Step S102, obtaining identification information of a second interactive terminal based on the first data information;

In this embodiment, the network Address is specifically an IP Address (Internet Protocol Address).
Step S104, the second data information needing to be analyzed is sent to the second interactive terminal based on the network address of the second interactive terminal.
In this embodiment, after the network address of the second interactive terminal is obtained, the second data information may be sent to the second interactive terminal based on the network address, or the entire data packet may be sent to the second interactive terminal, so that the second interactive terminal analyzes the second data information to obtain the target data content.
In this embodiment, the identification information of the second interactive terminal is set in the first data information that does not need to be analyzed, so that after the data packet is obtained by the data exchange center of the internet of things, the identification information of the second interactive terminal can be directly obtained from the first data information in the data packet without analyzing the data packet, and then the corresponding IP address is found according to the identification information, and then the data packet is forwarded to the corresponding interactive terminal.

In this embodiment, the IP address of the second interactive terminal is obtained by directly analyzing the second data information, which can ensure that the data packet is forwarded in time, so that the second interactive terminal can obtain the corresponding data information in time to complete data transmission. Or, in this embodiment, under the condition that the identification information of the second interactive terminal cannot be obtained from the first data information, a prompt message may be fed back to the first interactive terminal, so that the first interactive terminal retransmits the data packet containing the identification information of the second interactive terminal, thereby ensuring normal transmission of data.

The identification information in this step may be generated in advance based on the characteristic information of the interactive terminal itself, or may be allocated to the interactive terminal in advance based on a predetermined rule.
Step S203, obtaining the identity information of the first interactive terminal from the first data information;
in this step, the Identity information is used to uniquely identify the Identity of the interactive terminal, and may specifically be an Identity document (Identity identification number) of the interactive terminal. In a specific implementation process, the embodiment may allocate a corresponding enterprise ID to each enterprise in advance based on a preset rule, and then generate a device ID of the interactive terminal based on the enterprise ID to which each terminal device belongs and feature information of the interactive terminal itself, or allocate a corresponding device ID to each interactive device of each enterprise according to a preset matching relationship of device IDs under the same enterprise.
Step S204, determining the identity information of the second interactive terminal based on the identification information of the second interactive terminal;
in the specific implementation process in this step, after obtaining the identification information of the second interactive terminal, it may be specifically determined that the identity information corresponding to the identification information is the identity information of the second interactive terminal based on a correspondence relationship between the identification information of the terminal and the identity information that is established in advance.
Step S205, determining the network address of the second interactive terminal based on the identification information of the second interactive terminal and the pre-established corresponding relationship between the identification information of the terminal and the network address;
step S206, determining whether the identity information of the first interactive terminal and the identity information of the second interactive terminal meet a matching relationship;
in the specific implementation process of this step, after the IP address of the second interactive terminal, the identity information of the second interactive terminal, and the identity information of the first interactive terminal are obtained, it may be determined whether the first interactive terminal and the second interactive terminal have a preset matching relationship based on the identity information of the first interactive terminal and the identity information of the second interactive terminal, that is, whether the first interactive terminal and the second interactive terminal belong to terminals in the same enterprise, specifically, whether the first interactive terminal and the second interactive terminal belong to the same enterprise may be determined according to device IDs of the first interactive terminal and the second interactive terminal, and then it may be determined whether the first interactive terminal and.
Step S207, under the condition that it is determined that the identity information of the first interactive terminal matches the identity information of the second interactive terminal, sending the second data information to the second interactive terminal based on the network address.
In this step, when it is determined that the identity information of the first interactive terminal and the identity information of the second interactive terminal match, it is determined that the first interactive terminal and the second interactive terminal belong to the same enterprise and satisfy the data transmission condition, and then the second data information can be sent to the second interactive terminal based on the IP address of the second interactive terminal, and certainly, the whole data packet can also be sent to the second interactive terminal.
In this embodiment, before sending the second data information, it is determined whether the first interactive terminal and the second interactive terminal belong to the same enterprise, and data sending is performed under the condition that the first interactive terminal and the second interactive terminal belong to the same enterprise, so as to ensure the security of the data information.
Another embodiment of the present application provides a data transmission method, as shown in fig. 3, including the following steps:
step S301, acquiring the corresponding relation among the identity information, the equipment type and the network address of the terminal; and constructing a mapping table based on the corresponding relation.
In the specific implementation process of this step, a communication relationship between the first interactive terminal and the second interactive terminal may be established first, and then the identity information, the device type, and the network address reported by the first interactive terminal and the second interactive terminal are received to obtain the corresponding relationship; of course, the identity information, the identification code, and the network address reported by the first interactive terminal and the second interactive terminal may also be received to obtain the corresponding relationship, so as to construct the mapping table. Therefore, when the identification information is subsequently acquired from the first data information of the data packet, the identity information and the IP address of the second interactive terminal can be determined according to the identification code by acquiring the identification code.
Step S302, a data packet sent by a first interactive terminal is obtained; the data packet comprises first data information which does not need to be analyzed and second data information which needs to be analyzed;
step S303, obtaining the equipment type of the second interactive terminal based on the first data information;
step S304, obtaining the identity information of the first interactive terminal from the first data information;
step S305, searching a mapping table which is established in advance and stores the corresponding relation between the equipment type and the identity information based on the equipment type of the second interactive terminal so as to determine that the identity information corresponding to the equipment type of the second terminal is the identity information of the second interactive terminal;
step S306, searching a mapping table which is established in advance and stores the corresponding relation between the equipment type and the IP address based on the equipment type of the second interactive terminal so as to determine that the IP address corresponding to the equipment type of the second terminal is the IP address of the second interactive terminal;
step S307, determining whether the identity information of the first interactive terminal and the identity information of the second interactive terminal meet a matching relationship;
step S308, under the condition that the identity information of the first interactive terminal is determined to be matched with the identity information of the second interactive terminal, the second data information is sent to the second interactive terminal based on the IP address.
In the embodiment, the communication relationship with each interactive terminal is established in advance, and then the identity information, the network address and the identification information such as the equipment type, the identification code and the like reported by each interactive terminal are received, so that the corresponding relationship among the identity information, the identification information and the network address is obtained, and the mapping table is constructed, thereby laying a foundation for quickly searching the corresponding identity information and the corresponding network address according to the identification information in the following, being beneficial to quickly determining the network address and improving the data transmission efficiency.
In this embodiment, the corresponding relationship between the device type and the network address of each interactive terminal is stored in the data center (cloud platform) of the internet of things, so that when data transmission is required, the data center of the internet of things can search the network address of the second interactive terminal according to the device type of the second interactive terminal in the data packet sent by the first interactive terminal, and further forward the data packet to the second interactive terminal. The data exchange center of the internet of things directly acquires the device type of the second interactive terminal from the data packet, so that the data exchange center of the internet of things does not need to analyze the data packet, does not need to know a data message, does not need to acquire a data encryption mode and a key, and does not need to store data, thereby ensuring the safety of data and preventing data leakage.
The application further provides a data transmission method applied to the first interactive terminal. In this embodiment, the first interactive terminal is in communication connection with the data switching center to send the data packet to the data switching center, and then forward the data packet to the target interactive terminal through the data switching center. As shown in fig. 4, the data transmission method in this embodiment includes the following steps:
step S401, establishing a communication relation with an Internet of things data center;
in this step, as shown in fig. 5, in the case that the first interactive terminal belongs to the local network device, the internet of things data switching center may be accessed through the wide area network device, that is, through the gateway (gateway). The wan portion of the gateway may be LTE (Long Term Evolution), 5G (5th generation mobile networks), NB-IOT (Narrow Band Internet of Things), WIFI (wireless Internet access), or LAN (Local Area Network).
If the first interactive device is a wide area network device, the IOT data exchange center can be directly accessed; the data exchange center itself in this embodiment has a static IP, so the first interactive terminal can find and connect with the data exchange center in a short connection COAP (Constrained Application Protocol) and a long connection MQTT (Message queue Telemetry Transport Protocol).
Step S402, sending a data packet to the Internet of things data center, and forwarding second data information needing to be analyzed in the data packet to a second interactive terminal based on the identification information in the first data information needing not to be analyzed in the data packet by the Internet of things data center.
In this step, before the first interactive terminal sends the data packet, the method further includes: and generating a data packet to be transmitted in a predetermined mode or format, so that the data packet contains first data information which does not need to be analyzed and second data information which needs to be analyzed. The first data information in this embodiment is in the form of plaintext, which does not involve sensitive and private information, and therefore can be obtained by the data switching center without worrying about being leaked. The second data information exists in a non-plaintext form, that is, the second data information needs to be analyzed to obtain specific data content in the second data information, which may be information related to sensitivity and privacy and target data information to be obtained by a second interactive user, and only the target interactive user has a corresponding analysis mode and can analyze the second data information.
Specifically, the data packet to be forwarded may be generated according to a data packet format as shown in fig. 6: the data packet includes a header and payload1 (valid data 1), where the valid data 1 includes: vendor ID (Enterprise identity number), Device type (Device type), Device ID (Device identification number), payload2 (valid data), and CRC (Cyclic redundancy check). In this example, the first data information is composed of a vendor ID (enterprise identity identification number), a Device type (Device type), and a Device ID (Device identification number), where the Device ID is specifically an ID of the first interactive terminal, and the Device type is a Device type of the second interactive terminal. The second data information includes payload2 (valid data) and CRC (cyclic redundancy check). The vendor ID (enterprise identity number), Device type (Device type), and Device ID (Device identification number) may also be encapsulated in the second data information during the implementation.
In a specific implementation process of this embodiment, the identification information, the identity information, and the network address of the first interactive terminal may also be sent to the data exchange center in advance, so that the data exchange center constructs the mapping table according to the identification information, the identity information, and the network address. When the first interactive terminal generates a data packet to be sent subsequently, only the identification information of the second interactive user can be encapsulated in the first data information in a plaintext form, and the identity information of the first interactive user is encapsulated in the first data information in a plaintext form. Therefore, after the data exchange center obtains the data packet, the identification information of the second interactive user and the identity information of the first interactive user can be obtained without analysis, then the corresponding IP address and the identity information of the second interactive user are searched according to the identification information of the second interactive user, and under the condition that the identity information of the second interactive user is matched with the identity information of the first interactive user, the second data information is sent to the second interactive user based on the determined IP address.

Of course, the data transmission apparatus in this example may further include a feedback module, configured to feed back prompt information to the first interactive terminal under the condition that the identification information of the second interactive terminal cannot be obtained from the first data information, so that the first interactive terminal retransmits the data packet including the identification information of the second interactive terminal.

the sending module is used for sending a data packet to the internet of things data center so as to forward second data information needing to be analyzed in the data packet to a second interactive terminal based on the identification information in the first data information needing not to be analyzed in the data packet by the internet of things data center.
In a specific implementation process of this embodiment, the present embodiment further includes a generating module, where the generating module is configured to generate a data packet to be sent in a predetermined manner or format, so that the data packet includes first data information that does not need to be analyzed and second data information that needs to be analyzed. The first data information in this embodiment is in the form of plaintext, which does not involve sensitive and private information, and therefore can be obtained by the data switching center without worrying about being leaked. The second data information exists in a non-plaintext form, that is, the second data information needs to be analyzed to obtain specific data content in the second data information, which may be information related to sensitivity and privacy and target data information to be obtained by a second interactive user, and only the target interactive user has a corresponding analysis mode and can analyze the second data information.
In a specific implementation process of this embodiment, the sending module is further configured to send the identification information, the identity information, and the network address of the first interactive terminal to the data exchange center in advance, so that the data exchange center constructs the mapping table according to the identification information, the identity information, and the network address. When the first interactive terminal generates a data packet to be sent subsequently, only the identification information of the second interactive user can be encapsulated in the first data information in a plaintext form, and the identity information of the first interactive user is encapsulated in the first data information in a plaintext form. Therefore, after the data exchange center obtains the data packet, the identification information of the second interactive user and the identity information of the first interactive user can be obtained without analysis, then the corresponding IP address and the identity information of the second interactive user are searched according to the identification information of the second interactive user, and under the condition that the identity information of the second interactive user is matched with the identity information of the first interactive user, the second data information is sent to the second interactive user based on the determined IP address.
The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present application and such modifications and equivalents should also be considered to be within the scope of the present application.
