As shown in fig. 1, the system architecture includes an internet of things platform 120, a user terminal 150, and an internet of things device 140, where the internet of things platform 120 includes a plurality of internet of things servers 130 and an internet of things control center 110, the internet of things control center 110 includes a control center 111 and a database 112, the database 112 may be a data processing center of the internet of things platform 110, and an implementation terminal of the present disclosure is one of the plurality of internet of things servers 130. It can be seen that in this embodiment, the internet of things device 140 is an intelligent thermometer. When the data transmission method of the internet of things provided by the present disclosure is applied to the system architecture shown in fig. 1, a specific process may be as follows: a user accesses the control center 111 of the internet of things platform by using the user terminal 150 to register data, so as to obtain a product identifier (ProductKey), a device name (DeviceName) and a secret key (secret), and create a plurality of topics (topic) corresponding to the product identifier, the control center 111 of the internet of things platform writes the data into the database 112 for storage, and the user writes the data into the internet of things device 140 after obtaining the data; one of the internet of things servers 130 of the internet of things platform randomly sends a request for authority authentication of the internet of things devices to each internet of things device, when the internet of things device 140 receives the request, the internet of things server responds to the internet of things server, and sends three items of data including a product identifier, a device name and a timestamp and a first signature generated by using a secret key and the three items of data in a specific encryption manner to the internet of things server, the internet of things server analyzes all obtained data to obtain the product identifier, the device name, the timestamp and the first signature, then the internet of things server pulls the secret key which is stored before and corresponds to the product identifier from the database 112, encrypts the three items of data including the product identifier, the device name and the timestamp from the internet of things device 140 in the same encryption manner to obtain a second signature, when the first signature and the second signature are consistent, it is indicated that the internet of things device 140 is the owner of the product identifier sent by the internet of things device 140 and the internet of things device 140 has the secret key corresponding to the product identifier sent by the internet of things device, so that the authority authentication of the internet of things device 140 is passed, at this time, the internet of things server generates a time-efficient token (token), returns the token to the internet of things device 140, and sends the token and the product identifier to the database 112 for corresponding storage; next, the internet of things server synchronizes the token, the product identifier and the corresponding theme of the internet of things device 140 that passes the authority authentication to the memories of other internet of things servers in the plurality of internet of things servers 130 through the message queue, so that all the other internet of things servers have the ability to perform the authority verification on the internet of things device 140, when the internet of things device 140 receives a request for acquiring the acquired data from one of the other internet of things servers, the internet of things device 140 responds to the request, the token, the theme and the acquired data are returned to the requested internet of things server, the requested internet of things server determines whether the token is expired or not, then determines the product identifier corresponding to the token, further determines the theme corresponding to the product identifier, and compares the theme with the theme sent by the internet of things device 140, whether a theme consistent with the theme sent by the internet of things device 140 exists in the themes is determined, when the token is not expired and a theme consistent with the theme returned by the internet of things device 140 exists in the themes, the permission verification work on the internet of things device 140 is completed, and at this time, the internet of things device 140 is allowed to be sent to a data processing center of the internet of things platform 120 through a message queue, wherein the data processing center may be the database 112, for example. In this way, the whole process of sending the data collected by the internet of things device 140 to the internet of things platform 120 is realized.
In the related technology, tokens, themes, product identifiers and the like are all generally stored on an internet of things platform, for example, in a database of the internet of things platform, so that data acquired by internet of things equipment is acquired each time, when authority verification is performed, data (such as topic) used for verification is acquired from the internet of things platform, and a theme (topic) object is created and instantiated, so that a large amount of memory resources are occupied, the topic query efficiency is reduced, and the authority verification efficiency is further reduced due to increased time consumption for querying data from the internet of things platform; in the process, the data used for verification is synchronized into the memory of the corresponding internet of things server side, so that on one hand, a large number of theme objects do not need to be created and instantiated, and occupation of memory resources is reduced, and on the other hand, due to the fact that permission verification can be directly carried out in the memory, inquiry to an internet of things platform is not needed, inquiry time consumption is reduced, and permission verification efficiency is improved.
It should be noted that fig. 1 is only one embodiment of the disclosure, and although in the embodiment shown in fig. 1, a plurality of internet of things servers belong to an internet of things platform, data finally acquired by an internet of things device is sent to a database of the internet of things platform, the internet of things server sends the data to the internet of things platform through a message queue and one internet of things server synchronizes three items of data including a token, a product identifier and a corresponding theme with other internet of things servers, in other embodiments or specific applications, the plurality of internet of things servers may be located outside the internet of things platform, the data finally acquired by the internet of things device may be sent to any unit or module in the internet of things platform that can store data, the internet of things server may not send the data to the internet of things platform through the message queue, and one internet of things server may synchronize only two items of data including the product identifier and the corresponding theme with other internet of things servers, therefore, the present disclosure is not limited thereto, and the scope of the present disclosure should not be limited thereby.
Fig. 2 is a flowchart illustrating a data transmission method of the internet of things according to an exemplary embodiment. The internet of things data transmission method of the embodiment is executed by a first internet of things server in a plurality of internet of things servers, the first internet of things server may be a device of the same type as other internet of things servers or a device of a different type, the first internet of things server may be a server, as shown in fig. 2, and the method includes the following steps:
and step 220, receiving target data uploaded by the target Internet of things equipment.
The target data comprise internet of things data and first permission verification data, and the target data are sent by the target internet of things equipment according to a preset internet of things protocol.
The target internet of things equipment is the internet of things equipment which is used for sending data to the internet of things platform, and can be any equipment which can sense information and transmit the information, such as an intelligent desk lamp, an intelligent thermometer and the like. The action of uploading the target data by the target internet of things device can be performed by the target internet of things device actively sending the target data or by making a corresponding response according to an external request.
The preset internet of things Protocol may be any internet of things Protocol, for example, CoAP (constrained application Protocol), MQTT (Message queue Telemetry Transport Protocol), and the like.
The data of the internet of things is data generated when the target device of the internet of things runs, and for example, the data of the temperature sensed by the intelligent thermometer can be used. The first permission verification data is data used for performing permission verification on data uploaded by the target internet of things device, and may include data such as a token (token), a topic (topic), and the like.
And the second permission verification data is synchronized to the first Internet of things server side in advance by a second Internet of things server side in the plurality of Internet of things server sides.
It may be clear that at least one second permission check data is pre-stored in the memory of the first internet of things server.
In one embodiment, the at least one second permission check data is stored in a queue of the first internet of things server memory.
In one embodiment, the queue follows the principle of FIFO (First Input First Output).
In one embodiment, the at least one second permission verification data is stored in a ConcurrentHashMap of the first internet of things server memory.
The ConcurrentHashMap is a concurrency container which realizes efficient data retrieval by adopting arrays, segments, segmented locks and the like.
The embodiment has the advantages that the second authority verification data is stored in the ConcurrentHashMap, and the query time complexity of the hash is O (1), so that the query matching time is reduced, the authority verification efficiency is improved, and the system performance can be greatly improved.
Determining whether the upload of the target data is legitimate is a process of determining whether to allow the upload of the target data.
In one embodiment, the second permission verification data includes a second token, a second product identifier corresponding to the second token, and at least one second topic class corresponding to the second product identifier, and the first permission verification data includes a first token, a first product identifier, and a first topic, and the specific steps of step 230 may be as shown in fig. 3.
Fig. 3 is a detailed flowchart of step 230 according to an embodiment shown in a corresponding embodiment of fig. 2, and referring to fig. 3, the method includes the following steps:
step 230', if there is one second permission check data in the at least one second permission check data that meets the first matching condition with the first permission check data, determining that the uploading of the target data is legal, otherwise, determining that the uploading of the target data is illegal.
Wherein the first matching condition with the first permission check data is: the second token is consistent with the first token, the second product identification corresponding to the second token is consistent with the first product identification, and one second theme class corresponding to the first theme exists in at least one second theme class corresponding to the second product identification.
The at least one second permission check data may include one second permission check data, or may include a plurality of second permission check data, and for each second permission check data in the at least one second permission check data, it may be determined whether a first matching condition with the first permission check data is satisfied.
In one embodiment, the token (token) is a randomly generated character string, the product identifier (ProductKey) is a globally unique identifier issued by the internet of things platform for the product, the topic (topic) class is a set of topics (topic) corresponding to the product identifier, and the topic (topic) is a UTF-8 character string and represents a message transmission intermediary.
In one embodiment, the topic class includes a product identification parameter value, a device name parameter, and a rights portion, and the topic corresponding to the topic class includes a product identification parameter value, a device name parameter value, and a rights portion.
For example,/0 WFDSF9324JQ/$ { YourDeviceName }/user/update may be a topic class, where 0WFDSF9324JQ is a product identification parameter value corresponding to a product identification (ProductKey), $ { YourDeviceName } is a device name parameter, which corresponds to a device name, and/user/update is a rights part; the/0 WFDSF9324JQ/device1/user/update may be a topic corresponding to the topic class, wherein the device1 is a device name parameter value corresponding to a device name (DeviceName), a topic corresponds to whether the internet of things device has a right to operate on the message of the topic, and the "ADFKK 45WERJ9SOD 92" may be a token.
In one embodiment, the theme class corresponds to the theme, that is, in the case that the product identifiers are consistent, the permission part in the theme class is the same as the permission part in the theme.
For example,/0 WFDSF9324JQ/$ { YourDeviceName }/user/update is a topic class,/0 WFDSF9324JQ/device1/user/update is a topic, since the device names of the two are "0 WFDSF9324 JQ" consistent, and the rights part in the topic class and the rights part in the topic are both/user/update, i.e., the rights part in the topic class is the same as the rights part in the topic, the topic class corresponds to the topic.
In one embodiment, the second theme class includes a product identification parameter, a device name parameter, and a rights component.
For example,/$ { YourProductKey }/device1/user/update may be a second topic class.
Since the second product identification (ProductKey) is a separate part in the second rights check data, the part in the second subject class corresponding to the ProductKey can be replaced by $ { youproductkey } without losing information in the second rights check data.
In one embodiment, the second token is a character string randomly generated by the second networking service end.
In the embodiment shown in fig. 3, whether the uploading of the target data is legal is determined by matching the token, the product identifier, and the topic class stored in the memory of the first internet of things server with the token, the product identifier, and the topic in the first permission check data, and since the information required for determining whether the uploading of the target data is legal is stored in the memory of the first internet of things server in advance, it is not necessary to query or request an external terminal to obtain the information, so that the check efficiency is improved.
In one embodiment, the determining whether the uploading of the target data is legal based on at least one second permission check data and the first permission check data stored in the memory of the first internet of things server side includes:
pulling a product identifier stored in advance corresponding to the first token from an Internet of things platform;
if the second product identification and the second right verification data which are consistent with the product identification meet a second matching condition with the first right verification data, determining that the target data are uploaded legally, otherwise, determining that the target data are not uploaded legally, wherein the second matching condition with the first right verification data is as follows: and one second theme class corresponding to the first theme exists in at least one second theme class corresponding to the second product identification.
In this embodiment, the second permission verification data synchronized in advance by the second internet-of-things server only includes the second product identifier and the corresponding at least one topic class, the corresponding product identifier needs to be pulled from the internet-of-things platform during verification, and compromise is achieved between the synchronized data amount of the second internet-of-things server and verification efficiency.
And 240, if the uploading of the target data is determined to be legal, sending the internet of things data in the target data to a data processing center of an internet of things platform.
The data processing center of the platform of the internet of things can be any one or more modules or units capable of storing data in the platform of the internet of things.
When the uploading of the target data is legal, the Internet of things data can be sent to the Internet of things platform, and the Internet of things platform carries out further operations such as statistics, processing and treatment.
In one embodiment, if it is determined that the uploading of the target data is legal, sending the internet of things data in the target data to a data processing center of an internet of things platform includes:
and if the uploading of the target data is determined to be legal, sending the Internet of things data in the target data to a second message queue, and sending the Internet of things data to a data processing center of an Internet of things platform through the second message queue.
The benefit of this embodiment is that, sending data through using the message queue, has alleviated the processing pressure of the data processing center of the platform of the internet of things, has guaranteed the reliability and the stability of the platform of the internet of things.
In one embodiment, the data processing center of the internet of things platform is a Redis server of the internet of things platform.
In one embodiment, the method further comprises:
receiving a theme class updating request sent by an internet of things platform through a third message queue, wherein the theme class updating request comprises a second product identifier and at least one second updating theme class corresponding to the second product identifier, the theme class updating request is sent to the plurality of internet of things servers by the internet of things platform through the third message queue, and the second updating theme class is submitted to the internet of things platform through a user terminal by a user of a target internet of things device identified by a second product;
determining at least one second theme class corresponding to the at least one second update theme class as a second target theme class in at least one second theme class corresponding to a second product identifier in the theme class update request stored locally;
and replacing the second target theme class with a corresponding second updating theme class.
At present, because a structure tree of a theme is generally loaded through Resource when a service is initialized, a topic type that can be processed by the service cannot be changed in a service running process, and if the service needs to be restarted, service processing efficiency is reduced.
In summary, according to the data transmission method of the internet of things provided in the embodiment of fig. 2, time consumption for querying the database or the server is reduced, so that verification efficiency and data transmission efficiency of the internet of things are improved, and consumption of the memory is reduced.
Fig. 4 is a flowchart illustrating steps prior to step 230 according to one embodiment illustrated in a corresponding embodiment of fig. 2. As shown in fig. 4, the method comprises the following steps:
After the second permission verification data is obtained by the second internet-of-things server, the second internet-of-things server synchronizes to at least one internet-of-things server except the second internet-of-things server in the plurality of internet-of-things servers and is received by the first internet-of-things server as one internet-of-things server in the at least one internet-of-things server.
It should be noted that, although step 210 is located before step 220 in the present embodiment, as described in the description of fig. 4, step 210 may be performed at any step or time before step 230, such as after step 220, or even simultaneously with step 220, which is not limited by the present disclosure.
In one embodiment, the receiving the second permission check data synchronized by a second internet-of-things server of the plurality of internet-of-things servers includes:

In an embodiment, the process of the second networking service end acquiring the second permission verification data may be as shown in fig. 5. Fig. 5 is a flowchart illustrating a second networked server side acquiring second permission check data according to an exemplary embodiment, where as shown in fig. 5, the method includes the following steps:
The authority authentication data comprises a product identifier, a device name, a timestamp and a password, the password is obtained by encrypting a hash parameter by target Internet of things equipment by using a preset hash algorithm and a pre-obtained device key, the hash parameter is generated based on the product identifier, the device name and the timestamp, and the product identifier, the device name and the pre-obtained device key are generated by the Internet of things platform after a user sends a registration request to the Internet of things platform through a user terminal and are written into the target Internet of things equipment after the user obtains the product identifier, the device name and the pre-obtained device key.
Since the steps shown in fig. 5 are a process for the second networked server to obtain the second permission check data, the embodiment of fig. 5 is executed by the second networked server.
The target internet of things equipment sends the authority authentication data to the second internet of things server side, wherein the authority authentication data can be sent by the target internet of things equipment actively, or can be sent by the target internet of things equipment responding to the request of the second internet of things server side.
The predetermined hashing algorithm may include, but is not limited to, MD5, SHA-1, SHA-2, SHA-256, and the like. The hash parameter may be generated based on the product identification, the device name, and the timestamp in a variety of ways, such as the product identification, the device name, and the timestamp may be combined in a predetermined manner as the hash parameter.
