detailed description

In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only the technical solutions of the present invention. Some, but not all, embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

The NFC (Near Field Communication, near-field communication) mentioned in the embodiment of the present invention, also known as short-distance wireless communication, is a short-distance high-frequency wireless communication technology that allows non-contact point-to-point data transmission between electronic devices , Exchange data within twenty centimeters.

Please refer to FIG. 1 . FIG. 1 is a functional block diagram of an NFC-based anti-theft monitoring system provided by an embodiment of the present invention. The system includes a first terminal 10 and a second terminal 20 with an NFC communication function. The first terminal 10 and the second terminal 20 are used in combination to achieve the effect of anti-theft monitoring.

Specifically, please refer to FIG. 2 . FIG. 2 is a schematic structural diagram of an NFC-based anti-theft monitoring system provided by an embodiment of the present invention. Wherein, the first terminal 10 is an intelligent terminal display stand, and the second terminal 20 is an intelligent terminal.

Specifically, the first terminal 10 includes: a first NFC communication connection module 11, a first alarm module 12, a timer 13, a threshold setting module 14, a memory 15, and a wireless charging module 17; the second terminal 20 includes: a second NFC communication The module 21 and the battery 22 are connected.

Wherein, the first NFC communication connection module 11 is used to establish an NFC communication connection with the second terminal 20, specifically, the first terminal 10 and the second terminal 20 are established through the first NFC communication connection module 11 and the second NFC communication connection module 21 NFC communication connection realizes data and information exchange between two terminals.

Specifically, the first NFC communication connection module 11 is also used to detect in real time whether the NFC communication connection established by the two terminals is disconnected; if so, send a link establishment signal for establishing NFC communication to the second terminal 20; otherwise, send a signal to the wireless charging module 17 Sending a wireless charging notification signal. When the wireless charging module 17 receives the wireless charging notification signal, it immediately turns on the wireless charging function, and starts wireless charging for the battery 22 of the second terminal 20 .

In this embodiment, because the connection distance of NFC communication is relatively short, that is, the distance between the first terminal 10 and the second terminal 20 must be within the short distance limited by NFC communication to establish an NFC communication connection, which exceeds the limit of NFC communication. The short distance, the established NFC communication connection is disconnected. The short distance limited by NFC communication is generally ten centimeters or twenty centimeters.

In order to keep the power of the second terminal 20 sufficient, when the second terminal 20 is placed on the first terminal 10 for display, the distance between the two terminals is relatively short to meet the link establishment requirements of the NFC communication connection, the first terminal 10 and the second terminal 10 The terminal 20 can normally establish an NFC communication connection. At this time, the wireless charging module 17 is notified to turn on the wireless charging function and start to wirelessly charge the battery 22 of the second terminal 20; when the displayed electronic product, that is, the second terminal 20 is moved away When the first terminal 10, that is, after the distance between the two terminals exceeds the short distance limited by NFC communication, the established NFC communication connection is disconnected, and the first NFC communication connection module 11 immediately sends a signal to the wireless charging module 17 to stop charging. notification signal, the wireless charging module 17 immediately turns off the wireless charging function, and stops wireless charging for the battery 22 of the second terminal 20 . In this way, the wireless charging module 17 will not work all the time, and only when the second terminal 20 is not in use and placed on the first terminal 10, it will wirelessly charge the second terminal 20, which not only reduces the power consumption of the first terminal 10, At the same time, it can also ensure that the power of the second terminal 20 is sufficient.

Specifically, when the first NFC communication connection module 11 detects that the NFC communication connection is disconnected, it sends a link establishment signal for establishing NFC communication to the second terminal 20; The return signal of the chain signal; if so, re-establish the NFC communication connection with the second terminal 20; otherwise, notify the timer 13 to start timing, and obtain the disconnection time of the NFC communication connection in real time.

More specifically, when the first NFC communication connection module 11 detects that the NFC communication connection is disconnected, it sends a notification signal to start timing to the timer 13, and the timer 13 starts counting after receiving the notification signal to start counting. The timing time of the timer 13 is the disconnection time of the NFC communication connection; the first alarm module 12 can obtain the disconnection time of the current NFC communication connection in real time by reading the timing time of the timer 13 in real time.

Specifically, the threshold setting module 14 is used to preset an alarm time threshold. The first alarm module 12 is also used to obtain the alarm time threshold from the threshold setting module 14, and judge in real time whether the disconnection time of the current NFC communication connection is greater than the preset alarm time threshold; if so, send the first alarm. Otherwise, no first alarm is issued.

The alarm time threshold can be set according to actual needs; generally speaking, the time for customers to experience the product will not be too long, and the alarm time threshold can be set to five minutes or ten minutes, when the second terminal 20 is far away from the first terminal 10. If the set alarm time threshold is exceeded, the first alarm is triggered. The first alarm is an alarm sent by the first terminal 10. The alarm can be expressed in the form of sending an alarm sound, or a voice prompt, such as "The product experience time is too long, please pay attention " and other voice prompts.

In addition, the second terminal 20 can also issue an alarm synchronously. Since intelligent electronic products are generally integrated with 3G (3rd Generation, third-generation digital communication) communication modules or 4G (4th Generation, fourth-generation digital communication) communication modules, it can be realized through 3G communication modules or 4G communication modules.

Specifically, the second terminal 20 also includes a second alarm module 23 and a second long-distance connection module 24 ; the first terminal 10 also includes a first long-distance communication module 16 .

The first long-distance wireless communication module 16 and the second long-distance wireless communication module 24 are used to enable the first terminal and the second terminal to establish a long-distance wireless communication connection;

The first alarm module 12 is also used to send an alarm control signal to the second terminal 20 through the first long-distance wireless communication module 16 after sending out the first alarm; Receive the alarm control signal sent by the first terminal; and also send out the second alarm after receiving the alarm control signal sent by the first terminal 10 .

Wherein, the first long-distance communication module 16 and the second long-distance connection module 24 can adopt 3G communication module or 4G communication module, because the communication distance of 3G communication module or 4G communication module is relatively far, when the NFC communication connection is disconnected, the second The first long-distance communication module 16 and the second long-distance connection module 24 can still exchange data and information.

Among them, there may be other implementations for making the second terminal 20 send an alarm synchronously, all of which should be within the protection scope of the present invention. For example, the second terminal 20 is also provided with a timing device with a timing function. When the second terminal 20 detects When the NFC communication connection is disconnected, the timing device starts timing, and the second alarm module 23 detects in real time whether the disconnection time of the NFC communication connection is greater than the preset alarm time threshold, and if so, sends a second alarm.

Wherein, the content or alarm expression form of the second alarm may be the same as that of the first alarm, or may be set independently according to requirements.

Specifically, the first communication connection module 11 is further configured to send a notification to the first alarm module 12 to obtain a disconnection reconnection time after re-establishing the NFC communication connection with the second terminal 20 .

The first alarm module 12 is also used to notify the timer 13 to stop counting after receiving the notification of obtaining the reconnection time of the broken link, and to obtain the current counting time from the timer 13; After counting the time, the counting of the timer 13 is cleared.

Wherein, the current counting time obtained from the timer 13 is the link disconnection reconnection time taken from the disconnection of the NFC communication connection to the re-establishment of the NFC communication connection.

The first alarm module 12 is also configured to store the disconnection and reconnection time in a local memory.

Wherein, each time the NFC communication connection is disconnected until the NFC communication connection is re-established, the first alarm module 12 stores a reconnection time of the disconnection, and the memory 15 can store a plurality of reconnection times of the disconnection; the stored data can Through the NFC communication connection, the data is transmitted to any mobile phone or smart terminal with NFC function. The time of reconnection after a disconnection represents the time for a customer to experience the product. By analyzing and collecting multiple disconnection reconnection times, That is, the number of times the second terminal 20 is picked up can be known, and the duration of each time the second terminal 20 is picked up can be known, so that sales research and statistics can be performed more conveniently. And if the second terminal 20 is picked up for too long, an alarm will be triggered. At this time, as long as the second terminal 20 is put back on the first terminal 10, the alarm module can be turned off.

More specifically, in order to know the number of times the second terminal 20 is picked up more conveniently, the memory 15 is also used to create a record text for recording the number of times the NFC communication connection is disconnected. The first alarm module 12 is also configured to update the disconnection times of the NFC communication connection stored in the record text after receiving the notification of obtaining the disconnection reconnection time.

Every time the NFC communication connection is disconnected and when the NFC communication connection is re-established, the number of times of the NFC communication connection is increased once, and the first alarm module 12 is also used to update or reload all NFC communication connections after receiving the notification of the disconnection reconnection time. The number of times the NFC communication connection is disconnected stored in the record text.

The system provided by the embodiment of the present invention monitors the state of the NFC communication connection to determine whether the second terminal 20 is near the first terminal 10; Disconnect, by monitoring the disconnection time of the NFC communication connection, to obtain the time for the customer to experience the second terminal 20, and store this time as a data reference for market research on the product; when the disconnection time of the NFC communication connection exceeds When the preset alarm time threshold is reached, the first terminal 10 will send out the first alarm, reminding the staff that the second terminal 20 is far away from the first terminal for too long, and attention should be paid to prevent the product from being stolen; 20 to carry out wireless charging to ensure that the second terminal 20 has sufficient power; in addition, the present invention can realize the anti-theft monitoring function of the intelligent terminal without using traditional anti-theft locks, and compared with traditional electronic product display racks with anti-theft locks, it has a great The user experience of the second terminal 20 is improved.
