Compare with traditional the Internet, Internet of Things has its distinct feature.Such as, Internet of Things is the extensive use of various cognition technologies.Internet of Things deploy the polytype transducer of magnanimity, each transducer is an information source, the information content that different classes of transducer is caught is different with information format.The data that transducer obtains have real-time, by the collection environmental information of certain frequency period, constantly update data.In addition, Internet of Things is a kind of foundation Ubiquitous Network on the internet.The important foundation of technology of Internet of things and core are still the Internets, by various wired and wireless network and the Internet converged, the information of object are passed real-time and accurately.The informational needs of the transducer timing acquiring on Internet of Things, by Internet Transmission, because its quantity is extremely huge, has formed magnanimity information, in transmitting procedure, in order to ensure correctness and the promptness of data, must adapt to various heterogeneous networks and agreement.
Summary of the invention
The present invention proposes a kind of Internet of Things access method, comprising:
In a webserver, set up comparison list, in the described table of comparisons, at least record a plurality of addresss of node, node name and contrast information thereof in described Internet of Things;
When the described webserver receives the request of one of described a plurality of nodes of hope access from user, from described request, obtain the node name of the node of wishing access;
According to obtained node name, from the described table of comparisons, find out the address of node of this hope access;
Address of node based on described hope access, forms a response message; And
Described response message is sent to described user.
Preferably, in above-mentioned Internet of Things access method, after the step of described formation one response message, described Internet of Things access method further comprises: the node that described response message is sent to described hope access; The described webserver receives the response message from the node of described hope access.
Preferably, in above-mentioned Internet of Things access method, describedly send to described user's step to comprise described response message: when indication allows access in the response message that the described webserver receives, described response message to be sent to described user.
Preferably, in above-mentioned Internet of Things access method, a plurality of addresss of node in described Internet of Things are IPv4 or IPv6 address.
Preferably, in above-mentioned Internet of Things access method, the described step that described response message is sent to the node of described hope access further comprises: by a socket, described response message is sent to the node of described hope access through things-internet gateway; One scheduled wait time was set in the described webserver, and waits for the response message receiving from the node of described hope access.
Preferably, in above-mentioned Internet of Things access method, when failing in the time at described scheduled wait to receive the response message of the node of accessing from described hope, the described webserver sends a refuse information to user.
Internet of Things access method of the present invention has taken into full account the safety requirements in node visit process.By verify to improve the fail safe of node visit operation to the node of hope access.In addition, the present invention also provides the mechanism that effectively reports an error, to improve operability and the operational efficiency of this Internet of Things access method.
Should be appreciated that more than the present invention generality is described and the following detailed description is all exemplary and explanat, and be intended to the further explanation that the invention provides for as claimed in claim.
Accompanying drawing explanation
Accompanying drawing is mainly used for providing further to be understood the present invention.Accompanying drawing shows embodiments of the invention, and with together with this specification, play the effect of explaining the principle of the invention.In accompanying drawing:
Fig. 1 schematically shows the hardware foundation of Internet of Things access method of the present invention.
Fig. 2 schematically shows an embodiment of Internet of Things access method of the present invention.
Embodiment
Below in conjunction with accompanying drawing, describe technical scheme of the present invention in detail.
In the Internet of Things research field that interconnects, the service that how to make Internet user use the existing network equipment and corresponding software accessing internet of things wireless sensor node to provide, is to have very much researching value and Practical significance.It is http hypertext transfer protocol that current Internet of Things application layer protocol mainly adopts most popular application protocol on the CoAP agreement ，Er the Internet that under Internet Engineering task groups one grouping proposes.
For the service that Internet user can accessing internet of things node be provided, need between http protocol and CoAP agreement, translate.The common operational capability of Internet of things node is limited, and memory span is little, so protocol translation can not be realized on Internet of things node.For guaranteeing the convenient enable seamless access Internet of Things of user.Should reduce as far as possible or avoid to add new protocol stack or particular clients software is installed at user terminal.In addition, fail safe is also the technical problem that must deeply consider in prior art.
Fig. 1 schematically shows the hardware foundation of Internet of Things access method of the present invention.Fig. 2 schematically shows an embodiment of Internet of Things access method of the present invention.As shown in the figure, the hardware foundation 100 of Internet of Things access method of the present invention mainly comprises: node 1101, node 2102, node N 103, the webserver 104 and user 105.
In the example depicted in fig. 1, user can conduct interviews to any one or more nodes 101～103 via the webserver 104.
Now, in conjunction with Fig. 2, discuss the operating mechanism of above-mentioned hardware foundation 100 in detail.Fig. 2 schematically shows an embodiment of Internet of Things access method of the present invention.As shown in the figure, Internet of Things access method 200 of the present invention comprises:
