Detailed Description

For purposes of clarity and implementation of the present application, the following description will make clear and complete descriptions of exemplary implementations of the present application with reference to the accompanying drawings in which exemplary implementations of the present application are illustrated, it being apparent that the exemplary implementations described are only some, but not all, of the examples of the present application.

IOT devices: namely, the internet of things equipment such as intelligent home, sphygmomanometer, running machine, spinning and the like; the internet of things equipment cannot be directly connected with a local area network arranged at home, after the mobile phone is required to send login information of the local area network to the internet of things, the internet of things equipment can be connected, and further, the IOT equipment has communication capability with a cloud server.

As shown in fig. 1, the IOT device 11 is connected with the mobile phone 12 through bluetooth, the mobile phone 12 sends the local area network login information in the home to the IOT device 11, after the IOT device 11 logs in the local area network by using the local area network login information, the network configuration is successful, and the target IOT device 11 is connected to the cloud platform 10; then, the IOT device 11 can upload the data information collected by some sensors to the cloud platform 10 in real time through a message data transmission protocol, the cloud platform 10 pushes the device data information to the mobile phone 12 connected with the device in real time, and the mobile phone 12 can display the device data information. The process of controlling the IOT device 11 by the mobile phone 12 is that the mobile phone 12 sends a control instruction to push to the cloud platform 10, the cloud platform 10 receives the instruction and issues the instruction to the IOT device 11, and the IOT device 11 executes the instruction.

Or, the IOT device 11 is connected with the mobile phone 12 through bluetooth, the IOT device 11 sends data to the mobile phone 12 through bluetooth, and the mobile phone 12 displays the data information of the device. The mobile phone 12 sends a manipulation instruction, and the manipulation instruction is sent to the IOT device 11 through bluetooth, and the IOT device 11 executes the manipulation instruction.

However, when the television does not have the bluetooth module, the IOT device cannot complete the initial network configuration process, and thus the television cannot communicate with the target IOT device.

Based on this, the present invention provides a data communication system, as shown in connection with fig. 2, comprising: terminal 200, private server 201, display device 202, target IOT device 203;

in the data communication system, the process of sending device information to the display device 202 by the target IOT device 203 is shown in conjunction with fig. 3, and includes:

s300: the target IOT equipment transmits equipment data which is required to be transmitted to the display equipment to the terminal;

s301: if the terminal receives the device data sent by the target IOT device and determines that the target IOT device is in the device set, determining a display device corresponding to the target IOT device according to the corresponding relation between the IOT device and the display device; and sending the device data to a display device corresponding to the target IOT device through a private server corresponding to the terminal, so that the corresponding display device displays the device data to the user.

S302: and if the private server receives the device data sent by the terminal, the private server sends the device data sent by the terminal to the display device corresponding to the target IOT device.

S303: the display equipment receives equipment data sent by a private server corresponding to the terminal; and displaying the device data by adopting a display interface of the device type of the target IOT device.

Specifically, target IOT device 203 transmits device data to terminal 200 via bluetooth or a cloud platform. Specifically, referring to fig. 1, the target IOT device 203 may upload, in real time, device data collected by some sensors of itself to the cloud platform through a message data transmission protocol, and the cloud platform pushes the device data to the terminal 200 connected to the device in real time, so that the device data can be displayed on the terminal 200.

Alternatively, the target IOT device 203 is connected to the terminal 200 through bluetooth, the target IOT device 203 transmits device data to the terminal 200 through bluetooth, and the terminal 200 displays the device data. Of course, the terminal 200 may not need to display the device data, which is not particularly limited in this regard.

The terminal 200 has a function of surfing the internet, for example, using WiFi or 4G/5G, and the display device 202 may also be networked, for example, to connect to WiFi. Both the terminal 200 and the display device 202 may communicate with the private server 201 over a network;

After the terminal 200 is connected with the private server 201 through the network, the device data of the target IOT device 203 is sent to the private server 201 corresponding to the terminal 200, the private server 201 corresponding to the terminal 200 sends the device data to the display device 202 corresponding to the target IOT device 203, and the display device 202 displays the device data.

The private server 201 corresponding to the terminal 200 is a server corresponding to a non-target IOT device, is a self-established server, and may be a server specially used for communication between the target IOT device and the display device. Meanwhile, for data security, whether the equipment for transmitting data is a terminal or not can be verified, specifically, the terminal can send the own identity information to a server corresponding to the terminal, after the server corresponding to the terminal receives the equipment data sent by the terminal, whether the identity information of the terminal is the identity information transmitted before is verified, and if the identity verification is successful, the server corresponding to the terminal sends the equipment data to a display equipment corresponding to the target IOT equipment.

For data communication, there may be multiple target IOT devices desiring to communicate data with the display device. Target IOT devices such as spinning, running machines, blood glucose meters, etc. When there are multiple private servers corresponding to the terminal, the private servers that communicate with the display device may be different for each target IOT device, so that a corresponding relationship between the two private servers is established at the terminal side, and the following is combined with table 1:

TABLE 1

Target IOT devices	Private server
		Dynamic bicycle	Private servicesDevice 1
Running machine	Private server 2
		Blood glucose meter	Private server 3

The set of devices mentioned by the terminal 200 is a spinning, a running machine and a blood glucose meter, and of course, information representing the identity of each device can be recorded when each device is recorded. When the target IOT device sends device data to the terminal 200, its identity information is also sent to the terminal 200, the terminal 200 looks up the look-up table to see if it is in the device set, if so, looks up the look-up table again, finds the corresponding private server, for example, the target IOT device is a spinning, and the corresponding private server is the private server 1. Therefore, the terminal can send the device data provided by the spinning to the private server 1, and the private server 1 forwards the device data of the spinning received by the terminal.

Referring to fig. 4, a user opens a corresponding configuration interface through the terminal 200, the user inputs a target IOT device, or the user selects a IOT device that needs to configure a private server, for example, a spinning, after the selection is completed, the terminal 200 may display that the private server can be connected, and the private servers may transmit their own information to the terminal 200 in advance, when the user selects the private server 1, the terminal 200 may record a corresponding relationship, and similarly, the user may configure the private server corresponding to the treadmill as the private server 2, and the user configures the private server corresponding to the glucometer as the private server 3. The terminal 200 may store the information configured by the user, so that after receiving the information sent by the corresponding IOT device, the corresponding private server can be quickly found.

The private server may transmit what IOT device is configured at the private server, the configurator writes the corresponding relationship to the private server, and the private server transmits the information to the terminal 200, for example, the private server 1 may transmit device data of a spinning, the private server 2 may transmit device data of a running machine, and the private server 3 may transmit device data of a glucometer.

The private server for transmitting the IOT device may also have only one, and the terminal side may default to the private server to transmit the target IOT device, that is, transmit to the private server as long as the IOT device is in the device set. The present invention is not particularly limited in this regard.

For the display device displaying the device data of the target IOT device, the target IOT device may be selected on the terminal 200, and then the display device may be selected to be configured, and the display device corresponding to the target IOT device may be selected, for example, the target IOT device is a spinning, after the user selects the spinning, the corresponding display device may be selected, and the main exhibition hall television may be selected (after the selection is completed, there may be black in the selection frame).

Referring to fig. 6, when a user only selects a main exhibition hall television to display the device data transmitted by the spinning, the device data transmitted by the spinning is sent to a mobile phone (when the terminal is a mobile phone), and then the mobile phone sends the device data to a private server corresponding to the spinning, and the private server sends the device data sent by the spinning to the main exhibition hall television according to the corresponding relationship between the spinning and the main exhibition hall television, so that the main exhibition hall television displays the device data.

When the television in the main exhibition hall is displayed, images of a user riding the spinning through equipment data transmission can be displayed in combination with the motion data of the spinning. The image of the user riding the spinning and the motion data of the spinning both belong to the equipment data.

In addition to the user's selection at terminal 200, the target IOT device that needs to be data-transmitted through the terminal may also be configured to a preset display device. When only one display device can display the device data, the target IOT device can be directly configured to the preset display device without the user's own selection.

The user can select the number of the display devices corresponding to the spinning to be a plurality of. As shown in fig. 7, after the user selects the target IOT device that wants to configure, the user selects the corresponding display device, and the information of these display devices may be sent to the terminal through the private server, if the user knows the information of these display devices, the information of these display devices may also be added to the terminal, so that when the user selects, the user may select the display device. For example, the display device corresponding to the user selected spinning includes a main exhibition hall television, a exhibition hall study television, and a exhibition hall bedroom television.

When the user selects the main exhibition television, the exhibition study television and the exhibition bedroom television to display the equipment data transmitted by the spinning, the equipment data transmitted by the spinning is sent to the mobile phone (when the terminal is the mobile phone) for transfer, and then the mobile phone sends the equipment data to the private server corresponding to the spinning, and the private server sends the equipment data sent by the spinning to the main exhibition television, the exhibition study television and the exhibition bedroom television for display according to the corresponding relation between the spinning and the main exhibition television, the exhibition study television and the exhibition bedroom television.

Aiming at the display equipment corresponding to different IOT equipment selected by the user, the user can also select again, and before the user does not select the display equipment corresponding to the IOT equipment again, the last corresponding relation is adopted for data transmission.

In the process of displaying device data by the display device, the display device needs to download an application related to display, and a display screen of multiple device types can be included in the application. If the target IOT device is a spinning, the display interface display device data corresponding to the type of the spinning can be called. If the target IOT device is a treadmill, presentation interface presentation device data corresponding to the type of device of the treadmill may be invoked.

In summary, it can be known that, for each target IOT device, the private server that communicates with the display device may be different, and the display device that displays the device data of the IOT device may also be different, so that a corresponding relationship between the three devices is established at the terminal side, and the following is combined with table 2:

TABLE 2

The selection process may be as described above, and when the user or the user automatically configures the private server corresponding to the IOT device and the display device corresponding to the IOT device, the three may be formed into a relationship as shown in table 1, where each row corresponds to a correspondence between one IOT device, the private server and the display device. For example, if the terminal receives the device data of the spinning, the terminal may transmit the device data to the private server 1 based on table 2, and if the private server 1 receives the device data of the spinning sent by the terminal, the terminal may send the device data to the display device a based on table 2. After the terminal side is formed, the list can be sent to the private server, so that the private server can send the corresponding IOT device data to the corresponding display device when receiving the IOT device data.

For the above, since the correspondence between the IOT device and the display device may be formed at the terminal side, the terminal side may determine the display device corresponding to the target IOT device in advance, and send the device information of the display device corresponding to the target IOT device to the private server corresponding to the target IOT device. Therefore, the private server can directly determine the display device according to the received device information of the display device corresponding to the target IOT device, and the private server can directly transmit the device data to the corresponding display device without any change after knowing the destination to which the device data is to be transmitted.

When the corresponding relation between the IOT equipment and the display equipment is stored in the private server side, the terminal directly sends the equipment data to the corresponding private server, and the display equipment corresponding to the target IOT equipment is required to be determined according to the corresponding relation between the IOT equipment and the display equipment in the private server side. The private server can conveniently send the device data to the display device determined by the private server.

In the data transmission process, in combination with fig. 2, display device 202 may also send a control instruction to target IOT device 203, so as to control target IOT device 203.

As shown in connection with fig. 9, includes:

s900: the display equipment responds to a control instruction triggered by a user on a control interface corresponding to the equipment type, determines target IOT equipment which the display equipment wants to control according to the equipment type corresponding to the control interface, generates first control information according to the control instruction and the target IOT equipment, and sends the first control information to the terminal through a private server corresponding to the terminal.

S901: and if the private server receives the first control information sent by the display equipment, the private server sends the first control information to the terminal.

S902: and if the terminal receives the first control information sent by the private server, the terminal sends a control instruction contained in the first control information to the target IOT equipment contained in the first control information.

S903: and the target IOT equipment executes the control instruction after receiving the control instruction.

Specifically, taking the display device 202 as an example of a television, in conjunction with fig. 10, a user controls the television through a remote controller (right side of the image) to open a health application, which is an application for controlling a target IOT device, and then finds a device type for which control of the target IOT device is desired, the target application will present a control interface for the device type of the target IOT device 203, and when the target IOT device 203 is a treadmill, the user selects a control instruction to accelerate. The television then accelerates this control command and generates first control information by the target IOT device 203 and sends the first control information to the private server corresponding to the target IOT device 203.

The corresponding relationship between the target IOT device and the private server may be as shown in table 1, and after the terminal side completes setting the corresponding relationship table between the IOT device and the private server, the corresponding relationship table is transmitted to the display device through the private server. The display device may be all display devices connected to the private server. For example, if the private server 1 is connected to the display devices a to c and the private server 2 is connected to the display devices c to e, the terminal may transmit the contents of table 1 to the display devices a to c through the private server 1 and transmit the contents of table 1 to the display devices c to e through the private server 2.

When the terminal stores the corresponding table of table 2, the contents of table 2 can be transmitted to the display devices a to c, respectively, through the private server. Thus, the display devices a-c can directly query the private server corresponding to the target IOT device through table 2. For example, the display device a wants to control the spinning, and then the control instruction can be sent to the private server 1 by looking up table 2.

As shown in connection with fig. 11, includes:

s1100: the display equipment responds to a control instruction triggered by a user on a control interface corresponding to the equipment type, generates second control information according to the control instruction and the equipment type corresponding to the control interface, and sends the second control information to a private server corresponding to the terminal.

S1110: if the private server receives the second control information sent by the display device, determining a target IOT device which the display device wants to control according to the device type contained in the second control information; and generating first control information according to the target IOT equipment and the control instruction, and sending the first control information to the terminal.

S1120: and if the terminal receives the first control information sent by the private server, the terminal sends a control instruction contained in the first control information to the target IOT equipment contained in the first control information.

S1130: and the target IOT equipment executes the control instruction after receiving the control instruction.

Specifically, taking the display device 202 as a television for example, and referring to fig. 10, a user controls the television to open a target application through a remote controller, then finds a device type of the target IOT device, the target application displays a control interface of the device type of the target IOT device, and when the target IOT device is a treadmill, the user selects a control instruction to accelerate. And then the television generates second control information by accelerating the control instruction and the equipment type of the target IOT equipment and sends the second control information to a private server corresponding to the terminal, the private server corresponding to the terminal determines the target IOT equipment according to the equipment type, generates first control information and sends the first control information to the terminal.

Wherein the number of private servers corresponding to the terminal can be multiple, further judgment of the device type is required. The private server corresponding to the device type can be configured through the display device side. Referring to fig. 12, a user opens a health application, selects a device type on a setting of the health application, and then selects a private server corresponding to the device type. After the user configuration is completed, the configuration information can be stored in the display device so as to be convenient for subsequent data transmission.

The following table 3 shows:

TABLE 3 Table 3

Device type	Private server
		Treadmill type	Private server a
Bicycle type	Private server b

Of course, since the corresponding relationship between the target IOT device and the display device is stored in the private server, the private server may send the information to the display device, and the display device may modify the target IOT device into the device type corresponding to the target IOT device by modifying the corresponding relationship, so as to store the information as shown in table 2.

After the private server receives the information sent by the display device, because the private server stores the corresponding relation between the target IOT device sent by the terminal and the display device, the corresponding target IOT device can be found directly according to the device type in the second control instruction sent by the display device, so that the corresponding relation is queried, and the target IOT device that the display device wants to control can be directly determined. And then the target IOT device and the control command are sent to the terminal. After receiving the information sent by the private server, the terminal sends a control instruction to the target IOT device, so that the function of controlling the target IOT device by the display device can be realized.

For example, since the terminal and the display device are connected to the private server through the network, in order to protect the security of data transmission, the invention proposes that the device data is encrypted by adopting the target key agreed by the display device corresponding to the target IOT device, and the encrypted device data is sent to the display device corresponding to the target IOT device through the private server corresponding to the terminal;

The target secret key is determined according to public character strings agreed by private servers corresponding to the terminal and the target IOT equipment, private character strings generated by the terminal and private character strings generated by the private servers corresponding to the target IOT equipment.

Specifically, the encryption mode can be AES symmetric encryption, and the reason for the selection is that the encryption mode is high in safety, very fast in encryption speed and high in efficiency, and is suitable for occasions where data are frequently transmitted in real time. The key exchange adopts DH key exchange, which has the function of enabling the communication parties to create the same key in an unsafe channel, generating the same key by exchanging public keys between the client and the server, and taking the key as the key of the symmetric encryption algorithm to achieve the purpose of enabling the key of the symmetric encryption algorithm to be dynamically modified. This improves the security of data transmission over the network. The key exchange process of the invention is as follows:

1. a terminal (hereinafter abbreviated as a) a and a display device (hereinafter abbreviated as B) B agree with an initial number g such as g=5 and a prime number p such as p=23, g and p being disclosed;

a generates a random number a, a being a secret private key, e.g. a=6;

a calculates ga% p to send to B, ga% p=56v23=8;

B generates a random number b, b being a secret private key, such as b=15;

b calculates gB% p to be sent to A, gB% p=5≡15% 23=19;

after receiving gb% p, A calculates (gb% p)/(a% p=196% 23=2 by using the private key a;

b receives the gA% p, then uses the private key b to calculate (gA% p), b% p=815% 23=2;

8. thus both parties a and B obtain one and the same key K:2;

in the whole communication process, g, p, ga% p and gb% p are disclosed, and at the moment, a is difficult to obtain through g, p and ga% p, and b is difficult to obtain through g, p and gb% p, so that the final secret key is safer.

And finally, the two ends encrypt and decrypt the data by taking the secret key K as a symmetric encryption secret key.

Of course, the above encrypted content is performed in the private server without changing the data content transmitted to the display device by the terminal, and the key may be agreed at both ends of the terminal and the display device according to the above scheme, so that the private server directly forwards the encrypted content. Referring to fig. 13, after receiving device data sent by a target IOT device, a terminal uses a secret key K (i.e., a target secret key) to obtain ciphertext C through an AES encryption function, sends the ciphertext C to a display device through a private server, and the display device can decrypt the ciphertext C obtained by the AES encryption function using the secret key K, and then obtains decrypted plaintext P, i.e., device data.

Before the terminal and the display equipment are connected, a private server can be adopted for connection, and the embodiment of the invention also provides a socket communication connection. Specifically, the terminal integrated device sdk is connected with the device, and a socket communication service is introduced to realize two-way communication between the terminal and two ends of the display device, one serving as a service end and one serving as a client end. Referring to fig. 14, the specific implementation procedure is as follows:

1. the display equipment is used as a Socket server, and a Port is opened to receive the message content sent by the terminal;

2. on one hand, the terminal integrates the SDK of the IOT equipment to realize the data interaction between the original IOT equipment and the cloud platform; on the other hand, a Socket client is integrated, and the address and the port of the display device (namely the IP address and the open port of the display device) are connected to establish a data receiving and transmitting channel with the display device;

3. when the terminal receives the device data pushed by the device cloud platform, the socket service can be called, and the received device data from the device cloud platform is sent to the connected display device;

4. the display device can receive the device data sent by the IOT device and perform interface display;

5. When the display equipment is to control the IOT equipment, the display equipment sends instruction information to the terminal;

6. the terminal receives an instruction sent by the display device and sends an operation instruction to the cloud hungry platform of the IOT device;

7. the cloud platform of the IOT equipment receives the operation instruction and sends the operation instruction to the IOT equipment;

8. and the IOT equipment receives the instruction and executes the corresponding command.
