[0041] In view of at least one of the above problems, embodiments of the present invention aim to provide a centralized control platform system, control method and equipment for controlling large-scale performance equipment, thereby constructing a centralized control platform system for large-scale performance control with higher reliability, simpler hardware integration, higher processing accuracy and higher processing efficiency, realizing a precise and efficient collaborative control centralized control processing architecture, ensuring multi-type and multi-task management process arrangement, high-reliability complex motion control, and multi-visual and multi-sound effect fusion control, fully meeting the centralized control needs of heterogeneous equipment such as lighting, sound, video and mechanical motion in complex scenes of large-scale performance activities.

[0042] like Figures 1-3 As shown, one aspect of the present invention provides a centralized control platform system 100 for controlling large-scale exhibition equipment, which includes a touch display module 101, a main control board module 102 and an output interface board module 103.

[0043] In response to touch operation detection, the touch display module 101 generates at least one analog control signal;

[0044] The input terminal of the main control board module 102 is connected to the interface terminal of the touch display module 101 based on a preset analog signal interface, and generates multiple equipment control signals in response to at least one analog control signal; its output terminal is connected to the bus terminal of the touch display module 101 based on a preset interconnection expansion bus, and is used to output multiple equipment control signals.

[0045] The output interface board module 103 is connected to the main control board module 102 based on a preset interconnection expansion bus, and is used to output multiple equipment control signals to a preset switch for the purpose of realizing large-scale exhibition control.

[0046] The main control board module 102 includes a first digital processing unit 201 and a second digital processing unit 202.

[0047] The first digital processing unit 201 receives at least one digital control signal corresponding to at least one analog control signal input based on a preset analog signal interface, calls the first real-time data temporarily read and written and the preset first control data, and generates multiple equipment control signals.

[0048] The second digital processing unit 202 calls the second real-time data that is temporarily read and written and the preset second control data to generate signal reference information corresponding to at least one digital control signal, and generates signal analysis information of multiple equipment control signals output by the first digital processing unit 201. Based on the comparison result between the signal reference information and the signal analysis information of the corresponding equipment control signal, it outputs multiple equipment control signals.

[0049] In this embodiment of the invention, large-scale performances can include various live-action performances such as concerts, opening and closing ceremonies of various large-scale events, and various large-scale galas. The centralized control platform system can be a centralized operation and control physical platform capable of providing real-time control of large-scale performances, for example, providing control functions such as touch display, backup scene buttons, one-button emergency stop, and remote open interfaces. In this embodiment of the invention, data communication or signal transmission can be further achieved through a preset switch with heterogeneous performance equipment such as lighting equipment, sound equipment, video equipment, and various mechanical motion equipment (such as lifting stages, wire work, etc.). The preset switch can be a network device that forwards or transmits data based on photoelectric signals, i.e., a switch, specifically such as an Ethernet switch.

[0050] The touch display module 101 may include a display device with touch control, such as a touch monitor (e.g., a touch screen), which can generate corresponding touch signals by detecting touch actions. Touch operation detection can be understood as the detection of touch actions by the touch display module 101. For example, when a finger or other object touches a touch screen mounted on the front of the display, the touch screen controller detects changes in capacitance, photoelectricity, etc., at the touched location (in coordinate form) and generates a corresponding operation detection signal. The analog control signal can be an analog signal generated through the aforementioned touch operation detection. It can be received and transmitted via a preset analog signal interface, including analog signals generated from voltage and / or current signals when adjusting equipment parameters in a performance setting, which can be used to adjust the brightness and operating speed of the equipment in real time. Specifically, the analog control signal can be transmitted via a preset analog signal interface on the touch display module 101.

[0051] The analog control signal can be an analog signal that includes performance control information involving multiple heterogeneous performance equipment (such as lighting equipment, bulb models, switching times, and lighting duration). For example, the "One-Click Start" button displayed on the touch screen of the touch display module, once a touch of this button is detected, can generate an analog control signal that simultaneously includes performance control information for multiple performance equipment, such as the control of lighting equipment (e.g., lighting equipment model, serial number, bulb model, switching time, lighting duration, brightness, etc.) and the control of sound equipment (e.g., sound equipment model, serial number, volume, playback time, playback duration, etc.).

[0052] By processing the analog control signal, corresponding control signals for each piece of performance equipment can be generated, i.e., equipment control signals. These equipment control signals can include signals representing various control parameters such as the model, code / number, name, working time, and working duration of each required piece of performance equipment. They can also include call signals that can invoke these control parameters, and can simultaneously include the manufacturer, model, and data / signal protocol of various heterogeneous performance equipment. These equipment control signals can be transmitted externally through a preset interconnect expansion bus. This preset interconnect expansion bus can be a local parallel bus based on external component interconnection standards, such as PCI (Peripheral Component Interconnect) bus and PCIe (Peripheral Component Interconnect Express) bus, etc. The preset interconnect expansion bus is mainly used for signal or data transmission.

[0053] The main control board module 102 can be the main control part of the centralized control platform system 100 of this embodiment of the invention. It can receive input instructions from various modules, process performance control logic (the relevant control logic can be preset and stored in the flash memory of the main control board module 102, such as Flash ROM), and output further control instructions, similar to the logic processing of data and signals by the central processing unit (CPU). Specifically, based on the preset analog signal interface between the main control board module 102 and the touch display module 101, the main control board module 102 can receive at least one analog control signal from the touch display module 101. The main control board module 102 can have multiple preset analog signal interfaces, and can also simultaneously realize data or signal transmission through a preset interconnection expansion bus.

[0054] In one embodiment of the present invention, the touch display module 101 is mainly used to realize human-computer interaction, allowing relevant operators to perform tasks such as inputting performance control commands and viewing system status information. Figure 3 As shown, the touch display module 101 can also be connected to the main control board module 102 via a video conversion card, bus conversion board (such as a PCIe graphics card), etc., to realize the conversion and transmission of analog control signals detected by the touch screen and touch detection control related information. During the control signal input and output process, the touch display module 101 can further input and output related data. Before passing through the video conversion card and bus conversion board, it may include system-wide unified digital display data formats, such as RGB pixel data and interface element coordinate data, which can only be recognized by the aforementioned bus conversion board and cannot directly drive the touch screen. After passing through the video conversion card and bus conversion board, it can obtain display interface signals in formats such as LVDS.

[0055] In some embodiments of the present invention, the bus conversion board can be responsible for processing the display data of the main control board module 102, generating signals adapted to the video conversion card, and driving the touch display module 101 to display the interface. Furthermore, the connection between the bus conversion board and the main control board module 102 can be achieved through a preset interconnect expansion bus interface (such as a PCIe interface), and the output of the bus conversion board can be connected to a video conversion card. The video conversion card can be any type of video conversion card, and specific details are not elaborated upon.

[0056] Specifically, in the touch display module 101, the bus conversion board is responsible for the graphical processing of digital display data. It mainly receives the raw digital display data output by the main control board module 102, performs rendering and resolution adaptation, and generates standardized graphics card output signals (but cannot directly drive the touch screen interface display). Then, it performs interface adaptation of signal format through the video conversion card. Specifically, it converts the standardized graphics card output signals received from the bus conversion board into signal formats compatible with the physical interface of the touch screen (such as LVDS, HDMI, etc.), and optimizes the signal timing and level to ensure that the touch screen can receive stably and realize interface display.

[0057] like Figure 3 As shown, the output interface board module 103 is mainly used to output the equipment control signals generated by the aforementioned main control board module 102 via a preset interconnection expansion bus. Specifically, it sends these data or signals to a preset switch, enabling the preset switch to forward the corresponding equipment control signals to various heterogeneous performance equipment, thereby achieving synchronous and precise control of various heterogeneous performance equipment. The output interface board module 103 can provide an output interface board and a bus conversion board based on the preset interconnection expansion bus, which are used to implement signal output and signal conversion functions, respectively.

[0058] Both the bus conversion board and the output interface board can be implemented based on the high-speed serial computer extended bus standard to transmit various data or signals based on display data. For example, the transmitted display data can be visual information such as the operation interface of the centralized control system, equipment status, and control parameters, with the aim of driving the touch screen to present an intuitive human-machine interface. The operation interface layout data can include the positions of interface elements, button icons, and text descriptions in areas such as the equipment control area, status monitoring area, and lever control area of ​​the central control console; equipment status display data can include online / offline indicators, brightness values, and temperatures of lighting equipment; the running / stopped status and current position of mechanical equipment; and the volume decibels and sound effect modes of audio equipment; control operation feedback data can include a dynamic "Switching in progress" prompt displayed on the interface after the operator presses the "Scene Switch" button, and a real-time synchronous display of brightness and volume value change curves after lever adjustment.

[0059] For the output interface board module 103, the output interface board can be implemented using a preset interconnect expansion bus conversion board, such as a PCIe conversion board. It primarily converts the bus signal format (e.g., the aforementioned equipment control signal) of the main control board module 102, thereby adapting to bus signal interfaces such as MIDI (Musical Instrument Digital Interface) on the output interface board, enabling the equipment control signal to be output as control commands to the preset switch. The input end of this output interface board can be connected to the main control board module 102 via the bus conversion board, and the output end is connected to the preset interconnect expansion bus and serves as the output end of the output interface board module 103. Therefore, the output interface board module 103 can simultaneously support MIDI signal transmission and adapt to the MIDI control protocols of various heterogeneous performance equipment. As a summary interface for external control signals, it can distribute the equipment control signals of the main control board module 102 as control commands to various performance equipment via the preset switch. Specifically, it receives the equipment control signals of the main control board module 102 transmitted via the bus conversion board, outputs them to the preset switch, and then the preset switch distributes them to various performance equipment.

[0060] like Figures 1-3 As shown, the first digital processing unit 201 and the second digital processing unit 202 can be the main processing units of the main control board module 102. Specifically, they can be implemented using a microprocessor (i.e., a DSP processor) based on digital signal processing technology (DSP). Internally, they can adopt a Harvard architecture that separates programs and data, and have a dedicated hardware multiplier, which can be used to quickly implement various digital signal processing.

[0061] The aforementioned at least one analog control signal output by the touch display module 101 can be input to the main control board module 102 through a preset analog signal interface, and after being processed by analog-to-digital conversion in advance, at least one corresponding digital control signal is generated, so that the digital control signal can also include relevant performance control information or digital signals that call the performance control information.

[0062] The first real-time data can be temporary data related to the control commands of the performance equipment and / or real-time data on equipment status feedback.

[0063] The temporary data related to control commands can include synchronous control parameters for multi-equipment linkage, allowing control commands to be issued simultaneously to lighting, sound, and mechanical equipment. Furthermore, it can include dynamic command sequences preset in the program timeline, temporary commands for emergency stop / emergency control, and emergency commands for sudden equipment malfunctions during the performance (such as the "lights off, machinery stop, sound mute" command immediately generated by the first digital processing unit 201 when an operator presses the "one-button emergency stop"). This temporary data can be temporarily stored in storage modules such as Synchronous Burst Static Random Access Memory (SBSRAM) (as described in the first accessor 212 below), enabling rapid recall and execution upon reaching the designated time point, ensuring simultaneous triggering of multiple effects.

[0064] In addition, real-time equipment status feedback data can include equipment operating status parameters, feedback data on the equipment moving to the target location according to instructions, environmental and equipment operating condition data, real-time temperature feedback from lighting equipment in outdoor live-action performances, and signal-to-noise ratio feedback from audio equipment. This real-time data can also be temporarily stored in SBSRAM, and the corresponding first digital processing unit 201 or second digital processing unit 202 can quickly determine whether it has exceeded the predetermined safety threshold.

[0065] Furthermore, the preset first control data can be related data from the preset system startup program and fixed performance equipment control logic of the centralized control platform system. For example, it can involve parameters related to the driver program of units or modules such as analog-to-digital converters that are automatically initialized when the system starts, so that they can recognize the standardized voltage / current analog control signals input from the analog signal interface and ensure the normal conversion of analog signals to digital signals; in addition, it can be related parameters for the startup of the underlying program based on the TCP / IP protocol, realizing the 4G / 5G network connection between the centralized control platform system 100 and the cloud and preset switches, ensuring the stable transmission of remote control commands; moreover, it can also be the fixed control logic of the fixed emergency stop driver program that directly cuts off the power supply signal of mechanical equipment when the one-button emergency stop is operated, so as to achieve millisecond-level shutdown without complex calculations and avoid the occurrence of stage machinery accidents; and it can also be the basic configuration data and performance control planning data of each performance equipment read from the first flash memory 213 when the centralized control platform system starts, so that it can be quickly loaded into the first digital processing unit 201, shortening the system startup time. Therefore, the first digital processing unit 201 can use the first real-time data and the preset first control data to perform concurrent processing on at least one digital control signal and generate multiple matching equipment control signals.

[0066] The second real-time data can be similar to the first real-time data, and the second control data can be similar to the first control data. The digital control signals from the first digital processing unit 201 can be further transmitted to the second digital processing unit 202. The second digital processing unit 202 can perform calculations and processing based on each digital control signal to generate corresponding signal reference information. This signal reference information can be information about the performance control parameters (such as light brightness, color, duration, and time) related to the control of the corresponding performance equipment associated with the digital control signal. For the same digital control signal corresponding to the equipment control signal generated by the first digital processing unit 201, the second digital processing unit 202 can perform corresponding signal parsing processing. The signal parsing information can be the performance control parameters of the performance equipment corresponding to the equipment control signal.

[0067] Therefore, for the same digital control signal, the signal reference information generated by the second digital processing unit 202 using the second real-time data and the preset second control data, and the signal analysis information corresponding to the equipment control signal sent by the first digital processing unit 201, can be directly compared. Specifically, the performance control parameters of each piece of equipment can be compared to see if they correspond. For example, the performance control parameters included in the signal analysis information of equipment control signal A (corresponding to the first digital processing unit 201) analyzed by the second digital processing unit 202 are "performance equipment number ax1002, brightness 300 nits", while the performance control parameters included in the signal reference information of digital control signal B (corresponding to equipment control signal A generated by the first digital processing unit 201) are "performance equipment number ax1002, brightness 3000 nits". If the comparison results are inconsistent, it indicates that there is a deviation in the equipment control signal. Usually, the signals can be recalculated based on the two digital processing units and then compared again. Typically, the corresponding equipment control signal can only be output when the comparison results are consistent.

[0068] Therefore, compared to the complex or overly simplistic processing logic of existing dual digital processing units, the centralized control platform system described in this embodiment of the invention can ensure targeted, efficient, and accurate processing of the logic, while effectively avoiding the problems of poor reliability, low processing accuracy, and low efficiency caused by complex logic. It also greatly simplifies the hardware structure of the main control board module, significantly reduces its integration cost, and achieves higher system reliability. Furthermore, the dual digital processing units enable effective processing of signal data, avoid redundant data processing, improve computational efficiency, and ensure the consistency of control logic, thereby guaranteeing the accuracy of the output signal.

[0069] like Figures 1-3As shown, according to an embodiment of the present invention, the main control board module 102 further includes an analog-to-digital conversion unit 203.

[0070] The analog-to-digital conversion unit 203 receives at least one analog control signal through a preset analog signal interface, performs analog-to-digital conversion on the at least one analog control signal, generates at least one digital control signal, and outputs it to the first digital processing unit.

[0071] Analog-to-digital conversion (ADC) is primarily used to convert continuous or discontinuous analog control signals into discrete digital signals. Therefore, the ADC unit 203 must at least have the core function of converting analog voltage signals into digital format so that the first digital processing unit 201 and the second digital processing unit 202 can process them.

[0072] Therefore, the analog-to-digital conversion unit 203 can convert the corresponding analog control signals one by one or in parallel into the corresponding digital control signals, thereby achieving one-to-one accurate analog-to-digital conversion of the signals, so as to facilitate targeted processing by the subsequent digital processing unit.

[0073] like Figures 1-3 As shown, according to an embodiment of the present invention, the analog-to-digital conversion unit 203 further includes an analog-to-digital converter 231 and a signal output queue 232.

[0074] The analog-to-digital converter 231 performs analog-to-digital conversion on at least one received analog control signal, generates at least one digital control signal, and outputs it.

[0075] The signal output queue 232 arranges the output of at least one digital control signal and outputs it to the first digital processing unit in sequence.

[0076] The analog-to-digital converter 231 (ADC) can receive analog control signals (such as analog signals generated by voltage or current signals when adjusting equipment parameters via touch control) generated by the touch display module 101 in the performance scene through a preset analog signal interface. The ultimate control purpose of these analog control signals is to achieve performance control requirements such as real-time adjustment of equipment brightness and running speed.

[0077] The analog-to-digital converter 231 can be used to convert these analog control signals into a signal format that can be recognized by the digital processing unit, i.e., digital control signals. Previously, the original analog control signals could be preprocessed and standardized to make them into standard analog signals that the analog-to-digital converter 231 can receive for analog-to-digital conversion, rather than directly converting analog signals into digital control signals.

[0078] The signal output queue 232 can be a first-in-first-out (FIFO) signal allocation queue, which can forward the first request signal and queue the subsequent request signals. The input side of the signal output queue 232 is connected to the output side of the analog-to-digital converter 231, and its output side is connected to the input side of the first digital processing unit 201. This allows the digital control signals generated by the analog-to-digital converter 231 to be sent to the corresponding first digital processing unit 201 through a FIFO design.

[0079] The analog-to-digital converter 231 converts analog control signals into digital control signals, which are then output to the first digital processing unit 201 via the signal output queue 232. The first digital processing unit 201 performs digital processing on the digital control signals to generate equipment control signals such as discrete binary digital signals. The input side of the analog-to-digital converter 231 is connected to a preset analog signal interface to receive input analog signals.

[0080] The analog-to-digital converter 231 and the signal output queue 232 ensure stable and orderly transmission of digital signals to the first digital processing unit 201, effectively preventing data loss or congestion. Furthermore, the input side of the signal output queue 232 is connected to the analog-to-digital converter 231, enabling effective reception of digital control signals, while its output side is connected to the first digital processing unit 201 on the left, ensuring effective transmission of buffered digital signals. Therefore, after the analog-to-digital converter 231 converts the standardized analog control signals into binary digital control signals, they can be directly transmitted to the signal output queue 232. The core function of the signal output queue 232 is buffering, storage, and orderly transmission, effectively solving the mismatch between the analog-to-digital conversion speed of the analog-to-digital converter 203 and the digital processing speed of the first digital processing unit 201. Simultaneously, it ensures that the signal format, encoding rules, and signal control parameters remain unchanged.

[0081] Among them, the digital control signal of the performance control command can be a standardized binary digital encoding format. After conversion by analog-to-digital converter 231, the signal format remains unchanged, and the signal transmission in the signal output queue 232 is a distortion-free transmission.

[0082] like Figures 1-3 As shown, according to an embodiment of the present invention, the first digital processing unit 201 includes a first digital processor 211, a first accessor 212 and a first flash memory 213.

[0083] The first digital processor 211 calls the first real-time data that is temporarily read and written and the preset first control data to generate multiple equipment control signals with at least one digital control signal;

[0084] The first access device 212 is connected to the first digital processor 211 and stores the first real-time data for the first digital processor 211 to call;

[0085] The first flash memory 213 is connected to the first digital processor 211 and stores preset first control data for the first digital processor 211 to call.

[0086] The first digital processor 211 can be implemented using a microprocessor (i.e., a DSP processor) with digital signal processing technology (DSP), such as the TMS320C6201-DSP processor, which is mainly used to generate equipment control signals as described above.

[0087] In one embodiment of the present invention, the first digital processor 211 can be responsible for core instruction processing and general control, receive the original digital signal transmitted by the signal output queue 232, parse it into clear performance control requirements, and encapsulate it into standardized instructions in a unified system protocol format as equipment control signals, thereby effectively ensuring that the instruction format is unified and recognizable.

[0088] The first access unit 212 can be implemented using a storage module with similar storage and retrieval functions, such as Synchronous Burst Static Random Access Memory (SBSRAM), like 256K SBSRAM. With the help of the first access unit 212, temporary data (i.e., first real-time data) can be stored and retrieved quickly during the performance control process, thereby significantly improving the processing speed and accuracy of the first digital processor 211. Specifically, the first access unit 212 can quickly read temporary data related to equipment control commands, such as light brightness values, mechanical movement speed, and sound volume levels, after preprocessing by the first digital processor 211. Simultaneously, it temporarily writes the original digital control signals input from the signal output queue 232 and intermediate calculation results during the processing, forming the first real-time data for rapid retrieval by the first digital processor 211, thus significantly improving processing efficiency.

[0089] The first flash memory 213 can be implemented using a storage module with similar storage and retrieval functions, such as a 256K Flash ROM, like a Flash Read Only Memory (Flash ROM). With the help of the first flash memory 213, the aforementioned preset first control data can be stored and retrieved during the performance control process, thereby further ensuring the processing speed and accuracy of the first digital processor 211. Specifically, during the system startup of the centralized control platform system 100 in this embodiment of the invention, the first digital processor 211 reads the system's core control program from the first flash memory 213, and during system upgrades and program updates, the optimized core program and other content can be written into the first flash memory 213 to overwrite the original first control data.

[0090] The first digital processor 211 is connected to the signal output queue 232, so that it can receive digital control signals from the signal output queue 232, perform real-time calculation, parsing and preprocessing on the digital control signals, so that the final generated equipment control signals can conform to the standardized digital control instructions of the unified network protocol of the centralized control platform system 100, and can include clear control objectives, operation types, parameter configurations and protocol identifiers, etc.

[0091] The preprocessing stage enables structured and protocol-encapsulated signals, ensuring that the final equipment control signals, as control commands, meet the high reliability and high coordination requirements of large-scale performances with precision, security, compatibility, and synchronization. This guarantees multi-equipment compatibility, resolves the interfacing challenges of heterogeneous performance equipment in pre-set switches, ensures consistent control precision, improves performance effects and quality, enhances equipment operational safety by mitigating overload or malfunction risks, and optimizes command transmission and execution efficiency to guarantee real-time signal performance. Furthermore, the entire signal protocol encapsulation process can further improve overall computational efficiency.

[0092] Furthermore, the first digital processor 211 can be further connected to the first memory 212 and the first flash memory 213 to realize data reading and writing and / or program loading. Regarding the program reading and writing process, the system program and fixed control logic related to the centralized control platform system stored in the first control data stored in the first flash memory 213 can be used to load a fixed program onto the first digital processor 211 when the system starts, ensuring the fixed execution of the performance control functions of various performance equipment. For example, after the system starts, this driver program can be loaded into the first digital processor 211. When adjusting the brightness of the lights (e.g., through physical operation tools such as push rods), the first digital processor 211 can use this program to parse the digitally encoded digital control signal sent by the signal output queue 232 into a control requirement of "brightness 80%", and then further encapsulate it into a standard instruction of "message header + operation bit + parameter" as the equipment control signal, ensuring that the signal instruction ultimately maintains a consistent format. Furthermore, the first digital processor 211 can automatically add timing compensation parameters in a coordinated performance control scenario by loading the signal transmission delay differences of the startup programs for performance equipment such as lights, sound, and machinery from the first control data, ensuring that "lights gradually change + sound gradually increases + machinery rises" is executed simultaneously. Moreover, the first digital processor 211 can also interact with the signal output queue 232 through this program loading, stably receiving the digital control signals after analog-to-digital conversion by the analog-to-digital converter 231, thereby greatly minimizing data loss.

[0093] In summary, the first digital processing unit 201 can, based on the first digital processor 211 and the matching first accessor 212 and first flash memory 213, read or store dynamic temporary data and solidified core programs that support performance control on demand, and realize the parsing of digital control signals and the efficient and accurate generation of equipment control signals by calling these first real-time data and first control data in the subsequent digital control signal processing.

[0094] like Figures 1-3 As shown, according to an embodiment of the present invention, the second digital processing unit 202 includes a second digital processor 221, a second accessor 222, and a second flash memory 223.

[0095] The second digital processor 221 calls the second real-time data that is temporarily read and written and the preset second control data to generate signal reference information corresponding to at least one digital control signal, and generates signal parsing information of multiple equipment control signals output by the first digital processing unit 201.

[0096] The second access device 222 is connected to the second digital processor 221 and stores the second real-time data for the second digital processor to access;

[0097] The second flash memory 223 is connected to the second digital processor 221 and stores preset second control data for the second digital processor to call.

[0098] Similar to the aforementioned first digital processor 211, the second digital processor 221 can also be implemented using a DSP processor (such as the TMS320C6201-DSP processor) to parse the equipment control signals generated by the first digital processor 211 to generate signal parsing information, and can also be used to generate signal reference information for the corresponding digital control signals.

[0099] In one embodiment of the present invention, the second digital processor 221 can also be responsible for core instruction processing and general control, receiving the equipment control signal and the corresponding digital control signal generated by the first digital processor 211, and performing parsing processing on the digital control signal based on performance control information to generate corresponding signal reference information; at the same time, the second digital processor 221 can further parse the corresponding equipment control signal for performance control information to generate corresponding signal parsing information. The parsing processing of the signal reference information and the signal parsing information can be implemented using the same or similar signal parsing technology to effectively ensure the uniformity of the format and the identifiability of the two information.

[0100] The second access unit 222 can also be implemented using a storage module with similar store-and-recall functions, such as a 256K SBSRAM, like a synchronous burst static random access memory. With the help of the second memory 222, temporary data (i.e., second real-time data) can be stored and recalled quickly during the performance control process, thereby significantly improving the processing speed and accuracy of the second digital processor 221. Specifically, the second memory 222 can quickly read temporary data related to various equipment control instructions preprocessed by the second digital processor 221, and simultaneously temporarily write the original digital control signals generated by the first digital processor 211, equipment control signals, and intermediate calculation results summarized during the processing, forming second real-time data for the second digital processor 221 to recall quickly, thus rapidly improving processing efficiency.

[0101] The second flash memory 223 can be implemented using a storage module with similar storage and retrieval functions, such as a read-only flash memory, like a 256K Flash ROM. With the help of the second flash memory 223, the aforementioned preset second control data can be stored and retrieved during the performance control process, thereby further ensuring the processing speed and accuracy of the second digital processor 221. In this embodiment of the invention, when the system starts, the second digital processor 221 reads the system's core control program from the second flash memory 223. During system upgrades and program updates, optimized core programs and other content can be written into the second flash memory 223 to overwrite the original second control data.

[0102] Temporary data related to equipment control commands based on the same performance control process and various real-time data of performance equipment working status feedback are stored in the first memory 212 and the second memory 222 respectively, which can generate first real-time data and second real-time data; at the same time, during the program startup and calling process of the same performance control process, the corresponding program startup and calling parameters, including system program parameters and fixed control logic information, can be synchronously stored in the first flash memory 213 and the second flash memory 223 respectively, so as to generate first control data and second control data.

[0103] Thus, the equipment control signals generated by the first digital processor 211 can be judged and identified by the second digital processor 221 based on the same data, thereby effectively preventing signal processing deviations generated by the first digital processor 211, ensuring the accuracy and effectiveness of performance control commands, and providing an alternative control method based on chip module design for the performance control process.

[0104] In some embodiments, when the comparison result information corresponding to the signal reference information of the digital control signal and the signal parsing information of the equipment control signal is inconsistent, the second digital processor 221 can further perform special adaptation and collaborative optimization on the equipment control signal from the first digital processor 211 based on the rules in the preset protocol management component library, to achieve further optimization processing of the equipment control signal, correct the correct performance control parameters to the latest equipment control signal, and at the same time send the updated equipment control signal from the second digital processor 221 to the first digital processor 221. The parsing parameters of the secondary equipment control signal generated by the first digital processor 221 based on the corresponding digital control signal are compared again. When the parameters of the two are consistent, the comparison is completed. In other words, when the first comparison fails, the second digital processor 221 will regenerate the equipment control signal based on the original digital control signal, that is, the updated equipment control signal. The updated equipment control signal is sent to the first digital processor 211. The first digital processor 211 then parses the updated signal, generating updated signal analysis information. Simultaneously, it generates a secondary equipment control signal based on the original digital control signal, obtaining signal reference information for the secondary signal. These two signals are compared again. When the comparison is complete and the signal reference information matches the updated signal analysis information, the secondary or updated equipment control signal is output. This effectively ensures the verification process of signal processing, guarantees the accuracy of equipment control commands during the performance control process, ensures smooth performance control, and minimizes various control failures. It also avoids placing excessive data processing pressure on the main control board module 102 and enables coordinated processing between the first digital processor 211 and the second digital processor 221, significantly improving the processing efficiency and accuracy of the equipment control signal and preventing the backlog of digital control signals in the signal output queue 232. Since the equipment control signal can include the manufacturers, models, and data / signal protocols of various heterogeneous performance equipment, it effectively solves the compatibility issues of various heterogeneous equipment.

[0105] It should be noted that, in the embodiments of the present invention, based on different signal processing scenarios and processing times, at least one of the aforementioned analog control signals, digital control signals, equipment control signals, updated equipment control signals, and secondary generated equipment control signals may be present simultaneously. Those skilled in the art should know that the foregoing description is for the convenience of understanding the solution and does not provide further details on the number, type, etc. of these signals.

[0106] The second digital processor 221 can receive equipment control signals and corresponding digital control signals from the first digital processor 211, perform real-time calculations, parsing, and preprocessing on these signals, and work with the first digital processor 211 to ensure that the final generated equipment control signals conform to the standardized digital control instructions of the unified network protocol of the centralized control platform system 100, and can include clear control objectives, operation types, parameter configurations, and protocol identifiers. The calculation, parsing, and preprocessing processes are described above and will not be repeated here. Furthermore, the second digital processor 221 can be further connected to the second memory 222 and the second flash memory 223 to realize data reading and / or program loading. The data reading and / or program loading processes of the second digital processor 221 can also refer to the relevant content of the first digital processor 211 described above and will not be repeated here.

[0107] Therefore, the second digital processing unit 202 can be responsible for the calculation of another part of the control tasks, mainly for the decomposition, supplementation, and other collaborative optimization of the control task results of the first digital processing unit 201 (in some cases, it can also realize the interchangeability of task functions, as described above). Specifically, it involves protocol adaptation and compatibility calculations for heterogeneous performance equipment, timing synchronization and collaborative calculations for multi-equipment linkage, offloading calculations for high-concurrency control tasks, and special calculations for safety mechanisms and emergency control, etc., all of which can be reflected in the output parameters of the final equipment control signals. Therefore, the second digital processing unit 202 and the first digital processing unit 201 can effectively realize the supplementation, extension, and collaborative enhancement of control tasks, and have a master-slave collaborative, complementary division of labor, and data interoperability relationship. At the same time, their respective memory and flash memory can provide reading and writing of corresponding temporary data and control logic data, such as dynamic temporary data that needs to be read and written quickly, updated in real time, and called frequently during the performance.

[0108] In summary, the second digital processing unit 202, based on the second digital processor 221 and the matching second memory 222 and second flash memory 223, can verify and coordinate the signal processing of the first digital processing unit 201. It can read or store dynamic temporary data and solidified core programs supporting performance control as needed. Furthermore, in the subsequent processing of digital control signals, it can call these second real-time data and second control data to parse digital control signals and equipment control signals, ensuring the accuracy and effectiveness of equipment control signals and improving the processing efficiency of the entire main control board module 102. Moreover, the entire main control board module 102 has an extremely simple structural design, controllable cost, and can guarantee control accuracy and reliability.

[0109] like Figures 1-3 As shown, according to an embodiment of the present invention, the main control board module 102 further includes a dual-port interaction unit 204.

[0110] The dual-port interaction unit 204 is connected to the first digital processing unit 201 and the second digital processing unit 202 respectively, and is used to realize data forwarding and interaction between the first digital processing unit 201 and the second digital processing unit 202.

[0111] The dual-port interaction unit 204 can be constructed based on a random access memory or similar module or unit with two independent data ports, such as a dual-port RAM. Therefore, one port of the dual-port interaction unit 204 can be connected to the first digital processor 211, and the other port can be connected to the second digital processor 221. This effectively ensures data interaction and signal communication between the two digital processors, thereby greatly improving the overall computing efficiency of the main control board module 102. Thus, the data that the dual-port interaction unit 204 can process can be dynamic data that can be shared in real time and used for joint decision-making during the respective operations of the two digital processors. This effectively eliminates static redundant information, avoids repeated data processing, significantly improves computing efficiency, ensures the consistency of the control logic of the two digital processors, and, through real-time data sharing, ensures that the division of labor between the two digital processors is seamless and their coordination is error-free.

[0112] like Figures 1-3 As shown, according to an embodiment of the present invention, the main control board module 102 further includes a bus forwarding unit 205.

[0113] The bus forwarding unit 205 has its input terminals connected to the first digital processing unit 201 and the second digital processing unit 202, respectively, and its output terminal connected to a preset interconnection expansion bus.

[0114] For both digital processing units, the final confirmed equipment control signal can be sent to the preset interconnection expansion bus simultaneously via the bus forwarding unit 205, thereby completing the transmission of performance control commands to the preset switch. The bus forwarding unit 205 can be a bridge controller module that performs format conversion and forwarding of equipment control signals based on the preset interconnection expansion bus protocol, such as a bus data relay transmission unit implemented based on the PCI2040 DSP-PCI driver.

[0115] Two digital processors can be connected to the bus forwarding unit 205 respectively, and transmit the PCI conversion performance control command corresponding to the equipment control signal to the final PCI bus () and PCI2040 (PCI to DSP bridge controller), and transmit the final control command to the peripheral component interconnect standard bus (i.e. PCI bus), thereby realizing the communication between the main control board module 102 and the external preset interconnect expansion bus, and realizing the purpose of the main control board module 102 to transmit control commands to the outside.

[0116] Among them, the bus forwarding unit 205 can use a preset bus interface (such as a PCI bus interface) as the communication interface between the main control board module 102 and external devices (such as a preset switch), and transmit the final performance control command through the preset interconnection expansion bus to realize the coordinated control of multiple equipment.

[0117] like Figures 1-3 As shown, according to an embodiment of the present invention, the centralized control platform system 100 applied to the control of large-scale exhibition equipment further includes an alternative control module 104.

[0118] The alternative control module 104 is connected to the main control board module 102 and generates at least one alternative analog signal in response to manual control operation and sends it to the main control board module 102.

[0119] like Figure 3 As shown, the alternative control module 104 can be a control replacement module for the touch display module 101. That is, when the touch display module 101 cannot realize the touch display function, the alternative control module 104 and the main control board module 102 can realize the control of the corresponding performance equipment, which can focus on the rapid control of the core performance functions, rather than text input.

[0120] The optional control module 104 may include various functions such as keyboard control board, standard keyboard, motherboard reset button, hard drive and USB flash drive, etc., for performance control, data storage and retrieval. The keyboard control board may include left keyboard control board, middle control board and right keyboard control board, etc., which can be responsible for different dimensions of performance control, such as lighting control (main light start / stop, brightness / color temperature quick adjustment, lighting scene switching, such as "prelude lighting effect" "climax lighting effect"), sound control (volume increase / decrease, sound effect mode switching, background sound start / stop, microphone gain adjustment), mechanical control (stage lifting / rotation start / stop, prop mechanical arm action triggering, lighting truss lifting control) and scene linkage dimension (multi-equipment linkage scene triggering, emergency pause / stop triggering).

[0121] Specifically, the left keyboard control panel can control lighting and video equipment, such as binding buttons for "start / stop main stage color-changing lights," "LED screen image switching," and "laser effect triggering," focusing on the rapid operation of visual equipment; the middle keyboard control panel can realize core linkage and safety control, such as binding core functions like "scene switching," "three-button control," and "one-button emergency stop," serving as the main control hub for the performance process; the right keyboard control panel can control audio and mechanical equipment. The keyboard control panels can connect to a keyboard conversion card via a CAN bus (Controller Area Network), and further connect to the main control board module 102 via this conversion card. Specifically, the keyboard conversion card can be implemented as a USB-CAN conversion card, meaning it can connect to the main control board module 102 via a USB protocol interface.

[0122] The motherboard reset button can also be connected to the main control board module 102 via a USB interface. The motherboard reset button primarily serves the core function of one-button reset, which aims to resolve system anomalies and quickly restore normal system operation. For example, when the main control board module 102 crashes or becomes unresponsive due to program lag, data conflicts, or abnormal device linkage, triggering the reset button can force a restart of the main control board module, quickly clearing the abnormal state and restoring the initial operating logic. Specifically, if the control interface freezes during a performance and cannot issue a "lights off" command, the motherboard reset button can be used to generate a reset signal to the main control board module 102, restarting it and restoring its normal control functions, allowing subsequent operations to continue.

[0123] Unlike keyboard control panels, which require no text input and directly link devices for real-time performance control, standard keyboards are primarily used for text input and system configuration. Command control is mainly managed by the main control board module 102, such as inputting device models, editing user accounts, modifying system parameters, updating loading programs, and setting touch shortcuts. Therefore, standard keyboards, through a USB-based interface, enable human-computer interaction, ensuring rapid input of text commands and shortcut key operations.

[0124] The hard drive and USB flash drive can also be directly connected and communicated with the main control board module 102 via the USB protocol interface, enabling functions such as reading and writing system programs and performance data.

[0125] In summary, the alternative control module 104 further provides dual control protection for the overall centralized control platform system 100, ensuring emergency switching of control facilities in case of failures in various control methods such as touch display, thereby effectively guaranteeing the smooth and efficient operation of the entire system for performance control. Figures 1-3As shown, according to an embodiment of the present invention, the centralized control platform system applied to the control of large-scale exhibition equipment also includes a power conversion module 105.

[0126] The power conversion module 105 is connected to the main control board module 102 via a preset universal serial bus. It is used to convert power supply to the main control board module 102 and to convert power supply to the touch display module 101 via a preset backlight power supply connected to it. At the same time, it receives the input voltage of the preset power supply.

[0127] The power conversion module 105 can be a power voltage / current conversion control unit connected to the power supply and implemented based on the power conversion board. Specifically, it can directly use the USB protocol interface to realize the power conversion of the main control board module 102. At the same time, it can also realize communication and interaction with the main control board module 102 to obtain feedback on the power supply status information of the main control board module 102, such as whether the power supply voltage is normal and stable, and related time and voltage information.

[0128] Furthermore, the power conversion module 105 can also power the touch display module 101 using a preset backlight power supply, enabling the touch display module 101 to perform functions such as touch detection, operation feedback, and interface display normally. In addition, the power conversion module 105 can also supply power to modules such as the alternative control module 104 and the output interface board module 103, converting external power to voltages suitable for each module, thus providing more stable power support for the entire system. According to embodiments of the present invention, any multiple modules among the touch display module 101, main control board module 102, output interface board module 103, alternative control module 104, and power conversion module 105 can be combined into one module, or any one of these modules can be split into multiple modules. Alternatively, at least some functions of one or more of these modules can be combined with at least some functions of other modules and implemented in one module. According to embodiments of the present invention, at least one of the touch display module 101, main control board module 102, output interface board module 103, alternative control module 104, and power conversion module 105 can be at least partially implemented as hardware circuits, such as field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), systems-on-a-chip, systems-on-a-substrate, systems-on-package, application-specific integrated circuits (ASICs), or any other reasonable means of integrating or packaging circuits, or implemented in hardware or firmware, or in any one of software, hardware, and firmware implementations, or in a suitable combination of any of these. Alternatively, at least one of the touch display module 101, main control board module 102, output interface board module 103, alternative control module 104, and power conversion module 105 can be at least partially implemented as a computer program module, which can perform corresponding functions when the computer program module is run.

[0129] Based on the aforementioned centralized control platform system applied to the control of large-scale exhibition equipment, this invention also provides a control method for the centralized control platform system applied to the control of large-scale exhibition equipment. The following will be combined with... Figure 4 The control method is described in detail.

[0130] like Figure 4 As shown, another aspect of the present invention provides a control method for the above-mentioned centralized control platform system applied to the control of large-scale exhibition equipment, which includes operation S401 and operation S402.

[0131] In operation S401, at least one analog control signal is generated in response to touch operation detection;

[0132] In operation S402, in response to the at least one analog control signal, a plurality of equipment control signals are generated and output to a preset switch, which further includes sub-operations S421 and S422.

[0133] In sub-operation S421, at least one digital control signal corresponding to the at least one analog control signal input based on the preset analog signal interface is received, and the first real-time data temporarily read and written and the preset first control data are called to generate the multiple equipment control signals.

[0134] In sub-operation S422, the second real-time data for temporary reading and writing and the preset second control data are called to generate signal reference information corresponding to the at least one digital control signal, and to generate signal parsing information for the multiple equipment control signals. Based on the comparison result between the signal reference information and the signal parsing information of the corresponding equipment control signal, the multiple equipment control signals are output.

[0135] Regarding the above, Figure 4 For details on the control methods and corresponding technical effects of the centralized control platform system shown, please refer to the aforementioned examples.
