In this implementation, preferably, the intelligent display screen is an intelligent display panel, an intelligent electronic blackboard, an intelligent touch control all-in-one machine, an intelligent interactive large screen or an intelligent electronic blackboard all-in-one machine.
The first wireless communication module and the second wireless communication module may both adopt existing wireless communication modules, for example, including a wireless transceiver chip, one or more antennas suitable for respective frequency bands, a driving circuit, and a data interface. Referring to fig. 1 and 2, each of the first and second wireless communication modules includes two RF antennas RF0 and RF1 to facilitate forming respective wireless access points ap (access point). Specifically, the first wireless communication module is interconnected with the wireless access point of the router illustrated in the upper right corner. In other embodiments, the first wireless communication module may also be communicatively coupled with a 3G or 4G wireless base station.
The external screen projection device can be a screen projector or an electronic device capable of directly projecting a screen. The terminal device generally refers to a terminal device that does not currently have screen projection application. In order to distinguish screen projection data from general internet data conveniently, a screen projection application program can be pre-installed on corresponding equipment, and the screen projection application program can add corresponding distinguishing labels to the two types of data.
The screen transmission data processing module can be used for processing received screen transmission data such as forwarding, encryption or decoding. For example, if the screen transmission device itself has a display screen suitable for screen transmission display, the video data in the screen transmission data can be decoded and played.
The communication control module is at least electrically connected with the second communication module so as to conveniently control the work of the second communication module, and in order to realize control, the communication control module is also used for monitoring the data transmission quantity of the second communication module and judging the monitoring condition. The monitoring of the network data transmission amount may adopt the existing technology, and the upper limit of the network data transmission amount may be determined according to the performance of the second communication module itself and the specific parameters of the second frequency band.

Furthermore, when the second wireless communication module is connected with the external screen projection device and the terminal device at the same time, the screen projection of the external screen projection device and the internet data volume of the terminal device reach or are close to the preset upper limit, the terminal device connected with the second wireless communication module is limited in a targeted manner, the screen transmission data transmission of the external screen projection device is guaranteed preferentially and absolutely, and then the effects that the screen transmission is smooth and is not blocked and the network application of the intelligent display screen is not influenced are achieved under the dual-frequency mode that the external hot spot is connected and the hot spot of the terminal device is opened.
Preferably, the predetermined rules include: and limiting the connection condition of the connected terminal equipment according to the bandwidth of the second wireless communication module and the bandwidth occupied by the connected external screen projection equipment.
In this embodiment, the terminal device is controlled by controlling the proportional relationship between the bandwidth occupied by the external screen projecting device and the total bandwidth, for example, when the bandwidth occupied by the external screen projecting device is 70%, it indicates that the probability of bandwidth occupation is significantly increased, and therefore, the connection condition of the terminal device needs to be limited to fully ensure the screen transmission application.
Preferably, the smart display allows the screen projection contents of a maximum of N external screen projection devices to be displayed simultaneously, and the predetermined rule includes: when the number of the connected external screen projection devices reaches N, or when the total flow of the connected external screen projection devices reaches or approaches the maximum allowable flow of the second wireless communication module, limiting the connection condition of the connected terminal devices.
In this embodiment, it can be understood that, under the condition that the performance of the second wireless communication module and the second frequency band are both determined, the number of external screen projection devices that the smart display screen allows to be simultaneously accessed is also determined. For example, if the bandwidth of the second wireless communication module is 200Mbps, maximum access to 4 external screen transmission devices requiring 50Mbps can ensure that each screen transmission application is not blocked, and therefore, it is relatively reasonable to limit the connection condition of the terminal device by using the number of the accessed external screen projection devices as a standard. Furthermore, since the resolution requirements of the external pass screen devices are different, the required bandwidth may also be different. Under the condition that the requirement on screen transmission definition is low, the number of accessed external screen transmission devices can be increased properly. The total flow of the connected external screen projection equipment reaches or approaches the maximum allowable flow of the second wireless communication module, so that the access amount of the maximum external screen transmission equipment can be ensured, but the connection condition of the connected terminal equipment needs to be limited to realize the connection condition. Preferably, the limiting of the connectivity of the connected terminal device comprises disconnecting or slowing down the connectivity of at least part of the terminal device with the second wireless communication module.
Preferably, the intelligent display screen further comprises a dual-frequency communication circuit board, the first wireless communication module, the second wireless communication module and the screen transmission data processing module are all arranged on the dual-frequency communication circuit board, and the dual-frequency communication circuit board further comprises a connector module, and the connector module is connected with a mainboard of the intelligent display screen through a network interface.
In this embodiment, the first wireless communication module, the second wireless communication module, the screen transmission data processing module and the connector module are all arranged on the dual-frequency communication circuit board, so that the existing mainboard of the intelligent display screen can be conveniently upgraded, and the after-sale services of the first wireless communication module, the second wireless communication module, the screen transmission data processing module and other modules are also facilitated.
Preferably, the connector module comprises a first network interface and a second network interface respectively connected with the mainboard for connecting different operating systems or devices.
In this embodiment, since many current smart display screens have more than two operating systems, for example, an operating system is loaded on a motherboard, and then a computer loaded with another operating system is connected in an extensible manner in a pluggable manner, for example, ops. Preferably, because the android operating system and the Windows operating system are most widely used, the corresponding screen transmission software is more, and a wider market can be covered by carrying the android operating system and the Windows operating system. The first network interface is a PCIe interface and is connected with an android operating system, and the second network interface is a USB interface and is connected with a Windows operating system.
Preferably, the connector module further comprises a power-taking interface, and the power-taking interface is connected with a mainboard of the intelligent display screen to take power from the mainboard. Get the electricity through the mainboard from intelligent display screen, can avoid increasing power source interface in intelligent display screen's outside owing to for the dual-frenquency communication circuit board power supply to intelligent display screen's integration degree has been promoted, and user's use has been made things convenient for from this.
Preferably, the communication control module is at least partially located on a main board of the smart display screen. So, can make full use of the control calculation function of other modules of intelligent display screen, promote the degree of fusion of inside module, and then reduced the hardware cost.
Preferably, the internal routing device further comprises a wired lan port for connecting to the internet by wire. The wired communication module may be configured to establish a data connection with the ethernet through the wired wan port when the first wireless communication module is disconnected from the wireless ethernet, and the wired communication module may also adopt an existing structure, for example, including a general RJ45 interface, and may be connected to the network electronic device through a network cable or the like. Therefore, even if the wireless connection of the first wireless communication module is disconnected, the screen transmission device and the Ethernet communication cannot be influenced, similarly, if the wired network is disconnected, the first wireless communication module is connected with the network, a complementary structure is formed, and the network connection of the intelligent display screen can be ensured when one of the first communication module and the first wireless communication module is provided with the network connection access point.
Preferably, the intelligent display screen is provided with a first operating system, and the communication control module is controlled by at least the first operating system. Because many intelligent display screens possess more than two kinds of operating system at present, carry on first operating system on the mainboard for example, and the computer of carrying on second operating system is connected in the extension of mode extension of rethread can be pegged graft, for example OPS.
Preferably, the second frequency band has frequencies higher than the first frequency band. It can be understood that the higher the radio frequency of the radio transmission is, the larger the data volume that can be transmitted per unit time is, and therefore, it can be guaranteed that the screen transmission is not blocked when the screen transmission is performed by receiving the screen transmission data through the high-frequency second radio communication module. For example, if the bandwidth of the second wireless communication module is 200Mbps or more, even if 4 transmission terminals requiring 50Mbps are accessed, the second wireless communication module will not cause jamming. As shown in fig. 1, the second wireless communication module is connected to a plurality of screen projectors for transmitting screen data of the PC personal computer, such as a PC screen. Preferably, the first frequency band adopts a 2.4G frequency band, and the second frequency band adopts a 5G frequency band. 2.4GHz, and 5GHz refer to frequencies commonly used near these regions, not necessarily the literally exact frequency of 2.4 or 5.0. For example, the frequency band 2.4G may refer to 2400 + 2483GHz, and the frequency band 5G may refer to 5150 + 5824 GHz. Compared with the 5G frequency band of 2.4G, the transmission rate and the bandwidth are obviously improved, so that the screen transmission application can be ensured, and even the application that multiple devices transmit the screen simultaneously can be supported.
The invention also provides a control method of the intelligent display screen, which refers to a flow structure schematic diagram of a first embodiment of the control method of the intelligent display screen in the invention, and the method comprises the following steps:
s100: establishing connection with an external hot spot by using a first frequency band, and starting a self hot spot by using a second frequency band;
in order to use more general network components, the wireless connection of this step can be network transmission according to a predetermined protocol, such as wifi wireless transmission protocol, or 5G transmission protocol. By using different frequency bands, the phenomenon that screen transmission data crowds the bandwidth of the first frequency band or other network application data crowds the first frequency band can be avoided.
S120: when screen transmission data are received by the hot spot, detecting whether the data transmission quantity of the hot spot reaches or approaches to a preset upper limit;
the received screen transmission data can comprise forwarding, encryption or decoding and the like. When screen transmission data is received by the hot spot of the user, the data transmission quantity of the hot spot of the user needs to be detected in order to ensure that screen transmission application needs to detect, so that whether other network applications connected with the same hot spot need to be limited or not is determined.
S140: and when the data transmission quantity of the self hotspot reaches or approaches to a preset upper limit and the self hotspot is connected with the terminal equipment except the screen transmission application, limiting the communication condition of the terminal equipment according to a preset rule.
In this step, since the size of the data stream of the ordinary internet data of the terminal device is also fluctuating, if the data transmission amount of the hotspot of the terminal device reaches or approaches the preset upper limit, the connection condition of the terminal device which is not connected with the hotspot of the terminal device is not limited, and the condition that the ordinary internet data occupies the transmission screen data transmission by crowding easily occurs. Therefore, in order to ensure the transmission of the screen transmission data, when the data transmission quantity of the hot spot of the terminal device is at a preset high level, the communication condition of the terminal device is displayed.
Preferably, in step S140, the predetermined rule includes: and limiting the connection condition of the connected terminal equipment according to the bandwidth of the hot spot and the bandwidth occupied by the connected external screen projection equipment.
In this embodiment, the bandwidth used by the device accessing the hotspot can be used as a relatively accurate standard and can adopt the existing technology. In the step, the terminal device is controlled by controlling the proportional relation between the bandwidth occupied by the external screen projection device and the total bandwidth, for example, when the bandwidth occupied by the external screen projection device is 70%, the probability of bandwidth occupation is obviously improved, so that the connection condition of the terminal device needs to be limited to fully ensure screen transmission application.
Preferably, in step S140, the predetermined rule includes:
whether the number of the connected external screen projection equipment reaches N or not; or
Whether the total flow of the connected external screen projection equipment reaches or approaches the maximum allowable flow of the hot spot of the external screen projection equipment; wherein the content of the first and second substances,
and N is the maximum number of external screen projection devices which are allowed by the intelligent display screen to simultaneously receive and display screen projection data of the intelligent display screen.
It will be appreciated that, in general, the network communication capabilities of the devices are determined, for example, the number of external screen projection devices that are allowed to be simultaneously accessed after a smart display screen is produced is also determined. For example, if the network bandwidth of the second frequency band is 200Mbps, a maximum of 4 external screen transmission devices with 50Mbps are required to be accessed to ensure that each screen transmission application is not blocked, and therefore, the connection condition of the terminal device is relatively reasonable when the number of the accessed external screen projection devices is used as a standard to limit the connection condition of the terminal device. Furthermore, since the resolution requirements of the external pass screen devices are different, the required bandwidth may also be different. Under the condition that the requirement on screen transmission definition is low, the number of accessed external screen transmission devices can be increased properly. The total flow of the connected external screen projection equipment reaches or approaches the maximum allowable flow of the second wireless communication module, so that the access amount of the maximum external screen transmission equipment can be ensured, but the connection condition of the connected terminal equipment needs to be limited to realize the connection condition.
Preferably, step S140 includes the sub-steps of:
s141: determining the number and/or total flow of external screen projection equipment which is currently received and displays screen projection data of the external screen projection equipment;
in this step, the number of the external screen projection devices can be determined by screening the source of the screen projection data, for example, by adding a tag to the screen projection data, a device code or an MAC address corresponding to the external screen projection device can be added to facilitate identification of different external screen projection devices. The total flow can be monitored by adopting the prior art, the total flow reflects the size of the currently actually transmitted screen projection data, and the occupation degree of the total flow on the transmission capability of the hot spot of the user is estimated from another layer.
S142: judging whether the number and/or the total flow reach a preset range;
the screen transmission application can be ensured to be smooth by setting the reasonable number or the total flow range in the step.
S143: and if so, limiting the communication condition of the connected terminal equipment when the hot spot of the terminal equipment is connected with the terminal equipment except the screen transmission application.
In this step, if there is a limit to the screen transmission guaranteeing application according to the detected or collected information display, the connection condition of the connected terminal device is limited.
Preferably, in the substep S141:
the preset range of the number is more than or equal to N-1, wherein N is the maximum number of external screen projection devices which are allowed by the intelligent display screen to simultaneously receive and display screen projection data of the intelligent display screen. Therefore, the second bandwidth can be guaranteed to have sufficient bandwidth surplus, and the external screen projection equipment with the designed number can be normally connected and smoothly transmit the transmission screen data.
Preferably, in the substep S142:
the preset range of the total flow is greater than or equal to a preset percentage of the maximum allowable flow of the hot spot itself.
In this embodiment, according to the percentage of the bandwidth actually occupied by the total flow, when a small number of external screen projection devices are connected, the terminal device can better utilize the vacant bandwidth, so that the bandwidth of the second frequency band is fully utilized.
Preferably, in step S140, the limitation on the connectivity of the connected terminal devices includes disconnecting or slowing down the connectivity of at least some terminal devices with their hot spots.
In this embodiment, disconnecting or slowing down the connection between at least part of the terminal device and the hotspot itself can reduce the occupation of network bandwidth by the terminal device and other devices. If not necessary, only disconnecting or slowing down the connection between part of the terminal devices and the hot spots of the terminal devices can enable the rest devices to normally use the bandwidth of the second frequency band.
