In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The embodiment provides an internet of things data processing method, which can be used in an edge internet of things agent terminal in an internet of things communication system, wherein the edge internet of things agent terminal can generate a corresponding protocol client for a data terminal, and the data terminal establishes connection with a server through the communication protocol client to perform data interaction. The communication protocol in the embodiment of the application is described by taking an MQTT protocol as an example, and the edge internet of things proxy terminal may receive a connection request of an MQTT session from a data terminal. As shown in fig. 1, the data processing method of the internet of things includes:
s11: the type of the data terminal is determined.
Illustratively, there may be one or more data terminals. The data terminal type can be electric meter class terminal, can be video acquisition class terminal, can also be distribution transformer monitor terminal, also can be communication cost acquisition class terminal, and different data terminals correspond the data of different grade type, and this application embodiment does not limit the type of data terminal, and the skilled person in the art can confirm according to the in-service use needs. The same identifier can be adopted by the same type of data terminal, and the type of the data terminal can be confirmed by the edge Internet of things agent terminal according to the identifier. For example, the identifier of the electricity class terminal may be set to a, and the identifier of the video collection class terminal may be set to B, so that when the data terminal uploads the operation request, the identifier representing the type of the data terminal may be encapsulated in a message, and the edge internet of things agent terminal may determine the type of the access data terminal according to the identifier.
S12: and determining a transmission layer channel according to the type of the data terminal.
After the type of the data terminal is determined, data uploaded by the data terminal of the same type can be multiplexed to the same TCP connection channel for transmission, and data uploaded by the data terminal of the same functionality can also be multiplexed to the same TCP connection channel for transmission, for example, the data terminal of telephone charge, the data terminal of traffic charge and other communication charge data terminals of the same functionality can be multiplexed to the same TCP connection channel for transmission.
S13: and receiving an operation request and identity information uploaded by the data terminal.
For example, the operation request uploaded by the data terminal may be a data publishing request, a data subscribing request, or a data publishing and subscribing request simultaneously. The identity information of the data terminal may be any information that can be used to characterize the identity of the data terminal, such as account and password information of the data terminal. The identity information of the data terminal can be used for generating a connection request of the MQTT session of the edge Internet of things agent terminal. The embodiment of the application does not limit the type of the request information and the type of the identity information in the data request uploaded by the data terminal, and a person skilled in the art can determine the request information and the identity information according to actual use needs.
S14: and uploading the extended protocol message generated according to the operation request and the identity information to a server.
Illustratively, after the edge internet of things agent terminal determines to receive the MQTT session connection request according to the transmission layer channel connection table, the edge internet of things agent terminal establishes communication connection for the data terminal. The data terminals can be a plurality of data terminals of the same type, for example, the data terminals are all electric meter type terminals; the data terminals can also be different types of data terminals, for example, the data terminals include an electricity meter terminal, a distribution transformer monitoring terminal, a video acquisition terminal, a communication fee data terminal, and the like. For example, if the accessed data terminal may be an electric meter terminal, a corresponding communication connection is established for the electric meter terminal, and meanwhile, the identity information of the electric meter terminal, such as a user name, a password, and the like, is obtained, and a corresponding extended protocol message may be generated according to the operation request and the identity information of the electric meter terminal.
The extended protocol message can be generated by modifying a standard protocol message, the standard protocol message is a protocol generated according to the operation request data of the data terminal, and the extended protocol message can be obtained by modifying the format of the standard protocol message and adding the extended protocol message of the data terminal into the standard protocol message. Taking MQTT protocol messages as an example, a flag bit in a fixed header of the MQTT protocol message is set to characterize the type of the message, such as an extended message or a standard message, or other formed messages. And adding identity information related to the MQTT client, such as user name and password information, in a payload field of the MQTT protocol message. And supplementing and perfecting other field contents of the MQTT protocol message according to the MQTT protocol.
For example, when the subject of the packet is an extended distribution packet, setting the Quality of Service (QoS) level in the fixed header in the packet to 0x11 indicates that the packet is an extended distribution packet; and adding the user name and the password into the original subject name, and updating the subject name field in the original message variable header. If the original issuing theme of the original message is 'a/b', the original issuing theme can be updated to 'username/password/a/b' after the user name and the password are added; and updating other fields of the message according to the message format.
When the subject of the message is an extended subscription message, setting the reserved bit level in the fixed header of the subscription message to 0x0011 to indicate that the message is the extended subscription message; adding the user name and the password as a first theme filter into the payload of the original message, wherein the original theme filter is respectively 'a/b' and 'c/d', and the expanded theme filter is respectively 'user name/password', 'a/b' and 'c/d', so that the expanded user name and the expanded password are used as the first theme filter; and updating the content of other fields of the message. The extended protocol message can also be directly packaged according to the format of the extended protocol message, so that the extended protocol message contains the identity information of the MQTT client.
S15: and receiving a security authentication result of the server to the data terminal.
Illustratively, the server receives an extended protocol message processed by the edge internet of things agent terminal, where the extended protocol message includes identity information and payload information of an MQTT client, and the server may parse the extended protocol message, extract the identity information of the MQTT client in the message, that is, the identity information of the data terminal, perform security authentication of the data terminal, and transmit the security authentication result to the edge internet of things agent terminal in the form of the extended protocol message. And the edge Internet of things agent terminal can receive the extended protocol message and extract a security authentication result.
S16: and opening operation authority to the data terminal according to the operation request when the data terminal corresponding to the safety authentication result is a legal data terminal.
For example, the edge internet of things proxy terminal may determine whether the data terminal is a legal data terminal according to a security authentication result received from the server for the data terminal. When the data terminal is a legal data terminal, the edge internet of things agent terminal can extract the data operation request and the identity information of the corresponding data terminal contained in the extended protocol message according to the received extended protocol message. The edge internet of things agent terminal can open corresponding data operation authority for the data terminal according to the identity information and the operation request.
According to the data processing method of the Internet of things, the type of the data terminal is determined, the transmission layer channel is determined according to the type of the data terminal, the operation request and the identity information uploaded by the data terminal are received, the extended protocol message is generated according to the operation request and the identity information and is uploaded to the server, the security authentication result of the server on the data terminal is received, and the data operation request authority is opened for the corresponding data terminal according to the security authentication result. The method realizes that the same type of data terminals are reused to the same transmission layer channel in the communication system of the Internet of things, relieves the processing pressure on the server caused by establishing a plurality of TCP connections, saves bandwidth resources, improves the processing efficiency of the server, ensures the safety of data transmission in the communication system of the Internet of things, avoids data leakage, privacy leakage and identity misuse, and improves the safety of the communication system of the Internet of things.
As an alternative embodiment of the present application, as shown in fig. 2, before step S15, the method includes:
and S151, determining whether the data terminal accesses the transmission layer channel for the first time.
Illustratively, each data terminal has a corresponding MQTT client, the edge internet of things proxy terminal can receive a connection request of an MQTT session from the data terminal, and can judge whether the received MQTT session connection request is accessed for the first time according to a transport layer channel connection table, if the data terminal is accessed for the first time to a transport layer channel, a corresponding Transmission Control Protocol (TCP) communication connection can be established for the MQTT session, and if the data terminal is not accessed for the first time, a corresponding TCP connection port number of the data terminal is obtained for standby in subsequent data Transmission.
S152, when the data terminal is not accessed to the transmission layer channel for the first time, acquiring a connection port number of the data terminal, wherein the connection port number comprises a historical connection port number and a current connection port number.
Illustratively, if the data terminal does not access the transport layer channel for the first time, the connection port number of the data terminal may be obtained. The port number is contained in the socket information, and one port number can only correspond to one process at a time, namely, the port number and the process are in one-to-one correspondence. The port number may be a historical connection port number or a current connection port number. For example, the data terminal is a communication cost collection terminal, the port number for establishing connection when the data terminal is accessed for the first time is 1500, the port number 1500 corresponds to the traffic cost calculation process, when the communication cost data terminal is accessed to the transport layer channel again, the operation request is changed into obtaining the short message cost, the port number corresponds to the short message cost calculation process, and if the port number is 1600, the connection port number of the communication cost data terminal is 1600 at this time. And acquiring the historical connection port number and the current connection port number of the data terminal which is not accessed to the transmission layer channel for the first time so as to be convenient for the subsequent port standby when the data terminal carries out the same operation request.
S153, acquiring at least one corresponding relation among the data terminal connection port numbers, the type of the data terminal, the identity information of the data terminal and the protocol client identifier of the data terminal.
Illustratively, related information of the data terminal which is not accessed for the first time, including information of the type of the data terminal, identity information of the data terminal, and a protocol client identifier of the data terminal, etc., is stored in an existing transport layer channel connection table. When the data terminal accesses again, the port number of the data terminal is obtained, and the port number of the data terminal may be corresponded to the type of the data terminal, the identity information of the data terminal, and the protocol client identifier of the data terminal to obtain at least one corresponding relationship among the corresponding relationships.
S154, the corresponding relation is uploaded to the server.
For example, the description of the corresponding part of the above embodiment is referred to for the specific description of the corresponding relation, and the embodiments of the present application are not described herein again. After the corresponding relation between the port number of the data terminal and the type of the data terminal, the identity information of the data terminal and the protocol client identifier of the data terminal is obtained, the corresponding relation can be uploaded to a server. For the data terminal which is not accessed for the first time, the corresponding relation between the port number of the data terminal and the related information of the data terminal is obtained, the corresponding relation is uploaded to the server, the identity of the accessed data terminal can be confirmed, the potential safety hazard of identity misuse is avoided, and the safety of system data is further improved.
As an optional embodiment of the present application, before step S154, the method further includes:
first, whether the operation request is out of limit is determined according to the authority information table.
Illustratively, after the data terminal establishes MQTT session connection and accesses the transport layer channel, the corresponding authority information table may be obtained. The operation authority of the accessed data terminal can be obtained through the inquiry authority information table, and after the operation authority request is received, whether the accessed data terminal has the operation authority request or not can be inquired corresponding to the authority information table. For example, the data terminal is an electricity meter terminal, the operation authority of the data terminal may be to publish electricity meter terminal data, subscribe electricity meter terminal data, or publish and subscribe electricity meter terminal data, and when the electricity meter terminal sends an operation authority request, the edge internet of things proxy terminal may determine whether the electricity meter terminal has the operation authority request by querying the authority information table.
Secondly, when the operation authority request is out of limit, the operation request is discarded.
Illustratively, after the edge internet of things agent terminal determines that the operation permission request sent by the data terminal is out of limit by inquiring the permission information table, the operation request is discarded and is not sent to the server, so that the bandwidth resource is indirectly saved. For example, the operation authority of the electric meter terminal is to issue electric meter terminal data, when the electric meter terminal sends an operation request for obtaining communication charges, the edge internet of things agent terminal obtains that the electric meter terminal does not have the operation authority request by querying the authority information table, that is, discards the operation request.
And thirdly, when the operation authority request is not out of limit, updating the authority information table.
Illustratively, when the operation authority request sent by the data terminal is determined not to be out of limit by inquiring the authority information table, the authority information table is updated. The operation permission request is not out of limit, which may include that the permission information table does not contain the subject operation permission of the specified data terminal, indicating that the data terminal operates the subject for the first time, or may include that the operation request of the data terminal is completely matched with the permission information table, indicating that the data terminal has been authenticated and has the operation permission to the specified subject. For a detailed description of the operation authority, reference is made to the description of the corresponding part of the present embodiment, and details are not described herein again. When the operation authority request sent by the data terminal is not beyond the limit, the extended protocol message can be established to be associated with the established authority information table, and the extended protocol message is sent to the server for subsequent processing.
According to the data processing method of the Internet of things, whether the operation request sent by the data terminal exceeds the limit or not is determined by obtaining the operation request sent by the data terminal, the operation authority of the data terminal accessed to the transmission layer channel is judged and updated, the operation authority of the data terminal is perfected, potential safety hazards such as data leakage and privacy leakage are avoided, and the safety of data transmission in the communication system of the Internet of things is improved.

Illustratively, the transport layer channel connection table is composed of the identity information of the data terminal and the transport layer channels, and the identity information and the transport layer channels are in one-to-one correspondence. The method comprises the steps of inquiring a transmission layer channel connection table, determining whether a data terminal which requests to be accessed currently is accessed for the first time, determining that the data terminal is not accessed for the first time when the transmission layer channel connection table comprises the data terminal which requests to be accessed to the transmission layer channel currently, and determining that the data terminal is accessed for the first time when the transmission layer channel connection table comprises the data terminal which requests to be accessed to the transmission layer channel currently.
The method comprises the steps of determining whether a data terminal which requests to be accessed at present is accessed for the first time or not by inquiring the transmission layer channel connection table, accessing different types of data terminals into corresponding transmission layer channels by distinguishing the data terminal which is accessed for the first time and the data terminal which is not accessed for the first time, and adopting different processing modes for the data terminals with different access modes, so that the defects that the time cost is large and the processing pressure of a server is increased because the data terminals are established communication connection when the connection request of the data terminals is received are overcome.
As an optional embodiment of the present application, the data uploaded by the data terminal includes subscription request data, and after step S16, the method further includes:
