Description

Method for connecting household electrical appliance to product server

Technical Field

The specification relates to the technical field of intelligent household appliances, in particular to a method for connecting a household appliance to a product server.

Background

Some home appliances on the market at present can be connected to a product server through a built-in Wi-Fi module. When a user uses a home electric appliance for the first time, the home electric appliance is usually required to be connected to a product service end through operation for use.

Specifically, a user generally triggers a home appliance to start distribution, and when the home appliance starts distribution, the built Wi-Fi module is switched from a Station mode of a terminal to an Access Point (AP) mode; and the Wi-Fi module receives the distribution network information transmitted by the user in the AP mode. After the distribution network is completed, the Wi-Fi module is required to be switched from the AP mode to the Station mode, and is accessed into the network according to the distribution network information in the Station mode, and then is connected to the product server according to the domain name of the product server.

However, a process from the start of network distribution to the connection of the home appliances to the product server requires a long time, and the user experience is poor.

Disclosure of Invention

Aiming at the technical problems, the specification provides the following technical scheme:

In a first aspect, a method for connecting a home appliance to a product server is provided, wherein the home appliance has an NFC module and a Wi-Fi module that are connected; the method comprises the following steps:

The method comprises the steps that a product application on a user mobile device obtains network allocation information of a network which is accessed by the user mobile device at present, and obtains an IP address which is resolved based on a domain name of a product server;

The product application calls an NFC module of the user mobile device, and writes the acquired distribution network information and the IP address into the NFC module of the household appliance;

the Wi-Fi module of the household appliance performs the following steps in the state mode: and monitoring the level of an induction signal between the NFC module of the household electrical appliance and the NFC module of the user mobile device, and reading distribution network information and an IP address in the NFC module of the household electrical appliance when the change from low level to high level is monitored, so as to complete distribution network and connect to the product server.

In the technical scheme of the first aspect, a user uses a product application installed on the mobile device to perform network distribution on the household electrical appliance, so that after the household electrical appliance completes network distribution, the household electrical appliance can access a network and then be connected to a product server.

Specifically, the NFC module of the home appliance is connected to the Wi-Fi module, which means that the Wi-Fi module can read and write a data area of the NFC module of the home appliance, and can also monitor an induction signal between the NFC module of the home appliance and the NFC modules of other devices. On the user side, when the user needs to connect the home appliance to the product server, the user can open the product application installed on the mobile device. The product application obtains the network distribution information of the network currently accessed by the mobile equipment and the IP address resolved based on the domain name of the product server. The product application calls the NFC module of the user mobile device, establishes NFC connection with the NFC module on the household appliance, and writes the distribution network information into the NFC module of the household appliance by utilizing the NFC connection. And the product application also writes the IP address resolved based on the domain name of the product server into the NFC module of the household appliance by utilizing NFC connection.

On the product side, the Wi-Fi module of the home appliance does not need to be switched from the Station mode to the AP mode in the whole process, but can be kept in the Station mode. The Wi-Fi module of the home appliance may acquire the distribution network information and the IP address of the product server in the NFC module of the home appliance when it is monitored that the level of the sensing signal between the NFC module of the user mobile device and the NFC module of the home appliance changes from low level to high level (this may indicate that the NFC module of the user mobile device is leaving the field, and may also indicate that the NFC module of the user mobile device has written the distribution network information and the IP address into the NFC module of the home appliance), and complete distribution network and connect to the product server.

According to the technical scheme of the first aspect, the time required from the start of the network distribution of the user to the connection of the household electrical product to the product server can be shortened, and the user experience is improved.

Firstly, the network distribution information of the network to which the user mobile equipment is currently connected is transmitted to the household electrical appliance through NFC connection, and because the NFC technology has near field (namely the user mobile equipment and the household electrical appliance are close enough to establish NFC connection), the network distribution information transmitted to the household electrical appliance is the network distribution information of the same network environment, and the network distribution information adopted by the Wi-Fi module of the household electrical appliance for network distribution is the network distribution information of the network environment in which the household electrical appliance is located. This in turn means that the Wi-Fi module of the home appliance does not need to switch to the AP mode to check the distribution network information when distributing the network (the check can detect a hotspot of the network to which the distribution network information corresponds). The Wi-Fi module needs a long time (generally 2-3 seconds) to perform mode switching (whether from Station mode to AP mode or from AP mode to Station mode), and if mode switching is omitted, the time required from the start of network distribution of a user to the connection of a home product to a product server can be shortened.

Secondly, in the process that the Wi-Fi module of the household appliance is connected to the product service end according to the domain name, the step (usually 1-2 seconds) that the domain name resolution service end resolves the domain name and returns the domain name to the IP address of the Wi-Fi module of the household appliance is involved, and the IP address after the domain name resolution of the product service end is directly transmitted to the household appliance, so that the Wi-Fi module of the household appliance can be directly connected to the product service end according to the IP address of the product service end after the network distribution is completed, and the time required from a user to the process that the household appliance is connected to the product service end after the network distribution is started can be further shortened.

Again, the Wi-Fi module of the home appliance may read information from the NFC module of the home appliance in time when it is monitored that the NFC module of the user mobile device may be off-line (at this time, the NFC module of the user mobile device may just complete writing of information), instead of waiting for a long time to read information from the NFC module, which may further shorten the time required from when the user starts the network distribution to when the home appliance is connected to the product server.

Further: NFC module and Wi-Fi module of household electrical appliances integrate in same circuit board.

The NFC module and the Wi-Fi module integrated on the same circuit board are more reliable in communication, communication delay is lower, and time required from the process of starting network distribution to the process of connecting the household electrical product to the product server can be further shortened.

Further: the distribution network information comprises: wireless network identification and wireless network password.

The configuration information of the wireless network may be a wireless network identification (e.g., SSID of a router) and a wireless network password.

Further: the product application obtains the distribution network information of the network accessed by the product application, and the distribution network information comprises:

The product application obtains the wireless network identification of the network currently accessed by the user mobile equipment from the operating system of the user mobile equipment, and obtains the wireless network password input by the user.

In practical applications, the product application may not have the right to acquire the wireless network password from the operating system, in which case the wireless network password needs to be input into the interface of the product application.

Further: the product application obtains the IP address resolved based on the domain name of the product server, comprising:

and the product application sends the domain name of the product server to a domain name resolution server and acquires the IP address returned by the domain name resolution server.

When a user operates the product application, the product application can send the domain name of the product server to the domain name resolution server in the background and obtain the IP address returned by the domain name resolution server, the process is not perceived by the user, the time required from the process of starting the network distribution to the process of connecting the household product to the product server is not accumulated, and the user experience is improved.

Further: the data area of the NFC module comprises a standard data area and a custom data area, wherein the standard data area is configured to use a data exchange format defined by an NFC protocol, and the custom data area is configured to use a data exchange format custom by a manufacturer of the household electrical appliance;

The product application calls the NFC module of the user mobile device, writes the acquired distribution network information and the IP address into the NFC module of the home appliance product, and comprises the following steps:

The product application processes the acquired configuration network information and the format of the IP address into the self-defined data exchange format; and calling the NFC module of the user mobile equipment, and writing the network allocation information with the customized data exchange format and the IP address into a customized data area of the NFC module of the household appliance.

The operating system of the user mobile device cannot analyze the data exchange format customized by the manufacturer of the home appliance, so that the operating system of the user mobile device (controlled by the manufacturer of the user mobile device) cannot modify the data in the customized data area even if the operating system has the write permission to the customized data area in the NFC module of the home appliance. The operating system of the user mobile device can only modify the data in the custom data according to the instructions of the product application, and the operating system cannot analyze the business meaning of the data modified by the instructions of the product application. Thus, the data security of the manufacturer of the household electrical appliance can be ensured.

Further: the Wi-Fi module of the home appliance further performs the steps of:

when the change from high level to low level is monitored for the first time, setting a writing control mark in an NFC module of the household appliance as a first mark, and setting the writing control mark in the NFC module of the household appliance as a second mark from the first mark after a specified time length;

the product application writes the acquired distribution network information and the IP address into the NFC module of the home appliance product, and the product application comprises the following components:

When the product application meets the writing condition, writing the acquired distribution network information and the IP address into an NFC module of the household appliance; wherein the writing conditions include: the write control flag read from the NFC module of the home appliance is set to a second flag.

In order to prevent the problem of failure in writing distribution network information caused by unstable level of an induction signal after the NFC module of some user mobile equipment establishes connection with NFC of a household appliance, the following technical means are adopted: the Wi-Fi module at the home appliance side can modify the writing control mark in the NFC module, and when the NFC module of the user mobile device is monitored to enter the field (when the induction signal is monitored to change from high level to low level for the first time), the writing control mark is set as a first mark, so that when the first mark is read by the product application, information writing is not carried out on the NFC module of the home appliance; after waiting for a specified duration (the level of the sensing signal starts to be stable), the Wi-Fi module modifies the writing control mark into a second mark, so that when the second mark is read by the product application, the NFC module of the household appliance starts to write information. Therefore, the time delay of the information writing of the distribution network for the product application can be realized, the information writing is executed when the level of the sensing signal is relatively stable, the success of writing is ensured as much as possible, the disturbance of writing failure to a user is avoided, the phenomenon that the user takes the mobile device away from the household electric product and gets close again due to the writing failure is avoided, and the time required for the process from the user to start the distribution network to connect the household electric product to the product service end is shortened in fact.

Further: when the change from low level to high level is monitored, the network allocation information and the IP address in the NFC module of the household electrical appliance are read, and the method comprises the following steps:

After a write control flag in an NFC module of the home appliance is set to a second flag from a first flag, when the change from low level to high level is monitored, the distribution network information and the IP address in the NFC module of the home appliance are read.

After the product application is ensured to successfully write information into the NFC module of the household electrical appliance, the off-site time (the level of the sensing signal changes from low level to high level) of the NFC module of the user equipment is monitored again, so that the required distribution network information and IP address can be read from the NFC module of the household electrical appliance, the success rate of reading the distribution network information and the IP address is improved, and the time required for connecting the distribution network from a user to the household electrical appliance to the product service end is shortened in fact.

Further: after the home appliance is connected to the product server, the method further comprises: and the product application receives a connection success notification sent by the product server.

The product server can inform the user that the household appliance is successfully connected to the product server by sending a connection success notification to the product application, so that user experience is improved.

In a second aspect, another method for connecting a home appliance to a product server is provided, the home appliance has a control module, an NFC module and a Wi-Fi module, and the NFC module and the Wi-Fi module are respectively connected with the control module; the method comprises the following steps:

The control module monitors the level of an induction signal between the NFC module of the household appliance and the NFC module of the user mobile device, and when the change from low level to high level is monitored, the control module reads the distribution network information and the IP address in the NFC module of the household appliance and sends the distribution network information and the IP address to the Wi-Fi module of the household appliance;

and the Wi-Fi module of the household appliance completes network distribution and is connected to the product server under the condition of being placed in a Station mode.

In the technical scheme of the second aspect, the user uses the product application installed on the mobile device to perform network distribution on the household electrical appliance, so that after the household electrical appliance completes network distribution, the household electrical appliance can access to the network and then be connected to the product service end.

Specifically, the NFC module of the home appliance is connected to the control module, which means that the control module can read and write the data area of the NFC module of the home appliance, and can also monitor the sensing signal between the NFC module of the home appliance and the NFC modules of other devices. The Wi-Fi module of the home appliance is also connected to the control module, which means that the control module can transfer information in the NFC module of the home appliance to the Wi-Fi module.

On the user side, when the user needs to connect the home appliance to the product server, the user can open the product application installed on the mobile device. The product application obtains the network distribution information of the network currently accessed by the mobile equipment and the IP address resolved based on the domain name of the product server. The product application calls the NFC module of the user mobile device, establishes NFC connection with the NFC module on the household appliance, and writes the distribution network information into the NFC module of the household appliance by utilizing the NFC connection. And the product application also writes the IP address resolved based on the domain name of the product server into the NFC module of the household appliance by utilizing NFC connection.

On the product side, the Wi-Fi module of the home appliance does not need to be switched from the Station mode to the AP mode in the whole process, but can be kept in the Station mode. The control module of the home appliance may acquire the network distribution information and the IP address of the product server in the NFC module of the home appliance and send the network distribution information and the IP address of the product server to the Wi-Fi module when the level of the sensing signal between the NFC module of the user mobile device and the NFC module of the home appliance changes from low level to high level (this may indicate that the NFC module of the user mobile device is leaving the field, that is, may indicate that the NFC module of the user mobile device has written the network distribution information and the IP address into the NFC module of the home appliance), so that the Wi-Fi module completes the network distribution and is connected to the product server.

According to the technical scheme of the second aspect, the time required from the start of the network distribution of the user to the connection of the household electrical product to the product server can be shortened, and the user experience is improved.

Again, the control module of the home appliance may read information from the NFC module of the home appliance in time and transmit the information to the Wi-Fi module when it is monitored that the NFC module of the user mobile device may be off-line (at this time, the NFC module of the user mobile device may just complete information writing), instead of waiting for a long time to read information from the NFC module, which may further shorten the time required from when the user starts the process of network distribution to when the home appliance is connected to the product server.

Further: further comprises:

When the control module detects the change from high level to low level for the first time, the writing control mark in the NFC module of the household appliance is set as a first mark, and after a specified time period passes, the writing control mark in the NFC module of the household appliance is set as a second mark from the first mark;

In order to prevent the problem of failure in writing distribution network information caused by unstable level of an induction signal after the NFC module of some user mobile equipment establishes connection with NFC of a household appliance, the following technical means are adopted: the control module at the home appliance side can modify the writing control mark in the NFC module, and when the NFC module of the user mobile device is monitored to enter the field (when the induction signal is monitored to change from high level to low level for the first time), the writing control mark is set as a first mark, so that when the first mark is read by the product application, information writing is not carried out on the NFC module of the home appliance temporarily; after waiting for a specified time period (the level of the sensing signal starts to be stable), the control module modifies the writing control mark into a second mark, so that when the second mark is read by the product application, the NFC module of the household appliance starts to write information. Therefore, the time delay of the information writing of the distribution network for the product application can be realized, the information writing is executed when the level of the sensing signal is relatively stable, the success of writing is ensured as much as possible, the disturbance of writing failure to a user is avoided, the phenomenon that the user takes the mobile device away from the household electric product and gets close again due to the writing failure is avoided, and the time required for the process from the user to start the distribution network to connect the household electric product to the product service end is shortened in fact.

Detailed Description

In the present description, a number of different conceptual solutions are described. In each technical solution of the concept, there are one or more embodiments, and the technical solutions of different concepts may be combined with each other to form further embodiments. After reading the present specification, those skilled in the art may combine the technical solutions of different concepts to obtain new technical solutions, and these new technical solutions should also fall within the scope of the present specification.

The technical solutions of these different concepts are described in turn below. Some of these concepts may be represented by a number of different concepts, and for these concepts, an explanation is given here when they first appear, and a description is not repeated hereinafter.

The household appliance product described herein generally refers to an electric appliance product applied to various applications in a home environment, and specifically may be a cooking appliance having a certain cooking function, such as an electric pressure cooker, an electric frying pan, and the like. In addition, the cooking appliance can also be a multifunctional cooking appliance with various cooking functions.

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

Some home appliances on the market at present can be connected to a product server through a built-in Wi-Fi module. When a user uses a home appliance for the first time, the home appliance is usually required to be connected to a product service end through operation, and the specific process is as follows: and providing the distribution network information to a Wi-Fi module of the household appliance, and enabling the Wi-Fi module to access a network according to the distribution network information and be connected to a product server through the network.

The distribution network information described herein generally refers to authentication information for connecting a device having a Wi-Fi module to a wireless network. The configuration information of the wireless network is typically a wireless network identification (e.g., SSID of a router) and a wireless network password.

As shown in fig. 1, in the current network configuration manner, when a user needs to configure a home appliance, firstly, a Wi-Fi module of the home appliance is switched from a factory default Station mode to an AP mode, and when the home appliance is in the AP mode, the user can search for a hotspot of the Wi-Fi module of the home appliance by using his mobile device, for example, a mobile phone, and then connect his mobile device to the hotspot of the Wi-Fi module of the home appliance. Therefore, the Wi-Fi module of the home appliance is equivalent to the fact that an information transmission channel is established between the user mobile device and the Wi-Fi module of the home appliance, and the user mobile device can transmit the distribution network information to the Wi-Fi module of the home appliance.

With continued reference to fig. 1, after the Wi-Fi module receives the distribution network information, in order to ensure that the received distribution network information is the distribution network information corresponding to the hot spot of the router existing in the surrounding environment, the distribution network information needs to be kept in the AP mode, that is, a hot spot identification list existing in the surrounding environment is detected, whether the wireless network identification contained in the received distribution network information is in the hot spot list is judged, if so, the Wi-Fi module can be switched to the Station mode again, the Wi-Fi module can be used as a Station, and is connected to the router according to the distribution network information, if not, the distribution network fails.

With continued reference to fig. 1, after the Wi-Fi module of the home appliance is connected to the router, the router may assign an intranet IP address to the home appliance, and the home appliance may be connected to an external network through the router using the assigned intranet IP address. Typically, the home appliance is connected to the external network for communication with the product server of the home appliance, so as to upload some data (such as a product usage record) on the home appliance to the product server, and receive some data (such as a control command) issued by the product server.

In the above process, the user needs to trigger the home appliance to start the AP mode, so that the network configuration information can be transmitted to the home appliance, and after the transmission is completed, the Wi-Fi module of the home appliance needs to be restarted and switched from the AP mode to the Station mode, so that the network configuration information can be accessed to the network. In the whole process, firstly, a user is required to manually switch a Wi-Fi module of a household appliance from a Station mode to an AP mode, then, after the Wi-Fi module of the household appliance acquires the network distribution information, the mode is switched once again (the mode is switched back to the Station from the AP mode), a certain time is consumed, and the time for waiting for the completion of the network distribution is long for the user. In addition, in the above process, the user often needs to operate his mobile device to temporarily disconnect from the router hotspot, and temporarily connect to the hotspot of the Wi-Fi module of the home appliance (so as to transmit the network allocation information), which is also troublesome for the user.

In addition, wi-Fi modules of home appliances are typically connected to a product server according to the domain name of the product server after accessing the network. In the process that the Wi-Fi module of the household appliance is connected to the product server according to the domain name, the step that the domain name resolution server resolves the domain name and returns the domain name to the IP address of the Wi-Fi module of the household appliance is involved, so that a certain time is consumed, and the user experience is poor.

In order to solve the technical problems, the specification provides a method for connecting a home appliance product to a product server.

The user uses the product application installed on the mobile equipment to distribute the network to the household appliances, so that the household appliances can be connected to the network after completing the network distribution and then connected to the product server.

Therefore, the time required from the start of the network distribution of the user to the connection of the household electrical product to the product server can be shortened, and the user experience is improved.

Fig. 2 is a flowchart of a method for connecting a home appliance to a product server according to an embodiment of the present disclosure, including the following steps:

S200: and the product application on the user mobile equipment acquires the network distribution information of the network which is accessed by the user mobile equipment currently, and acquires the IP address which is analyzed based on the domain name of the product server.

The home appliance in the method shown in fig. 2 may have an NFC module and a Wi-Fi module connected. The NFC module and the Wi-Fi module are usually connected through an interface, and specifically may be connected through an asynchronous transceiver (Universal Asynchronous Receiver/Transmitter, UART) serial port. Further, the home appliance product may further have a control module, and the NFC module and the Wi-Fi module are connected to the control module through interfaces, respectively.

In some embodiments, the NFC module and the Wi-Fi module of the home appliance are integrated on the same circuit board, and may be regarded as an integrated module. The NFC module and the Wi-Fi module integrated on the same circuit board are more reliable in communication, communication delay is lower, and time required from the process of starting network distribution to the process of connecting the household electrical product to the product server can be further shortened. If the household appliance also has a control module, the control module can be connected with the integrated module through an interface.

The user mobile device applied in the embodiments provided in the present specification needs to have an NFC module. The NFC module of the user is typically controlled by the operating system of the user's mobile device. The user brings the user mobile device close to the NFC induction area of the home appliance (namely, the NFC chip in the home appliance can induce the area), and the NFC module of the user mobile device can be triggered to establish NFC connection with the NFC chip of the home appliance. After the NFC connection is established, the operating system of the user mobile device can control the NFC module of the user mobile device to serve as a card reader to read and write data in the data area of the NFC chip of the household appliance.

It should be noted that, after the NFC connection is established, the operating system of the user mobile device generally reads all data in the data area of the NFC chip of the home appliance first, and whether to write data into the NFC chip later depends on whether the operating system executes the preset writing logic or whether the operating system receives the writing instruction sent by a certain installed application.

The product application described herein refers to an application developed by a manufacturer of a home appliance and used for providing services related to the home appliance to a user on a mobile device side of the user. The product application is typically installed in the operating system of the user's mobile device (described as the application being installed on the user's mobile device, which is also unambiguous). The application may be a client program (e.g., APP installed on a cell phone) or a light application (e.g., web application, android application, etc.). A lightweight application may be understood as a lightweight program that does not require a download client.

The product server refers to a server maintained by a manufacturer of the home appliance. In one aspect, the product application may interact with the product server through a network, for example, after the user operates the mobile device to start the product application, the product application may log into the product server through the product application, where the product application is equivalent to a binding relationship of a user identifier of the user. On the other hand, under the condition that the household electrical appliance is connected to the network, the product service end can interact with the household electrical appliance, and the product service end can monitor the running condition of the household electrical appliance by acquiring the running parameters uploaded by the household electrical appliance, and can also issue a control instruction to the household electrical appliance to control the household electrical appliance to execute corresponding operation.

The product server may be a server or a cluster of servers. And the product service end can be functionally divided into a service end for monitoring the running state of the product and a service end of a service layer. For example, the server for monitoring the operation state of the product may be an M2M platform, which needs to keep a long connection with the home appliance, and the home appliance reports the state change of the home appliance to the M2M platform. The service end of the service layer can be an IOT platform, and is in communication with the home appliances through short connection, and is responsible for account management, account binding, instruction issuing, push message issuing and the like.

In some embodiments, the user may manually open a product application installed in the operating system of the user's mobile device. Specifically, if the user mobile device installs a product client program, the user typically manually opens the product client program. In the case of a product application not installed, the user may choose to manually download and install the product client program, or to manually open the product light application.

After the product application is started, whether the user mobile equipment is accessed to a network through a Wi-Fi module of the user mobile equipment needs to be judged. Specifically, the product application may determine whether the Wi-Fi module of the user mobile device is activated, whether the Wi-Fi module of the user mobile device is connected to a router, and whether the router has access to the internet.

In some embodiments, after the product application is started, whether the Wi-Fi module of the user mobile device is started or not needs to be judged, whether the Wi-Fi module of the user mobile device is connected to the router or not needs to be judged, and if yes, the network capability of the user mobile device is used for requesting to be connected to the product server. If the product application is successfully connected to the product server, the router connected with the user mobile equipment is indicated to be accessed to the Internet, and the network distribution information used by the user mobile equipment can be obtained under the condition that the user mobile equipment is determined to be accessed to the network through the Wi-Fi module of the user mobile equipment.

If the product application detects that the user mobile device is connected to the network through the carrier's base station, the product application may prompt the user to connect the user mobile device to the router.

In some embodiments, the product application may present a list of models of home appliances to the user, from which the user may select the model of the home appliance currently desired to be networked. In other embodiments, the user may input to the product application the model of the home appliance currently desired to be networked.

The product application can judge whether the corresponding household appliance has an NFC module according to the type of the household appliance specified by the user, which means whether the user can utilize an NFC approach to carry out network distribution on the household appliance. If the product application determines that the home appliance has the NFC module, the user can be prompted to allocate the network by approaching the sensing area of the NFC module of the user mobile device to the sensing area of the NFC module of the home appliance.

In one or more embodiments, the product application may obtain, from the operating system, a wireless network identifier of a wireless network to which the user mobile device is currently connected, receive a wireless network password input by a user, and use the obtained wireless network identifier and the received wireless network password as network configuration information.

In practical applications, the product application may not have the right to obtain the wireless network password from the operating system (e.g., iOS operating system), in which case the wireless network password needs to be entered into the interface of the product application.

In some embodiments, after the product application is started, the product application can communicate with the product server, and the IP address of the product server is directly obtained from the product server.

In other embodiments, after the product application is started, the domain name of the product server may be sent to the domain name resolution server, and the IP address returned by the domain name resolution server may be obtained. When a user operates the product application, the product application can send the domain name of the product server to the domain name resolution server in the background and obtain the IP address returned by the domain name resolution server, the process is not perceived by the user, the time required from the process of starting the network distribution to the process of connecting the household product to the product server is not accumulated, and the user experience is improved.

S202: and the product application calls the NFC module of the user mobile equipment and writes the acquired distribution network information and the IP address into a data area of the NFC module of the household appliance.

The user may approach the sensing area of the NFC module of the user mobile device to the sensing area of the NFC module of the home appliance, so as to establish NFC connection between the NFC module of the user mobile device and the NFC module of the home appliance. The product application can read information such as the device ID, the MAC address and the Wi-Fi module of the home appliance from the data area of the NFC module of the home appliance through NFC connection.

The product application can verify the legitimacy of the home appliance according to the device ID, the MAC address and the like of the home appliance, and if the legitimacy verification is passed and the Wi-Fi module of the home appliance is determined not to be connected to a network, the network distribution information and the IP address are written into the data area of the NFC module of the home appliance.

The product application invokes the NFC module of the user's mobile device, in effect by sending instructions to the operating system of the user's mobile device.

S204: the Wi-Fi module of the home appliance performs in the state mode: and monitoring the level of an induction signal between the NFC module of the household electrical appliance and the NFC module of the user mobile device, and reading distribution network information and an IP address in the NFC module of the household electrical appliance when the change from low level to high level is monitored.

S206: and the Wi-Fi module of the household appliance completes the distribution network and is connected to the product service end.

When the home appliance leaves the factory, the Wi-Fi module of the home appliance is generally set in a Station mode by default. In the method shown in fig. 2, the Wi-Fi module of the home appliance may be always placed in the Station mode.

Through the method shown in fig. 2, firstly, the network allocation information of the network to which the user mobile device is currently connected is transmitted to the home appliance through the NFC connection, and because the NFC technology has near-field property (that is, the distance between the user mobile device and the home appliance is sufficiently close to establish the NFC connection), this means that the user mobile device and the home appliance are in the same network environment, the network allocation information transmitted to the home appliance is the network allocation information of the same network environment, and the network allocation information adopted by the Wi-Fi module of the home appliance for network allocation is the network allocation information of the network environment in which the home appliance is located. This in turn means that the Wi-Fi module of the home appliance does not need to switch to the AP mode to check the distribution network information when distributing the network (the check can detect a hotspot of the network to which the distribution network information corresponds). The Wi-Fi module needs a long time (generally 2-3 seconds) to perform mode switching (whether from Station mode to AP mode or from AP mode to Station mode), and if mode switching is omitted, the time required from the start of network distribution of a user to the connection of a home product to a product server can be shortened.

In addition, in practical applications, NFC of the home appliance is usually in a card mode. NFC of the home appliance may establish an NFC connection with any user mobile device having an NFC module. The authority corresponding to NFC of the home appliance is generally set so that the home appliance side can read and write data.

In some embodiments, if data security in NFC of the home appliance is not considered, the authority corresponding to NFC of the home appliance may also be generally set to be readable and writable on the user mobile device side (on the software level, an operating system of the user mobile device). The user identification may be written by any of the user mobile devices into the NFC data area of the home device. In this case, the product application may not be installed on the user mobile device, and any user mobile device may be able to obtain the user identification of the user holding the user mobile device.

It should be noted that the existing NFC data area generally includes several NFC records, which are data structures agreed by the NFC protocol, and the NFC records use the NFC data exchange format, i.e. NDEF. The existing NFC protocol specifies several common NFC data exchange formats (e.g. URL, picture) and also allows device manufacturers to define other kinds of NFC data exchange formats.

Generally, devices with NFC function will support the NFC protocol by default, and can identify NFC records with a universal NFC data exchange format in the NFC data area. If the device manufacturer 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.

However, in practical applications, some important service data may need to be stored in NFC of an electric home appliance, and in view of the security of the important service data, manufacturers of the electric home appliance sometimes want an operating system (maintained by the manufacturers of the user mobile device) of the user mobile device to be only readable and not writable to the data in NFC without being allowed. In other words, the operating system of the user mobile device is required to write data, such as a user identifier and network allocation information provided by a user, into the NFC of the home appliance when the operating system of the user mobile device is required by the home appliance manufacturer.

Therefore, a section of data area which cannot be identified by the operating system of the user mobile device can be added in the NFC data area of the home appliance, and for convenience of description, the added data area is called a (home appliance manufacturer) custom data area, and the custom data area uses a non-NFC data exchange format (the data exchange format agreed by the home appliance manufacturer in a private protocol can also be a private data exchange format). In addition, the data area except the custom data area in the NFC data area of the home appliance is referred to as a standard data area, and as described above, the standard data area includes at least one NFC record.

Meanwhile, the standard data area is set to be read only by the operating system of the mobile equipment of the user and not written; the set custom data field may be read and written by the operating system of the user's mobile device. Because the data exchange format used by the custom data area is not the NFC data exchange format specified by the NFC protocol, the operating system of the user mobile device cannot identify the data in the custom data area even if the data in the custom data can be read through the NFC module of the user mobile device.

Accordingly, only software developed by a product manufacturer (firmware in a product server system, a product application and a household appliance) can be identified for important business data in the custom data area. Therefore, in the case that the NFC of the home appliance has a custom data area, the user mobile device needs to install the product application, and after the product application is started, the product application identifies the data in the custom data area read by the NFC module of the user mobile device, and in addition, the product application may instruct the operating system of the user to move to write the data in the custom data area.

Thus, through the above series of technical settings, the user mobile device needs to write the data in the product NFC, uniformly writing the custom data area. The method and the device realize that the operating system of the user mobile equipment can not rewrite data in NFC of the household appliance under the default condition, and can write the data into the NFC of the household appliance under the control of the installed product application.

In some embodiments, the data area of the NFC module includes a standard data area configured to use a data exchange format defined by the NFC protocol and a custom data area configured to use a data exchange format custom by a manufacturer of the home product.

In this way, the product application can process the acquired configuration network information and the format of the IP address into the customized data exchange format, then call the NFC module of the user mobile device, and write the configuration network information and the IP address with the customized data exchange format into the customized data area of the NFC module of the home appliance product.

In addition, at present, the specifications of NFC modules of various user mobile devices in the market are different, and after the NFC connection is established between the mobile device en of some specifications of NFC modules and the home appliance, the fluctuation condition of the level of the sensing signal is different. On the other hand, if the mobile device side wants to write information into the NFC of the home appliance, writing is needed under the condition that the sensing signal is stable, otherwise, writing is easy to fail, the user is disturbed, the user has to take the mobile device off the NFC sensing area of the home appliance, and then re-try to establish the NFC connection.

This means that if the mobile device starts writing information to the NFC of the product soon after the NFC connection is established, the level of the sense signal may not be stable at this time, and writing failure is easy.

Fig. 3 is a schematic diagram of a change of a sensing signal level of NFC modules with different specifications provided in the present specification. As shown in fig. 3, when the NFC module of the apple mobile phone enters the field (NFC connection is established with the product NFC), the level becomes stable for a longer time after being changed from high to low once, so that for the apple mobile phone, after the NFC connection is connected, the product application writes information into the product NFC, and the success rate is very high. For the other two android mobile phones, a fluctuation period with a level repeatedly changed from high to low is experienced from the beginning of approach, and then the android mobile phones are stable, and particularly for the last android mobile phone, after NFC connection is connected, information is written into the product NFC by the product application, so that the success rate is low.

For this reason, in order to be compatible with the specifications of NFC modules of different mobile devices, a write control flag is deployed in NFC of the product, and at the same time, logic is deployed in the product application: the writing control mark is a first mark and cannot be written; the write control flag is a second flag, which can be written.

After the product side monitors the approach of the mobile device, the writing control mark is determined to be a first mark, so that the product application cannot execute information writing, and writing failure cannot occur. After the product side enters the field from the mobile equipment, the time delay is carried out, the time delay time length can be the first designated time length, and after the time delay, the writing control mark is modified into the second mark, so that the product application can read the second mark through the NFC module of the mobile equipment, and the writing of information to the NFC of the product is started.

The first appointed duration is N10 milliseconds, N is an integer, and N is more than or equal to 2 and less than or equal to 5. Experiments have shown that the NFC modules of various mobile devices, although of different specifications, typically have a time from approach to level plateau of between 20 milliseconds and 50 milliseconds, in many cases not exceeding 40 milliseconds.

Further, if the product side needs to acquire information written in the NFC by the product application, the network allocation information may be acquired from the NFC chip after a certain time from a time point when the writing control flag is modified to be the second flag. The waiting time may be an estimate of the length of time required for the product application to write the provisioning information to the NFC chip over the NFC connection.

In addition, the product side may acquire the network allocation information from the NFC chip when it is detected that the acquired sensing signal changes from a low level to a high level after modifying the write control flag to the second flag. That is, the product side can read the distribution network information when determining that the user mobile device leaves the field (the writing is proved to be completed).

In the method shown in fig. 2, in order to prevent the problem that writing of the distribution network information fails due to unstable induction signals after the NFC module of some user mobile devices establishes a connection with the NFC of the home appliance, the following technical means may be adopted:

the Wi-Fi module at the home appliance side can modify the writing control mark in the NFC module, and when the NFC module of the user mobile device is monitored to enter the field (when the induction signal is monitored to change from high level to low level for the first time), the writing control mark is set as a first mark, so that when the first mark is read by the product application, information writing is not carried out on the NFC module of the home appliance; after waiting for a specified duration (the level of the sensing signal starts to be stable), the Wi-Fi module modifies the writing control mark into a second mark, so that when the second mark is read by the product application, the NFC module of the household appliance starts to write information.

Therefore, the time delay of the information writing of the distribution network for the product application can be realized, the information writing is executed when the level of the sensing signal is relatively stable, the success of writing is ensured as much as possible, the disturbance of writing failure to a user is avoided, the phenomenon that the user takes the mobile device away from the household electric product and gets close again due to the writing failure is avoided, and the time required for the process from the user to start the distribution network to connect the household electric product to the product service end is shortened in fact.

Further, after the writing control flag in the NFC module of the home appliance is set to the second flag from the first flag, when the change from the low level to the high level is detected, the network allocation information and the IP address in the NFC module of the home appliance may be read.

In some embodiments, the product application may prompt the user that the writing of the distribution network information has been completed after writing the acquired distribution network information and the IP address to the NFC module of the home appliance. For example, the product application may show the prompt text "have successfully written" in the application interface, or may prompt the user by voice "you have successfully written the distribution network information" in order to prompt the user that the distribution network information has been written to the home product, which may start distribution network.

In some embodiments, after writing the obtained distribution network information and the IP address into the NFC module of the home appliance, the product application may prompt the user to take the user mobile device off the sensing area of the NFC module of the home appliance.

It will be appreciated that the user typically needs to bring the sensing area of the NFC module of the user mobile device close to the sensing area of the NFC module of the home appliance, so that an NFC connection is established between the NFC module of the user mobile device and the NFC module of the home appliance. The product application does not need to maintain NFC connection after writing the distribution network information and the IP address into the NFC module of the household appliance by utilizing NFC connection, and in the case, the product application can prompt a user to take the user mobile device away from the sensing area of the NFC module of the household appliance, so that the user knows that the user mobile device is not required to be kept close to the sensing area of the NFC module of the household appliance, and the user experience can be improved.

In addition, in some embodiments, a physical (mac) address of a Wi-Fi module of the home appliance is also stored in an NFC module of the home appliance. The product application can call the NFC module of the user mobile device, read the MAC address of the Wi-Fi module of the household appliance from the NFC module of the household appliance, and request the product server to subscribe for a connection success notification for the household appliance according to the MAC address read from the NFC module of the household appliance. After the Wi-Fi module of the household appliance is connected to the product service end, the product service end can send a product connection success notification message to the product application, wherein the notification message carries the mac address of the Wi-Fi module on the product which is successfully connected. The product application can compare the mac address issued by the product server with the mac address obtained from the product side, and if the mac address is consistent with the mac address, the product application reminds the user that the product is successfully connected to the product server.

The Wi-Fi module of the home appliance is also connected to the control module, which means that the control module can transfer information in the NFC module of the home appliance to the Wi-Fi module.
