Referring to fig. 1, the multicast distribution network method includes the following steps, and it should be noted that the step combination order defined in this embodiment is only used to illustrate this embodiment, and is not used to define other combination orders of the steps in this application:
s1: the mobile device obtains a WiFi name of a current WiFi.
Specifically, the mobile device may be an intelligent device such as a mobile phone and a notebook, which is capable of networking and has a function of scanning surrounding WIFI signals; in the application, taking a mobile phone as an example, a program is preset in a memory of the mobile phone, and when the setting of scanning WiFi around the mobile phone is turned on, the preset program obtains a WiFi name scanned by the mobile phone.
S2: and acquiring the distribution network information of the current WiFi name.
Specifically, in this embodiment, the distribution network information is SSIDS and a key of WiFi.
Taking the operation of the mobile phone as an example, a preset program in the mobile phone is opened, a WiFi name acquired by the preset program of the mobile phone is displayed on a screen of the mobile phone, and an operator can input the distribution network information by clicking the WiFi name; optionally, the WiFi connection setting of the mobile phone may also be opened for an operator, one of the surrounding WiFi signals is connected, then a preset program in the mobile phone is started, and the preset program directly acquires the WiFi name and the distribution network information of the current connection of the mobile phone.
S3: and encrypting the distribution network information.
The encryption mode is an encryption mode agreed with a product end in advance, the product end refers to a product needing a distribution network, in the embodiment, the distribution network information is encrypted by adopting an AES encryption algorithm, and encrypted transmission is carried out by adopting BASE 64. But other encryption algorithms can be adopted, so that when the distribution network information is sent, other people are prevented from easily acquiring the distribution network information in a mode of grabbing empty packets, and the password leakage is prevented.
S4: a communication channel is established with the product side.
In this embodiment, the product end can be intelligent refrigerator, intelligent oven, intelligent robot of sweeping the floor etc. in intelligent house.

S6: and searching unicast information from the product end for confirming the success of the distribution network.
After receiving the distribution network information, the product end analyzes the SSID and the secret key according to a preset encryption mode, and when the distribution network is successfully distributed, the product end sends unicast information to the mobile equipment for operators to confirm, and optionally stops sending the distribution network package after receiving the unicast information.

s7: and if the unicast information is searched, deleting the IP information corresponding to the unicast information from the current IP group.
When a network is distributed, a plurality of distribution network products may need to be distributed, and in an intelligent home, the distribution network products are different in placement position due to different functions, for example, an intelligent refrigerator is generally placed in a kitchen, and an intelligent sound box is generally placed in a living room; because the positions of the distribution network products are different, the strength of signals for receiving data of the distribution network products is easily different, and the time for accessing the distribution network is different. After the distribution network of the distribution network product is successful, the mobile device receives the unicast information, analyzes the IP information in the unicast information, and then deletes the IP of the device which has successfully distributed the network from the preset IP group, so that the situation that the distribution network information is repeatedly sent to the distribution network product which has successfully distributed the network is avoided, and the operator can know which distribution network products have not successfully distributed the network, and can timely check the reason why the distribution network has not succeeded.
In this embodiment, a predetermined port may be opened at the mobile device to multicast transmit the distribution network packet and receive unicast information.
S8: and continuously using a multicast mode to send the distribution network packet containing the distribution network information to the product end corresponding to the current IP group.

(2) And continuously and circularly transmitting the network distribution package by multicast until a transmission stopping signal is obtained, and clicking by an operator to stop transmitting the signal to trigger the transmission stopping.
The mobile equipment is preset with a setting capable of selecting a corresponding mode, and the first mode is adopted, so that the condition of accessing a distribution network can be accurately known, and the intelligent control effect is achieved, but a judgment and deletion program needs to be additionally installed on the mobile equipment, and the operation resources of the mobile equipment end are greatly occupied during actual use; if the second case is selected, manual monitoring is required, and if the second case is not closed in time, processing resources of the mobile device are occupied for a long time.
Optionally, after the multicast mode is started to send the distribution network packet, the resource occupation condition of the mobile device is detected in real time, and the multicast sending mode is switched in real time according to the resource occupation condition of the mobile device.
After a multicast mode is started to send a network distribution packet, if the resource occupation of the mobile equipment is detected to be less, starting a first multicast sending mode, and updating a product end IP in an IP group in real time according to the condition of a product end network distribution; when detecting that the mobile equipment resources occupy more resources, switching to a second multicast sending mode, and taking the IP group updated last as the IP group sent by multicast in the mode; in this embodiment, more resource occupation of the mobile device means that the resource occupation is greater than 60%, less resource occupation means that the resource occupation is less than 60%, and the specific proportion can be set according to actual requirements.

and repeatedly sending the protocol header in a multicast mode, so that the product end locks the channel and establishes point-to-point connection with the mobile equipment, and the product end receives the distribution network information.
By multicast sending protocol head, the product end can lock the channel and establish point-to-point connection with the mobile equipment.
Optionally, in another embodiment, a protocol header may be broadcast in a loop, and the number of loops may be set according to actual requirements, for example, 3 times, 4 times, 5 times, and the like are sent in a loop, in this embodiment, 3 times is taken as an example; scanning a protocol head by a product end, locking a channel for the first time, and then scanning the protocol head for two times so as to determine the stability of the channel; if the first sending of the protocol header causes the product end not to receive the protocol header because of network reasons or current channel instability, the product end can establish connection again by sending the protocol header twice subsequently.
Channel stability judging logic can be preset at the product end, namely the number of times of cyclic sending of the protocol head is known in advance, and the product end judges that the protocol head receiving the preset number of times can judge that the channel is stable and lock the channel. For example, taking the protocol header is sent circularly 3 times, in the predetermined time, the channel stability determination logic preset at the product end may determine that the channel is stable and lock the channel to receive the subsequent data if the protocol header is received for more than or equal to 2 times; if the number of times of receiving the protocol heads is less than 2, the channel is judged to be unstable, the protocol heads are continuously scanned until the number of the received protocol heads is more than 2, and the current channel is locked. The predetermined time may be the maximum time required for cyclically transmitting the protocol header, or may be set according to actual conditions.
