In the embodiment of the present invention, specifically, the access gateway detects whether the target internet of things data sent by the target internet of things device is received according to the detection instruction, and when the detection result of step 101 is no, step 101 may be continuously executed.

Optionally, the detection instruction may be an artificial trigger detection instruction or a timing trigger detection instruction, which is not limited in the embodiment of the present invention. Further optionally, the timing trigger detection instruction is a trigger detection instruction for each time a set time length passes, where the set time length may be any time interval, or may be a continuous trigger detection instruction without a time interval.

102. When detecting that the target internet of things data sent by the target internet of things equipment is received, the access gateway judges whether a target protocol matched with the target internet of things equipment exists in a pre-stored protocol library.

In the embodiment of the present invention, optionally, the target protocol may be a protocol paired with a target internet of things device, or may be a protocol paired with a different manufacturer and/or a different device type and/or a different lot of internet of things device produced by the same manufacturer, where the protocol is applicable to the target internet of things device, and the embodiment of the present invention is not limited.

103. When judging that a target protocol matched with the target internet of things equipment exists in a pre-stored protocol library, the access gateway invokes the target protocol to execute data analysis operation on the target internet of things data, and a data analysis result is obtained.

In the embodiment of the invention, specifically, an access gateway acquires a target protocol matched with target internet of things equipment from a protocol library, and analyzes data analysis operation on the target internet of things data by combining the target protocol and a data communication protocol of the target protocol; optionally, there may be a plurality of sub-protocol libraries in the protocol library, and the target protocol may be stored in at least one sub-protocol library in the protocol library.

104. And the access gateway performs encapsulation operation on the data analysis result according to a predetermined data encapsulation format to obtain a data encapsulation result.

In the embodiment of the invention, specifically, the access gateway analyzes the data analysis result, repackages the data analysis result into a fixed header, a variable header and a message body according to the MQTT protocol specification, and obtains the data encapsulation result in the standard data encapsulation format.

105. And the access gateway sends a data encapsulation result to the Internet of things platform.

In the embodiment of the invention, specifically, after the access gateway obtains the data encapsulation result, the data encapsulation result can be sent to the internet of things platform according to the set sending time length between the obtained data encapsulation result and the sent data encapsulation result; optionally, the sending duration may be any time interval, or may be no time interval, that is, the data packaging result is immediately sent to the platform of the internet of things after the data packaging result is obtained.

Therefore, the internet of things device access method based on the multi-protocol adaptation described by the embodiment of the invention can uniformly encapsulate different internet of things device protocols, analyze and encapsulate the internet of things data in combination with the encapsulation protocol, acquire a data encapsulation result and send the data encapsulation result to the internet of things platform so as to finish data docking between the internet of things device and the internet of things platform, thereby being beneficial to solving the problems of large research and development difficulty and complicated steps for realizing data docking between the internet of things device and the internet of things platform caused by a plurality of protocols of the internet of things device and large adaptation difficulty, improving the possibility of successfully completing data docking between different internet of things device and the internet of things platform, and further improving the efficiency of data docking and the expandability of a system.

In an optional embodiment, the internet of things device access method based on the multi-protocol adaptation may further include the following operations:

when judging that a target protocol matched with the target internet of things equipment does not exist in a pre-stored protocol library, the access gateway outputs a protocol adding prompt, wherein the protocol adding prompt is used for prompting a corresponding operator to add the target protocol into the protocol library; or,

when judging that the pre-stored protocol library does not have the target protocol matched with the target internet of things equipment, the access gateway sends a protocol acquisition request to the cloud server, wherein the protocol acquisition request comprises a protocol identifier of the target protocol and is used for requesting the cloud server to send the target protocol to the access gateway.

In the embodiment of the invention, optionally, after the access gateway outputs the protocol adding prompt, the access gateway detects whether the protocol library has added the target protocol at regular time, and when detecting that the protocol library has not added the target protocol, outputs the protocol adding prompt again, and the regular detection duration can be set to any duration according to the requirement; further optionally, the access gateway records the number of protocol addition prompts output for the target protocol, and when the number of protocol addition prompts output is greater than or equal to a set threshold and the target protocol is not yet added in the protocol library, stops detecting whether the target protocol is added in the protocol library and stops outputting the protocol addition prompts.

Therefore, the optional embodiment can provide various modes for prompting and completing the operation of adding the protocol to the protocol library, improves the selectivity of the mode of adding the protocol to the protocol library and the convenience of carrying out the protocol adding operation, is beneficial to better completing the operation of carrying out data analysis on the internet of things data by combining the protocol, and further improves the efficiency of completing the data docking operation between the internet of things equipment and the internet of things platform.

In another optional embodiment, the protocol library includes a first sub-protocol library and a second sub-protocol library, all protocols included in the first sub-protocol library meet a predetermined first call condition, and all protocols included in the second sub-protocol library do not meet the first call condition; further, in step 102, the determining, by the access gateway, whether a target protocol matched with the target internet of things device exists in a pre-stored protocol library may include:

the access gateway judges whether a target protocol matched with target internet of things equipment exists in a first sub-protocol library included in a pre-stored protocol library;

if the second sub-protocol library included in the pre-stored protocol library is judged to have the target protocol matched with the target internet of things equipment, the access gateway determines that the target protocol exists in the protocol library;

if the second sub-protocol library included in the pre-stored protocol library is judged to not have the target protocol matched with the target internet of things device, the access gateway determines that the target protocol does not exist in the protocol library.

In the embodiment of the present invention, optionally, the target protocol may be a pairing protocol of other internet of things devices adapted to the target internet of things device, or may be a pairing protocol of the target internet of things device.

Therefore, the optional embodiment sets the sequence of searching the matching protocol operation in the protocol library, so that the searching operation of the matching protocol is more targeted, the searching time is reduced, the matching protocol can be more quickly searched, and the efficiency of completing the data analysis operation and the data encapsulation operation of the internet data is further improved.

In yet another optional embodiment, the internet of things device access method based on multi-protocol adaptation may further include the following operations:

when a target protocol matched with the target internet of things equipment exists in the second sub-protocol library, the access gateway judges whether the target protocol meets a first predetermined call condition or not;

when the target protocol is judged to meet the first calling condition determined in advance, the access gateway moves the target protocol from the second sub-protocol library to the first sub-protocol library;

when the target protocol is judged not to meet the first calling condition, the access gateway judges whether the target protocol meets the second calling condition which is determined in advance;

and when the target protocol is judged to meet the second calling condition, the access gateway deletes the target protocol from the second protocol library.

In the embodiment of the invention, optionally, when the target protocol which does not meet the first call condition is judged to be not met, and the second call condition is not met, the target protocol is continuously stored in the second sub-protocol library;

specifically, the step of meeting the first call condition means that the number of times that a certain protocol is called within a specified time interval threshold is greater than or equal to a set common threshold, the access gateway determines the protocol meeting the first call condition as a common protocol and stores the common protocol into a first sub-protocol library; the fact that the first calling condition is not met means that the number of times that a certain protocol is called within a specified time interval threshold is smaller than a set common threshold, the access gateway determines the protocol which does not meet the first calling condition as an unusual protocol and stores the unusual protocol into a second sub-protocol library; meeting the second call condition means that the number of times that a certain protocol is called in a specified time interval threshold is smaller than a set deletion threshold, and the access gateway deletes the protocol meeting the second call condition from the protocol library;

Optionally, the specified time interval threshold may be set to any duration according to a specific requirement, the setting common threshold may be set to any value according to a specific requirement, and the setting deletion threshold may be set to any value according to a specific requirement.
