It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application.

[0046] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0047] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0048] This application provides an NFC card inspection system, such as Figure 1 As shown, the NFC card detection system includes: a control module 11, a proximity detection module 12 and an NFC detection module 13, wherein:

[0049] The first end of the control module is connected to the proximity detection module 12, and the second end of the control module 11 is connected to the NFC detection module 13;

[0050] The proximity detection module 12 is used to send a proximity notification to the control module 11 when detecting that an object is approaching;

[0051] The control module 11 is used to control the NFC detection module 13 to be in a working state and send a card detection instruction to the NFC detection module 13 when receiving the proximity notification;

[0052] The NFC detection module 13 is configured to detect whether the object is an NFC device when in working state and receiving a card detection instruction.

[0053] In one example, the control module 11 can be exemplarily an MCU. On this basis, the first end of the control module 11 and the second end of the control module 11 can be exemplarily an SPI interface, a UART interface or an IIC interface on the MCU.

[0054] In this embodiment, the proximity detection module 12 is used to detect whether an object is approaching the proximity detection module 12. The object can be an NFC device or a non-NFC device, with a non-NFC device being exemplified by a human hand. Furthermore, the NFC detection module 13 and the proximity detection module 12 are both modules in the NFC card inspection system, and the NFC detection module 13 and the proximity detection module 12 are physically close. Therefore, the proximity detection module 12 detects whether an object is approaching the proximity detection module 12, that is, detects whether an object is approaching the NFC detection module 13.

[0055] Furthermore, when the proximity detection module 12 detects that an object is approaching the proximity detection module 12, the proximity notification is sent to the control module 11. In one example, the proximity notification may be specifically an interrupt signal.

[0056] Upon receiving the proximity notification from the proximity detection module 12, the control module 11 determines that an object is approaching the NFC detection module 13. At this point, the control module 11 controls the NFC detection module 13 to be in an active state and simultaneously sends a card detection instruction to the NFC detection module 13. It should be noted that the initial state of the NFC detection module 13 is an inactive state, i.e., a low-power mode.

[0057] In one embodiment, the control module 11 is initially in a non-operating state, i.e., a low-power mode. Upon receiving a proximity notification, the control module 11 is awakened and enters an operating state. Specifically, upon receiving a proximity notification, the control module 11 is further configured to enter an operating state, control the NFC detection module 13 to operate, and send a card detection instruction to the NFC detection module 13. Thus, the control module 11 is only in an operating state when an object approaches. This avoids the problem of high power consumption caused by the control module 11 remaining in an operating state when no object approaches the NFC detection device.

[0058] In an example, the control module 11 may control the NFC detection module 13 to be in the working state by sending a wake-up instruction to the NFC detection module 13 .

[0059] When the NFC detection module 13 is in working state and receives the card detection instruction, it enters the POLLING mode to detect whether the object close to the NFC detection module 13 is an NFC device. Based on this, the NFC card detection is completed.

[0060] In one example, using the NFC card detection device provided herein as a car key system, if the NFC detection module 13 detects that the object is an NFC device, it will perform NFC data exchange with the NFC device. If the NFC detection module 13 successfully authenticates the NFC device based on the data exchange result, it will unlock the car door. Conversely, if the NFC device authentication fails, the car door remains locked.

[0061] Based on the above, the present application provides an NFC card inspection system, in which the proximity detection module 12 first detects whether an object is approaching. When an object approaches, the control module 11 controls the NFC detection module 13 to be in an operating state. In this way, the problem of high power consumption caused by the NFC detection module 13 being in an operating state when no object is approaching the NFC detection device is avoided, that is, the power consumption of the NFC card inspection system is effectively reduced. In the case where the NFC card inspection system is a car key system, the present application provides a low-power car key system.

[0062] Correspondingly, if the proximity detection module 12 does not detect an approaching object, it will not send a proximity notification to the control module 11. Consequently, the control module 11 will not receive the proximity notification, nor will it control the NFC detection module 13 to operate or send a card detection instruction to the NFC detection module 13. At this point, the NFC detection module 13 is in its initial state, i.e., low-power mode.

[0063] The present application provides an NFC card detection system, comprising: a control module, a proximity detection module, and an NFC detection module, wherein: a first end of the control module is connected to the proximity detection module, and a second end of the control module is connected to the NFC detection module; the proximity detection module is used to send a proximity notification to the control module when detecting that an object is approaching; the control module is used to control the NFC detection module to be in an operating state and send a card detection instruction to the NFC detection module when receiving the proximity notification; the NFC detection module is used to detect whether the object is an NFC device when it is in an operating state and receives a card detection instruction. The NFC card detection system first detects whether there is an object approaching through the proximity detection module. Only when an object is approaching does the control module control the NFC detection module to be in an operating state. In this way, the problem of high power consumption caused by the NFC detection module being in an operating state when no object is approaching the NFC detection device is avoided, that is, the power consumption of the NFC card detection system is effectively reduced. In the case where the NFC card detection system is a car key system, the present application provides a low-power car key system.

[0064] In one embodiment of the present application, Figure 1 As shown, the NFC card detection system provided in this application further includes a power module 15 , which is used to supply power to the control module 11 , the NFC detection module 13 and the proximity detection module 12 .

[0065] Furthermore, in one embodiment, the power detection module is connected to the control module 11 , the NFC detection module 13 , and the proximity detection module 12 , respectively.

[0066] In another embodiment, Figure 1 As shown, the power module 15 is connected to the control module 11 to provide power to the control module 11. The control module 11 transfers the power provided by the power module 15 to the NFC detection module 13 and the proximity detection module 12 connected thereto.

[0067] In one embodiment of the present application, Figure 2 As shown, the NFC card inspection system provided by the present application further includes a switch module 14, wherein:

[0068] The first end of the control module 11 is connected to the proximity detection module 12 through the switch module 14, and the third end of the control module 11 is connected to the control end of the switch module 14;

[0069] The NFC detection module 13 is further configured to send a confirmation notification that the object is an NFC device to the control module 11 when detecting that the object is an NFC device;

[0070] The control module 11 is further configured to control the switch module 14 to be disconnected when a positive notification is received.

[0071] In this embodiment, when the NFC detection module 13 detects that the object approaching the NFC detection module 13 is an NFC device, it sends a positive notification to the control module 11. The positive notification is used to indicate that the object approaching the NFC detection module 13 is an NFC device.

[0072] Upon receiving this positive notification, the control module 11 determines that the object approaching the NFC detection module 13 is an NFC device. At this point, the proximity detection module 12 is no longer required to detect the presence of an object. Based on this, the control module 11 controls the switch module 14 to disconnect, thereby disabling the proximity detection module 12. This prevents the control module 11 from receiving data sent by the proximity detection module 12, further reducing the power consumption of the control module 11 and, consequently, the power consumption of the NFC card detection system provided herein.

[0073] Correspondingly, if the NFC detection module 13 detects that the object is not an NFC device, it sends a negative notification to the control module 11 indicating that the object is not an NFC device. The control module 11 is also configured to control the switch module 14 to conduct upon receiving the negative notification. Based on this, the control module 11 continues to receive data sent by the detection module.

[0074] In one embodiment of the present application, Figure 2 As shown, the proximity detection module 12 is a capacitance measurement module 121 .

[0075] In this embodiment, the proximity detection module 12 is implemented by a capacitance measurement module 121. When an object approaches, the capacitance value detected by the capacitance measurement module 121 changes. Therefore, the proximity of an object can be detected based on the capacitance value detected by the capacitance measurement module 121. Based on this, the present application provides a specific implementation of the proximity detection module 12.

[0076] In addition, the sensing distance of the capacitance measurement module 121 is longer than that of NFC. On this basis, the NFC card detection system provided by the present application can respond more quickly to whether an object is approaching.

[0077] Based on the previous embodiment, Figure 3 As shown, the capacitance measurement module 121 includes: an oscillator 1211, an excitation electrode 1212, a sensing electrode 1213, a rectifier electrode and an analog-to-digital converter 1215, wherein:

[0078] The excitation electrode 1212 and the sensing electrode 1213 are arranged opposite to each other;

[0079] The oscillator 1211 is connected to the excitation electrode 1212;

[0080] A first end of the rectifier 1214 is connected to the sensing electrode 1213 , and a second end of the rectifier 1214 is connected to a first end of the analog-to-digital converter 1215 ;

[0081] A second terminal of the analog-to-digital converter 1215 is connected to a first terminal of the control module 11 .

[0082] In this embodiment, the excitation electrode 1212 and the sensing electrode 1213 are arranged opposite each other to form a capacitor. The oscillator 1211 is configured to output an oscillating signal of a certain frequency to the excitation electrode 1212. Upon receiving the oscillating signal output by the oscillator 1211, the excitation electrode 1212 generates an electric field of a fixed frequency. The electric field of the excitation electrode 1212 generates a certain amount of charge on the sensing electrode 1213. When an object approaches the capacitance measurement module 121, the amount of charge on the sensing electrode 1213 changes, and the amount of charge on the sensing electrode 1213 represents the capacitance formed by the sensing electrode 1213 and the excitation electrode 1212. Furthermore, the AC voltage signal generated by the charge on the sensing electrode 1213 changes, wherein the voltage value of the AC voltage signal is linearly proportional to the capacitance formed by the sensing electrode 1213 and the excitation electrode 1212. The rectifier 1214 rectifies the AC voltage signal output by the sensing electrode 1213 to output a DC voltage signal to the analog-to-digital converter 1215. The analog-to-digital converter 1215 performs analog-to-digital conversion on the DC voltage signal to obtain a voltage value of the DC voltage signal. Furthermore, the data module compares the obtained voltage value with the change in the preset voltage value. If the change is greater than a preset threshold, a proximity notification, such as an interrupt signal, is sent to the control module 11. The preset voltage value is the voltage value obtained by the analog-to-digital converter 1215 when no object is near the capacitance measurement module 121. The preset threshold is the maximum deviation between the voltage value obtained by the analog-to-digital converter 1215 and the preset voltage value when an object is near the capacitance measurement module 121. This maximum deviation can be determined based on experience or experimentation.

[0083] The present application provides a specific structure of a capacitance measurement module 121 , which is simple and easy to implement.

[0084] Based on the above embodiments, in one embodiment of the present application, Figure 4 As shown, the rectifier 1214 is a synchronous rectifier 12141 , and the oscillator 1211 is connected to a third terminal of the rectifier 1214 .

[0085] In this embodiment, rectifier 1214 is a synchronous rectifier 12141, and oscillator 1211 is connected to the excitation electrode 1212 and also to the third terminal of rectifier 1214. Based on this, rectifier 1214 can adjust the phase of the oscillation signal output by oscillator 1211 and the AC voltage signal output by sensing electrode 1213 to be the same. As a result, the conversion efficiency of the DC voltage signal converted by rectifier 1214 is improved.

[0086] In one embodiment of the present application, Figure 2 and Figure 5 As shown, the NFC card detection system includes an antenna board 16, and the NFC detection module 13 includes at least an NFC antenna 132, wherein:

[0087] The NFC antenna 132 and the sensing electrode 1213 are disposed on the antenna board 16 .

[0088] In this embodiment, the antenna board 16 is used to support the NFC antenna 132 and the sensing electrodes 1213. As a result, the physical distance between the sensing electrodes 1213 is close. The detection of whether an object is near the capacitance measurement module 121 by the capacitance measurement module 121 can accurately indicate whether an object is near the NFC detection module 13.

[0089] In one embodiment of the present application, Figure 2 and Figure 5 As shown, the NFC card detection system further includes a PCB board 17, and the NFC detection module 13 further includes an NFC chip 131, wherein:

[0090] The control module 11 , the NFC chip 131 , the oscillator 1211 , the excitation electrode 1212 , the rectifier 1214 and the analog-to-digital converter 1215 are disposed on the PCB board 17 .

[0091] In this embodiment, the NFC chip 131 is used to respond to instructions sent by the control module 11, such as a wake-up instruction, a card check instruction, etc. The NFC chip 131 is also used to receive signals received by the NFC antenna 132 and send a positive notification to the control module 11.

[0092] The NFC card inspection system further includes a PCB board 17 , which is used to carry the control module 11 , the NFC chip 131 , the oscillator 1211 , the excitation electrode 1212 , the rectifier 1214 and the analog-to-digital converter 1215 .

[0093] In this embodiment, a deployment method for the control module 11, NFC chip 131, oscillator 1211, excitation electrode 1212, rectifier 1214, and analog-to-digital converter 1215 in an NFC card inspection system is provided. This deployment method is compact and reasonable.

[0096] In one example, the NFC antenna 132 is disposed around the sensing electrode 1213 and is also arranged at the edge of the antenna board 16 .
