The application proposes a display device comprising: a display, a controller, and a communicator. Wherein the display is used for presenting a picture. The communicator is used for transmission of control signals or data signals in the display device. The display and the communicator are both connected with the controller, and the controller controls the display to display pictures according to signals transmitted by the communicator.

In the embodiment of the present application, the communicator generally accesses a plurality of channels to transmit signals through the plurality of channels. Fig. 5 shows a flow chart of a communication method for a display device, which is performed by a communicator in the display device according to some embodiments of the present application. To perform channel allocation to avoid collisions, the communicator monitors the real-time transmission rate and congestion index of each channel as shown in fig. 5.

Wherein, the real-time transmission rate refers to the current transmission signal rate of the corresponding channel; the congestion index refers to a parameter for reflecting the current congestion degree of a channel. In general, during the transmission of signals, the real-time transmission rate of the channel changes dynamically, and the congestion level, i.e., the congestion index, also changes dynamically.

It is understood that the channel is analogous to a road, the signal transmitted by a first communication module (e.g., USB module) is analogous to a first fleet of vehicles, the signal transmitted by a second communication module (e.g., wireless module) is analogous to a second fleet of vehicles, and when the first fleet of vehicles and the second fleet of vehicles travel on the same road: under the condition that other various conditions are kept unchanged, the higher the running speed of the vehicles on the road is, the more easily the first fleet collides with the second fleet; in the case where various other conditions are maintained, the more crowded the road is, the more likely the first fleet collides with the second fleet.

Therefore, the degree of collision of signals transmitted by different communication modules in the same channel is related to the real-time transmission rate and the congestion index of the channel. That is, the collision index of a channel is related to its real-time transmission rate and its congestion index. More specifically, the collision index of the channel is positively correlated with the real-time transmission rate thereof, and under the condition that other various conditions are kept unchanged, the higher the real-time transmission rate is, the more easily the collision occurs, and the higher the collision index is; and the congestion index is also in positive correlation with the congestion index, and under the condition that other various conditions are kept unchanged, the higher the congestion index is, the more easily the collision occurs, and the higher the collision index is.

In some embodiments, for each channel, the communicator determines a congestion index for the channel based on an average amount of signals transmitted by the channel simultaneously over a preset time period. Specifically, one channel is a frequency band interval, so that one channel can simultaneously transmit a plurality of signals with different operating frequencies. For a particular channel, the communicator monitors the number of signals transmitted simultaneously by that channel to determine the average amount of signals transmitted simultaneously by that channel over a preset period of time. The communicator may then determine the average amount as a congestion index of the channel, or may determine a ratio of the average amount to a preset reference amount as the congestion index of the channel. It should be noted that, no matter what kind of determination method of the congestion index is adopted according to the actual application requirements, the determination method of the congestion index of each channel is kept consistent in the same embodiments.

In the embodiments of the present application, the collision index describes the degree of collision of signals transmitted in the corresponding channel. Therefore, when the communicator in the display device allocates channels for the signals on the basis of the collision indexes and transmits the signals, the channels with collision indexes high in probability can be avoided in real time. Even if different communication modules transmit data on the same channel, the collision index of the same channel is low enough, so that the two modules do not collide. Thereby avoiding the mutual interference of different communication modules when transmitting signals.

Therefore, in the embodiment of the application, in the process of accessing the channel to perform communication, the communicator in the display device monitors the real-time transmission rate and the congestion index of each channel, and further monitors the collision index for reflecting the collision degree of data in the channel on the basis of the monitoring, and further allocates the channel for the signal and transmits the signal based on the collision index. Because the channel allocation and the transmission of the signals are realized according to the collision degree, the low-collision channels can be allocated for the signals for transmission, thereby avoiding the mutual interference of different communication modules when the signals are transmitted.

In some embodiments, the communicator includes: wireless module, USB module. The wireless module performs signal transmission according to a wireless protocol, so that the display device supports wireless communication. The USB module performs signal transmission according to a bus protocol so that the display device supports high-speed bus communication.

In some embodiments, the wireless module comprises a bluetooth module. Through setting up bluetooth module for display device supports near field communication.

In some embodiments, the wireless module comprises a WIFI module. By arranging the WIFI module, the display device supports high-speed wireless communication.

In some embodiments, the WIFI module employs a WIFI6 (sixth generation wireless networking technology) module: the antenna can support 802.11ax protocol, the antenna can support 8 × 8, the working frequency band is 2.4GHz and 5GHz, the antenna can support uplink and downlink bidirectional MU-MIMO (Multi-User Multiple-Input Multiple-Output) and Orthogonal Frequency Division Multiple Access (OFDMA). Through the configuration of the WIFI6 module, the communicator can transmit signals at a higher rate, so that the display device can support higher-speed wireless communication.

In some embodiments, the USB module employs a USB3.0 (third generation universal serial bus) module: 4 data lines are divided into 2 groups, each group is responsible for one transmission direction, the reference frequency of each data line is 2.5GHz, and the transmission of 4K television picture quality can be supported. Through the configuration of the USB3.0 module, the display device can present high-quality 4K television picture quality.

In some embodiments, the wireless module in the communicator comprises a WIFI6 module and the USB module comprises a USB3.0 module. Thus, the display device can support a higher-speed wireless communication service and can present high-quality 4K television image quality.

When the WIFI6 module and the USB3.0 module operate simultaneously, since the operating frequency band 2.5GHz of the USB3.0 module is very close to the operating frequency band 2.4GHz of the WIFI6 module, data transmission of the USB3.0 module may interfere with data transmission of the WIFI6 module without additional control, so that a picture displayed by the display device through wireless transmission is jammed or displayed on a screen. Under the condition, the communicator allocates and transmits the channels for the signals based on the conflict indexes of the channels, so that the interference of the signals transmitted by the USB3.0 module on the signals transmitted by the WIFI6 module is avoided, and the compatibility of the USB3.0 module and the WIFI6 module is realized.

It should be noted that the embodiment of the present application is not limited to solving the interference of the USB3.0 to the WIFI6, and it can be understood that the interference caused by the proximity of the operating frequency bands of the USB module and the wireless module can be solved by the embodiment of the present application.

In some embodiments, the USB module is disposed between the controller and the wireless module, and the wireless module is connected to the controller. Namely, the wireless module is connected with the controller through the USB module. External signals reach the controller after being transmitted by the wireless module and the USB module in sequence, and similarly, the controller signals reach the outside after being transmitted by the USB module and the wireless module in sequence. The USB module is arranged between the controller and the wireless module, so that the signal transmission rate between the controller and the wireless module is improved.

Signals of different transaction types are isolated, so that the signals of different transaction types are effectively prevented from colliding. When the communicator includes both the wireless module and the USB module, the signals of different transaction types mainly refer to: the signal transmitted by the USB module and the signal transmitted by the wireless module.

Wherein V1 is a non-negative number of 0 or more; c is a non-negative number of 0 or more. The congestion index C may be measured by the number of signals transmitted in the channel: the greater the number of signals transmitted in the channel, the greater the congestion index C.

It should be noted that this embodiment only shows an exemplary method for determining the collision index, and it is understood that any method for determining the collision index that positively correlates the real-time transmission rate and positively correlates the congestion index is possible according to the specific application requirements.

In some embodiments, the communicator is configured to:

the signal is transmitted over the low collision channel.

In this embodiment, the communicator assigns signals to low collision channel transmissions for communication.

Specifically, the communicator sets a collision reference value for measuring the height of the collision index in advance. If the conflict index is higher than the conflict reference value, the conflict degree between the signal transmitted by the wireless module and the signal transmitted by the USB module in the corresponding channel is high, and the signal is a high conflict channel; if the conflict index is lower than the conflict reference value, the conflict degree between the signal transmitted by the wireless module and the signal transmitted by the USB module in the corresponding channel is low, and the channel is a low conflict channel.

And after monitoring the conflict indexes of the channels, the communicator screens out the low-conflict channels according to the comparison with the conflict reference value. And distributing signals to the low collision channels, and transmitting the signals by the low collision channels.

The embodiment has the advantage that the signal is transmitted through the low-collision channel, so that the interference of the USB module to the wireless module is avoided, and the speed of channel allocation is ensured.

In some embodiments, the communicator is configured to:

screening out a high-speed channel with the real-time transmission rate being greater than or equal to the target transmission rate from the channels;

In this embodiment, the communicator first meets the requirement of the signal for the transmission rate and then controls the channel switching based on the collision index.

Specifically, in order to meet the communication requirement of the display device in practical application, the signal generally has a certain requirement on the transmission rate. For example: if the display device is to play a video with 2K image quality, the transmission rate of the signal needs to be matched with the 2K image quality; if the display device is to improve the quality of the video to 4K, the transmission rate of the signal needs to be increased to match the 4K quality.

The communicator can access a plurality of channels, and the real-time transmission rate of the channels is recorded as V1; if the V1 of a channel is greater than or equal to the V2 of a target signal, which indicates that the real-time transmission rate of the channel can meet the requirement of the target signal for the transmission rate, the channel is regarded as a high-speed channel relative to the target signal.

For a single target signal: recording the target transmission rate as V2; screening out high-speed channels with V1 being more than or equal to V2, wherein only one high-speed channel can be screened out, and a plurality of high-speed channels are screened out generally; screening one high-speed channel from a plurality of high-speed channels as a target high-speed channel, and transmitting the target signal; and then controlling the channel switching of the target signal based on the conflict index of the target high-speed channel in the process of transmitting the target signal: if the conflict index is lower than the preset conflict reference value, the target signal is transmitted through the target high-speed channel without interference, so that channel switching is not needed; if the collision index is higher than or equal to the preset collision reference value, it indicates that the target signal is transmitted through the target high-speed channel and interference occurs, so that channel switching is required, and the target signal is continuously transmitted through other channels.

The embodiment has the advantages that the requirement of the signal on the transmission rate is met in advance, and then the channel switching is controlled based on the conflict index, so that the interference of the USB module on the wireless module is avoided, and meanwhile, the display equipment is ensured to be capable of providing high-quality video service as far as possible.

In some embodiments, the communicator is configured to:

the target signal is transmitted through the target high speed channel.

In this embodiment, the communicator screens out the target high speed channel from the high speed channels based on the congestion index.

Specifically, for a single target signal: the communicator screens out a plurality of high-speed channels corresponding to the target signal, and then sets the highest congestion index among the high-speed channels as a target high-speed channel to transmit the target signal through the target high-speed channel.

It should be noted that this embodiment is merely an example showing an alternative implementation. It will be appreciated that the target high speed channel may be screened out in other ways according to the actual application requirements, for example: and randomly screening a target high-speed channel from the high-speed channels.

In some embodiments, the communicator is configured to:

if the conflict index of the target high-speed channel is higher than or equal to a preset conflict reference value in the process of transmitting the target signal, switching from the target high-speed channel to a low-speed channel of which the real-time transmission rate is lower than the target transmission rate, and continuously transmitting the target signal through the low-speed channel.

In this embodiment, the communicator performs channel switching through a down-speed process.

Specifically, in the process of transmitting the target signal through the target high-speed channel, if the collision index of the target high-speed channel is higher than or equal to a preset collision reference value, performing speed reduction processing on the target signal: and screening out a low-speed channel with the real-time transmission rate lower than the target transmission rate, switching the channel for transmitting the target signal from the target high-speed channel to the low-speed channel, and continuously transmitting the target signal through the low-speed channel. Preferably, the collision index of the switched low speed channel is lower than the collision reference value.

The embodiment has the advantages that the channel switching is carried out through the speed reduction processing, and meanwhile, the requirements of the display equipment on the transmission rate and the interference resistance are considered.

In some embodiments, the communicator is configured to:

determining the grade of the target high-speed channel;

and if the conflict index of the target high-speed channel in the process of transmitting the target signal is higher than or equal to a preset conflict reference value, continuously switching to a channel at a lower level from the level of the target high-speed channel and continuously transmitting the target signal through the channel at the lower level until the conflict index of the channel at the lower level is lower than the conflict reference value, and terminating the switching.

In this embodiment, the communicator performs channel switching through a progressive speed reduction process.

Specifically, the communicator performs classification for each channel according to the transmission rate: the higher the real-time transmission rate, the higher the grade; the real-time transmission rates of the channels of the same grade are different within a certain range; the real-time transmission rate of any channel of the high grade is higher than that of any channel of the low grade.

In the process of transmitting the target signal through the target high-speed channel, if the conflict index of the target high-speed channel is higher than or equal to a preset conflict reference value, performing gradual speed reduction processing on the target signal: switching to a channel lower by one level than the level of the target high-speed channel and continuing to transmit the target signal through the lower channel; if the conflict index of the switched channel is still higher than or equal to the conflict reference value, switching to a channel at a lower level; and continuously switching until the collision index of the switched channel is lower than the collision reference value, terminating the switching, and continuously transmitting the target signal through the finally switched channel.

For example: there are 13 channels that the communicator can access, which are sequentially marked as channel 1, channel 2, channel 3, and up to channel 13.

Dividing a channel with a real-time transmission rate higher than or equal to 900Mbps into A grades; dividing a channel with a real-time transmission rate lower than 900Mbps and higher than or equal to 600Mbps into a B level; dividing a channel with a real-time transmission rate lower than 600Mbps and higher than or equal to 300Mbps into a C grade; channels with real-time transmission rates below 300Mbps are classified as D class.

Assuming that according to the dividing method, channels 1-3 are of A grade; channels 4-6 are B grades; channels 7-10 are in C grade; channels 11-13 are of D-class.

The target transmission rate of the target signal is 800 Mbps. And finally screening out a channel 2 with the real-time transmission rate of 1000Mbps from a plurality of high-speed channels with the real-time transmission rate of more than or equal to 800Mbps as a target high-speed channel, and transmitting the target signal through the channel 2.

If the collision index of the channel 2 is higher than or equal to the collision reference value in the process of transmitting the target signal by the channel 2, starting from the A grade, firstly switching to the B grade (switching to one of the channels 4-6), and continuously transmitting the target signal through the switched B grade channel; and if the collision index of the switched B-level channel is still higher than or equal to the collision reference value, switching to the C level (switching to one of the channels 7-10), and continuing to transmit the target signal through the switched C-level channel. Similarly, the subsequent processes are not described again. The handover is terminated until the collision index of the channel to which the handover is made is lower than the collision reference value, or until the downgrade cannot be continued any more.

The embodiment has the advantage that the channel switching is carried out through the gradual speed reduction processing, so that the requirement of the display equipment on the transmission rate is ensured more finely while the requirement of the display equipment on interference resistance is ensured.

FIG. 9 illustrates a flow diagram for a gradual slow down according to some embodiments of the present application.

As shown in fig. 9, in this embodiment, a channel is searched for a target signal to be transmitted. After finding the channel, it is confirmed whether it is suitable (i.e., whether the collision index of the channel is lower than the collision reference value): if the channel is suitable, the channel is searched for and transmitted; if not, the speed is reduced, the channel is switched, whether the channel is suitable or not is confirmed, and the circulation is continued until the suitable channel is found.

It should be noted that this embodiment only exemplarily shows a flow diagram of the gradual speed reduction, and should not limit the function and the application scope of the present application.

In some embodiments, the communicator is configured to:

screening high conflict channels with the conflict indexes higher than or equal to a preset conflict reference value from the channels;

In this embodiment, the communicators communicate by time-sharing processing.

Specifically, the communicator screens out high-collision channels from the channels according to a preset collision reference value. There may be only one, and typically many, high collision channels.

For multiple target signals that have been allocated to the same high collision channel: sequentially transmitting target signals according to the arrival sequence of the data; in the process of sequential transmission, the next target signal can be transmitted again only after the previous target signal is transmitted.

This embodiment has the advantage that the communication is performed by time-sharing processing, which reduces the burden on high collision channels.

In some embodiments, the communicator is configured to:

and in the process of transmitting the former target signal through the same high collision channel, carrying out channel switching control on the latter target signal.

In this embodiment, the system performs channel switching control between time slots of sequential transmission while performing communication by time division processing.

Specifically, for a plurality of target signals allocated to the same high collision channel, in the process of sequential transmission: and in the process of transmitting the previous target signal, carrying out channel switching control on the next target signal so as to switch the next target signal to a low-collision channel with a collision index lower than a collision reference value.

The time slot occupied by the process of transmitting each target signal is denoted as T. Generally, the timeslot T is the sum of the channel cleaning duration, the antenna switching duration, the transmission duration, and the physical layer processing duration. In the process of sequential transmission: and if the time slot occupied by the transmission of the previous target signal is T, carrying out channel switching control on the next target signal during the time slot T.

This embodiment has an advantage in that, while communication is performed by time-sharing processing, channel switching control is also performed between time slots of sequential transmission, further reducing the burden of high-collision channels.

the controller is configured to color each channel and control the display to perform visual display according to the color pre-associated with each gradient, and simultaneously, color and perform visual display on the signals transmitted by each channel, wherein the color of the signals is consistent with the color of the channel.

In this embodiment, the controller of the display device performs coloring processing on the channel and the signal, and then controls the display to perform visual display.

Specifically, the communicator performs gradient division for each channel according to the collision index: the higher the conflict index, the higher the gradient; for channels with the same gradient, the collision indexes are different within a certain range; the collision index of any channel with high gradient is higher than that of any channel with low gradient; each gradient is pre-associated with a corresponding color.

The controller colors and displays each channel according to the gradient of each channel, and colors and controls the display to display visually according to the signals transmitted by the channels by the same coloring processing.

For example: the achievable range of the conflict index is 0-100 units. Dividing channels with collision indexes higher than or equal to 75 units into a fourth gradient; dividing channels with collision indexes lower than 75 units and higher than or equal to 50 units into a third gradient; dividing channels with collision indexes lower than 50 units and higher than or equal to 25 units into second gradients; channels with collision indices below 25 units are divided into first gradients.

The fourth gradient is pre-associated with red, the third gradient with orange, the second gradient with yellow and the first gradient with green.

If the collision index of a channel is 65, the controller colors the channel to orange and controls the display to visually display the channel, and also colors the signal transmitted by the channel to orange and visually display the signal.

The embodiment has the advantages that the coloring and the visual display are carried out, the communication state of the display device can be intuitively displayed to the manager, and the reference information related to the communication is intuitively provided for the manager.
