[0035] Embodiment one

[0036] Figure 1 A flow chart of a data transmission method provided for the embodiment one of the application, the embodiment can be applicable to the case that different types of service flows are configured according to dedicated bandwidth and shared bandwidth respectively, the method can be executed by the data transmission device in any embodiment of the application, the data transmission device can be realized in the form of hardware and / or software, and the data transmission device can be configured in a USB host (i.e. Host end), as shown in the figure, the method comprises: Figure 1

[0037] S101, in response to obtaining the to-be-transmitted data, configuring the first service flow with a receiving object being a first type device in the to-be-transmitted data in a corresponding dedicated bandwidth; wherein the dedicated bandwidth is matched with the first type device one by one.

[0038] The USB host and the USB slave are connected through a USB interface, and the USB interface is pre-divided into dedicated bandwidth and shared bandwidth; wherein the dedicated bandwidth is the bandwidth specially used by a certain first type device, and no matter whether it is a second type device or other first type device, none of them has the use right of the bandwidth; the dedicated bandwidth is matched with the first type device one by one, that is, each dedicated bandwidth only provides data transmission service for one first type device, and each first type device can only transmit data through one dedicated bandwidth.

[0039] According to the USB Stream protocol, the host allocates one kind of service flow for each first type device and second type device, at the same time, the host calculates the specific bandwidth value occupied by the dedicated bandwidth corresponding to the current first type device according to its transmission rate; for example, 256KB of dedicated bandwidth is allocated for the sound device in the first type device; 512KB of dedicated bandwidth is allocated for the microphone device in the second type device; the bandwidth value occupied by the dedicated bandwidth is always reserved for the first type device to use at any time, so as to ensure the real-time performance of the first type device in data transmission. ​

[0040] The first type device can be pre-configured according to the specific application scenario of the USB host and the USB slave, for example, in the smart security scenario, the camera, the video recorder and the alarm and the like can be defined as the first type device; in the smart furniture scenario, the fresh air system, the smart induction lamp and the smart television and the like can be defined as the first type device; in the smart office scenario, the printer, the scanner and the fax machine and the like can be defined as the first type device.

[0041] In particular, in order to ensure that the service flow matches the external device, the bandwidth in the USB interface can be pre-divided, for example, the first 256KB matches the first type device A, the second 256KB matches the first type device B, and the third 256KB matches the first type device C; when the first type device A and the first type device C exist in the current transmission data, the corresponding service flow is configured in the first 256KB and the third 256KB respectively, and the data in the second 256KB is kept empty, for example, the value of each digit in the second 256KB is 0; in this way, the USB slave can confirm which first type device the service flow in the current transmission data includes according to the distribution position of the service flow.

[0042] Accordingly, when the USB host obtains the to-be-transmitted data through the host computer or other devices, the service flow in the to-be-transmitted data is parsed and obtained, the service flow may include one or more service flows of the first type device, that is, the first service flow, each first service flow is matched with the corresponding dedicated bandwidth, and the first service flow is sent to the USB slave through the dedicated bandwidth; and the dedicated channel without the first service flow is kept empty.

[0043] Optionally, in the embodiment of the application, the first service flow of the first type device in the to-be-transmitted data is configured in the corresponding dedicated bandwidth, including: the first service flow and the device identifier of the first type device are configured in the corresponding dedicated bandwidth. Specifically, after the first service flow is obtained, the device identifier of the corresponding first type device can be added to each first service flow, so that the first service flow sent by the USB host is actually a combination mode of “device identifier+first service flow”.

[0044] The USB slave can determine which external device the current service flow belongs to according to the device identifier after obtaining the transmission data, and can also determine the corresponding bandwidth value of the external device according to the device identifier, and then send the data of the specified number of bits after the device identifier to the external device. Therefore, the USB host does not need to configure null data when configuring transmission data, and does not need to configure according to the bandwidth position, can sequentially connect each first service flow, and distinguish through the device identifier, which not only ensures the ordered transmission of the first service flow, but also reduces the configuration complexity of the transmission data and improves the data transmission efficiency.

[0045] S102, the second service flow with the second type device as the receiving object in the to-be-transmitted data is configured in the shared bandwidth; wherein the priority of the first type device is higher than that of the second type device.

[0046] The second type device is an external device with low real-time requirement for data transmission, and the priority thereof is lower than that of the first type device. Unlike the first type device, the service flow of the second type device does not have a dedicated bandwidth, but all service flows of the second type device share the shared bandwidth, and the second service flow with current transmission demand is configured in the shared bandwidth. Therefore, even if a new second type device is added to cause data bandwidth overflow in the shared bandwidth, the dedicated bandwidth of the first type device is not affected.

[0047] In particular, since multiple second service flows share the shared bandwidth, each second service flow does not have a fixed data position, and therefore the USB host needs to add a corresponding device identifier to each second service flow, so that the USB slave can directly obtain the corresponding second service flow according to the parsed device identifier. Similarly, after obtaining the transmission data, the USB slave can determine which second type device the current second service flow belongs to according to the device identifier, and can also determine the corresponding bandwidth value of the device according to the device identifier, and then send the data of the specified number of bits after the device identifier to the external device.

[0048] If the number of second service flows to be sent at the current time is too large, and the shared bandwidth cannot meet the transmission demand of all second service flows, the above-mentioned part of the second service flows can be configured in the shared bandwidth, and then the remaining second service flows can be sent after a transmission period, so as to realize the delayed transmission of part of the transmission data in the case that multiple second service flows exceed the transmission bandwidth of the USB interface, and ensure the ordered transmission of the second service flow.

[0049] Optionally, in the embodiments of the present application, the second type of devices includes instant devices and time-consuming devices, and the priority of the instant devices is higher than that of the time-consuming devices. Specifically, the instant devices refer to external devices with short communication time and no need for the USB interface to continuously transmit data, such as smart lamp devices, smart refrigerator devices, and printers, etc.; the time-consuming devices refer to external devices with long communication time and need for the USB interface to continuously transmit data, and in general, the USB interface needs to continuously transmit data as long as the host computer of the USB host is not closed, such as cameras, speakers, and microphones, etc.; the instant devices and the time-consuming devices can be pre-planned and each external device is configured with a corresponding device category.

[0050] In addition, the USB host can also classify the second type of devices according to the data transmission amount or the data transmission frequency of each second type of device in the past period of time, if the data transmission amount is greater than a preset data threshold or the data transmission frequency is greater than a preset frequency threshold, it is determined that the current second type of device is a time-consuming device; if the data transmission amount is less than or equal to the preset data threshold or the data transmission frequency is less than or equal to the preset frequency threshold, it is determined that the current second type of device is an instant device.

[0051] If the current second service flow is a service flow of a time-consuming device, if the current shared bandwidth cannot bear the transmission of the second service flow, the second service flow is configured in the shared bandwidth after the communication of the second type of device in communication is completed; if the current shared bandwidth can bear the transmission of the second service flow, the second service flow is directly configured in the shared bandwidth.

[0052] If the current second service flow is a service flow of an instant device, if the current shared bandwidth cannot bear the transmission of the second service flow, it is judged whether there is a time-consuming device in communication.

[0053] S103, the to-be-transmitted data is sent to the slave through the dedicated bandwidth and the shared bandwidth, so as to send the first service flow to the corresponding first type of device through the slave and send the second service flow to the corresponding second type of device through the slave.

[0054] The USB host sends the data to be transmitted to the USB slave through the USB interface, and the USB slave determines the correspondence between the first service flow and the first type of device according to the distribution position of the first service flow in the dedicated bandwidth or the device identifier in the first service flow, and then sends the first service flow to the corresponding external device; the USB slave determines the correspondence between the second service flow and the second type of device according to the device identifier of the second service flow in the shared bandwidth, and then sends the second service flow to the corresponding external device, thereby completing the data transmission between the USB host and the USB slave.

[0055] The technical scheme of the embodiment of the application configures the first service flow with the first type of device as the receiving object in the data to be transmitted in the corresponding dedicated bandwidth, configures the second service flow with the second type of device as the receiving object in the shared bandwidth, and finally sends the first service flow to the corresponding first type of device through the dedicated bandwidth and the shared bandwidth, and sends the second service flow to the corresponding second type of device. Therefore, not only is the real-time data transmission between the host and the plurality of external devices realized, but also the defect of defining various data packets through software protocols to control different external devices is avoided, the communication difficulty between the host and the slave is reduced, the resource consumption amount in the data transmission process is reduced, and in addition, when the service flow exceeds the bandwidth, the data of the specified type of device can still be ensured to be transmitted in order.

[0056] Embodiment two

[0057] Figure 2 A flowchart of a data transmission method provided for the second embodiment of the application, the relationship between the present embodiment and the above-mentioned embodiments is that a plurality of communication endpoints are configured through abstract classes, as shown in the following figure: Figure 2 The method comprises the following steps:

[0058] S201, configuring a first input endpoint, a second input endpoint, a first output endpoint and a second output endpoint through an abstract class; wherein the first output endpoint is used for the host to send first configuration information to the slave; the second output endpoint is used for the host to send transmission data to the slave; the first input endpoint is used for the slave to send second configuration information to the host; and the second input endpoint is used for the slave to send transmission data to the host.

[0059] The abstract class cannot be directly instantiated, but can be inherited by other classes and the abstract methods thereof are implemented; the output endpoint, namely the bluk on endpoint, is used for the USB host to send data information to the USB slave; the input endpoint, namely the bluk in endpoint, is used for the USB slave to send data information to the USB host; wherein the first output endpoint is used for the USB host to send configuration information (namely first configuration information) to the USB slave, for example, when the data flow direction is from the USB host to the USB slave, the USB host sends the bandwidth parameters of the dedicated bandwidth and the shared bandwidth to the USB slave in advance; the second output endpoint is used for the USB host to send transmission data to the USB slave, namely to send the first service flow and the second service flow in the above technical solution.

[0060] The first input endpoint is used for the USB slave to send configuration information (namely second configuration information) to the USB host, for example, when the data flow direction is from the USB slave to the USB host, the USB slave sends the bandwidth parameters of the dedicated bandwidth and the shared bandwidth to the USB host in advance; the second input endpoint is used for the USB slave to send transmission data to the USB host, namely to send the first service flow and the second service flow.

[0061] Optionally, in the embodiment of the application, after the first input endpoint, the second input endpoint, the first output endpoint and the second output endpoint are configured by the abstract class, the method further comprises: configuring the dedicated bandwidth and the shared bandwidth according to the user configuration information, and sending the configuration result as the first configuration information to the slave, or configuring the dedicated bandwidth and the shared bandwidth according to the second configuration information sent by the slave; wherein the first configuration information and the second configuration information comprise the identification and the required bandwidth of each first type device, and the identification of each second type device.

[0062] Specifically, no matter whether the data flow direction is from the USB host to the USB slave or from the USB slave to the USB host, the configuration of the dedicated bandwidth and the shared bandwidth can be completed by the service personnel, and the USB host completes the configuration of the dedicated bandwidth and the shared bandwidth after obtaining the user configuration information; the first configuration information specifically comprises the identification and the required bandwidth of each first type device, and the identification of each second type device, or the distribution position of the dedicated bandwidth of the first type device, and is further sent to the USB slave to inform the USB slave of the specific bandwidth allocation result.

[0063] Meanwhile, since the USB slave is in communication connection with each external device, the USB slave can also send second configuration information according to the specific types of each external device connected, the second configuration information specifically including the identification and required bandwidth of each first-type device, and the identification of each second-type device, or the distribution position of the dedicated bandwidth of the first-type device, and then sending the same to the USB host to inform the USB host of the specific bandwidth allocation result, so that the configuration information transmission in different directions can be realized through the first input endpoint and the first output endpoint, and the bidirectional transmission of the bandwidth parameters of the dedicated bandwidth and the shared bandwidth is ensured.

[0064] Optionally, in the embodiment of the application, after the first input endpoint, the second input endpoint, the first output endpoint and the second output endpoint are configured through the abstract class, the method further comprises: if it is determined according to the historical transmission record that the digit occupancy rate of the first dedicated bandwidth is less than a preset occupancy threshold, performing bandwidth downsizing processing on the first dedicated bandwidth; if it is determined according to the historical transmission record that the data delay frequency of the second dedicated bandwidth is greater than a preset frequency threshold, performing bandwidth upsizing processing on the second dedicated bandwidth; and sending a bandwidth update result to the slave through the second configuration information, wherein the bandwidth update result comprises a bandwidth downsizing result and / or a bandwidth upsizing result.

[0065] Specifically, the dedicated bandwidth allocated by the USB host for each first-type device can have calculation errors, or each first-type device can change the service type due to service adjustment, so that the corresponding dedicated bandwidth can also change, and the required bandwidth can increase or decrease. Therefore, if it is determined according to the historical transmission record that the digit occupancy rate of the first dedicated bandwidth is less than a preset occupancy threshold, it indicates that the first dedicated bandwidth is too large, and there are unused data digits, and accordingly, the first dedicated bandwidth is subjected to bandwidth downsizing processing.

[0066] If it is determined according to the historical transmission record that the data delay frequency of the second dedicated bandwidth is greater than a preset frequency threshold, it indicates that the second dedicated bandwidth is too small, and often cannot meet the data transmission demand, and there is a data transmission delay problem, and accordingly, the second dedicated bandwidth is subjected to upsizing processing. Accordingly, the dedicated bandwidth is updated based on the historical transmission record, which not only avoids the phenomenon of transmission resource waste caused by the dedicated bandwidth being too large, but also ensures that the dedicated bandwidth meets the real-time demand of data transmission and prevents the occurrence of data transmission delay.

[0067] S202, sending a bandwidth configuration result to the slave through the first output endpoint.

[0068] S203, in response to obtaining the to-be-transmitted data, configuring a first service flow in the to-be-transmitted data, whose receiving object is a first-type device, in a corresponding dedicated bandwidth; wherein the dedicated bandwidth and the first-type device are matched one by one.

[0069] S204, configuring the second service flow with a receiving object being a second type device in the to-be-transmitted data in the shared bandwidth; wherein the priority of the first type device is higher than that of the second type device.

[0070] S205, sending the to-be-transmitted data to the slave based on the second output endpoint through the dedicated bandwidth and the shared bandwidth, so as to send the first service flow to the corresponding first type device and the second service flow to the corresponding second type device through the slave.

[0071] The technical scheme of the embodiment of the present application, after the USB host configures the first input endpoint, the second input endpoint, the first output endpoint and the second output endpoint through the abstract class, completes the bandwidth information configuration through the first input endpoint or the first output endpoint, not only ensures the bidirectional transmission of the bandwidth parameters of the dedicated bandwidth and the shared bandwidth, but also avoids the phenomenon of waste of transmission resources caused by the overlarge dedicated bandwidth, and ensures that the dedicated bandwidth meets the real-time requirement of data transmission and prevents the phenomenon of data transmission delay.

[0072] Embodiment three

[0073] Figure 3 A flow chart of a data transmission method provided by the third embodiment of the present application, the embodiment can be configured in a USB slave (namely, a Device end), and is used for receiving different type service flows according to the dedicated bandwidth and the shared bandwidth, as shown in the following figure: Figure 3 The method comprises the following steps:

[0074] S301, acquiring the first service flow through the dedicated bandwidth, and sending the first service flow to the corresponding first type device.

[0075] S302, acquiring the second service flow through the shared bandwidth, and sending the second service flow to the corresponding second type device.

[0076] As described in the above technical scheme, the USB slave determines the corresponding relationship between the first service flow and the first type device through the distribution position of the first service flow in the dedicated bandwidth or the device identifier in the first service flow, and then sends the first service flow to the corresponding external device; at the same time, the USB slave determines the corresponding relationship between the second service flow and the second type device through the device identifier in the second service flow in the shared bandwidth, and then sends the second service flow to the corresponding external device, thereby completing the data transmission between the USB host and the USB slave.

[0077] The technical scheme of the embodiment of the present application is that the USB slave obtains the first service flow through the special bandwidth, and sends the first service flow to the corresponding first type device, and obtains the second service flow through the shared bandwidth, and sends the second service flow to the corresponding second type device. Therefore, not only the real-time data transmission between the host and the plurality of external devices is realized, but also the defect of controlling different external devices by defining various data packets through the software protocol is avoided, the communication difficulty between the host and the slave is reduced, the resource consumption amount in the data transmission process is reduced, and in addition, when the service flow bandwidth exceeds, the data of the specified type device can still be ensured to be transmitted in order.
