Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
Example one
In the embodiment, a method for ensuring normal operation of an internet of things gateway based on data link switching is provided, and is applied to an internet of things scene, wherein the internet of things scene comprises a central server (including access service, data pipeline, processing service and storage service), a plurality of gateways (deployed in a project site, gateways A, B and c..) and a plurality of internet of things devices (devices 1, 2 and 3).
The gateway is responsible for receiving the data of the terminal equipment and forwarding the data to the access service of the central server. The same type of equipment data is completed by the same analysis program (different types of equipment load data formats are different and 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 mainly responsible for processing and storing data and providing the data for other applications to use. The access service manages multiple gateways and transmits their forwarded data to the upstream data pipe. The processing and storage services in the central server consume the data in the pipeline to complete the service function.
Temporary gateway services are also deployed in the central server, and the gateway services mainly analyze and clean data of the terminal equipment, and then merge 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 related programs of the Internet of things; the method comprises the following steps of accessing service, data pipeline, processing service, storage service, temporary gateway service and the like;
s2, the construction and operation and maintenance personnel go to each constructed site to deploy a plurality of gateways and terminal equipment; a constructor deploys the physical fixed gateway and the terminal equipment, and an operation and maintenance worker is responsible for testing whether the network and the data are normal or not, and at the moment, the scene deployment of the internet of things is completed;
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 to use;
s4, the gateway monitors whether the data of each terminal device is normal in real time, and if no abnormity is found, the gateway returns to S3; 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, the abnormal data are transferred to the temporary gateway after the access service of the central server identifies the label, and the abnormal data are analyzed in the temporary gateway; if the abnormal data of a certain terminal device causes the abnormal temporary gateway service of the central server, the data of other terminal devices cannot be influenced, and the temporary gateway service of the central server is restarted.
The gateway can label the abnormal data in multiple modes and 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, which is not analyzed, but directly and completely encapsulated and then transmitted to the central server.
S6, debugging and verifying the abnormal data in the temporary gateway by a developer, and optimizing gateway services until the temporary gateway can adapt to the abnormal data;
s7, after the developers observe for 24-48 hours, if the analysis program still can normally run in the face of the abnormal data, the gateway service optimization is finished; otherwise, circulating S6-S7, and continuously optimizing until the optimization is completed;
and S8, updating the analysis program to the on-site gateway, wherein the gateway does not specially process the data reported by the terminal equipment any more, and even if the terminal equipment has abnormal data, the analysis service of the on-site gateway can also normally process the abnormal data generated by the terminal equipment, so that the abnormal data can not cause service breakdown, and the abnormal data can enter the central server through a normal data link after being analyzed and cleaned by the analysis service.
Example two
As shown in fig. 2, in this embodiment, the normal data link is: terminal equipment- > gateway (parsing) - > central server (access) - > internal data pipeline- > processing service or storage service.
The data links for exception handling (debug data links) are: terminal equipment- > gateway (not parsing) - > central server (access) - > interior gateway (cleaning) - > interior data pipe- > processing service or storage service.
The method transfers the abnormal data to the debugging link, so that the abnormal data does not influence the stability of the gateway and the stability of the normal link. Developers optimize the gateway program in time, abnormal data generated by equipment cannot influence the normal operation of the gateway, only the image is used for debugging a data link, and when the analysis program is optimized and stabilized, the gateway is updated, so that the abnormal data cannot image the stability of the gateway, and the normal operation of the gateway and the internet of things system is ensured.
In this embodiment, the scene of the internet of things is composed of a central server and a plurality of deployment sites. A suite of internet of things system entities includes at least a central server (access service, application service, data pipe, storage service, temporary gateway, which may run multiple instances as needed), gateway(s), terminal device(s), and associated hardware (switches, routers, data communication units, traffic cards, etc.).
Deployment site a shows the normal data link flow. And the deployment site B shows the debugging link flow.
1. The normal data link is:
(1) And the terminal equipment 4 and 5 collects data and transmits the data to the gateway.
(2) And 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 central server.
(3) The access service passes data into an internal data pipe. (decoupling, peak elimination)
(4) The application service and the storage service consume data of the data pipe. 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 (the data has an exception).
(2) The gateway B marks the data, does not parse the data, and transmits the data to the access service completely after tagging the data.
(3) The access service forwards the data to the temporary gateway for resolution, and if the resolution fails, the data is discarded.
(4) If the analysis is successful, the data is cleaned into uniform standard data and forwarded to the internal data pipeline.
(5) The application service and the storage service consume data of the data pipe to complete the whole link.
(6) Developers can debug the resolution service of the temporary gateway, and the resolution service can be easily updated and replaced due to the deployment of the resolution service in the central server, and data on a normal link is not influenced.
(7) And when the optimization is completed and the abnormal data collected by the terminal equipment 1 can be normally processed, updating the analysis program of the gateway B, and returning to the normal data link.
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 data is not analyzed or cleaned at the gateway and is directly transmitted to the temporary gateway of the central server. And simultaneously, the developer is contacted to optimize the process. And after the repair is finished, updating the gateway service, wherein the stability of the gateway service is not influenced even if abnormal data occurs, and a normal data link flow can be continued.
By adopting the technical scheme disclosed by the invention, the following beneficial effects are obtained:
the invention provides a method for guaranteeing normal operation of an Internet of things gateway based on data link switching, which can reduce abnormal gateway operation caused by abnormal data, can conveniently debug and complete optimization for developers, and finally guarantees the stability of the gateway and improves the operation and maintenance efficiency.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and improvements can be made without departing from the principle of the present invention, and such modifications and improvements should also be considered within the scope of the present invention.
