Description

Technical Field

[0001] The present invention relates to the field of electronic digital data processing technology, and in particular to an intelligent interactive commercial display projection and multi-screen display system. Background Art

[0002] With the development of computer technology, more and more types of electronic devices have been developed and widely used. Early commercial advertisements mainly relied on static media such as printed posters and banners. The content of static media cannot adapt to market changes and the diversity of consumer needs, lacks appeal, and has high information update costs.

[0003] For example, the multi-display terminal projection system and method for smart classrooms disclosed in Chinese patent CN114546311B, the existing projection technology cannot solve the problem of simultaneously projecting different contents on multiple display terminals, but cannot interact with multiple devices and users, resulting in poor interactivity and lack of projection or circulation means.

[0004] In addition, traditional commercial display systems mostly use static content, such as traditional billboards and posters. This type of display content lacks dynamic interactivity and cannot automatically adjust according to audience feedback or changes in the external environment, resulting in inefficient information transmission and difficulty in attracting and maintaining customer attention.

[0005] Due to the lack of effective interactive mechanisms, traditional commercial display methods are difficult to stimulate customer participation and limit opportunities for interaction between brands and customers. This is a major flaw in improving customer experience and promoting sales conversion rates. At the same time, updating content requires manual intervention and cannot reflect market changes or specific events in real time.

[0006] The present invention is made to solve the common problems in the field, such as lack of flow interaction, poor interaction comfort, inability to provide interaction, poor synchronization effect of screen projection and multi-screen display, poor environmental adaptability and low intelligence. Summary of the invention

[0020] Furthermore, the circulation state evaluation unit obtains the display state data of the display device collected by the circulation feedback unit, and calculates the circulation state index Circulation according to the following formula:

[0021] Circulation = S·(B optimal -BB optimal |-α·BDiff)·lg(R)·CAdapt β ;

[0042] The following is an explanation of the embodiments of the present invention through specific embodiments. Those skilled in the art can understand the advantages and effects of the present invention from the contents disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. In addition, the drawings of the present invention are only simple schematic illustrations and are not depicted according to actual sizes. It is stated in advance. The following embodiments will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention.

[0043] Embodiment 1: According to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this embodiment provides an intelligent interactive commercial display projection and multi-screen display system, which includes a server and a display device, and further includes a circulation module, an interaction module, a display module, and an environment perception module. The server is connected to the circulation module, the interaction module, the display module, and the environment perception module, respectively, and transmits the intermediate data and process data of the circulation module, the interaction module, the display module, and the environment perception module to the database of the server for storage for query or call;

[0044] The interaction module is used for the display device to interact so as to determine the device identification code of the display device. The environment perception module perceives the environment in which the display device is located so as to obtain the environment data of the display device. The flow module allows the interactive display device to flow the display content and dynamically feeds back the display status data of the display device to the display module. The display module obtains the environment data collected by the environment perception module and dynamically adjusts the display parameters of the display device.

[0045] The commercial display projection and multi-screen display system also includes a central processor, which is respectively connected to the circulation module, the interaction module, the display module, and the environment perception module, and centrally controls the circulation module, the interaction module, the display module, and the environment perception module based on the central processor, and stores the control data in the database of the server to improve the precision control of the entire system over the projection and multi-screen display of the display device;

[0046] In this embodiment, the display device to be transferred needs to be interactively identified and establish a bound communication connection relationship through the interaction module before the display device display content can be transferred;

[0047] Meanwhile, in this embodiment, the display devices referred to are devices with the same resolution;

[0048] Further, the interaction module includes an interaction unit and an interaction management unit, wherein the interaction unit is used for interaction between the display devices to collect device identification codes of the interacting display devices, and the interaction management unit manages the interacting display devices and establishes a communication transmission channel;

[0049] The interactive unit includes a transmission component and a support base, the support base supports the transmission component, and the transmission component is used to perform interactive transmission to the display device to obtain a device identification code of the display device;

[0050] Wherein, after the display device approaches the transmission component, Bluetooth pairing or near field communication is triggered, so that the device identification code of the display device is transmitted to the transmission component;

[0051] Further, the transmission component includes a transmission area, an NFC (Near Field Communication) communicator and a Bluetooth communicator, and when the display device is close to the range of the transmission area, the connection and pairing of the display device with the NFC communicator and the Bluetooth communicator is triggered;

[0052] The process of the interaction management unit managing the display device and establishing a communication transmission channel includes the following steps:

[0053] S1. Device identification and registration

[0054] When the display device interacts (via a touch screen, remote control, or the transmission component as an example), the interaction unit first collects the device identification code of the device (such as a MAC address, device ID, etc.); the interaction management unit uses the collected device identification code to find or register the device in the system; this may include querying the device database to determine whether the device is registered, and if not, adding the device to the system;

[0055] S2. Communication channel establishment

[0056] Once the device is identified and registered, the interaction management unit is responsible for establishing a communication channel with the device, which may be based on different communication protocols such as TCP / IP, Bluetooth, Wi-Fi Direct, etc.

[0057] Choose the communication protocol and technology that best suits the current device and network or transmission channel conditions; for example, for devices within a local area network, TCP / IP protocol may be preferred; while for personal devices, Bluetooth or Wi-Fi Direct may be a better choice;

[0058] S3. Communication channel management

[0059] Managing communication channels includes monitoring channel status, handling communication failures, and optimizing data transmission;

[0060] Status monitoring: Regularly check the status of the communication link to ensure link stability;

[0061] Fault handling: Automatically retry or reestablish the communication channel when a communication interruption or quality degradation is detected; the degradation of communication quality is detected by sending a timestamped probe packet and measuring the round-trip time (RTT):

[0062] RTT=T receive -T send ;

[0063] Where, T receive is the timestamp of acceptance, T send Timestamp for sending;

[0064] It can also be determined by the packet loss rate (PacketLossRate), that is, by comparing the number of packets sent and successfully received:

[0065]

[0066] Where N sent is the number of packets sent, and its value is based on the existing network performance monitoring tools, N lost is the number of packets lost, and its value utilizes existing network performance monitoring tools;

[0067] Data transmission optimization: Dynamically adjust data compression ratio, fragment size and transmission rate parameters according to network or transmission channel conditions and device capabilities to optimize performance;

[0068] Adjusting the data compression rate means dynamically adjusting the data compression rate according to the changes in the bandwidth of the network or transmission channel; increasing the compression rate when the bandwidth is low to reduce the amount of transmitted data; and reducing the compression rate when the bandwidth is sufficient to improve data quality;

[0069] In this embodiment, the compression rate is increased when the bandwidth utilization exceeds a threshold;

[0070] In this embodiment, the size of the data fragment is adjusted according to the delay and packet loss rate of the network or transmission channel; smaller fragments are used in a network or transmission channel with high delay or high packet loss rate to reduce the amount of data retransmitted due to the loss of a single fragment; in a stable network or transmission channel environment, larger fragments are used to reduce management overhead and improve transmission efficiency;

[0071] The segment size (SegmentSize) is based on RTT and packet loss rate, then:

[0072]

[0073] In the formula, RTT is the round trip time, Bandwidth is effective The effective bandwidth after taking into account the packet loss rate is calculated according to the following formula:

[0074]

[0075] Wherein, MSS is the maximum segment size. In this embodiment, the MSS value is usually set to 1460 bytes, RTT is the round-trip time, and PacketLossRate is the historical packet loss rate;

[0076] Dynamic adjustment of the transmission rate parameter is based on the current network or transmission channel bandwidth and device processing capabilities to dynamically adjust the data transmission rate; this helps to avoid network or transmission channel congestion and ensure that the device can process the received data in a timely manner, that is, determined in the following two ways:

[0077] 1) In each RTT period, if no packet loss is detected, increase the rate:

[0078]

[0079] In the formula, rate current is the current data transmission rate, MSS is the maximum segment size, and CWND is the congestion window, whose value is determined according to the following conditions:

[0080] CWND starts from a small value (such as 1 or 2 MSS), and increases by one MSS for each ACK message received when no packet loss is detected. This causes CWND to grow exponentially until a packet loss event is encountered or the slow start threshold (ssthresh) is reached.

[0081] Once CWND reaches the slow start threshold, TCP enters the congestion avoidance phase. In this phase, the growth of CWND turns into linear growth, with one MSS added for each RTT, gradually increasing until the next packet loss event occurs.

[0082] 2) If packet loss is detected, reduce the current rate:

[0083]

[0084] In the formula, rate current is the current data transmission rate, which is directly measured by the network tool;

[0085] S4. Data exchange and synchronization

[0086] Through the established communication channel, the interaction management unit is responsible for sending and receiving instructions and synchronizing data; that is, using data encryption and compression technology to ensure the security and efficiency of data transmission; at the same time, the confirmation and retransmission mechanism at the application protocol level ensures data integrity. Specifically,

[0087] 1) Data packet sending

[0088] Process: When the sender has data to send, it divides the data into packets (if necessary) and assigns a unique sequence number to each packet before sending it onto the network or transmission channel;

[0089] 2) Confirm receipt

[0090] Process: After receiving each data packet, the receiver checks the integrity of the data packet (such as through a checksum or CRC); if the data packet is intact, the receiver will send an acknowledgment message (ACK), which contains the sequence number of the successfully received data packet;

[0091] 3) Waiting for confirmation and timeout processing

[0092] After sending a data packet, the sender starts a timer to wait for an acknowledgment message. If no acknowledgment message (ACK) is received within the timeout period, or the sequence number of the received acknowledgment message (ACK) does not match the sent data packet, the data packet is considered to need to be retransmitted.

[0093] 4) Data retransmission

[0094] Once it is determined that a packet needs to be retransmitted (either because an ACK was not received or an incorrect ACK was received), the sender will resend the packet; usually, there is an upper limit on the number of retransmissions to avoid infinite retransmissions;

[0095] 5) Receiver data assembly

[0096] The receiver reassembles the received data packets into complete data in the correct order according to the sequence numbers of the data packets;

[0097] 6) Flow control and congestion control

[0098] Additional mechanisms: To more effectively manage network or transmission channel resources and prevent network or transmission channel congestion, the sender may dynamically adjust the sending rate and window size based on the receiver's processing capabilities and network or transmission channel conditions;

[0099] In this embodiment, a specific example is provided: assuming that the application protocol defines the maximum size of each data packet as 1024 bytes, and the sender wants to send a 4096-byte message; the sender divides the message into 4 packets and sends them, each packet contains 1024 bytes, and assigns a sequence number (1, 2, 3, 4) to each packet; for each packet sent, the sender sets a timeout timer to wait for ACK; if the corresponding ACK is not received before the timer times out, the sender will retransmit the data packet; the receiver assembles these packets in the order of the sequence numbers and sends ACK for each successfully received packet;

[0100] The reliability of data transmission is greatly improved through confirmation and retransmission mechanisms, especially in network or transmission channel environments prone to errors and packet loss;

[0101] The flow module includes a content scheduling unit, a flow feedback unit, and a flow state evaluation unit. The flow feedback unit collects display state data of the display device. The flow state evaluation unit evaluates the content flowed and displayed by the display device according to the display state data collected by the flow feedback unit to form an evaluation result. The content scheduling unit schedules the flow display device according to the evaluation result so that the display device can display synchronously.

[0102] Wherein, after the display device performs the interactive operation, the trigger will be displayed synchronously on at least two of the display devices;

[0103] Further, the content scheduling unit includes a content processor, a network router, a memory, and a signal processor, wherein the content processor processes display content to be displayed on the display device, the network router provides communication between at least two streaming display devices, the memory temporarily stores content to be processed and forwarded, and the signal processor is used to process all input and output signals;

[0104] Wherein, the input and output signals include encoding and decoding of images, audio and control signals;

[0105] Furthermore, the flow feedback unit includes a monitor and a data recorder, wherein the monitor is used to retrieve display status data of the display device, and the data recorder is used to record the status data collected by the monitor;

[0106] Wherein, the display status data includes on / off status, brightness and resolution;

[0107] The monitor is connected to a control panel of the display device and calls the display status data of the display device;

[0108] Furthermore, the circulation state evaluation unit obtains the display state data of the display device collected by the circulation feedback unit, and calculates the circulation state index Circulation according to the following formula:

[0109] Circulation = S·(B optimal -|BB optimal |-α·BDiff)·1g(R)·CAdapt β ;

[0110] Wherein, S is the on / off state of the current display device. In this embodiment, the display device is set to be on as 1 and off as 0. B is the brightness value of the current display device (expressed in a numerical range, 0 is the lowest brightness and 100 is the highest brightness), and its value is directly measured by the monitor. B optimal is the ideal brightness value, and its value is set by the system. BDiff is the average brightness difference between at least two display devices. The smaller the difference, the more consistent the brightness. CAdapt represents the content adaptability, ranging from 0 to 1, 1 represents complete adaptation, and 0 represents incompatibility. α and β are weight coefficients, and their values ​​are set by the system. R is the total number of pixels in the image, satisfying:

[0111] R = w·h;

[0112] Where w is the number of pixels of width, h is the number of pixels of height;

[0113] Furthermore, the average brightness difference Bdiff between at least two display devices is calculated according to the following formula:

[0114]

[0115] In the formula, B i is the brightness value of the i-th display device, n is the number of display devices, B avg is the average brightness of the display device, and its value is calculated according to the following formula:

[0116]

[0117] In the formula, B i is the brightness value of the i-th display device, and n is the number of display devices;

[0118] Content adaptability CAdapt is calculated according to the following formula:

[0119]

[0120] In the formula, R device is the resolution of the display device, and its value is determined according to the maximum resolution of the display device. content is the original resolution of the displayed content, which is directly determined according to the inherent parameters of the displayed content; for the weight coefficients α and β, the value range is [0, 1]. This embodiment provides examples of values ​​for different scenarios:

[0121] 1) Gallery display system:

[0122] If a high degree of visual consistency and adaptability is required, then:

[0123] α = 0.8;

[0124] β = 0.8;

[0125] 2) Outdoor advertising boards:

[0126] Brightness difference is more critical because the external light varies greatly, so:

[0127] α = 0.9;

[0128] β = 0.5;

[0129] 3) Conference room display screen:

[0130] Content adaptability is critical to ensure that all participants can see the content clearly, then:

[0131] α = 0.4;

[0132] β = 0.9;

[0133] 4) Retail store windows:

[0134] The requirements for brightness and content adaptability are relatively balanced, then:

[0135] α = 0.6;

[0136] β = 0.6;

[0137] In short, the value of the weight coefficient is determined by the actual usage scenario and input from the human-computer interaction interface, which can be understood by those skilled in the art, so it will not be described in detail in this embodiment;

[0138] If the circulation state index Circulation is lower than the monitoring threshold View set by the system, the content scheduling unit is triggered to provide feedback to the display module, and the display module adjusts the display content of the display device;

[0139] If the circulation status index Circulation is higher than the monitoring threshold View set by the system, it means that the display content of the display device meets the system requirements, and the system does not need to make immediate adjustments, and records this status as a reference for optimization;

[0140] The monitoring threshold View set by the system is set by the system or the administrator according to the actual situation. This is a technical means well known to those skilled in the art. Those skilled in the art can learn about this technology by consulting relevant technical manuals. Therefore, in this embodiment, it will not be described one by one.

[0141] In this embodiment, the adjustment of the display device by the content scheduling unit includes synchronizing the displayed content to maintain high efficiency and high quality of content flow;

[0142] The content scheduling unit's adjustment strategy for displaying content includes: adjusting the time deviation ΔT i The content displayed on the display device can be synchronized:

[0143] ΔT i =λ·(T avg -T i );where T avg is the average time that the same content appears on all display devices. Where n is the number of display devices, T i is the appearance time of the content on the i-th display device, λ is the adjustment coefficient, and its value is determined according to the following formula:

[0144]

[0145] In the formula, Circulation is the circulation status index, and View is the monitoring threshold set by the system;

[0146] The content scheduling unit adjusts the time deviation ΔT i Adjustments are made to enable synchronization between the display devices, thereby improving the precise synchronization of the display content between multiple devices;

[0147] Through the cooperation between the interaction module and the flow module, the status of the display device for screen projection or multi-screen display can be monitored, ensuring that the display status of the display device is more reliable, and improving the overall system with high interactive comfort, strong flow interaction ability, good synchronous display effect and high intelligence;

[0150] Further, the display management unit includes a communicator and a video processor, the communicator is used for at least two of the display devices to communicate and transmit, and the video processor is used to process the displayed content and transmit the displayed content to the display device through the communicator;

[0151] Wherein, the connection mode between the communicator and the display device includes wired connection and wireless connection;

[0152] The display evaluation unit obtains the environmental data collected by the environmental perception unit, and calculates the evaluation index EV according to the following formula:
