Description
Technical Field
The invention belongs to the technical field of new-generation information, and particularly relates to an improved communication method, equipment and system of an M2M Internet of things applied to a new-generation information technology.
Background
The original concept of the internet of things was proposed by the united states of america, and all articles were connected through the domain name of the internet of things for information exchange and communication, so as to realize a network concept of intelligent identification, location, tracking, and the like. Of course, the official definition of the internet of things is: the process of making communication between objects which are not communicable is called Internet of Things (Internet of Things) based on the Internet.
Compared with a sensor network, the Internet of things has inheritance and breakthrough for the sensor network.
Three elements of the sensor network: research and development of sensors, perception objects and observer sensor networks: the sensor network research began at the end of the 20 actual 90 s. Since the beginning of the 21 st century, sensor networks have attracted considerable attention from academia, military and industrial sectors, and the united states and europe have successively initiated many research programs on wireless sensor networks.
The thermal, infrared, sonar, radar and seismic signals in the surrounding environment are measured by means of sensors built into the nodes, thereby detecting material phenomena including temperature, humidity, noise, light intensity, pressure, soil composition, size, speed and direction of moving objects.
Computer network technology represented by the internet is a great result of computer science in the twentieth century, brings profound changes to our lives, however, the network functions are more powerful, the network world is more abundant, the network world is finally virtual, the network world is still separated from the real world where we live, in the network world, the real world is difficult to perceive, many things are impossible, and the times call for new network technology. The sensor network is a brand new network technology which is brought forward in such a background, integrates the technologies of sensors, low power consumption, communication, micro-electro-mechanical systems and the like, and is expected to bring revolutionary changes to the life style of people in the near future.
The key technologies of the sensor network comprise network topology control, network protocols, network security, time synchronization, positioning technology, data fusion, data management, wireless communication technology, embedded operating systems and application layer technology. They can also be classified as large-scale networks, ad hoc networks, dynamic networks, reliable networks, application-related networks, data-centric networks.
The Internet of Things is an Internet of Things covering everything in the world by utilizing technologies such as RFID (radio frequency identification devices) and wireless data communication on the basis of the computer Internet. In this network, items (goods) can "communicate" with each other without human intervention. The essence of the method is that the radio frequency automatic identification (RFID) technology is utilized, and the automatic identification of articles (commodities) and the interconnection and sharing of information are realized through the computer internet.
RFID, however, is just one technology that enables an item to speak "openly". In the concept of the internet of things, the RFID tags store standard and interoperable information, the information is automatically collected to a central information system through a wireless data communication network to realize the identification of articles (commodities), and further, the information exchange and sharing are realized through an open computer network to realize the transparent management of the articles.
The concept of the Internet of things breaks through the traditional thinking. The past thought has been to separate the physical infrastructure from the IT infrastructure: airports, roads, buildings on the one hand, and data centers, personal computers, broadband, etc. on the other hand. In the era of the internet of things, reinforced concrete and cables are integrated with chips and broadband into a unified infrastructure, so that the infrastructure is more like a new earth construction site, and the world runs on the infrastructure, wherein the infrastructure comprises economic management, production operation, social management and even personal life.
As the number of internet of things devices continues to increase, communication or connectivity between these devices has become an important consideration. According to Gartner's research, the number of internet of things devices will reach 204 hundred million by 2020. There are several internet of things communication protocols available that have different capabilities, data rates, coverage, power and memory, and each protocol has its own advantages and more or less disadvantages. Some of these communication protocols are only suitable for small household appliances, while others can be used for large smart city projects.
M2M (multimedia machine) controls the equipment effectively through mobile communication, so as to expand the business boundary greatly, create a more efficient operation mode than the traditional mode, or create a completely new service completely different from the traditional mode. M2M centers on device communication control and applies information transmission that was originally inefficient or even impossible to achieve in commerce to gain greater competitiveness. The business model of M2M is currently applied in vain, and mainly includes mobile logistics management (M-registration), mobile payment (M-POS), mobile monitoring (M-monitoring), and the like.
M2M is a machine-to-machine conversation that transfers data from one terminal to another. M2M is not a new concept, but is also a phenomenon common to people, such as an entrance card for work, barcode scanning in supermarkets, and NFC mobile phone payment which is popular in the future. Many years ago, NEC corporation of japan has made much publicity and work on M2M and has launched a number of leading M2M products worldwide, successfully in many areas.
The invention provides an M2M Internet of things improved communication method, equipment and a system applied to a new generation information technology, wherein a unique first compiler, a first M2M receiving relay and a second M2M receiving relay are introduced, a plurality of transmission range field middleware are used for managing Internet of things nodes and transmission range field middleware related information of the nodes of the Internet of things under the jurisdiction while M2M Internet of things load data is received, an improved message wrapper is introduced for carrying out classification statistics on the transmission range field middleware received by the first compiler and the distribution information of the nodes of the Internet of things under the jurisdiction, different coding indexes are adopted for coding according to different Internet of things node membership types and are combined with load data, and finally, message wrapping is carried out according to the transmission range middleware information which is reported by the second M2M receiving relay and is received and related to the nodes of the Internet of things as check information, the method realizes higher security guarantee for data transmission of the new generation of information technology M2M Internet of things.

As a stackable preferred embodiment, for the first M2M receiving relay, it receives the internet of things load data sent by the M2M internet of things node to the first M2M receiving relay, where at least the identification information of the M2M internet of things node is carried, for example, the above-mentioned internet of things node identifications 1-6 are 00000001 and 00000110,
as a preferred embodiment that can be superimposed, for the second M2M receiving relay, it receives a relay forwarding feedback signal from the M2M internet of things node to the second M2M and carries its own identifier, where the feedback signal at least includes an identifier of the transmission range field middleware, such as the transmission range field middleware identifier 1 (which is assumed to be 00000001) described above.
Referring to fig. 4 again, it can be seen that the improved packet encapsulator identifies and records the transmission range field middleware to which the internet of things node belongs based on the information received by the first compiler, for example, the internet of things node identifiers 1-6 belong to the first transmission range field middleware, the internet of things node identifiers 7-12 belong to the second transmission range field middleware, and so on, referring to fig. 1 again, in a special case, for example, the internet of things node 1 may belong to both the first transmission range field middleware and the second transmission range field middleware management, and in this case, the improved packet encapsulator records that the internet of things node 1 belongs to both the first transmission range field middleware and the second transmission range field middleware management.
The improved message wrapper classifies the nodes of the Internet of things according to the recorded attribution conditions of the nodes of the Internet of things, and wraps the messages of the Internet of things needing to be sent to the access nodes by adopting different coding indexes according to the classification to obtain combined coding messages; and sending the joint coding message to an access node.
As a preferred embodiment that can be superimposed, the improved encapsulator can include a table of home and code index correspondences. The attribution condition and coding index corresponding table at least comprises an attribution condition column and a coding index column, wherein the attribution condition column comprises all possible attribution conditions of the internet of things nodes, and the attribution condition column is marked by using the transmission range field middleware identification in a descending order, for example, the transmission range field middleware and the second transmission range field middleware belong to the first transmission range field middleware and the second transmission range field middleware simultaneously, and the transmission range field middleware is marked as 0000000100000010; for example, only the first transmission range field intermediate is designated 00000001, for example, both the first and the second and the third transmission range field intermediate are designated 000000010000001000000011. The code index column contains code indexes corresponding to all possible attribution conditions of the internet of things nodes, and the load data and the codes of the feedback signals forwarded by the M2M internet of things nodes to the second M2M are coded by using the coding modes corresponding to the indexes.
As a preferred embodiment that can be superimposed, the improved packet encapsulator receives that the M2M internet of things node receives the relay forwarding feedback signal to the second M2M and carries its own identifier, and finds a corresponding code index from the attribution condition and code index correspondence table through the identifier of the M2M internet of things node, and finds a corresponding coding mode according to the code index, so as to perform coding of the corresponding coding mode on the transmission range field middleware identifier in the feedback signal, which is connected to the load data as an independent field, i.e., as described above, the coding mode corresponding to the index is used for performing coding of the load data and the M2M internet of things node receives the relay forwarding feedback signal to the second M2M.
As a preferred embodiment that can be superimposed, the improved message wrapper encrypts the encoding mode and sends it to the access node.
As a preferred embodiment that can be superimposed, the corresponding relationship between the coding index and the coding mode can be specified by using an index table in the improved packet encapsulator.
For example, a typical correspondence relationship between the coding index and the coding method is shown below.
As described above, as can be seen from the association table of the attribution status and the coding index, for example, the load data of the internet of things node and the feedback data thereof only attributed to the 00000001 identification transmission range farm middleware are coded with the coding index of 1, so the corresponding coding method is UTF-8, and the UTF-8 coding method is used to jointly code the load data and the feedback data thereof.
As a preferred embodiment that can be superimposed, the access node stores an attribution condition, a coding index correspondence table and an index table that are consistent with an improved message wrapper, decrypts the coding mode after receiving the message, analyzes the message, obtains a transmission range field middleware identifier in a feedback signal transmitted by the internet of things node information, verifies the attribution condition corresponding to the coding mode, and if the attribution condition is consistent with the attribution condition, proves that the data source is reliable and is not tampered, improves the data transmission security of the internet of things system, and can reflect the actual attribution position of the internet of things node in the area governed by the access node, thereby providing position guidance and convenience for positioning and system operation.
