Description
Technical Field
The invention relates to a network distribution system and a network distribution method, in particular to a system and a method for quickly realizing network distribution of a plurality of WiFi devices, and belongs to the technical field of WiFi connection of smart homes.
Background
WiFi connection is the short-distance wireless local area network communication technology which is used most at present, and has the advantages of high speed, networking, simplicity and convenience in use, data safety and the like. The mobile communication network is widely used in home, office and partial industrial fields, is complementary with a mobile communication network, and has important technical position and application market.
Before WiFi connection, a newly-accessed device needs to complete authentication, and the most important step is to input an SSID (the name of a WiFi hotspot, which is generally a character string) and a corresponding password of a target AP, and then to perform connection. Since the mobile phone and the computer (hereinafter, collectively referred to as a terminal) have rich computing and interactive resources, the SSID can be obtained through WiFi hardware scanning, and the password is input by using a keyboard, so that connection is completed. However, for embedded hardware devices applied in the fields of smart home and internet of things, the SSID cannot be directly screened by a user and complicated passwords cannot be input because of being limited by interactive resources.
Therefore, the distribution network of the WiFi device is a key and important process for the embedded device with simple structure and limited resources. If the special design is not adopted, the use experience of a user is greatly influenced, and even the solution can be solved by paying the cost of structure, cost and the like.
As shown in fig. 1, the network is a conventional one-key distribution network, and specifically, the network is a WiFi module in an embedded device, and operates in a packet capture mode, and then monitors WiFi messages in an environment. And the message embeds the coded SSID and password in the specific field. The terminal places information such as SSID (service set identifier) and password of the target AP at a specific position in the message according to the requirement of the WiFi module, broadcasts the information in a circulating way, unpacks the information after the WiFi module captures the message and obtains the SSID and the password; and then initiates the final connection.
The method for distributing the network is simple for users. However, there are several problems, and very prominent, mainly: 1) And safety problems: the password is broadcast in the environment and can be intercepted by anyone. 2) Poor compatibility: because the WiFi module is in a random packet capturing state and is influenced by factors such as environmental channel fluctuation, other AP (WiFi access point: an opposite end to which WiFi equipment is connected, which can be a common access point or a router), interference, a network mode of a terminal and the like, the failure rate can be randomly increased; if the frequencies of the terminal connections do not match, it may even fail 100%. 3) And the terminal cannot acquire the information of the peripheral equipment because of one-way communication.
Security issues are fatal to sensitive users. Compatibility problems can affect almost all users, and users are usually very confused due to the randomness of the environment, and user satisfaction is greatly reduced. Furthermore, the process of the terminal discovering the device in the local area network requires that the terminal must establish a connection with the target AP, and usually introduces significant delay, which also degrades the user experience.
As shown in fig. 2, the existing commonly used AP distribution network form is provided, specifically, the existing commonly used AP distribution network form is a WiFi module in an embedded device essentially, and works in a single AP mode, and then the terminal establishes a connection with the AP to exchange information required by both sides, including information such as a target SSID, a password, and a device serial number. And after the WiFi module acquires the information, switching the mode, actively connecting the target AP, and if the information is effective, finishing the connection.
The success rate of the pure AP distribution network is good. However, the disadvantages of this approach are evident: 1) Only WiFi networking information is transmitted, and no user information exists; 2) And whether the transmitted information is valid or not cannot be known. 3) Only one device can be distributed at a time, and the efficiency is low.

Specifically, the distribution network terminal 0 is a source of information distribution, and terminal distribution network information can be sent through the distribution network terminal 0, where the terminal distribution network information includes and is not limited to target AP information, and in addition, the terminal distribution network information may further include user information, terminal information, task information, and the like, generally, the user information includes status information such as an identity of a user, the terminal information includes related information such as a terminal identity, and the task information may be a related status of the user information, the terminal information, and the like, and specific contents may be selected as needed, and are not described herein again.

The distribution network terminal 0 mainly has a distribution mode. Specifically, the distribution network terminal 0 may provide an AP hotspot function by corresponding WiFi function hardware, and perform external services with an agreed SSID and a password known to the network device 1 to be distributed. When the network distribution equipment 1 is connected to the AP hotspot of the network distribution terminal 1, handshaking is performed to determine mutual information after the connection is successful, and the process and manner of specifically determining the information may be in a conventional form, and the specific process is well known to those skilled in the art and is not described herein again.

As can be seen from the above description, the distribution network terminal 0 operates in the AP mode, the to-be-distributed network device 1 can be connected to the distribution network terminal 0 according to the agreed SSID and the password corresponding to the agreed SSID, and the connection process between the to-be-distributed network device 1 and the distribution network terminal 0 is consistent with the existing WiFi connection form, and the agreed SSID and the password corresponding to the agreed SSID are stored in advance in each to-be-distributed network device 1, so that the to-be-distributed network device 1 can send a connection request to the distribution network terminal 0 or the distribution network device through the agreed SSID and the password corresponding to the agreed SSID only after scanning the agreed SSID, and after confirmation by the distribution network terminal 0 or the distribution network device, the to-be-distributed network device 1 can be connected to the corresponding distribution network terminal 0 or the distribution network device.
In the embodiment of the present invention, the device 1 to be configured is a device to be networked, and after the device 1 to be configured is connected to the target AP, the device 1 to be configured automatically becomes a network distribution device, that is, the device 1 to be configured connected to the target AP realizes a network distribution, and at this time, the device 1 to be configured becomes a network distribution device. The distribution network device needs to be disconnected from the distribution network terminal 0 or other distribution network devices. In order to quickly realize the distribution network of a plurality of devices 1 to be distributed, the distribution network device successfully connected with the target AP can also send device distribution network information, the devices 1 to be distributed can be connected with the adjacent distribution network devices by using the appointed SSID and the passwords corresponding to the appointed SSID, after connection, the distribution network devices can send device distribution network information to the successfully connected devices 1 to be distributed, according to the target AP information in the device distribution network information, the devices 1 to be distributed can send connection requests to the target AP, and after the devices 1 to be distributed are successfully connected with the target AP, the distribution network is successful, so that the distribution network devices are changed into the distribution network devices. When the distribution network equipment 1 becomes the distribution network equipment and can send the distribution network information of the equipment, the connection state between the distribution network equipment and the target AP can be kept, the connection state between the distribution network equipment and the target AP can also be disconnected, the connection state between the distribution network equipment and the target AP can be specifically selected as required, and the detailed description is omitted here.
When all the devices 1 to be distributed are connected with the target AP and become distribution network devices, the distribution network operation among the devices 1 to be distributed can be realized. In the whole process, the distribution network terminal 0 is only required to send terminal distribution network information to the adjacent to-be-distributed network equipment 1, and the to-be-distributed network equipment 1 is connected with the distribution network terminal 0 and can be connected with the target AP according to the terminal distribution network information. After the device to be configured with the network is connected with the target AP, the device distribution network information can be sent to the adjacent device 1 to be configured with the network, so that the connection between the rest devices 1 to be configured with the network distribution device and the connection with the target AP can be realized, and the purpose of rapidly realizing the distribution of the plurality of devices 1 to be configured with the network can be achieved. In specific implementation, when a plurality of distribution network devices and/or distribution network terminals 0 exist near the to-be-distributed network device 1, the to-be-distributed network device 1 may select a mode with a closest distance or a strongest signal to realize connection with the corresponding distribution network device or distribution network terminal 0.
As shown in fig. 4, the device to be configured 1 includes an information exchange control module 12, and a WiFi STA module 11 and a WiFi AP module 13 connected to the information exchange control module 12;
the information exchange control module 12 can be connected with the distribution network terminal 0, the target AP or the distribution network equipment through the WiFi STA module 11; the information exchange control module 12 can send the device distribution network information through the WiFi AP module 13, so as to implement connection with the device 1 to be distributed.
In the embodiment of the present invention, the WiFi STA module 11 and the WiFi AP module 13 may adopt the existing common form, that is, the WiFi STA module 11 needs to be connected to the WiFi AP to realize network communication. The WiFi AP module 13 is a WiFi access point, that is, an opposite end to which the WiFi device is to be connected, and may be a common access point or a router. The information exchange control module 12 may adopt the existing commonly used implementation form, such as a circuit, a chip, or a microprocessor chip with a control function, which may be specifically selected according to the needs and will not be described herein again.
Further, the device to be networked 1 can operate in a receiving mode or a distribution mode; when the network is distributed, the equipment 1 to be distributed enters a receiving mode;
when the wireless network distribution device works in a receiving mode, the information exchange control module 12 scans nearby appointed APs through the WiFi STA module 11, sends connection requests to the appointed APs by the appointed SSID and the passwords corresponding to the appointed SSID, sends the requests to the target APs according to the obtained target AP information after the connection with the appointed APs is successful, and starts the WiFi AP module 13 by the information exchange control module 12 after the connection with the target APs is successful so that the device 1 to be distributed enters a distribution mode;
when the distribution network equipment works in the distribution mode, the information exchange control module 12 controls the WiFi AP module 13 to be in the working state of the appointed AP, so as to allow the connection between the nearby network equipment 1 to be distributed and the WiFi AP module 13, and the information exchange control module 12 can send the equipment distribution network information to the network equipment 1 to be distributed, which is connected to the WiFi AP module 13, through the WiFi AP module 13.
In the embodiment of the invention, the equipment 1 to be configured works in the receiving mode before the terminal distribution network information or the equipment distribution network information is obtained. In the receiving mode, the information exchange control module 12 controls the WiFi STA module 11 to scan the default AP of the nearby default SSID (the device 1 to be networked can connect with the default AP by using the default SSID and the password corresponding to the default SSID). After the scanning, the WiFi STA module 11 actively connects to the agreed AP, sends a request for reading the distribution network information (terminal distribution network information or device distribution network information), and tries to connect to the target AP after returning the information. If the connection is successful, the working mode is switched, the information exchange control module 12 starts the WiFi AP module 13, establishes an AP point with the agreed SSID as the name, enters the distribution mode, and can send the device distribution network information to the outside.
Specifically, the WiFi STA module 11 is used to implement connection with other AP hotspots, and the opposite end may be a distribution network information distribution hotspot or a target WiFi hotspot. The WiFi AP module 13 is used to start an AP hotspot, and can distribute the device distribution network information to other devices 1 to be distributed. The information exchange control module 12 is configured to control start and stop of the WiFi STA module 11 and the WiFi AP module 13 and read or send data, so as to manage acquisition, maintenance, and sending of distribution network information in the entire system.
Once the device 1 to be distributed enters the network-to-be-distributed mode, the device will first enter the receiving mode. In a receive mode: the information exchange control module 12 starts the WiFi STA module 11 and turns off the WiFi AP module 13. And then controls the WiFi STA module 11 to scan for the agreed SSID. If the scanning is finished, the connection is immediately established, and the distribution process is started. The distribution process includes several steps of mutual authentication confirmation, request sending, request responding, connection confirmation, etc., and the specific process and step implementation of the specific distribution process may adopt the existing common technical means, and the specific implementation process is well known to those skilled in the art and will not be described herein again.
After the receiving mode is completed, it indicates that the correct and effective distribution network information (equipment distribution network information or terminal distribution network information) is received. The received information may then be used to distribute to other devices 1 to be networked for distribution, and the devices may go into distribution mode.
In the distribution mode: the information exchange control module 12 activates the WiFi AP module 13. And waiting for the WiFi STA module 11 of other equipment 1 to be networked to access. When other devices 1 to be distributed access to the network in a receiving mode, a distribution process is started, which comprises several steps of mutual authentication confirmation, request acceptance, request response and the like. In the distribution mode, the information exchange control module 12 may close the WiFi STA module 11, and certainly, may also keep the working state of the WiFi STA module 11, and may specifically select according to actual needs, which is not described herein again.
As shown in fig. 5, in the state transition of the device 1 to be networked, there are two main states: a reception mode and a distribution mode. Specifically, the user operates to enter the distribution network mode, and first enters the receiving mode, that is, prepares to receive the distribution network information. In the receiving mode, a receiving work flow is executed, which includes processes of scanning for an SSID of a default AP, connecting, identifying, sending a request, receiving distribution network information, and the like, and a specific receiving work flow can be realized by a conventional and commonly-used technical means, and a specific realizing process is well known by those skilled in the art and is not described herein again.
And after the receiving process is finished, the information is transferred to an information confirmation state. And confirming the information, namely confirming the received distribution network information. Including attempting to establish a WiFi connection with the target AP in order to confirm the networking information; other ancillary information is confirmed including, but not limited to, user information, task information, and the like.
And if the information is confirmed to be completed successfully, switching to a distribution mode to work. The distribution mode is a passive service mode, i.e. listening for requests and then servicing the requests. The distribution mode starts to work according to a distribution flow, and comprises the steps of waiting for connection, identifying a terminal, receiving a request and sending distribution network information confirmed to be effective before. The distribution mode is repeated monitoring, when no new access equipment exists, the distribution mode is quitted overtime, and the whole process is ended.
As shown in fig. 6, it is a flow chart of a receiving mode of the device 1 to be configured, specifically, the device 1 to be configured is triggered by a user first, and enters a network distribution state. At this time, the device 1 to be networked is in a receiving mode. The information exchange control module 12 controls the WiFi STA module 11 to start working, scans nearby WiFi APs, and checks whether there is an agreed AP (i.e., SSID, such as AP _ CFG, which is described later). If the appointed AP is not scanned, the retry is delayed, and if the retry is overtime, the distribution network state is directly exited.
If the agreed AP is found in the list of WiFi AP names nearby, the information exchange control module 12 controls the WiFi STA module 11 to initiate connection to the agreed AP with the agreed password so as to receive the distribution network information of the distributed target AP.
After establishing connection with the agreed AP, the information exchange control module 12 is responsible for establishing connection of network layer, and then exchanging information (including but not limited to device information of both parties, name and password of target AP). The device information of the two parties can be used for mutual validity verification to prevent misconnection of non-cooperative endpoints. The name and password of the target AP are necessary information of the distribution network.
After the name and password of the target AP are obtained, the information exchange module 12 controls the STA module 11 to initiate connection to the target AP. If the connection is successful, it indicates that the networking information of the target AP is valid, and the network distribution process of the device to be distributed 1 is completed, and becomes a network distribution device, and can be used as an information distribution source of other devices, and can also directly exit.

The distribution mode is favorable for rapidly completing the distribution of a plurality of devices 1 to be distributed, and the distribution mode has exponential improvement compared with the mode of connecting one device each time.
After entering the distribution mode, the information exchange control module 12 controls the WiFi AP module 13 to start up, and establishes a distribution AP hotspot according to an agreed name and password. And waiting for the access of other devices 1 to be distributed.
If the network-to-be-distributed device 1 is to be accessed, the information exchange control module 12 establishes a network service, monitors the appointed port, and waits for the device to initiate a request. When the request packet is received, the information exchange control module 12 decodes the request data, and confirms the validity thereof. After the validity is confirmed, the information control module 12 controls the WiFi AP module 13 to distribute the networking information of the target AP to the accessed device. The device 1 to be networked, which fails to confirm validity, cannot receive a response of the device itself, and the design can protect the password from being revealed.
After receiving the networking information, the accessed device 1 to be connected to the network operates according to its own "receiving mode", and at this time, the device 1 to be connected to the WiFi AP module 13 of the current network distribution device is disconnected.
After the distribution work is completed or the idle time is out, the information exchange control module 12 may turn off the WiFi AP module 13, and exit the distribution mode. And ending the whole distribution network process.
