Plug and play method of family wireless control network

Abstract

The invention relates to a plug-and-play method for household wireless control network, belonging to the field of household wireless control network. It is characterized in that the information for differentiating each household equipment identity is provided by adopting the frequency error of a crystal apparatus of single chip master control circuit in a wireless communication device on each household equipment or simultaneously adopting the timing function of a gateway in the crystal frequency error and household wireless network, instead of setting sole MAC address for each household equipment in the household network previously, thereby forming a household wireless control network taking the household gateway as the server terminal and each household equipment as the customer terminal of network node. Wherein, each network node can generate sole identity identification automatically in the process of distributing address automatically, thereby avoiding the repeated distribution of the gateway to the address in the household wires control network and realizing plug and play. The invention has the advantages of high reliability, wide application, plug and play, needlessness of MAC address and low cost.

Description

technical field [0001] The invention belongs to the technical field of home wireless control network, and relates to the plug and play technology therein. Background technique [0002] Emerging home network technology has gradually changed the status quo of traditional home appliances being used as separate control devices, and the interconnection and information sharing between devices has become a trend. Although the home network technology realizes the interconnection between devices, the early home network needs to be manually configured when it is established and changed. The process is extremely cumbersome and cannot be completed automatically, which brings great inconvenience to users and hinders The promotion of home network technology. In order to solve this problem, the plug-and-play technology applied to the network appears, which is used to realize the automation of network configuration and networking process. However, most of these technologies are based on t...

Problems solved by technology

[0009] 1) MAC addresses need to be managed and allocated by a global organization (such as IEEE), which requires a large management cost

[0010]2) Any manufacturer that needs to produce hardware that can be used as a node device or an interface device in a home network needs to apply for and purchase a MAC address from the global management agency, which increases the Increased production costs and entry barriers for hardware manufacturers, limiting the development of many small and medium-sized enterprises

[0011]3) With the growth of network scale and the development of device network, more and more network nodes (including various embedded devices) need to assign MAC addresses, which Putting the MAC address space in danger of being exhausted

[0012]4) At present, most network devices or interfaces (including home networks), the MAC addresses in their hardware can be rewritten (in fact, many small businesses and R&D institutions do so), which greatly increases the possibility of network address conflicts, so that the MAC address scheme cannot actually guarantee the uniqueness of network node identification

If the manufacturing process and device parameters of two network nodes are exactly the same, the biggest difference between them is the spatial location, but this difference is difficult to use
