[0001] This application is a divisional application of the invention patent application submitted to the China Patent Office on July 23, 2024, with application number 202410986304.3, and invention name "Interactive processing method, device and near-field communication equipment based on near-field communication". The full text of the application is incorporated into this application by reference. Technical Field

[0002] The present invention relates to the field of near field communication technology, and in particular to an interaction processing method, apparatus and near field communication device based on near field communication. Background Art

[0003] Near Field Communication (NFC) is a short-range, high-frequency radio technology that operates at a frequency of 13.56MHz within a distance of 20cm. It is an integration of contactless radio frequency identification (RFID) and interconnection technology, providing a very safe and fast communication method for various electronic products.

[0004] With the popularization of smartphones that support near-field communication functions, near-field communication technology has also been widely used in areas such as payment. Merchants can use near-field communication devices as cash registers, and users can complete payments by placing their mobile phones close to the merchant's near-field communication devices for inductive communication.

[0005] In the prior art, near-field communication devices need to have larger antennas in order to expand the sensing range. However, as the antenna area increases, the signal strength per unit area decreases, resulting in a decrease in the reading distance. Moreover, the near-field communication antennas of different mobile phones differ in size, location on the phone, antenna status, and power consumption control logic, which will also affect the actual sensing effect of the near-field communication device, and further affect the success rate and efficiency of near-field communication.

[0006] Based on this, there is a need for a solution that helps to improve the success rate and efficiency of near field communication between a merchant's near field communication device and a user's mobile phone. Summary of the invention

[0012] Communication is established with the sensing object through the target near field communication antenna to perform business interaction.

[0013] One or more embodiments of this specification provide an interactive processing device based on near field communication, including:

[0016] The near field communication service interaction module establishes communication with the sensing object through the target near field communication antenna to perform service interaction.

[0018] At least two of the signal sensing antennas are configured to respectively sense a currently approaching sensing object;

[0019] The control chip selects, from the plurality of near field communication antennas, a near field communication antenna that is close to the sensing object as a target near field communication antenna according to a difference in signal strengths sensed by the at least two signal sensing antennas respectively;

[0020] The target near field communication antenna establishes communication with the sensing object to perform business interaction.

[0021] One or more embodiments of this specification provide an interactive processing device based on near field communication, including:

[0022] at least one processor; and,

[0023] a memory communicatively connected to the at least one processor; wherein,

[0024] The memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to execute:

[0025] Through multiple signal sensing antennas deployed on the near field communication device, the currently approaching sensing objects are sensed respectively;

[0046] The embodiments of this specification provide an interaction processing method and apparatus based on near field communication, a near field communication device, and a storage medium.

[0047] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0048] In response to the problems mentioned in the background technology, the present application can achieve performance improvements in the following aspects of near-field communication by splitting the near-field communication antenna for a distributed layout and using the corresponding chip signal processing method: it has the ability to reliably and dynamically expand the sensing distance and sensing range of the near-field communication antenna; it helps to increase the reading success rate and efficiency of near-field communication equipment for different mobile phones, and increase the compatibility of near-field communication equipment for different mobile phones; optionally, it can improve scalability by flexibly plugging and unplugging the antenna to meet performance requirements in different scenarios, while balancing cost control needs.

[0049] Based on this general idea, the solution of this application will be further described below.

[0050] Figure 1 A flowchart of an interactive processing method based on near field communication is provided for one or more embodiments of this specification. The execution subject of the process can be a near field communication device or a module therein. From a software perspective, the execution subject can be an application on the near field communication device, such as a cash register application.

[0051] Figure 1 The process in includes the following steps:

[0052] S102: Using a plurality of signal sensing antennas deployed on the near field communication device, respectively sense the sensing objects currently approaching.

[0053] In one or more embodiments of the present specification, the signal sensing antenna is mainly responsible for inferring the position or direction from which the sensing object approaches the near field communication device through sensing detection, without being responsible for the specific communication establishment and business data transmission between the sensing object and the sensing object. Multiple signal sensing antennas are deployed on the near field communication device, and the signal sensing antennas that sense the sensing object respectively in step S102 can be two or more of the multiple signal sensing antennas. The number of signal sensing antennas that can simultaneously sense the currently approaching sensing object can be affected by controlling the sensing capability of the signal sensing antenna.

[0054] Multiple signal sensing antennas are deployed at different locations on the near-field communication device, and can be deployed in a dispersed manner in particular. This helps to have better sensing capabilities for sensing objects in different directions, thereby increasing the global sensing range and improving reliability. It also reduces the operational requirements for users, and allows users to more freely and arbitrarily bring their mobile phones close to the near-field communication device from more directions for near-field communication interaction.

[0055] S104: According to the difference in signal strengths respectively sensed by the multiple signal sensing antennas, select a near field communication antenna that is close to the sensing object from among the multiple near field communication antennas deployed on the near field communication device as a target near field communication antenna.

[0056] Among the multiple signal sensing antennas that can sense the currently approaching sensing object, the closer the distance to the sensing object and / or the more accurately the antenna direction is aligned with the approaching direction of the sensing object, the more likely it is to sense a greater signal strength. By properly deploying the multiple signal sensing antennas at different positions on the near field communication device, it is possible that, at least in most cases, the signal strengths sensed by them for the sensing object are different. Based on such differences, through operations such as three-point positioning, at least the approaching direction of the sensing object can be roughly inferred, and it is even possible to more accurately infer the dynamic relative position of the sensing object to the near field communication device.

[0057] For example, the sensing object can be located based on the differences in signal strengths sensed by at least three signal sensing antennas deployed at different locations. The positions of the near-field communication antennas are known to the near-field communication device, so the near-field communication antenna that is close to the sensing object can be screened from the multiple near-field communication antennas deployed on the near-field communication device.

[0058] In one or more embodiments of the present specification, similar to the signal sensing antenna, multiple near-field communication antennas are deployed at different locations on the near-field communication device, and can be deployed in a dispersed manner, so that it is also easy to distinguish the distance, making it easier to screen out the target near-field communication antenna with more prominent advantages in different directions. For near-field communication antennas that are relatively closer to the sensing object (especially the closest distance), there is a greater probability that they can establish communication with the sensing object more efficiently and reliably, so such near-field communication antennas can be preferentially selected as target near-field communication antennas.

[0059] It should be noted that in actual applications, distance can be used as an active screening factor. At the same time, if necessary, other factors other than distance (such as antenna direction, working power, idleness, etc.) can be combined to screen near-field communication antennas. In this case, the final target near-field communication antenna may not be the near-field communication antenna closest to the sensing object, but a near-field communication antenna with a closer distance and a higher ranking.

[0060] Furthermore, the present application hopes to use the signal sensing antenna as the vanguard, so that it can sense and detect the sensing object as early as possible before the near-field communication antenna. Therefore, the signal sensing antenna can be given an advantage in position. For example, multiple signal sensing antennas deployed on the near-field communication device can be deployed dispersedly on the outside. Similarly, multiple near-field communication antennas deployed on the near-field communication device can be deployed dispersedly on the inside. Such deployment also has advantages, including avoiding large antennas, and there is enough space on the outside to deploy more signal sensing antennas (if necessary), thereby effectively improving the global sensing capability and avoiding the generation of a large range of sensing blind spots.

[0061] S106: Establishing communication with the sensing object through the target near field communication antenna to perform business interaction.

[0062] In one or more embodiments of this specification, the near-field communication antenna is mainly used to establish communication with the sensing object and conduct subsequent business interaction. Its task is relatively more complex. Compared with the near-field communication antenna, the signal sensing antenna can be implemented more lightweight and at a lower cost. In terms of quantity, the number of signal sensing antennas deployed on the near-field communication device can also be greater than the number of near-field communication antennas. In this way, while ensuring the sensing capability and subsequent formal interaction capability, it is possible to take into account the cost requirements.

[0063] Devices that support NFC (including the NFC devices and mobile phones mentioned above) can use either card emulation mode or card reader mode. For card emulation mode, the device is used as an IC card using RFID technology for reading by a card reader. For card reader mode, the device is used as a card reader, for example, it can read relevant information from IC cards, posters or exhibition information electronic tags using RFID technology.

[0064] In traditional technology, taking the payment field as an example, the merchant's near-field communication payment device adopts a card reader working mode, acting as a card reader, and the user's mobile phone adopts a card simulation working mode, simulating a credit card or debit card. The user can achieve an effect similar to card payment by placing the mobile phone close to the payment device for sensing interaction; however, in actual applications, the above interaction method may have compatibility issues, such as compatibility issues between some applications and mobile phone manufacturers, etc., which brings unreliable factors to the above interaction and may even affect the normal development of some businesses.

[0065] Based on this, we consider breaking through the limitations of traditional thinking, and the merchant's near-field communication device is no longer limited to the card reader working mode, but is also compatible with the card simulation working mode in business, and can give priority to the card simulation working mode to interact with the user's mobile phone. In this case, for step S106, after establishing communication with the sensing object (such as a mobile phone) through the target near-field communication antenna, assuming that the payment business interaction is carried out, then specifically, for example, the merchant's near-field communication device acts as a simulated card and generates information to be paid, so that the user's mobile phone, which is the sensing object, acts as a card reader, reads the simulated card to obtain the information to be paid, and pays according to the information to be paid (such as the user confirms the payment of the order on the mobile phone).

[0066] pass Figure 1The method is used to split the antenna of the near-field communication device from the functional and hardware levels, and create an architecture in which multiple signal sensing antennas work together with multiple near-field communication antennas. The multiple signal sensing antennas are mainly used to sense the sensing object (for example, a mobile phone) to determine which near-field communication antenna is closer to the currently approaching sensing object, and then this near-field communication antenna is used to establish communication with the sensing object for business interaction. In this way, the signal sensing antenna can be designed to be more lightweight and dispersedly deployed on the near-field communication device, effectively expanding the sensing distance and sensing range while helping to balance the cost. The near-field communication antenna can also be appropriately dispersedly deployed (optionally, the near-field communication antenna can be reduced to further reduce the cost without affecting the sensing), focusing on establishing communication, and achieving each time's selection by cooperation with the signal sensing antenna (that is, each time the communication is established by the near-field communication antenna with better expected effect), which helps to more efficiently and successfully communicate with various sensing objects in the near-field, with better compatibility and better experience for merchants and users.

[0067] based on Figure 1 This specification also provides some specific implementation plans and extension plans of the method, which will be described below.

[0068] In one or more embodiments of the present specification, for a currently approaching sensing object, a target near-field communication antenna will be screened out from multiple near-field communication antennas for further establishing communication, and according to the previous description, compared with the position of the signal sensing antenna, the near-field communication antenna can preferably be deployed at a more inward position. Taking this into account, in order to enable the target near-field communication antenna to establish communication more reliably and efficiently, while helping to save resources from a global perspective, it is possible to consider temporarily strengthening the performance of the target near-field communication antenna, and optionally reducing the performance of other near-field communication antennas. Based on this idea, one or more embodiments of the present specification provide a process for a near-field communication range dynamic control solution, Figure 2 is a schematic diagram of the process, in which the antenna performance is mainly demonstrated from the perspective of the transmission signal or the control signal.

[0069] Figure 2 The process in includes the following steps:

[0070] S202: Selecting a near field communication antenna close to the sensing object from among multiple near field communication antennas deployed on the near field communication device as a target near field communication antenna, and controlling a signal enhancement of the target near field communication antenna.

[0071] After the signal (such as the transmission signal) of the target near field communication antenna is enhanced, it is easier to establish communication with the sensing object and helps to maintain the stability of subsequent communication. After the communication is completed, the signal of the target near field communication antenna can be restored in time to avoid possible impact on the signal sensing antenna or other near field communication antennas.

[0072] The specific degree of signal enhancement of the target near-field communication antenna can be determined based on the actual situation. For example, if the signal strength sensed by the signal sensing antenna for the sensing object is relatively low, the signal strength of the target near-field communication antenna can be enhanced relatively higher. Otherwise, the degree of enhancement can be not so high. In this way, the near-field communication range can be adaptively and flexibly controlled in conjunction with the signal sensing antenna to better accommodate sensing objects with different performances, so that users can obtain a more consistent and good experience.

[0073] S204: temporarily turning off control signals of the multiple near field communication antennas except the target near field communication antenna, or temporarily reducing or turning off signals of the multiple near field communication antennas except the target near field communication antenna.

[0074] Through the operation of step S204, the performance of other near-field communication antennas can be temporarily suppressed, thereby further highlighting the current dominant position of the target near-field communication antenna, so that the sensing object can more accurately dock with the target near-field communication antenna, and reduce global resource consumption. After the communication is completed, the performance of other near-field communication antennas can be restored in time. According to a similar idea, in normal use, multiple near-field communication antennas can also be controlled to dynamically reduce the performance of some near-field communication antennas in turn.

[0075] As mentioned above, the present application considers making the merchant's near-field communication device adopt the card simulation working mode as much as possible, and the user's mobile phone as the sensing object adopts the card reader mode. During in-depth testing, the applicant discovered the problems that may be caused by the low-power mode, including that the near-field communication signal of the user's mobile phone may enter the low-power mode to save resources. In this case, when performing traditional near-field communication interactions, even in low-power mode, if the mobile phone adopts the card simulation working mode, it will not hinder the normal sensing and reading of data, so the business has a greater probability of being able to proceed normally. However, if the mobile phone adopts the card reader working mode, it may not be easy to communicate normally with the near-field communication device as a simulated card when the near-field communication signal is in low-power mode. In order to solve this problem, one or more embodiments of this specification provide a flow chart of a control scheme for the low-power mode of the sensing object, see. Figure 3 .

[0076] Figure 3The process in includes the following steps:

[0077] S302: Detecting, by the signal sensing antenna, whether the near field communication signal of the sensing object enters a low power consumption mode.

[0078] Whether to enter the low power consumption mode can be detected by judging the strength of the sensing signal and the like.

[0079] S304: If yes, enable the near field communication device to operate in a card reader operation mode, and send a signal to the sensing object in the card reader operation mode, so that the near field communication signal of the sensing object exits the low power consumption mode.

[0080] After exiting the low power mode, the near field communication device can switch to the card emulation working mode so that the sensing object can be read as a card reader (card reader working mode is required).

[0081] pass Figure 3 The solution can make the near-field communication signal of the sensing object exit the low-power mode through the active intervention of the near-field communication device, so that the two parties can communicate more reliably. In this way, it can also avoid the target near-field communication antenna from excessively enhancing the signal strength in response to the low-power mode.

[0082] In one or more embodiments of the present specification, since the present application adopts multiple signal sensing antennas, combined with a scheme of targetedly optimizing a target near-field communication antenna for the current sensing object among multiple near-field communication antennas, it is possible to support serving multiple sensing objects simultaneously by performing parallel processing at the back end of multiple near-field communication antennas (relative software and hardware modifications can be performed).

[0083] Then, in this scenario, there may be multiple sensing objects currently approaching in step S102, and they may approach the near-field communication device from different directions respectively. Then, different target near-field communication antennas may be used to establish communication with multiple sensing objects accordingly, so as to perform business interactions simultaneously. From the user's perspective, multiple users hold their mobile phones and perform sensing interactions with the same near-field communication device from different directions at the same time, which can effectively improve service efficiency. Not only that, it can also implement some new business models and bring more convenience to users. For ease of understanding and intuitiveness, one or more embodiments of this specification provide a flow chart of a working scheme of a near-field communication cash register device, see Figure 4 .

[0084] Figure 4 The process in includes the following steps:

[0085] S402: Determine different target near field communication antennas for a plurality of sensing objects that are currently approaching the near field communication cashier device from different directions.

[0086] The multiple users to whom these multiple sensing objects belong can be acquaintances, such as friends, colleagues, relatives, etc., who can share the payment for the order by sensing each other in proximity. Specific scenarios include paying the bill after a meal or group ordering.

[0087] Of course, for multiple users who do not know each other, this solution can also be implemented in scenarios such as discount group purchases.

[0088] S404: establishing communications with the plurality of sensing objects correspondingly through different target near field communication antennas.

[0089] S406: Determine the amount to be paid for the current order.

[0090] Whether paying or group buying, the merchant only needs to generate an order to be paid for the person through the near-field communication cash register device. This greatly simplifies the merchant's operation, reduces the operating efficiency of the person, and is less likely to cause disputes.

[0091] S408: Split the amount to be paid, and disperse the split amount to multiple sensing objects through the established communication, so that each sensing object pays a portion of the received split amount to be paid.

[0092] Here, the splitting strategy can be determined differently according to the needs of specific scenarios. For example, in the scenario of discount group buying, differentiated splitting can be performed based on the portrait characteristics of different users (such as identity, status, consumption habits, friend relationships, etc.), so that different users may receive different amounts of the amount to be paid after splitting, and accordingly, different users may actually receive different discounts. For another example, in the scenario of friends gathering, the amount to be paid can be split equally.

[0093] It should be noted that Figure 4 In the example of , the association relationship between multiple users performing simultaneous sensing is more fully considered. In fact, even if multiple users interact through simultaneous sensing, it is of course possible to independently perform their own business in parallel.

[0094] The above describes the interactive processing scheme proposed in this application. Based on the same idea, this application also provides the main structure of a near field communication device that can be used to implement the above scheme, as well as several exemplary specific implementation structures based on the main structure, so as to facilitate a more intuitive understanding. Figures 5 to 10 Provide explanation.

[0095] Figure 5The structural diagram of a near field communication device provided for one or more embodiments of this specification presents the main structure of the device in a relatively abstract manner, but does not limit it to a specific module layout and connection relationship.

[0096] exist Figure 5 The near-field communication device includes multiple signal sensing antennas, multiple near-field communication antennas, and one or more control chips; at least two of the signal sensing antennas respectively sense a currently approaching sensing object; the control chip selects a near-field communication antenna close to the sensing object from the multiple near-field communication antennas as a target near-field communication antenna according to the difference in signal strengths respectively sensed by the at least two signal sensing antennas; the target near-field communication antenna establishes communication with the sensing object to perform business interaction.

[0097] These devices can be carried by a hard PCB or a flexible circuit board, or a combination of a hard PCB and a flexible circuit board connected together by connectors.

[0098] When laying out the antennas, in order to obtain a better sensing range and to make the signal sensing antenna and the near-field communication antenna more convenient to cooperate, multiple signal sensing antennas can be deployed in a dispersed manner around the near-field communication device and deployed on the outside. Correspondingly, multiple near-field communication antennas can be deployed in a dispersed manner around the near-field communication device and deployed on the inside. When laying out the control chip, these antennas can be controlled uniformly or distributedly using multiple sub-control chips. The specific connection structure is also diverse and can be selected according to actual needs. Intuitively, refer to Figure 6 to Figure 10 Five specific implementation structure examples in .

[0099] Figure 6 A schematic diagram of the specific structure of a first near field communication device in an application scenario provided by one or more embodiments of this specification.

[0100] exist Figure 6In the embodiment, the number of signal sensing antennas (8) is greater than the number of near-field communication antennas, and a control structure in which a control chip directly controls all antennas is adopted. When the mobile phone approaches the near-field communication device from direction 1, signal sensing antenna 1, signal sensing antenna 2, and signal sensing antenna 3 will synchronously sense the signal emitted by the mobile phone communication coil. Combined with the signal strength sensed by signal sensing antenna 1, signal sensing antenna 2, and signal sensing antenna 3, the control chip determines that the mobile phone near-field communication antenna is closer to the near-field communication antenna 1 of the near-field communication device based on the collected signal. The control chip forms a control logic to enhance the signal of near-field communication antenna 1 and at the same time turn off the control signals of near-field communication antenna 2, near-field communication antenna 3, and near-field communication antenna 4. In this case, near-field communication antenna 1 can establish communication with the mobile phone near-field communication antenna for data transmission.

[0101] By the same logic, when the mobile phone approaches the near-field communication device from direction 2, the near-field communication antenna 2 of the near-field communication device can establish communication with the near-field communication antenna of the mobile phone; when the mobile phone approaches the near-field communication device from direction 3, the near-field communication antenna 3 of the near-field communication device can establish communication with the near-field communication antenna of the mobile phone.

[0102] A socket may be reserved on the near field communication device for conveniently extending the signal sensing antenna or the near field communication antenna by plugging.

[0103] Figure 7 A schematic diagram of the specific structure of a second near field communication device in an application scenario provided by one or more embodiments of this specification.

[0104] Figure 7 Antenna layout and its working logic in Figure 6 They are roughly the same, with the main difference being the layout of the control chip. The signal sensing antenna is controlled by control chip 1, and the NFC antenna of the NFC device is controlled by control chip 2. Control chip 1 receives signals from different signal sensing antennas and makes judgments, then passes the judgment results to control chip 2. Control chip 2 controls which NFC antenna of the NFC device establishes communication with the NFC antenna of the mobile phone based on the results. This split control method reduces the working pressure of the control chip, and reduces the degree of coupling between the structures involved in different types of antennas, making it easier to expand.

[0105] Figure 8 A schematic diagram of the specific structure of a third near field communication device in an application scenario provided by one or more embodiments of this specification.

[0106] Figure 8The control chip adopts a unified direct control solution, and the antenna layout has been changed. The signal sensing antenna on the near-field communication device is deployed one-to-one with the near-field communication antenna, and the signal sensing antenna and its corresponding near-field communication antenna are deployed close to each other. This helps to more efficiently determine the target near-field communication antenna. For example, according to the difference in signal strength sensed by multiple signal sensing antennas, the approach direction of the sensing object to the near-field communication device is judged. According to the approach direction, the near-field communication antenna that is close to the sensing object is selected from the multiple near-field communication antennas deployed on the near-field communication device. Since the signal sensing antenna and its corresponding near-field communication antenna are very close to each other and their directions relative to the sensing object are basically the same, it is more convenient to use the near-field communication antenna corresponding to the signal sensing antenna with the strongest signal strength as the target near-field communication antenna.

[0107] exist Figure 8 In the embodiment, when the mobile phone approaches the near-field communication device from direction 1, the signal sensing antenna 2, the signal sensing antenna 3, and the signal sensing antenna 4 will synchronously sense the signal emitted by the mobile phone communication coil. The signal strengths sensed by the signal sensing antenna 2, the signal sensing antenna 3, and the signal sensing antenna 4 are different due to the difference in distance from the mobile phone near-field communication antenna. The control chip determines that the mobile phone near-field communication antenna is closer to the near-field communication antenna 3 of the near-field communication device based on the collected signal, and the control chip forms a control logic to enhance the signal of the near-field communication antenna 3 and turn off the control signals of the remaining near-field communication antennas. In this case, the near-field communication antenna 3 and the mobile phone near-field communication antenna Establish communication for data transmission; when the mobile phone approaches the near-field communication device from direction 2, the signal sensing antenna 1 and the signal sensing antenna 6 synchronously sense the signal emitted by the mobile phone communication coil. The signal sensing antenna 1 and the signal sensing antenna 6 sense different signal strengths due to the difference in distance from the mobile phone near-field communication antenna. The control chip determines that the mobile phone near-field communication antenna is closer to the near-field communication antenna 6 of the near-field communication device based on the collected signal. The control chip forms a control logic to enhance the signal of the near-field communication antenna 6 and at the same time turn off the control signals of the remaining near-field communication antennas.

[0109] Fig. 9A more fine-grained control chip sub-control layout is adopted in the system. The main control chip deployed on the near-field communication device controls multiple sub-control chips deployed on the near-field communication device. Each sub-control chip corresponds to a pair of signal sensing antennas and near-field communication antennas. The sub-control chip controls the corresponding pair of signal sensing antennas and near-field communication antennas. This makes it easier for each pair of antennas to cooperate with each other, which helps reduce the impact on other antennas.

[0110] exist Fig. 9 In the figure, when the mobile phone approaches the near-field communication device from direction 1, the signal sensing antenna 2, the signal sensing antenna 3, and the signal sensing antenna 4 will synchronously sense the signal emitted by the mobile phone communication coil, and the control chip 2, the control chip 3, and the control chip 4 will respectively transmit the signals sensed by the signal sensing antenna 2, the signal sensing antenna 3, and the signal sensing antenna 4 to the main control chip. Due to the difference in the distance from the mobile phone near-field communication antenna, there are differences in the signal strengths sensed by the sensing antenna 2, the signal sensing antenna 3, and the signal sensing antenna 4. The main control chip determines that the mobile phone near-field communication antenna is closer to the near-field communication antenna 3 of the near-field communication device based on the collected signal. The main control chip forms a control logic and transmits the control signal to the control chip 1, the control chip 2, the control chip 3, the control chip 4, the control chip 5, and the control chip 6 respectively, so as to enhance the signal of the near-field communication antenna 3 and turn off the control signals of the remaining near-field communication antennas. In this case, the near-field communication antenna 3 establishes communication with the mobile phone near-field communication antenna for data transmission.

[0111] When the mobile phone approaches the near-field communication device from direction 2, the signal sensing antenna 1 and the signal sensing antenna 6 synchronously sense the signal emitted by the mobile phone communication coil, and the control chip 1 and the control chip 6 respectively transmit the signals sensed by the signal sensing antenna 1 and the signal sensing antenna 6 to the main control chip. Because the signal strength sensed by the difference in distance from the mobile phone's near-field communication antenna is different, the main control chip determines that the mobile phone's near-field communication antenna is closer to the near-field communication antenna 6 of the near-field communication device based on the collected signal, and the control chip forms a control logic, and transmits the control signal to the control chip 1, the control chip 2, the control chip 3, the control chip 4, the control chip 5, and the control chip 6 respectively, to enhance the signal of the near-field communication antenna 6, and at the same time turn off the control signals of the remaining near-field communication antennas. In this case, the near-field communication antenna 6 establishes communication with the mobile phone's near-field communication antenna for data transmission.

[0113] Fig.10Another control chip layout scheme is adopted in which the main control chip directly controls the near-field communication antenna, and the sub-control chip controls the signal sensing antenna.

[0114] exist Fig. 9 In the figure, when the mobile phone approaches the near-field communication device from direction 1, the signal sensing antenna 2, the signal sensing antenna 3, and the signal sensing antenna 4 will synchronously sense the signal emitted by the mobile phone communication coil, and the control chip 2, the control chip 3, and the control chip 4 will respectively transmit the signals sensed by the signal sensing antenna 2, the signal sensing antenna 3, and the signal sensing antenna 4 to the main control chip. Due to the difference in distance from the mobile phone's near-field communication antenna, there are differences in the signal strengths sensed by the sensing antenna 2, the signal sensing antenna 3, and the signal sensing antenna 4. The main control chip determines that the mobile phone's near-field communication antenna is closer to the near-field communication antenna 3 of the near-field communication device based on the collected signal, and the main control chip forms a control logic to enhance the signal of the near-field communication antenna 3, and at the same time turn off the control signals of the remaining near-field communication antennas. In this case, the near-field communication antenna 3 establishes communication with the mobile phone's near-field communication antenna for data transmission.

[0115] When the mobile phone approaches the near-field communication device from direction 2, the signal sensing antenna 1 and the signal sensing antenna 6 synchronously sense the signal emitted by the mobile phone communication coil, and the control chip 1 and the control chip 6 respectively transmit the signals sensed by the signal sensing antenna 1 and the signal sensing antenna 6 to the main control chip. Because of the difference in distance from the mobile phone's near-field communication antenna, there is a difference in the signal strength sensed to the end. The main control chip determines that the mobile phone's near-field communication antenna is closer to the near-field communication antenna 6 of the near-field communication device based on the collected signal, and the control chip forms a control logic to enhance the signal of the near-field communication antenna 6 and at the same time turn off the control signals of the remaining near-field communication antennas. In this case, the near-field communication antenna 6 establishes communication with the mobile phone's near-field communication antenna for data transmission.

[0116] Of course, in addition to Figure 6 to Figure 10 In addition to the exemplary layouts in the figure, there are more specific layouts that can be selected and implemented as needed.

[0117] In one or more embodiments of the present specification, when multiple signal sensing antennas are arranged circumferentially, the near-field communication device may further have a matching screen in the circumference (for example, surrounding the circumference) to visually display the degree of sensing capability of the signal sensing antenna with graphics on the screen. For example, the more the graphic at the corresponding position protrudes outward, the higher the sensing capability is. Thus, the user can intuitively tend to move closer to the protruding part, which helps to improve the sensing success rate. Furthermore, the near-field communication device can dynamically adjust (for example, by increasing signal power, dynamically changing antenna shape, etc.) the sensing capabilities of the multiple signal sensing antennas according to the sensing conditions over a period of time. For different signal sensing antennas, the screen flashes with visually displayed graphic shapes (for example, corresponding graphic shapes can be designed with reference to corresponding business elements, or text prompts, etc.) to indicate different services. In this case, the user can refer to the graphic shape for the sensing object and, according to the business (as the target business) he wants to execute among a variety of optional businesses (for example, payment business, discount collection business, advertising business, content download business, etc.), move close to the graphic shape corresponding to the target business, that is, close to the signal sensing antenna corresponding to the graphic shape, so that the next business interaction will be the interaction with the target business, rather than other business interactions.

[0118] This visual graphic assistance solution makes the sensing capability more intuitive, and at the same time facilitates users to flexibly select services and helps to execute services efficiently.

[0159] In the 1990s, improvements to a technology could be clearly distinguished as hardware improvements (for example, improvements to the circuit structure of diodes, transistors, switches, etc.) or software improvements (improvements to the method flow). However, with the development of technology, many improvements to the method flow today can be regarded as direct improvements to the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that an improvement in a method flow cannot be implemented using a hardware entity module. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logical function is determined by the user's programming of the device. Designers can "integrate" a digital system on a PLD by programming it themselves, without having to ask a chip manufacturer to design and produce a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly implemented by "logic compiler" software, which is similar to the software compiler used when developing and writing programs, and the original code before compilation must also be written in a specific programming language, which is called hardware description language (HDL). There is not only one HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also know that it is only necessary to program the method flow slightly in the above-mentioned hardware description languages ​​and program it into the integrated circuit, and then it is easy to obtain the hardware circuit that implements the logic method flow.

[0160] The controller can be implemented in any appropriate manner, for example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing a computer-readable program code (such as software or firmware) that can be executed by the (micro)processor, a logic gate, a switch, an application-specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that in addition to implementing the controller in a purely computer-readable program code manner, the controller can be implemented in the form of a logic gate, a switch, an application-specific integrated circuit, a programmable logic controller, and an embedded microcontroller by logically programming the method steps. Therefore, this controller can be considered as a hardware component, and the devices included therein for implementing various functions can also be regarded as structures within the hardware component. Or even, the devices for implementing various functions can be regarded as both software modules for implementing the method and structures within the hardware component.
