When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0043] The multi-channel data transmission method described in the preferred embodiment of the present invention is as follows: Figure 1 As shown, the multi-channel data transmission method comprises the following steps:

[0044] Step S10: pre-acquire all digital contents, set a security level for each digital content, and obtain three types of digital contents, wherein the security levels are high security level, medium security level and low security level.

[0045] Specifically, all digital content is acquired in advance, and a security level is set for each digital content, wherein the security level is high security level, medium security level and low security level, and then a security level relationship table is established according to the digital content and the security level to facilitate subsequent judgment. The digital content includes: documents, pictures, videos and voices; the documents include word documents, pdf documents and txt documents, the pictures include static pictures and dynamic pictures, the videos include mp4 videos, avi videos and mov videos, and the voices include mp3 voices and wav voices.

[0046] For example, the security level of mp4 video, avi video and mov video can be set to high, the security level of mp3 voice, wav voice, static picture and dynamic picture can be set to medium, and the security level of word document, pdf document and txt document can be set to low, thereby setting a security level for each type of digital content, and the digital content and the security level corresponding to the digital content are counted as a security level relationship table. It should be noted that the UCL logo is not used in documents and icons, but the "data content tag (DCT)" is used.

[0047] Step S20: Associating the three types of digital content with the soft bus respectively to establish multiple transmission channels.

[0048] Specifically, three transmission protocols are generated based on three security levels of digital content, and the transmission protocols include the digital content and the security level of the digital content.

[0049] Soft bus is a bus technology based on software implementation, which realizes data transmission and device communication through software protocol. Compared with hardware bus, soft bus has higher flexibility and scalability because it does not require specific hardware interface and physical connection. Soft bus can realize data exchange and communication between different computer systems and devices, for example, it can realize communication and shared resources between devices in local area network. Common soft bus protocols include TCP / IP, UDP, HTTP, FTP, etc.

[0050] In this embodiment, the process of generating three transmission protocols based on three security levels of digital content is: judging the type of the digital content, if the type of the digital content is a high security level, generating a first transmission protocol; if the type of the digital content is a medium security level, generating a second transmission protocol; if the type of the digital content is a low security level, generating a third transmission protocol; wherein the resource sizes required for data transmission by the first transmission protocol, the second transmission protocol and the third transmission protocol decrease in sequence.

[0051] It can be understood that the soft bus is a logical communication channel, and the underlying layer is a wireless communication protocol, such as mobile hotspot wifi. This logical channel shields the protocol of the underlying hardware to form a virtual logical channel. In this logical channel, the type of digital content to be transmitted is associated. Different digital content is classified and different security levels are allocated different resources and transmission protocols to establish different logical channels. When data is transmitted on the soft bus, it is necessary to package the data according to the protocol rules of the soft bus. The soft bus protocol rules include information such as data type and security level. Before sending data, the soft bus selects the allocation of resources and protocols according to the data type and security level to establish a communication channel.

[0052] Furthermore, the three transmission protocols are sent to the soft bus, and the soft bus is controlled to allocate resources of different sizes to the three transmission protocols according to the security level, and three logical transmission channels are established according to the three transmission protocols and their corresponding resources. The three logical transmission channels are respectively a high-level logical transmission channel, a medium-level logical transmission channel and a low-level logical transmission channel.

[0053] It can be understood that the three transmission protocols carry different data types and security levels respectively. The soft bus establishes three logical transmission channels according to the three different security levels, namely, a high-level logical transmission channel, a medium-level logical transmission channel and a low-level logical transmission channel. Due to the different allocation of resources, the transmission capacity and security level of each logical transmission channel are also different. It can be seen that the present invention can allocate different resources according to different digital content to form corresponding exclusive channels, so that different data types can be transmitted through different channels. This can greatly improve the transmission rate and make the transmission of the transmitted digital content in the corresponding exclusive channel path knowable and controllable.

[0054] Step S30: Obtain the business requirements to be processed, classify the digital content to be transmitted of the business requirements, and obtain a classification result.

[0055] The process of classifying the digital content to be transmitted of the business demand to obtain the classification result also includes: obtaining the authority level of the user who issued the business demand, wherein the authority level includes an administrator and a common user.

[0056] In this embodiment, the business demand actually refers to a specific application process in the system, and the application then calls the soft bus to send data. The business demand is issued by the user.

[0057] It is understandable that when a user uses an application to call the soft bus to send data, the soft bus will determine the permissions of the user and the application, and parse the type and security level of the data to be sent. In the present invention, before obtaining the type and security level of the data to be sent, the user's permissions will be determined first, that is, the user's identity will be determined.

[0058] Furthermore, after obtaining the business requirements issued by the user, the security level of the business requirements is matched according to the security level relationship table, and the digital content to be transmitted of the business requirements is classified to obtain a classification result, which is any one or more of a high security level, a medium security level and a low security level.

[0059] Step S40: Select a target channel that matches the classification result from among the multiple transmission channels, and input the digital content to be transmitted into the target channel for data transmission.

[0060] Specifically, the transmission channel is matched according to the identity of the user and the classification result. If the authority level of the user who issues the business demand is an administrator, a target channel matching the classification result is selected from the three logical transmission channels, and the digital content to be transmitted is input into the target channel for data transmission.

[0061] It can be understood that in this embodiment, the administrator, as the owner of the highest authority, can use all logical transmission channels for data transmission. Therefore, when the authority level of the user who issues the business demand is the administrator, the target channel is directly matched according to the classification result. For example, when the data type of the administrator's digital content to be transmitted is an mp4 video, the classification result at this time is a high security level. According to the high security level matching, a high-level logical transmission channel is obtained, and the digital content to be transmitted (mp4 video) is input into the high-level logical transmission channel for data transmission.

[0062] Furthermore, if the authority level of the user who issues the business demand is an ordinary user and the classification result of the digital content to be transmitted is a high security level, a medium-level logical transmission channel is selected as the target channel, and the digital content to be transmitted is input into the target channel for data transmission.

[0063] If the authority level of the user who issues the business demand is an ordinary user and the classification result of the digital content to be transmitted is not a high security level, a target channel matching the classification result is selected from the medium-level logical transmission channel and the low-level logical transmission channel, and the digital content to be transmitted is input into the target channel for data transmission.

[0064] It can be understood that in this embodiment, as an ordinary user, the ordinary user does not have the permission to use the high-level logical transmission channel (they can have the permission to use the high-level logical transmission channel after the administrator issues the permission). Therefore, when the permission level of the user who issues the business demand is an ordinary user and the classification result of the digital content to be transmitted is a high security level, the digital content to be transmitted is input into the highest level logical channel that the user can use (i.e., the medium-level logical transmission channel) by default. For example, when the data type of the digital content to be transmitted by the ordinary user is a mov video, the classification result at this time is a high security level. According to the high security level matching, the high-level logical transmission channel should be obtained. However, since the identity of the user is an ordinary user, he does not have the permission to use the high-level logical transmission channel. The ordinary user can only use the medium-level logical transmission channel and the low-level logical transmission channel. Therefore, the digital content to be transmitted (mov video) is input into the highest level logical channel (medium-level logical transmission channel) that the user can call for data transmission. If the classification result of the digital content to be transmitted is not a high security level, the target channel matching the classification result can be selected from the medium-level logical transmission channel and the low-level logical transmission channel, which will not be repeated here.

[0065] It can be seen that the present invention designs a multi-channel data transmission method, which can provide corresponding exclusive channels according to different digital contents to improve the transmission rate, and also makes the transmission of the digital content in the corresponding exclusive channel path knowable and controllable, thereby improving security, and can provide customized transmission requirements according to user needs, thereby improving user experience.

[0066] Furthermore, if Figure 2 As shown, based on the above multi-channel data transmission method, the present invention also provides a multi-channel data transmission system accordingly, wherein the multi-channel data transmission system includes:

[0067] The digital content classification module 41 is used to pre-acquire all digital content, set a security level for each digital content, and obtain three types of digital content, wherein the security levels are high security level, medium security level and low security level;

[0068] The transmission channel establishing module 42 is used to associate the three types of digital contents with the soft bus respectively to establish multiple transmission channels;

[0069] The module classification of content to be transmitted 43 is used to obtain the business requirements to be processed, classify the digital content to be transmitted of the business requirements, and obtain the classification results;

[0070] The transmission channel matching module 44 is used to select a target channel matching the classification result from the multiple transmission channels, and input the digital content to be transmitted into the target channel for data transmission.

[0071] Furthermore, if Figure 3 As shown, based on the above multi-channel data transmission method and system, the present invention also provides a terminal accordingly, and the terminal includes a processor 10, a memory 20 and a display 30. Figure 3 Only some components of the terminal are shown, but it should be understood that it is not required to implement all of the components shown, and more or fewer components may be implemented instead.

The memory 20 is used to store application software and various types of data installed in the terminal, such as the program code of the installation terminal, etc. The memory 20 may also be used to temporarily store data that has been output or is to be output. In one embodiment, a multi-channel data transmission program 40 is stored on the memory 20, and the multi-channel data transmission program 40 may be executed by the processor 10, thereby realizing the multi-channel data transmission method in the present application.

[0073] In some embodiments, the processor 10 may be a central processing unit (CPU), a microprocessor or other data processing chip, which is used to run the program code stored in the memory 20 or process data, such as executing the multi-channel data transmission method.

[0074] In some embodiments, the display 30 may be an LED display, a liquid crystal display, a touch-sensitive liquid crystal display, an OLED (Organic Light-Emitting Diode) touch device, etc. The display 30 is used to display information on the terminal and to display a visual user interface. The components 10-30 of the terminal communicate with each other via a system bus.
