Description

Technical Field

[0001] This invention relates to wireless charging technology, and more particularly to an order processing method and system based on wireless charging. Background Technology

[0002] Currently, customers primarily order food at restaurants by scanning a QR code on the table to place their order and make payment. If the restaurant is in an environment with no or weak internet access, the order cannot be completed.

[0003] On the other hand, if information is transmitted using communication methods such as infrared, Bluetooth, Wi-Fi, and UWB, the information transmission is an outward broadcast rather than a point-to-point transmission, which leads to instability and insecurity in the information transmission. Background Technology

[0005] In view of the problems in the prior art, the present invention aims to provide a wireless charging-based order processing method and system that can complete order processing in environments without or with weak network coverage.

[0006] An order processing method based on wireless charging, as described in this invention, is implemented by a merchant's wireless charging device and a user terminal, and includes the following steps:

[0007] The order notification information acquisition step involves the user terminal acquiring the order notification information, which includes the merchant application identifier and the hardware identifier of the merchant's wireless charging device.

[0008] In the order generation step, the user terminal generates order information based on the order prompt information, wherein the order information includes product-related information, the identifier of the user terminal, and the hardware identifier of the wireless charging device;

[0009] In the first transmission step, the user terminal sends the order information to the wireless charging device through the power transmission channel between the wireless charging device and the user terminal; and

[0010] In the second transmission step, the wireless charging device receives the order information from the power transmission channel and sends the order information to the outside via the power line carrier channel.

[0011] An order processing system according to one aspect of the present invention includes: a merchant wireless charging device and a user terminal. The merchant wireless charging device is used to determine whether wireless charging has occurred and, if wireless charging has occurred, to send an order intention request to the user terminal via a power transmission channel. The order intention request information includes at least a merchant application identifier. After receiving an order intention confirmation from the user terminal, the merchant wireless charging device is used to send an order prompt to the user terminal. The order prompt includes the merchant application identifier and the hardware identifier of the merchant wireless charging device. Upon receiving order information from the user terminal, the merchant wireless charging device... The device is used to verify order information and transmit the order information to an external device via power line carrier technology. The user terminal is used to receive the order intention request information from the merchant's wireless charging device, generate order intention confirmation information based on the order intention request information, and send the order intention confirmation information to the merchant's wireless charging device. The user terminal is also used to receive order prompt information from the merchant's wireless charging device, generate order information based on the order prompt information, and send the order information to the merchant's wireless charging device. The order information includes a user identifier, a hardware identifier of the user terminal, a hardware identifier of the merchant's wireless charging device, and product-related information.

[0012] According to the order processing method and system based on wireless charging of the present invention, during the user's dining process, ordering and payment can be completed in environments without or with weak network connectivity while the user's terminal is wirelessly charged. Furthermore, the order intention recognition can be completed through the wireless charging module in the user's terminal, and the transmission information can be transmitted to the merchant's wireless charging device via the wireless charging module in the user's terminal. This enables directional transmission of the user's terminal's communication signals, improving the user's dining and payment experience, and enhancing the security of signal transmission.

[0016] The following are some embodiments of the present invention, intended to provide a basic understanding of the invention. They are not intended to identify key or decisive elements of the invention or to limit the scope of protection sought.

[0017] For purposes of brevity and illustrativeness, the principles of the invention are described herein primarily with reference to exemplary embodiments thereof. However, those skilled in the art will readily recognize that the same principles are equivalently applicable to all types of wireless charging-based order processing methods and systems, and that these same principles can be implemented therein, with any such variations not departing from the true spirit and scope of this patent application.

[0018] Furthermore, reference is made in the following description to the accompanying drawings, which illustrate specific exemplary embodiments. Electrical, mechanical, logical, and structural modifications may be made to these embodiments without departing from the spirit and scope of the invention. Moreover, while features of the invention are disclosed in conjunction with only one of several embodiments, this feature may be combined with one or more other features of other embodiments if desired and / or advantageous for any given or identifiable function. Therefore, the following description should not be considered limiting in any sense, and the scope of the invention is defined by the appended claims and their equivalents.

[0019] Terms such as “comprising” and “including” indicate that, in addition to having units (modules) and steps that are directly and explicitly stated in the specification and claims, the technical solution of the present invention does not exclude the presence of other units (modules) and steps that are not directly or explicitly stated.

[0020] First, the order processing method based on wireless charging of the present invention will be described. The order processing method based on wireless charging of the present invention is achieved through data interaction between a merchant's wireless charging device and a user terminal using the wireless charging device for charging.

[0021] The order processing method based on wireless charging of the present invention can be roughly divided into two stages:

[0022] (a) Obtaining order information during wireless charging mainly includes: the user terminal obtaining order prompt information, and the user terminal generating order information based on the order prompt information;

[0023] (ii) Transmission of order information between the merchant wireless charging device and the user terminal mainly includes: the user terminal sending order information to the merchant wireless charging device through the power transmission channel between the wireless charging device and the user terminal, and the merchant wireless charging device receiving the order information from the power transmission channel.

[0024] Next, these two stages will be explained separately.

[0025] Obtain order information during wireless charging.

[0026] Obtaining order information during wireless charging mainly includes: the user terminal obtaining order prompt information, and the user terminal generating order information based on the order prompt information. The order information includes product information, the identifier of the user terminal, and the hardware identifier of the wireless charging device.

[0027] There are two ways to obtain order information during wireless charging: (1) passive push order; and (2) active scan order.

[0028] (1) Passive push order placement.

[0029] When a merchant's wireless charging device detects that a user's terminal is wirelessly charging, the device sends an order intention prompt to the user's terminal. The user then confirms their order intention based on this prompt (this confirmation involves changing the user's terminal's position / time of arrival to alter the current received by the wireless charging device, such as by rapidly approaching the device twice or placing it in a specific location for a period of time). At this point, the receiving current of the wireless charging device changes. Based on the frequency of this current change and the duration the current remains at a certain value, the merchant's wireless charging device can determine the user's order intention.

[0030] After the user confirms their order intention, the user terminal sends an order intention confirmation message to the merchant's wireless charging device. Upon receiving the order intention confirmation message, the merchant's wireless charging device sends an order prompt message to the user terminal (e.g., including the merchant's application identifier, the hardware identifier of the merchant's wireless charging device, etc.). The user terminal receives the order prompt message and calls the corresponding merchant application (or merchant's WeChat mini-program, etc.) based on the merchant's application identifier. The user terminal generates order information based on the order prompt message, wherein the order information includes product-related information (product information, transaction amount, etc.), the user terminal's identifier, and the hardware identifier of the wireless charging device.

[0031] (2) The main scan places an order.

[0032] When the user terminal is wirelessly charging, the user terminal scans the merchant's order QR code. The order QR code contains the merchant application identifier, the hardware identifier of the merchant's wireless charging device, and the order prompt message. The user terminal opens the corresponding merchant application (or merchant's WeChat mini program) based on the merchant application identifier to place an order and generate order information.

[0033] After an order is placed, when the user terminal detects that wireless charging is in progress, it sends order information (e.g., including user identifier, user terminal hardware identifier, order amount, product information, and merchant wireless charging device hardware identifier) ​​from the user terminal to the merchant wireless charging device. Upon receiving the order information, the merchant wireless charging device checks if the hardware identifier in the received order information matches. If they match, it performs subsequent order forwarding operations (e.g., sending the order information from the wireless charging device to the merchant's edge computing gateway).

[0034] a) Transmitting order information between the merchant's wireless charging device and the user terminal

[0035] The transmission of order information between the merchant's wireless charging device and the user terminal includes two aspects: (1) transmitting information from the merchant's wireless charging device to the user terminal; and (2) transmitting information from the user terminal to the merchant's wireless charging device.

[0036] Before explaining the transmission of order information between the merchant's wireless charging device and the user terminal, the wireless charging-based order processing system of the present invention will be described first.

[0037] Figure 1 This is a schematic diagram illustrating the structure of the wireless charging-based order processing system of the present invention.

[0038] like Figure 1 As shown, the wireless charging-based order processing system of the present invention includes a merchant wireless charging device 100 and a user terminal 200 (the user terminal 200 specifically refers to the wireless charging module of the user terminal).

[0039] Merchant wireless charging device 100 includes:

[0040] Inverter 101 is used to convert DC current into AC signal through high-frequency inversion;

[0041] The first signal input module 102 is used to digitize the input signal to obtain a digital signal;

[0042] The first modulation circuit 103 is used to modulate the digital signal to generate a carrier signal;

[0043] The first resonant circuit 104 is used to form an electrical wave from an alternating current signal and to load a carrier signal onto the electrical wave and provide it to the transmitting coil 105. On the other hand, it is also used to receive the electrical wave from the transmitting coil 105 and convert the electrical wave into an alternating current signal.

[0044] The transmitting coil 105 is used to transmit the electrical energy wave output by the first resonant circuit 104 and also to receive the electrical energy wave from the receiving coil 201.

[0045] The first signal extraction module 106 is used to extract the carrier signal from the AC signal converted by the first resonant circuit 104.

[0046] The first demodulation circuit 107 is used to demodulate the carrier signal extracted by the first signal extraction module 106;

[0047] The first information processing module 108, the functions of which will be described in detail later.

[0048] User terminal 200 includes:

[0049] The receiving coil 201 is used to receive electrical energy waves from the transmitting coil 105 and also to transmit electrical energy waves output by the second resonant circuit 202.

[0050] The second resonant circuit 202 is used to receive the electrical energy wave from the receiving coil 201 and convert it into an alternating current signal. On the other hand, it also forms the alternating current into an electrical energy wave and loads a carrier signal onto the electrical energy wave to provide it to the receiving coil 201.

[0051] The second signal extraction module 203 is used to extract the carrier signal from the electrical energy wave received by the second resonant circuit 202;

[0052] The second demodulation circuit 204 is used to demodulate the carrier signal extracted by the second signal extraction module 203;

[0053] The rectifier and voltage regulator circuit 205 is used to convert the AC signal output by the second resonant circuit 202 into a DC signal and provide it to the load battery of the user terminal after voltage regulation.

[0054] The second signal input module 206 is used to digitize the input signal to obtain a digital signal.

[0055] The second modulation circuit 207 is used to modulate the digital signal and generate a carrier signal; and

[0056] The second information processing module 208, the functions of which will be described in detail later.

[0057] (1) Transmitting information from the merchant’s wireless charging device to the user terminal.

[0058] The first signal input module 102 of the merchant's wireless charging device sends the information to be transmitted to the first modulation circuit 103. The first modulation circuit 103 sends the information to be transmitted to the first resonant circuit 104. The first resonant circuit 104 processes the received information to be transmitted, loads the information onto the power transmission channel, and then transmits the information to the user terminal 200 through the transmitting coil 105. After receiving the power, the receiving coil 201 transmits the information to the second resonant circuit 202. The information is extracted by the second signal extraction module 203 and then demodulated by the second demodulation circuit 204 to obtain the transmission information.

[0059] The transmission of information from a merchant's wireless charging device to a user terminal is called "forward signal transmission," and its principle is as follows:

[0060] The information to be transmitted is simulated into a digital signal (0-1 form) by the first signal input module 101. The digital signal is modulated by the first modulation circuit 103 to form a carrier signal. The carrier signal is then injected into the electrical wave in the channel by the transformer (located in the first resonant circuit 104). The electrical wave is transmitted to the user terminal 200 through the transmitting coil 105. In the user terminal 200, the receiving coil 201 receives the electrical wave and transmits it to the second resonant circuit 202. The second resonant circuit 202 converts the electrical wave into an electrical signal. The second signal extraction device 203 extracts the carrier signal from the electrical signal, and then the original information is obtained after demodulation by the second demodulation circuit 204.

[0061] (2) Transmit information from the user terminal to the merchant's wireless charging device.

[0062] In the user terminal 200, the information to be transmitted is input into the second signal input module 206. The second signal input module 206 converts the information into a digital signal and sends it to the second modulation circuit 207. The second modulation circuit 207 sends the digital signal to the second resonant circuit 202. The second resonant circuit 202 processes the received digital signal, loads the processed carrier signal onto the power transmission channel, and then sends the carrier signal to the transmitting coil 105 of the merchant wireless charging device 100 through the receiving coil 201. The first signal extraction module 106 extracts the information, and then the information is obtained after demodulation by the first demodulation circuit 107.

[0063] The transmission of information from the user terminal to the merchant's wireless charging device is called "reverse signal transmission," and its principle is as follows:

[0064] The same method as the above-described forward signal transmission can be used, or the following methods can also be used:

[0065] A capacitor is connected in parallel in the second resonant circuit 202 and a switch is added. The switch is opened and closed according to the information transmission, thereby changing the equivalent capacitance of the receiving circuit in the user terminal, realizing the change of the equivalent impedance of the receiving circuit, which in turn causes the change of the reflection impedance and the total impedance of the transmitting circuit. This causes the current change of the transmitting circuit (i.e., the first resonant circuit 104) in the merchant's wireless charging device. The first signal extraction module 106 can extract the signal based on the current change of the first resonant circuit 104.

[0066] After the above two stages (i) and (ii), in order to forward the order to complete the payment process, the merchant's wireless charging device uses power line carrier technology to simulate the order information, including the user identifier and the hardware identifier of the user terminal, into a high-frequency signal and load it onto the power line. The high-frequency signal is then transmitted to the merchant's edge computing gateway through the power line, and the merchant's edge computing gateway sends the information to the merchant's server. Since the power line signal is a low-frequency signal, the high-frequency signal is easier to separate from the power line signal.

[0067] Next, an order processing method based on wireless charging according to one embodiment of the present invention will be described.

[0068] Figure 2 This is a flowchart illustrating an order processing method based on wireless charging according to one embodiment of the present invention.

[0069] like Figure 2 As shown, an embodiment of the order processing method based on a wireless charging device of the present invention utilizes a user terminal (including a wireless charging module), a merchant wireless charging device, a merchant edge computing gateway, a merchant server system, and a payment system. Specifically, an embodiment of the order processing method based on a wireless charging device of the present invention includes the following steps:

[0070] S1: The merchant's wireless charging device determines that wireless charging behavior has occurred. For example, when the merchant's wireless charging device transmits power to the outside, it determines that a user terminal (such as a mobile phone, PAD, etc.) is close by and wireless charging behavior has occurred.

[0071] S2: The merchant's wireless charging device sends an order request to the user terminal through the power transmission channel. This order request information includes at least the merchant application identifier. The merchant's wireless charging device sends the order request to the user terminal through the power transmission channel in the following manner (see reference). Figure 1 illustrate):

[0072] The merchant's wireless charging device inputs the order request information into the first signal input module 102. After being digitized by the first signal input module 102, it is sent to the first modulation circuit 103. The first modulation circuit 103 sends the digitized signal to the first resonant circuit 104. The first resonant circuit 104 processes the digitized signal to generate a carrier signal, loads the carrier signal onto the power transmission channel, and then transmits the information to the user terminal 200 through the transmitting coil 105. The receiving coil 201 in the user terminal 200 receives the information, extracts the information through the second resonant circuit 202, and obtains the information after demodulation by the second demodulation circuit 204.

[0073] S3: The user terminal launches the merchant application (or merchant WeChat mini program, etc.) based on the merchant application identifier, and confirms the order intention according to the prompts. For example, the user taps the merchant's wireless charging device twice quickly, or places it in a designated position on the table for 2 seconds. In this way, the receiving current of the wireless charging module of the user terminal will undergo an adaptive change, that is, the frequency of the receiving current changes, or the receiving current is maintained at a certain value for a period of time. Based on the change of the receiving current of the wireless charging module of the user terminal, the user's order intention can be determined.

[0074] S4: The user terminal sends an order confirmation message to the merchant's wireless charging device. This message may include, for example, data on the received current changes of the user terminal's wireless charging module. Specifically, this is achieved through the following method (see reference). Figure 1 illustrate):

[0075] The user terminal provides the order confirmation information to the second signal input module 206. The second signal input module 206 digitizes the order confirmation information and sends the resulting digital signal to the second modulation circuit 207. The second modulation circuit 207 modulates the digital signal to obtain a carrier signal, which is then sent to the second resonant circuit 202. The second resonant circuit 202 loads the carrier signal onto the power transmission channel and transmits the information to the transmitting coil 105 of the merchant wireless charging device 100 via the receiving coil 201. Thus, the merchant wireless charging device extracts the received information through its first signal extraction module 106 and demodulates it through the first demodulation circuit 107 to obtain the information.

[0076] Alternatively, it can be implemented as follows: a capacitor is connected in parallel in the second resonant circuit 202, and a switch is added. The switch is opened and closed according to the information transmission, thereby changing the equivalent capacitance of the receiving circuit in the user terminal, realizing the change of the equivalent impedance of the receiving circuit, which in turn causes the change of the reflection impedance and the total impedance of the transmitting circuit. This can trigger the current change of the transmitting circuit (i.e., the first resonant circuit 104) in the merchant's wireless charging device. Based on the current change of the first resonant circuit 104, the first signal extraction module 106 extracts the order intention confirmation information.

[0077] S5: After the merchant's wireless charging device receives the order confirmation information from the user terminal, it sends an order prompt message to the user terminal. This message may include, for example, the merchant's application identifier, the hardware identifier of the merchant's wireless charging device, and the order prompt message itself. Furthermore, as a preferred method, the merchant can also verify the user's order confirmation information. Specifically, based on the received current change status data sent by the user terminal, the merchant can detect the transmitted current change data of the merchant's wireless charging device over historical time periods to determine if there is a match. If a match is found, it is determined that the user has the intention to place an order. After successful verification, the merchant then sends the order prompt message to the user terminal.

[0078] S6: After receiving the order prompt information from the merchant's wireless charging device, the user terminal launches the merchant application (or merchant's WeChat mini program) according to the merchant application identifier, places an order for the goods according to the order prompt information, and generates order information.

[0079] S7: The user terminal sends order information to the merchant's wireless charging device. The order information includes, for example, the user identifier, the user terminal's hardware identifier, the merchant application identifier, the merchant's wireless charging device's hardware identifier, and product-related information (order amount, product information), etc.

[0080] S8: The merchant's wireless charging device verifies the order information. This verification can be achieved by determining whether the hardware identifier of the merchant's wireless charging device matches. If the hardware identifier of the merchant's wireless charging device matches in the order information, the verification is successful.

[0081] S9: The merchant's wireless charging device sends order information to the merchant's edge computing gateway. As an example, the merchant's wireless charging device uses power line carrier technology to send order information to the merchant's edge computing gateway.

[0082] S10: The merchant edge computing gateway sends order information to the merchant server system.

[0083] S11: The merchant server system determines the merchant's payment account based on the merchant identifier, and then generates a payment order based on the user identifier, the user terminal's hardware identifier, the merchant identifier, the merchant's payment account, and the order amount.

[0084] S12: The merchant server system sends the payment order to the payment system.

[0085] S13: The payment system determines the user's payment account based on the user identifier in the payment order, and then transfers the funds from the user's payment account to the merchant's collection account to complete the payment processing operation.

[0086] S14: The payment system sends the payment result notification to the merchant's server system.

[0087] S15: The merchant server system sends the payment result notification to the user terminal.

[0088] Let's go back to this point. Figure 1 ,for Figure 1 The functions of the merchant wireless charging device 100 and its first information processing module 108, and the user terminal 200 and its second information processing module 208 are described.

[0089] The merchant wireless charging device 100 performs the following functions: It determines whether wireless charging has occurred. When it determines that the merchant wireless charging device is transmitting power, it is considered that wireless charging has occurred. At this time, it sends an order intention request to the user terminal through the power transmission channel. The order intention request information includes at least the merchant application identifier. After receiving the order intention confirmation information from the user terminal, it sends an order prompt message to the user terminal. The order prompt message includes the merchant application identifier, the hardware identifier of the merchant wireless charging device, and the order prompt message. When order information is received from the user terminal, it verifies the order information. This verification can be achieved by determining whether the hardware identifier of the merchant wireless charging device matches. Finally, it sends the order information to the merchant edge computing gateway via power line carrier technology.

[0090] Specifically, the first information processing module 108 is used to determine whether wireless charging has occurred. When it is determined that the merchant's wireless charging device is transmitting power, the first information processing module 108 generates an order intention request information and sends it to the first signal input module 102. The order intention request information is then transmitted to the user terminal through the power transmission channel via the first signal input module 102, the first modulation circuit 103, the first resonant circuit 104, and the transmitting coil 105. When an order intention confirmation information is received from the user terminal via the transmitting coil 105, the first resonant circuit 104, the first signal extraction module 106, and the first demodulation circuit 107, the first signal... The information processing module 108 generates an order notification message and sends it to the first signal input module 102. The first signal input module 102, the first modulation circuit 103, the first resonant circuit 104, and the transmitting coil 105 transmit the order notification message to the user terminal through the power transmission channel. When the user terminal receives the order information through the transmitting coil 105, the first resonant circuit 104, the first signal extraction module 106, and the first demodulation circuit 107, the first information processing module 108 verifies the order information and, if the verification is successful, transmits the order information to the merchant edge computing gateway through power line carrier technology.

[0091] User terminal 200 mainly performs the following functions: receiving order intention request information and generating order intention confirmation information based on the order intention request information; sending order intention confirmation information to the merchant's wireless charging device; receiving order prompt information from the merchant's wireless charging device and generating order information accordingly; and sending order information to the merchant's wireless charging device, wherein the order information includes user identifier, user terminal hardware identifier, merchant application identifier, merchant wireless charging device hardware identifier, and product information.

[0092] Specifically, the user terminal 200 receives order intention request information from the merchant's wireless charging device through the receiving coil 211, the second resonant circuit 212, the second signal extraction module 213, and the second demodulation circuit 214, and provides it to the second information processing module 208. The user then performs an order intention confirmation operation based on the order intention request information. The second information processing module 208 generates order intention confirmation information and inputs it to the second signal input module 216. The information is then processed by the second modulation circuit 217 of the second signal input module 216 and the receiving coil. 211 is sent to the merchant's wireless charging device. The receiving coil 211, the second resonant circuit 212, the second signal extraction module 213, and the second demodulation circuit 214 receive the order prompt information from the merchant's wireless charging device and provide it to the second information processing module 208. The user places an order according to the order prompt information, and the second information processing module 208 generates order information. The order information is input to the second signal input module 216, and then sent to the merchant's wireless charging device through the second modulation circuit 217 of the second signal input module 216 and the receiving coil 211.

[0093] According to the wireless charging order processing method and system of the present invention, order processing (such as ordering food and making payments) can be completed in environments without a network or with a weak network. That is, it can transmit transmission information from the user terminal (mainly referring to the wireless charging module of the user terminal) to the merchant's wireless charging device without the need for communication network support. Moreover, this information transmission method is point-to-point transmission, which can increase the stability and security of information transmission.

[0094] Furthermore, the order processing method and system for wireless charging of the present invention can complete the identification of order placement intention. For example, by having the user terminal quickly approach the merchant's wireless charging device twice in succession or place it in a certain position for a period of time, the receiving current of the wireless charging device of the user terminal changes. Based on the frequency of the receiving current change and the holding time of the receiving current at a certain value, the merchant's wireless charging device can determine the user's order placement intention.

[0095] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Those skilled in the art can conceive of other feasible variations or substitutions based on the technical scope disclosed in this application, and such variations or substitutions are all covered within the scope of protection of this application. Where there is no conflict, the embodiments and features described in the embodiments of this application can also be combined with each other. The scope of protection of this application is determined by the claims.
