Problems solved by technology

[0005] This application proposes a network abnormality processing method, device, and home appliances to realize that after the network connection of the equipment fails and it is determined that there is an abnormality, it can automatically detect that the cause of the abnormality is an IP address conflict, thereby solving the problem of the network connection of the equipment in the prior art. During the process, when the server cannot be connected due to IP address conflicts, it is necessary to manually troubleshoot the abnormal cause and waste a lot of time for technical problems

Embodiment 1

[0032] figure 1 It is a schematic flowchart of a network exception handling method provided in Embodiment 1 of the present application.

[0033] Such as figure 1 As shown, the network exception handling method is executed by the home appliance side, and specifically includes the following steps:

[0034] In step 101, the network connection of the device fails, and it is determined that there is an abnormality.

[0035] In the embodiment of the present application, during the process of connecting to the router, the device requests the router of the local area network to obtain a static IP address through the DHCP protocol, so as to connect to the server according to the obtained static IP address. Determine whether there is any abnormality in the network connection by judging whether the network connection is successful when the device connects to the server according to the static IP address.

[0036] Among them, the static IP address is a fixed IP address assigned to the ...

Embodiment 2

[0057] figure 2 It is a schematic flowchart of a network exception handling method provided in Embodiment 2 of the present application.

[0058] Such as figure 2 As shown, it specifically includes the following steps:

[0059] In step 201, the device sequentially queries the physical address corresponding to each IP address in the network segment of the LAN.

[0060] In the embodiment of the present application, when the device requests the static IP address obtained from the router to connect to the server through the DHCP protocol, after the network connection fails, the physical address corresponding to each IP address can be sequentially queried in the network segment of the LAN.

[0061] Step 202, judging whether each IP address in the network segment has a corresponding physical address.

[0062] After the device successfully connects to the network according to the IP address of the network segment of the LAN, there is a physical address corresponding to the IP add...

Embodiment 3

[0076] image 3 A schematic flowchart of a method for handling network exceptions provided in Embodiment 3 of the present application;

[0077] Such as image 3 As shown, the specific implementation process of the method includes the following steps:

[0078] In step 301, the device requests a router of the local area network to assign a second IP address.

[0079] In the embodiment of the present application, when the device is powered on and connected to the network, it first needs to request the router of the local area network to assign the second IP address through the DHCP protocol.

[0080] Step 302, the device configures the IP address as the second IP address.

[0081] In the embodiment of the present application, after the device obtains the second IP address assigned by the router of the local area network, configure the IP address of the device as the second IP address, so as to use the second IP address to connect to the server.

[0082] It should be noted tha...

Abstract

The present application proposes a network abnormality handling method, device, and home appliance, wherein the method includes: after the device fails to connect to the network, after determining that there is an abnormality, query the first idle IP address in the local area network, and the device transfers the IP address from the pre-configured first IP address to The second IP address is changed to the first IP address, and the device queries the physical address corresponding to the second IP address, and determines that the abnormality is an IP address conflict. As a result, when there is an abnormality in the network connection of the device, the IP address conflict problem can be automatically detected, which solves the problem of requiring the user to manually find out the cause of the network connection failure in the prior art when the device cannot connect to the server during the network connection process. Technical issues that lead to a lot of wasted time.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for handling network abnormalities, as well as home appliances. Background technique [0002] With the rapid development of the Internet of Things and smart home appliance technology, more and more users control the smart home appliances through mobile terminal devices, so the smart home appliances first need to be connected to the network. In the prior art, when a home appliance is connected to a network, most of them request an Internet Protocol Address (Internet Protocol Address, hereinafter referred to as an IP address) from a router through a Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, hereinafter referred to as DHCP). Furthermore, the home appliance uses the acquired IP address to communicate until the lease of the IP address expires, and then re-applies for an IP address. [0003] However, when obtaini...
