The intelligent household appliance is embodied in an internet of things manner under the influence of the internet. The intelligent household appliance connects various devices (such as audio and video devices, lighting systems, curtain control, air conditioner control, security systems, digital cinema systems, audio and video servers, video cabinet systems, network household appliances and the like) in a home together through the Internet of things technology, and provides multiple functions and means such as household appliance control, lighting control, telephone remote control, indoor and outdoor remote control, anti-theft alarm, environment monitoring, heating and ventilation control, infrared forwarding, programmable timing control and the like. Compared with common household appliances, the intelligent household appliance has the traditional living function, integrates the functions of building, network communication, information household appliance and equipment automation, provides an all-around information interaction function, and even saves funds for various energy costs.

Fig. 1 illustrates an application scenario to which an embodiment of the present invention is applicable. As shown in fig. 1, the home device system includes a plurality of home devices (e.g., home device 101, home device 102, and home device 103), a router 200, a cloud server 300, and a mobile terminal 400. The home devices are connected to the network through the router 200, for example, the home device 101 in fig. 1 is connected to the network through the router 200, so that the home devices can communicate with the cloud server 300. The mobile terminal 400 may also communicate with the cloud server 300 after connecting to the network. Therefore, the control and allocation of the mobile terminal to the household appliances and the feedback of the self state information of the household appliances to the mobile terminal can be realized.

The household appliance can be connected with a network through the built-in chip. In the embodiment of the invention, the household appliances can be washing machines, air conditioners, refrigerators, electric cookers and the like, communication interconnection with the mobile terminal is realized through an access network, for example, a user can remotely control the water quantity and the mode of the washing machine to wash clothes, the temperature and the mode of the air conditioner, the cooking mode and time of the electric cooker and the like through the mobile terminal, and the household appliances can also feed back self state information, such as the water quantity, the running time length, the temperature and the like, to the mobile terminal through the cloud server. All transmission regulation and control are simple and easy to implement due to the fact that the household appliances are connected to the network.

Routers, which are hardware devices that connect two or more networks, act as gateways between the networks, and are specialized intelligent network devices that read the address in each packet and then decide how to transmit. It is capable of understanding different protocols, such as the ethernet protocol used by a certain local area network, the TCP/IP protocol used by the internet. Thus, the router can analyze the destination addresses of data packets transmitted by various different types of networks and convert the addresses of non-TCP/IP networks into TCP/IP addresses or vice versa; and then transmitting each data packet to the designated position according to the selected routing algorithm according to the optimal route. The router may connect a non-TCP/IP network to the internet.

The cloud server, which is a cloud server often called a cloud host by a service provider, is a part which is similar to a plurality of independent hosts and is fictionally represented on a group of cluster hosts, and each host in the cluster is provided with a mirror image of the cloud host. The cloud server is more flexible than the traditional server, and the cloud server can freely select the type of the operating system. The flexible capacity expansion can be realized, the problem of insufficient resources caused by sudden service increase of the low-configuration server is not needed to be worried, and the bandwidth is upgraded without halt. Compared with a traditional server, the cloud server is easier to use and more convenient to manage. The cloud server is lower in cost than a traditional server, and capital and operating expenses of software and hardware, technical maintenance and personnel support, facilities and the like of the cloud server are greatly reduced compared with the traditional server.

The mobile terminal refers to a computer device that can be used in mobile, and broadly includes a mobile phone, a notebook, a tablet computer, a POS machine, and even a vehicle-mounted computer. The mobile terminal can realize the remote control of the household appliance after accessing the network without being limited by regions.

Specifically, the

home appliances

101, 102, and 103 are all connected to the network through the router 200, so as to connect the cloud server 300 and the mobile terminal 400, whereby the mobile terminal 400 sends the instruction signal to the cloud server 300, the cloud server 300 sends the instruction signal to the router 200, and the router 200 detects and identifies the destination address of the instruction signal and then sends the destination address to the

corresponding home appliance

101, 102, or 103; the

home devices

101, 102, and 103 may also feed back their own status information to the mobile terminal 400 through the router 200 and the cloud server 300.

However, generally, only one router is equipped for one household, the wall-through performance of the router is poor, some household appliances such as washing machines, water heaters, bedroom air conditioners and the like are located at the corners of the household, so that the WIFI signals are poor, the household appliance devices cannot be well connected to the network, the household appliance devices are disconnected from the router frequently, or disconnected from the server, so that the devices are offline, and the user experience is poor.

Based on the above problems, embodiments of the present invention provide a home appliance and a network access method for the home appliance on the premise of not adding new hardware resources, so as to solve the technical problem that the home appliance has poor networking capability due to weak signal coverage of the home appliance.

Fig. 2 is a block diagram illustrating a hardware configuration of a possible home device according to an embodiment of the present invention.

In some embodiments, the home appliance may be a home appliance to be networked, including a WIFI module and an MCU;

in some embodiments, the WIFI module, also known as a serial port WIFI module, belongs to an internet of things transport layer, and functions to convert a serial port or TTL level into an embedded module that conforms to a WIFI wireless network communication standard, and embeds a wireless network protocol ieee802.11b.g.n protocol stack and a TCP/IP protocol stack. Traditional hardware equipment embedding WIFI module can directly utilize WIFI to join in the internet, is the important component that realizes internet of things applications such as wireless intelligent house, M2M. The WIFI module includes two types of topological forms: infrastructure networks (Infra) and ad hoc networks (Adhoc). The WIFI module can include following several modes of operation: 1. an AP, i.e., a wireless access point, is a creator of a wireless network and is a central node of the network. A wireless router used in a typical home or office is an AP. 2. STA stations, each terminal connected to a wireless network (e.g., laptop, PDA, and other user equipment that may be networked) may be referred to as a station. In the embodiment of the invention, the WIFI module is built in the household appliance equipment, other networks can be accessed through the STA site function of the WIFI module, and the WIFI module can be configured as an expanded access point through the AP function of the WIFI module so as to be used for connecting other equipment with the network.

The MCU, also called a Single Chip Microcomputer (MCU) or a Single Chip Microcomputer (MCU), properly reduces the frequency and specification of a Central Processing Unit (CPU), and integrates peripheral interfaces such as a memory (memory), a counter (Timer), a USB, an a/D converter, a UART, a PLC, a DMA, and even an LCD driving circuit on a Single Chip to form a Chip-level computer, which performs different combination control for different applications. In the embodiment of the invention, the MCU is a control core for enabling the household appliance to access the network, and is used for judging the signal intensity, determining the access point of the household appliance, configuring the WIFI module and the like.

Based on the hardware configuration block diagram of the home appliance shown in fig. 2, some embodiments of the present invention further provide a network access method for the home appliance, as shown in fig. 3.

301, the household electrical appliance to be networked scans the access signal intensity of each access point;

each access point comprises a router and at least one home appliance which is accessed to the network; the home appliances which are already networked configure themselves as extended access points after the home appliances which are already networked access the network through the router;

step 302, the household appliance to be networked determines an access point of the household appliance to be networked according to the access signal strength of the router and the comprehensive signal strength of at least one household appliance already networked;

the integrated signal intensity of the networked household appliances is the signal intensity of the networked household appliances for providing access service for the household appliances to be networked through the router; the comprehensive signal intensity of the networked household appliances is determined according to the access signal intensity of the networked household appliances and the switching signal intensity of the networked household appliances.

Specifically, the networked home appliance refers to a home appliance that has been networked by a router and configures itself as an extended access point, and in the embodiment of the present invention, the home appliance may be a plurality of networked home appliances, and the extended access point and the access point of the router together form a scanning object of the home appliance to be networked. The networked home appliances may be networked directly through a router or indirectly through a router, and the indirect networking through a router means networking through other networked home appliances, and these networked home appliances are also directly or indirectly connected to a router. After the home appliances to be networked scan, according to the access signal strength of the router and the comprehensive signal strength of at least one home appliance already networked, a final access point is determined in the router and the plurality of home appliances already networked according to a preset rule, where the preset rule may be to select an access point with the highest signal strength or select any one of the access points with a strength greater than a certain strength. The integrated signal strength of the networked home appliance may be processed and calculated in various manners, for example, by adding the access signal strength of the networked home appliance to the transfer signal strength of the networked home appliance, and the like, which is not limited in this embodiment of the present invention.

For example, the home appliances to be networked are washing machines, and the home appliances already networked are rice cookers and air conditioners. The electric cooker and the air conditioner are both connected to the network through the router and are configured as extended access points. As shown in table 1, the washing machine scans the access signal strengths of the router and the electric cooker, the air conditioner, and obtains the signal strengths of the electric cooker, the air conditioner access router. The washing machine adds the access signal intensity of the electric cooker and the signal intensity of the access router of the electric cooker to obtain the comprehensive signal intensity of the electric cooker, and adds the access signal intensity of the air conditioner and the signal intensity of the access router of the air conditioner to obtain the comprehensive signal intensity of the air conditioner. The access signal intensity of the router is judged and compared with the comprehensive signal intensity of the electric cooker and the air conditioner, the access signal intensity of the router is judged to be strongest, namely-60 dB, which is more than-70 dB of the comprehensive signal intensity of the electric cooker and-80 dB of the comprehensive signal intensity of the air conditioner, and therefore the access point of the washing machine is determined to be the router. The above are merely examples, and embodiments of the present invention are not limited thereto.

TABLE 1

in some embodiments, the MCU is specifically configured to determine an access point of the home device according to a combined signal strength of at least one networked home device;

in some embodiments, the WIFI module is further configured to access an access point of the home appliance.

Based on the hardware configuration block diagram of the home device shown in fig. 2, another possible network access method for the home device is further provided in the embodiment of the present invention, as shown in fig. 4.

The home appliance to be networked determines an access point of the home appliance to be networked according to the access signal strength of the router and the comprehensive signal strength of at least one home appliance already networked, and the method comprises the following steps:

step 401, when the home appliance to be networked determines that the access signal strength of the router is smaller than a first threshold value, acquiring the switching signal strength of the home appliance to be networked for the at least one networked home appliance;

step 402, determining the comprehensive signal intensity of the networked household appliances according to the switching signal intensity of the networked household appliances and the access signal intensity of the networked household appliances;

step 403, the household electrical appliance to be networked determines an access point of the household electrical appliance to be networked according to the comprehensive signal strength of at least one household electrical appliance already networked;

and step 404, accessing the household appliance to be networked into an access point of the household appliance to be networked.

Specifically, a user first allocates a network to the home appliance device to be networked, so that the home appliance device to be networked is connected to the router, and then determines whether the access signal strength of the router is smaller than a first threshold, where the first threshold is a minimum signal strength or a range within which the home appliance device can access the router to keep a network signal stable, and is related to brands, performances and the like of the home appliance device and the router, and can be determined according to actual experience, such as-80 dB, -90dB, or-90 dB-80 dB, and the embodiment of the present invention is not limited thereto. And under the condition that the access signal strength of the router is judged to be smaller than the first threshold value, determining a final access point according to a preset rule through the comprehensive signal strength of the household appliances which are accessed to the network. The specific steps for determining the access point have been described previously and will not be described again.

For example, the home appliances to be networked are washing machines, and the home appliances already networked are rice cookers and air conditioners. The electric cooker and the air conditioner are connected to the network through the router and are configured as extended access points. As shown in table 2, if the washing machine determines that-100 dB of the access signal intensity of the router is smaller than-80 dB of the first threshold, the signal intensity of the router accessed by the electric cooker and the air conditioner is obtained; and adding the access signal intensity of the electric cooker and the signal intensity of the access router of the electric cooker to obtain the comprehensive signal intensity of the electric cooker, and adding the access signal intensity of the air conditioner and the signal intensity of the access router of the air conditioner to obtain the comprehensive signal intensity of the air conditioner. And judging and comparing the comprehensive signal intensity of the electric cooker and the air conditioner, wherein the comprehensive signal intensity of the electric cooker is judged to be the strongest, namely-70 dB which is more than-80 dB of the comprehensive signal intensity of the air conditioner, so that the access point of the washing machine is determined to be the electric cooker. The above are merely examples, and embodiments of the present invention are not limited thereto.

TABLE 2

the WIFI module is also used for accessing the router.

Correspondingly, when the household appliance to be networked determines that the access signal strength of the router is not less than the first threshold value, the household appliance to be networked accesses the router.

For example, the home appliances to be networked are washing machines, and the home appliances already networked are rice cookers and air conditioners. The electric cooker and the air conditioner are both connected to the network through the router and are configured as extended access points. As shown in Table 3, if the washing machine determines that-70 dB of the access signal intensity of the router is greater than-80 dB of the first threshold value, the washing machine accesses the router and does not judge the comprehensive signal intensity of the electric cooker and the air conditioner. The above are merely examples, and embodiments of the present invention are not limited thereto.

TABLE 3

The embodiment of the invention provides another possible hardware configuration diagram based on the hardware configuration of fig. 2. As shown in fig. 5, the method further includes:

the instruction transceiver is used for receiving and transmitting instructions according to the configuration of the MCU; specifically, if the household appliance to be networked accesses the router, the instruction transceiver can receive instruction information sent by the cloud server through the router and send state information of the household appliance to the cloud server through the router; if the household appliances to be networked access any one networked household appliance, the command transceiver can receive command information sent by the cloud server through the networked household appliance and send self state information to the cloud server through the networked household appliance, and the command transceiver of the networked household appliance can judge a source address and a destination address of a command according to the identification of the command, so that the command is transmitted to the household appliance or the router connected with the household appliance or the router, and then the command is sent to the cloud server by the router. The cloud server and the mobile terminal send and receive instructions and state information, and therefore remote control of the mobile terminal on the networked household appliances is achieved.

In some embodiments, after the home device to be networked accesses the access point of the home device to be networked, the method further includes the following steps, as shown in fig. 6:

601, the access point of the household electrical appliance to be accessed to the network judges whether the household electrical appliance to be accessed to the network is legal or not, if so, the access is allowed, and if not, the access is added to a blacklist and the access is forbidden;

in some embodiments, after the home appliance to be networked accesses the network through the router, the home appliance becomes a networked home appliance, and the MCU built in the networked home appliance is configured to configure itself as an extended access point through the WIFI module; or, configuring the Bluetooth module as an extended access point.

In some embodiments, the WIFI module or the bluetooth module expands the access signal strength of the networked home appliance device according to the configuration of the MCU, so that other home appliance devices to be networked can be connected; the WIFI module or the Bluetooth module of the networked household appliance can send broadcast messages, and the broadcast messages comprise the identification of the networked household appliance, the physical address of the networked household appliance and the switching signal strength of the networked household appliance.

In some embodiments, the WIFI module of the home appliance to be networked scans the WIFI module of the home appliance to be networked or an access point extended by the bluetooth module, and if the home appliance to be networked extends the access signal strength through the WIFI module, the WIFI module of the home appliance to be networked is connected to the WIFI module of the home appliance to be networked; if the household electrical appliance which is connected to the network is to expand the access signal intensity through the Bluetooth module, the WIFI module of the household electrical appliance which is to be connected to the network is connected with the Bluetooth module of the household electrical appliance which is connected to the network.

In order to more clearly describe the method for accessing the network by the home appliance, the network accessing process involved in the embodiment of the present invention is generally described below with reference to fig. 8. As shown in fig. 8, when the first home device and the second home device are not connected to the network in the initial state, a specific network access process may include the following steps:

step 801, a user carries out network distribution on second household electrical appliance equipment;

specifically, when the second household electrical appliance is first networked, the mobile terminal of the user is connected through the WIFI module or the Bluetooth module, and the user configures the connected router for the second household electrical appliance through the mobile terminal. After the first configuration, the second household appliance can directly scan the access signal intensity of the router without a subsequent network distribution.

Step 802, connecting the second household appliance with a router;

step 803, when the second household appliance determines that the access signal strength of the router is greater than a second threshold value, configuring the second household appliance itself as an extended access point through a WIFI module or a bluetooth module;

step 804, the user performs network distribution on the first household appliance;

specifically, when the first household electrical appliance is firstly connected to the network, the mobile terminal of the user is connected through the WIFI module or the Bluetooth module, and the user configures the connected router for the first household electrical appliance through the mobile terminal. After the first configuration, the first household appliance can directly scan the access signal intensity of the router without a subsequent network distribution.

Step 805, connecting the first household electrical appliance to a router;

step 806, when the first household appliance determines that the access signal strength of the router is smaller than a first threshold value, determining the comprehensive signal strength of each second household appliance, and determining the second household appliance as an access point from each second household appliance;

step 807, the first household appliance sends an access request to the second household appliance;

step 808, the second household appliance judges whether the first household appliance is legal or not, and if the first household appliance is legal, the request is passed; adding the illegal information into a blacklist and forbidding access;

step 809, the first household appliance accesses to the network through the second household appliance, so that the first household appliance accesses to the cloud server through the second household appliance to report the state and control the first household appliance by the mobile terminal;
