Gateway system of Internet of things

Abstract

The invention discloses a gateway system of Internet of things, which comprises a main control module, a data protection module, a power management module, an audio and video acquisition module, a man-machine operation interface module, a communication interface module and a storage interface module; all the modules are connected through a system bus; and the system bus is used for sensing a data signal which is sent by a sensing level to the main control module, and sends out an instruction signal which is processed by the main control module. The gateway system of Internet of things has low power consumption and a small size, can adapt to various application occasions, has high stability and very flexible expansion, can adapt to various sensing networks and communication networks on a bottom level, and solves the problems of audio and video acquisition, compression and transmission with the lowest cost.

Description

technical field [0001] The present invention relates to a gateway system, in particular to an Internet of Things gateway system. Background technique [0002] The Internet of Things is developed based on the Internet and is the extension and expansion of the Internet. Specifically, the Internet of Things is the "network of connected things". Its composition structure is mainly divided into three layers: [0003] Sensing layer, also known as perception layer. It belongs to the bottom layer of the whole system architecture. Used to collect various types of physical quantity data, such as: RFID, infrared sensing and other data. These data are processed through simple transformation and then passed to the upper layer for processing. After several years of Internet of Things development. At present, the bottom layer is not only for sensor data reporting, but also for many control networks to respond to the data sent back by the upper layer. [0004] Network layer, this lay...

AI Technical Summary

Problems solved by technology

[0011] Poor flexibility, mainly manifested in the fact that the corresponding solutions are too specific, which limits future upgrades and transformations;

[0012] Poor scalability, because there are many types of perception layers at the bottom of the Internet of Things, and there is no unified interface and protocol, which requires the upper-layer acquisition unit and control unit to be able to flexibly expand and adapt to various types of bottom-level equipment;

[0013] Poor networking capability. Most of the networking solutions on the market today are simple responsive networking, and some do not even have networking capabilities. This causes system failure if a unit fails. Network maintenance brings a lot of inconvenience;

[0014] Poor stability, poor stability is mainly reflected in the integrated scheme, because the failure probability of each unit in the integrated scheme is relatively equal, which causes the overall failure rate of the entire system to increase; in addition, in some special equipment In the system, one processor runs the whole system, which also causes the system to stop running when the processor fails.

[0015] Poor security, because the network layer of the Internet of Things belongs to the external network, if the communication link is not encrypted, it will cause data leakage and illegal intrusion, reducing the security of the entire system, and poor self-upgrade and self-maintenance capabilities

[0016] In summary, existing technologies can no longer meet people's needs
