Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
The embodiment of the invention provides an NFC triggering method, as shown in fig. 1, which comprises the following steps:
step 101: when an NFC tag is sensed, acquiring a first sensing moment when the NFC tag is sensed;
step 102: acquiring the writing time of the NFC tag for completing writing data and the preset delay trigger time;

Specifically, NFC (Near Field Communication, abbreviated as NFC) is a fast short-range high-frequency wireless communication technology that operates at a frequency of 13.56MHz (megahertz), the communication connection establishment time is less than 1 second, and the communication distance is generally limited to within 10 cm.
NFC tags, including NFC coil, NFC chip, can communicate with NFC induction device. NFC coils, which are coils around which an NFC antenna is wound in a circular or oval shape or any other shape, are used to capture electrical energy from an electromagnetic field and to carry out transception communications carrying smaller amounts of data by demodulating or modulating the electromagnetic field. The NFC chip is used for storing chips of the circuit module of the information. The NFC sensing device may be an NFC reader-writer, or may be an electronic device supporting NFC communications, such as a mobile phone supporting NFC communications. When the NFC equipment induction equipment is close to the NFC tag, the NFC induction equipment emits electromagnetic energy to the NFC tag, an NFC coil on the NFC tag couples the electromagnetic energy and transmits the electromagnetic energy to an NFC chip connected with the NFC coil, and the NFC chip converts the electromagnetic energy into a power supply required by circuits such as a microcontroller, a modem, a memory and the like in the NFC chip through a rectifying circuit. When circuits such as a microcontroller, a modem, a memory and the like start to work after power is applied, information stored in the NFC chip can be sent to the NFC induction device through the NFC coil.
For example, the NFC tag may communicate with a portable communication device such as a mobile phone with NFC functionality, so that the operating state of the device may be changed or related software and settings may be opened. The NFC label stores data written in advance into the mobile phone (with NFC function), when the mobile phone with NFC function is close to the NFC label, the mobile phone can switch the working state of the mobile phone through mobile phone software after sensing the NFC label and effectively identifying, such as automatically opening navigation, automatically entering a conference mode, automatically connecting a designated Wifi hotspot, automatically listening to music, automatically closing Wifi signals, entering a flight mode and the like.
In practical application, when the NFC device writes data into the NFC tag, the NFC tag starts to work. When the NFC tag after writing data is in the induction range of the NFC device, false triggering instructions can occur when the NFC device moves randomly, and therefore false triggering is caused. In this way, for some disposable effective NFC tags, the NFC tag needs to be reset due to false triggering, which reduces the user experience.
Based on this, the embodiment provides an NFC triggering method, which can reduce sensitivity of NFC triggering, improve security of NFC triggering, and promote user experience.
Specifically, the embodiment may be applied to an NFC device, and when the NFC device senses an NFC tag, obtain a first sensing time when the NFC tag is sensed. Here, the first sensing timing is accurate to seconds or milliseconds, or the like.
Further, in an embodiment, the obtaining the writing time when the NFC tag completes writing the data and the preset delay trigger time includes:
and reading the writing time of the NFC label for finishing writing the data and the preset delay trigger time from the NFC label.
In practical application, after finishing the data writing operation on the NFC tag, the NFC device may store the finishing time of the data writing operation on the NFC tag, the identification information of the NFC tag, and the delay trigger duration corresponding to the NFC tag into the NFC tag. When NFC equipment senses an NFC tag, the writing time and the preset delay trigger time in the NFC tag are obtained.
Here, the preset delay trigger duration may be set according to actual situations. For example, the delay trigger duration is set to 3 seconds.
In addition, the identification information here may be an ID of the NFC tag, which is used to distinguish the NFC tag from other NFC tags. Generally, an NFC tag is provided with an ID.
In addition, in an embodiment, the obtaining the writing time when the NFC tag completes writing the data and the preset delay trigger time includes:
reading identification information of the NFC tag from the NFC tag;
acquiring writing time and preset delay trigger time corresponding to the identification information from a preset database according to the identification information; the preset database stores the corresponding relation between the identification information and the writing time and the delay trigger time respectively.
In practical application, after finishing the data writing operation on the NFC tag, the NFC device may store the finishing time of the data writing operation on the NFC tag, the identification information of the NFC tag, and the delay trigger duration corresponding to the NFC tag in the preset database correspondingly. When NFC equipment senses the NFC tag, the identification information of the NFC tag can be obtained from the NFC tag, and the writing time and the preset delay trigger time corresponding to the identification information are obtained from the preset database according to the identification information.
Here, the preset delay trigger duration may be set according to actual situations. For example, the delay trigger duration is set to 3 seconds.
In addition, the identification information here may be an ID of the NFC tag, which is used to distinguish the NFC tag from other NFC tags. Generally, an NFC tag is provided with an ID.
Here, the preset delay trigger duration may be determined according to the tag type of NFC, in addition to the identification information. For example, when the tag type of the NFC tag is a, the corresponding delay trigger duration is 3 seconds; when the label type of the NFC label is B, the corresponding delay triggering time is 5 seconds. Here, the plurality of NFC tags may correspond to the same tag type.
In addition, when the delay trigger time length of the NFC tag is set, the tag type of the NFC tag may be obtained first, and the delay trigger time length corresponding to the tag type is determined according to the tag type of the NFC tag, and the delay trigger time length is used as the delay trigger time length of the NFC tag.
Further, in an embodiment, the obtaining the writing time when the NFC tag completes writing the data and the preset delay trigger time includes:
reading identification information and tag type of the NFC tag from the NFC tag;
acquiring writing time corresponding to the identification information from a preset database according to the identification information, and acquiring delay trigger time corresponding to the tag type from the preset database according to the tag type; the preset database stores the corresponding relation between the identification information and the writing time, and the preset database also stores the corresponding relation between the label type and the delay trigger time.
In practical application, after finishing the data writing operation on the NFC tag, the NFC device may store the finishing time of the data writing operation on the NFC tag, the identification information of the NFC tag, the tag type of the NFC tag, and the delay trigger duration corresponding to the NFC tag in the preset database correspondingly. When NFC equipment senses the NFC tag, the identification information and the tag type of the NFC tag can be obtained from the NFC tag, the writing time corresponding to the identification information is obtained from a preset database according to the identification information, and the delay trigger time corresponding to the tag type is obtained from the preset database according to the tag type.
Of course, in actual application, after finishing the writing data operation on the NFC tag, the NFC device may store the finishing time of the writing data operation on the NFC tag, the identification information of the NFC tag, the tag type of the NFC tag, and the delay trigger duration corresponding to the NFC tag in the NFC tag correspondingly. Therefore, when the NFC equipment senses the NFC tag, the finishing moment of the data writing operation of the NFC tag, the identification information of the NFC tag, the tag type of the NFC tag and the delay triggering time corresponding to the NFC tag can be obtained from the NFC tag.
In addition, to further improve the technical effect of the implementation and improve the user experience, in an embodiment, the method further includes:
when the difference between the first sensing time and the writing time is smaller than or equal to the delay trigger time, reporting errors or prompting the residual waiting time; the residual waiting time is the difference between the current time and a second sensing time, and the second sensing time is the time when the difference between the second sensing time and the writing time is equal to the delay trigger time.
Here, the error reporting may be performed by means of voice prompt, or may be performed by means of flashing light. In addition, besides error reporting, the method can also prompt the residual waiting time, so that the user can conveniently wait for a certain time to finish triggering operation.
According to the embodiment, after the NFC tag finishes the data writing operation, the NFC tag can be triggered by delaying a certain time through setting the delay triggering time length, so that the influence on the user experience caused by false triggering of the NFC tag due to movement of the NFC device after the NFC tag finishes the data writing operation is avoided.
Here, in practical application, the delay process may be implemented by hardware such as a delay circuit.
According to the NFC triggering method provided by the embodiment of the invention, when an NFC label is sensed, a first sensing moment when the NFC label is sensed is obtained; acquiring the writing time of the NFC tag for completing writing data and the preset delay trigger time; judging whether the difference between the first sensing time and the writing time is larger than the delay triggering time length or not; and when the difference between the first sensing time and the writing time is larger than the delay trigger time, acquiring and executing the instruction in the NFC tag. The scheme provided by the invention can reduce the sensitivity of NFC triggering and improve the safety of NFC triggering.
The present invention will be described in further detail with reference to examples of application.
According to the application embodiment, after the NFC tag writes data, the NFC tag can be triggered by delaying a certain time through setting delay triggering time length, so that the influence on the user experience caused by false triggering of the NFC tag due to movement of NFC equipment after the NFC tag finishes writing data is avoided.
Specifically, the embodiment may set a specific case or a specific instruction of the delay circuit application, that is, only under a certain number of instructions or in a specific scene, the delay circuit is turned on. Specifically, when the NFC device completes writing a special instruction (such as a one-time instruction) to the NFC tag, the current network time is obtained as the writing time, the duration of a required interval between the writing instruction and the first trigger is set, and the ID of the NFC tag, the corresponding writing time and the preset duration are recorded in the database. (of course, the writing time and the preset duration here may also be recorded in the NFC tag)
Further, the embodiment scheme includes:
step 1: when an NFC tag is sensed, information in the NFC tag is acquired, wherein the information comprises a tag ID, an instruction combination and a trigger time condition (for example, a time delay time length is stored in a database of the NFC device instead of the tag); and recording the reading time;
here, the trigger time condition may be a delay of 5 minutes or, in particular, several minutes.
In practical application, the corresponding delay time length can be searched according to the tag type, and the delay time length can also be searched according to the ID of the NFC tag. Here, one tag type corresponds to one delay time period.
Step 2: acquiring a first sensing moment of local sensing;
step 3: judging whether the difference value between the first sensing time and the read-write time meets the trigger time condition or not;
step 4: and if yes, triggering the instruction combination.
If the difference between the first sensing time and the read-write time does not meet the trigger time condition (i.e. is not longer than the delay time), the error is reported or the remaining time is prompted, so that the user can wait conveniently.
According to the method and the device, whether the first sensing time of the NFC tag reaches the delay time is judged by recording the writing time and the preset interval time, when the difference between the first sensing time of the NFC tag and the writing time is larger than the delay time, triggering is achieved, false triggering caused by the fact that the NFC tag finishes writing operation is avoided, triggering safety of the NFC tag is improved, and user experience is improved.
