Description
Technical field
The present invention relates to Internet of Things field of communication technology, in particular at a kind of platform of internet of things Interworking Data transformat
Reason method.
Background technique
In " internet+" and " made in China 2025 " epoch, China's Internet of Things is quickly grown, but in development process, general
Store-through is flat in terminal communication of internet of things platform and internet-of-things terminal hardware compatibility difficulty problem, especially a terminal communication of internet of things
Platform need to dock it is even more extremely difficult when different industries different manufacturers difference internet-of-things terminal device protocol, mainly include it is following several
:
Data point, the required data of different industries different manufacturers monitoring are different with the information to be controlled, therefore, each factory
Family's internet-of-things terminal equipment communication protocol is also different, and the Service control and communication process of terminal communication of internet of things platform are difficult；
Different internet-of-things terminal equipment communication protocols are different, every to increase a kind of new terminal equipment and need to increase a kind of agreement,
It needs to carry out secondary development to terminal communication of internet of things platform, needs to spend a large amount of human and material resources and financial resources；
Different terminal equipment, different communication protocol, different data format, different business logic, different Encryption Algorithm cannot
It is mixed, the transactional and complexity of terminal communication of internet of things platform are increased, system compatibility problem and unstability are easily led to.
Summary of the invention
The present invention is the compatibility and stability in order to solve the problems, such as existing terminal communication of internet of things platform, and improves number
According to transmission security, a kind of versatility that can be realized terminal communication of internet of things platform, different terminal equipment and not jljl are provided
The access of working application control platform is not necessarily to secondary development, the communication process encryption of Internet of Things application control platform and terminal device
Algorithm is flexibly matched with, and terminal communication of internet of things platform does not constrain it, terminal communication of internet of things platform not processing business logic
And business process, the data communication of processing terminal equipment and Internet of Things application control platform, it simplifies process and business is complicated
The platform of internet of things Interworking Data transformat processing method of degree；Distinct device, different command group, the different lives of same order group
It enables and uses different Encryption Algorithm between packet, not only solve the compatibility issue of platform of internet of things and internet-of-things terminal, Er Qieti
High data transmission security, even if a kind of Encryption Algorithm is cracked, other Encryption Algorithm are unaffected, and know the algorithm
Other algorithms not being cracked can be changed to after being cracked at any time.
To achieve the goals above, the present invention uses following technical scheme, a kind of platform of internet of things Interworking Data transmission lattice
Formula processing method is transmitted applied to the data of Internet of Things application control platform and terminal communication of internet of things platform, using request packet
And response bag, the request packet format are made of request packet packet header and request packet backpack body, the request packet packet header defines
The unique identifier of internet-of-things terminal equipment, the request packet backpack body are arranged by multiple groups order group, every group of life
Group is enabled to be made of order packet, mailing address and Rule of judgment, the order packet is by order serial number, command recognition number, order
Message, command checksum mode, Encryption Algorithm and six part of public key composition, the mailing address is by response message mailing address
Beginning position, address size and compare character three parts composition, the Rule of judgment by response message Rule of judgment initial position,
