Description
Technical field
The present invention relates to Internet of Things field, particularly, relate to a kind of non-real time one-way link communication method for Internet of Things.
Background technology
Internet of Things, by embedding a kind of short-range mobile transceiver in various articles for daily use, by communication dimension new for acquisition one in the Information And Communication world, expand to people from the interpersonal communication connection in any place any time and be connected with thing and the communication between thing with thing.Although domestic at present, the unified standard definition of neither one also to Internet of Things, but from Internet of Things in essence, Internet of Things is a kind of polymerism application and skill upgrading that occur after modern information technologies develop into certain phase, various cognition technology, modern network technology and artificial intelligence are polymerized and Integrated predict model with automatic technology, people and thing wisdom are talked with, creates the world of a wisdom.Because the development of technology of Internet of things has almost related to the every aspect of information technology, be a kind of polymerism, systematic innovation and application and development, the third time revolutionary character innovation of information industry of being also therefore just known as.
Internet of Things is by various sensing technology (RFID, transducer, GPS, video camera, laser scanner etc.), various means of communication (wired, wireless, long distance and short distance etc.), any object is connected with the Internet, to realize telemonitoring, automatic alarm, control, diagnosis and maintenance, and then realize a kind of network of " management, control, operation " integration.
In existing Internet of Things framework:
Allly the transducer of resolution digital agreement or controller all can be called intelligent node, and the node not possessing this function often carry on one " proxy gateway ", thus become a large wisdom node.Can communicate with one another between wisdom node, and most data more can by the server of internet transmission to far-end, as shown in Figure 1.And Internet of Things is laid equal stress on often for the requirement of " perception " and " control ", therefore must carry out both-way communication between server and wisdom node, this is for the network environment of complexity, is the thing that a difficulty is larger.This patent achieves a kind of intelligent node and server when requirement of real-time is not high, and low cost, has the communication scheme of highly compatible and robustness.As shown in Figure 2, the communication scheme of existing Internet of Things must set up the link of a both-way communication, and link is upwards used for sending the data collected to server, equipment state etc., downward link is then that server assigns action command to intelligent node, amendment parameters etc.
But for various communication connected modes, above-mentioned requirement is not can be gently readily accessible.Intelligent node is often due to distributed more widely, the method that frequent employing accesses nearby, this considerably reduce the cost laying basic network, improve the feasibility of Internet of Things project, but access way method is more nearby, such as PPPOE Dial-up Network, local area network (LAN) adds proxy server access, when there is no good cut-in method, also GPRS can be adopted, the access waies such as 3G.Therefore time most of, node can have access to server, can carry out the process of data upload and download at any time, but server cannot have access to node, can not send data at any time to node.
For ensureing both-way communication, existing Internet of Things will use the technology such as VPN, and this will introduce more complicated hardware, or has higher requirement for the software development of intelligent power saving.Meanwhile, under different method for network access, the technology adopted for realizing both-way communication has certain difference, and this result also in intelligent node cannot be general, simply can not change access way.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of non-real time one-way link communication method for Internet of Things, to realize low cost, the advantage of compatibility and high robust.
For achieving the above object, the technical solution used in the present invention is:
For a non-real time one-way link communication method for Internet of Things, comprise the following steps:
Server adds node ID the order will issuing certain node, and is the unique ID of each peer distribution, and by the demanded storage of additional node ID in the order data storehouse of server;
When above-mentioned node is by one way link access services device, from mentioned order database, inquires the order that node ID is corresponding with this node ID, and perform this order;
Execute above-mentioned be attached with the order of node ID after, above-mentioned node is access services device again;
If this order had received, then need not perform this order, directly delete;
When above-mentioned node continues access services device, querying command database, until all orders in order data storehouse all perform.
Technical scheme of the present invention carries out unidirectional access by intelligent node to server, sets up one way link, and server cannot send the information such as order directly to intelligent node, needs intelligent node initiatively to obtain the order of issuing it.Thus reach low cost, the object of compatibility and high robust.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is existing the Internet architecture schematic diagram;
Fig. 2 is the structural representation that existing the Internet connects;
Fig. 3 is the link structure schematic diagram of the non-real time one-way link communication method for Internet of Things of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
As shown in Figure 3, a kind of non-real time one-way link communication method for Internet of Things, comprises the following steps:
Server adds node ID the order will issuing certain node, and is the unique ID of each peer distribution, and by the demanded storage of additional node ID in the order data storehouse of server;
When node is by one way link access services device, from order database, inquires the order that node ID is corresponding with this node ID, and perform this order;
After executing the order being attached with node ID, node is access services device again;
If this order had received, then need not perform this order, directly delete;
When above-mentioned node continues access services device, querying command database, until all orders in order data storehouse all perform.
The means of communication disclosed in technical solution of the present invention, improve the real-time that order is assigned, as long as improve the frequency of node visit server, access in as every in an intelligent power saving 10 seconds server, the order of then issuing this node will be obtained by node and be responded for 10 seconds at the latest, for the Internet of Things application that requirement of real-time is low, this time can also lengthen, 1 hour or 1 day.
In sum, the present invention also has the following advantages:
1. low production cost, without the need to installing extra protocol conversion device.
2. low development cost, software and hardware realizes simple.
3. compatible strong, network environment complicated in any case, can normal communication.
4. good stability, realize simple, the link that can go wrong is few.
5. save server resource, a large amount of intelligent node accesses can be supported.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
