Detailed Description
The following presents a simplified summary of the invention in order to provide a basic understanding of the invention. It is not intended to identify key or critical elements of the invention or to delineate the scope of the invention.
For the purposes of brevity and explanation, the principles of the present 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 equally applicable to all types of UWB-based payment methods and UWB-based payment systems, and that these same principles may be implemented therein, and that any such variations do not depart from the true spirit and scope of the present patent application.

Electrical, mechanical, logical and structural changes may be made to these embodiments without departing from the spirit and scope of the present invention. Furthermore, while a feature of the invention may have been disclosed with respect to only one of several implementations/embodiments, such feature may be combined with one or more other features of the other implementations/embodiments, as may be desired and/or advantageous for any given or identifiable function. The following description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims and their equivalents.
Terms such as "comprising" and "including" mean that the technical solution of the present invention does not exclude the presence of other elements (modules) and steps than those directly and explicitly described in the description and claims.
In the invention, a plurality of UWB collecting devices are arranged at a merchant, UWB signals are broadcast to a certain range around the UWB collecting devices, and when a user holding UWB mobile payment devices approaches the UWB collecting devices of the merchant, whether to establish communication connection and whether to push a payment bill from the UWB collecting devices to the UWB mobile payment devices is judged according to the position relation between the UWB collecting devices and the UWB mobile payment devices.
In the present invention, a payment area, a marking area, and a silent area are preset. Fig. 1 is a schematic diagram of one example of a payment zone, a marking zone, and a quiet zone of the present invention. As shown in fig. 1, a plurality of UWB collecting devices are disposed between the payment channel entrance and the payment channel exit, and when a user holding the UWB mobile payment device approaches the UWB collecting device, a positional relationship between the UWB collecting device and the UWB mobile payment device is formed, which is represented in fig. 1 as a distance R between the UWB collecting device and the UWB mobile payment device and an angle θ between the UWB collecting device and the UWB mobile payment device.
In fig. 1, a payment area and a tag area are sequentially divided according to a communication radius and an area where the tag areas of two UWB collection devices overlap each other is set as a silent area. For example, as one example, the radius of the mark area is l b The radius of the payment area is l z ，l z ＜l b 。
Specifically, regarding the tag area, when a user enters the signal range of the UWB collecting device, the UWB collecting device establishes connection with the UWB mobile payment device, the angle θ and the distance R between the UWB mobile payment device and the UWB collecting device are determined through the UWB positioning technology, the UWB collecting device determines whether the mobile payment UWB device is located in the tag area of the UWB collecting device according to the angle θ and the distance R, and in the case of the tag area, the UWB collecting device obtains the unique UWB identification of the UWB mobile payment device of the user and waits for pushing a payment bill.
With respect to the payment zone, a payment order pushed by a merchant's UWB payment receiving device may be received after the user's UWB mobile payment device enters the payment zone. Here, as a more preferable mode, the verification of the user side can be further increased, namely, the order receivable range (including the distance and the angle) for receiving the payment order of the UWB payment collecting device can be preset on the user side, the payment order is pushed from the UWB payment collecting device to the UWB mobile payment device only if the position relationship between the UWB mobile payment device and the UWB mobile payment device accords with the preset order receivable range, and thus the number of wrongly pushed orders can be reduced and the payment orders of other users are ensured not to be pushed through the bidirectional verification of the merchant side and the verification of the user side in the preferable mode.
With respect to the silence area, in order to avoid binding of multiple UWB payees by the same mobile device, the communication connection between the merchant's UWB payees and the user's UWB mobile payment device is broken when the user's UWB mobile payment device enters the silence area.
Fig. 2 is a flow chart of a UWB-based payment method according to an embodiment of the present invention.

target determination step S400: in the step S300, if it is determined that the UWB mobile payment device is located in the tag region and not located in the silence region, determining that one UWB mobile payment device is an order pushing target;
First verification step S500: when the UWB mobile payment device is further approaching to the UWB collection device, the UWB collection device acquires second position information of the UWB mobile payment device relative to the UWB collection device and verifies whether the mobile payment UWB device is located in a payment area based on the second position information; and
order pushing step S600: in the case where it is verified in the first verification step S500 that the UWB mobile payment device is located in the payment area, the UWB payment receiving device pushes a payment order to the UWB mobile payment device as an order push target.
Further, preferably, between the first verification step S500 and the pushing step S600, there is further included (not shown):
a position information transmitting step of transmitting the second position information to the UWB mobile payment device as the order push target, in the case where it is determined in the first verification step S500 that the UWB mobile payment device is located in the payment area; and
and a second verification step of obtaining a verification result used for indicating that the UWB mobile payment device can receive the payment order from the UWB mobile payment device, wherein the verification result is used for indicating that the second position information accords with an order receivable range preset by the UWB mobile payment device.
