Embodiment Construction
[0027] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0028] figure 1 It shows a schematic structural diagram of a home network system in an embodiment of the present invention. The home network includes a home main gateway and several home control sub-gateways connected to the home main gateway. Each home control sub-gateway is connected to several subnetworks Devices, etc., that is, in this way to achieve interconnection with smart home devices.
[0029] A gateway-centric home network consists of the following parts:
[0030] The specific classification of a1 gateway;
[0031] a2 explains the role of the gateway;
[0032] a3 clarify the core position of the gateway in the home network architecture;
[0033] 2 A gateway-centered device mutual discovery method includes the following steps:
[0034] b1 Establishment and maintenance of home control subnet;
[0035] The b2 device completes registration...

The embodiment of the invention discloses two digital home network inter-equipment mutual discovery methods. One method comprises the following steps that: a first home control sub-gateway sends a search request in a digital home network by using a simple service discovery protocol (SSDP); intelligent home equipment receives the search request, determines whether to match a home control sub-gateway according to a search condition, and transmits a unicast SSDP response to be disseminated in digital home network equipment if the intelligent home equipment is matched successfully; the first homecontrol sub-gateway receives an SSDP response message and acquires a uniform resource locator (URL) list for accessing the intelligent home equipment by analyzing XML (extensible markup language) format information of the URL in the SSDP message; and the first home control sub-gateway transmits the acquired URL list to each home control sub-gateway in the digital home network by adopting a simpleobject access protocol (SOAP). Through the implementation of the method, the intelligent home equipment is convenient to control and maintain by the user.
Description
technical field [0001] The invention belongs to the technical field of digital home networks, and in particular relates to a method for mutual discovery between digital home network devices. Background technique [0002] With the vigorous development of the digital home industry, people's lives are becoming more and more convenient, and various home appliances have more and more functions to facilitate users' use and improve user experience. Good feedback from users on new products has prompted companies to devote themselves to developing smarter home appliances that integrate more functions. With the development and progress of science and technology, more and more smart home appliances have been put into production and use, and human home life has entered the era of digital smart home. [0003] The smart home devices in the existing digital home network are all isolated in the digital home network, which are mainly connected with the corresponding home control sub-gateway...
