Protocol self-adaptive internet-of-things gateway system

Abstract

The invention discloses a protocol self-adaptive internet-of-things gateway system. The protocol self-adaptive internet-of-things gateway system comprises a communication interface module, a central processing unit and a data storage module. The central processing unit comprises a self-adaptive protocol module, a data analysis module, a data encryption module, a data transmission module and a WEB service module. Internet-of-things devices and access interfaces of a third-party system are offered externally by the communication interface module. Self-adaptive processing is conducted on a communication protocol of each connected internet-of-things device by the self-adaptive protocol module through configuration data, so that an interaction order which can be identified by each internet-of-things device and a data analysis method are generated. The data transmission module supplies a data obtaining interface externally. Through a communication order, an external system or an upper gateway node obtains data in a gateway or operates the internet-of-things devices used for managing the gateway. According to the WEB service module, a user name and a code are input by a user according to the HTTP, so that the user has direct access to limited WEB pages inside the gateway. The protocol self-adaptive internet-of-things gateway system has the advantages of being good in expansibility and strong in cascading capacity.

Description

technical field [0001] The invention belongs to the technical field of gateway systems, in particular to a protocol adaptive Internet of Things gateway system. Background technique [0002] The Internet of Things refers to information sensing devices such as RFID, infrared sensors, GPS, and laser scanners. According to the agreed agreement, information exchange and communication can be realized at any time, any place, and any object, so as to realize intelligent identification, positioning, and tracking. , monitoring and management of a network. There are various access methods to the Internet of Things. The Internet of Things gateway device is the most suitable key device for integrating multiple access methods and interconnecting to the access network. The gateway can meet the access requirements of short-distance communication in local areas. , realize the connection with the public network, and complete functions such as forwarding, control, signaling exchange, codec, e...

Problems solved by technology

[0003] Because there are many types of IoT devices and there is no unified data communication protocol interface, the IoT gateway devices currently on the market have the following disadvantages: (1) Poor scalability: mainly manifested in the fact that the device is too specific and restricts the types of access devices (2) Poor cascading capability: Poor connection and communication capabilities between gateway devices in the same network; (3) Poor security: If the data communication on the insecure communication link is not encrypted, it will be It will cause data leakage and illegal intrusion, reducing the security of the entire system

[0004] To solve the above problems, it is necessary to develop a set of general gateway protocols. Chinese patent (object model for general gateway design, application number 200810029513.X, application date 2008-07-16) discloses an object model for general gateway design, Using the protocol management class, a set of protocols is developed for each type of equipment, and the extension of the gateway equipment protocol is realized. The equipment developed by this method has a large amount of secondary development and the choice of IoT equipment for end users. Disadvantages of small room
