4G Industrial Smart Gateway

　　4G Industrial Smart Gateway

　　The industrial-grade IoT gateway is a data transmission device that fully supports the 4G/3G/2G communication networks of China Mobile, China Unicom and China Telecom. The 4G smart gateway realizes two-way and transparent communication between serial devices and servers, and between serial devices and serial devices. , Wireless transmission, the Internet of Things gateway has the characteristics of simple use, USB/Bluetooth configuration, remote maintenance, etc. It can easily develop user monitoring software or dock third-party application platforms through cloud platform forwarding, protocol development kits, network-to-serial tools, etc.

　　The role of 4G industrial smart gateway:

　　 Smart gateway is an indispensable part of smart home. It is the 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 for them to win users in the market; for consumers, the quality of the smart gateway also determines the quality of the smart home products they buy. The overall experience.

　　 4G industrial intelligent gateway realizes the function:

　　1) Ability to perceive network access. The smart gateway first has the function of acquiring 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) Interoperability of heterogeneous networks. Smart gateway access must have requirements for cross-domain communication, so a complete addressing technology is needed to ensure that the information of all nodes can be accurately located and inquired.

　　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 Analysis, and then converted into signals and control instructions that can be recognized by the perception layer protocol.

　　 To put it simply, the smart gateway mainly completes three tasks. The first is to collect data from sensor nodes; the second is to perform data protocol conversion; and the last is to quickly send the data after the protocol conversion to the public network. In addition, it should also have corresponding management and control capabilities.
