Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the detailed description is presented by way of example only and is not intended to limit the invention.
Example 1
In this embodiment, a method for guaranteeing normal operation of an internet of things gateway based on data link switching is provided, and the method is applied in an internet of things scene, where the internet of things scene includes a central server (including access service, data pipeline, processing service, and storage service), a plurality of gateways (deployed on a project site, gateway A, B, c.) and a plurality of internet of things devices (devices 1,2,3, and..n.).
The gateway is responsible for receiving the data of the terminal device and forwarding the data to the access service of the central server. The same type of device data is completed by the same parsing program (different types of device load data formats need to be processed separately). The gateway manages how many kinds of terminal devices and how many kinds of parsing programs exist.
The central server is primarily responsible for processing and storing data and providing it for use by other applications. The access service manages multiple gateways and transmits their forwarded data to the upstream data pipe. And the processing and storage service in the central server consumes the data in the pipeline to complete the service function.
Temporary gateway services are deployed in the central server, and the gateway services mainly analyze and clean the data of the terminal equipment, and then combine the data into a data pipeline for other services.
As shown in fig. 1, in this embodiment, the method of the present invention includes the steps of,
S1, starting a central server, and deploying relevant programs of the Internet of things; including access services, data pipes, processing services, storage services, temporary gateway services, etc.;
S2, the construction and operation staff go to each construction site to deploy a plurality of gateways and terminal equipment; the constructor can deploy the physical fixed gateway and the terminal equipment, and the operation and maintenance personnel are responsible for testing whether the network and the data are normal or not, and the deployment of the scene of the Internet of things is completed at the moment;
S3, when the Internet of things system normally operates, the data reported by the terminal equipment reaches a central server through a normal data link, and is stored or provided for other applications;
S4, the gateway monitors whether the data of each terminal device are normal in real time, and if no abnormality is found, the S3 is returned; if the data of a certain terminal device is found to be abnormal, entering S5;
s5, the gateway marks (does not analyze) the abnormal data of the terminal equipment, and directly transmits the abnormal data to the central server, and after the central server accesses the service identification tag, the abnormal data are transferred to the temporary gateway, and the abnormal data are analyzed in the temporary gateway; if the abnormal data of a certain terminal device causes abnormal temporary gateway service of the center server, the data of other terminal devices cannot be influenced, and the temporary gateway service of the center server is restarted.
The gateway can label the abnormal data in various modes and in various languages. The labeling of the abnormal data is generally to label the abnormal data of a certain terminal device, for example, the abnormal data generated by the terminal device 1 is not resolved, but directly and completely packaged and then transmitted to the central server.
S6, debugging and verifying abnormal data in the temporary gateway by a developer, and optimizing gateway service until the temporary gateway can adapt to the abnormal data;
S7, after the developer observes for 24-48 hours, if the analysis program can still normally run in the face of the abnormal data, the gateway service optimization is completed; otherwise, circulating S6-S7, and continuously optimizing until the optimization is completed;
S8, updating the analysis program to the gateway on the site, wherein the gateway does not specially process the data reported by the terminal equipment, at the moment, even if the terminal equipment generates abnormal data, the analysis service of the site gateway can normally process the abnormal data generated by the terminal equipment, and the abnormal data can not cause service breakdown, and after being analyzed and cleaned by the analysis service, the abnormal data enters the central server through a normal data link.
Example two
As shown in fig. 2, in this embodiment, the normal data link is: terminal equipment- > gateway (resolution) - > central server (access) - > internal data pipe- > processing service or storage service.
The exception handling data link (debug data link) is: terminal equipment- > gateway (unresolved) - > central server (access) - > interior gateway (cleaning) - > interior data pipe- > processing service or storage service.
The method of the invention transfers the abnormal data to the debugging link, and does not cause the abnormal data to influence the stability of the gateway and the stability of the normal link. The developer optimizes the gateway program in time, so that abnormal data generated by the equipment cannot influence the normal operation of the gateway, only the data link is debugged by the image, and after the analysis program is optimized and stabilized, the gateway is updated, so that the abnormal data cannot influence the stability of the gateway, and the normal operation of the gateway and the Internet of things system is ensured.
In this embodiment, the internet of things scenario is composed of a central server and a plurality of deployment sites. The set of internet of things system entities at least comprises a central server (access service, application service, data pipeline, storage service, temporary gateway, which can run multiple instances according to the need), gateway(s), terminal device(s) and related hardware (switches, routers, data communication units, traffic cards, etc.).
Deployment site a shows the normal data link flow. Deployment site B shows the debug link flow.
1. The normal data link is:
(1) The terminal devices 4, 5 transmit the collected data to the gateway.
(2) The gateway A receives and analyzes the data, cleans the data into unified standard data and transmits the unified standard data to the access service of the center server.
(3) The access service passes the data into an internal data pipe. (decoupling, peak-eliminating)
(4) Application services and storage services consume data of a data pipeline. The entire link is completed.
2. The debug data link is:
(1) The terminal device 1 collects data and transmits the data to the gateway (data with anomalies).
(2) The gateway B marks the data, does not analyze the data, marks the data and then completely transmits the data to the access service.
(3) The access service forwards the data to the temporary gateway for analysis, and if the analysis fails, the data is discarded.
(4) And if the analysis is successful, cleaning the data into unified standard data, and forwarding the unified standard data to an internal data pipeline.
(5) The application service and the storage service consume the data of the data pipeline to complete the whole link.
(6) The developer can debug the analysis service of the temporary gateway, and can easily update and replace the analysis service due to the deployment in the central server, and the analysis service on the normal link is not influenced.
(7) When the optimization is completed and abnormal data collected by the terminal equipment 1 can be normally processed, updating the analysis program of the gateway B, and returning to a normal data link at the moment.
In this embodiment, when the gateway recognizes that a certain set of data causes a program crash, the gateway tags the set of data. At this time, the group of data is directly transmitted to the temporary gateway of the central server without being parsed or cleaned at the gateway. While contacting the developer for optimization. After the repair is completed, the gateway service is updated, and at this time, even if abnormal data occurs, the stability of the gateway service is not affected, and the normal data link flow can be continued.
By adopting the technical scheme disclosed by the invention, the following beneficial effects are obtained:
