Description

A kind of things-internet gateway system

Technical field

The present invention relates to a kind of gateway system, relate in particular to a kind of things-internet gateway system.

Background technology

Internet of Things is based on that internet development gets up, and is the extension and the expansion of the Internet.Specifically, Internet of Things is exactly " network that the thing thing links to each other ".It is formed framework and mainly is divided into three layers:

Sensing layer is also referred to as sensing layer.Belong to the bottom in the whole architectural framework.Be used to gather all kinds physical quantity data, for example: RFID, data such as infrared induction.The upper strata is passed in these data process simple transformation processing then handles.Through this Internet of Things in several years development.The bottom not merely has been that sensing data reports at present, also has many Control Network to be used to respond the upper strata and beams back next data.

Network layer, this one deck mainly are that the data of sensing layer are handled through corresponding, then according to certain network communication protocol, through the corresponding communication interface, handle above data being sent to the terminal of appointment like: modes such as Ethernet, GPRS, WiFi.

Application layer belongs to the superiors in the whole architectural framework, and this one deck mainly is a corresponding application software, is used to carry out data analysis, functions such as operation and storage.

In the whole architectural framework of Internet of Things, no matter be sensing layer, network layer or application layer have all developed for many years, and technology is comparative maturity all.But want to run through network of formation with these three layers.Must between sensing layer and network layer, exist one " Internet of Things close ", carry out the transmission of data.This Internet of Things closes and connects complicated sensing network or Control Network downwards.The communication network of interconnection technique comparative maturity upwards.So just, can set up perfect Internet of Things one.

Because Internet of Things development at home is at the early-stage, add that the transducer of forming sensing layer is intricate, there are not uniform communication interface and communication protocol, be difficult to search out an independent product on the market and satisfy various demands of applications.At present, the method for head it off roughly is divided into following two kinds on the market:

Adopt special-purpose internet-of-things terminal equipment, reach application demand through the transmission means that changes transducer.Such as: a terminal that possesses zigbee or Bluetooth wireless communication, want to make sensing layer access network layer, must transducer be changed system into the transmission means that possesses zigbee or bluetooth.

Adopt integrated mode to satisfy application demand.This mode is used the widest in the market.Just use various types of collections or control terminal, connect corresponding sensing equipment or control appliance, through a center processing unit these image data and control data are connected to network layer at last.Such as: carry out video data acquiring with a DVR; Carry out the data acquisition of analog sensor with a collection of simulant signal terminal; Add a digital signal acquiring terminal and carry out collection of digital signal data etc.; The data of coming are gathered at these terminals the most at last, are transmitted to center processing unit, carry out data processing by it and pass to network layer then.

Yet there is following shortcoming in the solution that is adopted in the market:

Very flexible shows that mainly corresponding solution specificity is too strong, has so just limited later upgrading and transformation;

Autgmentability is poor, because the sensing layer of the Internet of Things bottom is of a great variety, does not also have unified interface and agreement, and this just requires collecting unit and the control unit on upper strata can flexible expansion, can adapt to various types of underlying device;

Networking capability is poor; Most of in the market solution networking mode all belongs to simply replys the formula networking; What have does not even possess networking capability, just can cause the system failure if this has just caused a unit to go wrong, and brings many inconvenience for later network operation;

Poor stability, poor stability are mainly reflected in the integrated form scheme, because the probability that breaks down of each unit all is equal relatively in the integrated form scheme, this just causes the total failure rate of whole system to increase; In addition, in the special equipment that has, all be that a processor carries out the operation of total system, system's situation out of service when this has also caused processor to break down.

Poor stability because the network layer of Internet of Things belongs to outer net, if communication link does not carry out encryption, will cause data to leak outside and illegal invasion, has reduced the degree of safety of whole system, and upgrading and poor from the ability of maintenance certainly.

In sum, prior art can not satisfy people's demand.
