The MAC address of the household appliance;

The URL of the control interface corresponding to the household appliance.

Among them, each household appliance has a unique product serial number, and the product serial number of the household appliance includes information such as the manufacturer of the household appliance, the type of the household appliance, and the model of the household appliance.

The MAC address of the household appliance, which is used for the unique network identifier of the communication connection of the server 5 .

The control interface URL corresponding to the home appliance, the storage address on the network cloud server of the home appliance control interface, and the control interface of each APP program corresponds to the unique control interface URL corresponding to the home appliance.

In this embodiment, a correspondence table between household appliances and NFC tag data as shown in FIG. 4 can be stored in the server 5. The contents of the correspondence table include: NFC tag ID, product serial number of household appliances, household appliances The MAC address of the home appliance, and the URL of the control interface corresponding to the home appliance. Obtain any item of data in the table shown in FIG. 4 and query through the server 3 to obtain all the information of the household appliance 1 .

In this embodiment, the NFC tag ID, the product serial number of the household appliance, and the MAC address of the household appliance are all unique. Therefore, a one-to-one correspondence is established between the NFC tag ID, the product serial number of the household appliance, and the MAC address of the household appliance. relationship, that is, by determining one of the pieces of information, other information about the household appliance can be queried from the correspondence table of the household appliance and the NFC tag data shown in FIG. 4 .

In this embodiment, the control interfaces of the same type of household appliances are the same, therefore, the web address of the control interface corresponding to one household appliance may correspond to multiple household appliances. As shown in Figure 4, the control interface URLs corresponding to the two household appliances whose network MAC addresses are BC-17-B8-B7-D1-76 and BC-17-B8-B7-D1-77 are both www.hanraylaw.com /A98/432.html, which indicates that the above two household appliances are of the same model.

Further, the smart terminal (smartphone 4 in FIG. 1 ) reads any information in the NFC tag ID, the product serial number of the household appliance, and the MAC address of the household appliance contained in the NFC tag, and by querying the information shown in FIG. 4 The corresponding relationship table of household appliances and NFC tag data can be obtained, and the control interface URL of the household appliances can be obtained.

In this embodiment, the data of the NFC tag 3 is written into the data storage area specified in the NFC tag 3 according to a specified data format. As an example, Figure 5 shows the data and storage area definitions for the NFC tag 3. The data storage format of the product serial number of the household appliance is ASCII format, the block address of the storage area of NFC tag 3 is 0x05, and the address range of the area within the block is 0x00 to 0x0D; the data storage format of the MAC address of the household appliance is hexadecimal format, the block address in the storage area of NFC tag 3 is 0x06, and the address range of the area within the block is 0x00 to 0x05; the storage format of tag attribute data is hexadecimal format, and the block address in the storage area of NFC tag 3 is 0x07, The address of the area within the block is 0x00.

It should be pointed out that although several examples of the data content, data format, and storage area stored in the NFC tag are listed here. However, those skilled in the art can understand that these examples should not constitute any limitation on the protection scope of the present invention. Under the premise of not changing the basic principle of the present invention, those skilled in the art can define the content such as the data format and storage area stored in the NFC tag according to the actual situation such as the product serial number length of the household appliance and the type of the NFC tag.

In a preferred embodiment, the working interface is jointly determined by NFC tag data and user identity information. That is to say, the APP operation involved in the present invention requires the user to log in to the APP in advance. After the user logs in, the smartphone 4 automatically records the user's login information, so that the user does not need to log in again for verification within a certain period of time, and the smartphone 4 reads the NFC tag. After 3, you can directly trigger APP2 to run. For a new user, the login operation can only be performed after registration. When a new user registers, the smart phone 4 transmits the user identity information to the server 5, and the server 5 establishes a personal household appliance usage file for the user. Commonly used login verification methods for APP include: username and password verification method, mobile phone verification code method, WeChat/Alipay authorization method, face recognition method, fingerprint recognition method, and shared login verification through joined family members, etc. The login verification method has been well known by most technical personnel, and will not be repeated here.

In a preferred embodiment, as shown in FIG. 6 , the user's household appliance usage profile data can be stored in the form of a table. The data content of the user's home appliance usage file generally includes: user ID, home appliance MAC address, use date, use time, working mode and other information. The user's household appliance usage file data table records the situation of each user's use of household appliances, such as which household appliance, usage time, and the working mode of the household appliance. Through the big data analysis of the server 5, the usage habits of each user on each household appliance can be obtained.

In a preferred embodiment, the working mode types of the washing machine 1 can be divided into three types: standard washing program, self-learning washing program and customized washing program. The standard washing program is the washing mode preset by the washing machine manufacturer, such as quick wash, mixed wash, pure cotton wash, etc. The self-learning washing program is a recommended working mode of the user on the household appliance obtained by the server after analyzing and learning according to the user's usage record data on the household appliance. The customized washing program is a washing program that the user sets and saves on the household appliance according to his personal preference. If the washing program set by the user is not saved, the washing program data will also be uploaded to the server 5 as the basic data of the self-learning washing program. That is to say, the working mode of the standard washing program has nothing to do with user information, and the self-learning washing program and the customized washing program are related to user identity information and are related to specific household appliances.

Continuing to read FIG. 6 , in this embodiment, the coding of the working mode can be composed of three parts: the working mode type, the working mode number and the user number. In the example of FIG. 6 , the working mode type consists of a single letter, A represents a standard washing program, B represents a self-learning washing program, and C represents a customized washing program. The working mode number consists of two digits, indicating the washing program in the corresponding working mode type. The user code is used to distinguish the special working modes of different users, and this item of the standard washing program can be vacant. For example: A-01 represents the quick wash in the standard washing program; A-02 represents the mixed wash in the standard washing program; B-01-N0001 represents the self-learning washing program numbered 01 by the user numbered N0001; C-01 -N0001 represents the customized washing program numbered 01 for the user numbered N0001; C-01-N0002 represents the customized washing program numbered 01 for the user numbered N0002.

In this embodiment, the working program interface may display the working modes of one or more home appliances. When only one working mode is displayed, the working mode can be from any one of the standard washing program, the self-learning washing program and the customized washing program. When multiple washing programs are displayed, the washing programs can be any number and combination of any form from standard washing programs, self-learning washing programs, and customized washing programs. For example, when three wash programs are displayed, all three wash programs are from a standard wash program; or two are from a standard wash program and one is from a custom wash program; or some other combination. The number of work modes displayed in the work program interface, APP2 preferably defaults to one; the user can also set and display multiple work modes according to personal preferences.

In this embodiment, the determination of the working mode is performed on the server 5, and the server 5 can set various rules for determining the working mode. For example, when only one work mode is displayed on the work program interface, the following rules can be set: rule 1, the work mode used last time by the user; rule 2, the most used work mode among the last 10 work modes used by the user, if there are multiple same work modes , use the one closest to the current time. Likewise, a determination rule when the working program interface of the home appliance displays multiple working modes can be set. The selection of the working mode can be either a default one of the server 5, or can be selected by the user in the APP2.

In this embodiment, when the user sets only one working mode to be displayed, the operating mode of the working mode, the default setting of APP2 is to delay automatic operation, during the delay time waiting, the user can cancel the displayed mode and re-select other Working mode; the default delay time of APP2 is 10 seconds, and the user can modify the delay time. In addition, the user can also cancel the delay automatic operation setting, and change it to run after clicking confirm. When the user sets to display multiple working modes, APP2 is usually set to run after clicking to confirm, and the user can select one of the displayed working modes, or re-select other working modes. If the user does not select after the waiting time, the default one of several displayed working modes can be directly executed.

It should be pointed out that although several examples of the data of the user's household appliance usage profile, the type of work mode, the code of the work mode, the determination of the work mode, and the number of work modes displayed are listed here. However, those skilled in the art can understand that these examples should not constitute any limitation on the protection scope of the present invention. Under the premise of not changing the basic principle of the present invention, those skilled in the art can design these data according to the actual situation.

As an example, the household appliance to be controlled is the washing machine 1 in the NFC household appliance system shown in FIG. 1 , the server 5 of the NFC household appliance system is a smart home server in the cloud, and both the washing machine 1 and the smart phone 4 have been connected to the local network. And the communication link between the local network and the smart home server in the cloud is smooth, the NFC tag 3 has been written with data and set on the washing machine 1 or other convenient location in the room for the user to operate, the NFC function of the smartphone 4 has been turned on, and the APP2 has been stored User's login information.

Next, referring to FIG. 7 , the main working method flow of NFC home appliance control includes:

Step S701: the smart terminal (the smart phone 4 in FIG. 1 ) approaches the NFC tag and reads the data of the NFC tag (the NFC tag 3 in FIG. 1 );

Step S702: the APP (APP2 in FIG. 1) background service program parses the NFC tag data;

Step S703: The APP connects to the smart home server (server 5 in FIG. 1 ) in the cloud through the smart terminal, and uploads the NFC tag data and user information to the server;

Step S704: The smart home server in the cloud establishes a connection between the home appliance (the washing machine 1 in FIG. 1 ) and the smart terminal through the Internet of Things module (the Internet of Things module 6 in FIG. 1 ) according to the MAC address of the home appliance in the NFC tag data. data channel;

Step S705: the APP accesses the website of the home appliance control interface in the NFC tag to obtain the control interface of the home appliance;

Step S706: The APP displays the working program interface of the household appliance according to the working mode determination result fed back by the smart home server in the cloud;

Step S707: run the working mode displayed on the working program interface after automatic running or delayed automatic running or after the user clicks OK;

Step S708: the IoT module receives the server command to control the work of the household appliance;

Step S709: The smart home server in the cloud records the usage data of the user's home appliances.

As the premise of step S706, after receiving the NFC tag data and the user information, the server can analyze and determine the working mode suitable for the user according to the MAC address of the household appliance in the NFC tag data, combined with the user information, and according to the preset rules. , and send the determined working mode to the APP.

In addition, it should be pointed out that steps S703, S705 and S706 are performed almost simultaneously. Specifically, when the APP uploads the NFC tag data and user information to the server, the APP can access the home appliance control interface URL in the NFC tag, and the server can almost change the working mode when receiving the NFC tag data and user information. Send it to the APP, so in practice, as long as the user brings the smartphone close to the NFC tag, the above operations are all completed in an instant, and almost no time delay is perceived.

Furthermore, in step S707, "automatic operation" refers to directly running the program without user confirmation after jumping to the working program interface, and "delayed automatic operation" refers to that although user confirmation is required but the user does not confirm it within the specified time Or choose, so the default program will be executed when the set duration is reached. "After the user clicks OK, run the working mode displayed on the working program interface" means that the user performs a confirmation operation within the specified time or selects a specific working mode, and executes accordingly. The operating mode confirmed or selected by the user.

In some embodiments, since the data content of the NFC tag 3 can be copied, that is to say, multiple NFC tags 3 can be written into the same information such as the product serial number, MAC address and corresponding control interface website address of the same household appliance. Therefore, in the same home application environment, multiple tags can be configured for one household appliance.

It should be pointed out that, for security reasons, only the NFC tag installed on the household appliance is usually allowed to control the household appliance to work automatically after reading it, and other remotely set NFC tags can only be used to view the working status and adjust the work. parameters and make the program pause or continue running. For example, when the user reads the NFC tag 3 installed on the washing machine 1, he often also checks whether there are children or pets in the washing machine drum, confirms that there is no foreign matter in the washing machine drum, and closes the washing machine door. , so the functions of multiple tags usually configured for a household appliance are different. The difference in tag functions can be distinguished by the data of the NFC tag 3 shown in FIG. 5 and the tag attributes in the storage area definition. It can be stipulated that when the attribute data of the tag is 0xAA, the tag can directly and automatically control the operation of household appliances through the smart terminal; when the attribute data of the tag is 0x00, it means that the automatic operation of household appliances cannot be controlled through the intelligent terminal, but the working status of the washing machine can be viewed in real time. And when the washing machine has started to work, the washing machine can be controlled to pause and continue to run.

As an example, multiple NFC tags 3 can be configured for the same washing machine 1, and one of them is usually set on the body of the washing machine 1, and the tag attribute data is 0xAA, for example, it is set under the handle cavity of the detergent dispenser box of the washing machine 1 11, the top surface 12 of the control knob of the washing machine 1, the rightmost side 13 of the control panel of the washing machine 1, and other NFC tags 3 can be set in other places in the room that are convenient for users to operate according to the actual situation, and the tag attribute data is 0x00, such as the coffee table, bedside table, etc., so that the remote control of the washing machine 1 is realized. As an example scenario, the user is preparing to do laundry, and the favorite ball game has started. At this time, the user can put the clothes into the washing machine 1 and close the door, touch the label on the washing machine with the smartphone, and immediately run back to the TV, the washing machine can be It runs automatically according to the washing method recommended by the server; if the user feels that the sound of the washing machine is affecting the game, he can touch the NFC tag configured on the coffee table with his smartphone to display the washing machine working program interface, and pause the washing machine through the smartphone working program interface. Work, and then use the smartphone to continue the washing machine work during the game break or garbage time, so that the laundry and watching the game are not delayed.

In other embodiments, the server 5 may be a smart home server of the home local network, that is, the server of the NFC home appliance system is deployed on the local network, and the server is not connected to the public network. In this case, the smart home server of the home local network needs to store the control interface of the washing machine 1, and establish in the server the “URL of the home appliance control interface stored by the NFC tag” and the “home appliances stored by the smart home server of the home local network” in the server. Control interface” mapping relationship.

In some cases, the smartphone 4 is connected to a telecommunication operator's network and has access to the Internet. The APP 2 installed on the smart phone 4 can interact with the smart home server in the cloud through the network of the telecom operator, and can interact with the washing machine 1 on the local network through the smart home server in the cloud. In this case, the smartphone 4 can also control the operation of the washing machine 1 and view the operating parameters of the washing machine 1 by reading the NFC tag 3 set on the washing machine 1 .

In other cases, the washing machine 1 can also directly access the network of the telecommunications operator through 4G, 5G and other modules, and perform data interaction with the smart home server in the cloud. In this case, the smartphone 4 can also control the operation of the washing machine 1 and view the operating parameters of the washing machine 1 by reading the NFC tag 3 provided on the washing machine 1 .

In some simple situations, the washing machine 1 and the smartphone 4 can communicate directly with the smartphone 4, the hotspot function is enabled on the smartphone 4, and the washing machine 1 and the smartphone 4 communicate directly through the Wi-Fi network; The smart home server in the cloud performs data interaction. In this case, the smartphone 4 can also control the operation of the washing machine 1 and view the operating parameters of the washing machine 1 by reading the NFC tag 3 provided on the washing machine 1 .
