Problems solved by technology

[0003] At present, the most common way is to use wireless methods, such as ZIGBEE, or the more popular WLAN method, but the control method is relatively simple, and in general technology, it is necessary to use a controller to control each controlled electrical appliance. The networking method is relatively single, and it cannot be adjusted adaptively according to changes in the home environment
For example, home temperature controllers or home light sources, due to the single control method, even if wireless sensor technology is used, it is still impossible to achieve effective control of multiple nodes, so it is necessary to remodel the network used by home smart electrical equipment

example 1

[0022] Example 1: Power Line Carrier Control (PLC) bus mode

[0023] The embodiment of the present invention abandons the use of RS485 bus or general R-type bus, that is, master-slave equipment must be used for communication, and a protocol mechanism is specified on the conventional PLC bus: indoor household electrical equipment, such as portable PCs, televisions or Electrical equipment such as smart refrigerators and air conditioners are used as free nodes AN. Users can start one of the electrical equipment, such as a TV, and send a "registration" request through the interactive interface of the TV itself to establish a local area data network. If there is a device responding to the request REG_REQ in an indoor space, such as a portable PC, then the PC will serve as the basic node BN at this time.

[0024] For example, in order to realize an effective connection between a smart TV and a PC, a handshake circuit or a computer program can be set respectively, so that the communi...

[0039] Example 2: Digital wired dimming (DLT) bus method

[0040] DLT is also a bus protocol based on power lines, that is, it is also applicable to the adjustment communication of lighting equipment carried by power lines. Generally speaking, a control device CD (controldevice), bus (interface) and controller CG (controlgear) are designed in a DLT system, and the control device controls the controller through the bus to perform dimming operations. The coupled lighting device can obtain power through the bus, that is, this method is equivalent to the conventional master / slave device (MASTER-SLAVE) logic. Generally, multiple controllers and their lighting devices are connected in series.

[0041] According to the embodiment of the present invention, the aforementioned automatic "registration" request method can also be used between the control device CD and the controller CG, the difference is that the control conditions for the lamp are limited, such as brightness, color or c...

Abstract

The invention aims to solve the existing problems, and designs a method and system for controlling a network of household user equipment through a power line. Household user electrical equipment can realize automatic networking in a case that it is unnecessary to identify a network structure. The method comprises the following steps that: a plurality of free nodes are set on an indoor network bus; the free nodes are indoor user electrical equipment having a data transceiving function; the free node sends a registration request to other free nodes; if one free node receives the registration request, the free node receiving the registration request is set to a basic node; the free node sending the registration request is set to a service node; and the basic node returns a request response to the service node and distributes one unique code address to the service node. The method and the system disclosed by the invention have the beneficial technical effects that: automatic networking can be realized in the case that it is unnecessary to identify the network structure; the free node can communicate with the basic node through the service node; and thus, the signal connection requirements are reduced.

Description

technical field [0001] The invention belongs to the field of smart home, and in particular relates to a method and system for controlling a home user equipment network through a power line. Background technique [0002] In commercial users, especially in residential buildings, intelligent control methods have been more and more extensively studied. Especially with the continuous intelligence of the electrical equipment used by users in daily life, technologies in corresponding fields have involved the overall control of these user smart electrical appliances or the use of one of them (such as user computers, mobile phones, etc.) to control other electrical appliances. The status of use, such as switch action, temperature, lighting brightness and other factors, belong to the category of smart home technology that is widely mentioned at present. [0003] At present, the most common way is to use wireless methods, such as ZIGBEE, or the more popular WLAN method, but the contro...
