User client, household electrical appliance, and control method thereof

Abstract

The invention relates to the household electrical appliance field, and discloses a user client, a household electrical appliance, and a control method thereof. The control method comprises steps that a type of a network used for controlling a device is determined; following items are carried out by aiming at different network types based on corresponding communication protocols: a request of subscribing to the state of the device is transmitted; the state information of the device responding to the subscription request is received; an instruction of controlling the device is transmitted based on the state information. A wide area network or a local area network is used to control the device according to a use condition, and the reliability of the control is guaranteed, and the efficiency of the control is improved.

Description

technical field [0001] The present invention relates to the field of home appliances, in particular to a user client, a home appliance and a control method thereof. Background technique [0002] The Internet of Things is an important part of the new generation of information technology, and it is also an important stage of development in the "informationization" era. The Internet of Things uses communication technology to connect sensors, controllers, machines, people and things together in a new way to form a relationship between people and things, things and things (such as machine-to-machine, Machine-to-Machine (M2M)). Connected to realize informatization, remote management control and intelligent network. [0003] In the prior art, the Internet of Things implements communication between different objects either through a wide area network or through a local area network. For example, the home Internet of Things usually implements M2M communication via a local area netw...

Problems solved by technology

Generally, the routers used in the home use the NAT function. If the private LAN of the 192.168.1.0 network segment is set up in the home, the CoAP multicast query message cannot pass through the home gateway.

If an IoT device is not in the home LAN, it cannot discover the objects that need to be connected. For example, a mobile phone using a 3G or 4G network cannot automatically discover the IoT appliances at home.

[0004] Although there is, for example, an MQTT (Message Queuing Telemetry Transport) server-based push mechanism that can complete the discovery function of IoT device resources, a general home LAN does not deploy an MQTT server, and the broadband wireless router in the home does not Will integrate MQTT server function

Moreover, as an embedded device, ordinary smart home appliances have limited resources, so they cannot integrate MQTT server functions

So if the home broadband gateway fails, devices on the LAN will not be able to discover each other

[0005] Moreover, if the devices in the Internet of Things are only connected through the WAN, when the user monitors the status of the Internet of Things devices at home, the message needs to be forwarded through the remote server, which will have a delay problem and affect the user experience.
