[0065] Figure 3 This is a schematic diagram of the module structure of the data writing prompt device of the present invention. DETAILED DESCRIPTION

[0066] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0067] The present invention provides a data writing prompt method, which is applied to a data writing prompt device, wherein the data writing prompt device is an electronic device supporting NFC communication, such as a mobile phone, a tablet, a wearable device or an audio-visual device; Figure 1 , Figure 1 This is a flow chart of a first embodiment of a data writing prompt method according to the present invention, wherein the method comprises the following steps:

[0068] Step S10: when an NFC tag is detected, obtaining the free storage space of the NFC tag;

[0069] An NFC tag consists of an NFC coil and an NFC chip. The NFC coil is a circular, elliptical, or other arbitrary coil formed by wrapping an NFC antenna around it. It captures electrical energy from the electromagnetic field and uses it to demodulate or modulate the electromagnetic field for transmission and reception of small amounts of data. The NFC chip is a circuit module used to store information. When a data input device is brought close to the NFC tag, the device emits electromagnetic energy to the NFC tag. The NFC coil on the NFC tag couples this electromagnetic energy and transmits it to the NFC chip, which is connected to the NFC coil. The NFC chip, through a rectifier circuit, converts this electromagnetic energy into power for its internal microcontroller, modem, and memory circuits. When the microcontroller, modem, and memory circuits are powered on and begin operating, they can transmit the information stored in the NFC chip to the data input device via the NFC coil. When the NFC coil in the data writing prompt device couples with the NFC coil in the NFC tag, the data writing prompt device detects the NFC tag and determines the tag's available storage space based on the information provided by the NFC tag. It should be noted that the NFC tag's available storage space can be retrieved after the write operation.

[0070] Step S20, receiving an NFC instruction to be written to the NFC tag, and determining whether the free storage space is smaller than the space occupied by the NFC instruction;

[0071] The display interface of the data writing prompt device is provided with a preset input position, such as an input box, in which the user can input the NFC instruction to be written to the NFC tag; it is understandable that the operation of writing the NFC instruction to the NFC tag will not be performed before the write instruction is received. The size of the space required is calculated based on the NFC instruction input by the user, and it is judged in real time whether the free storage space of the NFC tag can store the NFC instruction input by the user. Specifically, an instruction database can be pre-set, and the instruction database contains data information of each NFC instruction. The data information of the NFC instruction contains the length of the NFC instruction. At the same time, the size of the space required to be occupied by the NFC instruction can also be calculated based on the length. When it is necessary to calculate the occupied space of the NFC instruction, the corresponding data information can be directly matched in the instruction database to obtain the occupied space.

[0072] Step S30: If the free storage space is smaller than the space occupied by the NFC instruction, a prompt operation of insufficient space is performed.

[0073] When the free storage space is smaller than the space occupied by the NFC commands, it means that the NFC tag cannot store all the NFC commands entered by the user, so the insufficient space prompt operation is performed;

[0074] When the free storage space is greater than or equal to the space occupied by NFC commands, it indicates that the NFC tag can store all NFC commands entered by the user and does not prompt that there is insufficient space. It is understood that the NFC tag can store all NFC commands entered by the user and can prompt that there is sufficient space. Furthermore, the specific values of the occupied space and free storage space can be displayed at a preset space location, such as occupied space / free storage space: 20b / 1000b. It is understood that the specific prompt form can be set according to the actual application scenario and needs, and will not be detailed here.

[0075] This embodiment obtains the free storage space of the NFC tag and monitors the size relationship between the space occupied by the NFC instruction to be written and the free storage space to determine whether the NFC instruction to be written can be written into the NFC tag, and reminds the user when the NFC instruction to be written cannot be written into the NFC tag, so that the user can adjust and modify the NFC instruction according to the reminder before performing the writing operation, without having to repeat the operation.

[0076] Further, in the subsequent examples, see Figure 2 In the second embodiment of the data writing prompt method of the present invention proposed based on the first embodiment of the present invention, step S10 includes the following steps:

[0077] Step S11, obtaining the address range where the NFC tag can currently write data;

[0078] Step S12: Calculate the free storage space of the NFC tag according to the address range.

[0079] The NFC tag's response contains the address range where data can be written (starting address startAddr, ending address endAddr). The free memory space can be calculated based on the address range. For example, if the address range is [252, 1252], the free memory space is 1252-252 = 1000 bytes.

[0080] It should be noted that the calculation operation of the free storage space can also be directly calculated by the NFC tag, and the NFC tag directly feeds back the free storage space to the data writing prompt device.

[0081] This embodiment can reasonably obtain the free storage space of the NFC tag.

[0082] Furthermore, in a third embodiment of the data writing prompt method of the present invention proposed based on the first embodiment of the present invention, step S20 includes the following steps:

[0083] Step S21, sorting the received NFC instructions according to the corresponding instruction serial numbers to obtain an instruction sequence;

[0084] The step S21 includes:

[0085] Step S211, obtaining the receiving time or occupied space corresponding to each NFC instruction;

[0086] Step S212, generating a command sequence number corresponding to each NFC according to the reception time, the occupied space or randomly;

[0087] Step S213: sort the received NFC instructions according to the instruction sequence numbers to obtain the instruction sequence.

[0088] In this embodiment, the instruction sequence is obtained by sorting the NFC instructions by receiving time, occupied space or randomly, wherein sorting by receiving time can meet the user's usage needs; sorting by occupied space can make it possible to write as many NFC instructions as possible into the NFC tag when there is free storage space that cannot store all NFC instructions. Specifically, when the order requirement or correlation between NFC instructions is small, the NFC instructions can be sorted by space size; when the order requirement or correlation between NFC instructions is large, the NFC instructions can be sorted by receiving time; it is also set according to the actual application scenario and needs, which will not be described in detail here. Step S22, sequentially combine the first a NFC instructions in the instruction sequence to obtain a number of combination sequences of NFC instructions, where 1≤a≤the number of NFC instructions;

[0089] Step S23, determining in sequence whether the occupied space of each combination sequence is greater than the free storage space;

[0090] Step S24: If there is a combination sequence whose occupied space is larger than the free storage space, it is determined that the free storage space is smaller than the occupied space of the NFC instruction.

[0091] The NFC commands input by the user are combined to obtain a combination sequence. Specifically, if the user inputs 4 NFC commands, that is, 1≤a≤4; they are sorted according to the reception time as command 1, command 2, command 3 and command 4 respectively; and four combination sequences are obtained: [command 1]; [command 1; command 2]; [command 1; command 2; command 3]; [command 1; command 2; command 3; command 4].

[0092] The space occupied by each combination sequence is the sum of the space occupied by the instructions it contains; whether the space occupied by each combination sequence is greater than the free storage space is determined in turn; when the space occupied by all combination sequences is less than or equal to the free storage space, it means that the free storage space is greater than or equal to the space occupied by the NFC instructions; it should be noted that it is also possible to determine whether the space occupied by the largest combination sequence is greater than the free storage space to determine whether the free storage space is less than the space occupied by the NFC instructions; when there is a combination sequence whose occupied space is greater than the free storage space, it means that the free storage space of the NFC tag cannot store all NFC instructions.

[0093] This embodiment can reasonably determine whether the free storage space is smaller than the space occupied by the NFC command.

[0094] Furthermore, in a fourth embodiment of the data writing prompt method of the present invention proposed based on the third embodiment of the present invention, step S23 includes the following steps:

[0095] Step S231, incrementing the counter b by 1, and determining whether the occupied space of the combined sequence including the current b write instructions is larger than the free storage space;

[0096] In step S232, if the space occupied by the combined sequence including the current b write instructions is less than or equal to the free storage space, then when b is less than the number of the NFC instructions, executing the following steps: incrementing the counter b by 1, and determining whether the combined sequence including the b write instructions can be stored in the free storage space; when b is greater than or equal to the number of the NFC instructions, the free storage space can store the NFC instructions, and all NFC instructions can be displayed at the preset input position with the first preset parameters.

[0097] Step S233: If the space occupied by the combined sequence including the current b write instructions is larger than the free storage space, it is determined that the free storage space cannot store the NFC instruction.

[0098] It is understandable that the counter will be reset when it is started. The space occupied by each combination sequence, from the smallest to the largest number of NFC instructions, is determined to see if it is greater than the free storage space. If the space occupied by a combination sequence is less than or equal to the free storage space, the next combination sequence is determined. If the space occupied by a combination sequence is greater than the free storage space, it is considered that the current combination sequence and the combination sequence containing more NFC instructions than the current combination sequence cannot be stored in the NFC tag.

[0099] The step S30 includes the following steps:

[0100] Step S31: classify the NFC instructions b and thereafter in the instruction sequence as first instructions, and classify the NFC instructions before b in the instruction sequence as second instructions, wherein the first instructions are instructions that cannot be written into the NFC tag, and the second instructions are instructions that can be written into the NFC tag;

[0101] Step S32: displaying the first instruction with a first preset parameter, and displaying the second instruction with a second preset parameter.

[0102] It can be made clear from the way the combined sequence is generated and whether the occupied space is greater than the free storage space that when it is judged that the occupied space of the combined sequence is greater than the free storage space, it means that the space required to be occupied by the NFC instructions other than the last NFC instruction in the combined sequence is less than or equal to the free storage space. At the same time, since the order of the NFC instructions in the combined sequence is consistent with that in the instruction sequence, the NFC instructions before the bth in the instruction sequence can be classified as instructions that can be written into the NFC tag, and the NFC instructions from the bth onwards in the instruction sequence can be classified as instructions that cannot be written into the NFC tag.

[0103] The first and second preset parameters are used to distinguish the first and second instructions; specific parameters include, but are not limited to, color, size, font, or mark, such as displaying the first instruction in red and the second instruction in green. In other embodiments, a separation process may be performed between the first and second instructions, such as by setting a dividing line between the first and second instructions. It is understood that any method for displaying or distinguishing between two types of objects can be applied to the solution of this embodiment.

[0104] This embodiment can reasonably distinguish between the first instruction and the second instruction, so that the user can clearly understand which instructions exceed the free storage space.

[0105] Furthermore, in a fifth embodiment of the data writing prompt method of the present invention proposed based on the first embodiment of the present invention, if the free storage space is smaller than the space occupied by the NFC instruction, the method further includes the steps of:

[0106] Step S40: Obtain a first instruction, and match a recommended instruction in a preset instruction library that can implement the function of the first instruction and whose space occupied by the NFC instruction is less than or equal to the free storage space, wherein the first instruction is an instruction that cannot be written into the NFC tag;

[0107] Step S50, displaying the recommended instruction at a preset recommended instruction display position corresponding to the first instruction;

[0108] Step S60: When a selection signal corresponding to the recommended instruction is received, the first instruction is replaced with the recommended instruction.

[0109] When the free storage space is smaller than the space occupied by the NFC instructions, the NFC instructions contain instructions that cannot be written into the NFC tag, namely, the first instructions. To further improve the user experience, an instruction with the same or similar function as the first instruction can be matched, and the space occupied by the NFC instruction formed after adopting the instruction is less than or equal to the free storage space. That is, while the function of the NFC instruction remains unchanged, an NFC instruction with a smaller space is provided for the user to choose. It is understandable that multiple first instructions can be matched with corresponding recommended instructions at the same time. Furthermore, the second instruction, i.e., the instruction that can be written into the NFC tag, can also be synchronously matched with the corresponding recommended instruction to further reduce the space occupied by the NFC instructions.

[0110] When the user selects a recommended instruction, the recommended instruction replaces its corresponding first instruction.

[0111] This embodiment can provide NFC commands that occupy less space for users to select without changing the functions of the NFC commands.

[0112] It should be noted that for the aforementioned method embodiments, for the sake of simplicity, they are all expressed as a series of action combinations, but those skilled in the art should be aware that this application is not limited by the order of the actions described, because according to this application, certain steps can be performed in other orders or simultaneously.

Based on this understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present application.
