With the rapid development of the Internet of Things today, the smart home industry is also in full swing, and the smart gateway is the most important link in the entire smart home architecture. The smart gateway connects the home intranet and the home extranet to ensure communication between the inner and outer networks. The home intranet is the networking of all electrical equipment in the home. Each smart appliance is regarded as a terminal node, and all terminal nodes are centrally managed and managed by the home smart gateway. Decentralized control; the home extranet refers to the external Ethernet, GPRS, and 4G network, which is used to connect the intelligent management terminals of the home intelligent gateway, such as smartphones, tablet computers, etc., so as to realize remote control and view home information.
Features of Smart Gateway
1. Intelligent access, safe and reliable
2. Healthy network, the safe application
3. Mobile office, fast and secure
The role of smart gateways
The smart gateway is an indispensable part of the smart home. It is the access controller that realizes the operation of the entire smart home system. Its functions include not only the collection, input, and output of information, but also remote and linkage control. Therefore, for smart home manufacturers, producing and developing a good smart gateway is the key to winning users in the market; for consumers, the quality of the smart gateway also determines the quality of the smart home products they buy. overall experience.
Functions realized by the intelligent gateway
1) Ability to perceive network access. First of all, the intelligent gateway has the function of obtaining information such as the attributes and status of each node, that is, it can perceive the real-time status of each node. Secondly, it has functions such as remote control, wake-up, and diagnosis of nodes.
2) Intercommunication capability of heterogeneous networks. The access of intelligent gateways inevitably requires cross-domain communication, so perfect addressing technology is required to ensure that the information of all nodes can be accurately located and queried.
3) Communication and data format standardization. The intelligent gateway must realize the protocol conversion from the sensor network to the traditional communication network, uniformly encapsulate the standard format data transmitted on the protocol adaptation layer, unpack the data sent by the wide-area access layer into standard format data, and realize the command Parse, and then convert into signals and control instructions that can be recognized by the perception layer protocol.
To put it simply, the intelligent gateway mainly completes three tasks, the first is to collect the data of sensor nodes; the second is to perform data protocol conversion; the last is to quickly send the data after protocol conversion to the public network. In addition, it should also have corresponding management and control capabilities.
The huge development potential and broad development prospects of smart homes have caused many businesses to get involved in them. However, to obtain the smart home market, one not only must master smart home products, but the key is to master smart home systems.
