Based on this, a technical solution is needed that can facilitate the product server to obtain the number of times of use of each function supported by the user on the home appliance product.

Disclosure of Invention

In view of the above technical problems, the present specification provides the following technical solutions:

in a first aspect, a data acquisition method based on NFC is provided, where a home appliance includes a work control module and an NFC module, and a data area of the NFC module of the home appliance is used to record the number of times that at least some functions of the home appliance are used, where the at least some functions are used to implement the main use of the home appliance; the data area is also used for recording control instructions provided for the work control module; the method comprises the following steps:

the work control module monitors used events corresponding to at least part of functions of the household appliance, reads the used times corresponding to the functions from the data area and adds 1 after monitoring the used events corresponding to any function each time, and writes the updated used times into the data area;

responding to a request of a user by a product application installed on user equipment, writing a control instruction into the data area by utilizing communication connection between an NFC module of the user equipment and an NFC module of the household appliance product, and reading the used times corresponding to at least part of functions from the data area by utilizing the communication connection;

and the product application uploads the read used times corresponding to at least part of functions to a product server.

In the above technical solution, the home appliance is configured with the NFC module, and the operation control module of the home appliance may monitor an event that the main-way function supported by the home appliance is used by the user, and add 1 to the number of times that the main-way function is used in the data area of the NFC module each time the event that the main-way function is used by the user is monitored.

As for how to inform the product service end of the used times of the main-path function, the concept in the scheme is as follows:

the product application is provided for a user, the product application is installed on user equipment, the user can interact with the product application and send a request to the product application, and instruction transmission of a work control module of the household appliance product is achieved. Particularly, the user can be close to the NFC module of household electrical appliances with user equipment's NFC module, establishes communication connection, and the product is used and is utilized this communication connection to write in control command in the data area of the NFC module of household electrical appliances, and work control module can read this control command from the data area of NFC module to realized that the user gives the instruction to the built-in work control module of household electrical appliances.

The key point here is that, the user is holding the purpose of "giving the instruction to the work control module", is close to the NFC module of household electrical appliances with the NFC module of user equipment, and the product application can be in the same direction as reading the number of times of being used of main journey function in the data zone of the NFC module of household electrical appliances, and then, the product application can upload the number of times of being used of reading to the product service end, and the operation of acquireing and uploading the number of times of being used is whole journey not perceptive to the user, can not cause the disturbance for the user.

Particularly, the product design can attract users to frequently transmit instructions to the work control module of the household appliance in a 'touch and touch' mode, so that the product service end can frequently acquire the latest used times of the main-use functions of the household appliance, and the product service end can conveniently and timely optimize the main-use functions of the household appliance.

In some embodiments, the data area is a custom data area configured to use a non-NFC data exchange format recognizable by a product application, and the custom data area is readable and writable by an operating system of the user mobile device.

Generally, NFC enabled devices will default to supporting the NFC protocol and may identify NFC records in the NFC data area that have a common NFC data exchange format. If the device vendor defines other kinds of NFC data exchange formats, logic for identifying NFC records of the other kinds of NFC data exchange formats is also built into the operating system of the factory device.

In practical applications, some important service data (such as the number of times of using the main in-transit function) may need to be stored in the data area of the NFC module of the home appliance, and a manufacturer of the home appliance sometimes wants, in view of safety of the important service data, that an operating system (maintained by the manufacturer of the user equipment) of the user equipment is only readable and not writable for data in NFC without permission. In other words, it is necessary that the operating system of the user mobile device cannot rewrite data in the NFC module of the home appliance product under a default condition, and that the operating system of the user mobile device writes data, such as a user identifier, distribution network information provided by the user, and a control instruction, into the NFC of the home appliance product when the operating system of the user mobile device is required by a manufacturer of the home appliance product.

For this reason, a data area that cannot be identified by the operating system of the user equipment may be added to the data area of the NFC module of the home appliance product, and for convenience of description, the added data area is referred to as a (home appliance manufacturer) custom data area, and the custom data area uses a non-NFC data exchange format (a data exchange format agreed by a private protocol of the home appliance manufacturer, which may also be referred to as a private data exchange format).

Since the data exchange format used in the custom data area is not the NFC data exchange format specified by the NFC protocol, the operating system of the user equipment cannot recognize the data in the custom data area even if the operating system can read the data in the custom data through the NFC module of the user mobile device.

Correspondingly, for important service data in the custom data area, only software (a product service end system, product application, and a work control module in a household appliance) developed by a product manufacturer can be identified. Therefore, under the condition that the NFC module of the home appliance product has the custom data area, the user equipment needs to install the product application, and after the product application is started, the product application identifies data in the custom data area read by the NFC module of the user mobile equipment, and in addition, the product application can call the operating system of the user equipment to write data in the custom data area.

Therefore, through the above series of technical settings, the user equipment needs to write data into the product NFC module, and uniformly writes the data into the custom data area. The data in the NFC module of the household appliance cannot be rewritten by the operating system of the user equipment under the default condition, and the data can be written into the NFC module of the household appliance under the control of the installed product application.

In some embodiments, the data area includes a first data area and a second data area, the first data area is used for recording the number of times of use corresponding to at least part of functions of the household appliance, and the second data area is used for recording control instructions provided to the work control module;

reading the used times corresponding to the function from the data area and adding 1, and writing the updated used times into the data area, wherein the method comprises the following steps:

reading the used times corresponding to the function from the first data area, adding 1, and writing the updated used times into the first data area;

writing a control command to the data area, including:

writing a control command into the second data area;

reading the number of times of use corresponding to at least part of functions from the data area, including:

and reading the used times corresponding to the at least part of functions from the first data area.

If the first data area dedicated to recording the number of times of use and the second data area dedicated to receiving the control command are not divided in the data area of the household appliance, the logic for the work control module to read the control command from the data area is complex (the logic for searching data needs to be added), and the logic for the product application to read the number of times of use from the data area is complex (the logic for searching data needs to be added). If the first data area and the second data area are arranged, the product application can read data from a specific position, the read data is the required use frequency information, the work control module can also read data from the specific position, and the read data is the required control instruction information, so that the development difficulty of the product application and the work control module can be reduced.

In some embodiments, the data area further includes a third data area for recording at least one of the following information:

the first mark information which is written by the work control module and used for indicating whether the data area is initialized or not;

Detailed Description

First, it should be noted that the technical solution provided in the present disclosure relates to obtaining data (mainly, the number of times that a user uses each function supported by a home appliance) generated during a process of using the home appliance by the user, where the obtaining is performed on the premise of user authorization. For example, before a user uses a home appliance, the user usually needs to read a usage protocol associated with the home appliance, the usage protocol usually explicitly prompts the user, the user may count the number of times that the user uses each function in the process of using the product, and the user needs to explicitly confirm that the user agrees to the usage protocol.

The household appliance product described herein generally refers to electric appliances with various purposes applied to a home environment or other environments, and specifically may be a cooking appliance with a certain cooking function, such as an electric pressure cooker, an electric frying pan, a wall breaking machine, a juice extractor, and the like. In addition, the cooking appliance can also be a multifunctional cooking appliance with various cooking functions.

The home appliances described in this specification have the conventional structure and functions (such as product housing, power interface, basic home appliance functions, etc.) of the home appliances on the market at present, and are not specifically described herein.

An optional implementation scheme is that a work control module of the household appliance product monitors the number of times of use of functions supported by the household appliance product, and then sends the number of times of use to a product server through wireless network connection between a Wi-Fi module of the household appliance product and the product server. However, some home appliances do not have a Wi-Fi module (which is costly), meaning that these home appliances cannot communicate with the product server via a wireless network connection; even if the household appliance product is provided with the Wi-Fi module, the using times cannot be uploaded to the product server under the condition that the Wi-Fi module is damaged or closed.

Therefore, a technical scheme which is independent of a Wi-Fi module and can facilitate a product server to obtain the use times of each function supported by a user on a household appliance is needed.

To this end, in another technical solution provided in this specification, the home appliance is configured with an NFC module, and the operation control module of the home appliance may monitor an event that a main-way function supported by the home appliance is used by a user, and add 1 to the number of times that the main-way function is used in a data area of the NFC module each time the event that the main-way function is used by the user is monitored.

the product application is provided for a user, the product application is installed on user equipment, the user can interact with the product application and send a request to the product application, and instruction transmission of a work control module of the household appliance product is achieved. Specifically, the user can be close to the NFC module of household electrical appliances with the NFC module of user equipment, establish communication connection, and the control command is write in to the data area of the NFC module of household electrical appliances to product application utilization this communication connection, and this control command can be read from the data area of NFC module to work control module to realized that the user gives the instruction to the built-in work control module of household electrical appliances.

Particularly, because the product design can attract a user to frequently transmit instructions to the work control module of the household appliance product in a 'touch-and-dash' mode, the product service end can frequently acquire the latest used times of the main-use functions of the household appliance product, so that the product service end can timely optimize the main-use functions of the household appliance product.

Fig. 1 is a schematic flowchart of a data acquisition method based on NFC provided in this specification, and includes:

s100: the work control module monitors used events corresponding to at least partial functions of the household appliance.

S102: and after monitoring the used event corresponding to any function each time, the work control module reads the used times corresponding to the function from the data area, adds 1 to the used times, and writes the updated used times into the data area.

S104: and responding to a request of a user by a product application installed on user equipment, and writing a control instruction into the data area by utilizing the communication connection between the NFC module of the user equipment and the NFC module of the household appliance product.

S106: and the product application reads the used times corresponding to at least part of functions from the data area by utilizing the communication connection.

S108: and the product application uploads the read used times corresponding to at least part of functions to the product server.

In the method flow shown in fig. 1, a home appliance includes a work control module and an NFC module, where a data area of the NFC module of the home appliance is used to record the number of times that at least some functions of the home appliance are used, where the at least some functions are used to implement the main use of the home appliance; the data area is also used for recording control instructions provided for the work control module.

In addition, the household appliance product can comprise a Wi-Fi module or not.

The work control module is a core control module of the household appliance, and is also commonly referred to as an MCU module in the industry. The work control module can control the household appliance to realize various purposes of the household appliance, wherein the purposes comprise a primary purpose and a secondary purpose. The main use of the household electrical appliance is the main use expected by a user to purchase the household electrical appliance. For example, if the home appliance is a television, watching a video program is the primary use of the home appliance, and connecting to a wireless network, browsing a web page, and projecting a screen is the secondary use. For another example, if the household appliance is a cooking appliance, the cooking menu is the main purpose of the household appliance, and the purposes of 'touch and collision' realized by the NFC module, wireless network connection by the Wi-Fi module, voice broadcast and the like are secondary purposes.

Because the work control module is responsible for controlling the household appliances to work, if a user wants to use the main purpose functions of the household appliances, the user needs to pass through the work control module, and therefore the work control module can monitor the used events of the main purpose functions.

In some embodiments, the user may directly operate on the home appliance, for example, press a button on the appearance of the home appliance or interact with a touch screen provided in the home appliance, and communicate a control instruction to the home appliance control module to implement a primary function, such as a cooking recipe. It should be noted that the control instruction may instruct the work control module to implement a primary-use function, or may instruct the work control module to implement a secondary-use function.

In other embodiments, the user may implement issuing the control instruction to the work control module by using a product application installed on the user device (which may be a mobile device, such as a mobile phone). And the product application responds to the request of the user, and writes a control instruction into the data area by utilizing the communication connection between the NFC module of the user equipment and the NFC module of the household appliance product. The work control module can read the control instruction from the data area to start work.

writing a control command to the data area, comprising:

writing a control command into the second data area;

and reading the used times corresponding to at least part of functions from the first data area.

Fig. 2 is a schematic diagram of an NFC-based data acquisition method provided in this specification.

second flag information for determining whether or not a control command, which has not been read by the product built-in module, exists in the second data area; after the product application writes the control instruction into the second data area, setting the second flag information to represent a positive judgment result; the product built-in module sets the second flag information to represent a negative judgment result after reading the control instruction from the second data area;

the third mark information which is written by the work control module and used for representing the working state of the household appliance product; the working states of the household appliance comprise shutdown, standby, failure and working;

and the fourth flag information is written by the work control module and is used for indicating the error type of the product application write data error.

The data area can also comprise a third data area for recording some state information, which is convenient for recording the working state of the household appliance or the interaction state of the household appliance and the product application, and the state information also belongs to important service data of the household appliance manufacturer.

It should be noted here that, with respect to the first flag information, the effect is that it is possible to avoid adverse effects on the lifetime of the NFC chip caused by repeatedly initializing the NFC data area.

In some embodiments, the work control module reads the control instruction from the data area, and starts one or more functions for implementing a main purpose of the home appliance according to the control instruction.

In some embodiments, the product service end determines a user preference level for each of the plurality of recipes based on a number of times that the at least part of the function uploaded by the product application is used.

In some embodiments, the product server determines a menu list based on the preference degree of the user for each menu of the plurality of menus, and issues the menu list to the product application, so that when the product application subsequently writes a control instruction into the data area, the menu list is written into the data area, and further the work control module obtains the menu list and updates the menu list stored locally.

An example is given here.

The cooking appliance is wall breaking equipment, a user purchases the equipment in 9 months and 2 days, a data structure is stored in an equipment self-defining data area, the data structure can be 24-bit numbers, wherein every continuous 4 numbers represent the used times corresponding to a main purpose function, and in an initialization state, the 24-bit numbers are 0 and do not store the used times of any main purpose function. And when the mobile phone App interacts with the NFC module of the equipment, the mobile phone App reads the number and reports the number and the model of the equipment to the product server. And 9, month and 11, the user interacts with the NFC module of the equipment again by using the mobile phone App, and the read number is 001300050026000700120002 and the model of the equipment is reported to the product server.

The product server side finds a corresponding main purpose function list according to the equipment model, namely a wall breaking machine, the main purpose functions (menu) corresponding to the 24-digit numbers in sequence are A-milkshake, B-corn juice, C-soybean milk, D-rice paste, E-fruit juice and F-health-preserving pottage, and can know that the user uses 13 milkshake menus, 5 corn juice menus, 26 soybean milk menus, 7 rice paste menus, 12 fruit juice menus and 2 health-preserving pottage menus in 9 days from 2 days of 9 months to 11 days of 9 months.

And the product server-side realizes personalized recommendation or provides a basis for updating the function design of subsequent products according to the used times of the main use functions. For example, the product service end may analyze the cooking habits of the users of the devices and generate a device function diagram (as shown in fig. 3).

In addition, if the work control module is configured as a product built-in module of the home appliance, and the control instruction is configured as interactive data provided by the user side to the product built-in module, the present disclosure further provides a data interaction scheme between the home appliance and the user. The embodiments described hereinbefore may be combined with the embodiments described hereinafter.

A data interaction method between a household appliance and a user is provided, wherein the household appliance comprises a built-in module and an NFC module, and a data area of the NFC module of the household appliance comprises a first data area and a second data area; the method comprises the following steps:

the product built-in module writes first interactive data into the first data area, wherein the first interactive data is data to be provided for a user by the household appliance;

the product application installed on the user equipment reads first interactive data from the first data area by utilizing the communication connection between the NFC module of the user equipment and the NFC module of the household appliance product;

and

the product application writes second interactive data into the second data area by utilizing the communication connection between the NFC module of the user equipment and the NFC module of the household appliance product, wherein the second interactive data is data to be provided for the household appliance product by the user;

and the product built-in module reads the second interactive data from the second data area.

In the above technical solution, the NFC module is configured for the home appliance, and the product application corresponding to the home appliance is installed on the user equipment (the home appliance and the product application are produced or developed by the same manufacturer), so that the user can use the NFC connection between the NFC module of the user equipment and the NFC module of the home appliance to operate the product application to interact with the home appliance. Meanwhile, a first data area and a second data area are arranged in the data area of the NFC module, the first data area is an area (readable and unwritable on the user side) dedicated to storing first interactive data provided by the household appliance to the user, and the second data area is an area (readable and unwritable on the household appliance side) dedicated to storing second interactive data provided by the user to the household appliance. Because the first data area and the second data area are isolated from each other, data writing conflict between the user side and the household appliance side can be avoided.

It should be noted here that if the first data area and the second data area are not provided, such a situation is easily occurred: in the same time period, the product side needs to write the first interactive data into the data area, and the user side needs to write the second interactive data into the data area, which is the data write conflict between the user side and the household appliance side. The NFC module does not support a write-in lock mechanism, so that when data write-in conflict occurs between the user side and the home appliance side, write-in failure is easily caused on one side, and when write-in failure occurs on the user side, poor product use experience is brought to the user. Therefore, the first data area and the second data area are arranged, so that data writing conflict between the user side and the household appliance side can be avoided.

And if the household appliance needs to provide the first interactive data for the user, the household appliance writes the first interactive data into the first data area so that the product application can read the first interactive data from the first data area by utilizing the NFC connection. And if the user needs to provide the second interactive data to the household appliance, the user writes the second interactive data into the second data area so that the household appliance can obtain the second interactive data.

It should be noted that the home appliance obtains the second interactive data, which may specifically be that a built-in module of the home appliance obtains the second interactive data. The product built-in module of the home appliance product is not particularly limited in the present disclosure, and may be, for example, a work control module (generally referred to as an MCU control board) of the home appliance product, a Wi-Fi module of the home appliance product, or other product built-in modules that need to obtain interactive data from a user side.

In some embodiments, the first interaction data comprises: the method comprises the steps of obtaining the number of used times corresponding to at least part of functions of the household appliance, wherein the at least part of functions are used for realizing the main purpose of the household appliance.

At present, the functions supported by household appliances on the market are gradually diversified, and the product server expects to know the use times of the user for each function supported by the household appliances, so that the preference condition of the user for each function supported by the household appliances is analyzed, and the functions supported by the products are optimized. By means of the embodiment, under the condition that the household appliance does not have the network communication capability (for example, the household appliance does not have the Wi-Fi module, or the Wi-Fi module of the household appliance is not activated and fails), the product application can acquire the used times corresponding to at least part of functions of the household appliance, and then upload the used times to the product server.

In some embodiments, the second interaction data comprises: network distribution information; the product built-in module includes: wi-Fi module of household electrical appliances.

In the case that the home appliance has a Wi-Fi module, the user may provide the distribution network information (such as SSID and password of the wireless lan) to the Wi-Fi module of the home appliance through this embodiment.

In some embodiments, the second interaction data comprises: a control instruction; the product built-in module includes: and the work control module of the household appliance is used for controlling the household appliance to realize the corresponding work flow according to the control instruction.

Some household appliances support users to issue control instructions, and users can issue control instructions to the household appliances through the embodiment. For example, when the home appliance is a cooking appliance, a user may issue a control instruction for cooking a certain dish to a work control module of the home appliance, so that the work control module of the home appliance starts a corresponding work flow.

In some embodiments, the data area further includes a third data area for recording at least one of the following information: the product built-in module is a work control module of a household appliance product;

the first mark information is written by the work control module and is used for indicating whether the data area is initialized;

second mark information used for judging whether second interactive data which are not read by the product built-in module exist in the second data area; after writing the second interactive data into the second data area, the product application sets the second flag information to represent a positive judgment result; the product built-in module sets the second flag information to represent a negative judgment result after reading the second interactive data from the second data area;

and the fourth mark information is written by the product application and is used for indicating the error type of the data writing error of the product application.

In addition, in some embodiments, the third data area may further include at least one of the following information:

the fourth mark information written by the work control module is used for representing: when the household appliance is a cooking appliance, the work control module of the cooking appliance writes the identification of the menu which is currently cooked. It is easy to understand that after the work control module finishes cooking, the fourth flag information needs to be cleared.

The fifth mark information written by the work control module is used for representing: under the condition that the household electrical appliances are the broken wall machine, the type of the cup body that the broken wall machine bore (not putting cup, drinking cup, or dry grinding cup), it is easy to understand, and the sensor on the broken wall machine can be utilized to the work control module, detects the type of the cup body that the broken wall machine bore.

And the sixth mark information, the reserved mark information, is used for writing in other information meeting the actual service requirements.

As shown in fig. 4, the data area is divided into a first data area, a second data area, and a third data area. Meanwhile, the entire data area may be a custom data area. In fig. 4, the first flag information is denoted as F0, the second flag information is denoted as F1, the third flag information is denoted as F2, and the fourth flag information is denoted as F3.

In addition, the data area may also include a standard data area and a custom data area, and the custom data area further includes a first data area, a second data area, and a third data area. The standard data area adopts a standard data exchange format defined by an NFC protocol, the standard data area comprises a header data area and a Record (Record) data area, and the Record data area comprises a plurality of NFC records.

In some embodiments, the step of the product application writing the second interactive data to the second data area comprises:

reading the second flag information from the third data area, and writing the second interactive data to the second data area in the case where the first specified condition is satisfied; the first specified condition includes: the second flag information indicates a negative determination result. Correspondingly, after the product application writes the second interactive data into the second data area, the second flag information in the third data area is set to represent a positive judgment result.

In case the product built-in module has read the second interactive data that was written into the second data area last time, the user is allowed to write new second interactive data into the second data area again. In order to fulfill this need, technical means are utilized: the user side needs to write new second interactive data into the second data area only when it is determined that the second flag information indicates that second interactive data which are not read by the product built-in module do not exist in the second data area, and meanwhile, after the user side writes the second interactive data into the second data area, the user side needs to modify the second identification information to indicate that the second interactive data which are not read by the product built-in module exist in the second data area.

In some embodiments, the product application stops writing the second interactive data to the second data area if it is determined that the first specified condition is not satisfied.

In case that the product built-in module has not read the second interactive data which was written into the second data area last time, the user may be denied to write new second interactive data into the second data area again.

In some embodiments, the product application notifies the user that writing the second interactive data fails and/or notifies the user that the home appliance is in a power-off state if it is determined that the first specified condition is not satisfied.

Generally speaking, if the second interactive data written into the second data area at the last time is not read by the product built-in module in time, it indicates that the household appliance is in the power-off state, and in this case, the user can be reminded that the writing fails at this time, or the user is reminded that the household appliance is in the power-off state.

It should be noted that, generally, the NFC module is passive (does not need a power supply maintaining function), which means that even if the household electrical appliance is in a power-off state, data reading and writing of the NFC module of the household electrical appliance by the user side are not affected.

In some embodiments, the second interaction data comprises: a control instruction; the product built-in module includes: and the work control module of the household appliance is used for controlling the household appliance to realize the corresponding work flow according to the control instruction. Correspondingly, the product application reads the third mark information from the third data area; the first specified condition further includes: the third mark information indicates that the working state of the household appliance is standby.

The household appliance is in a standby state, which means that the household appliance is not powered off, has no fault and is not working, so that the working control module of the household appliance can execute the control instruction in time. If the household appliance is not in the standby state, the work control module of the household appliance cannot execute the control command in time, so that the user can be refused to write the control command into the second data area.

In some embodiments, the home appliance is in a powered on state; the product built-in module reads second interactive data from the second data area, and the method comprises the following steps: the product built-in module reads second mark information from the third data area after monitoring that the communication connection between the NFC module of the user equipment and the NFC module of the household appliance is disconnected, and reads second interactive data from the second data area under the condition that a second specified condition is met; the second specified condition includes: the second flag information indicates a positive judgment result; and after reading the second interactive data, the work control module sets the second mark information in the third data area to represent a negative judgment result.

If the household appliance is in the power-on state, the product built-in module can monitor that the communication connection between the NFC module of the user equipment and the NFC module of the household appliance is disconnected (indicating that the user side completes writing in the second interactive data), and timely reads the second interactive data from the second data area when the connection disconnection is monitored. After the product built-in module reads the second interactive data, the second flag information in the third data area needs to be modified to indicate that the second interactive data which is not read by the product built-in module does not exist in the second data area.

In some embodiments, when the communication connection between the NFC module of the user equipment and the NFC module of the home appliance is disconnected, the home appliance is in a power-off state. The product built-in module reads second interactive data from the second data area, and the method comprises the following steps: the product built-in module reads the second mark information from the third data area after being in the power-on state again, and reads the second interactive data from the second data area under the condition that a second specified condition is met; the second specified condition includes: the second flag information indicates a positive judgment result; and after reading the second interactive data, the work control module sets the second flag information in the third data area to represent a negative judgment result.

If the communication connection between the NFC module of the user equipment and the NFC module of the household appliance product is disconnected, the household appliance product is in a power-off state, and then the built-in module of the product cannot monitor the connection disconnection in time, and cannot read second interaction data from the second data area in time.

If the household appliance is still in the power-off state after the user side writes the second interactive data into the second data area, the next time the user side needs to write new second interactive data into the second data area, the writing fails because the second flag information in the third data area indicates that the second interactive data (i.e., the second interactive data written at the last time on the user side) which is not read by the product built-in module exists in the second data area.

After the household appliance is powered on, the second mark information in the third data area can be read immediately, whether second interactive data which needs to be read from the second data area exists or not is judged, if the second interactive data exists, the second interactive data can be read immediately, and meanwhile, the second mark information in the third data area is modified to indicate that the second interactive data which is not read by the product built-in module does not exist in the second data area.

Generally, an NFC-enabled device will default to supporting the NFC protocol and may identify NFC records in the NFC data area that have a common NFC data exchange format. If the device vendor defines other kinds of NFC data exchange formats, logic for identifying NFC records of the other kinds of NFC data exchange formats is also built into the operating system of the factory device.

In practical applications, some important service data (such as the number of times of using the main in-transit function) may need to be stored in the data area of the NFC module of the home appliance, and a manufacturer of the home appliance sometimes wants, in view of safety of the important service data, that an operating system (maintained by the manufacturer of the user equipment) of the user equipment is only readable and not writable for data in NFC without permission. In other words, the operating system of the user mobile device is required to write data, such as a user identifier, distribution network information provided by a user, a control instruction, and the like, into the NFC of the home appliance product under the condition that the operating system of the user mobile device cannot rewrite data in the NFC module of the home appliance product under a default condition and the operating system of the user mobile device is required by a manufacturer of the home appliance product.

Since the data exchange format used in the custom data area is not the NFC data exchange format specified by the NFC protocol, the operating system of the user device cannot recognize the data in the custom data area even if the operating system can read the data in the custom data through the NFC module of the user mobile device.

Correspondingly, for important service data in the custom data area, only software (a product service end system, product application, and a work control module in a household appliance) developed by a product manufacturer can be identified. Therefore, under the condition that the NFC module of the household appliance product has the custom data area, the user equipment needs to install the product application, after the product application is started, the product application identifies data in the custom data area read by the NFC module of the user mobile equipment, and in addition, the product application can call an operating system of the user equipment to write data into the custom data area.

In addition, the data area of the NFC module may include a standard data area in addition to the custom data area. In general, manufacturers of home appliances desire to implement that the home appliance side is readable and writable to the standard data area, and the product application side is not readable and writable to the standard data area. Therefore, the work control module of the home appliance needs to lock the data in the standard data area, and prevent the application side of the product from modifying the data in the standard data area. Specifically, the work control module may indicate whether the product application that reads the locking flag bit information has the right to modify the data in the standard data area by setting the locking flag bit information (indicating locking or unlocking) in the standard data area.
