor number, license plate information, vehicle model information, manufacturer information, etc.

[0126] In some embodiments, the device information carried by the third acoustic wave signal can provide an important data basis for subsequent authentication and verification. For example, it may be necessary to verify the legitimacy of the first device or authorize the first device. The included device information can be used as part of the identity verification to confirm the legitimacy of the first device by comparing it with the information in the device database. This process can enhance the security of the system and ensure that only authorized devices can continue with subsequent operations.

[0127] In some embodiments, the first device further includes a first acoustic wave receiving module, and the interaction method further includes: the first acoustic wave receiving module receives a fourth acoustic wave signal containing second feedback information, and the second feedback information includes an authentication result, and the authentication result is obtained by authenticating the authentication information generated according to the device information.

[0128] Among them, the second feedback information includes an authentication result. The authentication result may refer to a result of device legality or identity verification. This result can be a "success" or "failure" flag, indicating whether the device has passed the security verification. For example, if the device information matches the records in the database, "authentication success" is returned; otherwise, "authentication failure" is returned.

[0129] In some embodiments, the fourth acoustic wave signal carries the authentication result and is received by the first acoustic wave receiving module of the first device. The role of the fourth acoustic wave signal is to return the authentication result from the second device to the first device to notify the result of the authentication process. For example, in a vehicle scenario, after verification, if device information such as the vehicle identification number successfully matches, the fourth acoustic wave signal will return the information of "authentication success", indicating that the device can continue to perform operations.

[0130] In some embodiments, the authentication result can be presented to the user in a graphical manner through the terminal device of the first device (such as an in-vehicle central control screen, instrument panel, HUD, etc.), thereby improving the interaction transparency and user experience. For example, text prompts such as "authentication success" and "authentication failure, please try again" can be displayed on the screen, or feedback can be provided through voice announcements and other means.

[0131] In some embodiments, the first device can be a vehicle. The vehicle can be the active or passive party of acoustic wave interaction and can interact with external devices including charging piles, parking gates, gas station terminals, access control systems, unattended stores, etc.

[0132] An embodiment of the second aspect of the present invention also proposes an interaction method, which is used for a second device. The second device includes a second controller and a second acoustic wave receiving module, and among them, the second acoustic wave receiving module can be a device such as a microphone that can sense acoustic wave signals.

[0133] Figure 3 It is a flowchart of the interaction method according to another embodiment of the present invention. As Figure 3 shown, the interaction method of the embodiment of the present invention at least includes steps S10 - S11.

[0134] S10, the second acoustic wave receiving module receives a first acoustic wave signal, the first acoustic wave signal is emitted by the first motor of the first device, and the first acoustic wave signal contains interaction information.

[0135] Specifically, after the acoustic wave interaction is initiated, the second acoustic wave receiving module in the second device continuously monitors the acoustic wave signals within a predetermined frequency band (such as 1 kHz - 8 kHz) until it successfully receives the first acoustic wave signal containing interaction information. Then, the received analog acoustic wave signal is band-pass filtered to remove environmental noise and signals outside the target frequency band. Then, the analog signal is subjected to analog-to-digital conversion at a set sampling rate (such as 16 kHz or 32 kHz) to obtain a digitalized acoustic wave signal sequence.

[0136] S11. The second controller obtains the interaction information based on the first acoustic wave signal.

[0137] Specifically, the second controller can extract the interaction information in the first acoustic wave signal through decoding techniques and perform corresponding operations based on this information.

[0138] According to the interaction method of the embodiment of the present invention, the second device can receive the first acoustic wave signal generated by the operation of the first motor of the first device through its own configured second acoustic wave receiving module, and this signal contains interaction information. Specifically, after the first controller obtains an interaction request, the first controller controls the operation of the first motor to make itself start vibrating, and then emits the first acoustic wave signal with a specific frequency and specific loudness, and this signal carries the interaction information, thereby enabling the acoustic wave transmission of information. Since this method directly reuses the existing first motor of the first device itself as the source for emitting acoustic wave signals without the need to additionally configure a dedicated acoustic wave transmitter (such as a speaker or an ultrasonic module), it can effectively reduce the dependence on external hardware devices, reduce the overall hardware complexity and cost of the system. In addition, since the first motor itself is the original standard configuration of the first device, its stability and reliability have been fully verified, its position is relatively fixed, its environmental adaptability is strong, and it is not easily damaged due to external environmental influences, avoiding the risk of damage to the independent acoustic wave emission device in the prior art under the external environment, thereby improving the reliability of the interaction.

[0139] In some embodiments, the interaction information is obtained by the second controller decoding the first acoustic wave signal according to a preset decoding rule.

[0140] Specifically, after receiving the digital acoustic wave signal, the second controller in the second device can decode it according to the preset decoding rule. The preset decoding rule can adopt standard character encoding methods, such as the American Standard Code for Information Interchange (ASCII), GBK (Chinese Character Encoding Extension Specification), or Unicode (Universal Code), etc.

[0141] Further, during the decoding process, the second controller first performs an integrity check on the acoustic wave signal packet. Common check methods include CRC check, parity check, or hash check. After passing the check, the second controller will parse the message structure according to the frame format, identifying the flag bits, length fields, data fields, and check fields in the message. Then, the second device converts the data field according to the specified character encoding method to restore the original interaction information.

[0142] In some embodiments, the second device further includes an acoustic wave transmitting module, and the interaction method further includes: the second controller controls the acoustic wave transmitting module to transmit a fifth acoustic wave signal, and the fifth acoustic wave signal contains the determination information corresponding to the interaction information.

[0143] In some embodiments, the acoustic wave transmitting module can be devices such as ultrasonic sensors, buzzers, speakers, etc.

[0144] In some embodiments, the fifth acoustic wave signal contains "confirmation information" related to the interaction information, which is a confirmation or response to the interaction information. This information can be used to ensure effective information exchange between the first device and the second device, or to confirm certain parameters of the interaction process.

[0145] Specifically, after the second device completes the reception and parsing of the interaction information, to ensure that the transaction behavior is initiated by the authorization of a legitimate user and to avoid misoperation or unauthorized automatic transactions, it will generate a determination information corresponding to the interaction information, encode the determination information and the interaction information to generate a corresponding fifth acoustic wave signal, and send it to the first device. After receiving the fifth acoustic wave signal, the first device presents the determination information containing the corresponding interaction information to the user for confirmation through the terminal device. When the user checks that the transaction details are correct, they can click the "confirm" button on the interface of the interaction device. The first device will then merge and encode the user confirmation instruction and the interaction information, and modulate them into a first acoustic wave signal for transmission. The second device will obtain the first acoustic wave signal containing the confirmation instruction as the final authorization signal for executing the transaction or continuing the subsequent process. This method forms a two-way confirmation interaction mechanism based on acoustic waves, which can effectively reduce the probability of incorrect transactions and improve the controllability of the interaction and user trust.

[0146] In some embodiments, the second device further includes a first communication module, and the interaction method further includes: the second controller controls the first communication module to send the interaction information.

[0147] Specifically, when the second device receives the first acoustic wave signal containing the user confirmation instruction sent by the first device, the second controller in the second device can decode the first acoustic wave signal based on a preset decoding rule to obtain the interaction information. Then, the second controller controls the first communication module to upload the interaction information to the server.

[0148] In some embodiments, the first communication module may be a Wi-Fi module, a cellular communication module (such as a 4G or 5G module), or a Bluetooth module, etc., which is suitable for data transmission requirements in different application environments.

[0149] In some embodiments, the interaction information includes transaction information. Specifically, the second acoustic wave receiving module in the second device may receive the first acoustic wave signal sent from the first device, and the second controller may decode the first acoustic wave signal based on a preset decoding rule to obtain the interaction information. The second controller may further extract the transaction information related to the transaction from the interaction information.

[0150] In some embodiments, the transaction information includes at least one of the following: payment method, payment amount, commodity name, transaction serial number, payment channel, payment status.

[0151] In some embodiments, the second device further includes an acoustic wave transmitting module, and the interaction method further includes: the first communication module receives the transaction result corresponding to the transaction information. The second controller controls the acoustic wave transmitting module to transmit a second acoustic wave signal including the first feedback information, and the first feedback information includes the transaction result.

[0152] Specifically, after the transaction settlement is completed, the transaction settlement platform will generate a corresponding transaction result according to the sent transaction information and send the transaction result back to the second device. The first communication module in the second device is responsible for receiving the transaction result and providing it to the second controller. The second controller encodes the transaction result into the first feedback information according to a preset encoding rule and sends the first feedback information in the form of an acoustic wave signal (i.e., the second acoustic wave signal) to the first device by controlling the acoustic wave transmitting module. The first acoustic wave receiving module in the first device receives the second acoustic wave signal including the first feedback information and converts the collected analog acoustic wave signal into a digital signal for subsequent processing by the first controller. The first controller decodes the digital signal based on a preset decoding rule, analyzes the included first feedback information, and thus extracts the transaction result to confirm the completion status of the transaction.

[0153] In some embodiments, the interaction method further includes: the second controller controls the first communication module to send the authentication information of the first device, and the authentication information is generated according to the device information of the first device. Among them, the generation method of the authentication information may include: directly using the device information as the authentication information; generating the authentication information after encrypting the device information (such as through symmetric encryption, asymmetric encryption, hash encryption, etc.); or generating a one-time authentication token according to the device information combined with dynamic elements such as the current timestamp and random number.

[0154] In some embodiments, the interaction method further includes: a second sound wave receiving module receives a third sound wave signal, which is emitted by a first motor of a first device, and the third sound wave signal includes device information of the first device.

[0155] Specifically, when the first device interacts with the second device, to ensure the security of the interaction and the legality of the device identity, the first controller may generate authentication information based on the device information of the first device. Then, according to a preset coding rule, the first controller encodes the authentication information to generate a control signal. The first controller controls the first motor to operate by sending the control signal to the first motor, so as to generate a third sound wave signal including the device information of the first device. Further, after the second device receives the third sound wave signal sent by the first device and including the authentication information of the first device, the second controller in the second device may decode the third sound wave signal based on a preset decoding rule to extract the authentication information of the first device. The second controller uploads the authentication information (such as vehicle identification number, motor number, license plate information, vehicle model information, etc.) to the server through the first communication module. The server verifies the legality of the first device according to the authentication information and performs subsequent interaction or transaction operations.

[0156] In some embodiments, the interaction method further includes: the second controller receives the authentication information of the first device, and the authentication information is generated according to the device information of the first device, and the device information of the first device is obtained according to the image information of the first device.

[0157] Among them, the image information of the first device can be obtained through an image acquisition device (such as a camera, a sensor, etc.). The image information may include the appearance of the first device, identifiers (such as license plates, barcodes, two-dimensional codes, etc.) or other feature images related to the first device. The image information can be used to extract the unique identification information of the device (such as device model, serial number, production date, etc.) through an image recognition algorithm (such as machine vision, deep learning, etc.).

[0158] In some embodiments, the second device further includes a sound wave emitting module, and the interaction method further includes: the second controller receives an authentication result, which is obtained by authenticating the first device according to the authentication information. The second controller controls the sound wave emitting module to emit a fourth sound wave signal including second feedback information, and the second feedback information includes the authentication result.

[0159] Specifically, the second controller controls the first communication module to send the authentication information of the first device to the server. The server will authenticate the first device according to the received authentication information, including verifying data integrity, validating transaction legality, identifying the identity of the transaction user, etc., so as to prevent information forgery or tampering. After the server completes the authentication process, the second controller receives the authentication result sent by the server. The authentication result may include information such as "authentication successful" or "authentication failed". The second controller can encode the authentication result to generate the second feedback information. This second feedback information not only contains the authentication result, but may also include more detailed information, such as device status, steps that can be continued after successful authentication, or prompts for re-authentication, etc.

[0160] Further, the second controller controls the acoustic wave emission module to emit a fourth acoustic wave signal containing the second feedback information to the first device. The first acoustic wave receiving module in the first device can receive the fourth acoustic wave signal and convert the signal into a digital signal for subsequent processing. Then, the first controller decodes the fourth acoustic wave signal according to a preset decoding rule and extracts the second feedback information from it. Based on the decoded feedback information, the first device will be able to know the authentication result and perform corresponding subsequent operations according to different feedback results. For example, continue the interaction, re-authenticate, or terminate the interaction, etc.

[0161] An embodiment of the third aspect of the present invention also proposes an interaction method, which is used for the server.

[0162] Figure 4 It is a flowchart of the interaction method according to another embodiment of the present invention. As Figure 4 shown, the interaction method of the embodiment of the present invention at least includes steps S20 - S22.

[0163] S20, receive interaction information, where the interaction information is obtained according to the first acoustic wave signal emitted by the first motor of the first device.

[0164] Specifically, the first controller controls the first motor to rotate at a high speed or vibrate in a specific manner, so that the first motor itself emits a first acoustic wave signal with a specified frequency and specified loudness. The interaction information is carried in this acoustic wave signal, thus realizing the function of transmitting information through acoustic waves.

[0165] Further, the second acoustic wave receiving module in the second device continuously monitors acoustic wave signals within a predetermined frequency band (such as 1 kHz - 8 kHz) until it successfully receives the first acoustic wave signal containing interaction information. Then, the received analog acoustic wave signal is band-pass filtered to remove environmental noise and signals outside the target frequency band. Then, the analog signal is analog-to-digital converted at a set sampling rate (such as 16 kHz or 32 kHz) to obtain a digitalized acoustic wave signal sequence. The second controller can extract the interaction information in the first acoustic wave signal through decoding techniques and perform corresponding operations based on this information.

[0166] Further, the second device can send the interaction information to the server through the first communication module, and the server can receive the interaction information through wireless communication.

[0167] S21, obtain interaction feedback information, where the interaction feedback information is obtained through interaction processing based on the interaction information.

[0168] In some embodiments, the interaction feedback information can be digital information or encoded data with a specific format or protocol, ensuring that it can be understood by the receiving party (such as the second device).

[0169] S22, send the interaction feedback information.

[0170] Specifically, after processing the interaction information, the server can send the generated interaction feedback information to the target device (such as the second device, etc.) through the network or communication interface.

[0171] According to the interaction method of the embodiments of the present invention, the server can receive and process the interaction information to obtain interaction feedback information. Among them, the interaction information is obtained based on the first acoustic wave signal emitted by the first motor of the first device. Specifically, after the first controller obtains the interaction request, the first controller controls the first motor to run, causing it to vibrate itself, and then emits the first acoustic wave signal with a specific frequency and specific loudness. This signal carries the interaction information, thereby enabling the acoustic wave transmission of information. Since this method directly reuses the existing first motor of the first device itself as the source for emitting acoustic wave signals without the need to additionally configure a dedicated acoustic wave transmitter (such as a speaker or ultrasonic module), it can effectively reduce the dependence on external hardware devices, reduce the overall hardware complexity and cost of the system. In addition, since the first motor itself is the original standard configuration of the first device, its stability and reliability have been fully verified. Its position is relatively fixed, its environmental adaptability is strong, and it is not easily damaged by external environmental influences, avoiding the risk of damage to the independent acoustic wave emission device in the prior art under the external environment, thereby improving the reliability of the interaction.

[0172] In some embodiments, the interaction information includes transaction information. Specifically, the server can receive the transaction information sent by the second device and call the transaction settlement platform according to the transaction information. The transaction settlement platform can complete settlement operations such as transaction deductions based on the transaction information and generate transaction results (such as successful transactions, payment failures, etc.). After the transaction settlement platform completes the settlement operation, it can feedback the transaction result to the server.

[0173] In some embodiments, the transaction information includes at least one of the following: payment method, payment amount, commodity name, transaction serial number, payment channel, payment status.

[0174] In some embodiments, when the vehicle is purchased or first connected to the platform, it has been pre - bound with a bank account or a third - party payment account. Once the binding is successful, the unique identifier of the vehicle (such as the vehicle identification number or motor number) can be automatically associated with the payment account. During subsequent transactions, the system can quickly identify the user's identity based on the unique identifier and achieve automatic deduction without the user having to repeatedly enter the account number or authorize each time a transaction occurs.

[0175] Therefore, since the motor or vehicle code itself is unique, it can be used as a natural identity authentication basis in certain scenarios, significantly simplifying the traditional registration and authentication processes. Compared with the traditional method that requires steps such as registering an account first, binding a bank card, or manual authorization, the present invention can complete device identification, identity verification, and payment settlement through the acoustic wave interaction technology, greatly improving the convenience of interaction and the user experience. This acoustic wave interaction technology can also be extended for near - field transmission of any encoded information.

[0176] In some embodiments, the interaction feedback information includes the transaction result corresponding to the transaction information. For example: successful transaction, transaction failure, etc. Specifically, the server can send the transaction result to the second device. The first communication module in the second device is responsible for receiving the transaction result and providing it to the second controller. The second controller encodes the transaction result into the first feedback information according to the preset encoding rule and sends the first feedback information in the form of an acoustic wave signal (i.e., the second acoustic wave signal) to the first device by controlling the acoustic wave emission module. The first acoustic wave receiving module in the first device receives the second acoustic wave signal containing the first feedback information and converts the collected analog acoustic wave signal into a digital signal for subsequent processing by the first controller. The first controller decodes the digital signal based on the preset decoding rule, analyzes the contained first feedback information, and thus extracts the transaction result to confirm the completion status of the transaction.

[0177] In some embodiments, before obtaining the interaction feedback information, the interaction method further includes: receiving the authentication information of the first device; obtaining an authentication result, which is obtained by authenticating the first device according to the authentication information; and sending the authentication result. Specifically, the server can receive the authentication information of the first device sent by the first communication module in the second device, and the server can authenticate the first device according to the received authentication information, including verifying data integrity, validating transaction legality, identifying the identity of the transaction user, etc., so as to prevent information forgery or tampering. When the server completes the authentication process, the server can send the authentication result to the first communication module in the second device. After receiving the authentication result, the first communication module transmits the authentication result to the second controller. The second controller then encodes the authentication result and generates second feedback information containing the result. The second controller controls the acoustic wave emission module to emit a fourth acoustic wave signal containing the second feedback information, and this signal is transmitted to the first device, thereby feeding back the authentication result to the first device.

[0178] In this way, the first device can receive the authentication result, such as "authentication successful" or "authentication failed", through the acoustic wave signal and perform corresponding operations according to the authentication result. In this way, the security and identity verification in the interaction process are effectively guaranteed, and the participation of illegal devices or users is avoided.

[0179] In some embodiments, the interaction feedback information is obtained by performing interaction processing according to the interaction information after the authentication of the first device is passed. This means that only when the authentication information is effectively verified and the identity of the first device is confirmed can the subsequent interaction process continue. If the authentication fails, the interaction will be interrupted or a re-authentication will be requested to ensure the security and legality of the transaction.

[0180] An embodiment of the fourth aspect of the present invention also proposes an interaction method, which is used for a third device.

[0181] Figure 5 is a flowchart of an interaction method according to another embodiment of the present invention. As Figure 5 shown, the interaction method of the embodiment of the present invention at least includes steps S30-S32.

[0182] S30, obtaining the device information of the first device according to the image information of the first device, where the first device is a device for sending a first acoustic wave signal of interaction information.

[0183] In some embodiments, the third device can collect the image information of the first device through an image acquisition module and analyze the image using an image recognition algorithm to extract the recognizable features of the first device to further obtain the device information of the device. The device information of the first device may include but is not limited to: device ID, device model, manufacturer information, device configuration, etc.

[0184] S31. Obtain authentication information, which is generated based on device information.

[0185] Specifically, if the first device is a vehicle, the device information may include, but is not limited to: vehicle identification number, motor number, license plate information, vehicle model information, manufacturer information, etc. The third device can further retrieve or match the corresponding vehicle registration information through the identified vehicle information, such as the owner's payment information, bound payment channels, etc. Based on the above vehicle information, an identity identification code uniquely corresponding to the first device can be generated, and the vehicle information, payment information, bound payment channels, and identity identification code are combined to generate the authentication information of the first device.

[0186] S32. Send the authentication information.

[0187] Specifically, the third device can send the authentication information to the second device by means of acoustic wave signals or by means of wireless communication for subsequent authentication in the server.

[0188] According to the interaction method of the embodiments of the present invention, the third device can extract device information containing the first device identifier or attribute by collecting and identifying the image information of the first device, and then generate and send the authentication information to the second device. This authentication method can effectively prevent interception, replay, or tampering attacks and improve transaction security. Moreover, the acoustic wave signal containing the interaction information is generated by the first motor in the first device. That is, after the first controller obtains the interaction request, the first controller controls the first motor to run, causing it to vibrate itself, and then emits a first acoustic wave signal with a specific frequency and specific loudness. This signal carries the interaction information, thereby enabling the acoustic wave transmission of information. Since this method directly reuses the existing first motor of the first device itself as the source of the acoustic wave signal without the need to additionally configure a dedicated acoustic wave transmitter (such as a speaker or an ultrasonic module), it can effectively reduce the dependence on external hardware devices, reduce the overall hardware complexity and cost of the system. In addition, since the first motor itself is the original standard configuration of the first device, its stability and reliability have been fully verified. Its position is relatively fixed, its environmental adaptability is strong, and it is not easily damaged by the external environment, avoiding the risk of damage to the independent acoustic wave emission device in the external environment in the prior art, thereby improving the reliability of the interaction.

[0189] In some embodiments, the present invention performs secondary composite authentication on the transaction information in combination with the authentication information, improving transaction security and avoiding signal interception and replay attacks during the generation of acoustic wave signals.

[0190] In some embodiments, the interaction method further includes: generating acoustic wave transceiver direction adjustment information according to the relative positions of the first device and the second device, and sending the acoustic wave transceiver direction adjustment information to the second device, where the second device is a device that interacts with the first device through acoustic waves.

[0191] Among them, the relative positions of the first device and the second device may refer to the spatial relationship between the two devices, such as distance, angle, etc. These information determine the transmission path and intensity of the acoustic wave signal. The transmission efficiency and reliability of the acoustic wave signal are affected by the device positions. For example, the signal may be attenuated or distorted due to physical obstacles (such as walls, metal objects, etc.) or too far distance. Therefore, the third device can monitor the positions of the first device and the second device in real time and generate the acoustic wave transceiver direction adjustment information based on this, which can optimize the signal transmission effect.

[0192] In some embodiments, the acoustic wave transceiver direction adjustment information may include: the emission angle of the acoustic wave, the reception angle of the acoustic wave, and signal intensity adjustment, etc. The third device can send the acoustic wave transceiver direction adjustment information to the second device in the form of wireless communication (such as Wi-Fi, Bluetooth, etc.) or acoustic waves. After receiving the acoustic wave transceiver direction adjustment information, the second device will adjust the direction of its acoustic wave receiver or transmitter according to this information. This way ensures that the transmission of the acoustic wave signal is not interfered with and maximizes the quality of signal reception.

[0193] Based on the interaction method described in the above embodiments, the following refers to Figure 6 Describe the logical process of acoustic wave interaction between the first device and the second device.

[0194] Figure 6 is a logical schematic diagram of acoustic wave interaction between the first device and the second device according to an embodiment of the present invention, as Figure 6As shown, assume that the first device is a vehicle and the second device is a charging pile. When it is detected that the vehicle inserts the charging gun, the in-vehicle host in the vehicle can actively detect a sonic wave interaction request. This sonic wave interaction request may include the device identifier (ID) of the charging pile and the data content to be transmitted, that is, the interaction information. The in-vehicle host can transmit the interaction information to the first controller. The first controller encodes the interaction information to generate a sonic wave signal whose sonic wave characteristics match the interaction information, and then generates a corresponding pulse width modulation (PWM) signal based on the sonic wave signal. By transmitting the PWM signal to the inverter, the inverter controls the magnitude and frequency of the current in the first motor stator coil according to the duty cycle of the PWM signal, causing the first motor to generate mechanical vibrations with a specific frequency and loudness, thereby emitting a first sonic wave signal containing the interaction information and realizing the sonic wave transmission of information. The charging pile can capture this sonic wave signal through its built-in sonic wave listening module (such as a microphone) and perform parsing processing on the first sonic wave signal to extract the interaction information, thereby realizing data interaction between the vehicle and the charging pile.

[0195] Based on the interaction method described in the above embodiment, the following refers to Figure 7 Describe the process of the sonic wave payment method, in which the first sonic wave signal sent by the first device is decoded in the second device.

[0196] Figure 7 is a flowchart of the sonic wave payment method according to an embodiment of the present invention, as Figure 7 shown, the process of the sonic wave payment method at least includes steps S100 - S106.

[0197] S100, the first device actively detects a sonic wave interaction request or receives a sonic wave interaction request through an application programming interface.

[0198] S101, the first controller obtains the interaction request and obtains the interaction information required for the transaction activity.

[0199] S102, the first controller transmits the interaction information to the terminal device, and presents the confirmation information containing the interaction information to the user through the terminal device for confirmation.

[0200] S103, after the user confirms, the authentication passes, and the system sorts out the interaction information to be sent and transmits it to the first controller.

[0201] S104, the first controller encodes the interaction information to obtain a sonic wave signal whose sonic wave characteristics match the interaction information, generates an inverter control signal based on the sonic wave signal, and drives the first motor to emit the first sonic wave signal through the inverter based on the inverter control signal.

[0202] S105, The second device receives the first acoustic wave signal containing the interaction information and performs a decoding operation to obtain the interaction information, and sends the interaction information to the transaction settlement platform for settlement.

[0203] S106, The transaction settlement platform completes the settlement and the transaction is completed.

[0204] In some embodiments, if the first device is a vehicle and the second device is a charging pile, when the program in the vehicle host actively detects an acoustic wave interaction request, or when the charging pile sends an acoustic wave interaction request to the vehicle by calling a preset API interface, the vehicle host will start relevant processing. After receiving the interaction request, the vehicle host will extract the interaction information related to the transaction activity. The interaction information includes, but is not limited to: key information required for transactions such as payment method, payment amount, commodity name, commodity number, transaction serial number, payment channel, payment status, buyer token, etc. Then, the confirmation information containing the interaction information is presented to the user through the terminal device (such as the in-vehicle central control screen, instrument panel, HUD, etc.) for confirmation. When the user clicks to confirm, the authentication passes, and the vehicle system sorts out the interaction information to be sent and transmits it to the first controller. The first controller encodes the interaction information to obtain an acoustic wave signal with the acoustic wave characteristics matching the interaction information, generates an inverter control signal based on the acoustic wave signal, and drives the first motor to emit the first acoustic wave signal based on the inverter control signal. The charging pile receives the first acoustic wave signal containing the interaction information and performs a decoding operation to obtain the interaction information, and sends the interaction information to the transaction settlement platform for settlement. The transaction settlement platform performs a payment deduction operation according to the received interaction information and returns the transaction result (such as payment success, payment failure, etc.) to the charging pile. The charging pile feeds back the payment result to the vehicle to complete the transaction process.

[0205] Based on the interaction method described in the above embodiments, the following refers to Figure 8 Describe the interaction logic between the first device, the second device and the server.

[0206] Figure 8 is a flowchart of the interaction logic between the first device, the second device and the server according to an embodiment of the present invention, as Figure 8As shown, if the first device is a vehicle and the second device is a charging pile, the vehicle host, multimedia device, or other display device with an operating system in the vehicle can initiate relevant transaction requests, including key information such as the commodity information purchased by the user and the payment amount. This means that the vehicle is the data source of the entire transaction process. It is responsible for collecting and sending relevant information, that is, interaction information. Then, the interaction information is sent to the first controller in the first device (vehicle). The first controller encodes the interaction information to obtain a sound wave signal whose sound wave characteristics match the target interaction information, and then generates a corresponding pulse width modulation (PWM) signal based on the sound wave signal. By transmitting the PWM signal to the inverter, the inverter controls the magnitude and frequency of the current in the first motor stator coil according to the duty cycle of the PWM signal, causing the first motor to generate mechanical vibrations with a specific frequency and loudness, thereby emitting the first sound wave signal containing the interaction information.

[0207] Further, the second device (charging pile) can capture the first sound wave signal containing the interaction information through its built-in sound wave listening module (such as a microphone), and perform processing such as enhancement, filtering, and noise reduction on the first sound wave signal. Furthermore, it extracts an effective sound wave signal from the ambient noise, filters out interference signals, and performs analog-to-digital conversion to generate a digital sound wave signal sequence. Among them, the device for processing the first sound wave signal can include one or more general microprocessors, application-specific integrated circuits, application-specific instruction set processors, graphics processing units, logic units, coprocessors, digital signal processing units, audio processing units, etc.

[0208] Further, the second controller decodes the first sound wave signal to obtain the interaction information. Then the second controller sends a fifth sound wave signal containing the confirmation information corresponding to the interaction information to the first device (vehicle). The first controller of the first device vehicle decodes the fifth sound wave signal to obtain the confirmation information corresponding to the interaction information, and presents the confirmation information containing the interaction information to the user through the terminal device for confirmation.

[0209] Further, after the user confirms, the first controller may jointly encode the confirmation instruction for the user and the device information of the first device (or separately encode and send a sound wave signal), generate a third sound wave signal, and send the signal to the second device (charging pile). The second controller may convert the third sound wave signal into an electrical signal and send it to the server through the first communication module for parsing. The server can restore the interaction information through the parsing operation. The interaction information includes transaction information and authentication information. According to the authentication information, the server authenticates the first device. After the authentication passes, the server may call a preset payment channel interface or upload relevant transaction information to a third-party transaction settlement platform for payment deduction or order processing. After completing the settlement transaction, the server sends the transaction result and the authentication result back to the second device (charging pile). The second controller in the second device (charging pile) encodes the transaction result and returns it to the first device (vehicle) in the form of a sound wave signal (i.e., the second sound wave signal). At the same time, the second controller may also encode the authentication result and return it to the first device (vehicle) in the form of a sound wave signal (i.e., the fourth sound wave signal). The first controller in the vehicle can extract and analyze the sound wave characteristic value by decoding the signal, thereby obtaining the transaction result and the authentication result, and further display the transaction result and the authentication result on the in-vehicle screen for the user to view.

[0210] Based on the interaction method described in the above embodiment, the following refers to Figure 9 Describe the interaction logic among the first device, the second device, and the third device.

[0211] Figure 9 is a flowchart of the interaction logic among the first device, the second device, and the third device according to an embodiment of the present invention. As Figure 9 shown, if the first device is a vehicle, the second device is a charging pile, and the third device is a camera, when the program in the host of the first device (vehicle) actively detects a sound wave interaction request, or when the second device (charging pile) sends a sound wave interaction request to the vehicle by calling a preset API interface, the first controller in the first device (vehicle) can obtain the interaction request, obtain the interaction information according to the interaction request, encode the interaction information by the first controller to obtain a sound wave signal whose sound wave characteristics match the target interaction information, and then generate a corresponding pulse width modulation (PWM) signal based on the sound wave signal. By transmitting the PWM signal to the inverter, the inverter controls the magnitude and frequency of the current in the first motor stator coil according to the duty cycle of the PWM signal, so that the first motor generates mechanical vibrations with a specific frequency and loudness, thereby emitting a first sound wave signal containing the interaction information. The sound wave signal may have no specific propagation direction. Of course, if there is a need, a specific automotive structure may also be used to make the motor emit the sound wave signal for directional propagation.

[0212] Further, the second device (charging pile) can capture the acoustic wave signal containing the interaction information through its built-in acoustic wave listening module (such as a microphone), and perform processing such as enhancement, filtering, and denoising on the first acoustic wave signal, so as to extract the effective acoustic wave signal from the ambient noise, filter out the interference signal, and perform analog-to-digital conversion to generate a digital acoustic wave signal sequence. Then, a decoding operation is performed on the first acoustic wave signal containing the interaction information to obtain the interaction information.

[0213] Further, after the second device (charging pile) completes the reception and parsing of the interaction information, to ensure that the transaction behavior is initiated by the authorization of a legitimate user and to avoid misoperation or unauthorized automatic transactions, a confirmation information will be generated, and the confirmation information and the interaction information will be encoded to generate the corresponding fifth acoustic wave signal, which is sent to the first device (vehicle). After receiving the fifth acoustic wave signal, the first device (vehicle) presents the confirmation information containing the interaction information to the user for confirmation through the terminal device. When the user checks that the transaction details are correct, the user can click the "Confirm" button on the interface of the terminal device. The first device (vehicle) will then combine and encode the user confirmation instruction and the interaction information, and modulate them into an acoustic wave signal for transmission. The second device (charging pile) will obtain the acoustic wave signal containing the confirmation instruction, decode it to obtain the confirmation instruction and the interaction information, and upload the interaction information to the server. According to the transaction information in the interaction information, the server calls the transaction settlement platform to perform transaction settlement processing.

[0214] Further, the third device (camera) can collect the image information of the vehicle through the internal image acquisition module, and use the image recognition algorithm to analyze the image, extract the recognizable features of the vehicle, so as to further obtain the device information of the vehicle. The device information may include, but is not limited to: the license plate information of the vehicle, the vehicle type information, etc. Through the recognized license plate information and vehicle type information, the corresponding vehicle registration information is further retrieved or matched, such as the payment information of the vehicle owner, the bound payment channels, etc. Based on the above vehicle information, an identity recognition code uniquely corresponding to the first device can be generated, and the license plate information, vehicle type information, payment information, bound payment channels, and identity recognition code are combined to generate the authentication information of the first device (vehicle). The authentication information will then be sent to the second device (charging pile) for subsequent authentication in the server.

[0215] Further, the server will authenticate the first device (vehicle) based on the received authentication information, including verifying data integrity, validating transaction legality, identifying the identity of the transaction user, etc., so as to prevent information forgery or tampering. When the server completes the authentication process, the second controller receives the authentication result sent by the server. The authentication result may include information such as "authentication successful" or "authentication failed". The second controller can encode the authentication result to generate the second feedback information. The second controller controls the acoustic wave emission module to emit a fourth acoustic wave signal containing the second feedback information to the vehicle. The first acoustic wave receiving module in the first device (vehicle) can receive the fourth acoustic wave signal containing the second feedback information and convert the collected analog acoustic wave signal into a digital signal. The decoding module built in the first controller can demodulate and restore the received fourth acoustic wave signal based on a preset decoding rule, extract the valid second feedback information therefrom, and display it in real time on the terminal device or announce the authentication result through voice broadcast.

[0216] Meanwhile, the second controller can also receive the transaction result sent by the server. The transaction result may include information such as "transaction successful" or "transaction failed". The second controller can encode the transaction result to generate the first feedback information. The second controller controls the acoustic wave emission module to emit a second acoustic wave signal containing the first feedback information to the first device (vehicle). The first acoustic wave receiving module in the vehicle can receive the second acoustic wave signal containing the first feedback information and convert the collected analog acoustic wave signal into a digital signal. The decoding module built in the first controller can demodulate and restore the received second acoustic wave signal based on a preset decoding rule, extract the valid first feedback information therefrom, and display it in real time on the terminal device or announce the transaction result through voice broadcast to ensure that the user can timely learn about the transaction status.

By executing the interaction method described in the above embodiments, the operation of the first motor 11 can be controlled to make itself start to vibrate, and then a first acoustic wave signal with a specific frequency and a specific loudness is emitted. This signal carries interaction information, thereby enabling the acoustic wave transmission of information. Since this method directly reuses the existing first motor 11 of the first device 1 itself as the source for emitting the acoustic wave signal without the need to additionally configure a dedicated acoustic wave transmitter (such as a speaker or an ultrasonic module), it can effectively reduce the dependence on external hardware devices and lower the overall hardware complexity and cost of the system. In addition, since the first motor 11 itself is the original standard configuration of the first device 1, its stability and reliability have been fully verified. Its position is relatively fixed, its environmental adaptability is strong, and it is not easily damaged by the external environment, avoiding the risk of damage to the independent acoustic wave transmitting device in the prior art under the external environment, thereby improving the reliability of the interaction.

[0259] In some embodiments, the first device 1 further includes an inverter 13. The inverter 13 is connected to the first motor 11 and the first controller 12 and is configured to drive the first motor 11 to emit an acoustic wave signal.

[0260] Specifically, the in-vehicle host in the first device 1 can actively monitor whether there is a sonic interaction request from the second device 2. The sonic interaction request may include the device identifier (ID) of the second device 2 and the data content to be transmitted, that is, the interaction information. The in-vehicle host can transmit the interaction information to the first controller 12. The first controller 12 encodes the interaction information to generate a sonic signal whose sonic characteristics match the interaction information, and then generates a corresponding pulse width modulation (PWM) signal based on the sonic signal. By transmitting the PWM signal to the inverter 13, the inverter 13 controls the magnitude and frequency of the current in the first motor stator coil according to the duty cycle of the PWM signal, so that the first motor 11 generates mechanical vibrations with a specific frequency and loudness, thereby emitting a first sonic signal containing the interaction information and realizing the sonic transmission of information.

[0261] In some embodiments, the first device 1 further includes: a first sonic receiving module 14, configured to receive a second sonic signal containing first feedback information and / or receive a fourth sonic signal containing second feedback information, where the first feedback information includes a transaction result and the second feedback information includes an authentication result.

[0262] Wherein, the first sonic receiving module 14 can be any sonic receiving device installed on the electric vehicle, such as a built-in microphone, an external microphone, a specific frequency sonic induction device, etc.

[0263] In some embodiments, the first sonic receiving module 14 is capable of collecting the second sonic signal containing the first feedback information and / or receiving the fourth sonic signal containing the second feedback information, and converting the collected analog sonic signal into a digital signal for subsequent processing. The decoding module built in the first device 1 can demodulate and restore the received second sonic signal and / or fourth sonic signal based on a preset decoding rule, and extract the first feedback information and / or the second feedback information therefrom.

[0264] In some embodiments, the first device 1 further includes: a terminal device 15, where the terminal device 15 is connected to the first controller 12 and is used to interact with the user to obtain a confirmation instruction from the user for the interaction information.

[0265] Wherein, the terminal device 15 can be an in-vehicle central control screen, an instrument panel, a voice interaction module, or a HUD, etc., and is presented to the user in a graphical and vocalized manner through the terminal device 15 of the first device 1, so as to improve the interaction transparency and user experience.

[0266] In some embodiments, the first device 1 includes a vehicle. The vehicle can be an active or passive party for sonic interaction and can perform information interaction with second devices including charging piles, parking gates, gas station terminals, access control systems, unmanned stores, etc.

[0267] Next, refer toFigure 16 Describing a second device according to an embodiment of the present invention, the second device may be a charging pile, a parking gate, a gas station terminal, an access control system, etc.

[0268] Figure 16 is a block diagram of a second device according to an embodiment of the present invention, as Figure 16 shown, the second device 2 of the embodiment of the present invention includes: a second sound wave receiving module 21 and a second controller 22.

[0269] In some embodiments, the second sound wave receiving module 21 may be a microphone array or a sound wave sensor, and is used to receive a first sound wave signal. The first sound wave signal is emitted by the first motor 11 of the first device 1, and the first sound wave signal contains interaction information.

[0270] In some embodiments, the controller 22 is connected to the second sound wave receiving module 21, and is used to execute the interaction method described in the above embodiments, and is responsible for receiving the signal from the second sound wave receiving module 21 and performing corresponding processing operations.

[0271] According to the interaction method of the embodiment of the present invention, the second sound wave receiving module 22 is used to receive the first sound wave signal, and the first sound wave signal is emitted by the first motor 11 of the first device 1. Specifically, after the first controller 12 obtains an interaction request, the first controller 12 controls the first motor 11 to run, so that it starts to vibrate itself, and then emits a first sound wave signal with a specific frequency and a specific loudness. This signal carries interaction information, thereby enabling the acoustic transmission of information. Since this method directly reuses the existing first motor 11 of the first device 1 itself as the emission source of the sound wave signal, without the need to additionally configure a dedicated sound wave emitter (such as a speaker or an ultrasonic module), it can effectively reduce the dependence on external hardware devices, reduce the overall hardware complexity and cost of the system. In addition, since the first motor 11 itself is the original standard configuration of the first device 1, its stability and reliability have been fully verified, its position is relatively fixed, its environmental adaptability is strong, and it is not easily damaged by the external environment, avoiding the risk of damage to the independent sound wave emission device in the external environment in the prior art, thereby improving the reliability of the interaction.

[0272] In some embodiments, the second device 2 further includes: a sound wave emission module 23. The sound wave emission module 23 is connected to the second controller 22, and is used to emit at least one of a second sound wave signal containing first feedback information, a fourth sound wave signal containing second feedback information, and a fifth sound wave signal, where the first feedback information includes a transaction result, the second feedback information includes an authentication result, and the fifth sound wave signal contains confirmation information corresponding to the interaction signal.

[0273] In some embodiments, the acoustic wave emission module 23 may include, but is not limited to, an acoustic wave oscillator, a speaker, and a signal modulator. Among them, the acoustic wave oscillator may be responsible for generating vibrations at a specific frequency, the speaker may convert an electrical signal into an acoustic wave signal, and the signal modulator may be used to encode feedback information into an acoustic wave signal suitable for transmission.

[0274] In some embodiments, the second device 2 further includes: a first communication module 24, which is connected to the second controller 22 and is used to communicate with the server 4 or the third device 3.

[0275] In some embodiments, the first communication module 24 may establish a connection with the server 4 or the third device 3 through standard wireless communication protocols (such as Wi-Fi, Bluetooth, 4G / 5G, etc.). Through this communication, the second device 2 can receive authentication information sent by the third device 3, and can send authentication information and interaction information containing transaction information to the server 4. At the same time, the second device 2 can also receive the first feedback information and the second feedback information about the interaction information transmitted by the server 4.

[0276] The following refers to Figure 17 Describe the third device according to an embodiment of the present invention, which is used to communicate with the second device 2 described in the above embodiments. Among them, the third device may be an image acquisition device such as a camera.

[0277] Figure 17 is a block diagram of the third device according to an embodiment of the present invention, as Figure 17 shown, the third device 3 according to the embodiment of the present invention includes: an image acquisition module 31, an image processing module 32, and a second communication module 33.

[0278] In some embodiments, the image acquisition module 31 may be a camera or other type of image sensing device, which is used to acquire image information of the first device 1, where the first device 1 is a device for sending the first acoustic wave signal of the interaction information.

[0279] In some embodiments, the image acquisition module 31 may further determine whether the range where the first device 1 is located is within the recognition area of the second device 2. By identifying the position where the first device 1 is located, it can be used to adjust the direction of the acoustic wave emission module 23 or the acoustic wave reception module 21 of the second device 2 to improve the success rate of acoustic wave interaction.

[0280] In some embodiments, the image processing module 32 is connected to the image acquisition module 31 and is used to execute the interaction method described in the above embodiments. Specifically, device information in the image is extracted through image recognition technology. These device information include, but are not limited to: the device ID, device model, manufacturer information, device configuration, etc. of the first device 1. In order to extract useful device information from the image, the image processing module 32 can use some image processing algorithms, such as feature matching, template recognition, OCR (Optical Character Recognition) technology, machine learning methods, etc. Through these technologies, the image processing module 32 can accurately identify and extract the device information of the first device 1.

[0281] In some embodiments, the second communication module 33 is connected to the image processing module 32 and is used to send the processed authentication information to the second device 2. Specifically, if the first device 1 is a vehicle, through the recognized license plate information and vehicle model information, the corresponding vehicle registration information is further retrieved or matched, such as the payment information of the vehicle owner, the bound payment channels, etc. Based on the above vehicle information, an identity recognition code unique to the first device 1 can be generated, and the license plate information, vehicle model information, payment information, bound payment channels and the identity recognition code are combined to generate the authentication information of the first device 1. This authentication information will then be sent to the second device 2 for subsequent authentication in the server 4.

[0282] In some embodiments, the second communication module 33 can also be used to send acoustic wave transceiver direction adjustment information. Specifically, the third device 3 can send the acoustic wave transceiver direction adjustment information to the second device 2 through wireless communication (such as Wi-Fi, Bluetooth, etc.). After receiving the acoustic wave transceiver direction adjustment information, the second device 2 will adjust the direction of its acoustic wave receiver or transmitter according to this information. This method ensures that the transmission of acoustic wave signals is not interfered with and maximizes the quality of signal reception.

[0283] In some embodiments, the second communication module 33 can support multiple communication protocols, such as Wi-Fi, Bluetooth, Zigbee, etc. It can provide necessary security protection during data transmission. For example, the TLS / SSL protocol is used to encrypt the communication to ensure the privacy and integrity of the data.

[0284] According to a third device 3 of an embodiment of the present invention, an image processing module 32 is connected to an image acquisition module 31. By recognizing the image information of a first device 1 acquired by the image acquisition module 31, device information including a first device identifier or attribute can be extracted, and then authentication information can be generated. The authentication information is sent to a second device 2 through a second communication module 33. This authentication method can effectively prevent interception, replay, or tampering attacks, improving transaction security. Moreover, a first acoustic wave signal including interaction information is generated by a first motor 11 in the first device 1. That is, after a first controller 12 obtains an interaction request, the first controller 12 controls the first motor 11 to operate, causing it to vibrate itself, and then emitting a first acoustic wave signal with a specific frequency and specific loudness. This signal carries the interaction information, thereby enabling acoustic wave transmission of information. Since this method directly reuses the existing first motor 11 of the first device 1 itself as the source for emitting the acoustic wave signal without the need to additionally configure a dedicated acoustic wave transmitter (such as a speaker or an ultrasonic module), it can effectively reduce the dependence on external hardware devices, lowering the overall hardware complexity and cost of the system. In addition, since the first motor 11 itself is an original standard configuration of the first device 1, its stability and reliability have been fully verified. Its position is relatively fixed, and it has strong environmental adaptability and is not easily damaged by external environmental influences, avoiding the risk of damage to an independent acoustic wave emission device in the prior art under external environments, thereby improving the reliability of the interaction.
