Description

Technical Field

[0001] The present invention relates to the technical field of smart cards, and in particular, to a method and system for controlling the reading and writing of a luminous smart card. Background Art

[0002] Ordinary luminous smart cards usually obtain electrical energy by using the induction coil in the card, and then drive the circuits and light-emitting devices in the card to emit light, which can realize basic reading and writing prompt functions. The light-emitting function of a smart card is different from the information stored in the smart card itself, and the reading circuit is usually separate. However, both of them need to interact with the card reader to generate data writing, so a conflict occurs in the reading and light-emitting functions of the smart card. There is no solution to this conflict in the prior art, resulting in the inability to simultaneously implement the reading and writing and the sequential light-emitting control of the smart card. At the same time, the existing luminous smart cards can only achieve one form of light emission, and the reusability is poor. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] The terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above accompanying drawings are intended to cover non-exclusive inclusion. The terms "first" and "second" are only used for naming purposes to distinguish, and do not represent the size or order of numbers. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include unlisted steps or units, or may optionally further include other steps or units inherent to these processes, methods, products or devices.

[0025] It should be noted that, for the convenience of understanding the roles played by different devices in the luminous smart card during the read-write control process of this application, the timing luminous control circuit of the smart card in this application will be introduced first. This circuit may at least include a controller, a timing memory storage unit, an encoder, load modulation, an antenna circuit, a modulation / demodulation decoder, a luminous unit drive circuit, a power supply circuit, and a clock. The connection relationships or connection structures of different devices in the circuit are as Figure 1 shown.

[0026] Among them, the antenna circuit: is used to obtain radio frequency energy.

[0027] The power supply circuit: after rectifying and stabilizing the radio frequency energy obtained by the antenna circuit, provides a DC working voltage for other circuits.

[0028] The clock: after the frequency of the carrier signal obtained by the radio circuit is divided, the divided signal is used as the clock signal of this circuit.

[0029] The modulation / demodulation circuit: modulates and demodulates the data transmitted by the read / write device, that is, the smart card reader in this application, through a wireless signal.

[0030] The detection and identification unit: judges and detects the instructions sent by the read / write device and analyzes the instructions.

[0031] Controller: In the write mode, it writes the data transmitted from the read / write device into the timing storage memory unit; in the light-emitting mode, it controls the light-emitting unit driving circuit to drive the light source to emit light according to the timing stored in the timing storage memory unit; in the read mode, it sends the light-emitting timing stored in the timing storage memory unit to the read / write device through the encoder and the load modulation unit as the content data of the timing storage memory unit.

[0032] Timing storage memory unit: It has an erasable and writable function for users to store the light-emitting timing.

[0033] Light-emitting unit driving circuit: It is used to drive the light source on the light-emitting smart card to emit light according to the timing stored in the timing storage memory unit.

[0034] Encoder: It encodes the data sent to the read / write device.

[0035] Load modulation: It realizes resistance load modulation and ASK modulation based on the carrier amplitude.

[0036] In the first embodiment of the present application, a method for controlling the reading and writing of a light-emitting smart card is provided, and the specific process is as Figure 2 shown, mainly including the following steps:

[0037] S101, judge the radio frequency signal sent by the smart card reader / writer to determine the working mode of the light-emitting smart card.

[0038] It can be understood that the system needs to perform some basic processing on the radio frequency signal sent by the smart card reader / writer through the timing light-emitting control circuit in the smart card before it can judge the working mode of the signal pronunciation. Among them, the working mode of the light-emitting smart card can include the read mode, the write mode, and the light-emitting mode. It should be noted that the above three working modes are all centered on the smart card reader / writer. The read mode is the mode when the reader / writer reads the card, the write mode is the mode when the reader / writer writes the card, and the light-emitting mode is the mode when the reader / writer drives the smart card to emit light.

[0039] In specific implementation, in the energy transmission timing, the power supply circuit in the timing light-emitting control circuit can rectify and regulate the radio frequency energy obtained by the antenna circuit to provide a DC working voltage for other circuits. And the clock can divide the frequency of the carrier signal obtained by the wireless circuit and use the divided signal as the clock signal of the timing light-emitting control circuit.

[0040] Furthermore, the modulation and demodulation decoder in the timing light-emitting control circuit can decode the instructions / data sent by the smart card reader / writer. Furthermore, the detection and recognition unit can be used to recognize the working mode indicated by the modulated and decoded instructions / data.

[0041] In a preferred implementation, the system may use a detection and recognition unit to recognize the radio frequency information signal frequency, special signal identification code, scanning area, or signal strength in the modulated and decoded instructions / data, and then determine the working mode according to different recognition results.

[0042] For example: When recognizing the working mode according to the radio frequency signal frequency, the antenna circuit can recognize the frequency of the carrier wave and then recognize the working mode. It is set that there are three frequencies: f 1 、f 2 、f 3 ,f 1 corresponds to the read mode, f 2 corresponds to the write mode, f 3 corresponds to the light-emitting mode. When recognizing the working mode according to the special signal identification code, it can be recognized according to the identification of specific bits of the modulation and demodulation decoder. It is set that there are three identification words: I 1 、I 2 、I 3 ,I 1 corresponds to the read mode, I 2 corresponds to the write mode, I 3 corresponds to the light-emitting mode. When recognizing the working mode according to the signal strength, the antenna circuit can recognize the signal strength of the carrier wave. It is set that there are three intensities: df 1 、df 2 、df 3 ,df 1 corresponds to the read mode, df 2 corresponds to the write mode, df 3 corresponds to the light-emitting mode.

[0043] S102, based on the timing light control circuit, control the light-emitting smart card to work according to the working mode.

[0044] It should be noted that after the detection and recognition unit recognizes the working mode, it can send the recognition result to the controller, so that it controls the timing light control circuit to control the smart card to work according to the corresponding working mode, for example, reading, writing, or emitting light.

[0045] In specific implementation, the control process of the system for different working modes is as follows:

[0046] In the read light-emitting logic working mode: The system can control the controller to read the timing data from the timing memory storage unit in the card, then perform encoding, decoding, and modulation on the timing data based on the encoder and load modulation, and finally transmit the encoded, decoded, and modulated timing data on the antenna radio frequency signal to the smart card reader / writer based on the antenna circuit.

[0047] In the write light-emitting logic working mode: The system uses the controller to store the data transmitted by the modulation and demodulation decoder into the timing storage memory unit.

[0048] In the light-emitting working mode: The system can use a controller to read the timing data in the timing storage memory unit and import it into the light-emitting unit drive circuit to drive the light source in the smart card to emit light according to the stored timing.

[0049] In an alternative embodiment, the system can also perform mode verification on different working modes according to a verification method matching the working mode.

[0050] It should be noted that through mode verification, the system can prompt the user whether the smart card is working properly in the corresponding mode. The specific verification methods can be:

[0051] For the read light-emitting logic working mode, the read logic can be displayed once in the light-emitting mode using the next time slot.

[0052] For the write light-emitting logic working mode, the written data can be verified, and then the written logic can be displayed once in the light-emitting mode using the next time slot.

[0053] For the light-emitting working mode, an end identifier can be displayed after the light emission ends (the light source is fully lit and then fully extinguished repeatedly k times, where k is a positive integer).

[0054] In the embodiments of the present invention, by processing the radio frequency signal sent by the smart card reader / writer to determine the working mode of the smart card, and then realizing the working control in different working modes based on different control devices in the timing control circuit in the card, the logical control of the read, write, and light-emitting working modes of multiple light sources in the smart card is realized. At the same time, the multiplexing of the light-emitting smart card is increased through the light-emitting logic storage device in the card.

[0055] In the second embodiment of the present application, a detailed implementation process of the light-emitting smart card read / write control is provided:

[0056] In this embodiment, the system can first define the light-emitting timing coding format of the light-emitting smart card according to a single frame or multiple frames.

[0057] In specific implementation, when defining the light-emitting timing coding format, it can be divided into two methods for single frame and multiple frames.

[0058] For a single frame: Under the single-frame coding format, data coding based on light intensity, color, and flash frequency is performed on the light sources in the smart card. For example, at a certain moment t, the light-emitting mode of the light source is represented by binary data. When it is a single frame, it is further divided into single-source coding for a single smart card light source and multi-source coding for multiple light sources.

[0059] 1) Single smart card light source

[0060] A single light source s can produce different light brightness, colors, and stroboscopies for encoding.

[0061] Light intensity: Divide the luminous intensity Nt of the light source s into l levels, where l is a power of 2. Denote them as Nt 1 , Nt 2 , …, Nt l representing the light intensities at each level respectively. The difference in light intensity between each level is Δd, i.e., Nt i - Nt i-1 = Δd. Then Nt 1 , Nt 2 , …, Nt l can represent consecutive binary numbers from 0 to .

[0062] Color: The light source s can emit m kinds of colored lights, where m is a power of 2. Denote them as C 1 , C 2 , …, C m representing various light colors respectively, with a sufficient color discrimination. Then C 1 , C 2 , …, C m can represent consecutive binary numbers from 0 to .

[0063] Stroboscopy: The light source s can flash at n frequencies, where n is a power of 2. Denote them as F 1 , F 2 , …, F n representing various flashing frequencies respectively. F 1 , F 2 , …, F n can represent consecutive binary numbers from 0 to .

[0064] At a certain moment t, the brightness, color, and stroboscopy of the light source s constitute a -bit binary number representation (the combination order can be reversed).

[0065] For example: l = 4, m = 2, n = 8. When s emits light at a certain moment with light intensity 3, color 1, and stroboscopy 5,

[0066] then the three respectively correspond to the binary numbers: 11 (light intensity component), 1 (color component), 101 (stroboscopy component);

[0067] Therefore, it constitutes the binary number: 111101.

[0068] Thus, the data encoding of a single light source is completed.

[0069] 2) Multi - light - source data encoding

[0070] There are multiple light sources on the luminous smart card, forming a light source set S, S = *s 1 ,s 2 ,…+ Taking the smart card reference position p as the starting point, the light source data is sorted or combined according to the distance between the light source and point p.

[0071] According to the sorting, the light sources are organized into a sequence [s 1 ,s 2 ,…], read the coded data of each light source, and then the data content at time t on the entire smart card is formed, which is a ( A binary number of bits, where |S| is the modulus value of the set S, is the encoded data of the image frame corresponding to time t.

[0072] For multiple frames: single frames can be aligned and combined based on the synchronization signal alignment method to obtain data encoding in a multi-frame encoding format, wherein the synchronization signal alignment method can include active synchronization and passive synchronization.

[0073] 1) Active synchronization

[0074] Active synchronization is designed to set a specific light source on the luminous smart card 0 , this particular light source is different from other light sources. Then, synchronization can be performed by the following two methods.

[0075] Method 1:

[0076] The light source 0 Special color C 0 , brightness Nt 0 , frequency F 0 One or a combination of:

[0077]

[0078]

[0079]

[0080] Method 2:

[0081] The light source 0 At the specified position of the smart card, the position coordinates are (x o ,y 0 ).

[0082] where s 0 A different lighting mode is adopted in each cycle (frame) time.

[0083] Mode 1 is special color C 0 , brightness Nt 0 , frequency F0 One or a combination of them is lit, and in Mode 2, it is a non - special color C 0 and brightness Nt 0 and frequency F 0 One or a combination of them is lit. The two modes appear alternately, and the lighting duration for each appearance is T.

[0084] 2) Passive synchronization

[0085] The passive method is to make a judgment by judging the light source data on the smart card.

[0086] The judgment condition is: record the light - emitting states of current light sources, including: light brightness, color, and stroboscopic effect, with a duration of τ, and τ>T. Therefore, within the time τ, there must be a light source whose light - emitting state changes. Then, the time point of detecting the state change is used as the synchronization starting point, that is, the time when the frame starts.

[0087] Using the above synchronization, the light - emitting data is separated into multiple frames, as Figure 3 shown.

[0088] Furthermore, the system can control the smart card to work in the corresponding working mode according to the above data encoding.

[0089] In the third embodiment of this application, the implementation structure or optional implementation methods of the detection and recognition unit, clock, controller, and extended IO in the timing light - emitting control circuit are introduced:

[0090] The detection and recognition unit is as Figure 4 shown. This detection and recognition unit is composed of Lab, logic gates, and amplifier connection lines. Among them, Lab is a specific register unit, and the data is controlled by the smart card chip. Users can program it to preset different control logics. The serial instructions sent by the read / write device are subjected to serial - to - parallel conversion through a four - bit D flip - flop, sent to the data transmission gate for comparison with the preset data instructions in Lab, for judgment detection, instruction analysis, and then enter the MCU on the smart card for further processing.

[0091] The clock is as Figure 5 shown. Among them, the frequency of the carrier signal obtained by the on - card LC resonance circuit is frequency - divided and then enters the phase - locked loop circuit to obtain a stable clock signal, and this signal is used as the working clock for the detection and recognition unit and the smart card chip.

[0092] The controller is as Figure 6As shown, it is composed of a contactless CPU card chip, and the contactless CPU card chip can have the following characteristics: compatible with contactless card chips, supporting a data transmission rate of 106 Kbps, low-voltage detection reset, high / low-frequency detection reset, and a typical transaction process less than 350 ms, etc. The security mechanism of the contactless CPU card chip can be an anti-power analysis module and a high / low-frequency detection reset module, and the chip automatically resets when the operating frequency exceeds the detection range.

[0093] Expanded IO such as Figure 7 As shown, limited by the number of IO pins of the smart card cpu, it is impossible to directly control the states of multiple LEDs. Therefore, it is necessary to expand the cpu IO. The figure shows a circuit for converting a three-bit binary number to a decimal number. The largest three-bit binary number can represent the decimal number "8", thus completing the expansion of three-wire to eight-wire IO.
