Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The application provides a method, a device and a system for identifying the position of a chip card in a space and the chip card. The following detailed description is made with reference to the drawings of the embodiments provided in the present application, respectively.
A method for identifying a position of a chip card in a space according to a first embodiment of the present application is as follows:
an execution main body of the embodiment of the present application is an identification terminal, as shown in fig. 1, which shows a flowchart of a method for identifying a position of a chip card in a space provided by the embodiment of the present application, and is applied to a system including the chip card, the chip card is divided into at least 3 areas, each area is provided with an antenna, and operating frequencies of the antennas are different, including the following steps.
Step S101, identifying the working frequency of each antenna in the chip card.
The embodiment of the application is applied to a system for identifying the position of a chip card in a space, and comprises a chip card 1 and a device 2 for identifying the position of the chip card in the space, as shown in fig. 4. The device for identifying the position of the chip card in the space is arranged in the identification terminal, and the identification terminal identifies the chip card based on the device for identifying the position of the chip card in the space.
The chip card in the embodiment of the application is a non-contact chip card, generally, the non-contact chip card only works at one working frequency, in order to obtain a specific space position of the chip card, a proper card writing time is found, and then the chip card is accurately identified. In order to implement functions that operate simultaneously at more than one operating frequency, the chip card has an equal number of antennas to the number of operating frequencies. The antennas in the chip card do not share the same area, so that each antenna is used as a positioning point in the subsequent positioning, and the positioning points are not overlapped together. Namely, the chip card is divided into at least 3 areas, each area is provided with an antenna, the working frequencies of the antennas are different, and the chip card is provided with at least 3 antennas with different working frequencies.
In this step, the identification terminal can identify the operating frequency of each antenna in the chip card when the chip card is in operation with the identification terminal equipped with the receiving antenna. The receiving antenna in the identification terminal receives the different operating frequencies emitted by the antenna in the chip card. The range of the reception frequency in the identification terminal can be preset as required to match the range of the operating frequency emitted by the chip card, without being excessively limited here.
Preferably, one of the antennas in the chip card has an operating frequency of 13.56MHz ± 7 kHz.
It should be noted that the chip card needs to satisfy the condition that the operating frequency used by one antenna is 13.56MHz ± 7kHz which is widely used at present, so that the chip card has the downward compatibility capability of the existing identification terminal indirect payment function. The chip card is made compatible with existing chip card identification terminals on the market, for example pos machines, so that the existing identification terminals can read the basic information in our chip card. For example chip cards are used in payments, existing pos machines can still read the card number of a chip card in a contactless manner for a "flash" transaction. Wherein 13.56MHz ± 7kHz represents any one frequency in the range of 13.56MHz-7kHz to 13.56MHz +7kHz, 13.56MHz is the center frequency of the carrier, and 7kHz is the data bandwidth.
And S102, determining the spatial position of each antenna according to the working frequency of each antenna in the chip card.
In this step, the specific position of each antenna in space on the chip card is identified by the identification terminal based on smart antenna technology, also called beamforming, according to the operating frequency of each antenna in the chip card identified in step S101.
Preferably, the step of determining the spatial position of each antenna according to the operating frequency of each antenna in the chip card comprises: and determining the space coordinate of each antenna in a pre-established three-dimensional rectangular coordinate system according to the working frequency of each antenna in the chip card.
In this step, the points of each antenna at a specific position in space are represented in a pre-established three-dimensional rectangular coordinate system. The three-dimensional rectangular coordinate system is established by taking a receiving antenna in the identification terminal as an origin.
In a preferred embodiment, as shown in fig. 3, the chip card is divided into 4 fields, each of which is located at one of the four corners of the chip card, on each of which an antenna is arranged. The chip card is provided with 4 antennae and is arranged at 4 corners of the chip card, so that the position of the chip card is more convenient to locate.
Taking the chip card configured with 4 antennas as an example, as shown in fig. 3, a specific position of each antenna in space on the chip card is marked as one point in a three-dimensional rectangular coordinate system, and 4 points in the three-dimensional rectangular coordinate system are obtained by the 4 antennas. The intelligent antenna technology can obtain the included angle between the position of each antenna on the chip card and the three-dimensional rectangular coordinate system and the distance between each antenna on the chip card and the receiving antenna in the identification terminal. Since the antenna on a specific chip card operates at a specific operating frequency and is arranged at a specific position of the chip card (for example, the antenna operating at 13.56MHz ± 7kHz is embedded in all chip cards at a position closest to the exposed metal chip contacts), the receiving antenna in the identification terminal can distinguish which antenna on the chip card each point specifically represents, thereby determining the specific spatial position corresponding to each antenna in the chip card.
And step S103, determining the space position of the chip card according to the space position of each antenna.
In this step, the spatial position of the chip card is determined according to the specific spatial position corresponding to each antenna in the chip card determined in step S102. And determining the space position of the chip card according to the relative position of each point corresponding to each antenna in the three-dimensional rectangular coordinate system.
Taking the chip card configured with 4 antennas as an example, as shown in fig. 3, the specific position of each antenna on the chip card in space is marked as a specific point in a three-dimensional rectangular coordinate system, and since the antenna on the specific chip card operates at a specific operating frequency and is set at the specific position of the chip card, the spatial position of the chip card can be determined according to the relative positions of the 4 points corresponding to the 4 antennas in the three-dimensional rectangular coordinate system. The front side, the back side, the direction and the like of the chip card can be determined, and specific points corresponding to each antenna can be connected in a three-dimensional rectangular coordinate system to draw a virtual graph of the chip card and accurately describe the space position of the chip card, so that excessive limitation is not required.
The method is applied to a system comprising the chip card, the chip card is divided into at least 3 areas, each area is provided with one antenna, the working frequency of each antenna is different, the identification terminal determines the spatial position of each antenna according to the working frequency of each antenna in the chip card, and further the spatial position of the chip card can be determined according to the spatial position of each antenna. The situation that the card writing is failed finally because the card swinging speed of a card holder is too high and the position of the chip card is not suitable for card writing is avoided. And the relative distance between the chip card and the card reader is prevented from being measured by reusing a metal medium on the chip card, but the space position of the chip card can be determined, and the application range is wide.
