Description

Things-internet gateway and communication protocol automatic adaptation method

Technical field

The present invention relates to the Internet of Things application technology, relate in particular to a kind of things-internet gateway and the sensor node that adopts different technologies is communicated agreement adaptive method automatically.

Background technology

The notion of Internet of Things (The Internet of Things) is proposed in 1999 first by Massachusetts Institute Technology (MIT) the earliest, initial notion is meant all article by radio-frequency (RF) identification information sensing equipment and Internet connections such as (RFID), realizes the network of intelligent identification and management.International Telecommunication Union expanded the connotation of Internet of Things notion in 2005, point out in this report, the target of Information ﹠ Communication Technology connects anyone from any time, any place, develop into the stage that connects any article, and the connection of all things on earth has just formed Internet of Things.

In the Internet of Things that this part report is mentioned, except that the RFID technology, more new technology, for example: technology such as transducer, embedded chip, cellular mobile communication are widely used.Comprehensively perception, reliably transmit, Intelligent treatment is the feature of Internet of Things: " perception comprehensively " is meant that perception such as utilizing radio-frequency (RF) identification (RFID), two-dimension code, GPS, camera, transducer, sensor network, the technological means of catching, measuring carry out information gathering to article whenever and wherever possible and obtain; " the reliable transmission " is meant the fusion by various communication networks and the Internet, with article (Things) access information network, carries out reliable information interaction and shared whenever and wherever possible; " Intelligent treatment " is meant various intelligence computation technology such as utilizing cloud computing, fuzzy diagnosis, the cross-region of magnanimity, inter-trade, interdepartmental data and information are carried out analyzing and processing, lifting realizes intelligentized decision-making and control to the insight of physical world, economic society comings and goings and variation.Internet of Things is that variation and the influence that global economic and social development is brought will surmount the Internet far away.

Internet of Things by universally recognized definition is: it is a huge social information system that is made of jointly sensing layer, network layer, application layer.Sensing layer is responsible for the perception acquisition of information, and network layer is responsible for message transmission is arrived application layer, and application layer is analyzed and handled by perception and signal transmitted, realizes the perception between thing and thing, people and the thing.

Internet of Things is with various information sensing equipment, a huge network that combines formation as radio-frequency (RF) identification (RFID) device, infrared inductor, global positioning system, laser scanner, household electrical appliance, security protection equipment etc. and the Internet, allow all article and network link together, convenient identification, management and monitoring, realize the application of fusion on this basis, finally provide immanent all-around service for people.

The radio sensing network that is in sensing layer is made up of a large amount of microsensor nodes usually, adopt the short-distance wireless communication mode to form the wireless network of multi-hop automatically between each node in the local scope, the information of these sensing node collections at first is pooled to Centroid by radio sensing network, by gateway device information is forwarded to the management platform of far-end then.

Radio sensing network gateway device in the market adopts the data transmission equipment of separation or router that the information of radio sensing network is forwarded to the back-stage management platform mostly, wherein connects by serial ports usually between gateway device and the radio sensing network Centroid.But at present there is following shortcoming in things-internet gateway equipment: at first, lacks unified standard because the short range wireless transmission technology is very many, present usefulness RFID, ZigBee, bluetooth, Z-Wave etc. are arranged more widely.Both just for a kind of transmission technology, as ZigBee, the practical application standardization level was not high yet, and a lot of manufacturers are based on proprietary protocol oneself exploitation transport module or transmission chip, so the ZigBee chip chamber of different vendor can't intercommunication.Therefore wireless sense network isomery often; things-internet gateway equipment in the market often only customizes at specific cases; be unfavorable for the development of Internet of Things industrial scale; gateway device is the radio sensing network of adaptive these isomeries how; the otherness of shielding wireless sense network; making between the wireless sense network of isomery, can realize collaborative work between wireless sense network and the communication network, is the problem that presses for solution.

In addition, present gateway device is only done transparent forwarding to sensing network information, make at present a lot of industry Internet of Things application systems be in the state of local, separation, the various information sensing equipment accepted standards of front end are multifarious, much also adopt enterprise's proprietary protocol, the information of gathering also only limits to propagate, analyze and processing in the industry specialized application scene among a small circle in, and do not have really to realize that Internet of Things can be runed, can manage, the construction object of controlled, trusted and information sharing.

Chinese patent CN200810057221.7 proposes the extendible wireless sensor network gateway equipment of a kind of Internetworking Approaches, can carry out exchanges data with each node of radio sensing network and to other forwarded.How but the technical scheme that this patent proposes adapts to different communication networks so that be implemented under the various application scenarioss and can transmit radio sensing network information easily if only being confined to solve gateway device, do not relate to the radio sensing network that how to adapt to front end different technologies specification and then form unified interface standard.

Chinese patent CN200610169744.1 proposes a kind of wireless sensor network gateway equipment, adopt the GPRS radio-cell to realize communicating to connect between remote server and the radio sensing network, how its technical scheme does not relate to adaptive various radio sensing network yet.

In sum, a kind of gateway device that can adapt to the various radio sensing networks of front end, possess standard interface of the development need of Internet of Things, by this gateway device can be really with thousands upon thousands radio sensing networks insert one can run, can manage, the Internet of Things of controlled and information sharing.
