It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The specific embodiment is as follows:
as shown in the figure, the universal internet of things interface management platform comprises a protocol server, a rule engine, a basic module, a logic module, a database and a management module; the protocol server bears the response service request, bears the service and ensures the normal operation of the service of each protocol, and is provided with a plurality of protocol interfaces, such as MQTT Broker, a TCP/IP server, HTTP/RESTful, Websocket, CoAP and other interfaces of various protocols so as to correspond to the services connected under different protocol rules. The rule engine receives the data transmitted by the protocol server, inputs the data, explains the business rules and makes corresponding business decisions according to the business rules. If a service request accesses a record stored in the database and copies the record, the rule engine performs corresponding operation after receiving the record. In the setting, the rule engine comprises a front rule engine and a rear rule engine which are elastically combined, the two rule engines are responsible for different works, and a front rule engine middleware is called before actual business logic processing is carried out and is used for identity verification or a module needing front processing for authority judgment; the post-arranged rule engine middleware is called after the actual business logic is processed, is used for responding certain actions, is mainly used for responding multiple applications of the business, and does not influence the actual business logic under the condition that the processing result of the post-arranged rule engine middleware is unimportant or whether the processing result is required to be successful or not. The basic module comprises an oAuth module, a user module and an equipment module, and is responsible for processing basic services according to specific requirements of the services, such as reading data of a certain sensor. The logic module is responsible for logic operation and setting a logic structure, some requests which need to carry out logic operation enter the logic module to be processed, when the database needs to be accessed, the requests can be accessed through the logic module, and some simple accesses can be carried out from the basic module. The database stores and manages data. And the management module manages specific user requests and presents response results. In the device, a specific data connection structure of the platform is that a protocol server is connected with a client service, a preposed rule engine is arranged at the rear end of the protocol server, a basic module is arranged at the rear end of the preposed rule engine, a logic module and a database are arranged at the rear end of the basic module in parallel, the logic module is connected with the database, a postposition rule engine is arranged behind the logic module and the database, and a management module is arranged at the rear end of the postposition rule engine.
In the device, in order to better perform operation and response on requests of different protocols, a protocol server is provided with a route processing module, the route processing module reads an address in each data packet and then determines how to transmit the data packet, after a platform receives the request from a client/terminal/node, a corresponding protocol server in the platform processes and applies the request to correctly obtain the client request, the client request is collected to a route processing service in a unified mode, and after the route processing service receives different requests, the route is judged and verified, mainly data matching, demand judgment and data distribution are performed.
In the device, the specific flow of data entering the platform is as follows:
s1: a client makes a service request;
s2: the protocol server receives the request, when the platform receives the request from the client/terminal/node, the corresponding protocol server side processing application in the platform correctly obtains the client request, and the client request is uniformly summarized to the routing processing service;
s3: after receiving different requests, the route processing service judges and verifies the route;
s4: a front rule engine: the filtered route enters the middleware of the preposed rule engine for processing;
s5: and (3) service processing: after the rule engine processing is finished, a part of the basic business is processed through the basic module, and has special requirements, if the business processed logically enters the application logic in the actual logic module for processing, according to different businesses, developers need to develop different business logics, set different logics and perform different logic processing;
s6: the post rules engine responds with: after the business logic module finishes processing, the request is correspondingly processed and fed back to the management module for specific management or displaying or publishing corresponding data (in a protocol of a publish/subscribe mode) after the middleware of the rule engine is arranged in the back.
In this process, a relatively optimized response is that when two or more services have the same user data, or similar user processing logic, the services share the user module in the base module.
The scheme provides a scheme capable of flexibly combining multiple Internet of things protocols so as to deal with different application scenes and realize different functions and requirements; and can be used as a container for flexible distributed deployment.
The scheme supports protocols such as Socket access, HTTP/HTTPS, Websocket/Websockets, MQTT/MQTTS, CoAP and the like. Different Internet of things applications can be supported by supporting protocols such as Socket, MQTT and CoAP. Meanwhile, the self-supporting HTTP and Websocket can conveniently support various requirements and functions and can conveniently provide a uniform or self-defined management entrance.
Besides supporting various internet and internet of things protocols, the multi-application unified access is realized, the request of each application is forwarded in parallel, and the scheme can uniformly manage each application and comprises functional modules of application authentication, data management, data visualization and the like.
Because the self-supporting protocol comprises the HTTP protocol, the WebSocket protocol and the like, a user can select to deploy the unified application management module according to actual conditions.
The scheme solves the problems of protocol shortage of EMQX and multi-application management capability, meanwhile, the scheme can also be used for splitting or combining each module according to actual implementation to realize an optimal or minimized solution, each implementation is used as a node to carry out flexible distributed deployment, the implementation of the distributed deployment is adopted, and the scheme also provides an entrance for flexibly managing each node, so that the problems of singleness and inflexibility of China Mobile OneNet and Ariyun Internet of things platforms are solved.
